Aspirin in diabetic patients at primary prevention: insights of the VITAL cohort

PURPOSE

Aspirin use among patients with diabetes in primary prevention is still a matter of debate. We aimed to evaluate the potential cardiovascular risk benefit of aspirin in primary prevention, using data from a contemporary cohort.

METHODS

Retrospective analysis of the VITAL cohort with > 20,000 individuals at primary prevention who were followed for a median of 5.3 years. The population was evaluated according to the baseline diabetes status, and then aspirin use was evaluated among diabetic patients. Cox regression models were used to estimate the risks of mortality and cardiovascular outcomes. The estimates were reported using adjusted hazard ratio (HR) and 95% confidence intervals (95%CI).

RESULTS

Diabetic patients (n = 3549; 13.7%) showed to increase the risk of all-cause mortality (HR 1.61, 95%CI 1.33-1.94), and major adverse cardiovascular events (MACE) (HR 1.36 95%CI 1.11-1.68) than non-diabetic population. Diabetic patients taking aspirin were older, more frequently man, hypertensive, current users of statins, and current smokers compared with diabetic patients who did not use aspirin at baseline. There was no difference between diabetic aspirin users and non-users regarding all-cause mortality (HR 0.80, 95%CI 0.59, 1.10), MACE (HR 0.92, 95%CI 0.64, 1.33), coronary heart disease (HR 0.98, 95%CI 0.67, 1.43), or stroke (HR 0.87, 95%CI 0.48, 1.58).

CONCLUSIONS

The VITAL data confirmed diabetes as an important risk factor for cardiovascular events in a contemporary cohort but did not show cardiovascular benefits of aspirin in primary prevention among people with diabetes who were shown to be at higher risk of cardiovascular events.

Coronary inflammation by computed tomography pericoronary fat attenuation in young male anabolic androgenic steroid users

Background

The illicit use of anabolic androgenic steroids (AAS) has been associated with diminished cholesterol efflux mediated by HDL, remarkable decrease in high-density lipoprotein (HDL) plasma concentration and subclinical coronary artery disease (CAD). Inflammation is the key to the atherogenic process associated with atherosclerotic plaque vulnerability. The pericoronary mean fat attenuation (pFAM) has emerged as a marker of coronary inflammation and can predict future cardiovascular events, which is measurable from standard coronary computed tomography angiography (CCTA). However, whether AAS abuse has a role in pFAM in young male AAS users is unknown.

Purpose

The aim of this study was to evaluate whether AAS abuse could leads to higher pFAM and premature coronary inflammation in young male AAS users.

Methods

Twenty strength-trained AAS users (AASU) age 29±5 yr, 20 age-matched strength-trained AAS nonusers (AASNU), and 10 sedentary controls (SC) were enrolled in this study. Coronary inflammation was assessed by pFAM-CCTA in the right coronary artery (RCA), left anterior descending artery (LDA) and left circumflex coronary artery (Cx).

Results

pFAM in the RCA was significantly higher in AASU compared with AASNU and SC (−64.59±9.45 vs. −79.21±6.67 vs. −80.97±7,91 Hounsfield Units (HU), respectively, p<0.001]. Also, the pFAM in the LAD was higher in AASU compared with AASNU and SC (−72.83±7.21 vs. −79.41±6.72 vs. −80.97±7.72 HU, p=0.006). However, no difference to pFAM in the Cx between AASU, AASNU and SC (−74.30±5.85 vs. −79.77±7.13 vs. −78.19±5.82 HU, respectively, p=0.069) was found.

Conclusion

This study indicates that AAS abuse may be associated with higher pFAM and premature coronary inflammation in the RCA and LAD. The higher pFAM may be linked to early development of CAD in young AAS users.

Outcomes in pregnant women with valvular heart disease from sub Saharan Africa transferred to a developed nation. A distinct care model

Background

Pregnant women with valvular heart disease (VHD) in African countries still bear a disproportionate burden of maternal morbidity and mortality, due to the reduced accessibility to health care and the scarcity of skilled professionals. It is unclear if outcomes would be improved by care-delivery model changes.

Purpose

We performed a clinical audit of African pregnant women with VHD who were transferred for their care from five countries to our cardio-obstetrics unit, during a twenty-year period, through a memorandum of agreement of international cooperation.

Methods

A retrospective analysis of 81 pregnancies (P) in 45 African women with VHD (median age 24, IQR 22–29 years) from 2001 to 2020. The main outcome measures were major maternal complications and perinatal outcome.

Results

History of rheumatic heart disease was determined in 74.1% of the P. Most women were in NHYA I or II before P (79.0%), 43.2% had previous cardiac medication and 60.5% were anticoagulated (33.3% with acenocoumarol and 27.2% with warfarin). 59.3% of P had at least one valvular prosthesis, including 38 mechanical prosthetic valve (MPV) and 10 biological valves. 22.2% had prior surgical or percutaneous VHD correction, excluding prosthesis implantation. At baseline, impaired left ventricular ejection fraction was found in 12.3%. Previous arrhythmic event, stroke or infectious endocarditis were found in 12.3%, 8.6% and 6.2% of P, respectively.

During P, deterioration in NYHA functional class occurred in 42.0% and 9.9% required initiation or intensified cardiac medication. For MPV, 51% maintained a vitamin K antagonist, 15.7% used LMWH from 6 to 12th weeks and 9.8% used LMWH throughout P. Valve thrombosis occurred in 4 women (4.9% of P), with one maternal death in a patient with double MPV.

Hemorrhagic complications happened in 8.6% of P, all anticoagulated, in immediate postpartum or puerperal period. The 81 P resulted in 56 live births (69.1%), with a medium birth weight of 3026±471g. Delivery by caesarean section was performed in 28.3% of newborns. The incidence of miscarriage was 23.5% and fetal malformations occurred in 14.8%, with warfarin embryopathy in 4 cases. In univariate analysis, the presence of valvular protheses (p=0.001), and anticoagulation (p=0.001) were related to unsuccessful P. In multivariate analysis, VKA therapy was the unique independent predictor of unsuccessful P (p=0.048).

Conclusion

With the multidisciplinary care provided, pregnancy was relatively well tolerated and successful for women transferred from sub–Saharan Africa. However, the presence of a valvular prothesis is associated with unsuccessful pregnancy even in a developed nation. Efforts other than the implantation of a MPV should be pursued vigorously in sub Saharan Africa.

Effect of exercise training on HDL subclasses and cholesterol transfers to HDL in elderly individuals

Introduction

Lifestyle habits play a crucial role on coronary artery disease (CAD) prevention. Exercise training promotes increase of HDL-C and decrease of plasma triglycerides is an important tool against atherogenesis. HDL-C determination evaluates only partially the HDL status and anti-atherosclerotic potential. A number of other parameters also relates HDL metabolism and function with CAD, such as HDL subclass distribution and cholesterol transfer to HDL, that have been reported as impaired in CAD. It is known that exercise training can improve those parameters in young individuals, but it has not been explored whether this effect can also be obtained in elderly subjects undergoing moderate training.

Purpose

Investigate the effects of regular practice of moderate exercise training on cholesterol transfer to HDL and HDL subclasses distribution in elderly compared to young subjects.

Methods

111 healthy subjects were enrolled in this study, as divided in four groups paired by sex: active elderly (AE, n=25), inactive elderly (IE, n=21), active young (AY, n=40) and inactive young (IY, n=25). All subjects performed cardiopulmonary test to determine VO2 peak and answered a questionnaire about exercise practice; only subjects practicing regular training for at least one year were selected to the 2 “active” groups. Blood samples were collected to determine lipid and apolipoprotein profile. Lipid subfractions were measured using the Lipoprint system. Cholesterol transfer to HDL was performed by incubating plasma with a donor lipoprotein-like nanoparticle containing radioactively labeled unesterified (UC) and esterified cholesterol (EC), followed by chemical precipitation and radioactive count.

Results

Data are shown on Table 1. Higher VO2 peak in both active groups confirmed the effectiveness of the training. HDL-C was higher in AE and AY than in IE and IY; apo A-I was higher in AY than in IY, but AE and IE were equal. UC transfer was higher in AE and AY than in IE and IY, but EC was higher AY than in IY, AE and IE were equal. Large HDL subfraction was higher in AY than in IY, but AE and IE were equal. The intermediate HDL subfraction was higher in AE than in IE. Comparing AE with AY, no differences in UC and EC, as well as HDL subfractions were observed.

Conclusion

Training had the ability to improve parameters of HDL metabolism not only in young but also in elderly subjects and it is remarkable that, despite their lower VO2 peak, in the AE group the cholesterol transfers and the HDL subfraction profile were similar to those of the AY group. Those results confirm the effectiveness of training to improve HDL anti-atherosclerotic features in the elderly.

Evaluation of myocardial work in patients recovered from the severe form of COVID-19

Background/Introduction

The impact of COVID-19 goes beyond its acute form, and can lead to the persistence of symptoms and the emergence of systemic disorders, defined as Post-Covid or Long-Covid.

Purpose

Assess the late impact on the cardiorespiratory system of patients recovered from severe Covid.

Methods

We performed cross-sectional study that included patients over 18 years of age who recovered from the severe form of COVID-19 after at least 60 days of their discharge. Patients and healthy controls were enrolled to perform transthoracic echocardiography (TTE) and cardiopulmonary exercise testing (CPET).

Results

A total of 52 patients and 24 controls were enrolled. The standard TTE parameters (end diastolic diameters, left ventricular ejection fraction, diastolic function and right ventricular systolic function) showed no difference when compared to the control group. When analyzing the myocardial work, there was a higher Wasted MW (GWW): 135 mmHg% vs 84.5 mmHg% (p=0.002), with lower MW Efficiency (GWE): 94 vs. 96 (p=0.003); as well as lower values of global strain: cases = 18.6% vs. 20.1% (p=0.009). No differences were found in the Constructive MW (GWC) and MW Global Index (GWI). In the CPET data we found lower peak values for the VO2: 24 ml/kg/min vs. 32.75 ml/kg/min (p<0.001); for the Heart Rate: 162 bpm vs. 175 bpm (p<0.001); for the Ventilation: 79.3 L/min vs. 109.85 L/min (p<0.001) and Respiratory Exchange Ratio: 1.12 vs. 1.19 (p=0.004). There was no difference in the maximum load reached, neither in the oxygen pulse values and in the Ve/CO2 slope. In relation to the oxygen kinetics, there was a significant reduction in OUES%: 85% vs. 98% (p=0.03); as well as an extended T½: 112 s vs. 88.5 s (p<0.001); and a slowing of the fall in heart rate in recovery time, as measured by the Heart Rate decay: −17.32 bpm vs. −22.08 bpm (p=0.005).

Conclusion

Patients recovered from the severe form of COVID-19 had higher GWW with lower efficiency (GWE). Such findings, added to changes in oxygen kinetics during exercise, may point to a possible cardiocirculatory mechanism associated with decreased aerobic capacity.

Epidemiology and impact of frailty in patients with atrial fibrillation in Europe

BACKGROUND

Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent.

OBJECTIVES

We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients.

METHODS

A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined.

RESULTS

Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty.

CONCLUSIONS

In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

O106 Maximising the benefits of bariatric surgery through targeting ghrelin: a randomised, double-blind, placebo-controlled crossover study in people with suboptimal weight loss after bariatric surgery

Introduction

One in 5 people have a suboptimal weight-loss (WL) response to bariatric surgery. The causes are unclear, but patients report resumed hunger and increased food intake, eating behaviours driven by the orexigenic hormone, ghrelin. This proof-of-concept study aimed to evaluate the impact of reducing circulating acyl-ghrelin, the biologically active isoform, on appetite and energy intake in people with suboptimal WL and aberrant ghrelin profile after bariatric surgery.

Methods

Thirty-five patients with <20%WL from 12 months after Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) and aberrant circulating ghrelin profile underwent 10 days of treatment with a novel, highly-selective ghrelin o-acyltransferase inhibitor, GLWL-01, and placebo. The primary endpoint was within-person change in ad libitum energy intake during a test meal on day 10. Secondary endpoints assessed subjective appetite, food cravings, macronutrient intake, gut hormones, cardiometabolic profile and body composition. Ethical approval was obtained.

Results

Thirty-one participants (26 RYGB, 9 SG) completed both cycles. GLWL-01 produced a 58.9±27.2% decrease in fasting plasma acyl-ghrelin and 29.3±27.1% increase in desacyl-ghrelin after 10 days. Marked reduction in subjective hunger, food cravings and hedonic influence on appetite was observed with GLWL-01, however objective appetite measures – ad libitum and free-living energy intake – did not change. Circulating levels of cardiovascular risk-conferring lipoproteins significantly improved and no adverse impact on glycaemic control was observed.

Conclusion

Pharmacological modulation of the ghrelin system may be used as part of a personalised therapeutic approach to optimise clinical outcomes in patients with suboptimal WL after bariatric surgery.

Take-home message

This first-in-human mechanistic study shows that pharmacological modulation of the ghrelin system is a promising therapeutic strategy for maximising weight loss response to bariatric surgery.

POS0385 “EFFECTIVE LUNG AGE” IN SUBJECTS WITH SYSTEMIC SCLEROSIS-ASSOCIATED INTERSTITIAL LUNG DISEASE (SSc-ILD) IN THE SENSCIS TRIAL

Background

FVC declines gradually with aging. The loss of lung function in patients with progressive SSc-ILD mimics an accelerated ageing process.

Objectives

Using reference equations, we estimated the “effective lung age” of subjects in the SENSCIS trial (i.e. the age of healthy individuals with the same FVC) and compared these estimates to their real age.

Methods

The SENSCIS trial enrolled subjects with SSc-ILD with first non-Raynaud symptom within the prior ≤7 years, extent of fibrotic ILD on HRCT ≥10%, FVC ≥40% predicted, DLco 30–89% predicted. Evidence of recent decline in FVC was not an inclusion criterion. Subjects were randomised to receive nintedanib or placebo. Using reference equations published by the European Respiratory Society Global Lung Function Initiative, based on FVC data from over 70,000 healthy individuals aged 3–95 years from 26 countries, [Quanjer et al. Eur Respir J 2012;40:1324–1343], we estimated the effective lung age of subjects at baseline and at week 52 based on their FVC, sex, ethnicity and height, and compared these effective lung ages with the subjects’ real ages. Three subjects aged <25 years were excluded. The upper limit of effective lung age was considered to be 95 years.

Results

Mean time since onset of first non-Raynaud symptom was 3.5 years in both the nintedanib and placebo groups. At baseline, mean (SD) effective lung age was 83.1 (14.4) years in the nintedanib group (n=287) and 82.9 (14.8) years in the placebo group (n=286). In these groups, respectively, the mean (SD) difference between effective lung age and real age was 28.4 (17.7) and 29.3 (18.5) years and the difference was >20 years in 71.4% and 72.4% of subjects. In the nintedanib and placebo groups, respectively, median (Q1, Q3) effective lung age was 88.4 (74.6, 95.0) and 88.5 (74.7, 95.0) years at baseline and 91.0 (75.2, 95.0) and 95.0 (75.9, 95.0) years at week 52.

Conclusion

At entry into the SENSCIS trial, subjects with SSc-ILD had an effective lung age that was much higher than their real age. Over 52 weeks, the increase in effective lung age was numerically lower in subjects treated with nintedanib than placebo. These data show that marked loss of lung function that can occur in the few years following onset of SSc-ILD and support a benefit of nintedanib in slowing the progression of SSc-ILD.

AB0657 Severity and impact of gastrointestinal symptoms in patients with SSc-ILD treated with nintedanib: data from SENSCIS-ON

Background

Gastrointestinal (GI) involvement is a common manifestation of systemic sclerosis (SSc) and a frequent side-effect of drugs used to treat SSc. In the SENSCIS trial, nintedanib reduced the rate of decline in forced vital capacity (FVC) in patients with SSc-associated interstitial lung disease (SSc-ILD), with an adverse event profile characterised predominantly by GI events.

Objectives

To assess the severity and impact of GI symptoms on quality of life in patients treated with nintedanib in the open-label extension trial, SENSCIS-ON.

Methods

Patients with SSc-ILD who completed the SENSCIS trial or a drug–drug interaction (DDI) study of nintedanib and oral contraceptive were eligible to enter SENSCIS-ON. Patients who received nintedanib in SENSCIS (up to 100 weeks) and continued nintedanib in SENSCIS-ON comprised the “continued nintedanib” group. Patients who received placebo in SENSCIS and initiated nintedanib in SENSCIS-ON, or who received nintedanib for a short time in the DDI study, comprised the “initiated nintedanib” group. We assessed changes in scores on the UCLA Scleroderma Clinical Trial Consortium Gastrointestinal Tract (UCLA SCTC GIT) questionnaire v2.0 from baseline to week 52. This questionnaire comprises 7 scales measuring the severity and impact of GI symptoms: reflux, distension or bloating, faecal soilage, diarrhoea, constipation, emotional well-being, social functioning. Each scale is scored from 0 to 3 except for the diarrhoea scale (0 to 2) and constipation scale (0 to 2.5). The total score, the mean of the scores for the scales except constipation, ranges from 0 to 2.83, with higher scores indicating worse symptoms.

Results

The “continued nintedanib” group comprised 197 patients and the “initiated nintedanib” group comprised 247 patients (231 from SENSCIS). Of these, 178 and 218 patients, respectively, provided a total UCLA SCTC GIT score at baseline. At baseline, mean (SD) total scores were 0.33 (0.33) and 0.33 (0.34) in the continued nintedanib and initiated nintedanib groups, respectively. Mean (SD) scores on the 7 scales ranged from 0.16 (0.52) to 0.70 (0.73) in the continued nintedanib group and from 0.13 (0.43) to 0.64 (0.68) in the initiated nintedanib group. Increases (worsening) in scores were observed in both groups from baseline to week 52, except for on the constipation scale (Figure 1). Based on the total score, between baseline and week 52, the proportion of patients with moderate or severe or very severe GI symptoms increased, but 45.7% and 39.7% of patients in the continued nintedanib and initiated nintedanib groups, respectively, had no or mild GI symptoms at week 52 (Table 1).

Changes in UCLA SCTC GIT scores from baseline to week 52 of SENSCIS-ON

Conclusion

In the SENSCIS-ON trial, the majority of patients with SSc-ILD treated with nintedanib had no or mild GI symptoms at baseline. A small worsening in GI symptoms was observed over 52 weeks. Diarrhoea had the greatest impact, reflecting the adverse event profile of nintedanib. Recommendations for the management of diarrhoea in patients treated with nintedanib should be implemented in clinical practice.

AB0658 Nocebo effect on diarrhoea reported in the SENSCIS trial of nintedanib in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD)

Background

Unfavourable effects observed after administration of placebo that may be attributed to factors such as expectation or conditioning are known as nocebo effects. Prior to initiation of the SENSCIS trial, diarrhoea was a known side-effect of nintedanib.

Objectives

To investigate whether a nocebo effect contributed to reporting of diarrhoea in the SENSCIS trial.

Methods

The SENSCIS trial enrolled patients with systemic sclerosis (SSc) with first non-Raynaud symptom in the prior ≤7 years and ≥10% extent of fibrotic ILD on high-resolution computed tomography. Patients were randomised to receive nintedanib or placebo until the last patient had reached week 52 but for ≤100 weeks. A follow-up visit was conducted 28 days after the end of treatment. Adverse events were reported by investigators irrespective of causality and coded according to the Medical Dictionary for Regulatory Activities. We analysed the incidence of diarrhoea adverse events in the on-treatment period (i.e., events with onset between the first intake of trial drug intake and the last intake plus 7 days) and in the post-discontinuation period (i.e., events with onset between the first day after the on-treatment period and the end of the follow-up period) in the nintedanib and placebo groups. Incidence rates were calculated as the number of patients with diarrhoea adverse events divided by the time at risk.

Results

In the on-treatment period (time at risk: 277.8 patient-years), the rate of diarrhoea adverse events in the placebo group (n=288) was 33.1 per 100 patient-years. In the post-discontinuation period (time at risk: 41.9 patient-years), the rate of diarrhoea adverse events in the placebo group (n=284) was 19.1 per 100 patient-years. In the on-treatment period (time at risk: 105.1 patient-years), the rate of diarrhoea adverse events in the nintedanib group (n=288) was 209.3 per 100 patient-years. In the post-discontinuation period (time at risk: 53.7 patient-years), the rate of diarrhoea adverse events in the nintedanib group (n=283) was 5.6 per 100 patient-years.

Conclusion

In the SENSCIS trial in patients with SSc-ILD, the rate of diarrhoea adverse events in the placebo group fell after trial drug was discontinued. This suggests that a nocebo effect may have contributed to the diarrhoea adverse events reported in the SENSCIS trial.

POS0070 CONTINUED TREATMENT WITH NINTEDANIB IN PATIENTS WITH LIMITED CUTANEOUS SYSTEMIC SCLEROSIS (lcSSc) AND INTERSTITIAL LUNG DISEASE (ILD)

Background

Few data are available on the progression and management of ILD, or the management of adverse events associated with drug treatment, in patients with lcSSc. SENSCIS-ON is an open-label extension trial that is collecting data on decline in forced vital capacity (FVC) and adverse events in patients treated with nintedanib over the long term.

Objectives

To assess decline in FVC and adverse events in patients with lcSSc and ILD treated with nintedanib in SENSCIS-ON.

Methods

Patients with SSc-ILD were eligible to enter SENSCIS-ON if they completed the randomized placebo-controlled SENSCIS trial (in which patients received trial drug until the last patient reached week 52 but for ≤100 weeks) or a drug–drug interaction (DDI) study of nintedanib and oral contraceptive (in which female patients received nintedanib for ≤28 days). Among patients with lcSSc, we analysed changes from baseline in FVC and adverse events over 52 weeks of SENSCIS-ON in patients who received nintedanib in SENSCIS and continued it in SENSCIS-ON (“continued nintedanib” group) and in patients who received placebo in SENSCIS and initiated nintedanib in SENSCIS-ON or who received nintedanib for a short time in the DDI study (“initiated nintedanib” group). Analyses were descriptive.

Results

There were 98 patients with lcSSc in the continued nintedanib group and 127 patients with lcSSc (114 from SENSCIS, 13 from the DDI study) in the initiated nintedanib group. In these groups, respectively, mean (SD) FVC values at inclusion in SENSCIS-ON were 2449 (662) mL and 72.7(16.7) % predicted and 2508 (771) mL and 74.1 (17.4) % predicted. Mean (SE) changes in FVC from baseline to week 52 of SENSCIS-ON were −45.1 (19.1) mL in the continued nintedanib group, −41.5 (24.0) mL in the initiated nintedanib group, and −43.3 (15.3) mL in all patients with lcSSc, similar to the change in FVC in patients with lcSSc at week 52 of the SENSCIS trial (−39.1 [22.2] mL). The adverse event profile of nintedanib in SENSCIS-ON was consistent with that reported over 52 weeks of the SENSCIS trial (Table 1). Over 52 weeks, adverse events led to discontinuation of nintedanib in 3.1% of patients with lcSSc who continued nintedanib in SENSCIS-ON and 16.5% who initiated nintedanib in SENSCIS-ON.

Adverse events were coded according to preferred terms in the Medical Dictionary for Regulatory Activities.

Conclusion

The change in FVC in patients with lcSSc and ILD who received nintedanib over 52 weeks, and the safety profile of nintedanib, in SENSCIS-ON were similar to that observed in patients with lcSSc and ILD who received nintedanib in SENSCIS. These analyses support a continued effect of nintedanib on slowing decline in FVC and the ability to manage adverse events of nintedanib in patients with lcSSc and ILD over the longer term.

POS0854 BASELINE CHARACTERISTICS OF PATIENTS WITH IMPROVEMENT OR PROGRESSION OF SYSTEMIC SCLEROSIS-ASSOCIATED INTERSTITIAL LUNG DISEASE (SSc-ILD) DURING THE SENSCIS TRIAL

Background

The course of SSc-ILD is variable, and may include periods of stability or even improvement in forced vital capacity (FVC) as well as periods of decline.

Objectives

To investigate the baseline characteristics of patients with SSc-ILD in the placebo group of the SENSCIS trial whose ILD improved or progressed over 52 weeks.

Methods

The SENSCIS trial enrolled patients with SSc with first non-Raynaud symptom in the prior ≤7 years, extent of fibrotic ILD on high-resolution computed tomography (HRCT) ≥10% and FVC ≥40% predicted. Patients who had been taking a stable dose of mycophenolate for ≥6 months were allowed to participate. We investigated the baseline characteristics of patients in the placebo group whose ILD showed improvement (absolute increase in FVC ≥5% predicted), stability (absolute decline or increase in FVC <5% predicted), progression (absolute decline in FVC ≥5% predicted), or significant progression (absolute decline in FVC ≥10% predicted) over 52 weeks. P-values based on ANOVA or Chi-squared tests were used to compare the baseline characteristics of the patients who showed improvement, stability and progression.

Results

Of 288 patients, 21 (7.3%) showed improvement, 166 (57.6%) stability, and 101 (35.1%) ILD progression, of whom 37 (12.8% of all patients) had significant ILD progression over 52 weeks. Most baseline characteristics were similar across the groups based on progression, but there were differences in DLCO % predicted (p=0.02) and in the proportion of patients taking mycophenolate (p=0.09) among patients who showed improvement, stability and progression (Table 1).

Data are mean ± SD or % at baseline. Missing data were excluded. *Assessed visually in whole lung to nearest 5%. The assessment did not include pure (non-fibrotic) ground glass opacities.

Conclusion

These findings suggest that in the SENSCIS trial, patients who had higher DLCO % predicted or who were taking mycophenolate at baseline were less likely to show progression of SSc-ILD over 52 weeks.

OP0157 EFFECT OF NINTEDANIB IN PATIENTS WITH SYSTEMIC SCLEROSIS-ASSOCIATED INTERSTITIAL LUNG DISEASE (SSc-ILD) AND RISK FACTORS FOR RAPID DECLINE IN FORCED VITAL CAPACITY: FURTHER ANALYSES OF THE SENSCIS TRIAL

Background

In the SENSCIS trial conducted in a population of subjects with SSc-ILD with a mean time since first non-Raynaud symptom of 3.5 years and 52% with diffuse cutaneous SSc (dcSSc), nintedanib reduced the rate of decline in FVC (mL/year) over 52 weeks by 44% versus placebo. Risk factors for a rapid decline in FVC in patients with SSc include early SSc, elevated inflammatory markers, significant skin involvement, and dcSSc. Patients with SSc with these risk factors for rapid progression of ILD are typically given immunosuppressants but not nintedanib.

Objectives

To analyse the rate of decline in FVC and the effect of nintedanib on FVC decline in subjects with risk factors for a rapid decline in FVC in the SENSCIS trial.

Methods

In post-hoc analyses of data from the SENSCIS trial, we analysed the rate of decline in FVC (mL/year) over 52 weeks in all subjects and in those with early SSc (<18 months since first non-Raynaud symptom), elevated inflammatory markers (C-reactive protein ≥6 mg/L and/or platelets ≥330 x 109/L), or significant skin fibrosis using two approaches (modified Rodnan skin score [mRSS] 15-40 or mRSS >18) at baseline. We also analysed the rate of decline in FVC over 52 weeks in subjects with one of these risk factors and dcSSc.

Results

Of 575 subjects analysed, 79 (13.7%) had <18 months since first non-Raynaud symptom, 210 (36.5%) had elevated inflammatory markers, 172 (29.9%) had mRSS 15-40 and 118 (20.5%) had mRSS >18. Of 299 subjects with dcSSc, 29 (9.7%) had <18 months since onset of first non-Raynaud symptom, 129 (43.1%) had elevated inflammatory markers, 162 (54.2%) had mRSS 15-40 and 118 (39.5%) had mRSS >18. In the placebo group, the rate of decline in FVC over 52 weeks was numerically greater in subjects with these risk factors for rapid decline in FVC compared with all subjects (Figure 1). Across the subgroups, the rate of decline in FVC was numerically lower in subjects treated with nintedanib than placebo (Figure 1).

Figure 1.

Rate of decline in FVC (mL/year) over 52 weeks in (A) all patients and in patients with risk factors for rapid decline in FVC at baseline and (B) all patients and in patients with dcSSc and risk factors for rapid decline in FVC at baseline in the SENSCIS trial.

Conclusion

The SENSCIS trial included a broad range of subjects with a fibrotic ILD complicating SSc, including those with risk factors for a rapid decline in FVC. In the placebo group, subjects with these risk factors had a more rapid decline in FVC over 52 weeks compared with the overall trial population. By targeting fibrosis with nintedanib, the rate of decline in FVC in patients with risk factors for FVC decline was reduced in patients treated with nintedanib compared with placebo.

Association of sarcopenia and oxygen uptake efficiency slope in male patients with heart failure: The skeletal muscle hypothesis in practice

Funding Acknowledgements

Type of funding sources: Foundation. Main funding source(s): Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Background

Sarcopenia, a generalized loss of muscle mass and function, is a common comorbidity in patients with heart failure (HF). The skeletal muscle, through afferent nerve pathways, modulates the respiratory response during physical efforts. However, whether ventilatory behavior is affected by the presence of sarcopenia is still unknown.

Purpose

To evaluate the impact of sarcopenia in ventilatory parameters of patients with HF.

Methods

We enrolled 169 male patients with stable chronic HF with left ventricular ejection fraction &lt;40% (LVEF). Muscle strength was measured by handgrip dynamometer. Body composition was measured with dual-energy X-ray absorptiometry (DXA). Appendicular skeletal muscle (ASM) was comprised by lean muscle mass of both arms and legs. Sarcopenia was defined by handgrip strength and ASM/height2 lower than 27 kg and 7.0 kg/m2, respectively. Ventilation (VE), oxygen consumption (VO2), and carbon dioxide output (VCO2) were evaluated using breath-by-breath measurements during a cardiopulmonary exercise test performed on a cycle ergometer. Oxygen uptake efficiency slope (OUES) was calculated from data taken at exercise peak.

Results

Sarcopenia was identified in 29 patients (17.2%). Patients with sarcopenia had lower body mass index (BMI; 21.2±2.4 vs. 26.5±3.8 kg/m2, p&lt;0.0001) with higher C-reactive protein [CRP; 12.4 (2.8-22.4) vs. 2.4 (1.0-6.3) mg/L, p&lt;0.001] and brain natriuretic peptide [BNP; 949 (446-1722) vs. 374 (127-885) pg/mL, p&lt;0.001] compared to patients without sarcopenia, respectively. At the first ventilatory threshold, VE/VO2 (36.9±5.9 vs. 32.7±6.5, p=0.003) and VE/VCO2 (39.8±7.2 vs. 35.3±6.9, p=0.004) were higher in sarcopenic patients compared to those without sarcopenia. At the exercise peak, comparing to patients without sarcopenia, sarcopenic patients had lower OUES (1,186±295 vs. 1,634±564, p&lt;0.001), absolute VO2 (0.93±0.25 vs. 1.43±0.47 L/min, p&lt;0.0001), relative VO2 (16.2±5.0 vs. 19.5±6.5 ml/kg/min, p=0.011), and VE (47.3±10.1 vs. 63.0±18.2 L/min, p&lt;0.001), while VE/VCO2 (42.9±8.9 vs. 38.7±8.4, p=0.025) was increased and VE/VO2 (49.6±11.5 vs. 45.1±10.8, p=0.066) showed a tendency to be higher. OUES was positively correlated with total lean body mass (r=0.38; p&lt;0.0001), ASM/height2 (r=0.36; p&lt;0.0001), and handgrip strength (r=0.31; p&lt;0.001). In a multivariate logistic regression model using OUES as the dependent variable, ASM/height2 (OR, 1.466; 95% CI, 1.003–2.141; p=0.048), haemoglobin (OR, 0.346; 95% CI, 0.135–0.886; p=0.027), and creatinine (OR, 0.391; 95% CI, 0.166–0.918; p=0.031) were independently associated with OUES adjusted by age, BMI, LVEF, BNP, CRP, and beta-blocker use.

Conclusion

Our results suggest that sarcopenia, possibly by reducing thoracic skeletal muscle mass or inefficiently modulating ventilation through afferent pathways, is related to impaired ventilatory response during exercise in patients with HF.

Coronary microvascular dysfunction in hypertrophic cardiomyopathy – impact from tissue characteristics to clinical manifestations

Background

Coronary microvascular dysfunction (CMD) is an important pathophysiological feature in hypertrophic cardiomyopathy (HCM).

Purpose

This study investigated the role of CMD in tissue characteristics, left ventricular (LV) systolic performance and clinical manifestations in HCM.

Methods

This prospective study enrolled patients with HCM without obstructive epicardial coronary artery disease. Each patient underwent cardiovascular magnetic resonance (CMR) including parametric mapping, perfusion imaging during regadenoson-induced hyperemia, late gadolinium enhancement (LGE) and three-dimensional longitudinal, circumferential and radial strains analysis. Electrocardiogram and 24 hours Holter recording were performed to assess arrhythmias.

Results

75P were enrolled, 47 (63%) males, mean age 54.6 (14.8) years; 51 patients (68%) had non obstructive HCM, mean maximum wall thickness (MWT) was 20.2 (4.6)mm, LV ejection fraction 71.6 (8.3)%, ischemic burden 22.5 (16.9)% of LV.

Greater MWT was associated the severity of ischemia (β-estimate: 1.809, 95% CI: 1.073; 2.545; p&lt;0.001).

Ischemic burden was strongly associated with higher values of native T1 (β-estimate: 9.018, 95% CI: 4.721, 13.315; p&lt;0.001).

An association between ischemia and the extent of LGE was found (β-estimate: 2.02, 95% CI: 0.93, 3.10; p&lt;0.001). Ischemia in ≥21% of LV was associated with LGE &gt;15% (AUC 0.766, sensitivity 0.724, specificity 0.659).

In multivariable analysis, in the overall population, MWT and LGE were independently associated with ischemia, however the evidence of association between ischemia and extent of LGE became weaker (β-estimate: 1.070, 95% CI: −0.106; 2.245; p=0.074).

In subgroup analysis, the association between ischemia and LGE remained significant in individuals with MWT 15–20mm, non-obstructive HCM, female and age &lt;40 years.

The severity of ischemia was not associated with markers of LV systolic function, namely LVEF, longitudinal, radial and circumferential strain

A strong evidence of association was found between ischemia and atrial fibrillation/flutter (AF/AFL) (OR: 1.481, 95% CI: 1.020,2.152; p=0.039), but no association was verified with non-sustained ventricular tachycardia.

Conclusion

In HCM, CMD is related to the severity of LV hypertrophy. Ischemia secondary to CMD promotes fibrosis and is associated with an increase in the odds of AF/ALF.

P–569 Woman with CYP19A1 TC/CC genotype have increased susceptibility to infertility development, independently of the cause

Study question

Is TC/CC genotype of codon 39 at CYP19A1 gene associated with the development of female infertility?

Summary answer

Yes, CYP19A1 codon 39 TC/CC genotype is associated with increased susceptibility to infertility development in women, regardless of associated cause.

What is known already

Aromatase protein is responsible for the aromatization of androgens into estrogens. This protein that catalyzes the final step in biosynthesis of estrogens is encoded by the gene CYP19A1. The CYP19A1 gene is located on chromosome 15q21.1. It is a member of the cytochrome P450 superfamily which are monooxygenases that catalyze many reactions involved in steroidogenesis. TC/CC genotype of codon 39 at CYP19A1 gene results in an increase of aromatase activity and thus affect the hormone levels which can lead to the development of various diseases, including infertility.

Study design, size, duration

A case-control study was designed to investigate the association of CYP19A1 gene polymorphism with female infertility. Case subjects, 201 women with infertility established as women under 39 years of age, that failed to establish a clinical pregnancy after 12 months of regular, unprotected sexual intercourse. 161 fertile female controls, with no previous history of infertility, no previous history of gynecological pathologies compatible with infertility, and no history of IVF treatments, were selected.

Participants/materials, setting, methods

Blood was collected by venous puncture and genomic DNA was extracted. CYP19A1 genotyping was performed by polymerase chain reaction-based methods with confronting two-pair primers. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated by unconditional logistic regression.

Main results and the role of chance

Significant statistical association of the TC/CC genotype combined with endometriosis risk was found, with reference to TT genotype (OR 4.554; 95% CI 2.209–9.386; p &lt; 0.001). We also found an increased risk of developing polycystic ovary syndrome (PCOS) associated with TC/CC genotype (OR 5.317; 95% CI 2.767–10.215; p &lt; 0.001). We also observed an increased prevalence of premature ovarian failure associated with TC/CC genotype (OR 3.376; 95% CI 1.672–6.815; p = 0.001) and verified an increased prevalence of tubal pathology in carriers of TC/CC genotype (OR 3.231; 95% CI 1.653–6.314; p = 0.001). Finally, a strong association of TC/CC genotype with female infertility, regardless of the cause was found (OR 4.232; 95% CI 2.710–6.609; p &lt; 0.001). In conclusion, TC/CC genotype is associated with increased susceptibility to infertility development in women.

Limitations, reasons for caution

The sample size may eventually be considered small, despite the strong significance found.

Wider implications of the findings: There are not many studies in this area and the few existing exhibit disparate results. The association of TC/CC genotype with endometriosis was observed in a few studies, but some disagree. This difference could be attributed to the notable heterogeneity across the different studies.

Cystlike Lesions as a Late Sequela of Radiotherapy in Pediatric Patients

BACKGROUND AND PURPOSE

The developing nervous system is particularly vulnerable to late adverse effects of cranial radiation therapy, such as leukoencephalopathy, microbleeds, and cavernomas. Cystlike lesions have been rarely described and characterized in the literature. We aimed to characterize cystlike lesions, their risk factors, and association with other late adverse effects.

MATERIALS AND METHODS

Children treated for brain tumors during a 30-year period (n = 139) were included. We documented imaging findings, focusing on cystlike lesion development and its relationship with clinical history and other imaging findings. Multivariable analysis was performed using logistic regression and negative binomial regression models.

RESULTS

Cystlike lesions developed in 16.5% of patients treated with radiotherapy, with a median of 2 years until the development of the first lesion. For every 4-year age increase, there were 50% decreased odds of developing lesions and a 50% decrease in the average count of lesions. Females demonstrated a 4.00 rate ratio of developing a higher number of lesions. Patients who underwent chemoradiotherapy had 3.20 increased odds of developing cystlike lesions compared with patients with radiation therapy alone. A larger proportion of patients treated with methotrexate (25%) developed cystlike lesions, but this was not statistically significant. Cystlike lesions tended to develop in cerebral locations where leukoencephalopathy was worse. A strong relationship was found between the development of cystlike lesions and leukoencephalopathy severity.

CONCLUSIONS

Cystlike lesions are frequent and under-reported late adverse effects of cranial radiation therapy in children. Younger age, chemoradiotherapy, and the severity of leukoencephalopathy represent risk factors for the development of cystlike lesions.

POS0840 RISK OF MALNUTRITION IN PATIENTS WITH SYSTEMIC SCLEROSIS-ASSOCIATED INTERSTITIAL LUNG DISEASE (SSC-ILD): FURTHER ANALYSES OF THE SENSCIS TRIAL

Background:

Gastrointestinal (GI) involvement is common in patients with SSc and may lead to weight loss and malnutrition. In the SENSCIS trial in patients with SSc-ILD, nintedanib reduced the rate of decline in forced vital capacity (FVC) (mL/year) over 52 weeks, with mainly GI adverse events. The Malnutrition Universal Screening Tool (MUST) was developed to identify adults who are at risk of malnutrition and has been used in studies of patients with SSc.

Objectives:

To evaluate nutritional status over 52 weeks in the SENSCIS trial based on a modified MUST score.

Methods:

The SENSCIS trial enrolled patients with SSc-ILD with first non-Raynaud symptom ≤7 years before screening, extent of fibrotic ILD ≥10% on HRCT and FVC ≥40% predicted. Patients who had taken a stable dose of mycophenolate for ≥6 months were eligible to participate. Patients were randomised to receive nintedanib 150 mg bid or placebo. Dose reductions to 100 mg bid and treatment interruptions were allowed to manage adverse events and specific recommendations were provided for the management of diarrhoea. We calculated a modified MUST score at baseline and weeks 12, 24, 36 and 52 based on (A) BMI, (B) weight loss (week 12 vs baseline; week 24 vs week 12; week 36 vs week 24; week 52 vs week 36), and (C) a surrogate for acute disease effect (if the patient had any serious adverse event that led to hospitalisation between weight assessments and received ≥1 medication from the WHO classification code for “solutions for parenteral nutrition” for ≥5 days). MUST score at baseline was based solely on BMI. With scores ranging from 0 to 6, the risk of malnutrition is defined as low (score = 0), medium (score = 1) or high (score ≥2).

Results:

Among 576 patients who received nintedanib (n=288) or placebo (n=288), mean (SD) age at baseline was 54.0 (12.2) years, weight was 69.7 (15.9) kg and BMI was 25.9 (5.0) kg/m2; median time since onset of first non-Raynaud symptom was 3.4 years; and 75.2% of patients were female. In the nintedanib and placebo groups, respectively, MUST scores suggested that 74.0% and 78.1% of patients were at low risk of malnutrition at baseline and remained at low risk at their last measurement (Table 1). At weeks 12 and 52, respectively, mean (SD) MUST scores were 0.3 (0.6) and 0.4 (0.7) in the nintedanib group and 0.2 (0.5) and 0.2 (0.6) in the placebo group. At weeks 12, 24, 36 and 52, respectively, the proportions of patients at low risk of malnutrition were 81.8%, 80.9%, 72.9% and 76.5% in the nintedanib group and 86.6%, 86.4%, 88.3% and 80.8% in the placebo group; the proportions at medium risk were 12.1%, 13.1%, 18.0% and 13.5% in the nintedanib group and 8.5%, 8.6%, 5.8% and 13.1% in the placebo group; and the proportions of patients at high risk were 6.1%, 5.6%, 8.3% and 9.6% in the nintedanib group and 4.9%, 4.3%, 4.7% and 5.4% in the placebo group.

MUST score ranges from 0 to 6. Score of 0 = low risk: score of 1 = medium risk; score of ≥2 = high risk. Baseline MUST score was based solely on BMI.

Conclusion:

In the SENSCIS trial, scores based on a modified MUST indicated that most patients treated with nintedanib were at low risk of malnutrition at baseline and remained at low risk over 52 weeks. The proportions of patients at high risk of malnutrition were low but were numerically greater in patients who received nintedanib than placebo. Management of disease manifestations and gastrointestinal adverse events that may be associated with weight loss is important to reduce the risk of malnutrition in patients with SSc-ILD treated with nintedanib.

OP0266 EFFICACY OF NINTEDANIB IN PATIENTS WITH SYSTEMIC SCLEROSIS-ASSOCIATED INTERSTITIAL LUNG DISEASE (SSC-ILD) AND INTERNAL ORGAN INVOLVEMENT: DATA FROM THE SENSCIS TRIAL

Background:

SSc is a heterogeneous autoimmune disease characterised by fibrosis of the skin and internal organs. In most patients with SSc-ILD, organs other than the lungs are also affected. In the SENSCIS trial in patients with SSc-ILD, nintedanib reduced the rate of decline in forced vital capacity (FVC) (mL/year) over 52 weeks by 44% versus placebo.

Objectives:

We investigated the extent of organ involvement related to SSc at baseline in patients in the SENSCIS trial and the effect of nintedanib versus placebo on the rate of FVC decline in subgroups by internal organ involvement.

Methods:

The SENSCIS trial enrolled patients with SSc-ILD with first non-Raynaud symptom ≤7 years before screening, extent of fibrotic ILD ≥10% on high-resolution computed tomography (HRCT) and FVC ≥40% predicted. Patients with clinically significant pulmonary hypertension were excluded. Patients were randomised to receive nintedanib or placebo until the last patient reached week 52 but for ≤100 weeks. In post-hoc analyses, we analysed the rate of decline in FVC (mL/year) over 52 weeks in subgroups with and without different types of SSc-related internal organ involvement (upper gastrointestinal; lower gastrointestinal; cardiovascular [CV]; peripheral vascular; muscular; joint). These subgroups were defined based on patients’ SSc-related medical history as reported in the case report form. A random slope and intercept model was used to assess the rate of decline in FVC (mL/year) and an interaction test applied to assess potential heterogeneity in the treatment effect of nintedanib between the subgroups.

Results:

Of 576 patients, 96.9% had peripheral vascular involvement, 75.5% had upper gastrointestinal and 39.8% lower gastrointestinal involvement, 45.7% had CV involvement, 40.6% had joint involvement, and 27.1% had muscular involvement at baseline. In the placebo group, the rate of decline in FVC (mL/year) was numerically greater in patients with than without upper gastrointestinal involvement and in patients without than with joint involvement or muscular involvement (Figure). The exploratory interaction p-values did not indicate heterogeneity in the treatment effect of nintedanib versus placebo on reducing the rate of decline in FVC (mL/year) between the subgroups based on organ involvement (p>0.05 for all treatment-by-time-by-subgroup interactions) (Figure).

Conclusion:

Patients in the SENSCIS trial had diverse complications related to SSc. There was no evidence of a differential treatment effect of nintedanib on reducing the rate of decline in FVC based on gastrointestinal, CV, joint, or muscular involvement at baseline.

POS0835 DECLINE IN FORCED VITAL CAPACITY (FVC) IN SUBJECTS WITH SYSTEMIC SCLEROSIS-ASSOCIATED INTERSTITIAL LUNG DISEASE (SSC-ILD) IN THE SENSCIS TRIAL VERSUS HYPOTHETICAL REFERENCE SUBJECTS WITHOUT LUNG DISEASE

Background:

In the randomized SENSCIS trial in subjects with SSc-ILD, nintedanib reduced the rate of decline in FVC over 52 weeks (mL/year) by 44% compared to placebo. Healthy individuals have varied FVC depending on age, sex, ethnicity and height; expected values can be determined using internationally recognised reference equations.

Objectives:

To provide further context to the FVC declines observed in the SENSCIS trial, we compared the decline in FVC observed in subjects with SSc-ILD in the SENSCIS trial with the decline in FVC that would be expected in hypothetical subjects without ILD matched for age, sex, ethnicity and height.

Methods:

The SENSCIS trial enrolled subjects with SSc-ILD aged ≥18 years with first non-Raynaud symptom ≤7 years before screening, extent of fibrotic ILD ≥10% on HRCT, FVC ≥40% predicted and DLco 30–89% predicted. Baseline FVC (mL) and changes in FVC (mL) at week 52 were assessed in the nintedanib and placebo groups, with missing values at week 52 imputed using predictions from the primary analysis model (random slope and intercept model). Changes in FVC in the SENSCIS trial were compared to values in hypothetical healthy reference subjects matched to the SENSCIS subjects for age, sex, ethnicity and height. FVC values in these healthy reference subjects were derived from the equations published by the European Respiratory Society Global Lung Function Initiative in 2012, which were derived from data from over 70,000 subjects.1

Results:

In the nintedanib and placebo groups of the SENSCIS trial, respectively, mean (SD) time since onset of first non-Raynaud symptom was 3.5 (1.6) and 3.5 (1.8) years. In the nintedanib group, mean (SD) FVC at baseline was 2460 (737) mL, compared with 3403 (787) mL in the healthy reference subjects. In the placebo group, mean (SD) FVC at baseline was 2544 (817) mL compared with 3516 (887) mL in the healthy reference subjects. The difference in the change from baseline in FVC at week 52 between the nintedanib-treated subjects in the SENSCIS trial (n=287) and the healthy reference subjects was 26.6 mL ([95% CI: 1.2, 52.0]; p=0.04). The difference in the change from baseline in FVC at week 52 between the placebo-treated subjects in the SENSCIS trial (n=286) and the reference subjects was 77.5 mL ([95% CI: 51.4, 103.7]; p<0.001) (Figure 1).

Conclusion:

Subjects with SSc-ILD who participated in the SENSCIS trial had marked lung function impairment at baseline compared with healthy matched reference subjects, despite a mean duration of SSc of 3.5 years. Over 52 weeks, the decline in FVC in subjects with SSc-ILD who received placebo was 4-fold greater than in healthy reference subjects. Subjects with SSc-ILD who were treated with nintedanib had a decline in FVC that was only slightly greater than the decline observed in the matched healthy subjects. These data support the clinical relevance of the reduction in the rate of FVC decline provided by nintedanib in patients with SSc-ILD.

OP0170 DECLINE IN FORCED VITAL CAPACITY (FVC) IN PATIENTS WITH SYSTEMIC SCLEROSIS-ASSOCIATED INTERSTITIAL LUNG DISEASE (SSC-ILD) WITH AND WITHOUT DYSPNOEA: DATA FROM THE SENSCIS TRIAL

Background:

Some patients with SSc-ILD develop dyspnoea secondary to parenchymal lung disease, while others do not report dyspnoea even when their lung function is impaired. It is unclear whether the presence of dyspnoea is associated with a worse course of SSc-ILD or with response to therapy.

Objectives:

To investigate the rate of decline in FVC in patients with SSc-ILD in the SENSCIS trial in subgroups by patient-reported dyspnoea at baseline.

Methods:

The SENSCIS trial enrolled patients with SSc-ILD with first non-Raynaud symptom within ≤7 years before screening, extent of fibrotic ILD ≥10% on HRCT and FVC ≥40% predicted. Patients were randomised to receive nintedanib or placebo until the last patient reached week 52. In post-hoc analyses, we analysed the rate of decline in FVC (mL/year) over 52 weeks in patients with and without dyspnoea at baseline based on the question about dyspnoea in the St. George’s Respiratory Questionnaire (SGRQ). Patients who reported having shortness of breath “most days a week”, “several days a week” or “a few days a month” (rather than “only with chest infection” or “not at all”) over the last month were considered to have dyspnoea at baseline. A random slope and intercept model was used to assess the rate of decline in FVC (mL/year) and an interaction test was applied to assess potential heterogeneity in the treatment effect of nintedanib between the subgroups.

Results:

Of 576 patients, 69.8% had dyspnoea at baseline. At baseline, in patients with and without dyspnoea, respectively, mean (SD) extent of fibrotic ILD on HRCT was 37.7 (21.7)% and 31.6 (19.4)%; mean (SD) FVC was 71.0 (16.3) and 76.5 (16.8) % predicted; 50.7% and 44.8% were taking mycophenolate; 53.5% and 41.9% were taking corticosteroids. In the placebo group, the rate of decline in FVC (mL/year) was similar in patients with and without dyspnoea at baseline (Figure). The effect of nintedanib versus placebo on reducing the rate of decline in FVC (mL/year) was numerically more pronounced in patients without dyspnoea (difference: 79.8 [95% CI: 9.8, 149.7]) than with dyspnoea (difference: 25.7 [-19.9, 71.3]), but the exploratory interaction p-value did not indicate heterogeneity in the treatment effect between subgroups (p=0.20).

Conclusion:

In the SENSCIS trial, patients with SSc-ILD who had dyspnoea at baseline had a numerically greater extent of fibrotic ILD on HRCT and numerically lower FVC % predicted at baseline. The rate of decline in FVC in the placebo group was similar in patients with and without dyspnoea. Nintedanib had a numerically greater treatment effect in patients without dyspnoea. These data suggest that the presence of dyspnoea should not be used as a criterion for starting nintedanib in patients with SSc-ILD.

AB0431 EXPLORING THE UTILITY OF THE AMERICAN COLLEGE OF RHEUMATOLOGY (ACR) CRISS IN PATIENTS WITH DIFFUSE CUTANEOUS SYSTEMIC SCLEROSIS

Background:

The ACR Composite Response Index in diffuse cutaneous Systemic Sclerosis (CRISS) was developed to measure the probability of improvement in response to treatment in patients with early diffuse cutaneous SSc (dcSSc), accounting for new/worsening cardiopulmonary involvement and/or renal crisis, and changes in modified Rodnan skin score, forced vital capacity, health assessment questionnaire disability index, and patient’s and physician’s global impressions. In patients with SSc-ILD, treatment response may be reflected as slower progression, stabilisation or improvement.

Objectives:

Using data from patients with dcSSc and ILD in the placebo group of the SENSCIS trial, we analysed the probability of improvement using the ACR CRISS score at week 52. We also evaluated whether the CRISS numerator could provide information on the spectrum of responses in this patient population.

Methods:

The SENSCIS trial enrolled subjects with SSc-ILD with onset of first non-Raynaud symptom ≤7 years before screening, FVC ≥40% predicted, and fibrotic ILD ≥10% extent on an HRCT scan. Subjects on prednisone ≤10 mg/day (or equivalent) and/or stable therapy with mycophenolate or methotrexate were allowed to participate. Subjects were randomised to receive nintedanib or placebo. Subjects were not randomised by use of mycophenolate. In patients randomised to receive placebo who had dcSSc and/or mRSS >15 at baseline, we analysed the ACR CRISS and its numerator at week 52 in subgroups by use of mycophenolate at baseline. Analyses were exploratory and descriptive.

Results:

Of 117 analysed subjects in the placebo group who had dcSSc and/or mRSS >15 at baseline, 60 (51.3%) were taking mycophenolate at baseline. Compared with patients not taking mycophenolate at baseline, those taking mycophenolate had a lower mean age (48.4 [SD 11.8] vs 53.1 [13.4] years), lower mean FVC % predicted (68.8 [17.0] vs 73.0 [14.6]), and a greater proportion were female (76.7% vs 71.9%); median time since first onset of non-Raynaud symptom was similar (3.9 vs 4.5 years, respectively) as was mean (SD) mRSS (16.5 [7.7] vs 15.9 [8.0], respectively). One patient (taking mycophenolate at baseline) had limited cutaneous SSc. At week 52, median (Q1, Q3) ACR CRISS score was 0.036 (0.001, 0.601) in subjects taking mycophenolate and 0.002 (0.000, 0.112) in subjects not taking mycophenolate at baseline, and mean (SD) ACR CRISS score was 0.28 (0.37) in subjects taking mycophenolate and 0.16 (0.31) in subjects not taking mycophenolate at baseline (Figure 1). In these groups, respectively, 25.0% and 14.0% of subjects had CRISS score >0.6 (considered improved) at week 52. The CRISS numerator provided a broader distribution of response values, but was not informative in this patient population.

Conclusion:

In exploratory analyses, among subjects with dcSSc and ILD who received placebo in the SENSCIS trial, the proportion considered improved at week 52 based on ACR CRISS score was numerically greater in patients taking than not taking mycophenolate at baseline. There remains a need for composite scores that provide better interpretation of the magnitude of response in patients with SSc.

POS0855 PATIENT PREFERENCES, TRADE-OFFS AND ACCEPTABLE RISKS IN THE TREATMENT OF SYSTEMIC SCLEROSIS-ASSOCIATED INTERSTITIAL LUNG DISEASE: A STEP TOWARDS SHARED DECISION-MAKING

Background:

Current treatments for systemic sclerosis-associated interstitial lung disease (SSc-ILD) are characterised by different attributes such as mode of administration, adverse events (AE) and efficacy. Physicians and patients often have different perspectives on treatments, thus shared decision-making between patients and physicians is essential. An understanding of patients’ decision processes when weighing treatment attributes and the trade-offs they are willing to make is important for shared decision-making.

Objectives:

The study aimed to 1) identify relevant treatment attributes, 2) elicit patient preferences for these attributes and 3) quantify preference as relative attribute importance (RAI; a higher RAI indicates that more of the variability in patients’ responses may be explained by changes in the attribute); and maximum acceptable risk (MAR) of diarrhoea, nausea and/or vomiting (MAR is a trade-off measure that evaluates attributes in risk-equivalences as a unit of measurement).

Methods:

A discrete choice experiment (DCE) was created, based on a literature review, a patient advisory board, qualitative patient interviews, and a workshop involving SSc-ILD expert physicians. Seven SSc-ILD treatment attributes were identified: 1) mode of administration; 2) shortness of breath; 3) skin tightness; 4) cough; 5) tiredness; 6) risk of gastrointestinal tract (GIT) AEs; and 7) risk of serious and non-serious infections. The levels of AE risk were informed by frequencies observed in clinical trials and patient input during the interviews. The DCE was integrated into an online survey, which asked patients to make repeated choices between two alternatives described by varying levels of included attributes. Patients with SSc-ILD were recruited by physician referral from Switzerland, Norway, France, Germany and the USA. DCE data were analysed using a logit model, and RAI and MAR measures were calculated.

Results:

A total of 231 patients with physician-confirmed SSc-ILD (mean age 52.6±13.2 years; 54% diagnosed for >5 years) completed the survey. Patients with SSc-ILD mostly preferred twice-daily oral treatments (p<0.001) and infusion every 6–12 months (p<0.001) over monthly infusions. Patients’ choices were mostly affected by the risk of GIT AEs (RAI=25%; 95% CI 22–28%) and risk of infections (RAI=20%; 95% CI 16–24%). Improvements in shortness of breath and type and severity of cough were jointly more important than improvement in skin tightness (p<0.001).

Patients accepted an additional 21% risk (95% CI 13–29%) of GIT AEs if they could reduce the frequency of infusions from monthly to 6–12 monthly, or accepted an extra 15% (95% CI 7–23%) increase in risk if changing to an oral treatment twice daily. Among symptoms, an additional 28% (95% CI 20–36%) risk of GIT AEs was considered acceptable if the severity of patients’ persistent cough was reduced to a level that was easier to tolerate, even if it remained persistent. Similarly, a 37% (95% CI 28–46%) increase in the risk of GIT AEs was acceptable if it resulted in breathlessness during routine activities rather than breathlessness at rest. Finally, patients were willing to accept an additional 36% risk (95% CI 27–45%) of GIT AEs if it reduced their risk of non-serious infections from 30% to 15% and of serious infections from 10% to 5%.

Conclusion:

This is the first study to quantitatively elicit patients’ preferences for attributes of SSc-ILD treatments. Preferences were driven by safety, efficacy and technical considerations. Patients showed willingness to make trade-offs, providing a firm basis for shared decision-making in routine clinical practice.

POS0316 MODELLING SHORT-TERM FVC CHANGES FROM SENSCIS TO LONG-TERM FVC COURSE IN SSc-ILD DEMONSTRATES CLINICALLY MEANINGFUL REDUCTION OF FVC DECLINE AND SURVIVAL BENEFITS

Background:

Nintedanib has shown to slow FVC decline by 41ml over 52 weeks in systemic sclerosis-associated interstitial lung disease (SSc-ILD). However, the long-term effect of nintedanib treatment on ILD progression and mortality in SSc patients is so far unknown.

Objectives:

Here, the 52-week treatment efficacy of nintedanib was modeled and extrapolated on the long-term FVC course and survival in SSc-ILD patients from the European Scleroderma Trial and Research (EUSTAR) database.

Methods:

SSc patients from the EUSTAR database fulfilling the inclusion criteria of the SENSCIS trial (SSc classification criteria, ILD confirmed by imaging, disease duration of <7 years, FVC≥40%pred, diffusion capacity of the lung for carbon monoxide (DLCO) 30-89%pred); and matched for baseline characteristics as well as matched for the 52-week FVC change of SENSCIS patients were included (n=236). Linear mixed models including time, risk factors at baseline (sex, age, dyspnea class, DLCO%, CRP, modified Rodnan skin score, SSc subtype, SSc auto-antibodies, disease duration, synovitis and muscle weakness) were used to estimate the natural FVC course over time. On this natural course of FVC, the observed effect from the SENSCIS trial representing the absolute 52-week difference of FVC decline between the nintedanib and the placebo group was applied as continuous annual effect (SENSCIS effect model). Survival was estimated for both the natural course as well as the SENSCIS effect model using Cox regression.

Results:

Of the 236 included patients, 75% were females, 65% had diffuse cutaneous SSc. Mean age was 50.6 years, mean FVC 78.2%pred and DLCO 56.3%pred at time of inclusion. Mean FVC change after 12±3 months was -2.3 ±6.9%pred. These parameters were largely similar to the characteristics of the SENSCIS population.

In the longitudinal follow up of this population, the natural course of FVC showed a total FVC decline of -16.3%pred over 5 years. With assumed SENSCIS effects (effects of nintedanib treatment reported in SENSCIS), the 5-year FVC decline was reduced to -10.3%pred (Figure 1).

The reduced FVC progression translated into an improved survival. The natural 5-year survival of this SSc-ILD population was 88.2%. When extrapolating also a severe FVC decline early in the course, frequently terminated by early mortality of SSc patients excluding them from long-term outcome assessment, the estimated 5-year survival was reduced to 81.6%. When the SENSCIS effects on FVC were considered, the 5-year extrapolated survival was increased to 86.3% (Figure 2).

Conclusion:

Long-term experience of nintedanib treatment in SSc-ILD patients is lacking so far, therefore we modeled and extrapolated the 52-week treatment efficacy of nintedanib on the long-term FVC course and survival in SSc-ILD patients from the EUSTAR database. We could demonstrate a significant reduction of FVC decline by extrapolating the annual treatment effects of nintedanib from the SENSCIS trial from 1 to 5 years in EUSTAR. Translating these reductions of FVC decline into survival, the 5-year mortality rate was reduced from 18% to 13%.

Lipid transfer to high-density lipoprotein is greater in elderly individuals with higher predictive cardiorespiratory fitness for age

Funding Acknowledgements

Type of funding sources: Foundation. Main funding source(s): FAPESP and CNPq

Background

Elderly individuals have higher coronary artery disease (CAD) risk. Triggering factors include diminished peak of oxygen consumption (VO2peak), commonly referred as cardiorespiratory fitness (CF), and increase in atherogenic lipid profile: non high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). The effect of aging on HDL-C is yet not clear, however, evaluating only the concentrations do not represent all HDL anti-atherosclerosis potential, aspects related to HDL metabolism and function can be more accurate to understand atherosclerosis process. Beyond that, elderly individuals also show reduced lipid transfer to HDL, an important assessment of HDL metabolism and function reported to be lower in CAD patients. Additionally, higher CF level is associated with longevity and lower hospitalizations rates and higher lipid transfer, independently of HDL-C. Data about different ages and absolute values of CF on lipids transfer are nonexistent. Purpose: To analyze the effect of paired CF absolute values and BMI in a healthy population of different ages on lipid transfer to HDL. Methods: 61 healthy individuals, enrolled in two groups: 30 young (27 ± 4 years, 21 females, BMI: 24.6 ± 2.6 kg/m², VO2peak: 33.9 ± 5.0 ml/kg/min) and 31 elderly (67 ± 5 years, 15 females, BMI: 23.9 ± 3.3 kg/m², VO2peak: 33.2 ± 4.5 ml/kg/min) that do not use any medication for chronic disease. Anthropometric data were collected. All participants performed treadmill cardiopulmonary test and the CF predictive value for age was calculated, according to each sex. Plasma lipids and cholesterol ester transfer protein (CETP) concentrations were determined. Lipid transfer was performed by incubating plasma with a donor lipoprotein-like nanoparticle containing radioactively labeled unesterified cholesterol (UC) and esterified cholesterol (EC), followed by chemical precipitation and radioactive count.  Cholesterol transfers from the donor nanoparticle to HDL are expressed as %. For the statistical analysis Student"s t and Mann-Whitney tests were used according to data distribution. Results: Waist circumference (p = 0.0291) and waist-hip ratio (p &lt; 0.0001) were higher in elderly. LDL-C (p = 0.0005) and non HDL-C (p = 0.0003) were higher in elderly, as well apolipoprotein A-I, B, and CETP concentration. HDL-C and triglycerides were equal between groups. EC (p = 0.0268) and UC (p = 0.0348) transfers to HDL were higher in elderly. VO2peak predictive by age expressed in percentage was higher in elderly (90 ± 13 vs. 120 ±18; p &lt; 0.0001). Conclusion: Elderly individuals show higher anthropometric data and concentrations of atherogenic cholesterol lipoproteins; however, HDL-C was equal. When paired by absolute CF values and BMI with young adults, elderly subjects with high CF predicted by age, have higher cholesterol transfer to HDL which demonstrates greater HDL metabolism.

Estrogens in schizophrenia: What do we know?

Introduction

Schizophrenia is a chronic disease that significantly impacts cognitive functioning. Sex differences in incidence, onset and course of schizophrenia suggest estrogens have a protective role.

Objectives

Our aim is to review the state of the art on this matter.

Methods

Through a selection of the most relevant articles found on PubMed and ClinicalKey searching the keywords: “estrogens” and “schizophrenia”.

Results

Accumulating evidence has led to the hypothesis that estrogens act as a protective factor in women regarding the onset of schizophrenia as their increase in puberty may help delay the onset of symptoms. Also, the estrogens abrupt decline in menopause may account for a second peak of onset and greater severity of the symptoms. During the menstrual cycle, when serum estrogens are at their lowest, there is an increase in the number of psychotic episodes and an exacerbation of psychotic symptoms. Pregnancy leads to an improvement of psychotic symptoms, which then worsen in postpartum. Clinical trials testing the efficacy of estrogens have been promising, which suggest they might be a useful adjuvant treatment. Despite the evidence of clinical efficacy, health risks for women using estrogen therapy should be considered, as they decrease its acceptability as a viable treatment option. The use of selective estrogen receptor modulators (SERMs), as raloxifene, could be a favorable and safer alternative.

Conclusions

In conclusion, estrogens are proving to be a promising option as a complementary therapy for schizophrenia; however, further studies are needed to investigate whether they might be overall beneficial.

N-acetylcysteine can be the key to tackling substance use disorders

Introduction

N-acetylcysteine (NAC) is a precursor of cysteine and glutathione, widely known as an antidote to paracetamol overdose. Its role as precursor of an antioxidant and modulating agent of glutamatergic, dopaminergic, neurotropic and inflammatory pathways, raised interest in its application in psychiatric disorders. NAC emerges as a promising therapeutic agent in substance use disorders (SUD) and provides a treatment option in a field with limited and suboptimal therapies.

Objectives

To describe the use of NAC in SUD (tobacco, cocaine, cannabis, methamphetamine and alcohol), its potential mechanisms and clinical application.

Methods

The literature was searched using the Pubmed database with the following keywords “N-acetylcysteine”, “Substance use disorders” and “Psychiatry”. Retrieved papers (2011-2018) were selected according to their relevance.

Results

SUD results in disruption of glutamate system, in nucleus accumbens, a critical brain area in the rewarding system. NAC reestablishes glutamate homeostasis restoring function of the cysteine-glutamate exchange in glial cells and reversing the downregulated GLT-1 receptor. Concerning its properties, evidence suggests that NAC is able to decrease drive, craving or compulsion to consume, making it particular useful in relapse prevention after achieving abstinence.

Conclusions

NAC has revealed itself as a promising therapeutic agent in SUD and its safety profile and favourable tolerability, as well as being an over-the-counter medication, adds to its interest. Data is still preliminary for the use of NAC in psychiatry disorders, due to the relatively small number of trials and their heterogeneous methodology. Larger studies are needed to confirm efficacy, optimal doses, long-term tolerability and side effects.

Recent advances on mycotic keratitis caused by dematiaceous hyphomycetes

Dematiaceous hyphomycetes (DH) are darkly pigmented fungi ubiquitously found all over the world as plant pathogens and saprophytes, and many of the members of this group have emerged as opportunistic pathogens. These fungi are responsible for a wide variety of infections including mycotic keratitis, which is considered as one of the major causes of corneal blindness, particularly in tropical and subtropical countries with an annual global burden of about 1 000 000 patients. The infection is more common in workers working in an outdoor environment. Moreover, trauma is found to be the most important predisposing cause of mycotic keratitis. Considerable delay in diagnosis and scarcity of effective pharmacological drugs are the major factors responsible for increased morbidity and visual impairment. Considering the crucial role of DH in mycotic keratitis, in the present review, we have focused on major DH with special emphasis on their pathogenicity, diagnosis and treatment strategies.

Cross-cultural validation of the Portuguese from Portugal version of the test for respiratory and asthma control in kids questionnaire

Summary

Objective. The Test for Respiratory and Asthma Control in Kids (TRACK) is a tool to assess asthma control in preschool children. This study aims to validate the Portuguese from Portugal version of the TRACK questionnaire. Methods. A prospective cohort study was carried out to assess their psychometric characteristics. Caregivers of 141 children under age 5 with asthma symptoms were enrolled. Results. Internal reliability was close to 0.70 (Cronbach's α). The test-retest reliability was 0.87. TRACK scores were different between well, partially, and non-controlled asthma groups (p less than 0.001). Patients rated as having better control showed an increase in TRACK scores. Conclusions. The Portuguese version of the TRACK questionnaire is accurate and reliable for monitoring asthma control. Its use may help to overcome challenges with the management of this age group.

What has changed during the state of emergency due to COVID-19 on an Academic Urology Department of a Tertiary Hospital in Portugal

Objetivo

Comparar la actividad del Servicio de Urología de un Hospital Universitario Portugués durante el estado de alarma y el periodo equivalente del año anterior. Comparamos el número de consultas electivas y pruebas diagnósticas urológicas, el número y el tipo de cirugías electivas, así como las características demográficas de los pacientes y las principales causas de ingreso al Servicio de Urgencias (SU) de Urología durante los dos periodos mencionados.

Materiales y métodos

Los datos de 691 pacientes que acudieron a urgencias desde el 18 de marzo de 2020 hasta el 2 de mayo de 2020 -y del mismo periodo del año anterior- se recogieron del software medico institucional. Los datos recopilados fueron edad, sexo, fecha de visita al servicio de urgencias, derivación desde otros hospitales, color del triaje, causa del ingreso, diagnóstico al alta y la necesidad de cirugía de urgencia u hospitalización. Con la intención de identificar las asociaciones entre las variables demográficas y clínicas con el hecho de haber sido sometido a una cirugía de urgencia (variable), se aplicaron modelos de regresión logística.

Resultados

El análisis multivariante mostró asociación entre el sexo del paciente con el hecho de ser sometido a una cirugía, con una disminución del 65,6% en las probabilidades para el género masculino. El periodo (COVID versus sin-COVID) no mostró una asociación significativa con la cirugía.

Conclusión

Nuestro departamento experimentó una reducción importante en la actividad. También observamos una reducción de las causas urgentes para acudir a los servicios de urgencias considerados menos graves. El porcentaje de casos que requirieron cirugía de urgencia y hospitalización fue mayor durante el periodo COVID.

Evaluation of the oral health condition of schoolchildren in the south of Brazil

In order to subsidize policies, actions and intersectoral strategies for health promotion, protection and recovery, it is important to establish the distribution of oral diseases in the target population. Thus, the present study aims at identifying the oral health condition of students from a network of schools run by a Social Welfare, not-for-profit, non-governmental institution in Brazil's Southern Region. This is a census approved by a competent Research Ethics Committee, carried out in a school environment in 2018, involving 1,243 children, 1,172 of which at 5 years old and 71 at 12 years old. All had impacts on oral health and caries rates (dmf / DMFT), occlusion (Foster & Hamilton and DAI) and fluorosis (Dean) evaluated by properly trained and calibrated dentists.The most prevalent impact on oral health, at both ages, was “difficulty in eating”. Students aged 12 and 5 years old showed, respectively, 0.28 and 1 tooth with caries experience; 5.8% and 5.3% with some need for treatment and a prevalence of malocclusion of 57.7% and 79%. Fluorosis was investigated only within the 12-year-old students and it was present in 26.8% of them. In view of the results, the planning of oral health actions in the schools of the social institution studied must privilege the actions of promotion, protection and recovery in the scope of malocclusions and strengthen those already implemented for caries disease. At the same time, a health surveillance system should be built and implemented for monitoring and assessment.

Key messages

Identifying the epidemiological profile of the target population contributes to the efficient allocation of financial resources and the establishment of assertive strategies to meet their needs. Epidemiological surveys allow us to know the prevalence and severity of the disease, its distribution and treatment needs, allowing health planning and subsidizing the evaluation of services.

Profile of incarcerated women in the interior of Brazil and the challenge of education in prison

According to the Ministry of Justice and Public Security, Brazil is fourth in the world position in relation to the absolute size of female prison population, with 42.000 women deprived of freedom (2016), behind the United States, China and Russia. Around 50% are young (&lt; 29 years old), 62% are black and 66% have not yet attended high school. This study aimed to characterize the profile of women incarcerated in a penitentiary in the interior of Brazil, through the survey of sociodemographic data, education, health, legal and life expectations. This is a descriptive and exploratory study conducted with 68 women (20 to 67 years old) in 2019 and 2020. Most women declared themselves black or brown (56%), incomplete elementary school (42%), have work experience (73%). Around 69% reported needing health treatment and 76% have already used psychoactive substances including alcohol, cigarettes, marijuana, cocaine or crack. The main reasons that led to the arrest were drug trafficking (54%) and theft (26%) and the majority (53%) are repeat offenders in prison system. Regarding the biggest dream of life, the main answers were related to family life (44%), having a job (26%) and access to education (20%). With these results, an extension project was proposed to offer a professional qualification in vegetable gardens, aromatic and medicinal plants for women prisoners. In addition to professional qualification, the project is dedicated to promoting debates on map of life, ethics, human relations, citizenship, gender, women's rights and health, quality of life, body and verbal expression, digital inclusion, food and nutrition security, entrepreneurship, cooperativism, solidary economy, rights and duties of the worker, aiming at better employment conditions. This research contributed to articulate actions between university and society, empower women through access to education and allowed the work team to develop competencies related to collaborative work and interdisciplinarity.

Factors associated with asthma control in 121 preschool children

BACKGROUND AND OBJECTIVE

There are controversial data about risk factors for uncontrolled asthma in preschool children. Objective: This study aims to explore the association between clinical and functional parameters and the lack of asthma control in preschool children.

METHODS

Children 3-5 years-old with asthma and healthy controls were recruited. A questionnaire was used to identify the potential risk factors of uncontrolled asthma as defined by GINA (Global INitiative for Asthma) criteria. Lung function and bronchial reversibility were evaluated through impulse oscillometry (IOS) and spirometry. Adjusted odds ratios (OR) were estimated based on multivariable generalized additive regression models. The discriminative ability of the models was measured by the area under the receiver operating characteristic curve (AUC).

RESULTS

121 children were included, 107 of which had asthma and 14 were healthy controls. Fifty-three patients (50%) had uncontrolled asthma. After adjustment, the variables associated with an increased risk of lack of control were: "More than 3 flare-ups in last 12 months", "moderate to severe rhinitis", "relative variation in post-bronchodilator FVC and FEV1". The AUC of the final models that included variation of FVC or FEV1 were 0.82 and 0.81, respectively. R5-20, R5-20% and AX z-score values of the healthy group were lower than those of children with asthma.

CONCLUSION

In preschool children, clinical and functional parameters are associated with uncontrolled asthma. More studies are needed to confirm usefulness of the IOS.

THU0363 EFFECTS OF NINTEDANIB IN PATIENTS WITH SYSTEMIC SCLEROSIS-ASSOCIATED ILD (SSC-ILD) AND NORMAL VERSUS ELEVATED C-REACTIVE PROTEIN (CRP) AT BASELINE: ANALYSES FROM THE SENSCIS TRIAL

Background:

In the SENSCIS trial in patients with SSc-ILD, nintedanib reduced the rate of decline in forced vital capacity (FVC) over 52 weeks. Elevated CRP is a marker of an inflammatory phenotype and has been associated with a greater rate of decline in FVC and higher mortality in patients with SSc.

Objectives:

To assess the effects of nintedanib in subgroups by CRP at baseline in the SENSCIS trial.

Methods:

Patients with SSc-ILD with onset of first non-Raynaud symptom <7 years and ≥10% fibrosis of the lungs on HRCT were randomised to receive nintedanib or placebo. We analysed the rate of decline in FVC (mL/year) over 52 weeks, the proportion of patients with an absolute increase in FVC ≥3% predicted (proposed as the minimal clinically important difference for improvement in FVC in patients with SSc-ILD), and absolute change from baseline in mRSS at week 52 in subgroups with normal vs elevated high-sensitivity CRP (≤4.99 vs >4.99 mg/L) at baseline.

Results:

Of patients with available data, 78/270 (28.9%) and 74/261 (28.4%) in the nintedanib and placebo groups, respectively, had CRP >4.99 mg/L at baseline. Compared with patients with lower CRP, those with CRP >4.99 mg/L included a similar proportion of patients who were ATA-positive (61.8% vs 60.2%, respectively), a greater proportion with diffuse cutaneous SSc (63.2% vs 49.3%) and had a higher mean mRSS (13.7 vs 10.2) and lower mean FVC % predicted (68.6% vs 73.9%). The adjusted annual rate of decline in FVC in the placebo group was numerically greater in patients with CRP >4.99 than ≤4.99 mg/L at baseline (-106.6 [SE 27.6] vs -83.0 [17.1] mL/year). The effect of nintedanib vs placebo on reducing the rate of decline in FVC was numerically more pronounced in patients with CRP >4.99 than ≤4.99 mg/L at baseline but the treatment-by-time-by-subgroup interaction p-value did not indicate heterogeneity in the effect of nintedanib between subgroups (p=0.70) (Figure). In the nintedanib and placebo groups, respectively, the proportions of patients with an absolute increase in FVC ≥3% predicted at week 52 were 20.4% and 15.0% in those with CRP ≤4.99 mg/L and 24.4% and 14.9% in those with CRP >4.99 mg/L at baseline (treatment-by-subgroup interaction p=0.59); adjusted mean changes in mRSS at week 52 were -2.2 (SE 0.3) and -2.1 (0.3) in those with CRP ≤4.99 mg/L (difference -0.1 [95% CI -1.0, 0.8]) and -2.3 (0.5) and -1.0 (0.5) in those with CRP >4.99 mg/L at baseline (difference -1.2 [-2.7, 0.2]; treatment-by-visit-by-subgroup interaction p=0.20).

Conclusion:

In the SENSCIS trial, the rate of decline in FVC over 52 weeks in the placebo group was numerically greater in patients with elevated CRP at baseline. Nintedanib reduced the rate of decline in FVC both in patients with normal and elevated CRP at baseline, with a numerically greater effect in patients with elevated CRP.

THU0330 EFFECTS OF NINTEDANIB IN PATIENTS WITH SYSTEMIC SCLEROSIS-ASSOCIATED ILD (SSC-ILD) AND DIFFERING EXTENTS OF SKIN FIBROSIS: FURTHER ANALYSES OF THE SENSCIS TRIAL

Background:

In the SENSCIS trial, nintedanib reduced the progression of SSc-ILD compared with placebo, as shown by a significantly lower rate of decline in forced vital capacity (FVC) over 52 weeks. There was no significant difference between treatment groups in change in modified Rodnan skin score (mRSS) at week 52. An mRSS of 18–25 has been proposed as an upper cut-off to enrich a cohort for skin-progressive patients. Progression of skin fibrosis has been associated with later progression of ILD.

Objectives:

To assess the effects of nintedanib on the rate of FVC decline and change in mRSS in the SENSCIS trial in subgroups by mRSS <18 and ≥18 at baseline.

Methods:

Patients with SSc-ILD with onset of first non-Raynaud symptom <7 years before screening and ≥10% fibrosis of the lungs on a high-resolution computed tomography scan were randomised to receive nintedanib or placebo. We analysed the rate of decline in FVC (ml/year) over 52 weeks and the change from baseline in mRSS at week 52 in subgroups by mRSS (<18; ≥18) at baseline.

Results:

In the nintedanib and placebo groups, respectively, 219/288 (76.0%) and 226/288 (78.5%) patients had mRSS <18 at baseline. Compared with those with mRSS <18, patients with mRSS ≥18 had a lower mean FVC % predicted (68.3% vs 73.7%) and greater proportions were taking mycophenolate at baseline (58.1% vs 45.6%), were anti-topoisomerase I antibody positive (67.4% vs 58.7%) and had diffuse cutaneous SSc (100% vs 37.8%). The mean (SE) annual rate of decline in FVC in the placebo group was numerically greater in patients who had mRSS ≥18 than mRSS <18 at baseline (-131.7 [29.2] mL/year vs -81.4 [15.4] mL/year). The effect of nintedanib vs placebo on reducing the annual rate of decline in FVC was numerically more pronounced in patients with mRSS ≥18 (difference: 88.7 mL/year [95% CI 7.7, 169.8]) than mRSS <18 (difference: 26.4 mL/year (95% CI -16.8, 69.6) at baseline, but statistical testing did not indicate heterogeneity in the treatment effect of nintedanib between subgroups (p=0.18 for treatment-by-time-by-subgroup interaction) (Figure). In the nintedanib and placebo groups, respectively, changes in mRSS at week 52 were -2.2 (0.3) and -2.1 (0.3) (difference -0.1 [95% CI -1.0, 0.7]) in patients with mRSS <18 at baseline and -2.1 (0.7) and -1.6 (0.7) (difference -0.6 [95% CI -2.1, 1.0]) in patients with mRSS ≥18 at baseline (p=0.62 for treatment-by-visit-by-subgroup interaction).

Conclusion:

In the placebo group of the SENSCIS trial, the rate of decline in FVC over 52 weeks was numerically greater in patients with mRSS ≥18 than <18 at baseline, while reductions in mRSS were similar. A lower rate of FVC decline was observed in patients treated with nintedanib than placebo both in patients with mRSS ≥18 and <18 at baseline.

SAT0329 IS THE RATE OF LUNG FUNCTION DECLINE THE SAME IN PATIENTS WITH SYSTEMIC SCLEROSIS-ASSOCIATED ILD (SSC-ILD) WHO EXPERIENCE WEIGHT LOSS? DATA FROM THE SENSCIS TRIAL

Background:

In the SENSCIS trial, nintedanib reduced the progression of SSc-ILD vs placebo, as shown by a lower rate of decline in forced vital capacity (FVC). The adverse event (AE) profile of nintedanib was characterised mainly by gastrointestinal (GI) events, including weight loss.

Objectives:

Assess FVC decline and AEs in subgroups by weight loss ≤5% vs >5% over 52 weeks in the SENSCIS trial.

Methods:

Patients with SSc-ILD with first non-Raynaud symptom <7 years before screening and ≥10% fibrosis of the lungs on an HRCT scan were randomised to nintedanib or placebo. In a non-randomised comparison, we analysed the rate of decline in FVC (mL/year) and AEs over 52 weeks in subgroups by weight loss (≤5% vs >5%) over 52 weeks.

Results:

In the nintedanib (n=288) and placebo (n=288) groups, respectively, 112 (38.9%) and 43 (14.9%) patients had weight loss >5% over 52 weeks. At baseline, patients with weight loss >5% over 52 weeks had a higher mean age (57.0 vs 52.9 years), greater proportion of females (81.3% vs 72.9%), and similar mean BMI (26.5 vs 25.7 kg/m2, respectively) and FVC % predicted (71.0% vs 73.1%, respectively) vs patients with weight loss ≤5%. In the placebo group, the mean (SE) annual rate of decline in FVC was similar between patients who had weight loss ≤5% and >5% over 52 weeks (-92.7 [14.7] mL/year and -96.4 [34.9] mL/year, respectively). The estimated annual rate of decline in FVC was lower in patients treated with nintedanib than placebo, with between-group differences in patients who had weight loss ≤5% and >5% of 49.9 mL/year [95% CI 4.2, 95.6]) and 30.2 mL/year [95% CI -50.5, 110.9]), respectively, with no evidence of heterogeneity between subgroups by weight loss (p=0.68 for interaction). Standardised differences in baseline values of potential confounders were <0.2 (indicating negligible differences). The most frequent AEs in patients treated with nintedanib were diarrhoea (74.4% and 77.7% of patients with weight loss ≤5% and >5%, respectively), nausea (30.1% and 33.9%, respectively) and vomiting (19.3% and 33.3%, respectively). In the nintedanib and placebo groups, respectively, AEs leading to discontinuation of study drug occurred in 17.0% and 8.6% of patients with weight loss ≤5%, and 14.3% and 9.3% of patients with weight loss >5% over 52 weeks.

Conclusion:

In the SENSCIS trial in patients with SSc-ILD, a greater proportion of patients treated with nintedanib than placebo had weight loss >5% over 52 weeks. The rate of decline in FVC was numerically lower in the nintedanib group than in the placebo group both in patients with weight loss ≤5% and >5% over 52 weeks. AEs leading to discontinuation of nintedanib were not more frequent in patients with weight loss >5% vs ≤5%.

SAT0313 CORRELATION BETWEEN PROGRESSION OF SKIN FIBROSIS AND PROGRESSION OF INTERSTITIAL LUNG DISEASE (ILD) IN PATIENTS WITH SSC-ILD: DATA FROM THE SENSCIS TRIAL

Background:

In the SENSCIS trial in patients with SSc-ILD, nintedanib reduced the rate of decline in FVC over 52 weeks vs placebo, with no difference between groups in change in mRSS.

Objectives:

Analyse correlation between progression of skin fibrosis and progression of SSc-ILD in the SENSCIS trial.

Methods:

Patients with SSc-ILD were randomised to receive nintedanib or placebo until the last patient reached week 52 but for ≤100 weeks. We calculated Spearman correlation coefficients between FVC (mL) at baseline and change from baseline in mRSS, mRSS at baseline and change from baseline in FVC (mL), and changes from baseline in mRSS and FVC at weeks 52 and 100 in all patients. We analysed the rate of decline in FVC (mL/year) in patients who did and did not have progression of skin fibrosis (relative change from baseline in mRSS >25% and absolute change from baseline >5 points) at week 52.

Results:

In the nintedanib (n=288) and placebo (n=288) groups, respectively, mean (SD) baseline FVC (mL) was 2459 (736) and 2541 (816) and mRSS was 11.3 (9.2) and 10.9 (8.8); 53.1% and 50.7% had dcSSc;18.4% and 16.0% had progression of mRSS at week 52. No meaningful correlations were observed in analyses between mRSS and FVC (Table). The mean (SE) annual rate of decline in FVC in the placebo group was similar in patients who did and did not have progression of mRSS (-95.2 [27.1] and -91.4 [15.7] mL/year, respectively). The effect of nintedanib vs placebo on reducing the rate of decline in FVC was numerically more pronounced in patients who did not have progression of mRSS vs those who did (difference [95% CI] 44.3 mL/year [0.6, 88.1] vs 24.6 [-53.7, 102.9]), but the interaction p-value (0.66) did not indicate heterogeneity in treatment effect between subgroups.

Conclusion:

In the SENSCIS trial, the proportion of patients who had progression of skin fibrosis over 52 weeks was low, without significant differences between placebo and nintedanib. No meaningful correlations were observed between skin fibrosis at baseline or progression of skin fibrosis and progression of SSc-ILD. The rate of decline in FVC was similar between patients who did and did not have progression of mRSS. These findings suggest that in the overall patient population in the SENSCIS trial, progression of skin fibrosis and progression of ILD were distinct manifestations of disease progression.

SAT0345 IS THERE A DIFFERENCE BETWEEN THE SEXES IN THE RATE OF PROGRESSION OF SYSTEMIC SCLEROSIS-ASSOCIATED ILD (SSC-ILD)? DATA FROM THE SENSCIS TRIAL

Background:

Previous studies suggested that male sex may be associated with a greater rate of decline in FVC in patients with SSc-ILD. In the SENSCIS trial, nintedanib reduced the rate of FVC decline over 52 weeks vs placebo.

Objectives:

Analyse the rate of decline in FVC and the efficacy and safety of nintedanib in the SENSCIS trial in subgroups by sex.

Methods:

Patients with SSc-ILD with first non-Raynaud symptom <7 years before screening and ≥10% fibrosis of the lungs on HRCT were randomised to nintedanib or placebo. We analysed the rate of decline in FVC (mL/year) and adverse events over 52 weeks in male and female patients.

Results:

Of 576 patients, 433 (75.2%) were female. Compared with males, the female subgroup included a smaller proportion of White patients (64.7% vs 74.8%), a smaller proportion on mycophenolate at baseline (46.9% vs 53.1%), a greater proportion of ATA positive patients (63.3% vs 53.1%), and had a lower mean weight at baseline (66.6 vs 79.1 kg). FVC % predicted (72.8% vs 71.7%) and mRSS (11.2 vs 10.8) were similar in females and males. The adjusted annual rate of decline in FVC in the placebo group was numerically greater in male than female patients (-126.8 [SE 29.0] vs -82.0 [16.2] mL/year). The estimated effect of nintedanib vs placebo on reducing the rate of decline in FVC was numerically more pronounced in males than females (difference: 58.6 [95% CI -18.0, 135.1] vs 34.6 [-9.3, 78.4] mL/year), but the interaction p-value did not indicate heterogeneity in the treatment effect between subgroups (p=0.59). Among nintedanib-treated patients, diarrhoea was reported in similar proportions of females and males (74.7% vs 79.1%); nausea, vomiting and liver test abnormalities were reported in greater proportions of females vs males (35.3% vs 19.4%, 28.1% vs 13.4%, and 15.4% vs 9.0%), while serious adverse events were more frequent in males (32.8% vs 21.3%). In the nintedanib and placebo groups, respectively, adverse events leading to treatment discontinuation were reported in 16.7% and 8.5% of females and 13.4% and 9.2% of males.

Conclusion:

In the SENSCIS trial in patients with SSc-ILD, the annual rate of decline in FVC in the placebo group was numerically greater in male than female patients. The rate of FVC decline was lower with nintedanib than placebo both in males and females. The safety profile of nintedanib was similar between males and females.

Hikikomori goes global: A Portuguese case

Introduction

Hikikomori, a form of severe social isolation, once characterized as a Japanese cultural-bond behavior with social and economic consequences, it is now being described in other countries. Its presentation mimics some clinical features of various classified mental diseases, such as prodromal phase of schizophrenia, personality disorders, Internet dependence, social phobia or depression, without fulfilling their defining criteria.

Objectives/method

This work aimed to do a brief review of this subject, describing one case that is probably the first ever reported in Portugal, comparing it with similar cases around the world.

Results

The patient was a 22-year-old male, taken to psychiatry evaluation after 4 years of social withdrawal, avoiding or blocking any contact even with family members, which resulted in work and school impairment. He spent most of his days locked at his room, investing his time in particular interests and Internet use, only leaving to eat or do his basic hygiene. At that time, he presented no affective or psychotic symptoms and perceived his behavior as egosintonic. After six appointments with psychotherapeutic approach, he was able to get a job and improved his communication with the others, especially with family.

Discussion/conclusion

This case fits most of the reports found on literature, in its presentation and clinical management. Hikikomori is not considered yet a disorder and further documentation of these cases is still needed to define its place in psychiatric nosology.

The Impact of Parental Schizophrenia in the Development of Behavioral Disorders and Mental Illness in Children

Introduction

Parental schizophrenia will potentially cause dysfunction in mother-child relationships, and it will also cause difficulty in adapting to motherhood.

Objectives

We aim to study the implications of the relationship between mothers with schizophrenia and their children. The psychosocial environment and the impact of dysfunctional relationship in social skills development may cause behavioral disorders in children and further development of severe mental illness taking into account genetic factors and biopsychosocial factors.

Methods

Non systematic literature review, through the Pubmed and Medline database, with time constraints.

Results

The development of schizophrenia is related to genetic and environmental factors. Children of parents with schizophrenia are at increased risk of developing psychiatric disorder compared to the general population. It was found early behavioral disorders, starting between 5 and 8 years old and the difficulties in social interaction may arise at this age and remain until adulthood.

Conclusions

It is important to assess the level of acquisition of social skills in children and families when there is a direct relationship with schizophrenia. It may be important in the future, monitorize the development of these children, as well as be aware of the surrounding social and family environment, to identify and manage early in the presence of behavioral disorders and possible development of serious mental illness. An early intervention at the level of social deficits in children can be a preventive intervention of later schizophrenia development.

Ocular involvement in systemic lupus erythematosus patients: a paradigm shift based on the experience of a tertiary referral center

Objective

To evaluate ocular involvement in a cohort of systemic lupus erythematosus (SLE) patients of a tertiary referral center and to compare the results with the existing literature.

Methods

Patients underwent a complete ophthalmological evaluation, including visual acuity, slit-lamp examination, fluorescein staining, Schirmer-I test, Goldmann applanation tonometry, fundoscopy, 10-2 automated threshold visual fields, fundus autofluorescence and spectral-domain optical coherence tomography to screen for hydroxychloroquine (HCQ) macular toxicity.

Results

A total of 161 patients (16 men and 145 women) were enrolled in this study. The mean age was 47.6 years and the mean disease duration was 11.5 years. Fifty patients (31.1%) had at least one ocular manifestation of SLE. The most frequent manifestation was dry eye syndrome (12.4%), immediately followed by cataracts (11.2%) and HCQ macular toxicity (11.2%). Among patients with HCQ maculopathy, two presented with an atypical spectral-domain optical coherence tomography pattern. Five patients (3.1%) presented with glaucoma, two patients (1.2%) presented with SLE retinopathy while only one presented with lupus choroidopathy (0.6%).

Conclusions

Compared with previous studies, we conclude there has been a significant reduction in disease-related ocular complications, particularly those associated with poor systemic disease control. On the other hand, drug and age-related complications are assuming a prominent role in the ophthalmic care of these patients.

P331Effect of exercise stress test on platelet function in patients with recent acute myocardial infarction

Background

Exercise-based cardiac rehabilitation for coronary artery disease (CAD) is associated with lower cardiovascular mortality. On the other hand, acute strenuous exercise has been linked to cardiovascular complications such as acute myocardial infarction (AMI) and sudden cardiac death. One of the pathophysiological mechanisms involved in these outcomes might be an increase in platelet aggregability after exercise. Although previous studies showed higher platelet aggregability after exercise among stable CAD patients on aspirin treatment, there is no data regarding the effect of exercise on platelet activity in post-AMI patients on dual anti-platelet therapy (DAPT).

Purpose

To evaluate the effect of high-intensity exercise on platelet aggregability in sedentary post-AMI patients on DAPT.

Methods

Platelet function was analyzed immediately before and after maximal cardiopulmonary exercise test (CPET) on cycle ergometer utilizing a personalized ramp protocol and aiming to achieving peak exercise in around 10 min. The CPET was done within 31±4 days after uncomplicated AMI. Platelet aggregability was assessed by Multiplate®ADPtest (MP-ADP) and Multiplate® ASPItest (MP-ASPI) measured as area under the curve (AUC). Reticulated platelets were measured concomitantly to MP-ADP e MP-ASPI using a fully automated flow cytometer (Sysmex XN-2000®) to determine absolute immature platelet count (IPC) per 103/microliter. Continuous variables were expressed as means ±standard deviation or as median and 25th–75th percentiles if not Gaussian distributed. Comparisons between the pre- and post-CPET assessments were performed using Wilcoxon signed rank test.

Results

We analyzed 81 sedentary patients (mean age 58.3±10.1 years-old, 76.5% men) after AMI (50.6% with ST-elevation myocardial infarction, mean left ventricular ejection fraction after index event 55±11.7%, 98.8% on statin and 85.5% on beta-blocker treatment). Platelet aggregability, either by MP-ADP or MP-ASPI, and IPC were significantly increased after CPET (table).

Platelet function after CPET Before CPET After CPET p-value Multiplate® ADPtest (AUC) – median (25th–75th percentiles) 32.0 (22.0–48.5) 37.0 (26.0–55.2) 0.003 Multiplate® ASPItest (AUC) – median (25th–75th percentiles) 17.0 (12.7–22.0) 22.0 (16.7–28.0) <0.001 Immature platelet count (103/microliter) – median (25th–75th percentiles) 9.5 (6.8–13.8) 9.6 (6.6–16.5) 0.006 CPET: cardiopulmonary exercise test; AUC: area under the curve.

Conclusion

On this post-AMI population, platelet was hyperactivated after exercise stress test despite the use of DAPT. These findings suggest that, even when properly treated, post-AMI patients might be at higher risk of ischemic complications after high-intensity exercises, reinforcing the importance of tailoring exercise prescription in this population.

P4539Android to gynoid fat ratio and its association with functional capacity in male patients with heart failure

Background

Obesity may have a protective role in patients with heart failure with reduced ejection fraction (HFrEF), a phenomenon known as obesity paradox. However, some patients can also present sarcopenic obesity with similar exercise intolerance as lean patients with muscle wasting. However, the impact of body fat distribution on exercise intolerance in HFrEF is unknown.

Purpose

To study the association between android to gynoid fat ratio and functional capacity (VO2 peak) in male patients with HFrEF.

Methods

We enrolled 118 male with HFrEF with left ventricular ejection fraction (LVEF) <40%, mean age of 56±7 years old. Body composition was measured with dual x-ray absorptiometry. Android and gynoid fat were measured and the ratio between them was calculated (A/G ratio). Appendicular lean mass (ALM) was calculated as the lean muscle mass of both arms and legs divided by the height squared. Sarcopenic obesity was defined according to Foundation for the National Institutes of Health criteria (ALM adjusted for body mass index <0.789 for men). Muscle strength was assessed using the handgrip dynamometer (cutoff point for sarcopenia was defined as proposed by European Working Group on Sarcopenia in Older People). Blood sample was used to measure metabolic and hormonal parameters.

Results

Of those 118 patients, 15 (12.7%) showed sarcopenic obesity. In our cohort, the median A/G ratio was 0.55. A/G ratio >0.55 was detected in 60 patients. Weight and BMI were higher in patients with A/G ratio >0.55 (P<0.001). Absolute peak VO2 was similar between patients with A/G ratio lower or higher than 0.55 (1.48±0.40 vs. 1.43±0.40 L/min, P=0.559), while relative peak VO2 was lower in patients with A/G ratio >0.55 (18.7±5.3 vs. 22.5±6.1 mL/kg/min, P<0.001). LVEF, total cholesterol, LDL, haemoglobin, and IGF-1 were similar between patients with A/G ratio lower or higher than 0.55 (P>0.05). On the other hand, HDL, total testosterone, free testosterone, and DHEA were lower in patients with A/G ratio >0.55 (P<0.05). Logistic regression analysis showed A/G Ratio >0.55 to be independently associated with reduced peak VO2 (L/min) adjusted for age, BMI, LVEF, presence of sarcopenia, anabolic hormones, and haemoglobin (odds ratio 3.895, 95% CI 1.030–14.730, p=0.045).

Conclusion

Our data suggest that body fat distribution, particularly android and gynoid fat composition, might have an important adverse role on functional capacity in male patients with HFrEF.

P4132Decreased myocardial native T1 times and impaired myocardial contractility in young anabolic androgenic steroids users

Background

Anabolic androgenic steroids (AAS) have been associated with several injuries on the cardiovascular system. AAS abuse may have a direct toxic effect on the myocardium that could lead to cardiac function and structure alterations. Clinical and forensic cases have been reported myocardial fibrosis in AAS users. Myocardial fibrosis increases the risk of heart failure and sudden death. However, recent studies did not show evidence of focal myocardial fibrosis and diffuse myocardial fibrosis in AAS users using T1-mapping techniques. Thus, it remains unclear the association between AAS and cardiac structure alterations.

Purpose

The aim of this study was to evaluate cardiac structure by cardiovascular magnetic resonance (CMR) imaging with late-gadolinium enhancement (LGE), cardiac T1-mapping and extracellular volume measurements (ECV). Additionally, we also evaluated the cardiac contractility by CMR and echocardiography in young AAS users.

Methods

Twenty strength-trained AAS users (AASU) age 29±5 yr, 20 age-matched strength-trained AAS nonusers (AASNU), and 10 sedentary controls (SC) were enrolled. Cardiac structure was assessed by LGE, native T1-mapping and ECV. Cardiac contractility was evaluated as cardiac strain measured by CMR (feature tracking imaging technique) and echocardiography (speckle tracking technique).

Results

Global native T1 times [753 (683–870) vs 916 (815–1239) vs 1205 (825–1242) ms, respectively, p=0.03], and native T1 times at the left ventricle mid-ventricular slice [813 (695–1096) vs 922 (825–1095) vs 1140 (840–1322) ms, respectively, p=0.03] were lower in AASU compared with AASNU and SC. Mid-ventricular ECV was similar between AASU, AASNU and SC (22±6 vs 23±4 vs 24±4%, respectively, p=0.37). Focal myocardial fibrosis was found in 2 individuals (11%) of AASU. The mid anteroseptal and mid inferoseptal were the most affected segments. The total estimated mass of the LV mass was 1.25 g (0.65%). Three participants of SC showed focal myocardial fibrosis. The mid anterolateral, mid inferolateral and mid inferomedial were the most affected segments. The total estimated mass of the LV mass was 3.43 g (2.30%). In contrast, none of the AASNU had myocardial fibrosis. By CMR, AASU showed a lower medial radial strain (30±8 vs. 38±6%, p<0.01), medial circumferential strain (−17±3 vs −20±2%, p<0.01) and global longitudinal strain (−17±3 vs −20±3%, p<0.01) compared with AASNU. Echocardiography also demonstrated a lower 4CH longitudinal strain in AASU compared with AASNU (−15.5±3 vs −18.3±2%, p=0.03). Moreover, the AASU shower a higher left ventricle mass compared with AASNU and SC (185±20 vs 130±17 vs 112±14 g, respectively, p<0.01).

Conclusion

This study indicates that AAS abuse may be associated with decreased myocardial native T1 times, impaired myocardial contractility and focal myocardial fibrosis. These myocardial structural and functional alterations may be associated to unadapted cardiac hypertrophy in young AAS users.
