The presence and outcome of biliary sphincter disorders in liver-transplant recipients according to the Rome IV classification

Background

Biliary sphincter disorders after liver transplantation (LT) are poorly described. We aim to describe the presence and outcome of patients with papillary stenosis (PS) and functional biliary sphincter disorders (FBSDs) after LT according to the updated Rome IV criteria.

Methods

We reviewed all endoscopic retrograde cholangiopancreatographies (ERCPs) performed in LT recipients between January 2003 and December 2019. Information on clinical and endoscopic findings was obtained from electronic health records and endoscopy databases. Laboratory and clinical findings were collected at the time of ERCP and 1 month after ERCP.

Results

Among the 1,307 LT recipients, 336 underwent 849 ERCPs. Thirteen (1.0%) patients met the updated Rome IV criteria for PS [former sphincter of Oddi dysfunction (SOD) type I] and 14 patients (1.0%) met the Rome IV criteria for FBSD (former SOD type II). Biliary sphincterotomy was performed in 13 PS and 10 FBSD cases. One month after sphincterotomy, bilirubin, gamma-glutamyl transferase and alkaline phosphatase levels decreased in 85%, 61%, and 92% of those in the PS group (P = 0.019, 0.087, and 0.003, respectively) and in 50%, 70%, and 80% of those in the FBSD group (P = 0.721, 0.013, and 0.093, respectively). All the 14 patients initially suspected of having a FBSD turned out to have a different diagnosis during the follow-up.

Conclusions

PS after LT is uncommon and occurs in only 1% of LT recipients. Our data do not support the presence of an FBSD after LT. Sphincterotomy is a safe and effective procedure in LT recipients with PS.

AB0117 CARDIOVASCULAR MORBIMORTALITY IN RHEUMATOID ARTHRITIS: A 5 YEAR FOLLOW-UP STUDY

Background:

Rheumatoid arthritis (RA) is characterized by elevated cardiovascular morbimortality. RA patients have a higher risk to develop cardiovascular comorbidities when compared to the general population, being the main cause of mortality in these patients. Cardiovascular risk factors (CVRF) are well known, but their management is not optimal, increasing the risk of having a major heart disease (1).

Objectives:

To assess the prevalence of the main causes of morbimortality and development of CVRF in RA patients during a five-year follow-up period.

Methods:

A longitudinal and prospective study of a RA cohort from 2014-2019 was performed in a Cardio Rheumatology outpatient clinic at the University Hospital “Dr. Jose E. Gonzalez”, UANL. Patients aged 40-75 years with RA according to ACR/EULAR 2010 criteria were recruited. At both visits, demographic, clinical variables, and lipid profile were recorded. Outcomes included the development of cardiovascular comorbidity: hypertension, diabetes mellitus (DM), dyslipidemia, myocardial infarction, stroke. Survival probabilities and outcomes cumulative frequencies were calculated according to the Kaplan-Meier lifetime analysis method. Descriptive analysis: frequencies (%), mean (SD), or median (q25-q75). Comparisons with McNemar and Student’s t test.

Results:

A follow-up was done in a total of 92 patients. During the follow-up, 9 patients (9.8%) died, 3 died of cardiovascular death (one myocardial infarction and two strokes). The mean age of death was 67.2 ± 10.5 years. CVRF at baseline (T0) and after five years (T5) are shown in table 1. Of the remain 83 patients, 11 patients (13.3%) developed hypertension (p=0.001), 8 (9.6%) patients developed DM (p=0.031). The number of patients with dyslipidemia decreased significantly to 14 (16.9%) (p=0.031), 4 (4.8%) developed a stroke. A survival probability of 95.7% was found at the five-year follow-up from the time of entry into the cardio rheumatology clinic (Figure 1 next page) and a 30.1% probability of developing cardiovascular comorbidity.

Conclusion:

This long-term study provides updated information on RA morbimortality characteristics in our population. Patients with RA still develop significant cardiovascular comorbidities despite current treatment. In this cohort, hypertension and DM became more prevalent, and a 96% cardiovascular death-free survival was found. Is imperative to increase the effort in determining optimal markers and therapeutic measures to continue with the prevention of these comorbidities.

POS1074 CARDIOVASCULAR RISK FACTORS IN A MEXICAN MESTIZO PATIENTS WITH PSORIATIC ARTHRITIS

Background:

Psoriatic Arthritis (PsA) is a chronic inflammatory arthropathy that affects 14%-30% of patients with skin and/or nail psoriasis. Patients with psoriatic arthritis (PsA) have a higher prevalence of traditional cardiovascular (CV) risk factors and an increased risk of developing cardiovascular diseases (1), such as acute myocardial infarction, cerebrovascular accident, peripheral vascular disease and heart failure. Despite the evidence patients with PsA are inadequately screened and undertreated for CV risk factors (CVRF), highlighting a gap in preventive medicine to adjust cardiovascular therapies(2).

Objectives:

The aim of the study is to determine the main CVRF in Mexican Mestizo patients with a diagnosis of PsA and to compare it with healthy controls. Additionally, to assess the impact of the diagnosis of PsA on the presence on these cardiovascular comorbidities.

Methods:

A cross-sectional, observational, and comparative study of ninety-six patients with PsA between 40-75 years who fulfilled CASPAR criteria 2006. Patients were matched by age and gender with non-PsA subjects. A medical history and physical exam were performed, also a blood sample was collected during the first visit. Chi square and Student´s t test were used for comparations between groups. A binary logistic regression was performed including the traditional CVRF (type 2 diabetes mellitus, hypertension, obesity, and active smoking), age and the diagnosis of PsA. A p value <0.05 was considered statistically significant.

Results:

There were 58 (60.4%) women in each group with a mean of 53 years. Patients with PsA showed a higher prevalence of hypertension (HTN) compared to healthy controls (35.4% vs 19.8%, respectively, p = 0.015). Additionally, there was a significant difference in the diagnosis of dyslipidemia (42.7% vs 22.9%, p = 0.003).We found no statistically difference between the two groups in type 2 diabetes mellitus, active smoking and, obesity (Table 1. below).

Conclusion:

Patients with PsA have a higher prevalence of HTN and dyslipidemia. The diagnosis of PsA seems to be an independent factor for the presence of dyslipidemia. It is important for rheumatologists to identify those patients who could benefit from adjust antirheumatic and cardiovascular therapies due to their impact on morbidity and mortality.

AB0842 CESAREAN SECTION IN MEXICAN WOMEN WITH AUTOIMMUNE RHEUMATIC DISEASES

Background:

Rheumatic diseases occur among women of childbearing age, adverse events during pregnancy in rheumatic diseases have been frequently reported. Mexico has one of the largest prevalence of cesarean section in women which negatively impacts the product.

Objectives:

The objective of this study is to describe the frequency of cesarean section in women with autoimmune rheumatic diseases compared to a control group.

Methods:

We conducted a cross-sectional and retrospective study in patients from the pregnancy and rheumatic diseases clinic, and the Obstetrics department form the University Hospital “Dr. José E. González” in Northeast Mexico. Women with autoimmune rheumatic diseases that gave birth between August 2017 to December 2020 were included. All the data, including the way of birth was retrieved from the clinical files.

Results:

One hundred and twelve patients were included (56 in the rheumatic disease group and 56 women without rheumatic diseases), two of them suffered miscarriage (one from the rheumatic disease group and 1 from the control group) giving a total of 110 products. The mean age was 29.6 years for the rheumatic patients and 24.6 for the control group. The most frequent rheumatic disease was RA in 22 patients (39.2%), followed by SLE in 13 patients (23.21%).

From the 56 pregnancies on the rheumatic disease group more than half ended by cesarean section (n=33, 58.92%) and there were 22 simple vaginal delivery. Table 1. On the control group there were 24 cesarean section procedures and 31 simple vaginal delivery. The indications for cesarean sections are presented in Figure 1. No statistically significant difference was found on cesarean section prevalence between both groups (p=0.389).

The most common indication for cesarean section in all patients was previous cesarean procedure. (n=12, 36.36%). There were more pathological fetal cardiotocographic changes (PFCC) as an indication for cesarean section on the rheumatic diseases group (n=11, p 0.002) compared with the control group (n=1).

Conclusion:

A higher prevalence of cesarean sections was found in women with rheumatic diseases versus women without rheumatic diseases, although this difference was not statistically significant. Studies with a higher sample size are necessary to elucidate the complications and differences between both groups.

POS1404 ECHOCARDIOGRAPHIC FINDINGS IN SYSTEMIC LUPUS ERYTHEMATOSUS PATIENTS AND ITS RELATION TO ANTIBODIES TITERS

Background:

Systemic lupus erythematosus (SLE) is a chronic and autoimmune disease characterized by systemic involvement. Patients with SLE have accelerated atherosclerosis, resulting in an up to nine-fold increased risk of cardiovascular disease, compared to the general population (1), being the leading cause of death for these patients. Speckle tracking echocardiography (STE) is an accurate technique to estimate myocardial function and deformation.

Objectives:

This study aims to determine the association between echocardiographic findings and the presence of antibodies in SLE patients.

Methods:

This was a cross-sectional and observational study. A total of forty-three patients ≥18 years with a diagnosis of SLE according to EULAR/ACR 2019 criteria were included for this study. Those with a history of cardiovascular disease (myocardial infarction, cerebrovascular accident, or peripheral arterial disease) and pregnancy were excluded. Transthoracic echocardiogram was performed and reviewed by 2 board-certified cardiologists, in all study subjects. Blood samples obtained from all patients were analyzed for the following: anti-nuclear antibodies (ANA), anti, SSA/Ro, SSB/La antibodies, anti-cardiolipin antibodies (IgA, IgM, IgG), and complement levels. Distribution was evaluated with the Kolmogorov-Smirnov test. Correlations between numerical variables were done using Spearman’s rho, considering two-tailed p-values <0.05 as statistically significant.

Results:

The 39 female patients (90.7%) and 4 male patients (9.3%) had a mean age of 35.5 ± 12.0 years and a median disease duration of 72 months (14-132). At the time of inclusion, 90.7% of the patients were being treated with glucocorticoids and antimalarials. Concerning traditional cardiovascular risk factors; 20.9% of the patients had hypertension, 7.0% had dyslipidemia, 2.3% had diabetes mellitus and 18.6% were active smokers. Correlations between echocardiographic findings and antibodies are shown in Table 1. We found a moderate positive correlation between global circumferential strain and IgA anticardiolipin antibody (r=0.507, p=0.002), a low positive correlation in left ventricular ejection fraction with anti-Ro (r=0.397, p=0.012) and anti-La (r=0.397, p=0.012) and a low positive correlation between TAPSE and C3 levels (r=0.396, p=0.013).

Conclusion:

There is an association between anticardiolipin antibody titers, anti-Ro, and anti-La with echocardiographic alterations. All SLE patients especially those who had positive antibodies should be screened for the presence of structural cardiac abnormalities. STE can be helpful as a noninvasive diagnostic tool, that could result in earlier treatment and prognosis.

POS0483 SUBCLINICAL ATHEROSCLEROSIS IN THE FIRST FIVE YEARS OF RHEUMATOID ARTHRITIS DIAGNOSIS

Background:

Patients with rheumatoid arthritis (RA) have a higher risk of developing a cardiovascular (CV) event than the general population, due to an accelerated process of atherosclerosis (1), which has been documented to begin in early stages of the disease and is directly associated with systemic inflammation (2).

Objectives:

The aim of this study was to compare the prevalence of subclinical atherosclerosis detected by carotid ultrasound (US) in patients with RA in the first five years of diagnosis and healthy controls.

Methods:

This was a cross-sectional, observational, and comparative study. A total of 53 patients aged 40-75 years old, with RA diagnosis, in the previous five years, according to the 2010 ACR/EULAR classification criteria, and 53 controls matched by age (±5 years), gender and comorbidities were included in this study. Subjects with a previous CV event, such as myocardial infarction, cerebrovascular event and peripheral arterial disease, another connective tissue disease and pregnant women were excluded from this study. A high-resolution B-mode carotid US was performed in all study subjects. Subclinical atherosclerosis was evaluated as the presence of carotid plaque (CP) or an increased carotid intima media thickness (cIMT). CP was defined as a cIMT ≥1.2mm or a focal narrowing ≥0.5mm of the surrounding lumen, and an increased cIMT was defined as a value ≥0.8mm. Distribution was evaluated with the Kolmogorov-Smirnov test. Comparisons were done with χ2 test and Fisher’s exact test for qualitative variables, and Student’s t test and Mann-Whitney’s U test for quantitative variables. A p-value <0.05 was considered statistically significant.

Results:

Comparisons of demographic characteristics showed no differences between the RA group and the control group (Table 1). When comparing carotid US findings there was a difference in the presence of CP, being more prevalent in RA patients (26.4% vs 11.3%, p=0.047), in the presence of an increased cIMT, being more prevalent in RA patients (34.0% vs 3.8%, p=<0.001), in the cIMT as a quantitative variable, being higher in RA patients (0.70mm vs 0.59mm, p=<0.001 in the right carotid artery, and 0.75mm vs 0.60mm, p=0.001 in the left carotid artery), and in the presence of subclinical atherosclerosis overall, being more prevalent in RA patients (52.8% vs 18.9%, p=<0.001) (Figure 1).

Conclusion:

Patients with RA in the first five years of diagnosis have a higher prevalence of subclinical atherosclerosis than the general population. CV evaluation including a carotid US should be done at the time of diagnosis of RA patients, and subsequently it must be individualized according to the CV risk of each patient, with a maximum of five years to identify those patients who would benefit from an opportune treatment.

POS1392 ECHOCARDIOGRAPHIC FINDINGS IN PSORIATIC ARTHRITIS, RHEUMATOID ARTHRITIS AND CONTROLS

Background:

Psoriatic arthritis (PsA) is a chronic inflammatory arthropathy associated with cardiovascular abnormalities (1). The echocardiography is a non-invasive tool useful in the detection of cardiac abnormalities, which may be the only manifestation of cardiac involvement preceding a global dysfunction. However, echocardiographic differences between PsA patients, rheumatoid arthritis (RA) patients, and controls have not yet been well described.

Objectives:

To analyze the echocardiographic parameters in PsA patients and to compare them with RA patients and controls.

Methods:

This cross-sectional, observational and comparative study, included thirty-six patients (nineteen in each group), aged 40-75 years, with PsA and RA who fulfilled the CASPAR (Classification criteria for Psoriatic Arthritis) and ACR/EULAR 2010 classification criteria, respectively, matched by age, gender and comorbidities with nineteen healthy controls. Exclusion criteria were a poor echocardiographic window, patients with a previous atherosclerotic cardiovascular disease (ischemic heart disease, cerebrovascular accident or peripheral arterial disease), and pregnancy. Transthoracic echocardiogram was performed and reviewed by 2 board-certified cardiologists, in all study subjects. Comparisons were done with X2, Kruskall Wallis or ANOVA.

Results:

There were not differences in the demographic characteristics between groups (Table 1). When comparing echocardiographic findings a statistically significant difference was found in the prevalence of diastolic dysfunction, being more prevalent in PsA and RA patients compared with controls (52.6% vs 52.6% vs 5.3%, p=0.002), likewise the presence of mild mitral valve regurgitation was higher (84.2% vs 53.6% vs 10.5%, p=0.001) and mild pulmonary valve regurgitation (68.4% vs 10.5% vs 0%, p=0.001). Prevalence of abnormal left ventricular geometry was higher in PsA and RA patients than controls (68.4% vs 63.2% vs 21.1%, p=0.006).

POS1402 HIGHER PREVALENCE OF SUBCLINICAL ATHEROSCLEROSIS IN PSORIATIC ARTHRITIS PATIENTS

Background:

Psoriatic arthritis (PsA) patients have a higher risk of developing a cardiovascular (CV) event than the general population due to an increased prevalence of traditional CV risk factors and to disease characteristics such as disease duration and activity. The carotid ultrasound (US) is a non-invasive diagnostic tool that can detect the presence of subclinical atherosclerosis which is directly associated with the risk of developing a CV event.

Objectives:

The aim of this study is to compare the prevalence of subclinical atherosclerosis detected by carotid US in PsA patients and controls.

Methods:

This is a cross-sectional, observational, and comparative study. A total of seventy-five PsA patients aged 40-75 years old, who fulfilled the 2006 CASPAR criteria and seventy-five matched controls by age (±5 years), gender and comorbidities were recruited for this study. Patients with history of a previous CV event and pregnant women were excluded from this study. A high-resolution B mode carotid US was performed in all study subjects by a certified radiologist. Subclinical atherosclerosis was defined as the presence of a carotid plaque (CP) or an increased carotid intima media thickness (cIMT). The presence of CP was defined as a cIMT ≥1.2mm or a focal narrowing ≥0.5mm in the surrounding lumen. An increased cIMT was considered as a value ≥0.8mm. Distribution was evaluated with the Kolmogorov-Smirnov test. Comparisons were done with χ2 test for qualitative variables and Student´s t test and Mann-Whitney’s U test for quantitative variables. A p value <0.05 was considered statistically significant.

Results:

There were no differences when comparing the demographic characteristics between both groups (Table 1). When comparing the carotid US findings, a statistically significant difference was found in the prevalence of CP, which was higher in the PsA group (44.0% vs 26.7%, p=0.026), in the presence of unilateral CP (25.3% vs 10.7%, p=0.019) and in the presence of subclinical atherosclerosis (52.0% vs 34.7%, p=0.032) (Figure 1).

Conclusion:

The prevalence of subclinical atherosclerosis was higher in PsA patients than controls, and this could be attributed to an increase in the inflammatory burden of these patients. The carotid US should be considered as part of the CV evaluation in all PsA patients, identifying those who would benefit from an opportune treatment preventing the development of a CV event.

AB0657 PERCEIVED STRESS AND FOOD INSECURITY IN PREGNANT AND POSTPARTUM WOMEN WITH RHEUMATIC DISEASES DURING THE COVID-19 PANDEMIC

Background:

The SARS-CoV-2 pandemic has directly impacted the psychological and physical health of individuals worldwide, as well as the global economy. Food insecurity rates have risen especially in vulnerable countries like Mexico. Furthermore, social isolation and economic uncertainty have multiplied depression and anxiety disorders. Pregnant and postpartum women are particularly vulnerable to food insecurity, increased stress, depression, and anxiety.

Objectives:

The aim of this study is to determine the perception of food insecurity (FI) and perceived stress in pregnant and postpartum women with rheumatic disease during the SARS-CoV-2 pandemic.

Methods:

An observational, cross-sectional and descriptive study was conducted. Patients from to the pregnancy and rheumatic diseases clinic of the University Hospital “Dr. José E. González” in Northeast Mexico evaluated between August to October 2020 were included. The Spanish validated versions of the Household Food Security Access Scale (HFIAS) and the Perceived Stress Scale (PSS-10) were applied by telephonic interview. The WHO recommendations were employed to determine the appropriate intake for each food group in a week. The Kolmogorov-Smirnov test was used to determine normality of the data. The Spearman correlation coefficient and the Kruskal-Wallis test were used for statistical analysis.

Results:

A total of 29 women were included. Six (20.6%) women were found to have moderate or severe degrees of food insecurity. In addition, 12 (40.30%) perceived moderate and severe levels of stress in the PSS-10. No relationship was found between food insecurity and perceived stress (p= 0.059). The food groups that exceeded the recommended weekly frequency were oils and sugars exceeded 3.9 and 2.9 frequencies, respectively.

Conclusion:

We found that 20.6% women suffered household food insecurity and 40.3% suffered moderate and severe levels of stress. No relationship was found between food insecurity with the HIFAS scale and perceived stress measures with the PSS-10. We found that oils and sugars exceeded more by the double of the recommended frequency per week.

AB0867-HPR VIOLENCE IN PREGNANT AND POSTPARTUM MEXICAN WOMEN WITH AUTOIMMUNE RHEUMATIC DISEASES

Background:

Gender violence is a prevalent issue worldwide. In Mexico, four out of ten women suffer any kind of violence. The factors that make women even more vulnerable to domestic violence are pregnancy, socioeconomic status, educational level, and the presence of chronic health problems. Violence represents a major risk factor for depression, anxiety, poor adherence to medical treatment, and obstetric adverse events.

Objectives:

The aim of this study is to determine the frequency of domestic violence in pregnant and postpartum women with autoimmune rheumatic diseases (ARD) and to compare with childbearing age women with ARD.

Methods:

Pregnant and postpartum women (PPW) with rheumatic disease evaluated at the Pregnancy and Rheumatic Diseases Clinic from the University Hospital “Dr. José E. González” in Monterrey, México from August to October 2020 were invited to participate. To compare, we enrolled childbearing age women with ARD without previous pregnancies. The Spanish validated version of the Hurt, Insulted, Threatened with Harm, Screamed scale (HITS) was applied via telephonic interview. The HITS scale evaluates in 4 questions the presence and frequency of violence by their intimate partners in the last 12 months. A score ≥ 10 points is considered as positive for violence.

Results:

A total of 48 women were included, 24 patients each group. The pregnant-postpartum group was divided in 6 (25) pregnant and 18 (75) postpartum women. Most of them were housewives (54.1%) with >10 years of education and with not formalized marital status 41% (common-law marriage). In the childbearing age group, most of them were employees (70.8), with >10 years of education with a current marital status of single (66.6%). The HITS scale was positive in the pregnant-postpartum group in 4 women (16.6%). Two of them had been victims of sexual assault and 2 reported physical/verbal violence. While in childbearing age group only 1 (4.16) reported physical/verbal violence.

Conclusion:

The 16% of the pregnant-postpartum group in our sample were suffering from domestic violence by their intimate partners, in contrast to the childbearing age group with only 1 patient reported violence. We found that postpartum and pregnancy women had more prevalence of violence. Screening for domestic violence followed by counseling and early referral are necessary to mitigate the physical and psychological consequences of domestic violence.

POS0491 LEFT VENTRICULAR GEOMETRIC ABNORMALITIES ASSOCIATED WITH HIGHER TITERS OF RHEUMATOID FACTOR AND ANTI-CYCLIC CITRULLINATED PEPTIDE ANTIBODIES IN RHEUMATOID ARTHRITIS PATIENTS

Background:

Rheumatoid arthritis (RA) patients have a higher risk of developing left ventricular (LV) geometric abnormalities which can result in the development of heart failure and cardiac death (1). High titers of rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies are associated with a worse cardiovascular (CV) prognosis in RA patients (2).

Objectives:

The aim of this study was to assess the association between RF and anti-CCP antibody titers, and the LV geometric abnormalities detected by a transthoracic echocardiogram.

Methods:

This was a cross-sectional, observational, and comparative study. Patients aged 40-75 years who fulfilled the 2010 ACR/EULAR classification criteria for RA underwent a transthoracic echocardiogram. Patients with RA and an alteration of LV geometry were matched to RA patients with normal LV geometry, by age, gender, comorbidities, and disease characteristics to eliminate confounders. LV geometry was evaluated with LV mass index and relative wall thickness. A blood sample was taken to measure RF and anti-CCP antibody titers. Distribution was evaluated with the Kolmogorov-Smirnov test. Comparisons were done with Chi square test for qualitative variables and Student’s t test and Mann-Whitney’s U test for quantitative variables. A p-value <0.05 was considered statistically significant.

Results:

A total of 82 RA patients were included in this study, 41 patients with altered LV geometry and 41 patients with normal LV geometry. Of the 41 patients with LV geometric abnormalities, 37 (90.2%) presented LV concentric remodeling and 4 (9.8%) presented LV concentric hypertrophy. We found no significant differences in the demographic and clinical characteristics between both groups (Table 1). Patients with altered LV geometry showed higher titers of IgA-RF (102.11 U/ml vs 21.70 U/ml, p=0.011) and anti-CCP antibodies (193.04 U/ml vs 18.29 U/ml, p=0.005) (Figure 1).

Conclusion:

RA patients with altered LV geometry had higher titers of IgA-RF and anti-CCP antibodies. This suggests an association between antibody titers and CV prognosis in RA patients. Rheumatologists should take these data into account when evaluating CV risk in RA patients, assessing the possibility of performing an echocardiogram for early detection of CV abnormalities and an opportune treatment in this group of patients.

Hyperkalemia influences the outcome of patients with cirrhosis with acute decompensation (AD) and acute-on-chronic liver failure (ACLF)

INTRODUCTION

The presence of hyperkalemia in different clinical scenarios has been described as a risk factor for mortality. Information about this electrolyte disorder in patients with cirrhosis is limited and there are no data in patients with acute-on-chronic liver failure (ACLF).

AIM

The aim of this study was to investigate whether hyperkalemia is a risk factor for mortality in patients with cirrhosis and acute decompensation (AD) with and without ACLF.

METHODS

We performed an analysis of the Chronic Liver Failure Consortium CANONIC database in 1,314 consecutive patients admitted to 29 European centers with AD both with and without associated ACLF (294 and 1020 respectively). Hyperkalemia was defined as serum potassium ≥ 5.0 mEq/L. All patients had at least one valid measure of serum potassium from admission and/or through the whole hospitalization.

RESULTS

1314 patients were admitted with AD and 294 of them had ACLF at admission. Prevalence of hyperkalemia was significantly higher in ACLF versus AD (22.4% and 8.6% respectively, p<0.001). Hyperkalemia was associated with an increased 90, 180 and 360-day mortality risk in ACLF compared to AD (HR 10 vs 2.3 at 90-day p<0.001, 8.9 vs 3.1 at 180-day, p<0.001 and 5.8 vs 3.8 at 360-day, p<0.001). In a multivariate analysis, the presence of hyperkalemia during admission was independently associated with 90-day mortality [HR 2.4 (1.7 - 3.4)]. Variability of potassium between two valid measures ≥ 0.9 mg/dl was always also associated with a higher mortality rate. Addition of hyperkalemia to MELD score (MELD-K model) improved the accuracy to predict 90-day mortality risk.

CONCLUSIONS

Hyperkalemia is an independent risk factor of mortality in patients with AD and ACLF. Addition of hyperkalemia to the MELD score improves diagnostic accuracy to predict 90-day mortality in patients with AD and ACLF.

AB0113 ANTI-CARBAMYLATED PROTEIN ANTIBODIES POSITIVITY AND DISEASE ACTIVITY IN HISPANIC PATIENTS WITH ESTABLISHED RHEUMATOID ARTHRITIS: AN OBSERVATIONAL STUDY

Background:

Clinically relevant anti-carbamylated (anti-CarP) antibodies are detected in up to 45% of rheumatoid arthritis (RA) patients and are associated with severe radiological progression, higher disease activity, and significantly more disability when studied in early phases of arthritis.

Objectives:

We aimed to determine the prevalence of anti-CarP antibodies in Mexican Hispanics with established RA and to assess their relationship with disease activity.

Methods:

A cohort study was conducted in 278 patients with established RA during an 18-month follow-up. We measured IgG/IgM/IgA rheumatoid factor (RF), IgG anticitrullinated protein antibodies (ACPA) and IgG/IgM/IgA anti-CarP antibodies using enzyme-linked immunosorbent assay (ELISA). For disease activity, we performed the 28-joint disease activity score with erythrocyte sedimentation rate (DAS28-ESR). Repeated measures one-way ANOVA was used to test the association between anti-CarP IgG antibody status and longitudinal DAS28-ESR scores. Patients were evaluated at baseline and at 6, 12, and 18 months during follow-up.

Results:

Anti-CarP IgG antibodies were positive in 47.8% of patients and, accounting for all isotypes, in 9.5% of patients with negative RF and ACPA. Triple antibody positivity was present in 42.6% of patients in our sample. Anti-CarP IgG antibody positivity did not show statistically significant differences in mean DAS28-ESR when compared to anti-CarP IgG antibody negative patients at baseline, 6, 12 or 18 months.

Conclusion:

Anti-CarP IgG antibodies are present in almost 50% of RA patients and, accounting for all isotypes, in 9% of RF and ACPA negative patients. Anti-CarP IgG antibody positivity was not associated to a higher disease activity measured by DAS28-ESR in Hispanic patients with established RA.

POS0552 DIASTOLIC DYSFUNCTION ASSOCIATED WITH INCREASED ACTIVITY IN RHEUMATOID ARTHRITIS

Background:

Cardiovascular disease (CVD) is the main cause of mortality in patients with rheumatoid arthritis (RA) reflected by a higher prevalence of cardiovascular risk factors (CVRFs), a chronic systemic inflammatory state and heart failure compared to the general population (1). Left ventricular diastolic dysfunction (LVDD) is attributable to structural abnormalities such as hypertrophy or interstitial fibrosis and impaired myocyte relaxation resulting from ischemia and is frequently asymptomatic (2). The presence of LVDD it could be considered as the first step to development of heart failure.

Objectives:

The aim of the study is to identify the association of disease activity and the presence of LVDD in patients with RA.

Methods:

A cross-sectional, observational, and comparative study of RA subjects that fulfilled ACR / EULAR 2010 classification criteria, aged 40-75 years. Subjects were evaluated by a transthoracic echocardiogram performed and reviewed by two certified echocardiographers. A total of fifty-one RA patients diagnosed with LVDD were included according to the 2016 American Society of Echocardiography (ASE). Distribution was evaluated with the Kolmogorov-Smirnov test. Descriptive analysis was done using measures of central tendency. Chi square, Student´s t test and Mann-Whitney U test were used for comparations between groups. A p value <0.05 was considered statistically significant.

Results:

We found no statistical difference between groups regarding age, gender, comorbidities (type 2 diabetes mellitus, hypertension, dyslipidemia and, active smoking) and body mass index. Patients with LVDD demonstrated a higher disease activity evaluated by disease activity score using 28 joints-C reactive protein (DAS28-PCR) (4.88 vs 3.56, p= 0.004) (Table 1). It was observed that patients with LVDD have a higher prevalence of being in the high disease activity category (41.2% vs. 13.7%, p= 0.002) (Figure 1). When performing a binary logistic regression, it was found that a high disease activity was the only independent predictor for the presence of LVDD, with an OR 4.70, (95% CI 1.63-13.50, p= 0.004).

Conclusion:

Patients with RA and LVDD have a higher disease activity, so emphasis should be placed on strict antirheumatic treatment and cardiovascular therapies to avoid the risk of developing CVD and the progression to heart failure. Logistic regression demonstrates that inadequate disease control is an independent factor from traditional CVRFs for the presence of LVDD.

POS0463 BEST CARDIOVASCULAR RISK CALCULATOR TO PREDICT ABNORMALITIES IN LEFT VENTRICULAR GEOMETRY IN RHEUMATOID ARTHRITIS

Background:

A relationship between rheumatoid arthritis (RA) and the presence of abnormalities in left ventricular (LV) geometry such as eccentric remodeling has recently been determined, even in the absence of cardiovascular risk factors and before clinical manifestations (1). The 2016 European League Against Rheumatism (EULAR) recommendations that cardiovascular (CV) risk prediction models should be adapted by a 1.5 multiplication factor in RA patients. Risk prediction algorithms based on the CV risk factors (CVRF) have been an important tool for adopting preventive measures and intensifying therapies based on the estimated risk but their application in predicting cardiac structural abnormalities has never been studied.

Objectives:

The aim of the study is to determine the CV risk calculator that best predicts alterations in ventricular geometry in RA.

Methods:

A cross-sectional, observational study of 108 RA patients between 40-75 years (ACR / EULAR 2010 classification criteria). The QRISK3, OMNIBUS, Framingham Risk Score Lipids (FRSL), Framingham Risk Score BMI (FRS-BMI) and Reynolds Risk Score (RRS) calculators were compared. The diagnostic performance was determined by ROC curves, and the discriminative capacity by the Area Under the Curve (AUC) 95% CI. The echocardiogram was the diagnostic gold standard. A p value <0.05 was considered statistically significant.

Results:

The prevalence of abnormalities in ventricular geometry was 38.9%. QRISK3 reported AUC of 0.656, 95% CI (0.550-0.762, p=0.006), cut-off point ≥4.6, sensitivity of 73.8% and specificity of 54.5%, and likelihood ratio of +1.62. FRS-BMI showed AUC of 0.653, 95% CI (0.543-0.762, p=0.008), cut-off point ≥11.02, sensitivity and specificity of 61.9% and 57.6% respectively, and likelihood ratio of +1.46. OMNIBUS showed AUC of 0.635, CI 95% (0.525-0.746, p=0.018), cut-off point ≥3.8, sensitivity and specificity of 57.1% and 68.2%. While RRS had AUC 0.644, 95% CI (0.534-0.755, p=0.012), cut-off point of 2.25, sensitivity of 47.6% and specificity 78.8%, and likelihood ratio of +2.24 (Figure 1 and Table 1).

Conclusion:

The QRISK3 calculator showed the highest discriminative ability and sensitivity to predict abnormalities in LV geometry. However, all calculators demonstrated the need for a lower cut-off point to predict alterations in ventricular geometry. Our findings require adequate reproducibility in other population groups to determine the applicability of CV risk algorithms as predictors of structural alteration of LV.

POS0482 WOOD SMOKE EXPOSURE IS ASSOCIATED WITH HIGHER ANTI-CCP ANTIBODY TITERS IN HISPANIC PATIENTS WITH RHEUMATOID ARTHRITIS

Background:

Wood smoke exposure is a risk factor for the development of chronic obstructive pulmonary disease (COPD), lung cancer and cardiovascular disease and it has also been linked to higher anti-CCP antibodies in patients with rheumatoid arthritis (RA) and COPD (1).

Objectives:

The objective of the present study is to report the correlation between anti-CCP, IgG, IgM and IgA rheumatoid factor (RF) to wood smoke exposure in patients with RA. Additionally, evaluate the impact of disease activity, biomass exposure, and disease duration on anti-CCP antibody levels.

Methods:

A cross-sectional, observational study was designed based on a cohort of Hispanic RA patients. All fulfilled the 2010 ACR/EULAR classification criteria for RA. Biomass smoke exposure was expressed using the biomass exposure index (BEI) calculated from the mean of exposed hours per day multiplied by the number of years exposed. Subjects were divided into two groups: those exposed to wood smoke with BEI ≥1 and subjects not exposed to wood smoke. They were matched by age, gender, and comorbidities. Anti-CCP antibodies and RF were measured by ELISA with cutoff points of <5 U/mL and <20 U/mL respectively.

Results:

A total of 318 subjects were included, 159 (50%) of them had a history of exposure to wood smoke. Anti-CCP antibody positivity was present in 102 (64.2%) with a median titer of 97.1 U/mL (1.7-198) in the RA exposed group, and in 89 (56%) with a median titer of 8.5 U/mL (1.1-145) in the RA non-exposed group. A significant difference was found in anti-CCP antibody titers between groups (p=0.003). (Table 1). Spearman’s rho showed a small but statistically significant correlation between BEI and anti-CCP antibody titers (rho= 0.170, p=0.002). Biomass exposure was independently related to higher anti-CCP antibody titers (B=35.4, p<0.001).

Conclusion:

RA patients who were exposed to wood smoke had higher titers of anti-CCP antibodies than non-exposed RA patients. Furthermore, biomass exposure was shown to be independently related to higher titers of anti-CCP antibodies.

POS1220 PREGNANT AND POSTPARTUM WOMEN WITH AUTOIMMUNE RHEUMATIC DISEASES AND COVID-19: A CASE SERIES

Background:

Pregnant women represent a high-risk population during the COVID-19 pandemic. The main cause of maternal deaths in Mexico during 2020 was COVID-19 with 191 (21.2%) deaths registered until December 2020. The age group most affected was 30 to 34 years. Women during their third trimester and during puerperium were the most affected. Information regarding pregnant and postpartum women with autoimmune rheumatic diseases remains scarce.

Objectives:

The aim of this study was to describe a COVID-19 case series from a clinic of pregnancy and rheumatic diseases.

Methods:

We conducted a descriptive, retrospective study in patients from the clinic of pregnancy and rheumatic diseases of the University Hospital “Dr. Jose Eleuterio Gonzalez” in Monterrey, Mexico. Pregnant patients with RD and documented COVID-19 between March and November 2020 were included. Demographic and clinical features were obtained. Results are shown in descriptive statistics.

Results:

From the 18 women with autoimmune rheumatic disease in follow-up during this period, 2 (11.1%) pregnant women, 2 (11.1%) postpartum women, and 1(5.5%) post-miscarriage woman developed COVID-19. The mean age was 28 ± 6.3 years, 3 (60%) had systemic lupus erythematosus, 1 (20%) had rheumatoid arthritis, and 1 (20%) had the antiphospholipid syndrome. Clinical features and treatments are shown in Graphic 1 and Table 1. The most frequent symptoms were fever (80%), cough (60%) and anosmia (60%). Four (80%) had mild symptoms, and 1 (20%) had severe symptoms requiring intensive care unit admission and mechanical ventilation. Three (60%) referred history of contact with a person who had COVID-19. All the patients were using hydroxychloroquine and prednisone. No patient in our study died.

Conclusion:

From our population, a total of 27.8% presented COVID-19. Most of our patients had a mild course of SARS-CoV-2 infection consistent with data from the general population. Additionally, none of our patients had risk factors such as hypertension, diabetes, chronic kidney disease or lung disease. Nonetheless, pregnant women remain a vulnerable population. Prevention measures must continue worldwide to avoid additional COVID-19 morbidity and mortality.

AB0329 HIGHER PREVALENCE OF ECHOCARDIOGRAPHIC ABNORMALITIES IN PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS

Background:

Systemic lupus erythematosus (SLE) is a chronic, inflammatory, and autoimmune disease that damages vital organs such as the heart. Patients with SLE have a higher risk of developing a cardiovascular (CV) disease than the general population (1).

Objectives:

The aim of this study was to compare the echocardiographic findings in patients with SLE and controls.

Methods:

This was a cross-sectional, observational, and comparative study. A total of 38 patients with SLE according to the 2019 EULAR/ACR classification criteria, ≥18 years old and 38 matched controls by age (±5 years) and gender, were recruited for this study. Exclusion criteria were a poor echocardiographic window, patients with a previous CV event, such as myocardial infarction, cerebrovascular event or peripheral arterial disease, and pregnant women. A transthoracic echocardiogram, including speckle tracking technique, was performed, by two certified echocardiographers, in all study subjects. Distribution was evaluated with Kolmogorov-Smirnov test. Comparisons were done with χ2 and Fisher´s Exact test for qualitative variables, and Student’s t test and Mann-Whitney´s U test for quantitative variables. A p-value <0.05 was considered statistically significant.

Results:

When comparing demographic characteristics there were no significant differences in age, gender, and comorbidities between SLE patients and controls. In the echocardiographic findings a significant difference was found in the left ventricular ejection fraction (LVEF), lower in SLE patients compared to controls (57.02% vs 61.89%, p=0.001), in the global longitudinal strain (GLS), reduced in SLE patients (-19.55% vs -22.00%, p=0.001), in the tricuspid annular plane systolic excursion (TAPSE), lower in SLE patients (22.00mm vs 24.00mm, p=0.011), in the left atrial volume index, higher in SLE patients (28.44ml/m2 vs 22.29ml/m2, p=0.014) and in the presence of mitral regurgitation, more prevalent in SLE patients (31.6% vs 10.5%, p=0.024) (Table 1).

Conclusion:

Patients with SLE have a worse left ventricular function, evaluated by LVEF and GLS, a worse right ventricular systolic function, evaluated by TAPSE, an increased left atrial volume index and a higher prevalence of mitral regurgitation, which are associated with a higher risk of CV death. It is important to consider including a transthoracic echocardiogram as part of the CV evaluation in patients with SLE, which may result in an early detection of CV abnormalities and an opportune treatment.

POS0562 PULSE PRESSURE AS AN INDICATOR OF SUBCLINICAL ATHEROSCLEROSIS IN RHEUMATOID ARTHRITIS

Background:

Pulse pressure (PP) is defined as the difference between systolic and diastolic blood pressure and represents arterial compliance and reflective properties of blood flow (1). It is well known that gender, age, and race / ethnicity are intrinsic factors of the patient that influence PP. Brachial PP has recently been associated with markers of subclinical cardiovascular disease after adjustment with traditional cardiovascular risk factors in the general population (2). However, this relationship has not been studied in patients with rheumatoid arthritis (RA) and its identification would allow earlier adjustments of cardiovascular therapies in this high-risk group.

Objectives:

The aim of the study is to analyze the difference in PP between patients with RA and healthy controls. Additionally, to analyze the difference between patients with carotid plaque (CP) and without CP.

Methods:

A cross-sectional, observational, and comparative study of ninety-two patients with RA aged 40-75 years and who fulfilled ACR/EULAR 2010 classification criteria. Also, we included ninety-two controls without RA, matched by gender, age and comorbidities. A carotid ultrasound was performed in patients with RA and it was divided into two subgroups, with the presence of CP and without CP. A blood pressure measurement was taken after 15 minutes of rest on the right arm of all patients. Distribution was evaluated with the Kolmogorov-Smirnov test. Descriptive analysis was done using measures of central tendency. Chi square, Student’s t test and Mann-Whitney U test were used for comparations between groups. A p value <0.05 was considered statistically significant.

Results:

We found no statistical difference between groups regarding age, gender and, comorbidities (type 2 diabetes mellitus, hypertension, dyslipidemia and, active smoking) (Table 1). There was a significant difference in PP between patients with RA and controls (50 mmHg vs 41 mmHg respectively, p = 0.032). Patients with RA had a significant difference in PP of patients with CP and without CP (50 mmHg vs 44 mmHg respectively, p = 0.008) (Figure 1). When performing a binary logistic regression, it was found that PP was the only independent factor for the presence of CP in patients with RA, OR 1.054 (95% CI 1.008-1.101, p = 0.020).

Conclusion:

Patients with RA had a higher PP than controls. Binary logistic regression showed PP as the only independent factor for the presence of subclinical atherosclerosis in patients with RA. PP is a parameter that all rheumatologists should consider when evaluating cardiovascular risk in patients with RA.

POS0553 IMPACT OF RHEUMATOID ARTHRITIS ON LEFT VENTRICULAR REMODELING

Background:

Patients with Rheumatoid Arthritis (RA) have a higher prevalence of cardiovascular diseases (1) and a strong association with abnormalities in the left ventricle (LV) geometry. Both concentric and eccentric remodeling have been determined as an independent factor for sudden cardiac arrest in the general population with normal or slightly decreased ventricular function (2) but there is still controversy about the factors involved and the pathophysiology in patients with RA.

Objectives:

The aim of the study is to determine the characteristics of LV geometry and the impact of RA.

Methods:

A cross-sectional, observational, and comparative study of fifty-two RA patients that fulfilled ACR / EULAR 2010 classification criteria, aged 40-75 years. Controls were included and matched by age, gender, and comorbidities. Subjects were evaluated using a transthoracic echocardiogram performed and reviewed by two certified echocardiographers. Ventricular geometry was evaluated with indexed left ventricular mass and relative wall thickness. Distribution was evaluated with the Kolmogorov-Smirnov test. Descriptive analysis was done using measures of central tendency. Chi square, Student’s t test and Mann-Whitney U test were used for comparations between groups. A logistic binary regression was performed with the traditional cardiovascular risk factors (CVRFs), age and RA diagnosis. A p value <0.05 was considered statistically significant.

Results:

No significant differences were found in the traditional CVRFs (type 2 diabetes mellitus, dyslipidemia, active smoking, and hypertension) (Table 1). Most of the subjects reported normal geometry in both groups (55.8% for RA group vs 64.0% for controls). A higher prevalence of eccentric hypertrophy was found in the RA group, 13 (25%) subjects versus 3 (6%) in the control group, p = 0.009. The binary regression showed that the diagnosis of RA was the only independent risk factor for the presence of eccentric hypertrophy, OR 7.22 95% CI (1.68-31.02, p = 0.008).

Conclusion:

There is a higher prevalence of eccentric remodeling in patients with RA independently of traditional CVRF. The diagnosis of RA is an independent risk factor for the presence of eccentric hypertrophy that is associated with higher mortality. Treatment of cardiovascular comorbidities should be intensified in those patients with abnormalities in LV geometry in order to prevent cardiovascular diseases such as heart failure.

AB0658 FEAR OF COVID-19 IN POSTPARTUM WOMEN WITH RHEUMATIC DISEASE

Background:

In Mexico, the SARS-CoV-2 pandemic has totaled almost two million cases and exceeded 150,000 deaths (29/01/2021). Currently, COVID-19 has become the leading cause of death in pregnant women in Mexico. COVID-19 has additionally impacted the psychological health of individuals including women with rheumatic diseases.

Objectives:

The aim of this study is to compare the Fear of COVID-19 Scale (FCV-19S) in postpartum women with and without autoimmune rheumatic diseases.

Methods:

A cross-sectional, descriptive, and comparative study was conducted. The Spanish FCV-19S version was applied by telephone or e-mail. The instrument consists of seven items, each with a five-point Likert scale of options. The participant must choose the options that best represent their perception about the statements presented. The maximum possible total is 35 points. Sociodemographic information was collected from the clinical charts. The Kolmogorov-Smirnov test was used to determine normality of the data. Statistical analysis was done using the Mann-Whitney U test.

Results:

Forty-four postpartum women were included (22 from the Pregnancy and Rheumatic Diseases Clinic and 22 from the Obstetrics Department, both groups from the University Hospital “Dr. José E. González in Monterrey, México). The mean level of fear found in women with rheumatic disease was 16 (6.6) points versus 14 (4.6) points in the non-rheumatic patients group. No significant difference was found between groups (p=0.65). Regarding the rheumatic diseases group, women in the category of other diagnoses (that included Sjögren’s Syndrome, antiphospholipid syndrome, and dermatomyositis) had a greater mean FCV-19S score (20.2), than patients with systemic lupus erythematosus (17.3) and rheumatoid arthritis (15.4).

Conclusion:

Women with postpartum rheumatic disease had a higher FCV-19S score than postpartum women without rheumatic diseases, although this difference was not statistically significant.

Self-Tuning Extended Kalman Filter Parameters to Identify Ankle's Third-Order Mechanics

The estimation of human ankle's mechanical impedance is an important tool for modeling human balance. This work presents the implementation of a parameter-estimation approach based on a state-augmented extended Kalman filter (AEKF) to infer the ankle's mechanical impedance during quiet standing. However, the AEKF filter is sensitive to the initialization of the noise covariance matrices. In order to avoid a time-consuming trial-and-error method and to obtain a better estimation performance, a genetic algorithm (GA) is proposed to best tune the measurement noise (Rk) and process noise covariances (Q) of the extended Kalman filter (EKF). Results using simulated data show the efficacy of the proposed algorithm for parameter-estimation of a third-order biomechanical model. Experimental validation of these results is also presented. They suggest that age is an influencing factor in the human balance.

Colon capsule endoscopy versus CT colonography in FIT-positive colorectal cancer screening subjects: a prospective randomised trial-the VICOCA study

BACKGROUND

Colon capsule endoscopy (CCE) and CT colonography (CTC) are minimally invasive techniques for colorectal cancer (CRC) screening. Our objective is to compare CCE and CTC for the identification of patients with colorectal neoplasia among participants in a CRC screening programme with positive faecal immunochemical test (FIT). Primary outcome was to compare the performance of CCE and CTC in detecting patients with neoplastic lesions.

METHODS

The VICOCA study is a prospective, single-centre, randomised trial conducted from March 2014 to May 2016; 662 individuals were invited and 349 were randomised to CCE or CTC before colonoscopy. Endoscopists were blinded to the results of CCE and CTC.

RESULTS

Three hundred forty-nine individuals were included: 173 in the CCE group and 176 in the CTC group. Two hundred ninety individuals agreed to participate: 147 in the CCE group and 143 in the CTC group. In the intention-to-screen analysis, sensitivity, specificity and positive and negative predictive values for the identification of individuals with colorectal neoplasia were 98.1%, 76.6%, 93.7% and 92.0% in the CCE group and 64.9%, 95.7%, 96.8% and 57.7% in the CTC group. In terms of detecting significant neoplastic lesions, the sensitivity of CCE and CTC was 96.1% and 79.3%, respectively. Detection rate for advanced colorectal neoplasm was higher in the CCE group than in the CTC group (100% and 93.1%, respectively; RR = 1.07; p = 0.08). Both CCE and CTC identified all patients with cancer. CCE detected more patients with any lesion than CTC (98.6% and 81.0%, respectively; RR = 1.22; p = 0.002).

CONCLUSION

Although both techniques seem to be similar in detecting patients with advanced colorectal neoplasms, CCE is more sensitive for the detection of any neoplastic lesion.
