Haemophagocytic lymphohistiocytosis after intravesical BCG administration for bladder cancer presenting with multiorgan failure

Bacillus Calmette-Guérin (BCG), is administered intravesically as an adjuvant immunotherapy for the treatment of non-muscle invasive bladder cancer. While mild non-infectious problems can occur in up to 85 % of cases, significant local and systemic complications have been reported in 1-5 % of cases. We report the case of a patient with superficial bladder cancer who developed multiorgan failure after intravesical BCG instillation including the kidney and liver with subsequent haemophagocytic lymphohistiocytosis. Our case illustrates the first reported combination of secondary haemophagocytic lymphohistiocytosis with severe renal and liver failure after BCG immunotherapy for bladder carcinoma. Treatment strategy is discussed.

POS0832 MORTALITY TRENDS IN ANCA-ASSOCIATED VASCULITIDES (AAVs): DATA FROM A CONTEMPORARY, MULTICENTER ANCA REGISTRY

Background

AAVs are a group of rheumatic diseases with excess morbidity and mortality (~3-fold higher compared to the general population). Long-term studies looking at mortality trends in contemporary patient cohorts are limited.

Objectives

To investigate the overall long-term survival and all-cause mortality in a contemporary AAV patient cohort.

Methods

Multicenter cohort study of patients registered and prospectively followed in the Greek ANCA Registry.

Results

Data for 165 patients (989.38 patient-years of follow up) with a diagnosis of AAV (GPA n=95, 58%, MPA n=54, 33%, EGPA n=16, 9%) were analyzed (January 1, 1998 - January 10, 2022). 53% of patients were female, with a mean age of 65 (±16.4) years; the majority (97%) had generalized disease and were ANCA positive (76%). The mean follow-up since diagnosis was 5.9 (±5.1) years. At the end of follow-up, the overall mortality rate was 20% (33/165), whereas the cumulative mortality rates at 5 and 10 years were 24% and 26% respectively. Overall cumulative survival at 5 years was worse in patients with MPA (57%) compared to GPA (81%) and EGPA (92%), (p<0.001). There was no difference in long-term survival among those treated with different induction regimens including cyclophosphamide (CYC, n of deaths=24/83, 28.9%), rituximab (RTX, n=4/40, 10%) or the CYC+RTX combination (n=3/16, 18.7%). Furthermore, there was no difference in survival between relapsing (≥1 relapses) and non-relapsing (n=76) patients (Figure 1). Cumulative survival was worse in patients who initially presented with lung (66% vs. 90% at 5 years, p=0.007), kidney (56% vs. 96% at 5 years, p<0.001) and simultaneous lung and kidney (39% vs. 93% at 5 years, p<0.001) involvement. Among the 33 registered deaths, the most frequent causes were infections (52%), followed by cardiovascular events (24%), disease flares (14%) and malignancies (10%).

Figure 1.

Conclusion

In a contemporary multi-center AAV cohort, the cumulative mortality rates at 5 and 10 years were 24% and 26% respectively. Overall survival was worse in patients with MPA as well as those with combined lung and kidney involvement at baseline while there were no survival differences according to the initial induction regimen. Infection was the most common cause of death. These findings emphasize the unmet needs for better, less toxic therapies.

AB0633 Health-Related Quality of Life in ANCA Vasculitides and Rheumatoid Arthritis patients: a cross-sectional comparative study

Background

ANCA associated vasculitides (AAVs) are rare, serious forms of vasculitides. There are limited data regarding the quality of life in patients with AAVs compared to other chronic inflammatory diseases.

Objectives

The purpose of this study was to compare the quality of life between patients with AAV and those with a chronic inflammatory arthritis such as rheumatoid arthritis (RA).

Methods

Multicenter, cross-sectional study of AAV and RA patients followed in three tertiary referral centers. Data from 1007 healthy controls served as historic controls.1 HRQoL was assessed with the Short Form 36 Health Survey (SF-36) which includes physical and mental component summary scores (PCS and MCS). Disease activity were assessed with the Birmingham Vasculitis Activity Score version 3 (BVAS 3, for AAVs) and the DAS28-ESR (for RA) respectively and organ damage/function with the Vasculitis Damage Index (VDI for AAVs) score and Health Assessment Questionnaire (HAQ for RA) scores, respectively.

Results

66 patients with AAVs (GPA 62%, MPA 29% and EGPA 9%, females 56%, mean age 63.4 years, generalized disease 74%, mean disease duration 6.2 years, remission 73%) and 71 with RA (females 56%, mean age 63.3 years, remission 72%) were included. Both AAV and RA patients had significantly lower PCS and MCS scores compared to healthy controls (p < 0.05) while RA patients had lower PCS and MCS scores compared to AAV patients (p < 0.05). According to disease activity status, there was no difference in the SF-36 scores between those with active (BVAS > 1) and inactive (BVAS < 1) AAV, except for the energy-fatigue component (55.0 ± 21.8 vs. 67.2 ± 20.7, p= 0.038) whereas patients with active RA (DAS28-ESR > 3.2) had lower scores for all SF36 components compared to those with low disease activity (DAS28-ESR < 3.2). Additionally, active RA patients had lower both PCS and MCS scores compared to active AAV patients (p < 0.05). AAV patients with increased damage scores (VDI > 3) had lower PCS score compared to those with less organ damage (VDI < 3), (33.9 ± 10.1 vs. 49.1 ± 10.2, p < 0.001) while RA patients with increased damage/poor functionality (HAQ ≥ 0.75) had lower both PCS and MCS scores compared to those with less damage (HAQ ≤ 0.63), (35.0 ± 7.2 vs. 48.4 ± 8.6, p < 0.001) and (40.5 ± 8.6 vs. 48.2 ± 7.6, p < 0.001 respectively). Compared to patients with AAV, RA patients with increased damage had lower score for the pain component compared to AAV patients (37.7 ± 28.6 vs. 61.2 ± 29.5, p= 0.024).

Conclusion

In general, patients with AAV and RA, demonstrate impaired quality of life compared to healthy controls. In the AAV group, quality of life correlated more with organ damage and less with disease activity whereas in RA patients, quality of life correlated both with disease activity and damage. These data emphasize the need for more efficacious therapies for AAV patients that could prevent chronic organ damage and improve quality of life.

Deformation analysis in post-hospitalised patients with moderate SARS-CoV-2 infection

Funding Acknowledgements

Type of funding sources: None.

Background

SARS-CoV-2 infection is associated with multiple cardiac manifestations (1,2). Global longitudinal strain (GLS) by speckle tracking echocardiography (STE) is a novel transthoracic echocardiography (TTE) measure of myocardial deformation, which could early recognize subclinical cardiac injury in COVID-19 patients (3,4).

Purpose

We aimed to explore GLS profiles in post-hospitalized COVID-19 patients to identify features of eventual subclinical cardiac injury and to investigate the possible correlation with the severity of infection.

Methods

We enrolled 33 patients (mean age 59.2 ± 13, 64% men) with positive SARS-CoV-2 RT-PCR, hospitalized for moderate COVID-19 disease, with no admission to intensive care unit. Patients were submitted to TTE 1-2 months after discharge.  Images were anonymised and analysed offline by two accredited cardiologists. Clinical parameters and laboratory findings from hospitalization were also collected.  Acute myocardial infarction and pulmonary embolism were exclusion criteria.

Results

Mean duration of hospitalization was 12.9 ± 8.0 days. Study population had normal systolic function with a mean LV ejection fraction 58.6% (±3.6) while the majority of patients had relative low values of LV global longitudinal strain, mean 15.2% (±2.3). Arterial hypertension was present in 51.5% of patients and a history of previous myocardial infarction was referred in 6.1% of the population. Only 24.2% of patients had elevated troponin levels during the previous in-hospital period (mean maximal value of hs-troponin  was 18.1 ±16.6 pg/mL) whereas  81.8% had abnormal D-Dimers values (mean 2424 μg /L, range ±2825) and 93.1% had high hs-CRP values (138.2 ±92.0 mg/L) . Duration of hospitalization had strong significant correlation with D-Dimers (rho: 0.708, p: &lt;0.001) and hs CRP (rho:0383, p:0.028) and  marginal association with troponin ( rho: 0.335, p:0.056). Moreover, global longitudinal strain showed significant association with duration of hospitalization (rho:-0.545, p: 0.007). Traditional systolic indices as LVEF and the various diastolic parameters  showed no significant association with severity of disease reflected by the duration of hospitalization and the other clinical and laboratory biomarkers.

Conclusion

Cardiac manifestations of SARS-CoV-2 infections could be present in mild to moderate disease and seems to associate with the severity of infection. The novel echocardiographic parameters such as GLS could add valuable information and identify  possible subclinical cardiac injury often unrecognized by traditional TTE examination.

Development of a risk-score for pericarditis recurrence in patients with a first episode of acute pericarditis

Background/Introduction

Currently we remain uncertain about which patients are at increased risk for recurrent pericarditis.

Purpose

We developed a risk score for pericarditis recurrence in patients with acute pericarditis.

Methods

We prospectively recruited 262 patients with acute pericarditis. Patients' demographics, clinical, imaging and laboratory data at presentation, were collected. Patients were followed-up for a median of 51 months (interquartile range 21–71) for recurrence. Variables with &lt;10% missingness were entered into multivariable logistic regression models with stepwise elimination to explore independent predictors of recurrence. The performance of the final model was assessed by the c-index and model's calibration and the optimism corrected c-index were evaluated after 10-fold cross-validation.

Results

We identified six independent predictors for pericarditis recurrence i.e., age, effusion size, platelet count (negative predictors) and reduced inferior vena cava collapse, in-hospital use of corticosteroids, and heart rate (positive predictors). The final model had good performance for recurrence, c-index 0.783 (95% CI 0.725–0.842), while the optimism corrected c-index after cross-validation was 0.752. Based on these variables we developed a risk score point system for recurrence (0–22 points) with equally good performance (c-index 0.740, 95% CI 0.677–0.803). Patients with a low score (0–7 points) had 21.3% risk for recurrence, while those with high score (≥12 points) had a 69.8% risk for recurrence (Figure 1). The score was predictive of recurrence among most patient subgroups.

Conclusions

A simple risk score point system based on 6 variables can be used to predict the individualized risk for pericarditis recurrence among patients with a first episode of acute pericarditis.

AB0543 CHARACTERISTICS AND TREATMENT CHANGES IN PATIENTS WITH PSORIATIC ARTHRITIS SEEN IN A COMBINED DERMATOLOGY-RHEUMATOLOGY CLINIC

Background:

Data on patients with Psoriasis (PSO) referred to a combined Dermatology-Rheumatology outpatient Clinic (Derm-Rheum) with suspected psoriatic arthritis (PsA) are limited.

Objectives:

To assess patient characteristics and treatment changes in PsA patients referred to a Derm-Rheum Clinic.

Methods:

Prospective study of PSO patients referred to a combined Derm - Rheum Clinic from February 2018 to June 2020 in a Tertiary University Hospital.

Results:

Among 151 patients with PSO referred to the Clinic, 129 (85%) with a final diagnosis of PsA were included. In 73% of patients (n=94) PsA was diagnosed there for the 1st time. 56% were females with a mean age of 55 years and a median disease duration of 14.2 years. At initial evaluation, 95% had peripheral arthritis, 45% nail involvement, 23% axial involvement, 12% enthesitis and 6% dactylitis with a median DAPSA score of 20.5 and PASI score of 1.6, respectively. 31% of the patients were not receiving any systemic treatment, 45% were on biologics (30% as monotherapy, 15% in combination with non-biologics), 29% were on non-biologics (14% as monotherapy, 15% in combination with biologics or targeted synthetic agents] and 10% were on targeted synthetic (ts) agents. At last visit (median follow-up: 15 months) only 8% did not receive any systemic therapy (p<0.001 compared to 1st visit), 62% were on biologics (39% monotherapy – 23% in combination with non-biologics, p=0.009), 46% were on non-biologics (20% as monotherapy – 26% in combination with biologics or ts agents, p=0.01) and 10% of the patients were on apremilast. The median DAPSA and PASI scores at last visit were 5.3 and 0, respectively.

Conclusion:

About 2/3 of patients with PSO referred to a combined Derm - Rheum Clinic with suspicious musculoskeletal complaints were diagnosed for the 1st time as PsA. During follow-up the percentage of PsA patients who started or continued systemic therapy significantly increased with significant improvement of disease activity indices. These data emphasize the value of combined Derm - Rheum Clinics for earlier diagnosis and more efficacious treatment of PsA patients.

AB0537 PSORIATIC ARTHRITIS BURDEN, QUALITY OF LIFE AND FUNCTIONAL ABILITY IMPAIRMENTS IN PATIENTS INITIATED ON APREMILAST IN THE ROUTINE CARE IN GREECE: INTERIM RESULTS FROM THE MULTICENTER PROSPECTIVE STUDY “APROACH”

Background:

Psoriatic arthritis (PsA) is a chronic inflammatory disease associated with substantial psychosocial burden and health-related quality of life (HRQoL) and functional ability impairments.

Objectives:

To characterize the profile of patients with PsA initiating therapy with apremilast in routine care settings, in terms of the physician-assessed clinical disease burden and the patient-reported generic and disease-related HRQoL and functional disability.

Methods:

This is an ongoing 52-week multicenter, prospective study conducted in the Greek healthcare environment. Eligible patients are bio-naïve adults with active peripheral PsA, inadequate (within the first 12 months of treatment) response/intolerance to a prior conventional synthetic disease-modifying antirheumatic drug (csDMARD), and no prior use of tofacitinib, initiating apremilast as per the approved label. Data are being collected by physician assessments, as performed in routine clinical practice, and by patient-reported outcomes. 170 patients enrolled in the study; data at apremilast initiation (baseline) from the first 100 eligible consenting patients are presented in this interim analysis as per protocol.

Results:

99 evaluable patients were consecutively enrolled in 19 rheumatology departments between 15-Apr-2019 and 13-Jan-2020. At baseline (Table 1) [mean (SD) age: 53.8 (11.7) years], 43.4% of the patients had at least one (30.3% had ≥2) ongoing comorbidity other than PsA/PSO. The median [interquartile range (IQR)] PsA and psoriasis duration were 1.9 (1.0-3.5) and 7.5 (3.9-16.8) years, respectively. All subjects were on csDMARD while 24.2% received combination therapy, oral non-steroid anti-inflammatory drugs (32.3%), topical treatments (20.2%) and systemic steroids (11.1%). Based on the Clinical Disease Activity in PsA (cDAPSA) score, 58.6% of the patients had moderate, and 29.3% high disease activity. In the EuroQol (EQ) 5-Dimensions (5D) 5-Levels questionnaire, 93.9, 82.8, 82.8, 73.7, and 51.5% of the patients reported problems in ‘pain/discomfort’, ‘anxiety/depression’, ‘usual activities’, ‘mobility’, and ‘self-care’, respectively. The median (IQR) baseline UK-weighted EQ-5D index and EQ-Visual Analogue Scale scores were 0.55 (0.44-0.70) and 50.0 (40.0-70.0), respectively. The median (IQR) Health Assessment Questionnaire-Disability Index (HAQ-DI) and mean (SD) PsA Impact of Disease 12-item (PsAID12) scores were 1.0 (0.5-1.4) and 4.6 (2.0), respectively.

Conclusion:

More than 8 out of 10 bio-naïve patients initiated on apremilast in the routine clinical care in Greece have at least moderate disease activity, active psoriasis, and problems with pain/discomfort, anxiety/depression, and performance of usual activities at a median of 2 years post-diagnosis. HAQ-DI and PsAID12 scores indicate moderate impairment of physical functionality and PsA-related HRQoL. The findings underscore considerable disease burden early in the disease course.

Outcome of refractory to conventional and/or biologic treatment adult Still's disease following canakinumab treatment: Countrywide data in 50 patients

OBJECTIVE

To assess the efficacy and safety of the IL-1b inhibitor canakinumab in all adults with refractory Still's disease identified from the National Organization For Medicines for off-label drug use.

METHODS

In a retrospective longitudinal multicenter cohort of 50 patients (median age 39 years) with active Still's disease despite treatment with corticosteroids (n = 11), conventional and synthetic (n = 34) and/or biologic disease modifying anti-rheumatic drugs (n = 30), we assessed the efficacy of canakinumab 150-300 mg administered every 4 (n = 47) or 8 weeks (n = 3) as combination therapy or monotherapy (n = 7) during a median follow-up of 27 (3-84) months.

RESULTS

Α complete response was initially observed in 78% of patients within 3 months (median), irrespective of age at disease onset. A partial response was evident in 20%. One patient had resistant disease. Treatment de-escalation was attempted in 15 of 39 complete responders and a complete drug discontinuation in 21 patients for 8 months (median). Eleven patients (22%) relapsed during treatment, one during de-escalation process, and 11 after treatment discontinuation. Overall, 9 of 11 relapses were successfully treated with canakinumab treatment intensification or re-introduction. At last visit, 18% of patients were off treatment due to remission and 26% due to disease activity. Canakinumab had a significant corticosteroid sparing effect allowing weaning in 21 of 41 cases. Infections (20%, severe 4%) and leucopenia (6%) led to treatment cessation in one patient.

CONCLUSION

High rates of sustained remission were observed in this, largest so far, real-life cohort of adult patients with refractory Still's disease treated with canakinumab.

Hydroxychloroquine for colchicine-resistant glucocorticoid-dependent idiopathic recurrent pericarditis: an observational prospective study

Background

Glucocorticoid (GC)-dependent, colchicine-resistant idiopathic recurrent pericarditis (IRP) remains a clinical challenge. We assessed for the first time the efficacy and safety of hydroxychloroquine (HCQ) in IRP.

Methods

This is a single center, post hoc analysis of prospectively collected data of 15 patients with refractory to standard therapy (colchicine plus either GC or anakinra) IRP (≥3 recurrences, disease duration ≥12 months and inability to wean off treatment) treated with HCQ (400 mg/day). These patients were matched 1:1 for age, sex, and treatment type to IRP patients receiving standard-of-care treatment (control group, n=15). Pericarditis recurrence, the time and C-reactive protein (CRP) levels at 1st flare, the % of patients able to achieve a ≥50% reduction of baseline GC dose and the % reduction of GC dose were compared between groups.

Results

Almost all patients (n=29) but one in the HCQ group (14/15) relapsed during follow-up. However, HCQ treatment was associated with an increased median time of flare-free survival (increase by 4 weeks compared to controls) and reduced hazard ratio for flare in survival analysis (HR=0.36, 95% CI 0.16–0.77, p=0.009). HCQ was also associated with a higher proportion of patients obtaining a ≥50% dose reduction of GCs (33.3% vs. 0% in the control group, p=0.037) and reduced GC dose (HCQ: −43.5% vs. control: −4.5%, p&lt;0.001). There were no signficant differences in CRP levels at flare between groups (p=0.615).

Conclusions

In this prospective study, HCQ use was associated with a GC-sparing effect and an increased flare-free survival period in patients with colchicine resistant GC-dependent IRP.

FRI0493 THE INTERLEUKIN-1B INHIBITOR CANAKINUMAB FOR REFRACTORY STILL’S DISEASE: LONG-TERM EXPERIENCE IN 50 CONSECUTIVE PATIENTS

Background:

Interleukin-1 (IL-1) is a major mediator of the inflammatory cascade in Still’s disease and an established therapeutic target.

Objectives:

To assess the efficacy and safety of the IL-1b inhibitor canakinumab in adolescent and adult patients with refractory Still’s disease.

Methods:

We conducted a retrospective longitudinal outcome study of 50 consecutive patients aged 39 years (median, range 14-72), fulfilling the Yamaguchi disease classification criteria, with active disease despite treatment with corticosteroids (CS) (n=11) and/or methotrexate (n=9) and/or biologics (n=30) [tumor necrosis factor inhibitors (n=13), IL-6 blockade (n=7), abatacept (n=2), anakinra (n=24); ≥1 biologics (n=13)]. Canakinumab 150-300 mg was administered sc, starting every 4 (n=48) or 8 weeks (n=2), for a median of 24 months (range 3-84). Concomitant treatment included CS (n=41), methotrexate (n=12) and leflunomide (n=3).

Results:

Complete remission was initially achieved in 78% of patients within a median time of 3 months, irrespective of age at disease onset. Partial clinical and laboratory response was evident in 20%. Canakinumab was discontinued in one patient with resistant disease (primary failure) and in 6 out of 10 initial responders, who relapsed during treatment (secondary failure). Of 39 patients in complete remission, increase in drug administration interval and/or drug dose reduction was attempted in 7, of which only 1 relapsed, whereas drug discontinuation was attempted in 19 patients for a median time of 8 months (range 3-68), of which 8 relapsed. Overall, in half of all disease flares, canakinumab re-introduction or intensification was successful. Canakinumab had a significant CS sparing effect permitting weaning in 21 of 41 cases. Infections (20%, severe 4%) and leucopenia (6%) led to treatment cessation in one patient.

Conclusion:

In this largest so far real-life patient cohort with refractory Still’s disease, high rates of sustained remission were induced by canakinumab both in adolescent and adult patients.

AB1201 INCREASING RATES OF INFLUENZA VACCINATION COVERAGE IN RHEUMATOID ARTHRITIS PATIENTS: DATA FROM A MULTICENTER, LONGITUDINAL COHORT STUDY OF 1,406 PATIENTS

Background:

Despite the increased incidence of influenza infection in rheumatoid arthritis (RA) patients, vaccination coverage has been shown to be suboptimal. Prospective data regarding the current rate and predictors of influenza vaccination adherence in RA patients are limited.

Objectives:

To calculate the current rate and predictors of influenza vaccination in a real-life, prospective, longitudinal RA cohort.

Methods:

Data regarding demographics, disease characteristics, treatments and co-morbidities from a multi-center, longitudinal cohort of Greek RA patients were collected at baseline and ~ 3 years later. Disease and patient characteristics were compared between patients with at least one influenza vaccine administration and non-vaccinated ones, during the 3 year follow-up period.

Results:

From a cohort of 1,569 RA patients, 1,406 with available vaccination data at baseline and 3 years later (mean interval: 2.9 years) were included; (women: 80.4%, mean age: 61.8 years, mean disease duration: 9.7 years, RF and/or anti-CCP positive: 50.4%, mean DAS-28 = 3.33, mean HAQ: 0.44, bDMARD use: 44.8%). At baseline, 54.2% of patients reported influenza vaccination in the past (31.8% during the previous season), while during the 3 year follow-up period, 81% had ≥1 influenza vaccinations (p=<0.001). Patients who received ≥1 influenza vaccine were older (63.5 vs. 54.7 years, p<0.001), were more likely to be seropositive (59.2% vs. 45.2%, p<0.001), had higher HAQ (0.46 vs. 0.36, p=0.02) and BMI (27.7 vs. 26.9, p=0.02) at baseline, more likely to be treated with bDMARDs (46.8% vs. 36.4%, p<0.001) and more likely to have chronic lung disease (9.7% vs. 5.3%, p=0.02), dyslipidemia (36.4% vs. 24.2%, p<0.001), hypertension (46.1% vs. 29.2%, p<0.001) and to report vaccination against influenza the previous season before baseline evaluation (34.9% vs. 18.2%, p<0.001). By multivariate analysis, history of influenza vaccination during the last season before baseline (OR=1.87, CI: 1.27-2.74, p=0.001), bDMARD treatment (OR=1.51, CI: 1.07-2.13, p=0.018) and age (OR=1.05, CI: 1.04-1.06, p<0.001) were independent predictors of influenza vaccination.

Conclusion:

In this ongoing, longitudinal, prospective, real-life RA cohort study, a significant increase in the influenza vaccination coverage was noted (from 53% to 81%). Influenza vaccination was independently associated with recent history of influenza vaccination, older age, and bDMARD treatment.

FRI0147 PREVALENCE OF COMORBIDITIES IN ANTIPHOSPHOLIPID SYNDROME VERSUS RHEUMATOID ARTHRITIS: A MULTICENTRE, AGE- AND SEX-MATCHED STUDY

Background:

Comorbidities in rheumatic diseases (RDs) have been associated with increased morbidity and mortality. Evidence on prevalence of comorbidities in antiphospholipid syndrome (APS) and its difference from high comorbidity burden RDs is limited.

Objectives:

To compare the prevalence of common comorbidities between APS [primary (PAPS) and Systemic lupus erythematosus (SLE)-APS] and Rheumatoid arthritis (RA) patients.

Methods:

326 APS patients from the Greek registry (237 women, mean age 48.7±13.4 years, 161 PAPS) were matched 1:2 for age and sex with 652 RA patients from Greek RA Registry. Prevalence of cardiovascular (CV) risk factors, stroke, coronary artery disease (CAD), osteoporosis, diabetes mellitus (DM), Chronic obstructive pulmonary disease (COPD), depression and neoplasms were compared between APS and RA using logistic regression analysis.

Results:

Regarding CV burden, hyperlipidemia and obesity (ΒMI≥30) were comparable while hypertension, smoking, CAD and stroke were more prevalent in APS compared to RA patients (Table 1). Osteoporosis and depression were more frequent in APS while DM, COPD and neoplasms were comparable between two groups. Comparison of APS subgroups to 1:2 matched RA patients revealed that smoking and stroke were more prevalent in PAPS and SLE-APS vs RA. Hypertension, CAD and osteoporosis were more prevalent only in SLE-APS vs. RA while DM was less prevalent in PAPS vs. RA patients.

Treatment modalities and drug survival in a systemic sclerosis real-life patient cohort

BACKGROUND

European data indicate that systemic sclerosis (SSc)-related death rates are increasing, thus raising concerns about SSc's optimal management. Herein, we describe current treatment modalities and drug survival in a real-life SSc cohort.

METHODS

Details on immunosuppressive/antiproliferative (methotrexate, mycophenolate, cyclophosphamide, azathioprine, rituximab, tocilizumab) and vasoactive agent [(endothelin receptor antagonists (ERAs), sildenafil, iloprost, and calcium channel blockers (CCB)] administration during the disease course (11.8 ± 8.4 years, mean + SD) of 497 consecutive patients examined between 2016 and 2018 were retrospectively recorded. Drug survival was assessed by Kaplan-Meier analysis.

RESULTS

Methotrexate was the most frequently administered immunosuppressive/antiproliferative agent (53% of patients), followed by cyclophosphamide (26%), mycophenolate (12%), and azathioprine (11%). Regarding vasoactive agents, CCB had been ever administered in 68%, ERAs in 38%, iloprost in 7%, and sildenafil in 7% of patients; 23% of patients with pulmonary fibrosis had never received immunosuppressive/antiproliferative agents, 33% of those with digital ulcers had never received ERAs, iloprost, or sildenafil, whereas 19% of all patients had never received either immunosuppressive/antiproliferative or other than CCB vasoactive agents. Survival rates of methotrexate, cyclophosphamide, and mycophenolate differed significantly, being 84/75%, 59/43%, and 74/63% at 12/24 months, respectively, with inefficacy being the most frequent discontinuation cause. Conversely, CCB, ERAs, and sildenafil had high and comparable retention rates of 97/91%, 88/86%, and 80/80%, respectively.

CONCLUSIONS

Existing therapeutic limitations indicate that more evidence-based treatment is warranted for successful management of SSc. Vasculopathy seems to be managed more rigorously, but the low retention rates of immunosuppressive/antiproliferative drugs suggest that effective and targeted disease-modifying agents are warranted.

The effect of TNF-a antagonists on aortic stiffness and wave reflections: a meta-analysis

Patients with rheumatoid arthritis (RA) have higher aortic stiffness and cardiovascular risk. Tumor necrosis factor alpha (TNF-a) antagonists reduce inflammation in RA and are indicated for the treatment of patients with severe active rheumatoid disease. However, it is debatable if they have favorable effects on cardiovascular health. The present meta-analysis evaluates the effect of TNF-a antagonists on aortic stiffness and wave reflections, predictors of cardiovascular events and mortality, in RA patients. A search of PubMed, Cohrane, and Embase databases was conducted to identify studies into the effect of TNF-a antagonists on aortic stiffness in RA patients. Aortic stiffness and wave reflections were assessed by aortic (carotid-femoral [cf]) pulse wave velocity (PWV) and augmentation index (AIx), respectively. cfPWV significantly improved following TNF-a antagonist treatment (mean change: -0.53 m/s, 95% CI: -0.833 to -0.218, p = 0.001), independently of age and clinical response to treatment. A more prominent reduction in cfPWV was associated with etanercept/adalimumab (mean difference: -0.62 m/s, 95% CI: -0.968 to -0.272 m/s, p < 0.001) versus infliximab (mean difference: -0.193 m/s, 95% CI: -0.847 to 0.462 m/s, p = 0.564). TNF-a antagonist treatment induced a significant improvement in AIx (mean change: -1.48%, 95% CI: -2.89 to -0.078%, p = 0.039), but this reduction was influenced by age and clinical response to treatment. The balance of evidence suggests that TNF-a antagonists may have a beneficial effect on aortic stiffness and, therefore, on cardiovascular risk. However, larger, longitudinal studies are warranted to confirm such findings.

Clinical and financial burden of active lupus in Greece: a nationwide study

Analyses of the medical and economic burden of chronic disorders such as systemic lupus erythematosus (SLE) are valuable for clinical and health policy decisions. We performed a chart-based review of 215 adult SLE patients with active autoantibody-positive disease at the predefined ratio of 30% severe (involvement of major organs requiring treatment) and 70% non-severe, followed at seven hospital centres in Greece. We reviewed 318 patients consecutively registered over three months (sub-study). Disease activity, organ damage, flares and healthcare resource utilization were recorded. Costs were assessed from the third-party payer perspective. Severe SLE patients had chronic active disease more frequently (22.4% vs 4.7%), higher average SLE disease activity index (SLEDAI) (10.5 vs 6.1) and systemic lupus international collaborating clinics (SLICC) damage index (1.1 vs 0.6) than non-severe patients. The mean annual direct medical cost was €3741 for severe vs €1225 for non-severe patients. Severe flares, active renal disease and organ damage were independent cost predictors. In the sub-study, 19% of unselected patients were classified as severe SLE, and 30% of them had chronic active disease. In conclusion, this is the first study to demonstrate the significant clinical and financial burden of Greek SLE patients with active major organ disease. Among them, 30% display chronic activity, in spite of standard care, which represents a significant unmet medical need.

The three last years of Manuel II Palaeologus' reign between two stroke attacks: aphasia or not?

The authors attempt to solve the enigma about the possible aphasia of the Byzantine Emperor Manuel II Palaeologus (1391-1425) in the 3-year period between his first and his second and fatal stroke. The texts of historians and chroniclers reveal that Manuel remained semi-paralyzed at bed and his motor disability alienated him from the state affairs and condemned him to isolation from all embassies and contact with others, except his family. Only the funeral oration of the Bishop Bessarion raises the suspicion of a speechless emperor. All testimonies referring to this infirmity are examined.

High levels of HCV core+1 antibodies in HCV patients with hepatocellular carcinoma

The core region of the hepatitis C virus (HCV) genome possesses an overlapping ORF that has been shown to encode a protein, known as the alternate reading frame protein (ARFP), F or core+1. The biological role of this protein remains elusive, as it appears to be non-essential for virus replication. However, a number of independent studies have shown that the ARFP/F/core+1 protein elicits humoral and cellular immune responses in HCV-infected individuals and interacts with important cellular proteins. To assess the significance of the core+1 humoral response in HCV-infected patients, we examined the prevalence of anti-core+1 antibodies in sera from patients with hepatocellular carcinoma (HCC) in comparison with chronically HCV-infected individuals without HCC. We produced two HCV core+1 histidine-tagged recombinant proteins for genotypes 1a (aa 11–160) and 1b (aa 11–144), as well as a non-tagged highly purified recombinant core+1/S protein (aa 85–144) of HCV-1b. Using an in-house ELISA, we tested the prevalence of core+1 antibodies in 45 patients with HCC in comparison with 47 chronically HCV-infected patients without HCC and 77 negative-control sera. More than 50 % of the serum samples from HCC patients reacted with all core+1 antigens, whereas <26 % of the sera from the non-HCC HCV-infected individuals tested positive. No core+1-specific reactivity was detected in any of the control samples. In conclusion, the high occurrence of anti-core+1 antibodies in the serum of HCC patients suggests a role for the ARFP/F/core+1 protein in the pathogenesis of HCC.

Morphometric assessments for the prognostic evaluation of human gliomas

BACKGROUND AND AIM

To correlate stereological parameters to the WHO morphological classification of brain tumours and to address the prognostic value of the different parameters.

METHODS AND MATERIALS

A quantitative analysis of 50 astrocytomas was performed by an image analysis system. At least 450 nuclei were counted and measured in every sample. The ANOVA 1-way test and Newman-Keuls modification were used for statistical evaluation.

RESULTS

The morphometric data showed significant differences between the tumour grades. We found the nuclear volume and form factor to be parameters of the degree of 'nuclear atypia' from low- to high-grade gliomas. When malignancy was increased, the mean values of nuclear orientation were found to be elevated.

CONCLUSIONS

The results of our study underline the usefulness of morphometric techniques in tumour research. These techniques seem to be an important tool for grading gliomas and also for practical therapeutic purposes.

Huntington's disease in Greece: the experience of 14 years

A large scale genetic and epidemiological study of Huntington's disease (HD) was carried out in Greece from January 1995 to December 2008. Diagnostic testing was carried out in 461 symptomatic individuals, while 256 were tested for presymptomatic purposes. The diagnosis of HD with a CAG expansion ≥ 36 was confirmed in 278 symptomatic individuals. The prevalence of HD in Greece was estimated at approximately 2.5 to 5.4:100,000, while the mean minimum incidence was estimated at 2.2 to 4.4 per million per year. The molecular diagnosis of HD was confirmed in the majority of patients (84.4%) sent for confirmation. The false-positive cases 15.6% were characterized by the absence of a family history of HD and the presence of an atypical clinical picture. The uptake of predictive testing for HD was 8.6%. A prenatal test was requested in six pregnancies. The findings of our study do not differ significantly from those of similar studies from other European countries despite the relative genetic isolation of Greece. Of interest is the identification of clusters of HD in Greece. The presence or absence of a family history of HD should be interpreted cautiously, during the diagnostic process.

An unusual presentation of neurosyphilis as a probable migraine

We describe a case which initially presented as persistent and untreatable probable migraine, which was subsequently diagnosed as neurosyphilis during the clinical evaluation. All symptoms regressed after appropriate treatment. We suggest that the possibility of neurosyphilis should be taken into account in the differential diagnosis of a persistent headache which does not respond to medication.

Long-term safety of anti-TNF treatment in patients with rheumatic diseases and chronic or resolved hepatitis B virus infection

OBJECTIVES

The aim of this prospective study was to examine the safety of anti-tumour necrosis factor (TNF) therapy in patients with rheumatic disease and hepatitis B virus (HBV) infection.

METHODS

14 patients with chronic HBV infection, 19 HBV-vaccinated patients and 19 patients with resolved HBV infection were included in the study. All HBV-infected patients received combination therapy with oral antivirals and anti-TNF agents. During treatment the levels of hepatitis B surface antibodies (anti-HBs) in HBV-vaccinated patients and of serum HBV DNA in patients with chronic or resolved HBV infection were monitored.

RESULTS

No viral reactivation was observed in patients with resolved HBV infection while anti-HBs titres decreased during anti-TNF treatment in vaccinated patients, similarly to patients treated with methotrexate alone. None of the HBV-infected patients developed liver decompensation or a significant increase in alanine aminotransferase levels. One patient (7%) treated with lamivudine and etanercept showed viral reactivation due to the emergence of a lamivudine-resistant mutant strain.

CONCLUSIONS

Anti-TNF agents represent a safe option for patients with chronic HBV infection when combined with antiviral therapy, as well as in patients previously exposed to HBV receiving no HBV prophylaxis. Resistant HBV strains may arise in patients with chronic hepatitis B, necessitating the initial use of anti-HBV agents with a low risk of resistance.

Incidence of rotational vertigo in supratentorial stroke: a prospective analysis of 112 consecutive patients

BACKGROUND

Single cases with hemispheric, cortical or subcortical, ischemic lesions presenting with rotational vertigo (RV), that challenge the notion of infratentorial or peripheral generation of RV have been published, but the incidence of this symptom in a larger series is unknown. The aim of this study was to investigate whether acute hemispheric cerebrovascular lesions cause vertiginous sensations with particular emphasis on RV.

METHODS

A total of 112 consecutive stroke patients were assessed in a prospective single-center study over a 22-month inclusion period. Rotational or other vertiginous sensations were assessed using a structured 5-item questionnaire and patients with vertigo were further evaluated with Yardley's Vertigo Symptom Scale. All subjects underwent standard clinical neuro-ophthalmological and neuro-otological testing and data were correlated to imaging findings.

RESULTS

RV was absent among our patients. Few subjects reported non-rotational vertiginous sensations with stroke onset. These were mainly right-hemispheric strokes with concomitant subcortical leukoaraiosis.

CONCLUSION

In this case series we did not find any patients with spinning sensations which is supportive of the dogma that supratenotrial lesions do not cause RV. Certain hemispheric stroke patterns, however, may be related to non-rotational dizziness.

Time-frequency analysis methods to quantify the time-varying microstructure of sleep EEG spindles: possibility for dementia biomarkers?

The time-varying microstructure of sleep EEG spindles may have clinical significance in dementia studies and can be quantified with a number of techniques. In this paper, real and simulated sleep spindles were regarded as AM/FM signals modeled by six parameters that define the instantaneous envelope (IE) and instantaneous frequency (IF) waveforms for a sleep spindle. These parameters were estimated using four different methods, namely the Hilbert transform (HT), complex demodulation (CD), matching pursuit (MP) and wavelet transform (WT). The average error in estimating these parameters was lowest for HT, higher but still less than 10% for CD and MP, and highest (greater than 10%) for WT. The signal distortion induced by the use of a given method was greatest in the case of HT and MP. These two techniques would necessitate the removal of about 0.4s from the spindle data, which is an important limitation for the case of spindles with duration less than 1s. Although the CD method may lead to a higher error than HT and MP, it requires a removal of only about 0.23s of data. An application of this sleep spindle parameterization via the CD method is proposed, in search of efficient EEG-based biomarkers in dementia. Preliminary results indicate that the proposed parameterization may be promising, since it can quantify specific differences in IE and IF characteristics between sleep spindles from dementia subjects and those from aged controls.

POLYNEUROPATHIES IN THE ELDERLY: A CLINICO PATHOLOGICAL STUDY OF 74 CASES

In elderly patients, peripheral neuropathies are common and may lead to disability. In order to investigate the relative incidence of different polyneuropathies in the elderly focusing on the contribution of nerve biopsy to their diagnosis, the authors studied 74 patients over 65 years of age with clinical, laboratory, electrophysiological, and sural nerve biopsy findings of different types of polyneuropathy. Vasculitic polyneuropathy seemed to be the most common cause of disabling neuropathy in the elderly, followed by paraneoplasia and diabetes. The possible diagnosis of idiopathic axonal neuropathy in the nine cases with neuropathy of unknown origin is discussed.

The epidemiology of primary systemic vasculitides involving small vessels in Crete (southern Greece): a comparison of older versus younger adult patients

BACKGROUND

The frequency of primary systemic small vessel vasculitides (PSV) varies among different geographic regions and age categories. We studied PSV in patients from middle-eastern Crete (Greece), and compared clinical characteristics in younger (<65 years) versus older (> or = 65 years) adult patients.

METHODS

The records of 67 patients (33 younger, 34 older adults) diagnosed with PSV during 1995-2003 who were referred to a mixed secondary/tertiary care University Hospital in Crete were reviewed. Data on clinical manifestations, diagnosis, therapy, and adverse outcomes (end stage renal disease, death) during a median follow-up of 6 (range 0-12) years were recorded. Multivariate regression analysis was applied to identify independent predictors for adverse outcomes.

RESULTS

The overall annual incidence of PSV was 19.5/million (95% confidence interval [CI] 15.7-23.4), 48.9/million (95% CI 33.8-63.9) in older and 12.4/million (95% CI 7.7-17) in younger adults. Microscopic polyangiitis was more prevalent in older patients (65%) and Wegener's Granulomatosis in younger patients (52%). Thirty-one percent of older patients developed end-stage renal disease as compared to 11% of younger patients (p=0.103). Mortality rates were 60% in older patients and 19% in younger patients (p=0.001). In multivariate regression analysis age (Beta=0.33 per 1-year, p=0.005), serum creatinine (Beta=0.29 per 1-mg/dL, p=0.011), and lung involvement (Beta=0.36, p=0.002) at the time of diagnosis were independent predictors for end stage renal disease and/or death.

CONCLUSION

This study documents increased frequency and significant mortality of PSV among older people in Crete, with MPA being the most prevalent type. Age, serum creatinine, and lung involvement are important predictors for adverse outcome in these patients.

Dietary lipids and geriatric depression scale score among elders: the EPIC-Greece cohort

In a prospective epidemiological investigation aiming to identify dietary lipids potentially associated with affective state and depression, 610 healthy men and women aged 60 years or older, participating in the EPIC-Greece cohort and residing in the Attika region had dietary, sociodemographic, anthropometric, medical and lifestyle variables ascertained at enrollment. Six to 13 years later, affective state was evaluated through the 15-point geriatric depression scale (GDS) score along with cognitive function and medical variables. In multivariate linear regression analysis, while adjusting for potential confounders, GDS score was negatively associated with dietary intake of monounsaturated lipids (MUFA) and their main source, olive oil, and positively associated with intake of polyunsaturated lipids (PUFA) and one of their principal sources, seed oils. Intake of calories, total lipids, fish and seafood or saturated lipids did not exhibit significant association with GDS. Potential non-linearities were assessed by quantile multivariate regression analysis: The median GDS score was positively associated with PUFA and seed oils intake, while other lipid groups showed no appreciable associations. The 90th percentile of the GDS score (towards the high end) exhibited significant negative associations with MUFA and olive oil, weaker positive associations with PUFA and seed oils and no appreciable association with other lipid group dietary intakes. We conclude that among Attika elders, lower intake of seed oils and higher intake of olive oil prospectively predict a healthier affective state. Olive oil intake, in particular, predicts a lower chance of scoring in the highest part of the GDS.

Circulating interleukin-10 and interleukin-12 in Parkinson's disease

BACKGROUND

Interleukin (IL)-12 is a heterodimeric cytokine produced by activated blood monocytes, macrophages and glial cells. It enhances differentiation and proliferation of T cells and increases production of proinflammatory cytokines. IL-10 is a pleiotropic cytokine produced by both lymphocytes and mononuclear phagocytes including microglia. Recent studies demonstrated the neuroprotective effect of IL-10. There is little information about the involvement of IL-12 or IL-10 in the pathophysiology of Parkinson's disease (PD).

OBJECTIVES

The objective of our study was to assess the role of IL-12 as a potential marker of immune reactions in patients with PD and to investigate whether IL-10, an immunosuppressive cytokine, may have a neuroprotective effect in the pathogenesis of PD.

PATIENTS AND METHODS

We measured using immunoassay serum IL-12 and IL-10 levels in 41 patients with PD in comparison with serum levels in 19 healthy subjects (controls) age and sex matched. IL-12 and IL-10 levels were tested for correlation with sex, age, disease duration, Hoehn and Yahr stage and the UPDRS III score.

RESULTS

The PD group presented with significantly increased IL-10 levels when compared with the control group (P = 0.02). The increase observed was not affected by the treatment status. A strong and significant correlation between IL-10 and IL-12 levels was observed in patients with PD (R(S) = 0.7, P < 0.000001).

CONCLUSIONS

Our findings suggest that IL-10 may be involved in the pathogenetic mechanisms of PD. The elevation of IL-10 and the significant correlation between IL-10 and IL-12, a proinflammatory cytokine, may suggest that immunological disturbances and neuroprotective mechanisms are involved in patients with PD.
