Epidemiological characteristics of hepatitis B and C in patients with inflammatory arthritis: Implications from treasure database

Objectives

This study aimed to evaluate the hepatitis B (HBV) and C (HCV) frequency and clinical characteristics among patients with rheumatoid arthritis (RA) or spondyloarthritis (SpA) who receive biological treatments.

Patients and methods

The observational study was conducted with patients from the TReasure database, a web-based prospective observational registry collecting data from 17 centers across Türkiye, between December 2017 and June 2021. From this database, 3,147 RA patients (2,502 males, 645 females; median age 56 years; range, 44 to 64 years) and 6,071 SpA patients (2,709 males, 3,362 females; median age 43 years; range, 36 to 52 years) were analyzed in terms of viral hepatitis, patient characteristics, and treatments used.

Results

The screening rate for HBV was 97% in RA and 94.2% in SpA patients. Hepatitis B surface antigen (HBsAg) positivity rates were 2.6% and 2%, hepatitis B surface antibody positivity rates were 32.3% and 34%, hepatitis B core antibody positivity rates were 20.3% and 12.5%, HBV DNA (deoxyribonucleic acid) positivity rates were 3.5% and 12.5%, and antibody against HCV positivity rates were 0.8% and 0.3% in RA and SpA patients, respectively. The HBsAg-positive patients were older and had more comorbidities, including hypertension, diabetes, and coronary artery disease. In addition, rheumatoid factor (RF) positivity was more common in HBsAg-positive cases. The most frequently prescribed biologic disease-modifying antirheumatic drugs were adalimumab (28.5%), etanercept (27%), tofacitinib (23.4%), and tocilizumab (21.5%) in the RA group and adalimumab (48.1%), etanercept (31.4%), infliximab (22.6%), and certolizumab (21.1%) in the SpA group. Hepatitis B reactivation was observed in one RA patient during treatment, who received rituximab and prophylaxis with tenofovir.

Conclusion

The epidemiological characteristics of patients with rheumatic diseases and viral hepatitis are essential for effective patient management. This study provided the most recent epidemiological characteristics from the prospective TReasure database, one of the comprehensive registries in rheumatology practice.

Inflammatory rheumatic diseases developed after COVID-19 vaccination: presentation of a case series and review of the literature

OBJECTIVE

An increasing number of new on-set autoimmune-inflammatory rheumatic diseases (AIRD) after COVID-19 vaccination has begun to be reported in the literature. In this article, we present our patients with new-onset AIRD after vaccination for COVID-19 and review the literature on the subject.

PATIENTS AND METHODS

We investigated the clinical characteristics and laboratory parameters of previously described "newly developed AIRD in individuals recently vaccinated for COVID-19", in 22 cases vaccinated with one of the COVID-19 vaccines (BNT162b2 or CoronaVac) approved in our country.

RESULTS

We collected 22 cases (14 female, 63.6%) that developed an AIRD after COVID-19 vaccination. Mean age was 53±14.4 (24-87) years. The interval between the last dose of vaccination and the development of the first complaint was 23.9±19.5 (4-90) days. CoronaVac was administered to four patients, and the BNT162b2 to 18 patients. AIRD-related symptoms developed in 12 patients after the first dose, in 8 patients after the second dose, and in two patients after the third dose. Twelve out of the 22 (54.5%) cases were diagnosed with rheumatoid arthritis, two with SLE, and the remaining eight patients each with leukocytoclastic vasculitis, Sjogren's syndrome, psoriatic arthritis, ankylosing spondylitis, systemic sclerosis, mixed connective tissue disease, eosinophilic granulomatosis with polyangiitis, and inflammatory myositis, respectively. Six patients had a history of documented antecedent COVID-19 infection.

CONCLUSIONS

Autoimmune/inflammatory rheumatic diseases may develop after COVID-19 vaccinations. In the era of the COVID-19 pandemic, vaccination should be questioned carefully in newly diagnosed AIRD patients.

POS1184 EPIDEMIOLOGICAL CHARACTERISTICS OF VIRAL HEPATITIS IN PATIENTS WITH RHEUMATIC DISEASES – IMPLICATIONS FROM TREASURE DATABASE

Background

Recent epidemiological data on HBV and HCV in Turkey revealed that the seroprevalence rates of hepatitis B surface antigen and antibody against HCV were 4% and 1%, respectively, and seropositivity rates for hepatitis B surface antibody and hepatitis B core antibody were 31.9% and 30.6%, respectively. A previous multicenter nationwide study conducted in Turkey reported that the HBsAg positivity was determined in 2.3% of patients with rheumatoid arthritis (RA) and 3% of patients with ankylosing spondylitis (AS), and the anti-HCV positivity was detected in 1.1% of patients in each group. Given these rates, viral hepatitis is still considered a potential threat to patients with rheumatic diseases, specifically for the treatment-related viral reactivation.

Objectives

This study aimed to evaluate the serologic HBV and HCV frequency and clinical characteristics among our patients with RA or SpA and receive biological treatments based on this background.

Methods

The prospective TReasure database, which observationally collects data of patients with rheumatic diseases from fifteen centers across Turkey, was analyzed for viral hepatitis, patient characteristics, and treatments used. TReasure registry study protocol, and the data collection was started on December 2017. At the time of the analysis for this study was performed, the registry database included 3147 patients with RA and 6071 patients with SpA. For hepatitis B; Hepatitis B surface antigen (HBsAg), anti-HBV core antibody (anti-HBc) and anti-HBV surface antibody (Anti-HBs) tests were evaluated. HBV-DNA was studied in HBsAg positive patients. Anti-HCV antibody has been studied for HCV. The clinical and serological HBV reactivation in the follow-up of the patients was evaluated by looking at the HBV-DNA viral loads.

Results

A total of 9218 patients (3147 RA and 6071 patients with SpA) were included in the analyses. The screening rate for HBV was 97% in RA and 94.2% in SpA groups. HBsAg positivity rates were 2.6% and 2%, anti-HBs positivity rates were 32.3% and 34%, anti-HBc positivity rates were 20.3% and 12.5%, HBV DNA positivity rates were 3.5% and 12.5%, and anti-HCV positivity rates were 0.8% and 0.3% in these groups, respectively (Table 1).

Conclusion

The epidemiological characteristics of patients with rheumatic diseases and viral hepatitis are essential for effective patient management. This study provided the most recent epidemiological characteristics from the prospective TReasure database, one of the most comprehensive registries in rheumatology practice. According to the results of our study; It can be thought that there is no risk in the choice of treatment by the rheumatologist in patients who receive appropriate prophylaxis.

Interleukin-1 Inhibitors and Vaccination Including COVID-19 in Inflammatory Rheumatic Diseases: A Nonsystematic Review

Newly emerging variants of coronavirus 2 (SARS-CoV-2) raise concerns about the spread of the disease, and with the rising case numbers, the Coronavirus disease 2019 (COVID-19) remains a challenging medical emergency towards the end of the year 2021. Swiftly developed novel vaccines aid in the prevention of the spread, and it seems that a specific cure will not be at hand soon. The prognosis of COVID-19 in patients with autoimmune/autoinflammatory rheumatic diseases (AIIRD) is more severe when compared to the otherwise healthy population, and vaccination is essential. Evidence for both the efficacy and safety of COVID-19 vaccination in AIIRD under immunosuppression is accumulating, but the effect of Interleukin-1 on vaccination in general and in AIIRD patients is rarely addressed in the current literature. In light of the current literature, it seems that the level of agreement on the timing of COVID-19 vaccination is moderate in patients using IL-1 blockers, and expert opinions may vary. Generally, it may be recommended that patients under IL-1 blockade can be vaccinated without interrupting the anti-cytokine therapy, especially in patients with ongoing high disease activity to avoid disease relapses. However, in selected cases, after balancing for disease activity and risk of relapses, vaccination may be given seven days after the drug levels have returned to baseline, especially for IL-1 blocking agents with long half-lives such as canakinumab and rilonacept. This may help to ensure an ideal vaccine response in the face of the possibility that AIIRD patients may develop a more pronounced and severe COVID-19 disease course.

Clinical and laboratory factors associated with the bamboo spine in patients with axial spondyloarthritis: are there clues for the bamboo spine?

OBJECTIVES

To analyse the clinical and laboratory factors associated with bamboo spine.

METHODS

Data of patients fulfilling the 2009 ASAS classification criteria for axial spondyloarthritis, registered in the national, multicentre, longitudinal, and observational database of TReasure was analysed. Radiographs were assessed using the Bath Ankylosing Spondylitis Radiologic Index (BASRI). Data of patients with a bamboo spine (Group 1) was compared to data derived from patients with a longstanding disease of at least 15 years but no syndesmophytes (Group 2).

RESULTS

Out of the 5060 patients, 1246 had eligible radiographs. There were 111 patients (8.9%) with a bamboo spine. Male sex was more common among patients with bamboo spine. The median BMI of 27.7 (25.8-31.1) in Group1 was higher than the BMI of 25.9 (22.9-29.2) in Group 2 (p<0.001). Hip arthritis, present or documented by a physician, was more common in Group 1 [(58/108 (53.7%) vs. 35/103 (34%), p=0.004]. There was a tendency towards a more prevalent enthesitis in these patients [29.1% (25/86) vs. 15.9%(11/69), p=0.054]. HLA-B27 status did not differ between groups. Smoking was more prevalent in Group 1. Multivariate logistic regression analysis revealed that male sex, body mass index, hip arthritis, and enthesitis are associated with bamboo spine in axSpA.

CONCLUSIONS

Bamboo spine was more common in the male sex and associated with a delay in diagnosis, high BMI, hip involvement, and enthesitis. The constellation of increased body weight, hip arthritis, and enthesitis may imply that mechanical stress contributes to radiographic damage in the presence of chronic inflammation.

Pathogenesis and treatment of cytokine storm in COVID-19

COVID-19 is a viral infection caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that killed a large number of patients around the world. A hyperinflammatory state resulting in a cytokine storm and adult respiratory distress syndrome seems to be the major cause of the death. Many mechanisms have been suggested in the pathogenesis of COVID-19 associated cytokine storm (COVID-CS). Insufficient viral clearance and persistence of a strong cytokine response despite inadequate antiviral immunity seem to be the main mechanisms underlying the pathogenesis. The diagnosis of COVID-19 is based on relatively constant clinical symptoms, clinical findings, laboratory tests, and imaging techniques, while the diagnosis of COVID-CS is a rather dynamic process, based on evolving or newly emerging findings during the clinical course. Management of COVID-19 consists of using antiviral agents to inhibit SARS-CoV-2 replication and treating potential complications including the cytokine storm together with general supportive measures. COVID-CS may be treated using appropriate immunosuppressive and immunomodulatory drugs that reduce the level of inappropriate systemic inflammation, which has the potential to cause organ damage. Currently corticosteroids, IL-6 blockers, or IL-1 blockers are most widely used for treating COVID-CS.

Uveitis-related Factors in Patients With Spondyloarthritis: TReasure Real-Life Results

PURPOSE

Spondyloarthritis (SpA) is a group of diseases with overlapping skeletal and extra-articular features. Acute anterior uveitis (AAU) is the most common extra-articular manifestation of SpA. The relation between AAU and SpA is well defined in the current literature. Our study aims to analyze the frequency and factors associated with AAU in different forms of SpA in a large nationwide cohort of Turkish SpA patients.

DESIGN

Retrospective cohort study.

METHODS

The data were obtained from the TReasure database, which compiles data from records of the web-based Rheumatoid Arthritis (RA) and SpA patients treated with biological disease-modifying anti-rheumatismal drugs from different regions of Turkey. The clinical characteristics of SpA and uveitis are recorded.

RESULTS

Data of the 4,297 SpA patients were included in the study. Overall, 475 of 4,297 patients (11.0%) had experienced 1 or more episodes of uveitis. SpA patients with older age (P < .001), a smoking history (P = .004), delayed diagnosis (P = .001), longer disease duration (P < .001), arthritis (P < .001), positive HLA-B27 (P < .001), a family history of SpA (P < .001), and radiographic damage (presence of sacroiliitis, syndesmophytes, bamboo spine, hip involvement) (P < .001 for all) more commonly had uveitis. On the other hand, uveitis was less prevalent in patients with psoriasis and psoriatic arthritis (P < .001 for both).

CONCLUSION

Uveitis may be the key feature leading to SpA diagnosis. Patients with radiographic damage and long disease duration have an increased risk for uveitis in both male and female SpA patients. Patients with uveitis should be referred to a rheumatologist for a thorough evaluation of SpA.

POS0935 DO PERIPHERAL AND EXTRA MUSCULOSKELETAL MANIFESTATIONS HAVE AN IMPACT ON BIOLOGIC DMARD PRESCRIBING PATTERNS IN AXIAL SPONDYLOARTHRITIS: THE RESULTS OF TREASURE EXPERIENCE

Background:

Axial spondyloarthritis (axSpA) is a chronic inflammatory rheumatic disease mainly affecting sacroiliac joints and spine. Peripheral arthritis, dactylitis and enthesitis may also occur. Extra musculoskeletal manifestations (EMMs; uveitis [AAU], inflammatory bowel disease [IBD] and psoriasis [Pso] are among the most common ones) are important features and might have an impact on the disease burden in patients with axSpA. The presence of EMM, in particular IBD and AAU could influence the choice of TNFi however little is known regarding the role of peripheral manifestations together with the EMM on the prescribing patterns in axSpA patients.

Objectives:

To examine the frequency of peripheral and EMMs in a real-world axSpA cohort and their effect on the choice of first advanced treatment.

Methods:

In total 1687 axSpA patients (58% male and the mean age (±SD) was 38.5 ± 10.9) who initiated his/her first biologic were included in the present analysis. The data for the current study was obtained from the TReasure web-based registry; in which RA and SpA patients treated with bDMARDs from different regions of Turkey. Baseline demographic, disease related characteristics, peripheral and EMMs were extracted. Characteristics of patients with and without peripheral/extra-musculoskelatal involvement were compared as well as factors/covariates associated with the choice of first TNFi and secukinumab was analysed.

Results:

Enthesis (28.2%) was found the most common peripheral manifestations and peripheral arthritis (26.4%) and hip arthritis (24.4%) followed it. Symptom duration to the first advanced treatment initiation was significantly shorter in axSpA patients with peripheral arthritis, enthesitis, dactylitis and psoriasis and longer in hip arthritis and AAU. HLA-B27 positivity was significantly lower in patients with arthritis, psoriasis and IBD and higher with hip arthritis and AAU. In multivariate analysis the presence of IBD is significantly associated with the preference of monoclonal TNFi (mab) over etanercept (ETA) (OR 5,770; 95%CI 1.788-18.616). However ETA was preferred in patients with hip arthritis (p=0.003), longer symptom duration (p=0.049), and using sulfasalazine (p=0.043). In comparison with mabs, secukinumab (SEC) prescription was found to be significantly associated with higher age (p=0.001), sulfasalazin (p=0.001) and methotrexate usage (p=0.053) among axSpA patients need their first advanced treatment.

Conclusion:

The results of the current study confirm the pathophsyologic associations of peripheral involvement and EMM in axSpA patients. Apart from hip arthritis the presence of IBD has an impact on the prescription of advanced treatment in real-life.

AB0479 LONGTERM RETENTION RATE OF CERTOLIZUMAB PEGOL IN AXIAL SPONDYLOARTHRITIS IS HIGHER: DATA FROM TURKBIO

Background:

Choosing the best treatment strategy for a patient is one of the most difficult issues in modern rheumatology, as there are various factors affecting drug therapy in chronic diseases, such as efficacy, safety, and compliance. Physicians take care of long-term retention rate and responses for discontinuation of candidate drug.

Objectives:

The purpose of this study to assess the drug survival of certolizumab pegol (CZP) in patients with axial spondyloarthritis (ax-SpA) and to identify the predictors and reasons for discontinuation.

Methods:

Data on patient characteristics, demographics, diagnosis, duration of disease, treatment and outcomes have been collected since 2011 in Turkish Biologic (TURKBIO) Registry. By the end of December 2020, 410 ax-SpA patients received CZP and were included. Kaplan Meier plot was used for drug survival analysis. Cox regression analysis was performed to evaluate the predictor associated with drug survival.

Results:

During the median 54 months follow-up, 92 (22.4%) patients discontinued the CZP treatment. The reasons for discontinuation: ineffectivity was 58.7% (n=54), adverse events was 6.5%, pregnancy was 3.3% and surgery was 4.3%. The baseline characteristics of patients continue with CZP and discontinuation due to ineffectiveness were shown in the Table 1. Patients who discontinued CZP had higher HAQ, BASFI and BASDAI values. Moreover, they were more co-treated with NSAIDs and csDMARDs. At the month 36, retention rate of CZP was 71.5% in patients with ax-SpA (Figure 1).

Conclusion:

Real life experience from this nationwide TURKBIO registry show higher long-term retention rate of CZP in ax-SpA. Higher baseline disease activity and functional limitation predict discontinuation of CZP. Adding NSAIDs and csDMARDs to the treatment of the patient with poor prognosis cannot increase retention rates.

Hemophagocytic lymphohistiocytosis: a review inspired by the COVID-19 pandemic

Hemophagocytic syndrome (HPS) or hemophagocytic lymphohistiocytosis (HLH) is an acute and rapidly progressive systemic inflammatory disorder characterized by cytopenia, excessive cytokine production, and hyperferritinemia. Common clinical manifestations of HLH are acute unremitting fever, lymphadenopathy, hepatosplenomegaly, and multiorgan failure. Due to a massive cytokine release, this clinical condition is considered as a cytokine storm syndrome. HPS has primary and acquired (secondary, reactive) forms. Its primary form is mostly seen in childhood and caused by various mutations with genetic inheritance and, therefore, is called familial HLH. Secondary HLH may be caused in the presence of an underlying disorder, that is, secondary to a malignant, infectious, or autoimmune/autoinflammatory stimulus. This paper aims to review the pathogenesis and the clinical picture of HLH, and its severe complication, the cytokine storm, with a special emphasis on the developed classification criteria sets for rheumatologists, since COVID-19 infection has clinical symptoms resembling those of the common rheumatologic conditions and possibly triggers HLH. MED-LINE/Pubmed was searched from inception to April 2020, and the following terms were used for data searching: “hemophagocytic syndrome” OR “macrophage activation syndrome” OR “hemophagocytic lymphohistiocytosis”, OR “cytokine storm”. Finally, AND “COVID-19” was included in this algorithm. The selection is restricted to the past 5 years and limited numbers of earlier key references were manually selected. Only full-text manuscripts, published in an English language peer-reviewed journal were included. Manuscript selection procedure and numbers are given in Fig. 2. Briefly, the database search with the following terms of “Hemophagocytic syndrome” OR “Macrophage activation syndrome” OR “Hemophagocytic lymphohistiocytosis” OR “Cytokine storm” yielded 6744 results from inception to April 2020. The selection is restricted to the past 5 years and only limited numbers of earlier key references were selected, and this algorithm resulted in 3080 manuscripts. The addition of (AND “COVID-19”) resulted in 115 publications of which 47 studies, together with four sections of an online book were used in the final review. No statistical method was used. HLH is triggered by genetic conditions, infections, malignancies, autoimmune-autoinflammatory diseases, and some drugs. In COVID-19 patients, secondary HLH and cytokine storm may be responsible for unexplained progressive fever, cytopenia, ARDS, neurological and renal impairment. Differentiation between the primary and secondary forms of HLH is utterly important, since primary form of HLH requires complicated treatments such as hematopoietic stem cell transplantation. Further studies addressing the performance of HScore and other recommendations in the classification of these patients is necessary.

THU0290 THE EARLIER IMMUNOSUPPRESIVE TREATMENT MAY PREVENT MAJOR ORGAN INVOLVEMENT IN BEHCET DISEASE

Background:

Immunosuppressive(IS) agents are used for the treatment and prevention of major organ involvement in Behçet’s disease.

Objectives:

We aimed to investigate the rate of new major organ involvement development in patients under IS treatment for any reason during follow-up,and to compare the rate with patients never receiving IS treatments.

Methods:

Data were collected retrospectively from files of patients who had a minimum follow-up duration of 6 months and were diagnosed with Behçet’s disease according to the ISG criteria.Major organ manifestations were defined as ocular, vascular, neurologic, and gastrointestinal involvement.ISs were defined as azathioprine,cyclophosphamide, corticosteroids,interferon alfa,TNF inhibitors and cyclosporine.

Results:

640 patients were included in the study,of which 354 (55%) were male.The median age at diagnosis was 28(IQR: 23-35); the median follow-up duration was 5.75 (IQR: 3-8.91) years.Erythema nodosum was more common in females, but uveitis and vascular involvement were more prevalent among male patients (Table 1).198 (31%) patients had uveitis, 163 (26%) patients had vascular involvement, 63 (10%) patients had neurological involvement and 11(2%) patients had gastrointestinal involvement.The distribution of these 241 vascular events is displayed in Figure 1. 324 (51%) patients were not receiving any immunosuppressives when they developed their first major organ involvement.On the other hand, a total number of 348 (53%) patients were started on immunosuppressives [324 (51%) for major organ involvement, 24 (3%) for mucocutaneous involvement].38 (11%) of these patients developed a different major organ involvement (Table 2) under ISs. 23 of these 38 patients were on Azathioprine; eight were on Cyclophosphamide and Azathioprine, three were on interferon-alfa.Among patients receiving IS for any reason, 91 (28%) experienced relapses in the same organ.

Conclusion:

During follow-up in our tertiary rheumatology center, about 40 % of patients receiving immunosuppressives, either experienced a new and different organ manifestation or had a relapse in the same organ.Our results suggest that earlier and more aggressive treatment may be necessary for the treatment of patients with BD to prevent both relapses and new major organ involvement in daily practice.

Prevalence of inflammatory back pain and radiologic sacroiliitis is increased in patients with primary Sjögren's syndrome

Introduction

The prevalence of Sjögren's syndrome (SS) in patients with the diagnosis of SpA has been reported to be higher than normal population. Yet, the vice-versa is unclear. In this study, we aimed to investigate the prevalence of IBP, radiologic sacroiliitis and SpA in patients with primary SS.

Methods

85 patients followed at the rheumatology clinics of the Marmara and Kocaeli Universities with the diagnosis of primary SS between November 2011 and August 2012 were included in this study. The control group consisted of 100 age-and gender-matched patients. Inflammatory back pain and axial SpA were diagnosed according to the assessment of spondylo arthritis International Society (ASAS) criteria.

Results

83 patients were (97%) female and 2 (3%) were male. Mean age of the patients was 49.1 (±11) years. Mean disease duration was 7.3 (±4) years. The patient and control groups were comparable in terms of age and gender (p > 0.05). Inflammatory back pain was observed in 21 (24.7%) of 85 primary SS patients and in 4 (4%) of 100 control subjects (p < 0.001), radiographic sacroiliitis was demonstrated in 9 (10.5%) of primary SS patients and 2 (2%) of the control subjects (p = 0.025). Remaining SpA findings were not encountered in either group.

Conclusion

inflammatory back pain and radiologic sacroiliitis is increased in patients with primary SS. Whether IBP, SI joint inflammation and radiologic sacroiliitis is due to the co-existence of SpA and primary SS or IBP is an underdiagnosed clinical feature of SS deserves further studies of large patient numbers.

Oral ulcer activity in Behcet's disease: Poor medication adherence is an underestimated risk factor

OBJECTIVE

The aim of this study was to evaluate the relationship between oral ulcer activity and medication adherence according to gender in Behçet's disease (BD) patients.

MATERIAL AND METHODS

The study group included 330 BD patients (F/M: 167/163, mean age: 38.5±10.5 years). Oral ulcer activity and medication adherence were evaluated in the previous month. Medication adherence was evaluated using the 8-item Morisky Medication Adherence Scale (MMAS-8) having a score range of "0" to "8" with high scores indicating better adherence. Low adherence was defined as <6 points on MMAS-8.

RESULTS

Over half of the group had active oral ulcers (n=219, 66.4%) within the month preceding the visit. The number of oral ulcers was significantly higher in female patients with low medication adherence (2.39±3.24) than in the rest of the female group (1.28±2.05; p=0.023). Although a similar trend was also observed in male patients (2.14±3.3 vs. 1.81±2.31), a significant relationship was not observed (p=0.89). The frequency of medication intake per day was lower in patients with high medication adherence than in the rest of the study group (p=0.04).

CONCLUSION

Low medication adherence is a hidden risk factor in the management of BD. Poor adherence was associated with oral ulcer activity in female BD patients.

The validity and reliability of Systemic Lupus Erythematosus Quality of Life Questionnaire (L-QoL) in a Turkish population

Background

Systemic lupus erythematosus (SLE) may have a profound impact on quality of life. There is increasing interest in measuring quality of life in lupus patients. The purpose of this study was to investigate the validity and reliability of SLE Quality of Life Questionnaire (L-QoL) in Turkish SLE patients.

Methods

SLE according to 2012 Systemic Lupus International Collaborating Clinics Classification Criteria were recruited into the study. Demographic data, clinical parameters and disease activity measured with the Systemic Lupus Erythematosus Disease Activity Index-2000 (SLEDAI-2K); were noted. Nottingham Health Profile and Health Assessment Questionnaire were filled out in addition to the Turkish L-QoL (LQoL-TR). Internal consistency, test–retest reliability, and convergent and discriminant validity were evaluated.

Results

The mean age of participants was 43.55 ± 14.33 years and the mean disease duration was 89.8 ± 92.1 months. The patients filled out LQoL-TR in 2.5 min. Strong correlation of LQoL-TR with all subgroups of the Nottingham Health Profile and the Health Assessment Questionnaire were established showing the convergent validity. The highest correlation was demonstrated with emotional reactions (rho = 0.72) and sleep component (rho = 0.65) of the Nottingham Health Profile scale ( p < 0.0001). Its poor and not significant correlation with nonfunctional parameters (age, disease duration, perceived general health, SLEDAI-2K) showed its discriminative properties. LQoL-TR demonstrated good internal reliability with a Cronbach’s α of 0.93 and test–retest reliability with intraclass correlation coefficient of 0.87.

Conclusion

The LQoL-TR is a practical and useful tool which demonstrates good validity and reliability.

Immune and inflammatory gene expressions are different in Behçet's disease compared to those in Familial Mediterranean Fever

OBJECTIVE

The immune classification of Behçet's disease (BD) is still controversial. In this study, we aimed to compare the immune/inflammatory gene expressions in BD with those in familial Mediterranean fever (FMF), an autoinflammatory disorder with innate immune activation.

MATERIAL AND METHODS

CD4+ T cells and CD14+ monocytes were isolated from the peripheral blood mononuclear cells of Behçet's disease patients (n=10), FMF (n=6) patients, and healthy controls (n=4) with microbeads, and then, the mRNA was isolated. The expressions of 440 genes associated with immune and inflammatory responses were studied with a focused DNA microarray using a chemiluminescent tagging system. Changes above 1.5-fold and below 0.8-fold were accepted to be significant.

RESULTS

In BD patients, in the CD4+ T-lymphocyte subset, interleukin 18 receptor accessory protein (1.7-fold), IL-7 receptor (1.9-fold), and prokineticin 2 (2.5-fold) were all increased compared to those in FMF patients, whereas chemokine (C-X3-C motif ) receptor-1 (CX3CR1) (0.7-fold) and endothelial cell growth factor-1 (0.6-fold) were decreased. In the CD14+ monocyte population, the V-fos FBJ murine osteosarcoma viral oncogene homolog (1.5-fold), Interleukin-8 (IL-8) (2.1-fold), and Tumor Necrosis Factor alpha (TNF-α) (1.8-fold) were all increased, whereas the chemokine (C-C motif ) ligand 5 (CCL5) (0.6-fold), C-C chemokine receptor type 7 (0.6-fold), and CX3CR1 (0.7-fold) were decreased, again when compared to those in FMF. Compared to healthy controls in the CD4+ T-lymphocyte population, in both BD and FMF patients, pro-platelet basic protein and CD27 had elevated expression. In BD and FMF patients, 24 and 19 genes, respectively, were downregulated, with 15 overlapping genes between both disorders. In the CD14+ monocytes population, chemokine (C-C motif ) receptor-1 (CCR1) was upregulated both in BD and FMF patients compared to that in the controls, whereas CCL5 was downregulated.

CONCLUSION

Immune and inflammatory gene expressions seem to be variable in both the innate (CD14+) and adaptive (CD4+) immune responses in BD and FMF patients compared to those in controls, suggesting differences in immune regulation between the two disorders.

Sonographic measurement of Achilles tendon thickness in seronegative spondyloarthropathies

OBJECTIVE

To define the best cut-off value for identifying Achilles tendon thickening using ultrasound (US) in patients with spondyloarthropathies (SpA) and to assess its diagnostic utility in comparison with different cut-off values used in the literature.

MATERIAL AND METHODS

One-hundred and one subjects (55 SpA patients and 46 age and body mass index ((BMI)-matched healthy controls (HC)) were investigated. US was performed using a MyLab70 US system (Esaote Biomedica, Genoa, Italy) with a linear probe (6-18 MHz). Three images per Achilles enthesis were stored and the antero-posterior thickness of the enthesis was measured at the level of the Achilles tendon deeper margin insertion into the calcaneal bone on the longitudinal median scan. The best cut-off value for each gender was determined by ROC curve analysis and compared to the other cut-off values in the literature: 1) 5.29 mm for both genders, and 2) 5.5 mm for females and 6.2 mm for males. The number of measurements exceeding the cut-off values as well as sensitivity (SE), specificity (SP), positive (PPV) and negative (NPV) predictive values were calculated.

RESULTS

A significant difference was observed for Achilles enthesis thickness between genders (mean±SD: 4.6±0.7 mm in males vs. 4.0±0.8 mm in females, p<0.00) and between SpA patients and HC (mean±SD: 4.4±0.8 mm in SpA patients vs. 4.0±0.8 mm in HC, p<0.001). The ROC curve analysis revealed the best cut-off value to be 3.7 mm for females and 4.8 mm for males (SE: 43-70%, SP: 59-85%, PPV: 66-79%, NPV: 54-63%). Previously reported cut-off values were found to have high SP (91-98%) but very low SE (2-11%).

CONCLUSION

Achilles tendon thickness differs between genders; thus, it is crucial to refer to normal values that are specific for gender. High cut-off values, as previously suggested, showed very low SE in the current study. When Achilles enthesis thickening is used for the purpose of screening enthesitis in SpA patients, a lower cut-off value has a higher SE with slightly worse SP, PPV and NPVs.

Accelerated infusion rates of rituximab are well tolerated and safe in rheumatology practice: a single-centre experience

Due to the possible risk of infusion reactions of rituximab (RTX), a slow infusion rate (total infusion time, 255 min) is suggested for rheumatological use. However, especially in oncology field, accelerated infusion of RTX is reported to be well tolerated and safe. The aim of our study was to evaluate whether accelerated infusion rates of RTX would similarly be safe and tolerable in rheumatoid arthritis (RA) patients and other off-label rheumatological indications. All patients treated with RTX for RA and other autoimmune diseases between May 2011 and January 2012 were recruited to the study. Each treatment course consisted of two RTX 1,000 mg infusions, 2 weeks apart. Total time of the infusion for the first cycle was 255 min. Second and subsequent infusions were administered over 120 min as follows: 0-30 min, 100 mg; 30-60 min, 200 mg; 60-90 min, 300 mg; and 90-120 min, 400 mg. The Clinical Trials Classification of Adverse Events (CTCAE) version 4.3 was used to categorise side effects. The study population comprised 68 patients [F/M, 59:9; mean age, 52.4 (10.6) years]: 60 with RA, 4 with systemic lupus erythematosus (SLE), 1 with non-Hodgkin's lymphoma with SLE and 3 with vasculitis. A total of 77 fast infusions were administered. Eleven patients (16.2 %) had taken a fast infusion at the first course. A total of nine patients experienced at least one AE. Seven patients had a reaction on the first infusion (infusion-related reaction (IRR)), two patients on the second infusion and one patient on both infusions. When graded from 1 to 5 according to CTCAE v. 4.3, grade 1 IRRs were observed in a total of seven patients and grade 2 IRR in three patients. In this study of fast infusions, adverse events after RTX were mostly mild and seem to be well tolerated. Faster rituximab infusion times seem to be safe and might be incorporated into routine practice.

A case of Budd–Chiari syndrome with Behcet’s disease and oral contraceptive usage

We present a case of Budd-Chiari syndrome (BCS) having two risk factors, Behcet's disease (BD) and oral contraceptive (OC) usage. A 33-year-old woman with BD was admitted to the Emergency Unit with nausea, vomiting, abdominal pain, abdominal distention, and confusion started 12 days ago before admission. Since the patient was in a shock state, she was taken to the Intensive Care Unit (ICU) with the suspicion of abdomen-originated sepsis. Abdominal ultrasound showed massive hepatosplenomegaly and moderate ascites. Abdominal MRI revealed an inferior vena cava (IVC) obstruction starting above the renal veins and diffuse thrombosis of the right and medial hepatic veins. An extensive thrombosis of the IVC and the hepatic veins (BCS) which led to shock was diagnosed. In addition to BD, the unnotified OC usage for a year by the patient without her doctor's knowledge was recognized as possible precipitating factor of BCS. Pulse methylprenisolone was started for three consecutive days to treat active BD-induced vasculitis. IVC digital subtraction angiography (DSA) showed occlusion of the IVC below the hepatic veins with extensive collateral circulation originating at the occlusion level suggesting that obliteration had a subacute or chronic course. Since intralesional thrombolytic therapy failed, the patient was transferred to a liver transplantation center. While waiting for an appropriate donor, the patient died due to hepatic failure. Since BCS is mortal and deemed multi-factorial, every patient with a thrombotic risk factor such as BD should be questioned for other possible causes of thrombosis.

The investigation of sacroiliitis with different imaging techniques in spondyloarthropathies

PURPOSE

The aim of this study was to compare the value of different imaging techniques in spondyloarthropathy (SpA) patients with inflammatory low back pain.

PATIENTS AND METHODS

We evaluated 54 patients who fulfilled the European spondyloarthropathy classification criteria and had inflammatory low back pain. They were subdivided into two groups according to changes on plain radiography rated on a 0-4 scale according to modified New York criteria. Group A patients had at least grade-2 unilateral or bilateral changes in the sacroiliac (SI) joints, whereas group B included patients with radiologic changes not exceeding grade 0-1. Quantitative SI scintigraphy and magnetic resonance imaging (MRI) were performed to investigate the value of these techniques to the diagnosis of sacroiliitis, and the sacroiliac joint:sacrum uptake ratios were calculated. Scintiscanning was done in 80 healthy subjects to define the normal range.

RESULTS

The sensitivities of plain radiography, quantitative SI scintigraphy, and MRI were 61%, 55%, and 89%, respectively, among the patients with SpA. MRI and quantitative SI scintigraphy detected sacroiliitis in 97% and 49% of group A, respectively. In group B, these results were 76% and 66%, respectively.

CONCLUSION

Magnetic resonance imaging is the most sensitive method for detecting acute or chronic changes in SpA patients with histories of inflammatory low back pain and normal or indeterminate findings on plain radiographs.

Effects of simvastatin only or in combination with continuous combined hormone replacement therapy on serum lipid levels in hypercholesterolaemic post-menopausal women

AIMS

To evaluate the effects of simvastatin only or combined with continuous hormone replacement therapy on the serum lipid profile in hypercholesterolaemic post-menopausal women.

METHODS AND RESULTS

One hundred hypercholesterolaemic post-menopausal women were given either simvastatin 10 mg daily together with oestrogen 0.625 mg and medroxyprogesterone 2.5 mg daily (HRT+simvastatin group) (n:50) or simvastatin 10 mg daily (simvastatin only group) (n:50) in a prospective manner. Serum total, low density lipoprotein, and high density lipoprotein cholesterol and triglyceride levels were measured at baseline, at 3 and 6 months. The initial mean (+/-SD) cholesterol values were as follows for the HRT+simvastatin group and the simvastatin only group, respectively: total cholesterol 240. 0+/-28.0 and 248.9+/-28.2 mg x dl(-1); low density lipoprotein cholesterol 174.7+/-25.6 and 175.1+/-25.9 mg x dl(-1); high density lipoprotein cholesterol 37.2+/-5.0 and 39.9+/-7.3 mg x dl(-1). Compared with the baseline, total and low density lipoprotein cholesterol levels decreased; and high density lipoprotein cholesterol levels increased significantly at 3 and 6 months in both groups. However, the mean percent reduction in total cholesterol and low density lipoprotein cholesterol was significantly greater in the HRT+ simvastatin group compared with the simvastatin only group both at 3 months (12.3+/-7.0% vs 8.9+/-6.2%;P<0.01; and 19.0+/-10.6% vs 13.2+/-10.4%;P< 0.005, respectively) and at 6 months (14.6+/-7.7% vs 11.3+/-7.4%;P<0.05 and 23.3+/-9.7% vs 15.8+/-12.3%;P<0.005, respectively). The mean percent increase in serum high density lipoprotein cholesterol concentrations was also significantly greater in the HRT+simvastatin group compared with the simvastatin only group at both times (14.6+/-11.8% vs 9.8+/-11.8%;P<0.005, at 3 months, and 21.3+/-15.2% vs 11.1+/-12.5;P<0.005, at 6 months, respectively). Furthermore, significantly more patients in the HRT+simvastatin group than in the simvastatin only group attained their target treatment goals dictated by the National Cholesterol Education Program Adult Treatment Panel II Guidelines. Although the mean percent decrease in triglyceride levels was significantly greater in the HRT+simvastatin group at 3 months, the significance disappeared at 6 months.

CONCLUSION

The combination of simvastatin and continuous combined hormone replacement therapy seems to be more effective than simvastatin only in the treatment of hypercholesterolaemia in post-menopausal women.

Elevated hepatic lipase activity and low levels of high density lipoprotein in a normotriglyceridemic, nonobese Turkish population

Low levels of high density lipoprotein cholesterol (HDL-C) are associated with increased risk of coronary heart disease and, in the United States, are often associated with hypertriglyceridemia and obesity. In Turkey, low HDL-C levels are highly prevalent, 53% of men and 26% of women having HDL-C levels <35 mg/dl, in the absence of hypertriglyceridemia and obesity. In this study to investigate the cause of low HDL-C levels in Turks, various factors affecting HDL metabolism were assessed in normotriglyceridemic Turkish men and women living in Istanbul and in non-Turkish men and women living in San Francisco. Turkish men and women had significantly lower HDL-C levels than the San Francisco men and women, as well as markedly lower apolipoprotein A-I levels (25 and 39 mg/dl lower, respectively). In both Turkish and non-Turkish subjects, the mean body mass index was <27 kg/m2, the mean triglyceride level was <120 mg/dl, and the mean total cholesterol was 170-180 mg/dl. The mean hepatic triglyceride lipase activity was 21% and 31% higher in Turkish men and women, respectively, than in non-Turkish men and women, and remained higher even after subjects with a body mass index >50th percentile for men and women in the United States were excluded from the analysis. As no dietary or behavioral factors have been identified in the Turkish population that account for increased hepatic triglyceride lipase activity, the elevation most likely has a genetic basis. high density lipoprotein in a normotriglyceridemic, nonobese Turkish population.
