Objective. Age at onset has been shown to affect the clinical course and outcome of systemic lupus erythematosus (SLE). Herein, we aimed to define the differences in clinical characteristics, organ damage, and survival between patients with juvenile-onset (jSLE) and adult-onset SLE (aSLE). Methods. For the study, 719 patients (76.9%) with aSLE and 216 (23.1%) with jSLE were examined. Comparisons between the groups were made for demographic characteristics, clinical features, auto-antibody profiles, damage, and survival rates. Results. These results were significantly more frequent in jSLE: photosensitivity, malar rash, oral ulcers, renal involvement, neuropsychiatric (NP) manifestations, and autoimmune hemolytic anemia (AIHA). Of the autoantibodies, a higher frequency of anti-dsDNA and anticardiolipin IgG and IgM were observed in the jSLE group. A significant proportion of patients with aSLE had anti-Sm positivity and pleuritis. The proportion of patients with jSLE who developed organ damage was comparable to that of patients with aSLE (53% vs 47%) and the mean damage scores were similar in both groups. Renal damage was significantly more frequent in jSLE while musculoskeletal and cardiovascular system damage and diabetes mellitus were more prominent in aSLE. Comparison of survival rates of the 2 groups did not reveal any significant differences. Conclusion. We report a higher frequency in the jSLE group of renal involvement, cutaneous symptoms, oral ulcers, NP manifestations, AIHA, and anti-dsDNA positivity. A significant proportion of patients in the jSLE group had damage, most prominently in the renal domain. Our findings might support different genetic/environmental backgrounds for these 2 subgroups.

Objective. The aim was to assess the characteristics of PsA, find out how well the disease is controlled in real life, demonstrate the treatments and identify the unmet needs. Methods. The PsA registry of Turkey is a multicentre Web-based registry established in 2014 and including 32 rheumatology centres. Detailed data regarding demographics for skin and joint disease, disease activity assessments and treatment choices were collected. Results. One thousand and eighty-one patients (64.7% women) with a mean (S.D.) PsA duration of 5.8 (6.7) years were enrolled. The most frequent type of PsA was polyarticular [437 (40.5%)], followed by oligoarticular [407 (37.7%)] and axial disease [372 (34.4%)]. The mean (S.D.) swollen and tender joint counts were 1.7 (3) and 3.6 (4.8), respectively. Of these patients, 38.6% were on conventional synthetic DMARD monotherapy, 7.1% were on anti-TNF monotherapy, and 22.5% were using anti-TNF plus conventional synthetic DMARD combinations. According to DAS28, 86 (12.4%) patients had high and 105 (15.2%) had moderate disease activity. Low disease activity was achieved in 317 (45.7%) patients, and 185 (26.7%) were in remission. Minimal disease activity data could be calculated in 247 patients, 105 of whom (42.5%) had minimal disease activity. The major differences among sexes were that women were older and had less frequent axial disease, more fatigue, higher HAQ scores and less remission. Conclusion. The PsA registry of Turkey had similarities with previously published registries, supporting its external validity. The finding that women had more fatigue and worse functioning as well as the high percentage of active disease state highlight the unmet need in treatment of PsA.

Abstract Behçet’s disease (BD) is a rare, chronic, inflammatory disorder characterized by multisystemic vasculitis including mucocutaneous, neurologic, and ophthalmic involvement. Our aim is to compare vascular endothelial growth factor (VEGF) and soluble vascular endothelial growth factor receptor-1 (sVEGFR-1) levels in BD, among the patients having or not having organ involvement, disease activation and especially vascular involvement. Fifty-five patients with BD, 25 of which were accompanied by vascular involvement, and 31 control subjects were included in the study. Disease activity was assessed with the Turkish version of Behçet Disease Current Activity Form (BDCAF) and active vasculitis lesions at the time of study were recorded. Age at diagnosis was 32.2 ± 4.6, while the mean duration of BD was 96.3 (72.3) months. The median for BDCAF score was 2.0 (range 0, 3.0), and 29 (52%) of patients had active BD. The serum VEGF and sVEGFR-1 levels in patients with BD were significantly higher than that in controls [(298 (338.5) pg/mL; 93 (93.5) pg/mL in patients and 136.2 (73) pg/mL; 56.5 (48.5) pg/mL in controls, respectively, p < .001 for both values] while difference in VEGF/sVEGFR-1 ratio was obtained close to borderline of significance (p = .03). Our study is the first report indicating elevated serum VEGF, sVEGFR-1, and more importantly VEGF/sVEGFR-1 ratio could play an important role in the development of trombosis in BD. VEGF and/or sVEGFR-1 should not be evaluated independently in the same patient group and the ratio of these two parameters is a more important indicator, especially in the evaluation of BD especially with vascular involvement together with the duration of disease.

Abstract Background. Oxidative stress may play an important role in rheumatoid arthritis (RA) etiopathogenesis. The thiol group is a very strong antioxidant. In this study, we aimed to investigate the presence of oxidative stress in patients with RA by evaluating thiol/disulfide homeostasis. Material and methods. A total of 50 female RA patients and 50 healthy female controls were included in this study. Thiol and disulfide values were calculated utilizing novel methods. Results. Native thiol (p < 0.001) and total thiol (p < 0.001) levels of RA patients were significantly lower compared to values in the control group. However, the disulfide (p < 0.001) levels of RA patients were strongly higher than in healthy individuals. A negative correlation was found between thiol and disease activity score-28 among the patients, whereas a positive correlation was found between disulfide and disease activity score-28 among the patients. Conclusion. We found that the thiol–disulfide rate deteriorated in RA patients, with the proportion of disulfide increasing. There is a strong correlation between the decrease in thiol levels, increase in disulfide levels and the disease activity scores.

Abstract Rheumatoid arthritis (RA) prevalence increases with age and old people are special patient population. The recognition of functional disability related to RA could be challenging in elderly patients because aging itself and potential co-morbid disease may also cause functional disability. In this study, we aimed to look at the correlation between disease activity and functional disability in elderly RA patients. Elderly RA patients, ≥65 years old at their routine visits were included in the study. The composite ‘disease activity score’ in 28 joints (DAS-28) was used to determine disease activity groups. Health assessment questionnaire (HAQ) scores were calculated to describe the functional disability and compared across the disease activity groups. Two hundred and fifty-eight RA patients with the mean age of 71 ± 5 (65–90) and a total disease duration of 8.4 ± 8.5 (.5–50) years were recruited. The proportion of patients with high and moderate disease activity was 70%. HAQ scores were significantly correlated with disease activity (p < .05). Functional disability estimated by HAQ was correlated with disease activity in elderly patients with RA

Psoriatic arthritis (PsA) may affect different joints, including the spine. The prevalence of spinal involvement is variable depending on the definition and a subset of patients have been identified in cohorts that do not have clinical features of axial disease and yet have imaging findings. Still, there is not a consensus on how and when to screen axial disease. In this study, we aimed to investigate factors associated with being underdiagnosed for axial psoriatic arthritis (axPsA) and its impacts on outcomes. Disease features and outcomes of axPsA according to the physician (n = 415) were compared with patients with imaging findings only (sacroiliitis fulfilling the modified New York criteria, n = 112), using data from a real-life PsA registry. Patients with imaging findings only were more frequently women (83/220 (37.7%) vs 29/122 (23.8%); p = 0.008). This group also had higher peripheral disease activity (imaging only vs clinical AxPsA: mean (SD) tender joint count 5.3 (6.1) vs 3.3 (4.7), swollen joint count 1.9 (2.9) vs 1.2 (2.4); p < 0.001 for both comparisons) and was less often treated using TNF inhibitors (16.1 vs 38.2%; p < 0.001) than patients who were classified as axPsA. Patient-reported outcomes were similar in both groups. PsA patients, especially women with more severe peripheral disease, have a higher risk of being underdiagnosed for axPsA. The severity of peripheral symptoms may be a risk factor to mask the spinal features of PsA.

Fatigue is a symptom that affects the 40–80% of patients with rheumatoid arthritis (RA) and impairs the quality of life. The aim of this study was to assess multidimensional fatigue scales, the Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire (BRAF-MDQ) and the Bristol Rheumatoid Arthritis Fatigue Numerical Rating Scale (BRAF-NRS) and to evaluate their relationship with disease activity in Turkish RA patients. The study included 180 patients with RA. The Disease Activity Score (DAS28), Clinical Disease Activity Index (CDAI), and Simplified Disease Activity Index (SDAI) were used to evaluate disease activity. The participants comprised of 142 females and 38 males. The mean ± standard deviations of DAS28, CDAI, and SDAI were 3 ± 1.24, 9.51 ± 7.96, and 10.5 ± 8.38 respectively. All scales except the emotional subscale were correlated with disease activity. The emotional subscale correlated with CDAI and SDAI but not with DAS28. The results of the study indicated that fatigue and disease activity were correlated. Fatigue is a symptom that impairs the quality of life but it can be easily coped with by controlling disease activity. Thus, it should be assessed in a multidimensional perspective.

Immunoglobulin A vasculitis (Henoch-Schönlein purpura) is an immunoglobulin A-mediated vasculitis of unknown cause, which is characterized by non-thrombocytopenic purpura, arthralgia, abdominal pain, and glomerulonephritis. It most commonly occurs in children, and usually follows a benign course. It can also affect adults and is probably related to malignancy. In this article, we report a case of rectal adenocarcinoma in an immunoglobulin A vasculitis with renal involvement.

Introduction The aim of the study was to investigate whether there is a relationship between the European League Against Rheumatism (EULAR) outcome measures and quality of life (QoL), fatigue, anxiety and depression in patients with pSS and to define determinants which could affect quality of life. Material and methods The study included 105 pSS patients and 72 age/sex-matched healthy controls (HCs). Cross-sectional clinical data were collected, including the Hospital Anxiety and Depression Scale (HADS), the Multidimensional Assessment of Fatigue (MAF) scale, the Short Form (SF-36), EULAR Sjögren’s syndrome disease activity index (ESSDAI) and EULAR Sjögren’s syndrome patient reported index (ESSPRI). Results The SF-36 scores were significantly lower and anxiety, depression and fatigue scores were significantly higher in the pSS group than in the control group (all p-value < 0.05). ESSDAI was negatively correlated with SF-36 scores and positively with MAF. ESSPRI was negatively correlated with SF-36 scores except for the mental health subdimension, and a positive correlation was determined with MAF, HADS-A and HADS-D. Multiple linear regression analysis revealed that HADS-A, HADS-D, MAF, ESSPRI and ESSDAI were associated with most SF-36 subscales. Conclusions The results of this study provide further evidence supporting the use of ESSDAI and ESSPRI in daily practice. Quality of life was diminished in patients with pSS and was associated with different symptoms. This should be taken into account when managing patients with pSS.
