Background/aim: The objective of this study is to evaluate the clinical presentations and adverse outcomes of Coronavirus Disease 2019 (COVID-19) in patients with systemic sclerosis (SSc) and assess the impact of SSc features on the clinical course of COVID-19. Materials and methods: In this multicenter, retrospective study, SSc patients with COVID-19 were included. Clinical features of SSc, along with detailed COVID-19 data, were extracted from medical records and patient interviews. Results: The study included 112 patients (mean age 51.4 ± 12.8 years; 90.2% female). SSc-associated interstitial lung disease (ILD) was evident in 57.1% of the patients. The findings revealed hospitalization in 25.5%, respiratory support in 16.3%, intensive care unit admission in 3.6%, and a mortality rate of 2.7% among SSc patients with COVID-19. Risk factors for respiratory failure, identified through univariate analysis, included ILD (OR: 7.49, 95% CI: 1.63-34.46), =1 comorbidity (OR: 4.55, 95% CI: 1.39-14.88), a higher physician global assessment score at the last outpatient visit (OR 2.73, 95% CI: 1.22-6.10), and the use of mycophenolate at the time of infection (OR: 5.16, 95 %CI: 1.79-14.99). Notably, =1 comorbidity emerged as the sole significant predictor of the need for respiratory support in COVID-19 (OR: 5.78, 95% CI: 1.14-29.23). In the early post-COVID-19 period, 17% of patients reported the progression of the Raynaud phenomenon, and 10.6% developed new digital ulcers. Furthermore, progression or new onset of dyspnea and cough were detected in 28.3% and 11.4% of patients, respectively. Conclusion: This study suggests a potential association between adverse outcomes of COVID-19 and SSc-related ILD, severe disease activity, and the use of mycophenolate. Additionally, it highlights that having comorbidities is an independent risk factor for the need for respiratory support in COVID-19 cases. [ABSTRACT FROM AUTHOR]

Background/aim: To investigate the impact of smoking on disease activity, treatment retention, and response in patients with ankylosing spondylitis (AS) treated with their first tumor necrosis factor-a inhibitor (TNFi). Materials and methods: AS patients who started their first TNFi treatment for the active axial disease (BASDAI ≥ 4) from TURKBIO Registry were included. Treatment response of smoker (current and ex-smokers) and nonsmoker (never smoker) patients were primarily evaluated as achievement of BASDAI50 or improvement in BASDAI at least 20 mm at 3 months and 6 months compared to baseline. Results: There were 322 patients with AS (60% male, 59% smoker, mean age: 38.3 years). The median follow-up time was 2.8 years (Q1-Q3: 1.3-3.8), and disease duration was 3.5 years (Q1-Q3: 0.7-8.2). Smokers had male predominance (p < 0.001), lower ESR (p = 0.03), higher BASDAI (p = 0.02), BASFI (p = 0.05), HAQ-AS (p = 0.007), and ASDAS-CRP (p = 0.04) compared with nonsmokers at baseline. In the multivariate analysis, male gender [OR 2.7 (95%CI 1.4-5), p = 0.002], and concomitant conventional synthetic disease-modifying antirheumatic drug use [OR 2.4 (95%CI 1.1-5.2), p = 0.03] were associated with better treatment response. There was an association of male gender [HR 2.4 (95%CI 1.6-3.7), p < 0.001], older age (≥30years) [HR 1.8 (95%CI 1.1-2.8), p = 0.01], and response to treatment [HR 1.8 (95%CI 1.2-2.9), p = 0.008] with better treatment retention. No impact of smoking status was found on treatment retention and response in univariate and multivariate analyses. Conclusion: This study suggested that smoking was associated with poorer patient-reported outcomes in biologic naïve AS patients initiating their first TNFi treatment, but it had no impact on the TNFi treatment response and retention rate.

Objectives: The study aimed to investigate the variation of brain-derived neurotrophic factor (BDNF) levels following acute exercise in patients with rheumatoid arthritis (RA). Patients and methods: This cross-sectional study was conducted with 88 participants (25 males, 63 females; mean age: 45.1±8.3 years; range, 18 to 65 years) between July 2020 and May 2021. Of the participants, 44 were RA patients, and 44 were age-and sex-matched healthy controls. Aerobic exercise was utilized in all participants for a single session. Depression and anxiety levels were evaluated with the Beck Depression Inventory and Hospital Anxiety and Depression Scale. Blood samples were collected from all subjects before and immediately after the intervention. Results: Serum BDNF levels (both baseline and after exercise) were similar in the RA and control groups. Although serum BDNF levels significantly decreased in both groups after aerobic exercise (Wilcoxon rank p<0.05), ΔBDNF levels were significantly higher in the RA group than in the control group (p=0.047). Additionally, ΔBDNF levels were significantly correlated with the Hospital Anxiety and Depression Scale scores in the RA group (p<0.05) but not in the control group. Conclusion: A single bout of exercise may effectively decrease serum BDNF levels in patients with RA and healthy subjects. The long-term effect of exercise on BDNF levels should be investigated in prospective studies. [ABSTRACT FROM AUTHOR]

Objective: The coronavirus disease 2019 pandemic has been resulting in increased hospital occupancy rates. Rheumatic patients cannot still reach to hospitals, or they hesitate about going to a hospital even they are able to reach. We aimed to show the effect of the first wave of coronavirus disease 2019 pandemic on the treatment of biological disease-modifying anti-rheumatic drugs in patients with rheumatoid arthritis or spondyloarthritis. Methods: Patients were divided into three groups as follows: pre-pandemic (Pre-p: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within 6 months before March 11, 2020); post-pandemic A (Post-p A: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within the first 6 months after March 11, 2020); post-pandemic B (Post-p B: starting on biological disease-modifying anti-rheumatic drug therapy for the first time within the second 6 months). Results: The number of rheumatoid arthritis patients in the Post-p A and B groups decreased by 51% and 48%, respectively, as compared to the Pre-p group similar rates of reduction were also determined in the number of spondyloarthritis patients. The rates of tofacitinib and abatacept use increased in rheumatoid arthritis patients in Post-p period. Conclusion: The number of rheumatoid arthritis and spondyloarthritis patients starting on biological disease-modifying anti-rheumatic drugs for the first time decreased during the first year of the coronavirus disease 2019 pandemic.

Objectives: Achilles tendinopathy can be noticed in both acromegaly and ankylosing spondylitis (AS). Acromegaly patients presenting with tendinopathy findings may be confused with AS findings. In this study, sonoelastrographic findings of Achilles tendon are explored in patients with AS and acromegaly.Methods: 25 patients with AS, 30 patients with acromegaly, and 18 healthy controls were enrolled in the study. Achilles tendon was evaluated by sonoelastography in all the study participants.Results: The thickness of Achilles tendon in neutral positions was higher in acromegaly patients than those in AS patients. The sonoelastography measurement of Achilles tendon was increased in acromegaly patients when compared to the control group and AS patients.Conclusion: The thickness of Achilles tendon can increase in patients with acromegaly and AS. However, the sonoelastographic features of Achilles tendon can be similar in patients with AS and acromegaly. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study is to examine the changes in physical activity level, fatigue, depression, and sleep quality in patients with Behçet’s disease during the COVID-19 pandemic. Methods: The study was designed as an online questionnaire applied to individuals who are being followed up with the diagnosis of Behçet’s disease in the rheumatology department. Data were collected using multiple scales including International Physical Activity Questionnaire (IPAQ), Fatigue Severity Scale (FSS), Beck Depression Inventory (BDI), Pittsburg Sleep Quality Index (PSQI), and Visual Analogue Scale (VAS) to evaluate physical activity level, fatigue, depression, sleep quality, and pain, respectively. Results: Sixteen patients diagnosed with Behçet’s disease were included in the study. No statistically significant difference was observed between the IPAQ, FSS, BDI, PSQI, and VAS assessment scores before COVID-19 and during COVID-19 period (P > .05 for all). Conclusion: Thinking of the negative effects of aggressive clinical symptoms, Behçet’s disease patients should be supported in physical activity and psychosocial status [ABSTRACT FROM AUTHOR]

Objective: TURKBIO registry, established in 2011, is the first nationwide biological database in Turkey. This study aimed to provide an overview of TURKBIO data collected by June 2018. Methods: The registry included adult patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), nonradiographic axial spondyloarthritis (nr-AxSpA), and psoriatic arthritis (PsA). Demographic and clinical features, disease activity markers, and other follow-up parameters, current and previous treatments, and adverse events were registered electronically at each visit using open-source software. The registration of patient-reported outcome measures was carried out electronically by the patients using touch screens. Results: TURKBIO registry included a total of 41,145 treatment series with biologicals. There were 2,588 patients with axSpA (2,459 AS and 129 nr-axSpA), 2,036 with RA, and 428 with PsA. The total number of patients, including those with other diagnoses, was 5,718. In the follow-up period, the number of patients and also visits steadily increased by years. The yearly mean number of visits per patient was found to be 2.3. Significant improvements in disease activity and health assessment parameters were observed following the biological treatments. Biologics were often given in combination with a conventional synthetic disease-modifying antirheumatic drug in patients with RA. Infections were the most commonly seen adverse events, followed by allergic reactions. Tuberculosis was observed in 12 patients, malignancy in 18, and treatment-related mortality in 31. Conclusion: TURKBIO provided a valuable real-life experience with the use of biologics in rheumatic diseases in Turkey. [ABSTRACT FROM AUTHOR]

Objectives: This study aims to define serum levels of netrin-1 and netrin receptors in patients with fibromyalgia (FM) and osteoarthritis (OA). Patients and methods: This cross-sectional study was conducted with a total of 150 female participants (mean age: 47.2±16.1 years; range, 18 to 89 years) at Fırat University between June 2016 and December 2016. The participants were evaluated in three groups: the FM group with 50 patients, the OA group with 50 patients, and the control group, which included 50 healthy volunteers. Netrin-1, netrin receptors (DCC, UNC5B, and UNC5D), interleukin (IL)-6, IL-10, and IL-17 levels were analyzed by the enzyme-linked immunosorbent assay from the serum samples of the participants. Results: The level of serum netrin-1 was significantly lower in the FM group than in the control and OA groups (p<0.01 and p<0.001, respectively). However, the difference between patients with OA and healthy controls in terms of netrin-1 was not statistically significant (p>0.05). In addition, serum levels of netrin receptors and cytokines in the FM group were similar to the control group (p>0.05). However, serum DCC, UNC5D, IL-6, and IL-10 levels were higher in the OA group compared to the control group (p<0.001, p<0.05, p<0.01, and p<0.001, respectively). Conclusion: Serum netrin-1 level is suppressed in FM, which suggests that netrin-1 is influential in FM pathogenesis. [ABSTRACT FROM AUTHOR]

Objective: The knowledge of physicians about complementary and alternative medicine (CAM) applications is limited. However, especially in chronic diseases, patients and their relatives can often refer to CAM applications. Rheumatic diseases are chronic in nature presenting with a wide clinical spectrum. Despite developing treatment options, achieving treatment goals may not always be possible. For this reason, patients seek different treatment and use traditional and complementary medicine. The aim of this study was to investigate causes, consequences, and the frequency of applying to CAM in rheumatic diseases. Methods: Ninety-five patients admitted to the rheumatology outpatient clinic were enrolled in the study. Health assessment questionnaire and short-form-36 were used to determine the quality of life of patients. Anxiety and depression symptoms were screened by the Hospital Anxiety and Depression scale, a questionnaire that was filled-in by the patients themselves. Also, patients were questioned about their place of residence, level of education, diagnosis, CAM modality types, application reasons, and outcomes. Chi-square test was used to analyze categorical data. Parametric data were analyzed using Student t-test, and nonparametric data were analyzed using Mann-Whitney U test. Results: Thirty-two of our patients had applied to CAM modalities (phytotherapy [34.45%], cupping therapy [21.8%], acupuncture [12.5%], hirudotherapy [12.5%], food supplement [12.5%], and ozone treatment [6.25%]). Only 31.3% of the patients informed their doctors about CAM applications. 47.8% of fibromyalgia patients and 29.2% of patients with inflammatory rheumatic diseases had applied to CAM. Gender, working status, income level, smoking, and alcohol habits were not associated with the application to CAM. However, none of the residents of the village, 14.3% of the residents of the district center, and 41.1% of the residents of the city center had applied to CAM modality. The rate of applying to CAM was 18.2% for those who cannot read and write. The application ratio of CAM is over 40% among secondary school, high school, and university graduates. Conclusion: Among patients with rheumatic diseases, application to CAM is quite common. Very few patients inform their physicians about applying to CAM. Contrary to what is presumed, the rate of applying CAM applications is lower among those living in rural areas and with low education levels. [ABSTRACT FROM AUTHOR]

Amaç: Sistemik sklerozda (SSk) oto-antikorlar hastalığın tanısında, alt tiplerinin ve prognozun belirlenmesinde ve organ tutulumlarının öngörülmesinde kullanılmaktadır. SSk hastalarında hastalığa spesifik oto-antikorlar (anti-sentromer antikor, anti-Scl-70 antikor ve anti-RNA polimeraz II antikor) yanında spesifik olmayan oto-antikorlar da saptanmaktadır. Çalışmamızın, erken SSk hastalarında genişletilmiş bir profilde oto-antikorların sıklığını, erken dönem ve takipte gelişen organ tutulumları ile ilişkisini araştırmaktır. Yöntem: Çalışmaya ACR/EULAR 2013 sınıflama kriterlerini karşılayan ve hastalık süresi <3 yıl olan erken SSk hastaları alındı. Hastaların ANA ölçümleri HEp-20-10/primat karaciğer mozaiği indirekt immünofloresan (IIF) ve geniş panel oto-antikor ölçümü için SSc (Nucleoli) Profile EuroLine (Euroimmun, Lübeck, Almanya) kitleri kullanıldı. Bulgular: Yüz hastadan 93'ü IIF ile ANA için pozitifti. Anti-Scl70 ab en sık saptanan (%41) oto-antikor olurken, bunu %27 ile anti-sentromer ab (ACA) ve %15 sıklıkla RNAPIII izledi. Otuz iki hastada çoklu otoantikor pozitifliği ve 53 hastada tek pozitiflik (26'sı anti-Scl70, 16'sı ACA, 6'sı anti-RNAPIII, 1 anti-Ku ab, 1 anti-PM/Scl100, 2 anti-PM/Scl75 ve 1 anti-Ro52) saptandı. SSk'ye özgü otoantikorlar arasında, anti-Scl70 ve anti-RNAPIII antikorları en yüksek birliktelik gösterdi ve 4 hastada pozitifti. SSk'ye özgü otoantikorlar için tek veya çoklu boyaması olan hastalar arasında majör organ tutulumları açısından fark yoktu (tümü için p>0,05). Hastaların 4 yıllık takibi sonucunda 80 hastanın verilerine ulaşıldı. Hastaların 3'ünün takipten çıktığı ve birinin öldüğü saptandı. Daha önce organ tutulumu saptanmayan hastaların takip sırasında 5'inde İAH, 1'inde PAH ve 3'ünde dijital ülserin yeni geliştiği bulundu. İAH gelişen yaygın deri tutulumlu hastalarda Scl-70 saptanırken, İAH gelişen sınırlı deri tutulumlu hastalarda CENPA/B, Ro52 ve anti-ku antikorlarının ikili pozitiflikleri saptandı. Sonuç: Çalışmamızın sonuçlarına göre SSk'da spesifik otoantikorlar nispeten sık olmasına rağmen, hastaların çoğunluğunda çoklu otoantikor pozitiflikleri görülmüştür. Çoklu oto-antikor pozitiflikleri SSk-spesifik oto-antikorların beklenen organ tutulumlarında farklılığa farklılığa yol açabilir. [ABSTRACT FROM AUTHOR]
