Is the use of secukinumab after anti-TNF therapy greater than expected for the risk of developing inflammatory bowel disease?

OBJECTIVE: In this study, our objective was to present real-life data on the incidence of inflammatory bowel disease (IBD) among patients receiving secukinumab treatment. METHODS: The study consisted of 209 patients who had prior exposure to anti-tumor necrosis factor (TNF) or were biologically naive. Patients with a pre-existing history of IBD were excluded from the study. RESULTS: Of the 209 patients in the study, 176 (84.3%) had ankylosing spondylitis, while 33 (15.7%) had psoriatic arthritis. 112 (53.6%) patients had prior exposure to at least one anti-TNF treatment before initiating secukinumab. IBD developed in 10 (4.8%) of the 209 patients. The incidence of IBD among patients who initiated secukinumab as their first biologic agent was 1%. For patients who had previously received any anti-TNF treatment and subsequently transitioned to secukinumab, the incidence of IBD was 8% (p=0.018, odds ratio (OR): 8.38, 95% CI: 1.04-67.45). A mean of 3.67 months (±4.3) after anti-TNF use, whereas IBD symptoms developed in the biologically naive patient after 15 months. CONCLUSION: Our study observed IBD incidence in 4.8% of patients using secukinumab. Patients who initiated secukinumab after previous anti-TNF treatment exhibited a significantly higher rate and risk of developing IBD. The onset of IBD occurred earlier in these patients (mean 3.67 months), whereas a single case of IBD showed a longer duration (15 months). Further studies with larger patient numbers are warranted to provide a more comprehensive understanding of our findings.

Evaluation of discontinuation for adverse events of JAK inhibitors and bDMARDs in an international collaboration of rheumatoid arthritis registers (the 'JAK-pot' study).

BACKGROUND: In a clinical trial setting, patients with rheumatoid arthritis (RA) taking the Janus kinase inhibitor (JAKi) tofacitinib demonstrated higher adverse events rates compared with those taking the tumour necrosis factor inhibitors (TNFi) adalimumab or etanercept. OBJECTIVE: Compare treatment discontinuations for adverse events (AEs) among second-line therapies in an international real-world RA population. METHODS: Patients initiating JAKi, TNFi or a biological with another mode of action (OMA) from 17 registers participating in the 'JAK-pot' collaboration were included. The primary outcome was the rate of treatment discontinuation due to AEs. We used unadjusted and adjusted cause-specific Cox proportional hazard models to compare treatment discontinuations for AEs among treatment groups by class, but also evaluating separately the specific type of JAKi. RESULTS: Of the 46 913 treatment courses included, 12 523 were JAKi (43% baricitinib, 40% tofacitinib, 15% upadacitinib, 2% filgotinib), 23 391 TNFi and 10 999 OMA. The adjusted cause-specific hazard rate of treatment discontinuation for AEs was similar for TNFi versus JAKi (1.00, 95% CI 0.92 to 1.10) and higher for OMA versus JAKi (1.11, 95% CI 1.01 to 1.23), lower with TNFi compared with tofacitinib (0.81, 95% CI 0.71 to 0.90), but higher for TNFi versus baricitinib (1.15, 95% CI 1.01 to 1.30) and lower for TNFi versus JAKi in patients 65 or older with at least one cardiovascular risk factor (0.79, 95% CI 0.65 to 0.97). CONCLUSION: While JAKi overall were not associated with more treatment discontinuations for AEs, subgroup analyses suggest varying patterns with specific JAKi, such as tofacitinib, compared with TNFi. However, these observations should be interpreted cautiously, given the observational study design.

Does obesity affect treatment response to secukinumab and survival in ankylosing spondylitis? Real-life data from the TURKBIO Registry.

OBJECTIVES: The aim of this study was to evaluate the impact of obesity on the treatment response to secukinumab and drug survival rate in patients with ankylosing spondylitis (AS). METHODS: We performed an observational cohort study that included AS patients based on the biological drug database in Turkey (TURKBIO) Registry between 2018 and 2021. The patients were divided into three groups: normal [body mass index (BMI) < 25 kg/m2], overweight (BMI: 25-30 kg/m2), and obese (BMI ≥ 30 kg/m2). Disease activity was evaluated at baseline, 3, 6, and 12 months. Drug retention rates at 12 months were also investigated. RESULTS: There were 166 AS patients using secukinumab (56.6% male, mean age: 44.9 ± 11.6 years). The median follow-up time was 17.2 (3-33.2) months. Forty-eight (28.9%) patients were obese. The mean age was higher in the obese group than in others (P = .003). There was no statistically significant difference in Bath Ankylosing Spondylitis Disease Activity Index 50, Assessment of SpondyloArthritis international Society 20 (ASAS20), ASAS40, Ankylosing Spondylitis Disease Activity Score (ASDAS) low disease activity, and ASDAS clinically important improvement responses between the three groups at 3, 6, and 12 months, although they were numerically lower in obese patients. Drug retention rates at 12 months were similar in all groups (P > .05). CONCLUSIONS: This study suggested that obesity did not affect secukinumab treatment response and drug retention in AS patients.

Tocilizumab as a first line biologic agent in rheumatoid arthritis patients with inadequate response to disease-modifying anti-rheumatic drugs: real life experience from the TReasure Registry.

OBJECTIVES: To evaluate the retention rate, treatment response and safety of tocilizumab (TCZ) as first-line biologic treatment in rheumatoid arthritis (RA) patients with inadequate response to disease-modifying anti-rheumatic drugs (DMARD-IR). METHODS: The TReasure Registry is a multicentre, web-based registry of RA and spondyloarthritis patients across Turkey. DMARD-IR RA patients who received TCZ as first-line biologic treatment were included in this registry for efficacy and safety. Demographic and clinical data, treatments, and adverse events were collected. Drug retention rate was estimated using Kaplan-Meier analysis. RESULTS: Among 642 RA patients who ever used TCZ, 258 DMARD-IR RA patients (male/female: 18.2%/81.8%, mean age, 54.41 years) received TCZ as first-line biologic. The median disease duration was 97 (range, 60-179) months and the median TCZ treatment duration was 15 (range, 6-28) months. At the 6th and 12th months of TCZ treatment, the decrease in disease activity scores from baseline was significant. The Kaplan-Meier analysis revealed the retention rate of TCZ at the 12th, 24th, 36th, and 60th months as 81.1%, 73.8%, 66.2%, and 63.6%, respectively. Fifty-seven (22%) patients discontinued TCZ; the main reason being primary or secondary inefficacy (n=29). CONCLUSIONS: Over 80% drug retention rate at 12th month of TCZ treatment in this real-world study was concordant with previously conducted TCZ clinical studies. Significant reductions not only in the disease activity score-28 but also in the simplified disease activity index (SDAI) and clinical disease activity index (CDAI) scores, along with health assessment questionnaire (HAQ) scores, supported the impact of TCZ in RA management with a good safety profile.

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.

Extended autoantibody panel in Turkish patients with early-stage systemic sclerosis: Coexpressions and their influences on clinical phenotypes.

BACKGROUND/AIM: To investigate the frequency and clinical relevance of an extended autoantibody profile in patients with systemic sclerosis (SSc). MATERIALS AND METHODS: In this cross-sectional study, serum from 100 consecutive patients was subjected to indirect immunofluorescence (IIF) (HEp-20-10/primate liver mosaic) and Systemic Sclerosis Profile by EUROIMMUN to evaluate anti-nuclear antibodies (ANA) and autoantibodies against 13 different autoantibodies in patients with SSc less than 3 years. RESULTS: Ninety-three of 100 patients were positive for ANA by IIF. Fifty-three patients showed single positivity, 26 anti-topoisomerase antibodies (anti-Scl70 ab), 16 anticentromere antibodies (ACAs), six anti-RNA polymerase III antibodies (anti-RNAPIII ab), one anti-Ku antibody, one anti-PM/Scl100 antibody, two anti-PM/Scl75 antibodies, one anti-Ro52 antibody, whereas 32 patients had multiple autoantibody positivities. Among classic SSc-specific autoantibodies, anti-Scl70 and anti-RNAPIII abs showed the highest cooccurrence (n = 4). One patient was simultaneously positive for anti-RNAPIII ab and ACA, and one was positive for ACA and anti-Scl70 ab. The clinical features were not statistically different between single and multiple autoantibody-positivity for classic SSc-specific autoantibodies (ACA, anti-Scl70 ab, and anti-RNAPIII ab), except for digital ulcer in the multiantibody positive ACA group (p = .019). CONCLUSION: Based on our results, coexpression of autoantibodies is not uncommon in SSc patients. Although autoantibodies specific to SSc in early disease show generally known clinical features, it remains to be investigated how the coexpression of autoantibodies will affect clinical presentation.

The impact of smoking on response to tumor necrosis factor-α inhibitor treatment in patients with ankylosing spondylitis.

BACKGROUND: 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-α inhibitor (TNFi). 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. DISCUSSION: 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.

Effects of acute aerobic exercise on brain-derived neurotrophic factor level in rheumatoid arthritis patients.

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.

Treatment of systemic sclerosis-associated digital ulcers: recommendations of the Turkish Society for Rheumatology.

OBJECTIVES: Digital ulcers (DUs) are associated with a significant burden in systemic sclerosis (SSc) by leading to severe pain, physical disability, and reduced quality of life. This effort aimed to develop recommendations of the Turkish Society for Rheumatology (TRD) on the management of DUs associated with SSc. METHODS: In the first meeting held in December 2020 with the participation of a task force consisting of 23 rheumatologists the scope of the recommendations and research questions were determined. A systematic literature review was conducted by 5 fellows and results were presented to the task force during the second meeting. The Oxford system was used to determine the level of evidence. The preliminary recommendations were discussed, modified, and voted by the task force and then by members of TRD via e-mail invitation allowing personalised access to a web-based questionnaire [SurveyMonkey®]. RESULTS: A total of 23 recommendations under 7 main headings were formulated covering non-pharmacological measures for the prevention of DUs and pharmacological treatments including vasodilators, anti-aggregants, antibiotics, wound care, pain control, and interventions including sympathectomy, botulinum toxin, and surgery. Risk factors, poor prognostic factors, prevention of DU and adverse effects of medical treatments were reported as 4 overarching principles. CONCLUSIONS: These evidence-based recommendations for the management of SSc-associated DUs were developed to provide a useful guide to all physicians who are involved in the care of patients with SSc, as well as to point out unmet needs in this field.

Effects of acute aerobic exercise on cytokines, klotho, irisin, and vascular endothelial growth factor responses in rheumatoid arthritis patients.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic inflammatory joint disease that causes cartilage and bone damage as well as disability.  AIMS : The aim of this study was to examine the effects of acute aerobic exercise on cytokines such as serum interleukin-6 (IL-6), interleukin-1ß (IL-1ß), Tumor Necrosis Factor-α (TNF-α) and irisin, vascular endothelial growth factor(VEGF) and klotho in RA patients.  METHODS: Forty RA patient and 40 healthy volunteers of the same age participated in this study. All participants walked on the treadmill for 30 minutes at 60-80% of maximal heart rate. Blood samples were taken before and immediately after the exercise. Serum levels of IL-6, IL1ß, TNF-α and irisin, VEGF and klotho were measured by enzyme-linked immunosorbent analysis.  RESULTS: Baseline levels of inflammatory cytokines, irisin, VEGF and klotho were found to be higher in RA patients compared to the control group. In both groups, there was an increase in serum klotho levels after exercise compared to baseline (p<0.05), while a decrease in IL1ß, TNF-α levels were observed. While serum VEGF level decreased in RA group, it increased in the control group(p<0.05). Irisin levels decreased in both groups. IL-6 level did not change in the control group, while it increased in RA group. A single exercise session had an acute anti-inflammatory effect in RA patients. CONCLUSION: It can be concluded that acute aerobic exercise can be beneficial for patients with RA through cytokine, irisin, klotho and VEGF levels, and also it can be safely implemented to the RA rehabilitation program for additional anti-inflammatory effects. Trial registration ClinicalTrials.gov: NCT04439682.

A national, multicenter, secondary data use study evaluating efficacy and retention of first-line biologic treatment with tocilizumab in patients with rheumatoid arthritis in real-life setting: results from TURKBIO registry.

Tocilizumab (TCZ) is a recombinant humanized monoclonal antibody that targets the IL-6 receptor. TCZ found to be efficacious and has a good tolerated safety profile in rheumatoid arthritis (RA) patients. The aim of this study was to describe the disease activity and retention rate in Turkish RA patients who were prescribed TCZ as first-line biologic treatment in a real-world setting. Secondary data obtained from adult RA patients' files was used in a multicenter and retrospective context. Clinical Disease Activity Index (CDAI), Disease Activity Score in 28 joints with ESR (DAS28-ESR), and retention rates of TCZ were evaluated at related time points. 130 patients (87.7% female) with a mean age of 53 years (SD; 15.0) were included in the study. Mean RA duration was 14 years and median duration of follow-up was 18.5 months. Number of patients with ongoing TCZ treatment at 6, 12, and 24 months were 121 (93%), 85 (65%), and 46 (35%), respectively. Remission rates at 6, 12, and 24 months per CDAI (< 2.8) and DAS28-ESR (< 2.6) scores were 61.5, 44.6, 30%, and 54.6, 40.8, 27.7%, respectively. Both CDAI and DAS28-ESR scores significantly improved at 6, 12 and 24 months (p < 0.001 for both). At 24 months, 23 patients (17.6%) discontinued TCZ, of whom majority (17/23) were due to unsatisfactory response. Retention rates of TCZ at 6, 12, and 24 months were 93, 84.3, and 72.2%, respectively. In this real-world study, TCZ as a first-line biologic therapy was found to be efficacious and showing high retention rates. These real-world study results are in line with previous randomized studies.

Serum netrin-1 and netrin receptor levels in fibromyalgia and osteoarthritis.

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 Firat 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.

A real-life analysis of patients with rheumatologic diseases on biological treatments: Data from TURKBIO Registry.

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 treat- ments, 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 con- ventional 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.

Tuberculin skin test before biologic and targeted therapies: does the same rule apply for all?

This study aimed to compare Tuberculin Skin Test (TST) and QuantiFERON®-TB Gold In-Tube (QFT-GIT) test in rheumatoid arthritis (RA) and spondyloarthritis (SpA) patients scheduled for biological and targeted synthetic disease modifying anti-rheumatic drugs (DMARDs) in a Bacillus Calmette-Guérin-vaccinated population. Adult RA (n = 206) and SpA (n = 392) patients from the TReasure database who had both TST and QFT-GIT prior to initiation of biological and targeted synthetic DMARDs were included in the study. Demographic and disease characteristics along with pre-biologic DMARD and steroid use were recorded. The distribution of TST and performance with respect to QFT-GIT were compared between RA and SpA groups. Pre-biologic conventional DMARD and steroid use was higher in the RA group. TST positivity rates were 44.2% in RA and 69.1% in SpA for a 5 mm cutoff (p < 0.001). Only 8.9% and 15% of the patients with RA and SpA, respectively, tested positive by QFT-GIT. The two tests poorly agreed in both groups at a TST cutoff of 5 mm and increasing the TST cutoff only slightly increased the agreement. Among age, sex, education and smoking status, pre-biologic steroid and conventional DMARD use, disease group, and QFT-GIT positivity, which were associated with a 5 mm or higher TST, only disease group (SpA) and QFT-GIT positivity remained significant in multiple logistic regression. TST positivity was more pronounced in SpA compared to that in RA and this was not explainable by pre-biologic DMARD and steroid use. The agreement of TST with QFT-GIT was poor in both groups. Using a 5 mm TST cutoff for both diseases could result in overestimating LTBI in SpA.

Complementary alternative medicine in rheumatic diseases: Causes, choices, and outcomes according to patients.

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.

Sonoelastrographic finding of Achilles tendon in patients with ankylosing spondylitis and acromegaly.

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.

Physical activity and psychosomatic status in patients with Behçet's disease during coronavirus disease pandem.

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.

Tofacitinib and metformin reduce the dermal thickness and fibrosis in mouse model of systemic sclerosis.

Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway is important in the process of inflammation and fibrosis. The adenosine 5'-monophosphate-activated protein kinase (AMPK) enzyme can affect JAK/STAT pathway. Tofacitinib is a pan-JAK inhibitör. Metformin activates AMPK enzyme. We aimed to investigate the therapeutic efficacy of tofacitinib and metformin on IL-17 and TGF-ß cytokines, skin fibrosis and inflammation in mouse model of systemic sclerosis (SSc). 40 Balb/c female mice were divided into 4 groups: (control, sham (BLM), tofacitinib and metformin). The mice in the tofacitinib group received oral tofacitinib (20 mg/kg/daily) and mice in the metformin group received oral metformin (50 mg/kg/day) for 28 days. At the end of 4th week, all groups of mice were decapitated and tissue samples were taken for analysis. Histopathological analysis of skin tissue was performed, and mRNA expressions of collagen 3A, IL-17 and TGF-ß were assessed by real-time PCR and ELISA. Repeated BLM injections had induced dermal fibrosis. Moreover, the tissue levels of collagen 3A, IL-17 and TGF-ß were elevated in the BLM group. Tofacitinib and metformin mitigated dermal fibrosis. They reduced dermal thickness and tissue collagen 3A, IL-17 and TGF-ß levels. Tofacitinib and metformin demonstrated anti-inflammatory and anti-fibrotic effects in the mouse model of SSc.

Real-world data on change in work productivity, activity impairment, and quality of life in patients with psoriatic arthritis under anti-TNF therapy: a postmarketing, noninterventional, observational study.

OBJECTIVES: To understand change in work productivity, activity impairment, quality of life (QoL), and disease activity in patients with psoriatic arthritis (PsA) receiving anti-tumor necrosis factor (anti-TNF) treatment. METHOD: One hundred twenty patients with PsA receiving anti-TNF therapy were recruited to this noninterventional, observational study. Work disability was assessed via the Work Productivity and Activity Impairment (WPAI) questionnaire and disease activity was calculated via the 28-joint Disease Activity Score using C-reactive protein (DAS28-CRP) and Disease Activity Index for Psoriatic Arthritis with 28 joints (DAPSA28) score. Patient-reported outcomes (PROs), from visual analog scores and Health Assessment Questionnaire-Disability Index scores, were evaluated to understand the clinical effectiveness at baseline and every 3 months until the month-9 final visit. The American College of Rheumatology (ACR)20/50/70 response criteria were assessed at month 9. RESULTS: A total of 120 patients (females, n = 73) were enrolled in the study. Mean (SD) age and disease duration were 41.6 ± 11.1 years and 6.9 ± 6.5 years, respectively. The most commonly used TNFα inhibitor was adalimumab (42.4%), followed by etanercept (25.8%). All WPAI questionnaire parameters were reduced at the follow-up visits compared with baseline (p < 0.001 for all). PROs and disease activity indicators (DAS28-CRP and DAPSA28) significantly improved during the course of anti-TNF treatments (p < 0.001 for all). Additionally, ACR20/50/70 responses were determined as 86.8%, 63.7%, and 41.8% of patients at the month-9 visit. CONCLUSIONS: The real-world data in PsA patients receiving anti-TNF treatment showed improvement in WPAI, QoL, and disease activity over 9 months of treatment. TRIAL REGISTRATION: NCT02028169 Key Points • Psoriatic arthritis (PsA), with debilitating effects on quality of life, occurs mostly in young adults and has negative impacts on employment status and work productivity. • Early PsA diagnosis and treat-to-target treatment strategies aim to reduce pain and joint damage, as well as improve work productivity. • Real-world data on the impact of treatment with anti-tumor necrosis factor (anti-TNF) agents on work productivity in PsA in the literature is scarce. • Our study of real-world data in patients with PsA receiving anti-TNF treatment showed improvement in work productivity, as well as in clinical and patient-reported outcomes.
