The present study aimed to evaluate efficacy, safety, and treatment adherence associated with the initial use of TNFi therapy in biologic naive patients diagnosed with LoAS. Patients whose age of onset was ≥ 45 years and < 45 years were classified as having LoAS and YoAS, respectively, based on the age of symptom onset.

Body mass index does not affect response of rituximab in patients with rheumatoid arthritis: results from the TURKBİO registry.

Background/aim: Adipose tissue produces several inflammatory mediators. Thus, obesity affects the disease course and the responses to the antirheumatic agents in inflammatory diseases. The aim of the study was to determine whether the body mass index (BMI) is involved in the response to rituximab in rheumatoid arthritis (RA).

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.

Functional exercise capacity in patients with ankylosing spondylitis.

Objective: This study aimed to measure the functional exercise capacity of patients with ankylosing spondylitis (AS) with the incremental shuttle walk test (ISWT), and to determine the factors associated with this test.

Methods: This cross-sectional study included 54 patients with AS (29 males, 25 females). The ISWT was performed to determine functional exercise capacity.

Unintentional Monotherapy in Rheumatoid Arthritis Patients Receiving Tofacitinib and Drug Survival Rate of Tofacitinib.

Objective: To determine the rate of unintentional monotherapy (UM; switching to monotherapy from combination therapy of patients' own volition) in rheumatoid arthritis patients receiving tofacitinib and to evaluate tofacitinib survival rate.

Methods: This national, multicenter study included patients' data from the TURKBIO Registry. Demographics, clinical characteristics, disease duration and activity, comorbidities, and treatments were analyzed.

A lower frequency of inflammatory back pain in male patients with ankylosing spondylitis compared with female patients.

In routine rheumatology practice, we noticed that a significant number of male ankylosing spondylitis (AS) patients did not experience inflammatory back pain (IBP). Based on this observation, we aimed to investigate the prevalence of IBP in male AS patients and compare it to that in female patients. Patients with AS who fulfilled the modified New York criteria were subjected to a face-to-face interview with a standardized questionnaire that addressed the IBP components based on the Berlin criteria.

Quantitative analysis of JAK/STAT signaling pathway in patients of inflammatory skin disorders.

Background: Inflammatory skin diseases (ISDs), are characterized by dysregulated activation of innate and adaptive immune systems, with inflammatory cytokines playing a crucial role in their pathogenesis.

Objectives: This study aimed to investigate the involvement of Janus kinase/signal transduction and activator of transcription (JAK/STAT) signaling pathway in the pathogenesis of ISDs.

Methods: The study analyzed a total of 117 skin biopsies, comprising 31 from pyoderma gangrenosum (PG), 25 from hidradenitis suppurativa (HS), 35 from psoriasis patients, and 26 from control subjects.

The Effect of Vedolizumab on Spondyloarthritis Symptoms in a Cohort of Inflammatory Bowel Disease Patients.

Objective: Vedolizumab is a novel anti-inflammatory molecule that is currently being used in the treatment of refractory inflammatory bowel disease. The mode of action is inhibiting the binding of activated T lymphocytes to the adhesion molecule 1 of intestinal mucosal cells. Due to its local effect, systemic immunosuppression is not expected, and this may have a negative effect on the extra-intestinal symptoms of inflammatory bowel disease, particularly spondyloarthritis.
