Age-Related Differences Between Juvenile and Adult Autoimmune Inflammatory Myopathies.

Background: Clinical features and prognosis of autoimmune inflammatory myopathies (AIMs) can vary depending on the age of disease onset. The aim of this study was to compare the demographic characteristics, clinical features, laboratory findings, and long-term prognosis of juvenile and adult AIMs.

Methods: Patients diagnosed with AIM between 2009 and 2023 in the pediatric rheumatology and rheumatology departments of our hospital were included in this medical records review study.

Obesity might not alter tofacitinib drug survival in rheumatoid arthritis patients.

Introduction: Obese rheumatoid arthritis (RA) patients often show reduced responses to traditional treatments, including TNF inhibitors (TNFi). Considering the different mechanisms of action it is important to evaluate the efficacy of tofacitinib in obese patients. This study aims to explore the impact of obesity on the drug survival of tofacitinib in RA patients.

Non-criteria autoantibodies in antiphospholipid syndrome may be associated with underlying disease activity.

Background: Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by persistent antiphospholipid antibodies (aPLs) with arterial and venous thrombosis and/or pregnancy morbidity. In recent years, several studies have highlighted the potential role of non-criteria aPL in diagnosing APS patients.

Aim: This study aimed to determine the association of the presence of non-criteria aPL antibodies to the clinical and laboratory features of patients with a diagnosis of APS.

A single-center rheumatology experience of sarcoidosis: observations from 70 patients.

Background: The aim of this study is to determine the demographic, clinical and laboratory characteristics of the patients who followed up with the diagnosis of sarcoidosis, to investigate the distribution frequency of rheumatological findings and to examine the disease management from the perspective of rheumatology.

Methods: Patients who were followed up with the diagnosis of sarcoidosis in the rheumatology clinic of Ankara City Hospital between November 2019 and November 2022 were evaluated. Demographic, clinical, radiological, serological, laboratory, and histopathological findings, and rheumatological, systemic, and locomotor system examination findings of the patients were obtained from the medical data registered in the hospital.

Rheumatology experience with FDG PET / CT in inflammation of unknown origin: a single - centre report for determining factors associated with diagnostic precision.

Unlabelled: BACKGROUND / AIM: The use of PET / CT is becoming more common in the elucidation of inflammatory processes in which the underlying cause cannot be determined by conventional examinations. Although PET / CT is an effective method for detecting inflammatory foci, the precise diagnosis may not be obtained in all cases. In addition, considering factors such as radiation exposure and cost, it becomes important to identify patients who can get results with PET / CT.

Tofacitinib experience in patients with enteropathic arthritis.

The JAK-STAT pathway is involved in the pathogenesis of both the inflammatory bowel disease (IBD) and spondyloarthropathy group of diseases. The purpose of this study was to evaluate the effectiveness of tofacitinib, a Janus kinase inhibitor, in the treatment of enteropathic arthritis (EA). The study included seven patients, four from the authors' follow-up and three from the literature.

Effects of breast milk on Behçet's disease clinical features.

Background: The etiology of Behçet's disease (BD) is not clearly known, however, abnormal activity in T helper (Th) 1, Th 17, and regulatory T cells (Treg) has critical importance in pathogenesis. It has been shown that the intestinal microbiome can be effective in the modulation of these immune abnormalities in BD patients. Breastfeeding increases the maturation of the infant's intestinal permeability by affecting the newborn's immature intestinal microbiome and metagenome.

COVID-19 disease frequency, risk factors, and re-infection rates in patients with autoimmune rheumatic disease receiving rituximab.

Introduction: Rituximab, which is used in autoimmune rheumatic diseases (ARD), can cause both an increased risk of development of COVID-19 disease and re-infection due to its potent and long-acting immunosuppression. So, we aimed to evaluate the frequency, risk factors and re-infection rates of COVID-19 in ARD patients receiving rituximab.

Methods: A single-center retrospective study was performed with patients receiving rituximab for ARD in 12 months before the onset of COVID-19 in Turkey.

Effects of sulfasalazine in axial spondyloarthritis on COVID-19 outcomes: real-life data from a single center.

Introduction: Compared to biological agents, little is known about the impact of sulfasalazine therapy on COVID-19 outcomes in patients with Axial Spondyloarthritis (AxSpA). Therefore, we aimed to evaluate the COVID-19 severity in AxSpAs receiving sulfasalazine and biologic-agent.

Materials And Methods: A total of 219 SARS-CoV-2 positive AxSpA patients were retrospectively analyzed.

COVID-19 course in granulomatosis with polyangiitis: single center experience with review of the literature.

Background: Coronavirus disease 2019 (COVID-19) shares some clinical features with new-onset granulomatosis with polyangiitis (GPA) or GPA flare that may lead to a challenge in differential diagnosis. To date, little is known whether GPA can be induced by COVID-19. Herein, we aimed to seek the frequency and mortality rates of COVID-19 in our GPA cohort, and along with the literature cases, to evaluate clinical features and treatments of GPA patients with COVID-19.

A single-center COVID-19 vaccine experience with CoronaVac and BNT162b2 in familial Mediterranean fever patients.

Aim: To determine frequency of adverse events and attacks related to vaccination in recipients of CoronaVac and BNT162b2 in familial Mediterranean fever (FMF) patients, and to search whether history of prior COVID-19 or a booster dose increases occurrence of adverse events/attacks.

Methods: FMF patients were surveyed for administration of any COVID-19 vaccine and vaccine-related adverse events or FMF attacks. Demographic, clinical, vaccine-related data, history of COVID-19 infection before or after vaccination, adherence to FMF treatment during vaccination were collected.

Performance of the systemic lupus erythematosus risk probability index in a cohort of undifferentiated connective tissue disease.

Objectives: We sought to evaluate the performance of the SLE Risk Probability Index (SLERPI) for identification of SLE in a large cohort of patients with UCTD.

Methods: The SLERPI was applied in a cohort of patients who met classification criteria for UCTD and did not fulfil any classification criteria for other defined CTD including SLE. Patients with a SLERPI score of >7 were 'diagnosed' as SLE.
