Introduction: Autoimmune diseases have increasing importance in modern medicine and cover increasing areas of medicine including rheumatoid arthritis interstitial lung disease.
Aim: The main aims of this study are to evaluate the association of some autoimmune variables in patients with rheumatoid arthritis interstitial lung disease.
Methods: A retrospective study was conducted from files of patients with rheumatoid arthritis interstitial lung disease. A total of 210 files of intended patients were included in this study. The study was conducted in rehabilitation clinics at Royal Medical Services. Study variables include some demographic variables such as age, and gender; clinical variables such as disease related factors such as duration, diagnostic criteria; predictive factors such as rheumatoid factors, smoking, and MTX treatment. Data were collected and entered into excel spreadsheet to create raw data. The analysis of data was carried out using the software SPSS version 21. Descriptive statistical parameters were used to describe data including means and standard deviations for continuous variables. Frequency and percentages were used to describe categorized variables such as gender. The relationships between study variables were computed using independent T test, and One Way ANOVA test. Significance was determined if α≤ 0.05.
Results: The prevalence of RA-ILD was 3.70%. The study participants were subdivided into two groups according to MTX treatment, non-exposed group and exposed group. There were significant relationships between MTX treatment and study variables including gender, age of (rheumatoid arthritis) RA onset, smoking, and rheumatoid factor (RF). The progression of RA-ILD was impacted by gender, age of (rheumatoid arthritis) RA onset, smoking, rheumatoid factor (RF), and MTX treatment.
Conclusion: Patients with RA and RA-ILD follow similar clinical characteristics in other studies except MTX treatment, but this can't be generalized because of small number of RA-ILD patients.

Rheumatoid arthritis (RA) is one of the most common systemic autoimmune inflammatory diseases, with a progressive etiology that results in serious complications and a higher chance of early death. Visfatin, an adipokine, is correlated with disease pathologic features and becomes a key biomarker and therapeutic target for RA. This study aimed to evaluate the anti-arthritic activity of metformin (an antidiabetic drug with anti-inflammatory activities) and methotrexate (the first choice for disease-modifying antirheumatic drugs in RA, with diverse adverse effects) in complete Freund's adjuvant (CFA)-induced arthritis in female rats.

Introduction: Our aim was to investigate the insufficiently understood differences in the immune system between anti-citrullinated peptide antibody (ACPA)-positive (ACPA) and ACPA-negative (ACPA) early rheumatoid arthritis (eRA) patients.
Methods: We performed multiple cytokine assays using sera from drug-naïve ACPA and ACPA eRA patients. Additionally, we conducted single-cell RNA sequencing of CD45 cells from peripheral blood samples to analyze and compare the distribution and functional characteristics of the cell subsets based on the ACPA status.

This pilot study investigates distinctive features within the nail-enthesis complex among Psoriatic arthritis (PsA), Psoriasis (PSO), Rheumatoid Arthrit is (RA), and Healthy Control (HC) groups, utilizing a combined approach of ultrasound (US) and nailfold videocapillaroscopy (NVC). Clinical assessments and comprehensive US and NVC evaluations of the nail-enthesis complex were conducted on 72 subjects (18 PsA, 16 PSO, 19 RA, 19 HC). Unsupervised clustering models and factor analysis were employed to identify patterns and interrelationships between US and NVC parameters.

Introduction: Periodontitis is associated with rheumatoid arthritis (RA). One hypothesis posits that this connection arises from the formation of autoantibodies against citrullinated proteins (ACPA) in inflamed gums, possibly triggered by . We previously demonstrated an increased antibody response to arginine gingipains (anti-Rgp IgG), not only in individuals with severe periodontitis compared to controls, but in RA versus controls, with an association to ACPA.

Autoimmune rheumatic diseases (ARDs) are a heterogeneous group of conditions characterized by excessive and misdirected immune responses against the body's own musculoskeletal tissues. Their exact aetiology remains unclear, with genetic, demographic, behavioural and environmental factors implicated in disease onset. One prominent hypothesis for the initial breach of immune tolerance (leading to autoimmunity) is molecular mimicry, which describes structural or sequence similarities between human and microbial proteins (mimotopes).
