We report a case of necrotizing tracheobronchitis with rheumatoid arthritis. A 64 year-old-man presented with dry cough and was initially diagnosed with community-acquired pneumonia. The patient was admitted; he received initial antibiotic treatment. The treatment was effective and the symptoms worsened. Bronchoscopy was performed for more thorough examination. It showed that white and soft tissues were on the trachea-bronchus. Transbronchial biopsy of the tracheal lesions revealed necrotic tissue with squamous metaplasia and inflammatory cells. Whereas, symmetrical arthralgia of multiple joints of the limbs was noted and rheumatoid factor and anti-cyclic citrullinated peptide antibody of levels were high. According to these results, the patient was diagnosed with rheumatoid arthritis. In this case, necrotizing tracheobronchitis occurred as a result of systemic inflammation associated with rheumatoid arthritis. An acute exacerbation of the patient's respiratory condition was treated with steroid therapy. Tracheal findings and respiratory symptoms were improved by steroid therapy.

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).

Introduction: Psoriatic arthritis (PsA) is a chronic inflammatory arthropathy associated with cutaneous psoriasis (PsO), first defined by Moll and Wright. Initially perceived as relatively benign, PsA is now recognized for its chronic, progressive, and destructive nature, significantly impacting patients' quality of life, similar to Rheumatoid Arthritis (RA). Globally, PsA represents about 20% of cases in early arthritis clinics, posing diagnostic and management challenges.
