Special Issue Information

Dear Colleagues,

Autoimmune rheumatic diseases represent a major problem for physicians and researchers alike. Autoimmune diseases have seen a significant increase in incidence and prevalence all over the world. The etiology behind this augmented prevalence and incidence of autoimmune rheumatic diseases is not known and poses a major problem for physicians and researchers alike. Additionally, the incidence and prevalence of multiple autoimmunity are increasing, and it is currently seen in many patients. However, even as autoimmune rheumatic diseases are increasing in prevalence and incidence, novel therapeutic agents are becoming available. These agents offer new hope for successful treatment and better prognosis for patients and physicians alike. In particular, biologic agents have had a major impact on the treatment of autoimmune rheumatic diseases. JAK inhibitors also offer hope for treatment and better quality of life in patients. Recently, cell-based therapies such as CAR-T cell treatment have become part of the armamentarium for the treatment of autoimmune rheumatic diseases. Novel research has allowed the identification of major pathways involved in the pathogenesis of autoimmune rheumatic diseases. For this Special Issue, we welcome any paper related to the pathogenesis or treatment of autoimmune rheumatic diseases.

Receptor–Ligand Biomarker Profile in Ankylosing Spondylitis: Associations Between AXL/MERTK Expression, Circulating GAS6 and Protein S Levels, and Disease Activity

Abstract
(1) Background: Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease associated with immune dysregulation. The TYRO3, AXL, and MER (TAM) signaling pathway, comprising AXL receptor tyrosine kinase (AXL), MER tyrosine kinase (MERTK), growth arrest-specific 6 (GAS6), and [...] Read more.
(1) Background: Ankylosing spondylitis (AS) is a chronic inflammatory rheumatic disease associated with immune dysregulation. The TYRO3, AXL, and MER (TAM) signaling pathway, comprising AXL receptor tyrosine kinase (AXL), MER tyrosine kinase (MERTK), growth arrest-specific 6 (GAS6), and Protein S, is a key regulator of immune homeostasis. This study investigated these receptor–ligand components in patients with AS. (2) Methods: A total of 45 patients with AS and 44 healthy controls were enrolled. Serum GAS6 and Protein S levels were measured by ELISA, and AXL and MERTK expression levels were analyzed by RT-qPCR. Clinical and inflammatory parameters were also evaluated. (3) Results: ESR, CRP, and IL-6 levels were significantly higher, whereas Protein S levels were significantly lower in patients with AS than in controls. No significant differences were observed in GAS6, AXL, or MERTK expression levels, although lower expression trends were detected in patients. Logistic regression analysis identified CRP, IL-6, Protein S, and AXL expression as variables independently associated with AS. ROC analysis demonstrated significant discriminatory performance for AXL expression. (4) Conclusions: Alterations in the TAM signaling pathway, particularly reduced Protein S levels and altered AXL expression, may contribute to immune dysregulation and persistent inflammation in AS.

Systemic sclerosis-associated interstitial lung disease (SSc-ILD) is the leading cause of mortality in patients with systemic sclerosis and a major clinical challenge due to its heterogeneous presentation and variable disease course. Reliable biomarkers may improve disease assessment, risk stratification, and therapeutic decision-making. This narrative review summarizes current evidence on established and emerging serum and molecular biomarkers in SSc-ILD and their potential clinical applications. Recent advances have shifted the focus from single-marker assessment toward integrated biomarker profiling, reflecting the complex pathogenesis of pulmonary fibrosis. KL-6 and surfactant protein D (SP-D) have been associated with pulmonary involvement and radiographic features of SSc-ILD. Inflammatory mediators, including interleukin-6 (IL-6), and autoantibodies such as anti-topoisomerase I (anti-Scl-70) have been associated with disease severity and an increased risk of pulmonary progression. Emerging biomarkers related to epithelial injury, extracellular matrix remodelling, and vascular dysfunction may provide additional insights into the biological mechanisms underlying SSc-ILD. Current evidence highlights the potential of circulating and molecular biomarkers to refine risk stratification and prognostic assessment in SSc-ILD. Prospective validation and methodological standardization remain necessary to determine their clinical utility and potential integration into personalized disease management. Full article

Psoriatic arthritis (PsA) is a systemic autoimmune inflammatory disease affecting both the joints and the skin, with the potential involvement of multiple organ systems. A hallmark feature of PsA is enthesitis—inflammation at the sites where tendons and ligaments insert into bone—which arises from a combination of mechanical stress and immune-mediated inflammation. Another defining characteristic of the disease is the paradoxical coexistence of bone erosion and new bone formation, distinguishing it from other inflammatory arthritides. The therapeutic landscape of PsA has evolved considerably over time. Non-steroidal anti-inflammatory drugs (NSAIDs) remain a cornerstone of symptom management, while conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), such as methotrexate, are widely used to control disease progression. The introduction of biologic agents has revolutionized PsA management, with TNF inhibitors, IL-17 inhibitors, and IL-23 inhibitors demonstrating efficacy across a broad range of clinical manifestations. More recently, targeted synthetic small molecules—including JAK inhibitors and TYK2 inhibitors—have expanded the armamentarium of available therapies. The overarching goals of treatment in PsA include the suppression of the underlying inflammatory process and the prevention of structural joint damage. The impact of each therapeutic option on cutaneous psoriasis is an additional and important consideration that guides individualized treatment options. Full article

Granulocyte-macrophage colony-stimulating factor (GM-CSF) has emerged as a key cytokine in the pathogenesis of rheumatoid arthritis, an autoimmune disease distinguished by synovial inflammation and progressive joint destruction. GM-CSF orchestrates the activation, proliferation, and differentiation of myeloid cells (mainly macrophages and neutrophils) thereby sustaining the pro-inflammatory synovial milieu. Recent advances in monoclonal antibody immunotherapy have enabled selective inhibition of GM-CSF or its receptor. Clinical data on several monoclonal antibodies are presented, focusing on their pharmacodynamic properties and efficacy results documented in phase II and III clinical studies. Cumulative evidence supports GM-CSF inhibition as a compelling strategy for modulating inflammation and improving clinical outcomes in rheumatoid arthritis. Full article
