Objective: IL23R polymorphisms have been shown to have a significant association with ankylosing spondylitis (AS). To date, these studies have been restricted to Caucasian patients with AS. Our study addresses this relationship in Korean patients with AS.
Methods: A total of 451 patients with AS and 392 ethnically matched healthy controls were enrolled. All patients were native Koreans with AS satisfying the modified New York criteria. In total, 10 single nucleotide polymorphisms (SNP) within the IL-23R gene cluster were genotyped.
Results: No IL-23R SNP were found to be associated with AS in Koreans.
Conclusion: The association of IL23R and AS that is seen in Caucasian patients with AS is not present in Korean patients with AS.

IL-23R (interleukin-23 receptor), found on the surface of several immune cells, plays a key role in the immune system. Indeed, this process is not limited to the inflammatory response but also plays a role in the adaptive immune response. The binding between IL-23R and its specific ligand, the interleukin 23, initiates a number of specific signals by modulating both properties and behavior of immune cells.

Background: The Assessment of SpondyloArthritis international Society Health Index (ASAS HI) is a novel questionnaire of global functioning for patients with axial spondyloarthritis (SpA).
Objective: The objective was to assess the construct validity, discriminatory ability and responsiveness of ASAS HI in relation to patient-reported outcome measures (PROMs), MRI and radiography.
Methods: Data from two longitudinal studies with tumour necrosis factor inhibitor (TNFi) initiation (novel MRI And biomarkers in Golimumab-treated patients with axial spondyloarthritis (MANGO): n=45) respectively tapering (Dose adjustment of Biological treatment in patients with SpA (DOBIS): n=106) were used.

Previous studies have suggested an association between autoimmune diseases (AIDs) and the risk of prostate cancer (PCa). However, the causal relationship between AID and PCa remained unclear. The purpose of this study was to investigate the causal association between 3 common AIDs, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and ankylosing spondylitis (AS), and the risk of PCa.

This study aims to elucidate the potential genetic commonalities between metabolic syndrome (MetS) and rheumatic diseases through a disease interactome network, according to publicly available large-scale genome-wide association studies (GWAS). The analysis included linkage disequilibrium score regression analysis, cross trait meta-analysis and colocalisation analysis to identify common genetic overlap. Using modular partitioning, the network-based association between the two disease proteins in the protein-protein interaction set was divided and quantified.

Background: Patients with Rheumatic and Musculoskeletal Diseases, including axial spondyloarthritis (axSpA), may suffer from stressors like pain and functional impairments leading to limitations in their self-perceived health status. The COping with Rheumatic Stressors (CORS) questionnaire was developed to analyze how patients cope with these stressors. The CORS is currently not available in German.
