Ankylosing Spondylitis (AS) Overview

Ankylosing Spondylitis is a chronic, immune-mediated spondyloarthropathy strongly associated with the HLA-B27 gene, characterized by enthesitis, sacroiliitis, and progressive spinal fusion driven by severe TNF and IL-17 axis dysregulation. It manifests as insidious, inflammatory back pain and persistent morning stiffness that improves with physical activity. Extramusculoskeletal signs include acute anterior uveitis, extensive plaque psoriasis, and subclinical inflammatory bowel disease. Diagnosis combines clinical presentation, elevated acute-phase reactants, and sacroiliac joint inflammation caught on pelvic MRI. Severity and structural damage are quantified using validated ASDAS and BASDAI metrics. While oral NSAIDs remain the first-line symptomatic cornerstone, newly updated clinical guidelines enforce a specialized, treat-to-target strategy using advanced targeted therapies for refractory or erosive disease. Frontline biologics feature dual IL-17A and IL-17F inhibitors like bimekizumab and next-generation oral JAK inhibitors like upadacitinib. Importantly, management algorithms prioritize patient-specific comorbidities: for patients with concurrent active uveitis or severe structural bowel disease, monoclonal TNF inhibitors are heavily prioritized, whereas IL-17 blockers are strictly avoided in active intestinal flares. Supervised physical therapy and structured spinal mobility monitoring are mandated alongside these advanced biologics to limit long-term bony ankylosis, minimize elevated cardiovascular comorbidity risks, and maximize physical functional capacity.
