An uncommon, but well recognised complication of Ankylosing Spondylitis (AS) is spondylodiscitis, a destructive discovertebral lesion also called the Andersson lesion. We describe six cases, with variable clinical presentation and radiological appearance. Two had multiple lesions, in one patient spondylodiscitis was the presenting symptom of AS. None had a history of even a minor trauma. Prognosis was good with conservative treatment including NSAID's, rest, and physiotherapy. In two cases histopathology was studied and suggested sterile inflammation as the main etiologic factor. The literature is reviewed regarding the mechanisms that may contribute to these lesions: mainly inflammatory like increasing enthesopathy or mainly mechanical like pseudoarthrosis about a fracture site. It may be that both mechanisms can result in similar destructive intervertebral disc lesions.

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).

IL-17A, referred to as IL-17, is the founding member of a family of pro-inflammatory cytokines, including IL-17B, IL-17C, IL-17D, IL-17E (or IL-25), and IL-17F, which act via receptors IL-17RA to IL-17RE, and elicit potent cellular responses that impact diverse diseases. IL-17's interactions with various cytokines include forming a heterodimer with IL-17F and being stimulated by IL-23's activation of Th17 cells, which can lead to inflammation and autoimmunity. IL-17 is implicated in infectious diseases and inflammatory disorders such as rheumatoid arthritis and psoriasis, promoting neutrophil recruitment and anti-bacterial immunity, but potentially exacerbating fungal and viral infections, revealing its dual role as protective and pathologic.

Objectives: This study aims to elucidate the microbial signatures associated with autoimmune diseases, particularly systemic lupus erythematosus (SLE) and inflammatory bowel disease (IBD), compared with colorectal cancer (CRC), to identify unique biomarkers and shared microbial mechanisms that could inform specific treatment protocols.
Methods: We analysed metagenomic datasets from patient cohorts with six autoimmune conditions-SLE, IBD, multiple sclerosis, myasthenia gravis, Graves' disease and ankylosing spondylitis-contrasting these with CRC metagenomes to delineate disease-specific microbial profiles. The study focused on identifying predictive biomarkers from species profiles and functional genes, integrating protein-protein interaction analyses to explore effector-like proteins and their targets in key signalling pathways.

Background: Many factors, such as decreased spinal mobility, pain, and dysfunction can affect gait parameters in patients with ankylosing spondylitis. The purpose of this study was to investigate the effects of plantar fascia enthesitis and disease-specific measurements on gait parameters in patients with ankylosing spondylitis.
Methods: The Win-Track platform was used to evaluate spatiotemporal parameters in patients with ankylosing spondylitis and in healthy controls.

Introduction: Ankylosing Spondylitis (AS) presents a complex inflammatory condition with significant impact on patients' lives. Despite advancements in understanding its pathogenesis, comprehensive elucidation remains elusive. This study investigates the outcomes of corrective spine surgery in AS patients, aiming to optimize management strategies.
