OBJECTIVE To confirm and extend the immunopathological evidence of effects of infliximab on the synovium in active spondyloarthropathy. METHODS Synovial biopsies obtained in patients with spondyloarthropathy at baseline and week 12 were stained and scored by two independent observers. Two study populations were evaluated: I, a cohort of 10 patients treated with 5 mg/kg infliximab at week 0, 2...

Activation of caspase-1 by NALP3 inflammasomes has been shown to be important in initiating acute gouty arthritis. The objectives of this study were to measure the levels of caspase-1 in synovial fluid in gout and various arthritides, and to elucidate the clinical significance of caspase-1 levels in synovial fluid. Caspase-1, IL-1β, IL-18, and uric acid were measured in synovial fluid from 112 ...

The purpose of this study was to analyze the expression of the two proinflammatory cytokines IL-20 and IL-24 and their shared receptors in rheumatoid arthritis and spondyloarthropathy. IL-20 was increased in plasma of rheumatoid arthritis patients compared with osteoarthritis patients and IL-24 was increased in synovial fluid and plasma of rheumatoid arthritis and spondyloarthropathy patients c...

introduction hypoparathyroidism might cause various musculoskeletal findings, resembling spondyloarthropathies. case presentation we described a 52-year-old woman, diagnosed as a case of undifferentiated spondyloarthropathy for ten years, who was unresponsive to classic anti-inflammatory therapies. she developed anterior ischemic optic neuropathy and had elevated muscle enzymes during the cours...

Lumbar spinal tumoral calcinosis and spinal epidural lipomatosis are rare conditions. We present a 70-year-old female patient with serology negative spondyloarthropathy who developed paresis due to tumoral calcinosis in the left facet joint between L5 and S1 levels and spinal epidural lipomatosis at L5 and S1 levels. Surgery was performed to excise the lesions en bloc. Neural decompression was ...

Behçet’s disease (BD) is a disease which has effects on different systems. Genital ulcer, aphthous stomatitis and iritis are characterized by triple symptom complex of BD. BD is considered to be a systemic vasculitis. BD was previously accepted in spondyloarthropathy (SSpA) group, but there are many reasons for not classifying BD as one of SSpA group. Ankylosing spondylitis (AS) is a prototype ...
