The challenges of diagnosing myositis are numerous, with many tests resulting in false positives and negatives for autoantibody levels. Researchers recently compared a line blot array currently being used in research with the Oklahoma Medical Research Foundation Myositis panel, which is used in clinical testing. They found some patients were positive according to the research test, but negative according to the clinical test…
A recent study investigated the possible differences in nailfold videocapillaroscopy in four types of inflammatory myopathies. Researchers observed giant capillaries, disorganization and major capillary loss in dermatomyositis and overlap myositis patients, finding dermatomyositis and overlap myositis imaging was different from that of antisynthetase syndrome and immune-mediated necrotizing myopathy…
Monosodium urate (MSU) crystal formation, deposition and gout flares frequently affect joints that have been damaged or are affected by osteoarthritis. These researchers examined the effects of human cartilage homogenates on MSU crystallization and MSU crystal-induced inflammation…
NEW YORK (Reuters Health)—New consensus-based recommendations from the European League Against Rheumatism (EULAR) address the management of Sjögren’s syndrome with topical and systemic therapies. Sjögren’s syndrome presents with a broad spectrum of clinical manifestations and autoantibodies, including antinuclear antibodies (the most frequently detected), anti-Ro/SS-A (the most specific) and cryoglobulins and hypocomplementemia (the main prognostic markers)….
A recent study from Brazil suggests lupus nephritis patients who receive renal transplant have a high five-year survival rate. Researchers found the presence of venous thrombosis and antiphospholipid syndrome, but not viral infection, were important predictors of renal graft loss in these patients…
