Celecoxib-related renal papillary necrosis.

Selective cyclooxygenase 2 (COX-2) inhibitors are known to affect renal prostaglandins (epoprostenol and dinoprostone), which are at least in part COX-2 dependent. Consequently, adverse events including hypertension, peripheral edema, hypercalemia, hyponatremia, and acute renal failure have been reported to occur with the new COX-2-specific inhibitors. This case report posits celecoxib as a likely cause of renal papillary necrosis and alerts physicians to the possibility of this additional renal complication with COX-2-specific inhibitors.

Localized versus systemic vasculitis: diagnosis and management.

Localized vasculitis restricted to a specific anatomic site or organ is often histologically indistinguishable from more severe, systemic forms of vasculitis. By definition, localized vasculitis involves blood vessels within a confined vascular distribution or single organ without clinical evidence of generalized inflammation. Important factors that determine treatment and prognosis, in what appears initially to be a localized process, include histopathologic type, organ site, and the presence of systemic inflammatory markers and symptoms. The major issue is whether single organ vasculitis is actually an isolated form of the disease in which case surgical excision is curative, or whether the single organ involvement is simply a precursor of more threatening systemic vasculitis. The Birmingham Vasculitis Activity Score is a valuable tool to identify those patients with concurrent systemic involvement. The physician's recognition of a localized versus systemic vasculitic process is important in terms of making the correct diagnosis, prescribing treatment, and arranging appropriate clinical follow-up.

Inverse correlation of each functional status scale of the SF-36 with degree of disease activity in systemic lupus erythematosus (m-SLAM).

OBJECTIVES: To compare systemic lupus erythematosus (SLE) disease activity measured by a modified Systemic Lupus Activity Measure (m-SLAM) with functional/health status measured by the SF-36 questionnaire. PATIENTS AND METHODS: m-SLAM and SF-36 scores were obtained on 71 SLE patients during 242 clinic visits over 15 months. Patients were stratified into disease activity groups (m-SLAM <2 = remission; 2-4 = mild; 4-6 = moderate; >6 = severe). Mean SF-36 group scores were compared by analysis of variance (ANOVA). RESULTS: Two hundred and nineteen m-SLAM and SF-36 scores were completed. The disease activity groups correlated inversely with the SF-36 scores in all eight subscales, i.e. the patients' perceived health, as assessed by the SF-36, correlated with their disease activity level as measured by the m-SLAM. Inverse correlation of SLAM activity groups with all eight SF-36 subscales was highly statistically significant. CONCLUSION: The significant inverse correlation of the m-SLAM with all domains of the SF-36 in this study provides potentially useful information for evaluating patients with SLE.
