[Septic arthritis in systemic lupus erythematosus: a retrospective analysis of 6 cases].

Base on the clinical characteristics of septic arthritis in a group of systemic lupus erythematosus patients, this study has found out that high systemic lupus erythematosus disease activity index, leucopenia, high cumulative dose of glucocorticoid, methylprednisolone intravenous pulse therapy and joint cavity puncture were closely correlated with septic arthritis. Once septic arthritis is suspected, culture specimens should be collected and appropriate antibiotics are suggested immediately. Also, surgical drainage is a very useful approach.
