Abstract
• To determine the efficacy of "short-course" therapy (Staphylococcus aureuscatheter-associated bacteremia, 13 patients were prospectively followed up for at least three months after completion of therapy. A single patient relapsed after 28 days with endocarditis. No clinical or microbiological predictors of relapse could be identified, and coexistent medical conditions associated with some degree of immunosuppression did not appear to predispose to relapse. The results of this study and a review of the literature indicate that short-course therapy for uncomplicatedS aureuscatheter-associated bacteremia has a relapse rate of only 5% to 10% and, therefore, is reasonable therapy for this condition. The majority of relapses are endocarditis and occur within ten weeks after completion of therapy. Close follow-up during this period is essential. (Arch Intern Med1989;149:533-536)
