abstract: In a prospective study, a two-week course of antibiotics (cloxacillin 2 g/4 h plus amikacin 7.5 mg/kg/12 h) was evaluated in the therapy of right-sided infective endocarditis in intravenous drug users (IVDU). All IVDU admitted to hospital during the study period who fulfilled the strict criteria for diagnosis of infective endocarditis were analysed. A subgroup of patients with right-sided endocarditis caused by Staphylococcus aureus who had a good prognosis were selected as being eligible for the two-week course of treatment. In a total of 139 episodes of infective endocarditis in IVDU, 72 (51.8%) cases were eligible for the two-week treatment. Of this group, 67 were cured, 4 needed prolongation of treatment to cure the infection and 1 died in hospital of respiratory distress syndrome on day 10 of treatment. In patients not eligible for the two-week treatment, the mortality was higher (24.2% versus 0.7%; p = 0.00015). Drug toxicity in the treated group was low. It can be concluded that administration of cloxacillin and amikacin parenterally for 14 consecutive days was successful in the therapy of right-sided endocarditis in IVDU.
