Abstract

Although home intravenous antibiotic therapy (HIAT) is increasingly being used for various infectious diseases, outpatient treatment of infective endocarditis (IE) is still uncommon. Recently, the American Heart Association recommended outpatient treatment of endocarditis only for infections with streptococci that are highly susceptible to penicillin. Herein, the experience with HIAT in patients with IE due to a diversity of pathogens is presented. During a 3-year period, 37 patients with IE who were in a stable condition and were cooperative were enrolled in a service for HIAT after completion of diagnostic procedures. Of the 37 patients, 21 were male; mean age was 64.3 years (range 20-87 years); in most cases (26/37), IE involved a native valve. Causative organisms were Streptococcus spp. (20), Staphylococcus spp. (10), Enterococcus spp. (2), Enterobacter spp. (1), and Erysipelothrix rhusiopathiae (1), while three were unknown. The most common antibiotics used were ceftriaxone and vancomycin. Almost three-quarters of the intravenous lines were peripheral. The mean duration of HIAT was 26.2 ± 8.5 days, with 92% of the patients cured by it. Most complications were minor. Six patients were rehospitalised and two of them required valve replacement. In half of the rehospitalised patients, the complication was unrelated to HIAT. Surprisingly, almost all of the complications necessitating rehospitalisation occurred in patients with streptococcal IE and most involved native valves. HIAT may be suitable for IE due to a diversity of pathogens and involving prosthetic as well as native heart valves, provided there are proper patient and antibiotic selections, good follow-up, and vigilant monitoring of complications.
