Infection prophylaxis in acute leukaemia patients: comparison of selective and total antimicrobial decontamination of the gastrointestinal tract.
In a retrospective study, total antimicrobial decontamination with strict reverse isolation (ITD) and selective decontamination without isolation (SD) were compared as means of preventing infection in patients with acute leukaemia. Thirty patients were treated with ITD and 34 patients with SD. The surveillance cultures indicated that aerobic gram-negative bacilli and yeast could be equally eliminated effectively in both the groups. The anaerobic flora was only minimally influenced by SD. The incidence of acquired infections was 1.17 per patient in group ITD as compared to 0.85 in group SD. In group ITD, acquired bacterial infections were mostly caused by gram-negative bacilli (63%) whereas in the group SD these microorganisms accounted only for 25% of the infections. In group SD the total number of fever days was significantly lower and the mean duration of pyrexial episodes was substantially shorter. The results indicate that SD is an effective and inexpensive method for preventing gram-negative infections and might be at least as effective as ITD.
