title: Burkholderia cepacia bacteremia: a retrospective analysis of 70 episodes.
abstract: Burkholderia cepacia, a widespread gram-negative environmental bacillus associated with nosocomial infections, is considered to be of relatively low virulence and rarely to cause invasive disease. We retrospectively analyzed the risk factors, clinical manifestations, antimicrobial susceptibilities, and prognostic factors of B. cepacia bacteremia cases. From 1982 through 1995, 70 episodes of bacteremia due to B. cepacia occurred in 52 patients at the National Taiwan University Hospital. The overall case fatality rate was 11%. Sixty-four episodes were nosocomial infections. The common predisposing conditions were stay in an intensive care unit (61%) and invasive procedures, including urinary catheter (54%), intravenous catheter (70%), and intubation (57%). Three episodes involved polymicrobial bacteremia. In 41 episodes in which the infectious focus was identified, the respiratory tract was the most common portal of entry (17/41) followed by intravascular catheters (11/41). Most strains tested were susceptible to ceftazidime (95%), piperacillin (93%), minocycline (85%), and cefotaxime (82%); but most were resistant to aminoglycosides, tetracycline, carbenicillin, and ticarcillin. For empirical therapy of B. cepacia bacteremia, ceftazidime or piperacillin should be the drug of choice.
