Abstract:

Background:

Colonisation with Burkholderia cepacia complex in patients with cystic fibrosis (CF) has been associated with adverse outcomes. The aim of the present study was to determine the actuarial survival of CF patients colonized with B. cepacia and to evaluate the efficacy of the Royal Prince Alfred Hospital segregation policy. A secondary aim was to characterize the specific genomovars and strains of B. cepacia isolated in an Australian clinic. Methods:

Retrospective review of spirometric and microbiological data on all patients colonized with B. cepacia. Each B. cepacia-colonized subject was matched with three case-control subjects. Phenotype and genomovar typing, random amplified polymorphic DNA strain type and B. cepacia epidemic strain marker analyses were performed. The effect of B. cepacia colonization on transplant-free survival was estimated by Cox's proportional hazards regression using the entire clinic population. Results:

Fifteen patients were colonized with B. cepacia, of whom six (40%) had died from CF-related disease by August 1998, compared with 30 of 173 (17.3%) of the entire clinic population. Cepacia status had a significant adverse effect on survival, with a hazard ratio of 2.16 (95% confidence interval 1.0–4.69; P = 0.05). The outcome was variable in subgroups of B. cepacia. Discussion:

Colonization with B. cepacia had a significant adverse effect on survival within the study population. Genomovar and strain typing contributed usefully in accessing the effectiveness of the hospital's segregation policy in preventing cross-colonization.
