| Popis: | Relationships between aetiology, various risk factors (such as neutropenia, catheter insertion, endoscopy, therapy with corticosteroids, therapeutic use of antimicrobials, antibiotic prophylaxis, source of infection), symptomatology and outcome were studied in 553 monomicrobial bacteraemic episodes in cancer patients observed within 7 years at the National Cancer Institute of the Slovak Republic. The ratio of gram-positive to gram-negative bacteraemia was 1:1 (43.5% vs 43.8%), and yeasts caused 7.2% of monomicrobial episodes. The highest mortality was associated with Pseudomonas aeruginosa (19.2%), non-albicans Candida yeasts (25%) and Bacteroides fragilis (22.6%). Independent risk factors for particular pathogens were investigated by a computerized logistic regression model. The only independent risk factor for staphylococcal and enterococcal bacteraemia was vascular catheter insertion (OR = 1.95 and 2.05, CI = 95%, P = 0.035 and 0.044, respectively). However, there were no independent specific risk significant factors for viridans streptococcal bacteraemia and bacteraemia due to Enterobacteriaceae or Ps. aeruginosa. Neutropenia was found to be an independent predictor for development of Acinetobacter spp. bacteraemia (OR = 3.84, CI = 95%, P = 0.044). Prior therapy with third-generation cephalosporines was a predictive, independent risk factor for the development of fungaemia (OR = 1.99, CI = 95%, P = 0.028) but not of enterococcal bacteraemia. We also did not observe any association between prior therapy with imipenem and Stenotrophomonas maltophilia bacteraemias. Multivariate analysis confirmed that fungaemia may be independently associated with higher mortality than bacteraemia caused by Enterobacteriaceae and staphylococci. However, the mortality of fungaemia was statistically no different from that of Ps. aeruginosa, Stenotrophomonas spp. and viridans streptococci bacteraemias. |
