Comparison of Nosocomial Candidemia of Pediatric and Adult Cases in 2-Years Period at a Turkish University Hospital

Abstract

Objective: Although there are limited numerous reports of candidemia in adults, data on paediatrics are stil limeted. The aim of the present study was to compare the aetiology and risk factors of nosocomial candidemia among the paediatric and adults in our hospital. Materials and Methods: This study includes the patients hospitalised and diagnosed as fungemia at Ondokuz Mayis University Hospital between June 30, 2007 and June 30, 2009 whose blood cultures sent to our microbiology laboratory. After fungal growth was observed in blood cultures, the yeast cells were inoculated onto Saboraud glucose agar. The colonies were identified by conventional yeast identification methods and ID 32C yeast identification system according to the manifacturer's instructions. Results: During this period 51 paediatric and 69 adults were studied. The most common yeast form was Candida albicans (43.3%) followed by C. parapsilosis (25.0%) and C. tropicalis (17.5%). Although the non-albicans Candida species represent more than half (56.7%) of all candidemic cases C. albicans was the most common frequent etiologic agent. There was no statistically significant difference between patient age (paediatric and adult) and distribution of Candida species (p>0.05) Neoplasia (in adults) and prematurity (in paediatrics) were the main underlying diseases. Predisposing factors and mortality rates were not different among paediatrics and adults. Conclusion: We reinforce the necessity of continous epidomiologic surveillance to follow the dynamics of candidemia.
