Objective: Candida could become the second most frequent cause of nosocomial urinary tract infection. Although Candida albicans is the most important species, others have arisen as emerging pathogens. The aim of this study was to analyze the presence of candiduria in inpatients.
Methods: We performed a retrospective study of Candida isolates from adult inpatient urocultures over five years, gathering and tabulating data on: the species; susceptibility to fluconazole, amphotericin B, and voriconazole (Vitek2, BioMerieux); presence of catheter; hospital department of origin; and patient age and sex.
Results: We detected 289 yeast episodes, observing an annual increase: 134 (46.4%) were non-C. albicans yeasts, with 57 (19.7%) being Candida glabrata, 37 (12.8%) Candida tropicalis, 25 (8.6%) Candida parapsilosis, and 10 (3.5%) Candida lusitaniae. Most isolates derived from catheterized (240, 83.0%) and Internal Medicine Department (118, 40.8%) patients, observing an annual increase; 152 (52.6%) isolates were from males, and the mean age was >65 years. Susceptibility to antifungals was >85%.
Conclusions: Inpatient urocultures should include data on the presence of Candida, which is more prevalent in Internal Medicine Department inpatients, in those with urinary catheter, and in over 65-year-olds. Almost half of the isolates were non-C. albicans yeasts, and we recommend complete identification of the species involved.
