Risk factors for nosocomial candiduria due to Candida glabrata and Candida albicans

Abstract

The aims of this study were to analyze the clinical characteristics and risk factors associated with catheter-associated candiduria due to Candida glabrata and due to Candida albicans and to compare patients with candiduria due to C. glabrata or C. albicans (cases) with controls. Controls were a randomly chosen sample of inpatients with Foley catheters for whom urine cultures were negative for Candida species. Univariate and multivariate analyses were performed. There were 40 cases of C. glabrata candiduria and 289 cases of C. albicans candiduria. Factors strongly associated with both C. albicans candiduria and C. glabrata candiduria were female gender (P <. 05) and being in the intensive care unit (P <. 01). Fluconazole use (adjusted odds ratio, 4.37; P <. 01) and quinolone use (adjusted odds ratio, 3.16; P <. 01) were specifically associated with C. glabrata candiduria but not with C. albicans candiduria. In conclusion, patients receiving fluconazole treatment are at risk of developing C. glabrata candiduria.
