title: Candiduria in catheterized intensive care unit patients: emerging microbiological trends.
abstract: OBJECTIVE
  Urinary tract infection (UTI) as a result of Candida spp. is becoming increasingly common in hospitalized setting. Clinicians face dilemma in differentiating colonization from true infection and whether to treat candiduria or not. The objective of the present study was to look into the significance of candiduria in catheterized patients admitted in the ICUs and perform microbiological characterization of yeasts to guide treatment protocols.
  
  
  METHODS
  One hundred consecutive isolates of Candida spp. from the urine sample of 70 catheterized patients admitted in the ICU were collected and stocked for further characterization. A proforma was maintained containing demographic and clinical details. Blood cultures were obtained from all these 70 patients and processed. Species identification of yeasts was done on VITEK.
  
  
  RESULTS
  Candiduria was more common at extremes of age. The mean duration of catheter days was 11.1 ± 6 days. Other associated risk factors such as diabetes mellitus and antibiotic usage were seen in 38% and 100% of our study group. Concomitant candidemia was seen in 4.3% of cases. Non-albicans Candida spp. (71.4%) emerged as the predominant pathogen causing nosocomial UTI.
  
  
  CONCLUSIONS
  The present study reiterates the presence of candiduria in catheterized patients, especially in the presence of diabetes and antibiotic usage. Non-albicans Candida spp. are replacing Candida albicans as the predominant pathogen for nosocomial UTI. Hence, we believe that surveillance for nosocomial candiduria should be carried out in hospitalized patients.
