JUSTIFICATION: Candiduria is increasingly frequent among patients admitted to intensive care units but its significance remains unclear. OBJECTIVES: Search for eventual correlation between quantitative candiduria and known risk factors for invasive candidiasis. STUDY DESIGN: Prospective. PATIENTS AND METHODS: A four-month study was conducted in 162 patients hospitalized in the intensive care unit for more than 72 hours. All patients underwent a weekly research of candiduria added to sampling from different body sites to determine the Pittet Candida colonization index. RESULTS: Candiduria has been proved in 56 cases (34%). It was superior or equal to 10(4) UFC/ml among 28 patients (50%). Candida tropicalis, Candida glabrata and Candida albicans has been isolated in 41, 22 and 20% respectively. All patients had at least one major and two minor risk factors for Candida infection. Six patients (10%) developed invasive candidiasis. The global mortality rate was at 52%. Pittet colonization index was significantly different between patients with candiduria and those with invasive candidiasis (p=0.01). There was a statistically significant correlation between candiduria superior or equal to 10(4) UFC/ml and Pittet colonization index superior or equal to 0.5 (p=0.01). CONCLUSION: Candiduria superior or equal to 10(4) UFC/ml associated with risk factors may predict invasive candidiasis in critically ill patients.
