CANDIDURIA IN IMMUNOCOMPROMISED INDIVIDUALS IN A TERTIARY CARE CENTER IN NORTHERN INDIA
Abstract
Fungal infections of the urinary tract, caused by Candida species, are becoming prevalent worldwide. The aim of our study was to determine the prevalence of candiduria in immunocompromised patients in our hospital. During a period of 1 year, a total of 418 urine samples were collected and transported to the Department of Microbiology. After direct microscopic examination, the samples were inoculated onto Sabaraud’s Dextrose agar with antibiotics. The Candida albicans and non-albicans were identified by colony morphology, Germ tube test, and Chlamydospore formation test on Corn Meal agar. The antifungal sensitivity testing was done by the Disc diffusion method. Out of 418 samples {174(41.62%) males and 244 (58.37%) females} Candida species has been isolated from 78 (18.66%) cases. Out of the 78 (100 %) isolates, 47 (60.25%) were Candida albicans and 31 (39.74%) were non-albicans species. The age ranged from sixteen months to 86 years. Various risk factors observed among the patients were long duration of hospitalization, catheter use, antimicrobial therapy/chemotherapy, diabetes mellitus, HIV, etc. Amphotericin B and Itraconazole were the most sensitive antifungal agents. However, more resistance was seen in the case of non-albicans Candida species against the same antibiotics. In conclusion, candiduria is relatively common in immunocompromised patients both by Candida albicans as well as non-albicans species. In addition, there is a strong correlation between the incidence of candiduria in immunocompromised patients and broad-factors impairing the immunity of patients. There is a rise in resistance against the antifungal agents for both Candida albicans and non-albicans species.
