Abstract:
Objective: To evaluate the epidemiology of candidiasis and the antifungal susceptibility profile of Candida species isolated from the intensive care unit (ICU) patients. Methods: The study used a qualitative descriptive design. Relevant samples depending on organ system involvement from 100 ICU patients were collected and processed. Identification and speciation of the isolates was conducted by the biochemical tests. Antifungal susceptibility testing was carried out as per CLSI-M27-A3 document. Results: Ninety Candida isolates were isolated from the different clinical samples: urine (43.3%), tracheal aspirate (31.1%), urinary catheter (12.2%), endotracheal tube (7.8%), abdominal drains (3.3%), sputum (2.2%). The incidence of candidiasis caused by non-albicans Candida (NAC) species (63.3%) was higher than Candida albicans (36.7%). The various NAC species were isolated as: Candida tropicalis (41.1%), Candida glabrata (10%), Candida parapsilosis (6.7%), Candida krusei (3.3%) and Candida kefyr (2.2%). The overall isolation rate of Candida species from samples was 53.3%. Antifungal susceptibility indicated that 37.8% and 7.8% of the Candida isolates were resistant to fluconazole and amphotericin B, respectively. Conclusions: Predominance of NAC species in ICU patients along with the increasing resistance being recorded to fluconazole which has a major bearing on the morbidity and management of these patients and needs to be further worked upon.
