Epidemiologic characteristics of adult candidemic patients in a secondary hospital in Kuwait: A retrospective study

Candida blood steam infection is a life-threatening disease that seems to be under estimated. Understanding epidemiology of such disease is crucial for improved diagnosis, optimized treatment, and better outcome. Through this retrospective study, we aimed to determine the incidence of candidemia in a secondary care hospital, and to describe the epidemiology and outcome of candidemia among adult patients. The incidence of candidemia for all age groups was 0.24, 0.16 and 0.15 cases/1000 patient-days in 2014, 2015 and 2016 respectively. Among adult patients, 82 cases were identified. The patients had the following clinical characteristics with varying proportions: old age, diabetes, antibiotic exposure, use of vascular catheter, abdominal surgery, ICU hospitalization, haemodialysis, and total parenteral nutrition. All-cause 30-day mortality was 54% and ICU hospitalization was a recognized risk factor for death. The leading causative agents were Candida albicans (32%), and Candida parapsilosis (32%), followed by Candida tropicalis (20%), Candida glabrata (13%) and one each by Candida dubliniensis, Candida famata, and Candida auris. Almost all tested isolates were susceptible to caspofungin and amphotericin B. With regard to fluconazole, C. glabrata showed variable susceptibility. Other species were susceptible except one isolate, each of C. parapsilosis and C. auris. The study highlights the growing importance of non-C. albicans Candida species in the etiology of candidemia. Emergence of C auris is a warning sign and needs to be closely monitored. (C) 2018 Elsevier Masson SAS. All rights reserved.
