Epidemiology of nosocomial fungal infections in the National Center for Burns in Casablanca, Morocco.

Fungal infection is a leading cause of death in burns patients and incurs significant costs for burn units. Our aim was to determine epidemiology of these infections, and analyze risk factors in the burns intensive care unit of the National Center for Burns and Plastic Surgery at Ibn-Rochd University Hospital, Casablanca. It is a retrospective review of all patients admitted from 2011-2014 who developed cultures positive for fungal organisms. Criteria for nosocomial fungal infections were those of the Center for Disease Control in Atlanta (1988, revised 1992, 2004). Microbiological surveillance was carried out daily. Patient demographic data, % TBSA, type of infection, site(s), species and number of cultures, and risk factors for fungal infections were collected. Mean age of patients was 24.5 +/- 27.3 years; 63% were female. Mean % TBSA was 30.7 +/- 23.4%, and % FTSA was 21.7 +/- 20.1%. Injury due to flame was most common (82%), followed by scald (10%), contact (4%), electrical (3%) and chemical (1%). Incidence of nosocomial fungal infection was 10%. The fungal pathogen most frequently isolated was Candida albicans (65.7%), followed by other Candida species (18.6%). Aspergillus spp was present in 3.9% and was statistically associated with mortality (3.2%) and morbidity. In our study, risk factors for these infections were mostly degree of burn (mean TBSA = 30.7%) and prolonged broad-spectrum antibiotic therapy. These two factors were associated with a higher incidence of multiple positive cultures, and significantly increased mortality (21.6%). Amphotericin B and fluconazole were the most frequently used antifungal agents. Fungi are emerging as important nosocomial pathogens. The main clinical implications are thinking faster about fungi infections and being more careful with antibiotic prescriptions.
