[Risk factors associated with multiple-species candidemia]

Abstract

The incidence of fungemia has increased over the past decade. Multiple-species candidemia (MSC) has been infrequently reported. From 1998 to 2004, of 155 patients with diagnosis of candidemia at the Hospital de Clinicas (University of Buenos Aires), seven cases of MSC were identified (6 adults and 1 newborn) and compared with 21 cases of similar age and sex with monomicrobial candidemia. There were no differences in clinical data and outcome, except for the mediana duration of hospital stay (39 days for patients with MSC vs. 18 days for patients with monomicrobial candidemia, the mean time of central venous catheter permanence previous to candidemia (32 days for patients with MSC vs. 12 days for patients with monomicrobial candidemia and the duration of candidemia (5 days for MSC and 1 day for monomicrobial candidemia. In conclusion, although MSC episodes are less common than those caused by monomicrobial candidemia, modifiable risk factors such as duration of hospitalization and central venous catheter permanence account for the development of MSC.
