Epidemiology of paediatric invasive fungal infections and a case-control study of risk factors in acute leukaemia or post stem cell transplant.
Patients aged 0-18 years with confirmed or possible invasive fungal infection were identified by medical record and database searches. Cases with an underlying diagnosis of acute leukaemia or following stem cell transplantation were included in a case control study. Controls included all other children with acute leukaemia or stem cell transplant in the corresponding time period. Variables collected included demographics, underlying disease risk and status, organ impairment, admission to intensive care unit, fungal infection details and certain transplant variables. Risk factors for development of invasive fungal infection were examined using logistic regression. There were 106 cases of invasive fungal infection during the study. The incidence of invasive fungal infection was 21% in acute lymphoblastic leukaemia, 15% in acute myeloid leukaemia and 25% following stem cell transplantation. Sixty per cent were neutropenic at diagnosis and 39% had concomitant bacteremia. High risk acute lymphoblastic leukaemia, relapsed disease, intensive care admission and graft-versus-host disease were significantly associated with development of invasive fungal infection on multivariate analysis. These associations provide new information on paediatric invasive fungal infections and warrant further study; caution should be encouraged when extrapolating from adult studies.
