Epidemiology of invasive fungal diseases in children with solid tumours undergoing autologous haematopoietic stem cell transplantation: a 10‐year experience in a tertiary Italian centre
The objective of the study was to determine the incidence of invasive fungal disease (IFD) in children undergoing autologous haematopoietic stem cell transplantation (auHSCT) for solid tumours (ST). Retrospective study on auHSCT was performed in children with ST (January 2006‐December 2015). Data on the number of patient‐days at risk (pdr) during the first 30 and 90 days after auHSCT and cases of proven/probable IFDs were collected. Infection rate (IR, episodes/1000 pdr) and proportions and cumulative risk (CR) of IFD were evaluated. In 186 patients, 270 auHSCT were performed, for a total of 8327 pdr during the first 30 days and 24 366 up to day 90. Median age was 5 years (interquartile range 2;8), 63% were male. At day 30, seven procedures were complicated by IFD, with an IR of 0.84 (95% CI 0.66‐1.02) and aCR of 2.6% (95% CI 1.4‐5.4) at 18 days after HSCT. Within day 90, two further IFDs were detected with an IR of 0.37 (95% CI −0.49 to 1.23) and a CR of 3.3% (95% CI 1.7‐6.3) at day 69. Children undergoing auHSCT for ST have a low incidence of IFDs in the first 90 days after the procedure.
