[Risk factors and outcome of invasive fungal infection in 79 patients received allogeneic hematopoietic cell transplantation].

Objective: To study the incidence, risk factors and outcome of invasive fungal infection(IFI) in the recipients with allogeneic hematopoietic cell transplantation(HSCT).

Methods: 79 cases received HSCT in our hospital from January 2005 to November 2014 with complete data were analyzed retrospectively according to the diagnostic criteria of IFI. the clinical features, risk factors and outcome of IFI were investigated and analysed.

Results: 17 cases of IFI were diagnosed, among them 13 cases were defined in clinic and 4 cases were possible. The median time of IFI occurence was 112 days(9-1931 d). The recurrence-free survival rate in non-infection and infection groups were 61.2% and 35.2% respectively. By single-factor analysis, the matching, II and IV degree of aGVHD were the risk factors of IFI, and the sex, protopathy, glucocorticoid used before infection were the risk factors of the death outcome. Multivariate analysis may indicated that the matching, II-IV degree of aGVHD and glucocorticoid used before infection were associated with IFI and outcome.

Conclusion: The patients received HSCT and having many risk factors are more likely predisposed to IFI. A greater dose of glucocorticoid used before infection is more likely to results in death, morever avoiding the risk factors may reduce the incidence of IFI, and the retrospecion of immunosupperssor dose used within 30 days before infection may improve prognosis.
