Infections after hematopoietic cell transplantation are not a burden for mortality at a limited-resource center in a developing country.

ABSTRACT

BACKGROUND: Hematopoietic cell transplantation (HCT) outcomes, including infectious complications, change between centers and countries. Thus, the aim of this study was to report the incidence of infections and isolated pathogens among recipients of HCT and the association with mortality at a tertiary referral center in Mexico. METHODS: Two hundred and eighty-two patients undergoing autologous or allogeneic HCT between January 2005 and December 2018 at the National Institute of Medical Sciences and Nutricion Salvador Zubiran were included. RESULTS: In autologous HCT (n = 176), within the preengraftment and the early postengraftment, 130 (74%) and 31 (18%) recipients presented infections, respectively. Within the preengraftment, the early postengraftment, and the late postengraftment, 81 (76%), 34 (33%), and 58 (60%) allogeneic HCT recipients presented infections, respectively. Non-relapse mortality (NRM) as a result of infections occurred in 1 (0.6%) and 5 (5%) autologous and allogeneic HCT recipients, respectively. CONCLUSIONS: Our results demonstrated that despite our limited resources, infections were not a significant burden for NRM among HCT recipients. More importantly, the isolation rates were higher than international studies, which could be explained by the existence of a specialized infectious diseases department and laboratory, which we consider key elements for the establishment of an HCT program worldwide.
