Abstrakt: Background: Hematopoietic stem cell transplantation (HSCT) is an important therapeutic strategy for several hematologic diseases. In the absence of a matched related donor, allogeneic HSCT has been associated with increased risk of infectious complications. Here, we present the clinical and epidemiological characteristics of early infectious complications in children undergoing HSCT from Southern Brazil.
Methods: This is a retrospective unicentric cohort study of infections in all children receiving their first HSCT during the period between 2010 and 2017.
Results: Data from 292 patients were analyzed; bone marrow failures (52.7%) comprised most of the baseline diagnosis. Bone marrow (BM) was the stem cell source in 254 (87%), followed by cord blood (CB) in 34 (11.6%) children. The use of alternative donors (77.8%) and presence of acute graft-vs-host disease (GVHD) (23.6%) were associated with an increased risk of viral and fungal infection. Bacterial infection was observed in 79 patients (27%); 220 patients (75.3%) were diagnosed with viral infection, and 35 patients (12%) developed fungal infection. The presence of fungal disease together with the presence of multiple infections during follow-up was associated with an increased risk of death (P < .001).
Conclusions: The clinical profile of HSCT-related infections in this cohort suggests that prognosis in allogeneic HSCT is influenced by the source of stem cells (CB having worse prognosis), presence of acute GVHD and complications arising from fungal infections. The appropriate management of these factors has the potential to improve the overall prognosis rates in pediatric allogeneic HSCT recipients.
