Abstract |
Introduction: Gut colonization with antibiotic-resistant bacteria (ARB) is associated with a significantly decreased overall survival in adult patients undergoing allo-HCT because of an increased treatment-related mortality.
Objective: The objective of this multicenter study was the analysis of impact of gut colonization status and the use of antibiotics on development of gastro-intestinal (GI) graft-versus-host disease (GVHD) of allo-HCT in children.
Methods: All consecutive patients who underwent allo-HCT over a period of three years in all pediatric HCT centers in Poland were analyzed for the impact of gut colonization on GI GVHD, with respect to standard of care including prophylaxis of infections and supportive therapy.
Results: At the time of allo-HCT, 44.2% of pediatric patients were colonized by ARB. Decontamination therapy with antibiotics was applied in 78% of children. Gut decontamination prophylactic therapy with antibiotics decreased the risk of acute GI GVHD. The use of gentamicin contributed to decreased rate of GVHD, while the use of ciprofloxacin and colistin contributed to increased incidence of GVHD after allo-HCT in children. Sepsis with ARB and non-MFD transplant contributed significantly to worse survival, while neither colonization nor gut decontamination had an impact on overall survival.
Conclusions: Gut decontamination therapy contributed to lower incidence of acute GI GVHD in children undergoing allo-HCT, and the use of specific antibiotics might be responsible for this effect.
