Změny mikrobiálního osídlení trávicího traktu u pacientů po alogenní transplantaci hematopoetických buněk / Changes in microbial colonization of gastrointestinal tract in patients after allogeneic hematopoietic stem cell transplantation

Introduction: Physiological microflora is characterised by wide diversity. The microbial community is mostly composed of bacteria, but also includes fungi, archaea and viruses. Anaerobic commensal bacteria (Firmicutes and Bacteroidetes) dominate 90% of the colon. The composition and products of the gut microbiota have a significant effect on an individual's immune system, and their interactions may ultimately promote immune tolerance or inflammatory immune response. Blood cell transplantation (HSCT) and its associated standard procedures of conditioning, antibiotic exposure and dietary prophylaxis represent modification and disruption of the gut microbiota leading to the development of some serious post-transplant complications affecting the OS (overall survival) and TRM (treatment related mortality) of patients. Objectives: The aim of this work was to investigate the representation of individual bacterial strains in patients undergoing allogeneic HSCT, as well as the effect of transplantation on the composition and diversity of their gut microbiota. Methods: Stool samples were obtained from 52 patients who underwent an allogeneic hematopoietic cell transplant at the Institute of Hematology and Blood Transfusion in Prague. A cut-off date for the first sample was set for the start of...
