microbiota and hematological diseases

The microbiota is directly involved in the host metabolic process, as well as in immune response modulation and recruitment of different cells typology in the inflammatory site. human microbiota modification (dysbiosis) is a condition which could be correlated with various pathologies. the short-chain fatty acids produced by the metabolic process have an important role as immune mediators. in hematology field, dysbiosis can represent a predisposing condition for triggering and/or conditioning both non-neoplastic (iron deficiency anemia, thrombosis, thrombocytosis or thrombocytopenia) and neoplastic disorders (lymphomas, leukemias, myeloma). dysbiosis may also interfere on therapy efficacy (iron supplementation, chemotherapy, immunotherapy, and hematopoietic stem cell transplantation), impacting on patient's outcome.
