Core Tip

Core Tip: Graft-vs-host disease (GVHD) is the most unfavorable complication of hematopoietic stem cell transplantation (HSCT). Minimizing acute GVHD and inducing its chronic form is necessary to achieve good clinical outcomes in HSCT. GVHD consists of inflammation induced by the conditioning regimen, the alloimmune response of the T lymphocytes, and organ damage due to the graft-vs-host reaction. Biological factors have been comprehensively analyzed to identify novel combinations of biomarkers that predict acute GVHD severity and prognosis more efficiently. Currently, there are no useful biomarkers that can predict the severity and prognosis of chronic GVHD or serve a practical clinical use.
