Risk Factors and Prognosis of Hepatic cGVHD after Allogeneic Hematopoietic Stem Cell Transplantation / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the risk factors and prognosis of hepatic chronic GVHD after allogeneic hematopoietic stem cell transplantation (allo-HSCT).</p><p><b>METHODS</b>The clinical data of 147 patients undergoing allo-HSCT from January 2013 to December 2016 were analyzed, the correlation between recipient age and sex, disease state, matched degree of HLA, donor sex, stem cell sources, ATG in GVHD prophylaxis, liver dysfunction during conditioning period, pre-transplant HBsAg, prior aGVHD and hepatic cGVHD were studied, and the correlation between hepatic cGVHD and prognosis were analysed.</p><p><b>RESULTS</b>Thirty-two patients had hepatic cGVHD, cumulative incidence of 26.4%. In univariate analysis, pre-transplant HBsAgand liver dysfunction during conditioning period were not significantly related with hepatic cGVHD (P>0.05). In multivariate analysis, prior acute GVHD (HR=2.087, P=0.045) was the independent risk factor for hepatic cGVHD, ATG (HR=0.231, P=0.000) was significantly related with a lower incidence of hepatic cGVHD. In univariate analysis, patients with hepatic cGVHD had a lower 2 years relapse rate (P=0.038).</p><p><b>CONCLUSION</b>Prior acute GVHD is the independent risk factor for hepatic cGVHD, the ATG can significantly reduce the incidence of hepatic cGVHD. Hepatic cGVHD has been found to relate with a lower 2 years relapse rate.</p>
