Abstract
Endogenous danger signals are increasingly recognized in the pathogenesis of graftversushost disease GVHD Uric acid UA is a known danger signal and is released from injured cells during conditioning for allogeneic hematopoietic stem cell transplantation HSCT but its role in GVHD is unclear Here we retrospectively analyze 228 consecutive patients with malignant diseases undergoing HSCT from 10/10HLAmatched donors Low UA levels at the time of HSCT day 0 were significantly associated with acute GVHD grades II–IV in univariate HR 0836 p = 00072 and multivariate analyses HR 0815 p = 00047 There was no significant association between UA levels and overall survival nonrelapse mortality and relapse This is the first report demonstrating a negative association between UA levels and acute GVHD Due to the easy assessment and established pharmaceutical modification of UA our findings are potentially clinically relevant Confirmation in independent cohorts and further investigations into underlying mechanisms such as reduced antioxidative capacity in hypouricemia are warranted
