Abstract:OBJECTIVE: To study the significance of plasma D-dimer and von Willebrand factor (vWF) and the therapeutic effect of compound glycyrrhizin in children with cytomegalovirus (CMV) hepatitis. METHODS: Twenty healthy children, 16 asymptomatic cases with CMV infection and 52 cases of CMV hepatitis (21 cholestatic and 31 non-cholestatic) were enrolled. The 52 children with CMV hepatitis were randomly administered with conventional treatment alone or conventional treatment plus compound glycyrrhizin treatment. Plasma D-dimer and vWF levels were measured before and after treatment. RESULTS: Plasma D-dimer and vWF levels in the CMV hepatitis group were markedly higher than those in the healthy control and asymptomatic CMV infection groups (P<0.01). The cholestatic hepatitis group had more increased plasma D-dimer and vWF levels compared with the non-cholestatic hepatitis group (P<0.01). Plasma D-dimer and vWF levels in the CMV hepatitis group were markedly reduced after conventional or compound glycyrrhizin treatment (P<0.01). Compound glycyrrhizin treatment decreased more significantly plasma D-dimer and vWF levels compared with the conventional treatment in children with CMV hepatitis (P<0.01). CONCLUSIONS: The detection of plasma D-dimer and vWF is useful in the early assessment of liver damage in children with CMV hepatitis. Compound glycyrrhizin can decrease obviously plasma D-dimer and vWF levels and might thus provide protective effects against liver damage.［Chin J Contemp Pediatr, 2010, 12 (4):272-274］
