title: [Comparison of therapeutic effect of different doses of ganciclovir for neonatal congenital cytomegalovirus infection].
abstract: OBJECTIVE
  Ganciclovir is a first-line drug for treatment of cytomegalovirus (CMV) infection. However, some ganciclovir treatment-related side-effects can be found. This study aimed to compare the efficacy and side effects of relatively low and high doses of ganciclovir in the treatment of neonatal congenital CMV infection.
  
  
  METHODS
  One hundred and sixty-seven neonates with congenital CMV infection were randomly assigned to high-dose (n=79) and low-dose ganciclovir groups (n=88). The high-dose ganciclovir group was injected with ganciclovir of 7.5 mg/kg in the inducement phase and of 10 mg/kg in the maintaining phase. The low-dose ganciclovir group was injected with ganciclovir of 5 mg/kg in the inducement and the maintaining phases. The efficacy and side effects were observed in the two groups.
  
  
  RESULTS
  After treatment the clinical symptoms and signs were obviously improved in both groups. CMV-IgM became negative in 93.8% of neonates in the high-dose ganciclovir group and 93.1% of neonates in the low-dose ganciclovir group (P>0.05). CMV-DNA became negative in 80.8% of neonates in the high-dose ganciclovir group and in 86.7% in the low-dose ganciclovir group (P>0.05). The low-dose ganciclovir group had lower incidence of side effects than the high-dose ganciclovir group: vomiting 2.3% vs 11.4%; anemia 8.0% vs 20.3%; reduction of neutrophilic granulocytes 5.7% vs 16.5%; increase in platelet count 8.0% vs 18.9% (P<0.05).
  
  
  CONCLUSIONS
  Low-dose ganciclovir has the same clinical efficacy to high-dose ganciclovir for treatment of neonatal congenital CMV infection, but fewer side effects occur in the low-dose group.
