Transfusion Transmitted Virus Hepatitis in Neonates and Curative Effects of Genciclovir / 实用儿科临床杂志

ABSTRACT

Objective To investigate the pathogenicity of transfusion transmitted virus (TTV) infection and assess the effect of genciclovir on TTV.Methods Serum TTV-DNA from 968 neonates was detected by a nested polymerase chain reaction technique and electropherosis. Alanine aminotrans ferase (ALT) and direct bilirubin (DB) were assayed in neonates with positive TTV-DNA.Genciclovir[10 mg/(kg?d)]was used to treat neonates with TTV-induced hepatitis.Results Among 968 neonates, 38 had positive TTV-DNA (4.0%). All neonates with positive TTV-DNA had normal serum levels of ALT and DB [(24.8?12.0) U/L and (17.6?6.8) ?mo l/L] 3 days after birth;But an elevated ALT and DB level [(95.5?16.4) U/L and (58.2?10.4) ?mol/L] occurred in 15 of them 2 weeks after birth,and were diagnosed as TTV-induced hepatitis.These patients had hypersomnia,jaundice and anorexia. Serum ALT and DB levels recovered to normal range one week after genciclovir therapy in 11 patients,so did the other 4 patients after 2 weeks therapy with genciclovir. Serum TTV-DNAs in all patients became negative 2 weeks after genciclovir therapy.Conclusion TTV infection exists in the neonates, and may be one of important causes of neonatal hepatitis.genciclovir might have a good anti-TTV effect.
