불현성 감염 엄마로부터 감염된 신생아 수두 1례

A Case of Neonatal Chickenpox by an Asymptomatic Infected Mother

신생아 수두는 모체가 감염된 시기에 따라 그 증상과 예후가 달리 나타날 수 있으며, 출생 후 감염된 경우는 태반을 통해 모체로부터 태아에게 항체가 전달되지 못하기 때문에 합병증의 발생 가능성이 높고, 예후가 좋지 않아 적절한 치료와 추적관찰이 필요하다. 저자는 합병증의 동반없이 acyclovir를 사용하여 치료한 불현성 감염 엄마로부터 감염된 신생아 수두 1례를 경험하였기에 보고하는 바이다.

Chickenpox is a common childhood infection that generally resolves without complications. But maternal chickenpox near term, or soon after delivery, can cause severe or fatal illness in the newborn. The severity of neonatal chickenpox is closely related to the time of maternal infection and the fatality is reported up to 30%. Although chickenpox is thought to be a mild disease, complications are frequent in neonates and immunocompromised children. The diagnosis of neonatal chickenpox is usually based on the typical clinical feature, the characteristic point in time and the maternal history of chickenpox. Serologic methods have been widely used to confirm clinical diagnosis. To prevent severe neonatal chickenpox, passive immunization is indicated. If varicella occurs, acyclovir treatment has to be done promptly. But the use of acyclovir in symptomatic healthy infant is controversial. We report a case of neonatal chickenpox that was infected by an asymptomatic infected mother and rapid improvement of varicella skin lesions without complications after intravenous acyclovir administration.
