The aim of this study was to determine the incidence and outcome of herpes zoster hospitalised children with cancer in Kota Baru. It was a retrospective review from January 1994 to December 1998. The diagnosis of herpes zoster was a clinical one. Herpes zoster was diagnosed in 10 of 188 (5%) children with malignancy. The most common malignancy was leukaemia. Nine children were treated with acyclovir. No child developed visceral dissemination and there were no deaths.
Primary varicella-zoster virus infection in children with haematological malignancy is a life threatening disease. In one year, there were 10 cases of varicella and 2 cases of zoster among these children as well as 5 mothers who were accompanying their children who developed varicella in the oncology ward. Two children died of fulminating disease despite aggressive antiviral and supportive treatment. Acyclovir can be used in treatment and prophylaxis in exposed susceptible children. Varicella -zoster immune globulin is not available in this country. Vaccination with live virus has been shown to be protective in immunocompromised children and needs consideration.
