Abstract

Two cases of non-familial haemophagocytic lymphohistiocytosis (HLH) are presented in which treatment with interferon alfa and gammaglobulin was associated with complete clinical remission. In one case, serological evidence of recent Epstein-Barr virus infection was found. Natural killer cell activity was within normal limits in both children, compatible with a secondary form of HLH. The combination of interferon alfa and intravenous gammaglobulin requires further evaluation in the treatment of non-familial HLH.
