Non-familial haemophagocytic lymphohistiocytosis in children.
Haemophagocytic Lymphohistiocytosis (HLH) is a rare clinical illness with a high mortality. There are reported effective treatment and a favourable outcome if diagnosed early. Five cases of childhood non-familial HLH seen over a 3 year period in our hospital are presented. The diagnosis was not suspected in the referring hospitals even after a bone marrow biopsy examination in two cases. Delay in referral was between 2 weeks to 2 months. A viral trigger was detected in only two cases. There were two deaths. Cause of death in both cases were cytomegalovirus pneumonitis and disseminated intravascular coagulopathy. Respond to treatment was better if started earlier. One case spontaneously resolved. Earlier diagnosis will lead to prompt treatment and a better outcome.
