Enterovirus-associated haemophagocytic syndrome in a neonate.
A 3-d-old neonate presented with fever, hepatosplenomegaly, coagulopathy, thrombopenia and anaemia. Secondary haemophagocytic lymphohistiocytosis was suspected, as persistent cytopenias were associated with hypofibrinogenaemia, haemophagocytosis in bone marrow and decreased NK cell. There was no positive family lymphohistiocytosis history or parental consanguinity. Bacterial investigation proved negative. The diagnosis of enterovirus maternofoetal infection was carried out. The infant's condition improved with symptomatic therapy from day 7. Follow up at 1 y was normal without relapse. This is the first report of a neonatal enteroviral infection that was responsible for excessive macrophage activation.
