Hepatitis A infection related haemophagocytic syndrome: a case report and systematic review.

Haemophagocytic lymphohistiocytosis (HLH) is a clinical syndrome of excessive inflammation and tissue destruction owing to abnormal immune activation. We report an unusual case of haemophagocytosis associated with hepatitis A virus (HAV) infection in a 21-year-old man. This was further complicated by haemolysis secondary to G-6-PD deficiency and fungal sepsis. Our patient was treated successfully with intravenous immunoglobulin (IVIg) and supportive care. A systematic review of all reported cases of HAV associated haemophagocytosis is presented.
