title: [Parvovirus B 19 associated hemophagocytic syndrome in a patient with hereditary sperocytosis].
abstract: Infections with parvovirus B 19 can cause aplastic crises with a rapid decline of hemoglobin levels in patients with hereditary spherocytosis. Usually, the symptoms and signs of the actual infection are mild. We here report on an eight year old girl with hereditary spherocytosis who was admitted to hospital with high temperature, headache, impaired consciousness and a profound anemia (Hb 2.9 mmol/l). Since she also developed low leukocyte and platelet counts a hematological malignancy was suspected. The bone marrow aspirate showed only 1 % erythroblasts and macrophages with active hemophagocytosis. The serum ferritin was 1381,4 ng/ml. Both, serology and PCR revealed an active infection with parvovirus B 19. Coagulation analysis suggested a low degree of disseminated intravasal coagulation (low fibrinogen, high D-dimers). We diagnosed a parvovirus B 19 associated hemophagocytic syndrome. With only symptomatic treatment the patient's condition and laboratory findings improved during the course of a few days. In accordance with other reported cases, the prognosis of parvovirus B 19 associated hemophagocytic syndrome seems to be better than in hemophagocytic syndrome of other origin.
