[Excessive hyperferritinemia as an indication of a reactive hemophagocytosis syndrome].

History and Admission Findings: A 17-year-old girl with a history of a polyarthritis of unknown etiology was admitted because of acute fever and general weakness. There were palpable cervical lymph nodes and her body temperature was 39.5 degrees C.
Investigations: GOT was raised to 282 U/1, GPT to 266 U/l lactate dehydrogenase to 1275 U/I and bilirubin to 0.6 mg/dl. The Quick value was 67%, albumin 28 mg/dl. White cell count was decreased to 1700/microl, with 43% granulocytes, 39% lymphocytes, 17% monocytes. Platelet count was 64,000/microl. Ultrasound revealed splenomegaly. Ferritin was markedly raised to 11,860 ng/ml (normal up to 150 ng/ml). An epstein-barr-virus infection was found.
Therapy and Clinical Course: Suspecting a reactive hemophagocytosis syndrome, she was treated with prednisolone (2 mg/kg). The diagnosis was confirmed by a bone marrow aspirate. The patient's condition and laboratory values improved rapidly.
Conclusion: Markedly increased ferritin levels in a clinically septic patient with an underlying rheumatic disease indicates a hemophagocytotic syndrome. High dosage steroid should be started before there is biopsy confirmation of the disease.
