Kurzbeschreibung/Zielsetzung
In a 59-year-old patient presenting in October 1981 with pancytopenia, hairy cell leukemia was diagnosed. Splenectomy, followed by treatments with oncovin, lithium, and prednisone were essentially without effect. Up to July 1984 the patient had been regularly transfused with a total of 62 unit. In June 1984 he acquired a transfusion associated hepatitis C which followed a chronic course and resulted in biopsy proven cirrhosis in 1989. The patient became independent of transfusions in July 1984. Repeated blood counts have shown a complete hematologic remission which has now lasted nearly 6 years, whereas focal leukemic infiltrates have persisted in the bone marrow. The patient has tolerated 20 courses of erythropheresis performed because of biopsy proven severe hepatic siderosis without a fall in hemoglobin. It is suggested that the spontaneous long-lasting hematologic remission of hairy cell leukemia is due to endogenous interferon produced in the course of chronic hepatitis C. Low serum levels of interferon-alpha and -gamma were detected.
