title: [Epidemic focus of non-A, non-B viral hepatitis in a plasmapheresis unit].
abstract: Non-A, non-B hepatitis has been diagnosed in 12 blood donors in a plasmapheresis unit. The course of the disease has been symptomatic, accompanied by jaundice, fatigue, and nausea in 8 cases, and subclinical in the remaining 4 patients. Nine patients were followed-up to 2 years and only 2 patients liver biochemical tests were normalized permanently. The biopsies performed, a year after the acute phase of hepatitis period revealed chronic active disease in patients, chronic persistent hepatitis in 2 patients, acute hepatitis in one, and normal liver in one patient. Repeated liver biopsies, performed one year later, have basically shown similar lesions except one patient in whom chronic active hepatitis progressed to incipient liver cirrhosis. No symptoms of the disease have been usually noted in patients with chronic form of the disease, and liver function tests have occasionally been normal.
