A 53-year-old man was admitted to our hospital for close examination of his liver. Serum hepatitis C virus (HCV) RNA and anti-liver/kidney microsome (LKM) 1 were positive. Benign monoclonal gammopathy and type I cryoglobulinemia (both of IgG lambda class) which are rarely seen in association with chronic hepatitis C, were found to be present. Interferon therapy was given, resulting in the disappearance of both HCV-RNA and type I cryoglobulin in the blood. We propose a hypothesis that the primary cause of anti-LKM-1-positive chronic hepatitis C is HCV infection which triggers secondary autoimmune phenomena presenting anti-LKM-1 and cryoglobulinemia.

D007372 Interferons Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions. Interferon

D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D003449 Cryoglobulinemia A condition characterized by the presence of abnormal quantities of CRYOGLOBULINS in the blood. Upon cold exposure, these abnormal proteins precipitate into the microvasculature leading to restricted blood flow in the exposed areas. Cryoglobulinemias
D006526 Hepatitis C INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.
