Twenty-one HIV negative Japanese patients with chronic hepatitis C who had congenital bleeding disorders, 15 hemophilia A, 3 hemophilia B, 1 von Willebrand's disease, 1 afibrinogenemia and 1 thrombasthenia, were treated with 9 million units 3 times a week of natural interferon (IFN)-alpha for 6 months. They were followed, biochemically and virologically, for at least 18 months after therapy discontinuation to evaluate the long-term results. Liver biopsy, hepatitis C virus (HCV) genotyping and quantification of viral load by polymerase chain reaction (PCR) were performed to identify the predictors of a favorable response to IFN treatment. One male patient with hemophilia A dropped out because of general fatigue and was excluded from evaluation. Ten (50.0%) patients continued to be HCV RNA negative in serum together with normal ALT levels throughout the study. Subtype 1b and a high level of viremia significantly associated with an unfavorable outcome on the response to IFN although liver histology was not definitive for predicting the response. We concluded that a 6-month treatment with high doses of natural IFN-alpha was effective in inducing a long-term response without relapse of viremia in 50% of chronic hepatitis C patients with congenital bleeding disorders and that HCV subtype and pretreatment level of viremia were useful predictors of the response to IFN in treating such patients.

Mixed cryoglobulinemia is a systemic vasculitis with clinical manifestations ranging from the characteristic benign-appearing syndrome of palpable purpura, arthrologies, and fatigue to severe vasculitis involving vital organs. A strong association of the disease with hepatitis C virus infection and the demonstration of the specific concentration of the virus in the cryoglobulins have implicated hepatitis C virus in the etiopathogenesis of the disease. The increase in illicit intravenous drug use in the past 30 years seems to have raised the occurrence in the United States of this once uncommon disease and changed the demographics: there seem to be more male intravenous drug users in their forties with the disease than women without risk factors for hepatitis C virus infection in their fifties and sixties. Pathogenesis, therapy, and the hypothesis on the etiologic role of hepatitis C virus are reviewed, and the implications of recent studies and new concepts for treatment of this often benign-appearing but deceptive and potentially life-threatening disease are discussed.

Therapy with ribavirin for 6-12 months is associated with decreases in serum aminotransferases in some patients with chronic hepatitis C. We have assessed the practicality and safety of prolonged therapy with ribavirin. Six patients with chronic hepatitis C were given 1000-1200 mg of ribavirin daily for 24 months. Serum aminotransferases and hepatitis C virus (HCV) RNA levels were monitored during and after therapy. Liver biopsies were carried out before and at the end of treatment. With therapy, mean serum alanine aminotransferase (ALT) levels fell from 161 U/L to 45 U/L at 12 months and to 39 U/L at 24 months. HCV RNA levels did not change. Liver histology improved in five and was unchanged in one patient. When therapy was stopped, aminotransferases rose to pretreatment levels. Side effects included mild fatigue and headaches. Two patients developed gallstones during therapy, perhaps caused by the chronic haemolysis that occurred in all patients. In conclusion, prolonged therapy with ribavirin can result in sustained improvements in serum aminotransferases and hepatic histology in a proportion of patients with chronic hepatitis C. Ribavirin therapy does not cause decreases in viraemia and, therefore, probably must be continued indefinitely to provide lasting benefit. The advantages of such therapy must be weighed against possible long-term side-effects.

We studied the morbidity of chronic hepatitis C in patients referred to a tertiary care medical facility. The medical records of 500 consecutive cases of chronic hepatitis C were examined for the following: (1) source and time of exposure, (2) signs and symptoms of liver disease, (3) degree of alcohol intake, (4) liver biopsy findings, (5) extrahepatic disease manifestations, and (6) coexisting illnesses that could have an impact on morbidity. Morbidity and histologic findings were evaluated in relation to the duration of hepatitis C. The onset of infection could be determined in 376 patients (75%). A close relationship between the length of infection and disease features was not observed. Fatigue was common at all stages of infection. Whereas cirrhosis occurred more frequently in patients with disease of long duration, 15-24% of patients had signs of advanced liver disease (ascites, encephalopathy, thrombocytopenia) within six years of exposure. Overt extrahepatic manifestations of chronic hepatitis C occurred infrequently, and depression was reported in 24% of untreated patients. In conclusion, in patients referred to a tertiary care setting, chronic hepatitis C is often associated with significant morbidity.

Between 1971 and 1989 we have treated 19 patients with hepatitis-associated aplastic anemia by marrow transplantation from their HLA-identical siblings following conditioning with 200 mg/kg cyclophosphamide (Cy) administered over a period of 4 days. One patient failed to engraft by day 34 and was given a second transplantation. He died from infection 15 days after the second transplantation. Eighteen patients had sustained engraftment. Six patients developed acute graft-vs.-host disease (GVHD) and two of these patients died 2.8 and 3.3 months after transplantation. Fifteen patients are surviving 4 to 24 (median 13) years after transplantation, while one patient died in a car accident 17 years after successful transplantation. Six of the surviving patients developed chronic GVHD. Two of the patients with chronic GVHD had preceding acute GVHD and four did not. Five of the six patients with chronic GVHD received donor buffy coat cells in addition to the marrow inoculum to prevent graft rejection. Twelve of the 15 surviving patients have Karnofsky performance scores of 100%. One patient, living more than 4 years after transplantation, has a Karnofsky score of 40% because of persistent cognitive deficits following non-A, non-B hepatitis with hepatic coma. Two patients developed hepatitis C infection 12 and 18 years after transplantation, respectively. Except for mild fatigue and mildly elevated liver function tests, these patients are doing well with Karnofsky performance scores between 95 and 100%. One patient developed severe coronary artery disease 10 years after transplantation, decreasing his Karnofsky performance score to 80%. Serum samples before and after transplantation from 13 patients were tested for hepatitis B virus (HBV) DNA and hepatitis C virus (HCV) RNA by polymerase chain reaction (PCR). Only one patient tested positive for HCV RNA before transplantation. Seven of 15 sera were hepatitis C RNA-positive posttransplantation, but only one of these patients has developed active hepatitis C. All 13 patients were were negative for hepatitis B surface antigen and HBV DNA. Only one patient had IgM antibodies against hepatitis A virus (HAV) before transplantation, which suggested HAV infection. Hepatitis-associated aplastic anemia apparently was caused in most patients by a non-A, non-B, non-C agent. HLA-identical marrow transplantation for hepatitis-associated aplastic anemia with Cy as conditioning regimen is well-tolerated and has a long-term event-free survival in excess of 80%, not different from results of marrow transplantations for aplastic anemia of other etiologies.

Hepatitis C is a common cause of chronic liver disease that may progress to cirrhosis. We conducted a multicenter double-blind placebo-controlled trial of ribavirin 600 mg given orally twice daily for 36 weeks with follow-up off therapy for an additional 16 weeks. Fifty-nine patients with compensated chronic hepatitis C were entered. Efficacy was measured at the end of therapy and after follow-up by normalization of alanine aminotransferase (ALT), improvement in liver histology, reduction in hepatitis C virus (HCV) RNA level and improvement of symptoms. Among the ribavirin recipients, 12 of 29 (41.4%) had normal ALT values at 36 weeks compared with only 1 of 30 (3.3%) placebo recipients (P < .001). No patient maintained a normal ALT when therapy was stopped. No significant decrease in level of HCV RNA was observed during the study. Histological improvement among subjects who normalized ALT (-1.67 Knodell index) was significantly greater than that in other treated patients (+0.33 Knodell index; P < .05). Fatigue improved in 19.2% of ribavirin-treated subjects and in 8.3% of placebo recipients whereas no worsening of fatigue was reported by ribavirin recipients compared with 16.7% of controls. This difference in fatigue was significant at weeks 36 and 52 (P < .05; .02, respectively). Adverse events were generally comparable between treatment groups except for a reversible hemolytic anemia experienced by ribavirin recipients. Chest pain was noted in four patients on ribavirin. Ribavirin was well tolerated and improved aminotransferase values and reduced fatigue in patients with hepatitis C viral infection while treatment was being administered. Because this action was produced without change in viral level, the mechanism of action of this agent requires further investigation.

The treatment of two cases of hepatitis C using herbal medicine and nutritional supplements is presented. The selection of medicinals was based upon both biomedical findings and traditional Chinese medical diagnosis. The text describes the course of each patient's illness documented both subjectively and objectively using blood values and traditional Chinese medicine analysis as parameters. Explanation and/or citations are given for each medicinal used. Both patients improved during the course of treatment; subjective signs and symptoms (especially fatigue) as well as liver enzyme levels demonstrated improvement.

A cross-sectional study was conducted of persons notified with hepatitis C virus (HCV) infection on the NSW North Coast during 1993 and 1994. The personal impact of infection was investigated using a self-administered questionnaire. Many cases were currently well, however nearly half reported fatigue and other adverse physical/mental/social outcomes were noted. Tobacco use by subjects was high. People with HCV infection require continued support via appropriate screening, referral and treatment services; access to information; and countering community discrimination, stereotyping and concern about HCV.

We report a 75-year-old Japanese man infected with hepatitis C virus (HCV) who died of acute hepatic failure due to the hepatic infiltration of B-cell non-Hodgkin's lymphoma (NHL) cells. He suddenly developed jaundice, fatigue, fever, and hepatosplenomegaly during the course of chronic infection with HCV. Postmortem liver necropsy revealed extensive infiltration of lymphoma cells into the liver. Although the association between HCV infection and NHL has recently become a matter of concern, we believe this to be the first reported case of acute hepatic failure caused by hepatic involvement of non-Hodgkin's lymphoma in an HCV-infected patient.

We analysed data from a multicentre interferon (IFN) treatment trial to evaluate symptoms in patients with chronic hepatitis C and to identify factors that might predict development of debilitating IFN side-effects. Two hundred and twenty-two patients (120 US, 102 French) received 3 or 5 million units (MU) of IFN-alpha three times weekly (t.i.w.) for 3 months. Those who had detectable hepatitis C virus (HCV) RNA, as detected by the branched DNA signal amplification (bDNA) assay, at 3 months were intensified to daily therapy, while patients who were bDNA negative continued t.i.w. dosing for the subsequent 3 months of treatment. Symptoms were assessed at baseline, and adverse effects were evaluated at 6 months of therapy. Prior to treatment, the most common symptom that interfered with daily functioning was fatigue, occurring in 25% of patients. The frequency of debilitating fatigue, myalgia, arthralgia, headache, the presence of dry eyes and dry mouth, and use of antidepressant medication increased significantly from baseline to 6 months of IFN therapy (all P < 0.01). In multivariate analysis, the development of a debilitating side-effect at 6 months of treatment was associated with the presence of that symptom prior to therapy in all cases. Symptoms and adverse effects varied by gender and country. Compared with patients maintained on t.i.w. dosing, those who were dose intensified to daily IFN reported more debilitating fatigue, malaise, myalgia, arthralgia, fever, nausea, and headache, and the presence of dry mouth (all P < 0.05). In conclusion, patient characteristics, including pretreatment symptoms, gender and nationality, as well as daily IFN dosing are associated with the development of debilitating adverse effects on IFN therapy.
