Abstract
The use of direct-acting antivirals (DAA) for the hepatitis C virus (HCV) has yielded a significant improvement in the treatment of autoimmune hepatitis (AIH) associated with HCV infection. Interferon was the cornerstone of HCV therapy before the introduction of these agents into the clinical practice. Herein, we report the case of an HCV-infected patient who developed an interferon-induced AIH and since then, has received immunosuppressive therapy. Administration of DAA resulted in a sustained virologic response (SVR) and clinical AIH remission which allowed a discontinuation of immunosuppressive treatment.

Abstract
We present a case where a renal transplant recipient contracted chronic hepatitis C virus (HCV) infection post-transplantation. The disease progressed and deteriorated leading to fibrosing cholestatic hepatitis that mandated treatment. Treatment with pegylated interferon α-2a and ribavirin was successful in salvaging the liver and eradicating the virus but as a consequence lead to treatment-resistant acute rejection and loss of the renal allograft.

Abstract
The diagnosis of AIH depends on the finding of several suggestive features together with careful exclusion of liver diseases of other etiologies. Wherever possible, the diagnosis should be confirmed histologically by an experienced hepatopathologist. Seronegativity for the conventional autoantibodies at presentation does not exclude a diagnosis of AIH. It is important to test for anti-LKM1 antibodies to avoid missing a diagnosis of type 2 AIH, with potentially serious consequences. Although the syndrome is associated with characteristic biochemical abnormalities, and biochemical parameters are commonly used for monitoring response to therapy, it should be borne in mind that neither these nor autoantibody titers are completely reliable indices of disease activity. Although the various systems that have been promulgated for classification of the disease may identify different groups of patients on pathogenetic or clinical criteria and are useful for research purposes, none is yet sufficiently exclusive in terms of defining prognosis or planning treatment strategies to be applicable to the individual patient seen in the clinic. Clinical management should therefore continue to be individually tailored.

Abstract
Hepatitis C virus infects 20-40% of the end-stage renal disease population, and has been associated with essential mixed cryoglobulinemia and several forms of immune-complex glomerulonephritis. Overall, treatment with interferon alpha has been disappointing, although certain situations may benefit from dosing regimens that differ in the amount of drug and duration of treatment from the conventional interferon doses currently recommended for non-renal patients.

Abstract
BACKGROUND Interferon (IFN) is standard therapy for chronic viral hepatitis in children. The aim of this study was to evaluate the side effects of alpha-interferon (IFN) in 94 consecutive children (58 males; age range, 3 to 14 years) affected by chronic viral hepatitis treated with different schedules ranging from 3 to 10 MU and from 3 to 12 months, and the impact of this therapy on health-related quality of life. METHODS Side effects were evaluated with clinical and laboratory examinations and were recorded on a diary card. The health-related quality of life was evaluated with a modified version of the Sickness Impact Profile. RESULTS All patients experienced at least one adverse reaction to IFN treatment; 80% had more than five side effects. There were no life-threatening reactions. Three children experienced severe reactions (febrile seizure, severe hypertransaminasemia and relapsing episodes of epistaxis, respectively) that required permanent IFN withdrawal. Another child had a febrile seizure requiring temporary IFN withdrawal. In seven children the neutrophil count fell below 1000/mm3 and promptly increased when IFN was temporarily discontinued. The remaining children had mild or moderate clinical and/or laboratory adverse reactions. Age, sex, viral etiology of chronic hepatitis and response to therapy were not significantly associated with the appearance of side effects. The pre-IFN health-related quality of life was good in all children; it deteriorated significantly during IFN therapy and returned to basal standards within 3 months after IFN withdrawal. No patient required suspension of IFN therapy because of worsening of health-related quality of life. CONCLUSION Children have a low risk of developing severe IFN-induced side effects. Adverse reactions and worsening of health-related quality of life were tolerable and did not seem to be a limiting factor for IFN therapy in young candidates.

Abstract
AbstractMolecular biology is making a tremendous impact on the diagnosis and treatment of liver diseases. Methods such as the polymerase chain reaction are changing the way physicians diagnose and monitor patients with viral hepatitis. Assays based on recombinant protein antigens allow for detection of specific autoantibodies in diseases such as primary biliary cirrhosis. The diagnosis of inherited metabolic diseases, such as hemochromatosis and Wilson disease, is being revolutionized by discovery of the defective genes involved and the development of methods to rapidly sequence DNA and identify mutations. Treatments and preventive measures are now possible with use of drugs and vaccines produced by recombinant DNA technology. Gene therapy and nucleic acid-based therapeutics are also realistic future treatment options for individuals with liver diseases.

Abstract
IFN-alpha has emerged as a promising treatment of chronic viral hepatitis. Although therapeutic response to IFN is far from universal, efficacy has been demonstrated; and studies combining IFN-alpha with other agents, as well as trials with new preparations of IFN-alpha, are under way. Children do not represent a large part of the identified population with chronic viral hepatitis. Yet children, by simple virtue of age, are more recently infected. In addition, longer life expectancies can be expected to be associated with greater morbidity from chronic viral hepatitis. Children seem to tolerate therapy with IFN-alpha well. Treatment of children with chronic viral hepatitis should be strongly considered, with protocols designed to ascertain specific pediatric safety and efficacy.

Abstract
Screening for antibodies to hepatitis C virus (HCV) has substantially reduced the risk of HCV infection from transfusion of blood and blood products. Nevertheless, new infections may continue to occur. These infections may be caused by donor infections that escape detection or by insufficient decontamination of blood products during preparation. Frequently, HCV infection becomes chronic, is clinically silent, and can be associated with extrahepatic illnesses and liver cancer. A recent outbreak of HCV infection in patients who received intravenous immunoglobulin has permitted study of this infection in immunocompromised hosts. Some evidence indicates that this infection is more virulent in these patients, and our experience at Children's Hospital, Boston, Massachusetts, substantiates this finding. In this article, epidemiology and modes of transmission of HCV, pathogenesis of HCV infections, differential diagnosis, and clinical features of HCV infection in both children and adults are discussed. Particular attention is given to the serologic findings seen in the spectrum of diseases associated with chronic HCV infection. The mechanisms of action of interferon alfa treatment of HCV infections are discussed. However, results of interferon alfa treatment of patients with HCV infection at Children's Hospital are preliminary.

Abstract
Serial serum samples from 16 Italian patients presenting with acute hepatitis C virus (HCV) infections (which progressed to chronic hepatitis in six) were screened for the non-organ-specific autoantibodies most frequently associated with autoimmune hepatitis (AIH), as well as for antibodies against the hepatic asialoglycoprotein receptor (ASGP-R) and against the GOR peptide. One patient had low titres (1:10-1:80) of liver-kidney microsomal (LKM-1) antibodies during the recovery phase and three others had transient low titres of anti-smooth muscle (IgM class, 1:10) or anti-ASGP-R (1:150-1:300). Anti-GOR was detected in 43 (65%) of 66 sera from 13 of these patients. There was no correlation between any of these findings and progression to chronicity. By comparison, 18 patients with AIH studied concurrently before institution of immunosuppressive therapy all had antinuclear and/or smooth muscle antibodies, or LKM-1, at 1:40-1:640 and anti-ASGP-R at 1:300-1:2,100. None of these 18 had evidence of HCV infection and all were seronegative for anti-GOR. The findings indicate that the autoantibodies usually associated with AIH are rare in HCV infections but the virus can very occasionally induce a transient autoimmune response. Anti-GOR appears to be an antibody specifically related to HCV infection and is probably not a marker of induced autoimmunity, and it does not predict progression to chronic hepatitis.
