Gordon, MD C ONTENTS INTRODUCTION AUTOIMMUNE MANIFESTATIONS OF VIRAL HEPATITIS AUTOIMMUNE EFFECTS OF IFN-α T REATMENT OF CHRONIC VIRAL HEPATITIS IN PATIENTS WITH PRE-EXISTING AUTOIMMUNE DISORDERS CONCLUSION REFERENCES INTRODUCTION There exists an intricate relationship between chronic viral hepatitis, its treatment, and autoimmunity. A vast array of extrahepatic manifes- tations is associated with hepatitis C (1) and, to a lesser extent, hepatitis B (2); many of these conditions are mediated through autoimmune mech- anisms. Shortly after the release of interferon α-2b (IFN-α2b) for the treatment of these viral infections came reports of autoimmune disorders that were either caused or unmasked by the use of this agent. Because patients with known autoimmune diseases were routinely excluded from IFN treatment trials, literature regarding the use of this agent in this impor- tant patient group is scant. Anecdotal reports and a review of the avail- able literature, however, provide valuable clinical information, and shed light on this intriguing, but poorly documented subject. 170 Ghaith and Gordon The treatment of chronic viral hepatitis in patients with autoimmune disorders involves an analysis of complex interactions of multiple factors, with many confounding variables. Thus, there exists autoimmune mani- festations of viral hepatitis in the absence of IFN therapy; autoimmune adverse effects of IFN itself in the patient with chronic hepatitis C virus without underlying autoimmunity; and the effect of IFN on the patient with viral hepatitis, who also has an underlying autoimmune disease. AUTOIMMUNE MANIFESTATIONS OF VIRAL HEPATITIS Chronic viral hepatitis, both type B (3) and type C, has been associated with a spectrum of autoimmune phenomena. McMurray and Elbourne (4) summarized many of the reported autoimmune complications of HCV hepatitis (Table 1). Some of these HCV-related entities, such as membranous glomerulonephritis (GN) (5), cryoglobulinemia, and asso- ciated vasculitis (6–9), tend to improve following successful treatment and viral eradication. Among HBV-associated autoimmune phenom- ena, the HBV-related proteinuria (10) and polyarteritis nodosa (11–16) usually improve, following successful IFN antiviral therapy. Neverthe- less, the opposite may also occur: Worsening of cryoglobulinemic neuro- pathy and fatal bleeding secondary to vasculitic gastritis occurred when IFN-α was given to a hepatitis C patient with highly symptomatic cryo- globulinemia (17), in whom steroids had not been tried before IFN. It is not clear whether corticosteroids should be started before, or along with, IFN in the patient with symptomatic cryoglobulinemia. In addition, HCV- associated thyroid disease (18–20) and lichen planus (21–23) may worsen or flare during IFN therapy. Thus, it would appear that autoimmune com- plications of chronic viral hepatitis pursue a variable course during IFN therapy, and that clinicians must approach each case individually. AUTOIMMUNE EFFECTS OF IFN- αα αα α Infections are cytokines with both antiviral and antiproliferative prop- erties. IFN-α increases the expression of human lymphocyte antigen (HLA) class I and II, which results in a magnified activity of both helper and cytotoxic lymphocytes, and subsequent upregulation of the immune system. This, in turn, can lead to the induction of a new autoimmune disease, or to the exacerbation of an existing autoimmune disease. Shortly after IFN-α2b was Food and Drug Administration-approved for the therapy of hepatitis C, came reports that showed a worsening of amino- transferase levels in HCV patients during therapy, with an autoimmune Chapter 9 / Treatment of Chronic Viral Hepatitis in AIDs Patients 171 hepatitis-like picture (24–27). Over the past 10 yr, numerous reports have described de novo autoimmune conditions that appeared to be hastened by IFN therapy (Table 2). Most of these manifestations appear to improve after the cessation of interferon (IFN). Okanoue et al. (28) studied the IFN-related autoimmune complica- tions of 677 patients with chronic HCV who underwent antiviral therapy. These conditions included autoimmune thyroiditis (18 patients); hemo- lytic anemia (two patients); rheumatoid arthritis (RA) (two patients); immune-mediated thrombocytopenia (ITP), psoriasis, and systemic lupus erythematosus (SLE)-like syndrome (one patient each). In that retrospec- tive study, the autoimmune complications generally occurred from 12 to 20 wk after starting IFN. After cessation of therapy, most of these entities completely resolved.

TREATMENT OF CHRONIC VIRAL HEPATITIS IN PATIENTS WITH PRE-EXISTING AUTOIMMUNE DISORDERS The role of IFN therapy in patients with chronic viral hepatitis and a pre-existing autoimmune disorder raises separate issues: What is the course of the autoimmune disorders during IFN therapy? What is the virologic response to IFN in such patients? In addition, does the mere presence of circulating autoantibodies define the existence of an auto- immune disorder, and does the presence of such antibodies affect the response to IFN? The following discussion, therefore, focuses on both the role of IFN in the patient with autoantibodies, but without autoim- [...]...
