ABSTRACT Seven patients with inactive ulcerative colitis and seven patients with Crohn's disease (5 inactive, 2 mildly active) received interferon treatment for associated chronic active hepatitis. Neither relapse (except in one patient) nor worsening of the clinical course of the inflammatory bowel disease was observed during treatment. According to these results chronic active hepatitis associated with inflammatory bowel disease can be treated with interferon without the risk of deteriorating the course of the inflammatory bowel disease.

    ABSTRACT: There is uncertainty about the efficacy and safety of treatment for hepatitis C virus (HCV) infection in patients with inflammatory bowel disease (IBD). IBD can become exacerbated during treatment with interferon (IFN) and serious adverse events, such as pancytopenia or hepatotoxicity, can be compounded by drug interactions. We investigated the risk of exacerbation of IBD during HCV therapy and the rate of adverse effects of concomitant therapy for HCV and IBD. We also evaluated the efficacy of HCV treatment in the IBD population. We conducted a retrospective review of all patients who underwent IFN-based treatment for HCV at the Mayo Clinic in Rochester, Minnesota from 2001 through 2012. Exacerbation of IBD was evaluated by clinical, endoscopic, and histologic parameters during antiviral therapy and the ensuing 12 months. Hematologic toxicity was assessed by levels of all 3 cell lineages at baseline and during therapy. Efficacy of antiviral treatment was assessed by serum levels of HCV RNA until 24 weeks after completion of therapy. We also conducted a detailed Medline database search and reviewed the literature on this topic. We identified 15 subjects with concomitant IBD (8 with ulcerative colitis and 7 with Crohn's disease). Only 1 patient experienced an exacerbation of the disease during therapy; symptoms were controlled with mesalamine enemas. Another patient developed a flare shortly after completing antiviral therapy; symptoms returned spontaneously to baseline 2 weeks later. All subjects experienced an anticipated degree of pancytopenia while on IFN-based therapy. The rate of sustained virologic response was 67 %. A concise review of available literature regarding the safety and efficacy of HCV treatment in IBD patients is also presented; although limited, the published data appears to support the safety of treatment with IFN in patients whose IBD is under control. In conjunction with data from the literature, our findings indicate that the efficacy and safety of HCV therapy with IFN and ribavirin for patients with IBD are comparable to those of subjects without IBD.

    ABSTRACT: Ulcerative colitis (UC) is an immune disorder of the gastrointestinal tract which has been reported to be precipitated by interferon (IFN) therapy. We describe the results of a literature review of cases in which the development or exacerbation of UC was coincident with IFN and/or ribavirin (RIB) treatment for chronic hepatitis C. We summarized the studies on the effectiveness of IFN for UC or Crohn's disease, which were primarily carried out in Europe and the USA. In the nine reported cases of UC exacerbation by IFN therapy in Japan, seven involved IFN-α, one involved IFN-α2b plus RIB, and the other involved IFN-β; thus cases induced by IFN-α were more common. The period between the initiation of IFN treatment and the development or exacerbation of UC varied widely among the reported cases (from 1 day to 4.5 years). The reports have all assumed a cause-and-effect correlation between IFN treatment and UC. However, although combination therapy of IFN and RIB has become widespread in Japan, UC development or exacerbation induced by IFN has not increased concurrently. Conversely, numerous studies reporting the effectiveness of IFN for treating UC and Crohn's disease have been published in Europe and the USA. One reason for this finding may be the difference in the balance of T helper cell 1 and T helper cell 2 between populations.
