Background. A more rapid and aggressive course of hepatitis B virus (HBV)-related and hepatitis C virus (HCV)-related infection in organ transplant recipients has been described. Interferon alfa is the most accepted drug for treating HBV and HCV chronic infections. However, the use of interferon alfa-N3 has been contraindicated in heart transplant (HTx) recipients because of the hypothesized greater risk of triggering acute cellular rejection. The aim of this clinical pilot study was to evaluate tolerability, safety, and efficacy of natural leukocyte interferon alfa in the treatment of chronic HBV and HCV in HTx recipients. Methods. Seven HTx recipients were enrolled in the study: two with HBV, four with HCV, and one with combined HBV-HCV chronic infection. The patients had a mean follow-up after heart transplantation of 8.5±3 years, before starting interferon alfa-N3 treatment at a dose of 6 MU three times per week, intramuscularly for 12 months. Results. All patients completed the treatment with no major side effects. No unexpected episodes of acute cellular rejection were observed during the treatment. Mean aminotransferase serum levels were significantly lower than before transplantation at 3 (P<0.03), 6 (P<0.02), and 12 (P<0.02) months of treatment and at the 12-month follow-up (P<0.02). A complete and sustained response was achieved in all subjects with HBV-related chronic hepatitis, whereas sustained virologic response was observed in one of four HCV patients. Conclusions. The preliminary data emerging from our study indicate that natural leukocyte interferon alfa-N3 can be safely administered in HTx recipients with chronic HBV or HCV viral hepatitis. Further studies with larger numbers of patients are needed to assess the efficacy of interferon alfa-N3 on HCV virologic response.

Abstract

Background. A more rapid and aggressive course of hepatitis B virus (HBV)-related and hepatitis C virus (HCV)-related infection in organ transplant recipients has been described. Interferon alfa is the most accepted drug for treating HBV and HCV chronic infections. However, the use of interferon alfa-N3 has been contraindicated in heart transplant (HTx) recipients because of the hypothesized greater risk of triggering acute cellular rejection. The aim of this clinical pilot study was to evaluate tolerability, safety, and efficacy of natural leukocyte interferon alfa in the treatment of chronic HBV and HCV in HTx recipients. Methods. Seven HTx recipients were enrolled in the study: two with HBV, four with HCV, and one with combined HBV-HCV chronic infection. The patients had a mean follow-up after heart transplantation of 8.5±3 years, before starting interferon alfa-N3 treatment at a dose of 6 MU three times per week, intramuscularly for 12 months. Results. All patients completed the treatment with no major side effects. No unexpected episodes of acute cellular rejection were observed during the treatment. Mean aminotransferase serum levels were significantly lower than before transplantation at 3 (P<0.03), 6 (P<0.02), and 12 (P<0.02) months of treatment and at the 12-month follow-up (P<0.02). A complete and sustained response was achieved in all subjects with HBV-related chronic hepatitis, whereas sustained virologic response was observed in one of four HCV patients. Conclusions. The preliminary data emerging from our study indicate that natural leukocyte interferon alfa-N3 can be safely administered in HTx recipients with chronic HBV or HCV viral hepatitis. Further studies with larger numbers of patients are needed to assess the efficacy of interferon alfa-N3 on HCV virologic response.
