Autoimmune reactions in HBV and HCV

Z Michalska et al. Med Sci Monit. 2001 May.

Abstract

Background: Hepatotropic viruses HBV and HCV are capable of triggering autoimmune reactions (AIH). The aim of the study was the assessment of clinical course of AIH in patients with HBV and HCV, and the revision of treatment methods employed in these cases.

Material and methods: Among 120 patients with AIH and those qualified for antiviral therapy, 21 (17.5%) subjects were selected, including 16 with HCV (7 men and 9 women) and 5 with HBV (including 2 men and 3 women). AIH diagnosis was based on international criteria taking into account biochemical tests, autoantibodies and morphological picture of the liver. HBV infection was confirmed with the determination of HBV markers and HCV--with the presence of antiHCV and HCV RNA.

Results: The duration of infection at AIH diagnosis was difficult to assess in patients with HCV. AIH was diagnosed when patients were qualified for antiviral treatment. Three patients displayed high anti-LKM1, 8--ANA and SMA, two pts--ANA, two pts--SMA, one pt--ANA + pANCA and one--SMA + pANCA. Nine patients did not show hyperproteinaemia, and hypergammaglobulinaemia was not observed in 2 patients. Six patients suffered from other immunity disorders--thrombocytopenia, vasculitis, arthritis, visceral lupus erythematosus. The diagnosis of chronic hepatitis was confirmed by morphological examinations in 15 patients. Ten subjects received adrenocortical hormones, 3 patients were treated with adrenocortical hormones and azathioprine, 4 received interferon and 3 received no treatment. All patients with HBV proved HBeAg(-). In these patients, AIH symptoms developed 5-18 years after the diagnosis of HBV infection. Liver biopsy confirmed the diagnosis in 4 patients. SMA was observed in 2 subjects, ANA and SMA--in the remaining patients. All the subjects manifested typical biochemical changes as well as high IgG values. Extrahepatic exponents of immune process were observed in 3 patients. Three subjects were treated with Encorton (Prednisone), while 2 patients received Encorton and Azathioprine.

Conclusions: Patients with HBV and HCV infections may manifest the features of AIH in the course of the disease, which requires careful attention while selecting treatment.
