We present 10 Italian patients with type 2b autoimmune hepatitis (anti-LKMI positivity) and HCV infection. 6 patients had IgG concentrations above the upper limit of normal and all had histological features of chronic autoimmune hepatitis or chronic persistent hepatitis or chirrosis. ANA and S[VIA were positive in 2 patients, pANCA in 3 patients. Anti-GOR were negative in all patients, 6 of them were HLA B8 DR3 and 2 HLA B8 DR4. Antibodies to HCV (tested by ELISA 2nd and 3rd generation) were positive in all patients and in 9 subjects were detected HCV RNA. The two patients with positivity for ANA and SMA were treated successfully with corticosteroids, but they relapsed after the drug withdrawal; the others received interferon, that had to be suspended in 2 patients because inducing an autoimmune thyroiditis. Although, at present, it is still not known if HCV is a really trigger factor in developing autoimmunity or it the two diseases are coincidental, the authors suggest that it is important for clinicians to use appropriate treatment strategies on the basis of the predominant illness.

Abstract
We present 10 Italian patients with type 2b autoimmune hepatitis (anti-LKMI positivity) and HCV infection. 6 patients had IgG concentrations above the upper limit of normal and all had histological features of chronic autoimmune hepatitis or chronic persistent hepatitis or chirrosis. ANA and S[VIA were positive in 2 patients, pANCA in 3 patients. Anti-GOR were negative in all patients, 6 of them were HLA B8 DR3 and 2 HLA B8 DR4. Antibodies to HCV (tested by ELISA 2nd and 3rd generation) were positive in all patients and in 9 subjects were detected HCV RNA. The two patients with positivity for ANA and SMA were treated successfully with corticosteroids, but they relapsed after the drug withdrawal; the others received interferon, that had to be suspended in 2 patients because inducing an autoimmune thyroiditis. Although, at present, it is still not known if HCV is a really trigger factor in developing autoimmunity or it the two diseases are coincidental, the authors suggest that it is important for clinicians to use appropriate treatment strategies on the basis of the predominant illness.
