AIM: To evaluate the effect of long-term treatment with leukocyte natural α-interferon (ln-α-IFN) plus ribavirin (RBV). METHODS: Forty-six patients with hepatitis C virus (HCV) recurrence received 3 MU three times a week of ln-α-IFN plus RBV for 1 mo; then, patients with good tolerability (n = 30) were switched to daily IFN administration, while the remaining were treated with the same schedule. Patients have been treated for 12 mo after viral clearance while non-responders (NR) entered in the long-term treatment group. Liver biopsies were planned at baseline, 1 year after sustained virological response (SVR) and at 36 mo after start of therapy in NR. MedCalc software package was used for statistical analysis. RESULTS: About 16.7% of genotype 1-4 and 70% of genotype 2-3 patients achieved SVR. Nine patients withdrew therapy because of non-tolerance or non-compliance. A significant improvement in serum biochemistry and histological activity was observed in all SVR patients and long-term treated; 100% of patients with SVR achieved a histological response (fibrosis stabilization or improvement) with a significant reduction in mean staging value (from 2.1 to 1.0; P = 0.0031); histological response was observed in 84% of long-term treated patients compared to 57% of drop-out. Six patients died during the entire study period (follow-up 40.6 ± 7.7 mo); of them, 5 presented with severe HCV recurrence on enrollment. Diabetes (OR = 0.38, 95%CI: 0.08-0.59, P = 0.01), leukopenia (OR = 0.54, 95%CI: 0.03-0.57, P = 0.03) and severe HCV recurrence (OR = 0.51, 95%CI: 0.25-0.69, P = 0.0003) were variables associated to survival. Long-term treatment was well tolerated; no patients developed rejection or autoimmune disease. CONCLUSION: Long-term treatment improves histology in SVR patients and slows disease progression also in NR, leading to a reduction in liver decompensation, graft failure and liver-related death.
