Due to the large amount of blood and blood-derivates used during orthotopic liver transplantation (OLT) one light expect a bigb prevalence of C hepatitis in liver tramplanted patients. The ain of tbis retrospective study was to assess tbe prevalence of bepatitis C virus antibodies (SCv Ab) and their follow-up in a series of 61 OL? patients. The prevalence of serum antibodies to hepatitis C viW was assessed by ao ELISA test (Ortho D:qnostic System). Indications were cirrhosis in 26 cases, primarybiliary cirrhosis in 6 cases, liver cancer in 11 cases, fslainant hepatitis in 2 cases and alveolar echin-is in 17 cases. Sera ware tested before OLT and every tuo lontbs after. Twenty-nine patients anti-8Q negative before OL? remained negative after (group 1). Four patients seropositive before OLT reeained seropositire after (group I). Tueaty-eight patients seropositive before OLT, became seroneqativa after (group 2). and 3 patients seroneqatire before OLT became seropositive after (group 3). The prevalence of seroconversion ~1s 9.3 t (3/32). Tbe prevalence of seropositive patients after OLT was 11 t (I/(.4). The hisb nuaber of seropositive patients before OLT (1 patient out of 2) appeared related to false positive results due to a bypergamaqlobulinemia.

Although IFN reduces serum ALT levels in patients with chronic C-hepatitis. changes induced in liver hi&logy have not bocn completely churcmizcd. We mmlircd these changer and noticed I& appearance of new hismlogiul findings d&G treatment with rlFN alpha-Zb (5 MU day/2 mo. 3 MU dw/4 mo. and 1 MU liw/S mo). This 1 year protocol included 26 palicnu wilh chronic active C hepmitis on biopsy upon entry: 22 (85%) were anti-HCV positive. Histology was classified according to Knodell Index (HAI). Mcee sewn ALT level before envy was 241 f 105 U/L. Twenty prlienu (77%) normalized ALT during treatmel. In 22 puiems a second biopsy was done and HA1 was compared (p < 0.001) before (mean 10.1. range 6-151 and after (mean 5.5. range l-111 IFN tremmcm.
