    Notizen: Summary In previous studies cytomegalovirus (CMV) infection was identified as one risk factor in the development of vanishing bile duct syndrome (VBDS) after orthotopic liver transplantation (OLT), but its precise role in relation to the pathogenesis of tissue damage is uncertain. In the present study a-interferon (α-IFN) expression in the liver was studied as an indirect marker of viral infection in serial liver biopsies from 42 patients following OLT. α-IFN was identified more frequently in the bile duct cytoplasm of patients developing VBDS, with or without evidence of preceding CMV infection (7/8 and 4/5 cases, respectively), when compared with patients with acute CMV but without evidence of VBDS (6/19 cases; P〈0.05) or those with neither complication (2/10 cases; P〈0.01). α-IFN was detectable in bile duct cytoplasm for a longer period in patients developing VBDS than in those with acute CMV infection alone (median 14 weeks and range 9–19, median 6 weeks and range 1–11 weeks, respectively; P〈 0.025). These data indicate that persistent CMV infection of bile duct cells is a likely co-factor linked to progression to VBDS, but the processes that allow persistent viral infection and bile duct destruction remain to be determined.

    Notizen: Abstract Hepatitis C infection following orthotopic liver transplantation may lead to progressive chronic graft dysfunction. In this study, seven liver transplant recipients with chronic allograft dysfunction due to hepatitis C infection (one acquired and six recurrent infections) were treated with oral ribavirin for 6 months. Symptoms of lethargy, nausea and anorexia improved in all patients within 2 weeks of starting the drug, with a fall in serum AST of at least 40% by this time. Ribavirin-induced haemolysis was clinically significant in three patients, necessitating a reduction in the daily dose of ribavirin from 1.2 g to 0.2 g. Comparison of the pre- and post-treatment biopsy specimens in the four patients who tolerated the full dose of ribavirin and who had normal AST levels at the end of 6 months of treatment showed significant histological improvement with reduction in either lobular or periportal inflammation in all of the patients and a reduction in periportal fibrosis in one patient. HCV RNA remained detectable in serum in all of the patients at the end of the study.
