Background: Several studies from Europe have reported a high prevalence (9% to 32%) of chronic hepatitis C virus (HCV) infection in patients with B-cell non-Hodgkin lymphoma. It has been suggested that HCV plays a role in the pathogenesis of B-cell non-Hodgkin lymphoma.

Few studies have examined causes of death in long-term survivors of orthotopic liver transplantation (OLT). We reviewed causes of death among 299 adult liver transplant recipients who survived more than 3 years after OLT at 2 centers. Thirty-eight of the 299 patients subsequently died. Nonhepatic causes accounted for 22 of 38 late deaths (58%). Death caused by malignancies occurred in 9 patients between 3.3 and 8.0 years after OLT. Eight patients died of cardiovascular complications. The 6 patients who died of myocardial infarction had risk factors for coronary artery disease. Hepatic failure caused by recurrent liver disease or chronic rejection accounted for 16 of 38 late deaths (42%). These 16 patients were younger than patients who died of nonhepatic complications (mean ages, 50.7 v 62.1 years; P ‫؍‬ .001). However, the mean interval between OLT and death was similar among patients who died of nonhepatic versus hepatic causes. Nine patients had recurrent liver disease leading to death, and 8 of 9 patients had recurrent chronic hepatitis C virus (HCV) infection. Chronic rejection resulting in graft failure and death occurred in 7 patients. In summary, de novo malignancies and cardiovascular complications accounted for more than half the late deaths. Patients who died of nonhepatic causes were significantly older than patients who died of hepatic causes. Chronic rejection and recurrent HCV infection accounted for the majority of hepatic causes of death. With longer followup, graft failure resulting from recurrent HCV infection will become the major cause of death in late survivors. (Liver Transpl 2001;7:811-815.)

Interferon-alpha therapy is of proven efficacy in chronic hepatitis C, but it is not universally effective and may be associated with intolerable side effects. Ribavirin is a nucleoside analog with a broad spectrum of antiviral action. We conducted an uncontrolled pilot study of ribavirin therapy in 13 patients with chronic hepatitis C. Ribavirin was given for 6 mo, in a dose that was increased, at 2-mo intervals, from 600 mg to 1,000 mg to 1,200 mg/day. Serum ALT levels gradually decreased in all 13 treated patients; the mean percentage of decrease was 67% (from 210 U/L [range = 109 to 593] to 63 U/L [range = 22 to 108 U/L]; p = 0.0006) after 6 mo of treatment. Serum aminotransferase levels fell to the normal range in four patients (31%). In the 3 to 6 mo after cessation of ribavirin therapy, serum aminotransferase activities gradually rose to near pretreatment levels in all but one patient. Therapy was associated with a significant decrease in the geometric mean titer of hepatitis C virus RNA in serum (1:1,981 vs. 1:199; p less than 0.02) although no patients lost hepatitis C virus RNA from serum during therapy. No significant improvement was seen in liver histological appearance. Ribavirin therapy resulted in mild, reversible hemolysis; no patient exhibited symptomatic anemia. These findings suggest that ribavirin has a beneficial effect in patients with chronic hepatitis C, although further studies are needed to determine how ribavirin is best used.

Liver allograft provided renal graft immunoprotection if both organs are transplanted simultaneously (immunogenetic identity), but not for kidneys transplanted subsequently.
