Intravenous interferon administered during liver transplantation is not effective in preventing hepatitis C reinfection.

BACKGROUND: Post-transplant hepatitis C is a major challenge after liver transplantation (LT). Antiviral therapy is associated with lower efficacy in the post-transplant setting. AIMS: The purpose of this study was to determine the safety and effect of intravenous interferon (IFN) during the anhepatic phase of LT on hepatitis C viral load. METHODS: Fifteen consecutive subjects undergoing liver transplant for hepatitis C cirrhosis were enrolled in the study, ten of which received study drug and five subjects served as controls. Cases received weight-based ribavirin and subcutaneous IFN at time of incision followed by intravenous IFN at the start of the anhepatic phase. Adverse events and viral levels were recorded. Repeated measures ANOVA was employed to test for differences over time, between the groups, and time by group interaction. RESULTS: All subjects had genotype 1 virus. Hepatitis C viral load was lower at week 4 in cases compared to controls (769,004 ± 924,082 IU/ml and 2,329,896 ± 3,731,749 IU/ml, respectively), but did not reach statistical significance (p = 0.50). Three subjects developed adverse events related to IFN including pulmonary edema, rejection, and neutropenia. CONCLUSIONS: Intravenous IFN administered during the anhepatic phase of liver transplant did not prevent graft reinfection and was associated with manageable adverse events. This regimen could be further studied if direct acting antiviral agents alone are insufficient for treating post-transplant hepatitis C.

Liver transplantation for acute liver failure at 11-week gestation with successful maternal and fetal outcome.

Acute liver failure (ALF) during pregnancy is very uncommon. Pregnancy-specific liver conditions like hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome and acute fatty liver of pregnancy can cause ALF at term or postpartum, but, typically occur during the third trimester. Most of these patients recover spontaneously after delivery, but, on occasion, they require liver transplantation in the postpartum period. However, ALF during the first and second trimester of pregnancy requiring antepartum liver transplantation is rare. Only fifteen cases of liver transplantation during pregnancy have been reported, and very few occurred during the first trimester. We report a Woman who developed acute liver failure during the first trimester of pregnancy and underwent successful liver transplantation at 11-week gestation, followed by successful delivery of the fetus at 30 weeks. To our knowledge, this is the earliest case of successful liver transplantation during pregnancy followed by successful fetal outcome. We discuss management of the patient and fetus before, during, and after liver transplantation and review the literature on antepartum liver transplant in pregnancy.

Brief communication: severe hepatotoxicity of telithromycin: three case reports and literature review.

BACKGROUND: Telithromycin is a ketolide antibiotic approved by the U.S. Food and Drug Administration for acute bacterial infections causing sinusitis, bronchitis, and community-acquired pneumonia. OBJECTIVE: To describe 3 cases of severe hepatotoxicity in patients receiving telithromycin. DESIGN: Case reports. SETTING: A tertiary care medical center. PATIENTS: 3 previously healthy patients who had recently taken telithromycin and took no other prescription medications. MEASUREMENTS: Serologic, histologic, and liver function tests. RESULTS: Within a few days of receiving telithromycin, the patients presented with acute hepatitis. All had jaundice and markedly abnormal results on liver function tests. Results of viral serologic tests were negative. One patient spontaneously recovered, 1 required orthotopic liver transplantation, and 1 died. Histologic examination in the latter 2 patients showed massive hepatic necrosis. LIMITATIONS: Two patients had some history of alcohol use. The frequency of severe telithromycin-related hepatotoxicity cannot be established with case reports. CONCLUSIONS: Telithromycin can cause severe hepatotoxicity. Caution is advised in prescribing this drug pending additional postmarketing surveillance data.
