Transplanted fatty livers associated with worse prognosis for patients with HCV

A new study suggests that patients with hepatitis C (HCV) who need a liver transplant should not receive an organ with high levels of fatty deposits (a.k.a. hepatic steatosis). HCV recurrence was more frequent and earlier among those transplanted with such livers. These findings are in the January...
