Toward Zero Hepatitis C Virus-Related Mortality as a Prerequisite for the Release of Resources in a Center for Follow-up of Liver Transplant

Taking charge of a liver transplanted (LT) patient implies not only to follow up the transplanted organ (eg, immunosuppression and cancer risk) but also to deal with the prevailing patient's active problems. The recurrence of hepatitis C on the graft has historically been one of the main active problems to be addressed, leading to 30% to 40% mortality per se in these patients and has involved many resources in the hepatological centers responsible for the follow-up. We verified how much the availability of the new drugs with direct-acting antiviral agents (DAAs) against hepatitis C virus (HCV) has impacted the mortality within the assisted population, changing its characteristics and addressing new clinical issues in the LT-patients. We performed a retrospective comparison between 230 LT patients followed up during pre-DAA era (group 1, with 88 HCV RNA-positive) and 244 patients observed from 2014 onward when DAAs became available (group 2, with 79 HCV RNA-positive). Fifty-two antiviral therapies were performed in group 1 with 18 sustained virologic response (SVR) (35%) and 53 treatments, of which 37 were retreatments, in group 2 with 51 SVR (96%), P = .0001. Deaths for HCV-related causes were 19 of 33 (57%) in group 1 and 7 of 24 (24%) in group 2, P = .01. The Kaplan-Meier showed a dramatic reduction in excess mortality in HCV-LT patients after the availability of DAAs. These results suggest that HCV is no longer the main active problem of follow-up in liver transplants, therefore the resources can be relocated to take care of other clinical aspects.
