Effect of Hepatitis C Viremia on Posttransplant Diabetes Mellitus in Liver Transplant Recipients.

INTRODUCTION

Posttransplant diabetes mellitus (PTDM) can increase morbidity and mortality in liver transplant recipients. Although hepatitis C seropositivity is a known risk factor for PTDM, the impact of viremia versus no viremia at time of transplant is unknown.

PROJECT AIMS

This program evaluation sought to compare PTDM in hepatitis C seropositive patients with and without viremia at the time of liver transplant.

DESIGN

This single-center retrospective review included adult hepatitis C seropositive liver transplant recipients transplanted between January 1, 2010 to September 5, 2017 without pretransplant diabetes. Primary outcome was PTDM within 1 year. Secondary outcomes included evaluating 1-year posttransplant death-censored graft loss, mortality, and metabolic outcomes.

RESULTS

Fifty-seven liver transplant recipients with hepatitis C were included, of which 53% (n = 30) were viremic at transplant. Baseline characteristics were similar between groups. Significantly more patients with pretransplant viremia developed PTDM by 1-year posttransplant compared to the patients without viremia (43% vs 11%, = 0.01). There were no differences between groups outside of more patients with viremia requiring antihypertensives by 1-year posttransplant compared to patients without viremia (57% vs 22%, = 0.01).

CONCLUSION

Liver transplant patients with hepatitis C viremia at transplant were more likely to develop PTDM at 1 year compared to those without pretransplant viremia. This is an added consideration when deciding the timing of direct-acting antiviral (DAA) utilization in the context of liver transplant for hepatitis C seropositive patients.
