Risk factors associated with diabetes after liver transplant

ABSTRACT
Objective:
Post-transplant diabetes mellitus (PTDM) is a common metabolic complication after liver transplant that negatively affects a recipient’s survival and graft function. This study aims to identify risk factors associated with diabetes after liver transplant.
Materials and methods:
This is a cross-sectional study conducted from September to November 2019. Data collection was performed by chart review, and patients were divided into 3 groups: patients without diabetes mellitus (DM), patients with pre-transplant diabetes mellitus, and patients with PTDM.
Results:
Two hundred and forty-seven patients’ medical charts were screened, and 207 patients were included: 107 without DM, 42 with pre-transplant DM, and 58 with PTDM. The leading cause for liver transplant was hepatitis C, followed by hepatocellular carcinoma secondary to alcohol. There was a higher exposure to tacrolimus in patients without DM ( P = 0.02) and to ciclosporin in patients with pre-transplant DM, compared to others ( P = 0.005). Microscopic interface inflammatory activity was more severe in patients without DM as well as those with PTDM ( P = 0.032). There was a higher prevalence of steatosis in recipients with pre-transplant DM than there was in others ( P < 0.001). Multivariate logistic regression identified the following independent risk factors for DM: cirrhosis due to alcohol, hepatitis C, and triglycerides. For PTDM, these independent risk factors were cirrhosis due to alcohol, hepatitis C, and prednisone exposure.
Conclusion:
Alcoholic cirrhosis is a risk factor for PTDM in liver recipients. Liver transplant recipients with a pre-transplant history of cirrhosis due to alcohol, hepatitis C, and prednisone exposure deserve more caution during PTDM screening.
