Background:
Many studies have reported the negative influence of diabetes and hypertension on morbidity and mortality in the general population. In liver transplantation (LT) recipients, prevalence of nonalcoholic fatty liver disease and metabolic syndrome is increasing. Hence, concerns over the negative influence of metabolic syndrome, including diabetes and hypertension, are growing. However, there have been few studies about the outcomes of LT recipients with diabetes with/without hypertension. We aimed to evaluate the impact of diabetes with/without hypertension on the outcomes of LT.
Methods:
Between May 2010 and October 2015, 814 LT recipients (median age, 51 [46-55] years; median MELD score, 13 [9-18]), without overt cardiovascular disease were retrospectively evaluated. To rigorously adjust for clinically confounding factors, a 1:2 propensity score matching analysis was performed. Kaplan-Meier survival curves and Cox proportional hazard regression analysis were performed to examine the association between diabetes with/without hypertension and all-cause mortality or graft survival rate.
Results:
There were 77 (9.5%) graft failures and 71 (8.7%) deaths during a median follow-up of 2.4 years. After 1:2 matching of 173 (21.3%) diabetic patients, no significant differences were evident in graft survival rate (log-rank test, P = .46; and hazard ratio [HR], 1.06; 95% confidence interval [CI], 0.55-2.06; P = .865) and all-cause mortality (log-rank test, P = .59; and HR, 1.06; 95% CI, 0.55-2.06; P = .727). Separate 1:2 matching was applied to a subgroup of 43 (5.3%) patients with diabetes and hypertension. This matching also showed no difference in graft survival rate (log-rank test, P = .45; and HR, 1.35; 95% CI, 0.43-4.27; P = .613) and all-cause mortality (log-rank test, P = .25; and HR, 1.87; 95% CI, 0.54-6.50; P = .325).
Conclusion:
Diabetes with/without hypertension does not have an impact on graft survival rate or all-cause mortality in LT recipients.
