Diabetes mellitus (DM) is said to adversely affect transplant outcomes. The aim of this study was to investigate the impact of pre-existing and new-onset DM on liver transplantation (LT) recipients.
A single-center retrospective analysis of prospectively collected data of LT recipients (1990–2015) was undertaken.
Of the 2209 patients, 13% (n = 298) had Pre-DM, 16% (n = 362) developed post-transplant diabetes mellitus (PTDM), 5% (n = 118) developed transient hyperglycemia (t-HG) post-LT, and 65% (n = 1431) never developed DM (no DM). Baseline clinical characteristics of patients with PTDM were similar to that of patients with Pre-DM. Incidence of PTDM peaked during the first year (87%) and plateaued thereafter. On multivariate analysis (Bonferroni-corrected), nonalcoholic fatty liver disease and the use of tacrolimus and sirolimus were independently associated with PTDM development. Both Pre-DM and PTDM patients had satisfactory and comparable glycemic control throughout the follow-up period. Those who developed t-HG seem to have a unique characteristic compared with others. Overall, 9%, 5%, and 8% of patients developed end-stage renal disease (ESRD), major cardiovascular event (mCVE), and de novo cancer, respectively. Both Pre-DM and PTDM did not adversely affect patient survival, retransplantation, or de novo cancer. The risks of ESRD and mCVE were significantly higher in patients with Pre-DM followed by PTDM and no DM.
In this largest nonregistry study, patients with Pre-DM and PTDM share similar baseline clinical characteristics. Pre-DM increases the risk of ESRD and mCVE; however, patient survival was comparable to those with PTDM and without diabetes. Understanding the impact of PTDM would need prolonged follow-up.
