New-onset diabetes mellitus after liver transplantation in the patients with acute liver failure

Background To detect the frequency and possible risk factors of new-onset diabetes after liver transplantation in the patients with acute liver failure. The frequency of new-onset diabetes after transplant (NODAT) is 5-30% in liver transplant recipients. We aimed to analyze the frequency and predictors of NODAT in the patients undergoing liver transplantation due to acute liver failure. Methods Adult patients undergoing liver transplantation due to acute liver failure were analyzed retrospectively. The patients with chronic liver failure or diabetes were excluded. We measured pretransplant random blood glucose and posttransplant fasting blood glucose. NODAT was diagnosed according to principally 1st month fasting blood glucose (group 1 < 100, group 2 100-125, group 3 > 125 mg/dL). The participants were subgrouped according to age, gender, body mass index, etiology, antiviral medication, thyroid function, pretransplant random blood glucose, donor type, immunosuppressive drug, common infection, and surgical complication. Results Mean age of total 91 patients was 33.48 (+/- 13.35), and 52.7% (n = 48) of them was female. The ratio of NODAT was 26.98% on the 1st month. NODAT group had a higher pretransplant random blood glucose than the others. Pretransplant hyperglycemia increased the risk of NODAT by 4.065 times (p = 0.018). Conclusion We showed that pretransplant hyperglycemia increased NODAT risk by 4 times, but hypoglycemia did not affect. So, pretransplant hyperglycemia should be controlled also in the patients with acute liver failure as in the patients with chronic liver failure.
