The present trial has several limitations including the small sample size and the relatively short treatment duration. Inclusion criteria and the primary endpoint were based on OGTT, a method that is regarded as the gold standard for NODAT detection and diagnosis (57). However, only one OGTT was performed in the present study at baseline as well as 3 and 4 months thereafter. Whether continuous treatment with DPP-4 inhibitors may prove beneficial in NODAT patients will also need to be examined further.
However, we were able to demonstrate that the DPP-4 inhibitor vildagliptin was highly efficient in achieving adequate glycemic control after short-term treatment. Furthermore, vildagliptin was expectably safe regarding hypoglycemic episodes. Adverse events were mild and appeared at similar rates in both study arms. Thus, vildagliptin proved to be a safe and efficient treatment option against NODAT in KTRs, and provides a suitable alternative for this specific form of diabetes.
