Hyperleptinemia as a risk factor for post-transplant diabetes mellitus development after kidney transplantation

Adipose tissue is involved in the synthesis of hormones that have an impact on food intake regulation, control of insulin sensitivity or regulation of inflammatory processes. The aim of this study was to determine the importance of adipocytokines and interleukins levels for the development of post-transplant diabetes mellitus (PTDM) after kidney transplantation (KT).

In the prospective analysis, the studied sample (n = 104) was divided into the control group, prediabetes group and PTDM group. Prior to transplantation, and subsequently, at 3, 6 and 12 months after KT, we recorded the basic characteristics of the donor and recipient, including parameters reflecting graft function, metabolic and anthropometric parameters. At the same time, we monitored the levels of adiponectin, leptin and interleukins during the monitored period.

Using multivariate logistic regression, we identified hyperleptinemia 12 months after KT as an independent risk factor for PTDM development 1 year after KT [OR 1.0320; 95% Cl 0.9785-1.0884 (p=0.0038)]. At the same time, we confirmed that age at the time of KT is also an independent risk factor for PTDM [OR 1.0903; 95% Cl 1.0149-1.1714 (p=0.0180)].

We confirmed that elevated leptin level 12 months after KT is associated with the development of PTDM (Tab. 3, Fig. 4, Ref. 22). Text in PDF www.elis.sk Keywords: adipocytokines, interleukins, post-transplant diabetes mellitus, kidney transplantation, leptin.
