Plasma high-sensitivity C-reactive protein measured prior to transplant is related to prediabetes in first-year kidney transplant recipients: A single-center cross-sectional study in Vietnam.

Aim: To determine the rate of prediabetes among and the pre-transplant plasma high-sensitivity C-reactive protein (hs-CRP) value predictive of prediabetes in patients during their first year post-living donor kidney transplant.

Methods: A total of 538 patients underwent living donor kidney transplantation between January 2018 and December 2020, 413 of whom met the inclusion criteria for this study. All patients underwent oral glucose tolerance tests (OGTTs) with 75 g glucose/200 mL solution, starting 3 months post-transplant and repeating the test every 3 months for the first year. Clinical and paraclinical indicators and plasma hs-CRP concentrations were quantified the day prior to the transplant. Prediabetes was diagnosed according to the American Diabetes Association 2018 criteria as a 2-h OGTT result between 140 mg/dL (7.8 mmol/L) and 199 mg/dL (11.0 mmol/L).

Results: The rate of prediabetes among the study subjects was 38.3 % (158/413). Body mass index (BMI) and pre-transplant plasma triglycerides, high-density lipoprotein cholesterol (HDLC), and hs-CRP levels were related factors predictive of prediabetes in patients within the first year post-kidney transplant based on multivariate logistic regression and receiver operative characteristic curve models. Hs-CRP was the factor with the best predictive value (area under the curve = 0.89; p < 0.001).

Conclusions: Pre-transplant plasma hs-CRP levels were a good predictor of prediabetes in the first year post-living donor kidney transplant.
