    In this work, we tested the strategy for the detection of T3cDM and early PC based on NMR metabolomics. ’H NMR spectroscopy was used to detect changes in the concentration of low molecular metabolites in the blood plasma of four groups: PC patients, long-term T2DM (lasting more than 5 years), new-onset diabetic patients (lasting less than 3 years, potential T3cDM) and healthy controls. The ChenomX software was used to identify 65 metabolites across all samples. Based on the concentrations of the identified metabolites, methods of pattern recognition (primarily PCA and OPLS-DA) and statistical tests (t-test and Wilcoxon rank sum test) were used to differentiate between the studied groups. The obtained results suggested a panel of biomarkers for the detection of PC. Within the group of new-onset diabetics, our proposed OPLS- DA model, (verified by Monte Carlo cross-validation), was able to predict possible T3cDM patients at risk of developing PC. Regarding such results, the suggested model might serve as a screening method for the early detection of PC.
