Background Methylglyoxal ( MG ) is a reactive‐dicarbonyl that is thought to contribute to the development of diabetes either as a precursor for advanced glycation end products or as a direct toxin. The present study was designed to determine plasma MG level in patients with newly diagnosed type 2 diabetes mellitus ( T2DM ) and to evaluate the relationship between MG and other parameters, such as oxidative stress and metabolic indices. Methods Methylglyoxal was measured by high‐performance liquid chromatographic/tandem mass spectrometry in plasma from 48 subjects with newly diagnosed T2DM . The relationship between two variables was analyzed using Spearman's correlation analysis. Multiple stepwise linear regression analysis was used to assess the association of plasma MG and other parameters. Results Plasma MG level in patients with newly diagnosed T2DM (65.2 ± 19.2 ng/mL) were significantly higher than that in control individuals (40.1 ± 11.1 ng/mL, P < 0.05). The plasma level of MG was positively correlated with the glycosylated hemoglobin A1c ( HbA1c , r = 0.670, P < 0.01) and malondialdehyde ( MDA , r = 0.694, P < 0.01). Multiple linear regression analysis revealed that both HbA1c and MDA are significant independent determinants of plasma MG level. Conclusions These findings suggest that increased plasma MG level is associated with the elevation of HbA1c and MDA in newly diagnosed T2DM patients.
