Abstract
Objective: The amount of evidence suggests that the apoptosis marker M30-antigen (an antibody that recognizes the cytokeratin-18 fragment) has an association with hyperglycemia.
Material and Methods: In this study, serum M30 levels of 145 patients diagnosed with prediabetes (n = 28) and type 2 diabetes, which was divided into four groups according to their HbA1c levels, were measured. The health control group (n = 24) was composed of healthy individuals. Serum concentrations of M30 antigen were measured using an enzyme-linked immunosorbent assay system and expressed as mean ± SD. HbA1c concentration was determined by boronate affinity technology according to NGSP standards.
Results: M30 levels were comparable in the healthy control group (64,39±3,9 U/L) and prediabetes group (82,07±13,7). Type 2 diabetes Groups A, B, C, and D had levels of 109,38±16 U/L, 117,46±14,3 U/L, 173,69±48,1 U/L, and 163,40±37,3 U/L, respectively. The analysis of the data has shown that serum levels of M30 in the control and prediabetes groups were significantly lower than Type 2 diabetes Groups C and D (p=0.043). When all groups were taken into consideration, a significant relationship was found between HbA1c and serum M30 levels (r=0.231, p=0.002).
Conclusion: Apparently, the increase in glycemia is followed by a rise in the serum levels of the, suggesting that apoptosis occurs as a secondary effect immediately after hyperglycemia.
