Relationship Between Insulin Resistance and Mean Platelet Volume in Gestational Diabetes Mellitus.

Objectives: A few studies have investigated the relationship between mean platelet volume (MPV) and gestational diabetes mellitus (GDM), and in these studies the relationship between MPV and insulin resistance has not been analyzed. Our aim in this study was to compare MPV values of the pregnant women with or without GDM and evaluate the relationship between MPV and homeostasis model assessment insulin resistance index (HOMA-IR) in pregnant women.

Materials And Methods: One hundred and fourteen with GDM measurements being obtained before any dietary advice or therapy with insulin or hypoglycemic agents were given, and 76 with healthy pregnant women were included the study.

Results: In the group with GDM, MPV value was found to be significantly higher than that of the control group (10.2 fl [8.0-12.2] vs. 9.9 fl [5.81-10.9], P = 0.004). HOMA-IR value was detected to be significantly higher in the group with GDM (2.46 [1.5-5.88] vs. 1.30 [0.17-2.92], P < 0.001). A positive correlation between MPV and HOMA-IR was found (r = 0.30, P = 0.002).

Conclusion: We have shown that MPV was significantly elevated in GDM patients when compared to healthy pregnant women. Furthermore, we found that there was a positive correlation between MPV and HOMA-IR.
