Is GDF-15 level associated with gestational diabetes mellitus and adverse perinatal outcomes?

OBJECTIVE

Growth differentiation factor-15 (GDF-15), the new member of transforming growth factor (TGF)-beta family, is released as a response of oxidative stress, inflammation and tissue injury. We aimed to determine GDF-15 levels in patients with Gestational Diabetes Mellitus (GDM) and the relation between GDF-15 and adverse perinatal outcomes.

MATERIALS AND METHODS

Forty pregnant women with GDM (receiving diet and insulin therapy) and forty healthy pregnant women as control group participated in this current study. GDF- 15 levels were analyzed by enzyme-linked immunosorbent assess kit.

RESULTS

The median serum GDF-15 level was measured higher in patients with GDM, and it was statistically meaningful (p: 0.000). Logistic regression analysis indicated that with the increase of GDF-15 level, the risk of GDM diseases increases as well. (P: 0.001, OR = 1.009; 95% CI = 1.003-1.014). There were no differences between GDF-15 levels and perinatal outcomes.

CONCLUSION

We concluded that higher GDF-15 levels are related to GDM in the third trimester. The optimal GDF-15 cut-off value was measured as 326 pg/ml for the diagnosis of GDM with 70% sensitivity and 60% specificity in our study. Further studies are needed to show the significance of GDF-15 as a biomarker for the disease.
