Materials and methods - Population‐based prospective cohort study in 273 pregnant women with markers measured four times during pregnancy and at 5‐year follow‐up.
Results - sCD163 was higher (25% at 14‐16 weeks, P < 0.001) and adiponectin lower (−17% at 14‐16 weeks, P < 0.01) early in pregnancy and at 5‐year follow‐up in GDM women, independent of BMI, and other GDM risk factors. Leptin, adiponectin, and chemerin were robustly associated with glucose metabolism throughout pregnancy while sCD163 was inversely associated with β‐cell function early in pregnancy in women with increased BMI. Finally, the markers at 14 to 16 weeks displayed modest discriminatory properties with regard to prediction of GDM (AUC < 0.7). Using a combination of fasting glucose and sCD163, 53% of GDM could be identified when 25% of the population scored positive suggesting some merit in a multimarker approach.
Conclusions - sCD163 and adiponectin were dysregulated in GDM, independent of body mass. None of the adipokines or monocyte/macrophage activation markers displayed clinically useful properties alone for early detection of GDM. Activation of monocytes/macrophages may be an important event in the early development of GDM.
