Changes of serum pentraxin-3 and hypersensitive CRP levels during pregnancy and their relationship with gestational diabetes mellitus.

Abstract

To investigate the changes of inflammatory factors pentraxin 3 (PTX3) and hypersensitive C-reactive protein (hs-CRP) during pregnancy and their relationship with gestational diabetes mellitus (GDM). The nested case-control study method was used. Eighty non-obese single-pregnant women diagnosed with GDM were included into the case group (GDM, n = 80), together with another eighty pregnant women with normal glucose tolerance were matched in the same period and divided into the control group (CON, n = 80), for detecting multiple biochemical indicators in different pregnancy stages by ELISA. The serum levels of PTX3 and hs-CRP in pregnant women increased with the increase of gestational age (p < 0.001, p < 0.001). The levels of PTX3 and hs-CRP in group GDM were significantly higher in the middle and late pregnancy stages than group CON (p < 0.01, p < 0.05; p < 0.05, p < 0.05). PTX3 was positively correlated with hs-CRP, body mass index (BMI), fasting plasma glucose (FPG), and homeostasis model assessment of insulin resistance (HOMAIR). PTX3 and hs-CRP may be related to the pathogenesis of GDM, and they are significantly increased in the second trimester, which provides a new idea for early prevention and treatment of GDM and risk prediction of long-term cardiovascular diseases.
