Clinical Trial Summary

The first aim of this study is to describe maternal hormonal and inflammatory changes during pregnancy in women that differ metabolically (limited to women with type 2 diabetes, gestational diabetes and/or overweight). The second aim of this study is to examine maternal hormonal, inflammatory and metabolic factors associated with insulin sensitivity in human pregnancy.

Description:

This is a prospective observational study including app. 300 pregnant women from the outpatient clinics at Department of Obstetrics and Gynecology at Aalborg, Odense and Aarhus University Hospital. The study includes 50 healthy normal-weight women, 150 healthy overweight women, 50 women with gestational diabetes and 50 women with type 2 diabetes. Hormonal profiles and inflammatory markers will be measured at gestational week 8-10, 10-14, 18-22, 24-28 and 34-38. The blood samples will include HbA1c, glukose, insulin, C-peptid, lipid profile, liver enzymes, creatinine, FGF-21, TSH, Cortisol, human chorionic gonadotropin, estradiol, progesterone, prolactin, human placental lactogen, placental growth hormone, IGF-1, IGF-BP's, Leptin, Adiponectin, GLP-1, GIP, hs-CRP, IL-6, IL-10, IL-1α, IFN-ɣ, TNF-α, ICAM1, VCAM and CD163. In addition to this, exosomes will be isolated precisely and profiling of the content of exosomes will be performed using in vitro assays. Proteomics and miRNAs sequencing will be employed. Height, weight, and blood pressure will be measured at every visit and a urine sample will be collected. Insulin sensitivity will be estimated using the homeostasis model assessment, IS-HOMA, based on fasting insulin and glucose concentrations.

Type	Measure	Description	Time frame	Safety issue
Primary	Changes from baseline in serum or plasma concentration of metabolic, hormonal and inflammatory markers at four other times during pregnancy.	Serum concentration of IGF-1, IGFBP-3, IGFBP-1, FGF-21, Leptin, Adiponectin, CD163, Human Chorionic Gonadotropin, Progesterone, C-peptide, Cortisol, Prolactin, Sex Hormone Binding Globulin, Estradiol, Free fatty acids, Human Placental Lactogen and Human Placental Growth Hormone.; Plasma concentrations of IL-6, IL-10, IL-1alpha, IFN-gamma, TNF-alpha, ICAM1, VCAM, LDL, HDL, Triglyceride, Gamma-Glutamyl Transferase, Thyrotropin, glucose and HbA1c.	Gestational week 8-10 (baseline), gestational week 10-14, gestational week 18-22, gestational week 24-28 and gestational week 34-38
Primary	Assocation between the serum or plasma concentration of metabolic, hormonal and inflammatory markers Versus Insulin sensitivity at five times during pregnancy.	Association between the metabolic, hormonal and inflammatory markers listed as Primary Outcome 1 and the Insulin sensitivity. Insulin sensitivity will be estimated using the homeostasis model assessment (HOMA-IR) based on fasting insulin and glucose concentrations.	Gestational week 8-10, gestational week 10-14, gestational week 18-22, gestational week 24-28 and gestational week 34-38
Primary	Changes from baseline in the level, content and bioactivity of exosomes in serum and plasma at four other times during pregnancy.	Exosomes will be isolated and profiling of the content will be performed using SWATH mass spectrometry and miRNA sequencing.	Gestational week 8-10 (baseline), gestational week 10-14, gestational week 18-22, gestational week 24-28 and gestational week 34-38
