Clinical Trial Summary

Prolactin (PRL) and PRL receptor (PRLR) signaling has been validated to play an important role in the modulation of glucolipid metabolism. However, the role of serum PRL levels in gestational diabetes mellitus (GDM) remains unclear. The investigators aimed to explore the possible influence of serum PRL within or without normal range on the development of GDM.

Outcome

Type Measure Description Time frame Safety issue
Primary Gestational diabetes mellitus (GDM) GDM is defined as a glucose intolerance resulting in hyperglycaemia of variable severity with onset during pregnancy. It can be diagnosed by the criteria: a fasting plasma glucose (FPG) concentration of O126 mg/dl on two separate occasions or a random blood glucose concentration of O200 mg/dl on two separate occasions. 2019-2023
Primary PRL serum prolactin level 2019-2023
Secondary Insulin resistance (IR) It was considered to be IR if HOMA-IR >2.5 2019-2023
Secondary HOMA-IR It was calculated as: fasting plasma glucose (FPG) x fasting insulin (FINS)/22.5 2019-2023
Secondary OGTT OGTT was performed after an overnight fasting in each patient and blood samples were taken at 0, 30, 60, 120, and 180 min to determine the concentrations of plasma glucose. 2019-2023
