GLP-1 Response in Women With PCOS and Prediabetes

Study Overview
=================
Brief Summary
-----------------
Women with PCOS are more prone to obesity which exacerbates insulin resistance, the abdominal fat disposition and metabolic risk of these patients. With development of obesity these women have high conversion rate from normal glucose tolerance to impaired glucose tolerance and in turn to type 2 diabetes. Glucagon-like peptide 1 (GLP-1) is involved in body weight maintenance. Beside energy balance it is also involved in glucose homeostasis. Functional deficit in GLP-1 facilitates obesity. We investigated the link between the concentration of incretin hormones and glucose homeostasis, metabolic complications and the distribution of body composition in obese women with PCOS.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: NGT<br>NGT - normal glucose tolerance. Women with PCOS and normal glucose tolerance | Diagnostic Test: oral glucose tolerance test<br>* GLP1 response to oral glucose load during oral glucose tolerance test was assessed.<br>|
| Active Comparator: IGH<br>IGH - impaired glucose homeostasis Women with PCOS and impaired glucose homeostasis - that means impaired fasting glucose or impaired glucose tolerance. | Diagnostic Test: oral glucose tolerance test<br>* GLP1 response to oral glucose load during oral glucose tolerance test was assessed.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The main outcome was difference in fasting and after load GLP1 levels between two groups | Patient GLP1 levels were measured at base point and in 120 min of 75-g OGTT. GLP1 levels were compared between groups | 3h | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The secondary outcome was to evaluate the between group difference in beta cell function, and visceral adipose tissue. | At base point visceral adipose tissue (VAT) mass, volume and area were measured with DXA. To assess beta cell function static and dynamic parameters of beta cell function were calculated. | 3h |
