In order to test the hypothesis that adrenocortical overactivity, possibly related to the stress of testing, may impact on the measurement of circulating androgen concentrations during glucose-induced hyperinsulinaemia, we prospectively screened 10 patients with the polycystic ovary syndrome (PCOS) and nine healthy control women with an oral glucose tolerance test (OGTT), before and after the a...

BACKGROUND A highly standardized screening test for newly diagnosis diabetes and pre-diabetes is necessary. the study goal was to clarify the power and efficacy of glycated hemoglobin (HbA1c) in the diagnosis of diabetes and pre-diabetes by comparing against the other American Diabetes Association (ADA) diagnostic criteria of fasting plasma glucose (FPG) and oral glucose tolerance test (OGTT). ...

Methods We compared Caucasian women with previous GDM (n=116), and with normal glucose tolerance (NGT) during pregnancy (n=52), using a 75g OGTT, to determine prevalence of diabetes/pre-diabetes 1-5 years post index pregnancy. Women with abnormal OGTT 12 weeks post-partum (n=22: IFG/IGT, n=20, DM, n=2) did not undergo OGTT, but were included in the analysis. American Diabetes Association diagno...

Aim: The goal of this study was to establish the level awareness amongst pregnant women in terms preparation for an oral glucose tolerance test (oGTT), compare results two waves data collection, and identify most frequent preanalytical mistakes made connection oGTT. Design: Comparison 2 cross-sectional studies. Methods: From 2013–2017 independent questionnaire studies were performed on a ...

OBJECTIVE Gestational impaired glucose tolerance (GIGT), defined by a single abnormal value on antepartum 3-h oral glucose tolerance test (OGTT), is a metabolically heterogeneous disorder. Indeed, the antepartum metabolic phenotype of women with a single abnormal value at 1 h during the OGTT (1-h GIGT) resembles that of women with gestational diabetes mellitus (GDM), whereas GIGT at 2 or 3 h (2...

Twenty-four middle-aged healthy men were given a low-fat high-carbohydrate (5.5 g fat; L), or a moderately-fatty, (25.7 g fat; M) breakfast of similar energy contents for 28 d. Other meals were under less control. An oral glucose tolerance test (OGTT) was given at 09.00 hours on day 1 before treatment allocation and at 13.30 hours on day 29. There were no significant treatment differences in fa...

Oral glucose tolerance test (OGTT) is usually insufficient to accurately predict the risk for type 2 diabetes mellitus (T2DM), it is therefore necessary to identify an additional biomarker that would most likely improve the accuracy of OGTT. The current OGTT was performed in 53 volunteers after ingestion of 75 g glucose in 250 ml water to each volunteer. Similarly the sphingoid base profile of ...

INTRODUCTION Women with history of gestational diabetes mellitus (GDM) have up to 50% lifetime risk of developing frank diabetes mellitus (DM). They are an ideal group of patients to implement early interventional measures to halt the progression to diabetes. The success of any early intervention programme would depend largely on postpartum follow-up. We set out to study the response rate to po...

In the diagnosis of diabetes mellitus, hemoglobin A1c (HbA1c) is sometimes measured to determine the need of an oral glucose tolerance test (OGTT). However, HbA1c does not accurately reflect glycemic status in certain conditions. This study was performed to test the possibility that measurement of serum glycated albumin (GA) better assesses the need for OGTT. From 2006 to 2012, 1559 subjects no...
