Early metabolic defects following gestational diabetes in three ethnic groups of anti-GAD antibodies negative women with normal fasting glucose.

Objective: To characterise early metabolic abnormalities and the impact of ethnicity following gestational diabetes mellitus (GDM).

Design: Women with a history of GDM belonging to three different ethnic groups were evaluated. Using the insulin-modified, frequently-sampled intravenous glucose tolerance test (FSIVGTT) and HOMA we studied 34 European, 16 South Asian and 10 Afro-Caribbean women with normal fasting glucose following GDM and 44 European, 16 South Asian and 19 Afro-Caribbean controls to assess insulin action and secretion.

Insulin resistance and beta-cell dysfunction in normoglycaemic European women with a history of gestational diabetes.

Objective: Women with previous gestational diabetes (GDM) are at increased risk of subsequent type 2 diabetes. To characterize early metabolic abnormalities associated with this increased risk, we studied normoglycaemic women with a history of GDM.

Patients And Measurements: We performed an insulin-modified, frequently sampled intravenous glucose tolerance test (FSIVGTT) in 34 normoglycaemic European women with previous GDM and 44 European control women, deriving measures of insulin sensitivity, glucose effectiveness, glucose disappearance rate and acute insulin response to glucose.

Delayed metabolic and thermogenic response to a mixed meal in normoglycemic European women with previous gestational diabetes.

We assessed postprandial thermogenesis (PPT) for 3 h following a mixed meal in 29 normoglycemic European women with previous gestational diabetes (GDM), compared with 37 control women. Given the potential role of catecholamines and insulin in the regulation of PPT, we assessed insulin and catecholamine responses to the meal. There was no significant difference between the two groups in resting energy expenditure, PPT (although lower in the GDM group), or catecholamine levels.

Elevation of soluble E-selectin levels following gestational diabetes is restricted to women with persistent abnormalities of glucose regulation.

Objective: Increased levels of the soluble adhesion molecule sE-selectin have been reported in normoglycaemic women with previous gestational diabetes but not in other groups at increased risk of future type 2 diabetes. To explore the basis for these discrepant findings, we studied the relationship between sE-selectin and glucose regulation in a large group of women with previous gestational diabetes.

Design: Comparison of sE-selectin levels between a study cohort ascertained on the basis of recent gestational diabetes and suitable control subjects.
