Brief Summary: Background

The risk of stillbirth and preterm delivery is three times increased among pregnant women with type 1 diabetes compared with healthy pregnant women Normal blood glucose levels are mandatory in order to prevent these complications Severe hypoglycemia requiring assistance from another person is the decisive limiting factor for obtaining near-normal blood glucose regulation in pregnant women with type 1 diabetes Severe hypoglycemia occurs in about one third of pregnancies complicated with type 1 diabetes and can result in unconsciousness traffic accidents and deaths

Aim To test the following hypotheses

1 Severe hypoglycemia is frequent in pregnancy complicated by type 1 diabetes with the highest incidence in gestational weeks 8-16 and the lowest incidence in gestational weeks 28-34
2 Predictors for severe hypoglycemia during pregnancy complicated with type 1 diabetes can be identified at the first pregnancy visit
3 Possible pathophysiological mechanisms include changes in the growth hormone system and in the renin-angiotensin-system during pregnancy

Methodology

One hundred and eight pregnant women with type 1 diabetes are consecutively and prospectively included In connection with the clinical control at the first pregnancy visit at week 9 and in gestational weeks 14 22 28 34 and one day postpartum the following tests are carried out

The patients are asked to answer a validated questionnaire about mild and severe hypoglycemia and hypoglycemia-associated factors such as blood glucose level during hypoglycemia the degree of awareness pregnancy-associated nausea and vomiting insulin type and dose etc Other medication exercise habits coffee- and alcohol intake smoking and social status will be recorded In case of severe hypoglycemia a structured interview concerning the episode will be performed within 24 hours Blood glucose HbA1c the degree of insulin resistance and the levels of IGF1 placenta growth hormone and of the renin-angiotensin-system will be monitored
