The Effect of Continuous Glucose Monitoring System on Severe Complications to Pregnancy in Women With Diabetes

2014-08-27 03:18:41 | BioPortfolio


The purpose of the study is to investigate the effects of Continuous Glucose Monitoring System on severe complications to pregnancy in women with diabetes.


Pregnancy outcome in women with type 1 or type 2 diabetes is still significantly poorer than in the background population. The prevalence of large fat babies (LGA) is 50% in both types of diabetes, and perinatal death and preterm delivery is 4-7 times higher than in non-diabetic women. These complications are all closely related to non-optimal glycemic control in pregnancy, and improved metabolic control is crucial in our strive for improved pregnancy outcome in these patients.

In 2007, a new generation of real time Continuous Glucose Monitoring Systems (CGMS) became available in Denmark. These sensors estimate tissue glucose values automatically and frequently with immediate display of the glucose level. In addition it is possible to set alarms for high and low glucose levels, and the patient can react immediately with changes in diet or insulin dose.

In this trial, approximately 170 patients are randomized to either continuous glucose monitoring at five times in pregnancy in addition to standard care ot to unchanged standard care. The main aim is to evaluate if the use of CGMS in pregnancy can reduce the prevalence of LGA from 50 to 30%, but other outcome measurements such as preterm delivery, neonatal disease, hypoglycemia, low grade inflammation and vascular dysfunction, quality of life and self- care are also recorded.

Medical and Biotech [MESH] Definitions

The state of PREGNANCY in women with DIABETES MELLITUS. This does not include either symptomatic diabetes or GLUCOSE INTOLERANCE induced by pregnancy (DIABETES, GESTATIONAL) which resolves at the end of pregnancy.

Diabetes mellitus induced by PREGNANCY but resolved at the end of pregnancy. It does not include previously diagnosed diabetics who become pregnant (PREGNANCY IN DIABETICS). Gestational diabetes usually develops in late pregnancy when insulin antagonistic hormones peaks leading to INSULIN RESISTANCE; GLUCOSE INTOLERANCE; and HYPERGLYCEMIA.

A condition of fetal overgrowth leading to a large-for-gestational-age FETUS. It is defined as BIRTH WEIGHT greater than 4,000 grams or above the 90th percentile for population and sex-specific growth curves. It is commonly seen in GESTATIONAL DIABETES; PROLONGED PREGNANCY; and pregnancies complicated by pre-existing diabetes mellitus.

Proteins produced by organs of the mother or the PLACENTA during PREGNANCY. These proteins may be pregnancy-specific (present only during pregnancy) or pregnancy-associated (present during pregnancy or under other conditions such as hormone therapy or certain malignancies.)

Urination of a large volume of urine with an increase in urinary frequency, commonly seen in diabetes (DIABETES MELLITUS; DIABETES INSIPIDUS).
