The reason we are doing this study is to look at "lipoproteins" in blood vessel disease. Lipoproteins are small units in the blood that carry fats (like cholesterol) in the body: there are different kinds and they are often called "good" and "bad" cholesterol. One way lipoproteins and blood vessel disease may be linked is that lipoproteins may be hurt when they are in contact with high blood sugar (as in diabetes) for a long time. They are toxic to the cells in blood vessel walls. To see if what we think is true, we will get blood from a group of people, we will separate the lipoproteins, then mix everyone's together to look at it. These lipoproteins will be treated like they would be in a person with diabetes.
Pre-eclampsia (PE) happens in pregnancy. It features new onset high blood pressure. It is a major cause of problems to the mother and unborn child. It can lead to health problems in mother and child in the future, which causes a public health problem. We do not know everything about it, but we think it starts in the placenta (the organ that nourishes the unborn child). At this time, we do not know who will get PE. We want to study the placenta, to learn more about the disease.
