Present and future perspectives on the use of free or encapsulated pancreatic islet cell transplantation as a treatment of pregnancy complicated by type 1 diabetes.
Pregnancies complicated by insulin-dependent diabetes mellitus (IDDM) pose significant health risks to both the mother and her developing fetus. Congenital malformations in the offspring of diabetic mothers have an incidence which is 2-5 times that seen in the background. Euglycemia in the first trimester of pregnancy can reduce this incidence, but achieving euglycemia with conventional exogenous insulin therapy is both costly and difficult. Even with intense insulin dosage adjustments, the blood glucose profile of the diabetic pregnant patient does not mimic that seen in nondiabetic patients. Both the difficulties and inadequacies of conventional therapy for IDDM-complicated pregnancy provide a stimulus for research to develop improved therapeutic modalities. Islet transplantation holds great promise as a treatment for pregnancies complicated by IDDM. This article reviews the current status of islet transplantation including the use of immunomodulation and immunoisolation techniques and their potential use for the treatment of IDDM pregnancies.
