Diabetes-induced birth defects: what do we know? What can we do?

Area of Science:

• Reproductive biology
• Developmental biology
• Endocrinology

Background:

• Birth defects are a leading cause of infant mortality in the US.
• Pregestational diabetes mellitus (PGDM) in mothers significantly elevates the risk of major birth defects.
• Current interventions like glucose control and supplementation are limited by unplanned pregnancies.

Purpose of the Study:

• To address the urgent need for novel interventions against diabetic embryopathy.
• To develop targeted molecular strategies to reduce birth defects associated with maternal diabetes.

Main Methods:

• Investigating the molecular pathophysiology of diabetic embryopathy.
• Identifying and developing interventions against key molecular targets.

Main Results:

• Experimental and epidemiologic studies show benefits of strict glucose control, multivitamins, fatty acids, and low-glycemic diets.
• These methods are not universally applicable due to high rates of unplanned pregnancies.

Conclusions:

• Diabetic embryopathy is a multifactorial condition requiring new therapeutic approaches.
• Targeting specific molecular pathways holds promise for preventing birth defects in pregnancies affected by diabetes.
