Management of diabetic pregnancy complicated by coronary artery disease and neuropathy

Various manifestations of diabetic neuropathy may complicate pregnancies of young diabetic patients. Of all forms of diabetic neuropathy, autonomic neuropathy, and, in particular, gastropathy, may cause the most devastating complications. Because neuropathy is a common abnormality in young asymptomatic diabetic women, screening for this disorder may be advisable and can be accomplished by relatively simple and noninvasive tests. Screening is best performed before conception or early in pregnancy, because pregnancy itself and its possible complications later modify the autonomic nervous function tests and make testing unreliable. Practitioners and obstetricians who provide care and counseling to young diabetic patients should be familiar with the risks and consequences to maternal and fetal health that may be imposed by the different forms of neuropathy. Moderate-to-severe autonomic dysfunction may be considered a relative contraindication to pregnancy, especially if gastropathy is part of the clinical presentation. The management dilemmas and high mortality and morbidity associated with symptomatic diabetic neuropathy may justify the addition of a new independent class, class N (neuropathy), to the current classification systems for diabetes in pregnancy.
