Successful Pregnancy in a Young Woman with Multiple Acyl-CoA Dehydrogenase Deficiency.

Abstract

Multiple acyl-CoA dehydrogenation deficiency (MADD) is an inborn disorder of fatty acid oxidation due to a defect in electron transfer to the respiratory chain. We describe the medical/nutritional management of a successful pregnancy in a 19-year-old woman with a known diagnosis of MADD. A high-carbohydrate, low-fat, six-meal diet supplemented with protein was prescribed to meet the nutritional needs during pregnancy. L-Carnitine supplementation was also progressively increased over the weeks. Serum acyl-carnitine profile revealed raised levels of chain-length C6-C14, which remained substantially unchanged during pregnancy. Serum amino acid profile was in the normal range indicating an adequate nutritional support. Pregnancy progressed uneventful and the patient gave birth to a healthy boy without any complication.A careful clinical monitoring associated with an adequate medical/nutritional management may improve pregnancy outcome in women with MADD.
