Nutrient management in the intrapartum period in maternal maple syrup urine disease.

ABSTRACT: Women with congenital amino acid disorders, including maple syrup urine disease (MSUD), are at risk of metabolic crisis at delivery. There are still only a few case reports of maternal MSUD globally, and we are the first to report the successful perinatal management of a woman with classical MSUD in Japan. A healthy baby was delivered by scheduled cesarean section despite the presence of several uterine fibroids. With precise diet therapy and accurate preparation, she completed the postpartum period without metabolic decompensation. Although her clinical outcome was favorable, she experienced hypoproteinemia at delivery because the available branched-chain amino acid-free medical food did not contain sufficient protein to meet the recommended nutrient intake. Therefore, this case also indicates a potential issue regarding a shortage of variations in specific amino acid-free medical food in Japan, which should be addressed to achieve a better nutrient status of adults with MSUD and other amino acid disorders.
