Maternal phenylketonuria (MPKU) requires early dietary control. Achieving blood phenylalanine control before or during pregnancy significantly improves offspring development, highlighting the importance of preconceptional management.

Area of Science:

  • Reproductive Medicine
  • Metabolic Disorders
  • Pediatric Development

Background:

  • Maternal phenylketonuria (MPKU) poses significant risks to offspring development.
  • Hyperphenylalaninaemia (HPA) in pregnant women also requires careful management.
  • Early identification and intervention are crucial for mitigating adverse outcomes.

Purpose of the Study:

  • To identify pregnant women with phenylketonuria (PKU) and mild hyperphenylalaninaemia (HPA).
  • To inform women about the risks associated with untreated PKU/HPA during pregnancy.
  • To assess the effectiveness of phenylalanine-restricted diets on offspring development.

Main Methods:

  • Prospective follow-up of pregnancies in women with PKU and HPA.
  • Monitoring blood phenylalanine (Phe) levels.

  • Evaluating offspring physical growth and cognitive/motor development up to age 2 years.

    • Main Results:

    • 34 live births from 43 followed pregnancies (24 PKU, 10 HPA).
    • Significant negative correlation between gestational age at Phe control and offspring outcomes.
    • Earlier dietary control (Phe < 360 mumol/l) correlated with better growth and development.

    Conclusions:

    • Preconceptional dietary control is strongly recommended to minimize MPKU risks.
    • Timely tracking and information for young women about MPKU risks are vital.
    • Effective management of maternal PKU/HPA improves pregnancy outcomes and child development.
