• Research summary

  This is an observational study evaluating the use of PKU Sphere in the dietary management of PKU during pregnancy and pre-conception.

  Patients will be aged 16 years onwards and will be recruited during either pre-conception or during their pregnancy. As this can be a stressful time for patients, the majority of data collected during the study will be from assessments, tests, procedures and visits that are standard of care. There will be some additional questionnaires related to their pregnancy and protein substitute intake. Some data will be collected via diaries completed at home but the majority will be collected by the dietitian from telephone consultations, which is standard practice, minimising hospital visits.

  The data collection will include:
  • details of the recommended dietary management plan
  • the patient’s actual intake of PKU Sphere to compare against the recommended amount
  • tolerance / GI symptoms
  • phenylalanine and tyrosine levels
  • plasma amino acid and micronutrient levels
  • 3-day food diary
  • patient acceptability assessment of the product, which may vary during pregnancy

  Phenylalanine and tyrosine monitoring will not be increased compared to standard care.

  There will be very limited, routine outcome data collected about the neonate.
