Phenylketonurias Clinical Trial
— PCUOfficial title:
Becoming Adulthood of Phenylketonuric Patients Screened in the Neonatal Period: From 1971 to the Present Day.
You were detected during the neonatal period for phenylketonuria and you benefited from the diagnosis of an adapted dietetic care, and this for a variable duration according to the recommendations followed at that time. The recommendations for the management of phenylketonuria have evolved considerably over time, lengthening the duration, rigor of the diet and target rates. However, few studies have been able to determinate the influence of metabolic balance and pediatric management on fate in adulthood. As you know, the current recommendations are more stringent and prolonged, without taking into account the pediatric data of today's adult patients. The objective of this study, which is aimed at all adult patients screened and followed by Lille University Hospital, according to the same care methods, allowing a homogeneous monitoring of patients, is to assess the influence of pediatric care (duration of the diet, metabolic balance, compliance) on the future in adulthood. This retrospective and current analysis work could help refine the current recommendations.

Primary | Adult intelligence quotient (IQ) score | Adult intelligence quotient (IQ) score assessed at the last setback in the two groups defined by the duration of the hypoprotidic diet during childhood | Baseline | |
Secondary | The IQ score in adulthood assessed defined by the target Phenylalanine level in one subgroup treated during 8 years. | The IQ score in adulthood assessed at the last time of decline according to the two subgroups treated during 8 years, defined by the target Phenylalanine level ((2-5 mg/dl versus 8-12 mg/dl) | Baseline, at the last time of decline (= 8 years of low-protein diet) | |
Secondary | The IQ score in adulthood assessed according to the length of expanding the Diet (Phe intake) during childhood for children treated during 10 years (target Phe level 2-5 mg/dl) | The IQ score in adulthood assessed according to length (and degree) of expanding the Diet (increasing Phe intake, during 6 months whatever the Phe levels or longer according the Phe levels) during childhood for children treated during 10 years (xith target Phe level 2-5 mg/dl) | Baseline,at the last time of decline (= 10 years of low-protein diet) | |
Secondary | The IQ score in adulthood assessed defined by the metabolic biological parameters in childhood | The IQ score in adulthood assessed at the last time of decline according to the metabolic parameters during childhood | Baseline | |
Secondary | The IQ score in adulthood assessed according to the first phenylalanine level in the target (< 5 mg/dl) | The IQ score in adulthood assessed according to the first phenylalanine level in the target (< 5 mg/dl) in the neonatal period | baseline |
