Brief Summary

Effect of L-carnitine supplementation on phenylalanine and brain-derived neurotrophic factor levels in infants and children with phenylketonuria L-carnitine is mainly obtained from foods such as red meat and milk that are limited for PKU patients due to dietary protein restriction. So, L-carnitine deficiency has been described in phenylketonuric patients The aim of this study is to :

  1. 1.Compare level of Brain-derived neurotrophic factor in infants and children with phenylketonuria and healthy infants and children.
  2. 2.Compare level of phenylalanine and Brain-derived neurotrophic factor before and after L-carnitine supplementation in phenylketonuric patients.
  3. 3.Assess Intelligence quotient test before and after L-carnitine supplementation in phenylketonuric patients

Outcome Measures

Primary Outcomes (1)

  • improve brain-derived neurotrophic factor levels

    1 year

Study Arms (2)

88 patients diagnosed as case of phenylketonuria

EXPERIMENTAL
Drug: L-carnitine

88 control healthy children same age and sex

NO INTERVENTION

Interventions

44 patients diagnosed as a case of phenylketonuria will receive l-carnitine at a dose of 100 mg/kg/day for 1 year and then blood sample will examined for level of brain-derived neurotrophic factor levels before and after therapy and another group composed of 44 patients diagnosed as a case of phenylketonuria will not receive l-carnitine and their blood sample will examined for level of brain-derived neurotrophic factor levels treated and untreated patients will compared with healthy children and infants has same age and sex .

88 patients diagnosed as case of phenylketonuria
