Further study details as provided by Universita di Verona:

Primary Outcome Measures:
  • We evaluated membrane protein oxidative damage of red cells [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • we evaluated cation transport pathways of red cells [ Time Frame: 6 months ]

Enrollment: 31
Study Start Date: April 2004
Study Completion Date: March 2006
Intervention Details:
    Dietary Supplement: 5-methyltetrahydrofolate and vitamin B12
    children with cystic fibrosis were supplementated for 6 months with 5-MTHF, 7,5 mg/day ; vitamin B12, 0,5 mg/day
Detailed Description:
Cystic fibrosis (CF) is one of the most common fatal autosomal recessive disorders in the Caucasian population caused by mutations of gene for the cystic fibrosis transmembrane conductance regulator (CFTR). New experimental therapeutic strategies for CF propose a diet supplementation to affect the plasma membrane fluidity and to modulate the cellular amplified inflammatory response in CF target organs. Red blood cells (RBCs) were used to investigate plasma membrane, because RBCs share lipid, protein composition and organization with other cell types.
