Correlation of serum vitamin A and its transport protein (RBP) in malnourished and vitamin A deficient children.
Eighty nine children were studied for retinol (vitamin A) estimation and its transport protein--retinol-Binding Protein (RBP). Serum levels of retinol, RBP and serum protein and albumin were found to be low in children with signs of vit. A deficiency irrespective of their nutritional status. Serum levels of retinol and RBP were risen significantly almost double, after the oral and parenteral administration of vitamin A. PEM interferes with hepatic synthesis of RBP and the release of RBP from the liver depends on vitamin A. Vitamin A is a limiting factor, the presence of which is required for the release of apo-RBP from the liver.
