Plasma glutamine and cystine are decreased and negatively correlated with endomysial antibody in children with celiac disease.

Background And Objectives: Glutamine is a nonessential amino acid which improves intestinal mucosal regeneration and absorption. Glutathione is a vital molecule for antioxidant reactions and is synthesized from cystine. The first aim of the study is to measure the plasma glutamine and cystine in children with celiac disease (CD) and compare them with controls.
