Serum carnitine and selenium levels in children with celiac disease.

ABSTRACT

BACKGROUND AND AIM: Celiac disease (CD) is a gluten-induced enteropathy that results in malabsorption of nutrients. We studied the serum levels of carnitine and selenium in children with CD. METHODS: Serum levels of free carnitine and selenium were studied in 30 children (mean age 8.1 [4.4] years) with CD and 30 age- and gender-matched healthy children. All patients had type 3 duodenal lesions. The mean (SD) serum levels of free carnitine and selenium were lower among patients with CD (24.5 [7.7] micromol/mL and 52.1 (12.9) micromol/mL, respectively) than among healthy controls (29.4 [9.2] and 65.1 [17.2] micromol/mL; p < 0.05 each). Levels were similar in children with and without diarrhea. CONCLUSIONS: Serum carnitine and selenium levels are decreased in children with CD, probably due to malabsorption.
