Serum zinc levels in celiac disease.

This study was done to determine the zinc levels in 30 children with celiac disease. Serum zinc level was estimated at inclusion and zinc supplementation was given for 3 months. Zinc levels were repeated at 3 and 6 months after inclusion. The serum zinc levels of newly diagnosed CD cases (0.64+/-0.34 microg/mL) versus controls (0.94+/-0.14 microg/mL) were significantly lower (95% CI -0.44 to -1.4), whereas in the old cases this difference was non-significant. The serum zinc level among severely malnourished and stunted celiac cases was also significantly lower irrespective of their treatment status. We conclude that serum zinc levels are low in newly diagnosed and severely malnourished children with celiac disease.
