Studies on the effects of gluten-free diet (GFD) on bone mineral metabolism have given no univocal results in children and adults with celiac disease. Bone mineral metabolism was assessed in 23 celiac children, aged 1 to 12 years (mean 4.6) at moment of diagnosis (T 0 ) and after 12 months of GFD (T 1 2 ) without any vitamin D supplementation. At T 0 , calcium, phosphates and alkaline phosphatase values were within the normal range in all but few subjects, but their respective average values significantly rose at T 1 2 . The percentages of low values of bone mineral density and of osteocalcin at T 0 were significantly higher than those at T 1 2 and their respective average values significantly increased between T 0 and T 1 2 . Circulating parathyroid hormone values were within the normal range in all patients at T 0 and T 1 2 , with no significant difference in average values between T 0 and T 1 2 . One year of GFD is sufficient to obtain a complete restoration of bone mineral density even without vitamin D supplementation. The normal levels of parathyroid hormone and the reduced osteocalcin at diagnosis suggest that in young celiac children there is no important rise in bone remodeling.
