Incidental finding of vitamin-D deficient rickets in an otherwise healthy infant--a reappraisal of current vitamin-D supplementation guidelines.
In an effort to prevent rickets and vitamin-D deficiency in healthy infants, the American Academy of Pediatrics recommends a supplement of 200 IU per day of vitamin D to all breastfed and nonbreastfed infants unless they consume at least 500 ml per day of vitamin-D-fortified formula or milk. Case reports of infantile vitamin-D-deficient rickets secondary to maternal vitamin-D deficiency have been reported but focused on mothers who had predictable risk factors for such a deficiency. We report on an infant with vitamin-D-deficient rickets who did not have nutritional risk factors and whose mother did not have nutritional or medical risk factors for such a deficiency. We conclude that the current vitamin-D supplementation guidelines be extended to all infants, regardless of feeding volume or source, or at least to all infants born to dark-skinned mothers.
