Vitamin D deficiency rickets due to inappropriate feeding: Report of one case

Vitamin D deficiency rickets is rare among infants and children in the industrialized countries. In this paper, we report a 2-year-5-month-old girl with aching and bowed legs. A food allergy with atopic dermatitis was diagnosed since her early infancy. Strict dietary restrictions were done and she was mostly fed soybean juice and rice foods. Fortified soybean formula (Isomil®) was introduced one month before admission. Vitamin D deficiency rickets was diagnosed by a history of inappropriate feeding, roentgenographic and laboratory findings. The therapeutic regimen included I, 25- dihydroxycholecalciferol 0.5μg/day and calcium carbonate 100mg/kg/day. Extensive nutritional counseling was also given for correction of aberrant dietary practices. After a one-year follow-up, there was radiological evidence of bone healing, and marked improvement of leg deformities.
