TY - JOUR TI - Can Stoss Therapy Be Used in Children with Vitamin D Deficiency or Insufficiency without Rickets? AB - Objective: Stoss vitamin D treatment has been recommended for its non-skeletal benefits in adults, but there is a lack of data on the optimal dose of vitamin D stoss therapy in children with vitamin D deficiency/insufficiency without rickets. This study aimed to compare efficiency/side effects of two different stoss therapy regimens (10 000 IU/kg and 300 000 IU vitamin D3) administered in children with vitamin D deficiency/insufficiency without rickets.Methods: Sixty-four children who had vitamin D deficiency/insufficiency were studied. A serum 25-hydroxyvitamin-D (25-OH-D) level of 15-20 ng/mL was considered as vitamin D insufficient and <15 ng/mL was considered as vitamin D deficient. The patients were divided into two groups according to the stoss therapy doses they received. Serum calcium, phosphate, alkaline phosphatase, 25-OH-D, parathyroid hormone levels, and spot urine calcium/creatinine ratios before/after treatment were recorded. Wrist radiography and renal ultrasonography were performed.Results: The mean age of the subjects was 10.6±4.4 years. Thirty-two children were treated with a single vitamin D3 dose of 10 000 IU/kg and 32 patients received 300 000 IU. No difference was found in 25-OH-D levels between the two groups at presentation. The mean level of 25-OH-D was higher in the 10 000 IU/kg group at the second week of therapy. There was no difference between the groups at post-treatment weeks 4 and 12. The 25-OH-D was found to be below optimal levels (>=30 ng/mL) in 66.5% and <20 ng/mL in 21.8% of patients at the third month in both groups. None developed hypercalcemia and/or hypercalciuria. Nephrolithiasis was not detected in any patient.Conclusion: This study showed that both doses of stoss therapy used in the treatment of vitamin D insufficiency/deficiency are effective and safe. However, an optimal level of 25-OH-D cannot be maintained for more than three months.
