Abstract
Background
We aimed to investigate the effect of single, high-dose intramuscular cholecalciferol on vitamin D3 and intact parathyroid hormone (iPTH) levels in children with chronic kidney disease (CKD).
Methods
Between January 2012 and June 2012, we conducted a prospective, uncontrolled study at the Pediatric Nephrology Unit of King Abdulaziz University Hospital, Jeddah, to investigate the effect of single, high-dose intramuscular vitamin D3 on 25(OH)D3 and iPTH levels in vitamin D insufficient/deficient children with CKD. Serum vitamin D3, iPTH, calcium, phosphate, alkaline phosphatase (ALP), and creatinine levels were measured before intramuscular vitamin D3 (300,000 IU) administration, and these were subsequently repeated at 1 and 3 months after treatment. Statistical analysis was performed with the Statistical Package for the Social Sciences (SPSS Inc., Chicago, IL, USA).
Results
Nineteen children fulfilled the criteria. At 3 months after treatment, vitamin D3 levels were significantly higher than at baseline (p < 0.001) but lower than the levels at 1 month. iPTH levels decreased significantly at 3 months (p = 0.01); however, the drop in iPTH levels was not significant at 1 month (p = 0.447). There were no changes in calcium, phosphate, ALP, or creatinine levels after treatment.
Conclusions
Single-dose intramuscular vitamin D3 (300,000 IU) resulted in significant improvement of vitamin D3 and iPTH levels in children with CKD.
