Children with low vitamin D3 levels were commenced on cholecalciferol, 2000 IU/day. Their 25(OH)D3 and iPTH levels were reassessed, first after 3 months, and then after 6 months. Data analysis was performed using the Statistical Package for Social Sciences. Paired t-test was used to compare results before and after treatment.RESULTS: Forty-five children (31 boys and 14 girls) were included in the study. Their mean{\textpm}SD age was 9.6 {\textpm} 4.6 years. There was significant improvement in 25(OH)D3 after 3 months (14.2 {\textpm} 8.2 - 20 {\textpm} 11.1 ng/mL) (p\<0.001). However, only 5 children reached levels \>/=30 ng/mL. There was no further improvement after 6 months of treatment (20.17 {\textpm} 13.4 ng/mL) (p=0.65). There was no improvement in iPTH levels after 3 and 6 months. No changes were also observed in the levels of calcium, phosphate, alkaline phosphatase, or creatinine.CONCLUSION: The administration of oral vitamin D3 at 2000 IU/day resulted in significant improvement of vitamin D levels in children with CKD, but normalized only in 11\% of the patients. The treatment had no effect on iPTH levels.}, issn = {0379-5284}, URL = {https://smj.org.sa/content/33/7/740}, eprint = {https://smj.org.sa/content/33/7/740.full.pdf}, journal = {Saudi Medical Journal} }
