Children under continuous kidney replacement therapy have higher risk of vitamin D deficiency, finds research

In this prospective observational research conducted at a single site, the study included 37 patients who needed regional citrate anticoagulation and CKRT for at least 28 days. The duration of CKRT was the exposure, and the results included osteopenia and/or fractures, as well as 25-hydroxy vitamin D. Vitamin D insufficiency and deficiency were prevalent in 17.2% and 69.0% of people, respectively. The radiographic evidence of osteopenia and/or fractures were present in 29.7% of the patients. Also, age or ethnicity did not appear to have any impact on vitamin D deficit or insufficiency. Vitamin D levels were not predicted by duration on CKRT or intact PTH levels. After correcting for age and length of CKRT, children with chronic liver illness had an odds ratio higher than children with other main diagnoses for osteopenia and/or fractures.

Overall, vitamin D insufficiency and inadequacy are common in juvenile AKD patients undergoing CKRT and may deteriorate despite conventional supplementation. The patients who require extended CKRT may require higher doses of vitamin D supplementation to maintain adequate levels and avoid MBD.
