Kidney Intervention trials using Vitamin D:


Overview Kidney and vitamin D contains the following summary

  • FACT: Kidney is the primary way to activate vitamin D
  • FACT: When the Kidney has problems, there is less active vitamin D (Calcitriol) for the body
  • FACT: When the Kidney has problems, there is increased death due to many factors - many of which are associated with lack of Calcitriol
  • FACT: There are many on-going intervention clinical trials trying to determine how much of what kind of vitamin D is needed to treat the problem
  • FACT: One Randomized Controlled Trial has proven that Vitamin D treats CKD
  • FACT: Taking extra Vitamin D, in various forms, does not cause health problems - even if poor kidney
  • Suggestion: Increase vitamin D getting into body now - and increase co-factors so that the vitamin D can be better used
      Sun, UV lamp, Vitamin D supplement - probably > 5,000 IU,
    Calcitriol - which bypasses the need for the kidney to activate vitamin D
      Problems with Calcitriol however: typically only lasts for a few hours, also, possible complications
        Update: Pre-cursor of active vitamin D made from plants is better than calcitriol – Sept 2012

OBJECTIVES:
The objective of this study was to assess vitamin D status of US non-pregnant adults using a standardised assay across 15 mL/min/1.73 m2 increments of kidney function, report the use of dietary supplements containing vitamin D and assess relationships between vitamin D and markers of bone resorption.

DESIGN: This study is a cross-sectional evaluation.

SETTING: The study is from the US National Health and Nutrition Evaluation Survey in 2001-2012.

PARTICIPANTS: The participants were non-institutionalised, non-pregnant adults, age ≥20 years.

PRIMARY AND SECONDARY OUTCOME MEASURES:
The primary outcome measure was serum 25OHD evaluated using liquid chromatography-tandem mass spectroscopy traceable to international reference standards. Secondary outcome measures were use of dietary supplements containing vitamin D and the serum intact parathyroid hormone and bone-specific alkaline phosphatase in a subset of participants.

RESULTS:
The median 25OHD concentration in 27 543 US non-pregnant adults was 25.7 ng/mL (range, 2.2-150.0 ng/mL). Vitamin D supplements were used by 38.0%; mean (SE)=757 (43) international units/day. The range of 25OHD concentration across groups, stratified by kidney function, was 23.0-28.1 ng/mL. The lowest concentration of 25OHD observed was in people with higher kidney function (23.0 ng/mL for estimated glomerular filtration rate >105 mL/min/1.73 m2). Only 24% of people not taking a dietary supplement had a 25OHD concentration >30 ng/mL. Serum intact parathyroid hormone inversely correlated with 25OHD within all kidney function groups. Bone-specific alkaline phosphatase was also negatively associated with 25OHD concentration.

CONCLUSIONS:
These data indicate that 25OHD concentrations and supplement use may be suboptimal in a significant proportion of the population, across all kidney function levels. The response of bone resorption markers further suggests that 25OHD levels could be improved. Together, these data support a re-evaluation of the 25OHD concentration associated with health in adults.
