Overview Kidney and vitamin D contains the following summary

• FACT: The Kidneys are not the primary way to activate vitamin D; the tissues are
• 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 ongoing 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: 38% of seniors have Chronic Kidney Disease and most are unaware of it CDC statistics 2020
• 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,
  Nanoemulstion vitamin D (inside cheek, topically) gets activated Vitamin D to the cells without the need for healthy kidney, liver, or intestine
  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

Background
Vitamin D deficiency is highly prevalent in patients on dialysis. Although vitamin D deficiency is closely associated with cardiovascular disease (CVD) and high mortality in the general population, the relationship between serum 25-hydroxyvitamin D [25(OH)D] and all-cause and cardiovascular mortality in dialysis patients is uncertain. We aim to explore the relationship between serum 25(OH)D levels and all-cause and cardiovascular mortality in dialysis patients.

Methods
This is a systematic review and meta-analysis of clinical studies among patients receiving maintenance dialysis. We did a systematic literature search in PubMed and Embase to identify studies reporting the relationship between serum 25(OH)D levels and all-cause and cardiovascular mortality in patients on dialysis. The search was last updated on 10 February 2017.

Results
The study included 18 moderate to high-quality cohort studies with an overall sample of 14 154 patients on dialysis. The relative risk of all-cause mortality per 10 ng/mL increase in serum 25(OH)D level was 0.78 [95% confidence interval (CI) 0.71–0.86], although there was marked heterogeneity (I2=96%, P < 0.01) that was partly explained by differences in CVD prevalence, baseline parathyroid hormone level and dialysis duration among included studies. The relative risk of cardiovascular mortality per 10 ng/mL increase in serum 25(OH)D level was 0.71 (95% CI 0.63–0.79), with substantial heterogeneity (I2=74%, P=0.004) that was largely explained by differences in study type and serum 25(OH)D measurement method.

Conclusions
In the present study, increased serum 25(OH)D level was significantly associated with lower all-cause mortality and lower cardiovascular mortality in dialysis patients.
