Objectives: Growing evidence demonstrated that vitamin D levels had been linked to type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) in light of various extraskeletal effects. Therefore, the present study aimed to evaluate the association of 25-hydroxyvitamin D [25(OH)D] level with the clinicopathological features and CKD progression in T2DM.

Methods: A total of 182 patients with T2DM with CKD stages 1 through 4 (G1–G4) were retrospectively included. Identification of the serum 25(OH)D level associated with CKD progression was executed by Kaplan–Meier survival analysis and Cox proportional hazards models. We further performed sensitivity analyses with a time-weighted average (TWA) of the serum 25(OH)D level in 75 participants to reinforce the findings.

Results: The median serum 25(OH)D level was 26 (IQR, 14; 39) nmol/L in the study participants. Median follow-up time was 42 months, during which 70 (38%) patients confronted CKD progression. Cumulative kidney outcomes were significantly higher in the lowest tertile of the serum 25(OH)D level in Kaplan–Meier analyses (P < 0.001). Consistently, the analyses of Cox proportional hazards regression models indicated a significantly greater risk for CKD progression in the lowest tertile of the serum 25(OH)D level compared with the highest tertile of the serum 25(OH)D level (P = 0.03). These relationships remained robust with further sensitivity analysis of data with TWA of the serum 25(OH)D level, showing an independent association between lower TWA of the serum 25(OH)D level and an unfavorable renal outcome in patients with T2DM with CKD.

Conclusions: Our findings demonstrated that patients with T2DM with a decreased 25(OH)D level had deteriorated renal function. Both lower levels of baseline and TWA of serum 25(OH)D were associated with an increased risk of CKD progression in patients with T2DM, which suggested that the long-term maintenance of optimal vitamin D levels from early in life might be associated with reduced future risk of CKD development in T2DM.

VitaminDWiki - Overview Kidney and vitamin D contains

• 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

VitaminDWiki -Overview Diabetes and vitamin D contains

• Diabetes is 5X more frequent far from the equator
• Children getting 2,000 IU of vitamin D are 8X less likely to get Type 1 diabetes
• Obese people get less sun / Vitamin D - and also vitamin D gets lost in fat
• Sedentary people get less sun / Vitamin D
• Worldwide Diabetes increase has been concurrent with vitamin D decrease and air conditioning
• Elderly get 4X less vitamin D from the same amount of sun
      Elderly also spend less time outdoors and have more clothes on
• All items in category Diabetes and Vitamin D 553 items: both Type 1 and Type 2

Vitamin D appears to both prevent and treat diabetes

• Appears that >2,000 IU will Prevent
• Appears that >4,000 IU will Treat , but not cure
• 90% less T2 Diabetes in the group having lots of Vitamin D
• Appears that Magnesium helps both Prevention and Treatment
• Many diabetics would be better treated if Gut-Friendly Vitamin D were used

Diabetic Epidemic

• Step back to 1994. Suppose an epidemic struck the United States, causing blindness, kidney failure, and leg amputations in steadily increasing numbers.
  Suppose that in less than a decade's time, the epidemic had victimized one out of every eight people
  That epidemic is real, and its name is diabetes, now the nation's sixth leading cause of death.
