Highlights

• Low serum concentrations of CYP27A1 in AD, PD and MSA patients.
• Low serum concentrations of CYP27B1 in MSA patients.
• Serum P450 concentrations affect VD metabolites in neurodegenerative disorders.

Introduction
We previously reported lower serum 25-hydroxyvitamin D concentrations in patients with Alzheimer’s disease (AD), Parkinson’s disease (PD) and Multiple system atrophy (MSA) compared to healthy controls (HC), whereas 1,25-di-hydroxyvitamin D levels were solely lower in MSA patients. We investigate serum concentrations of P450 involved in Vitamin D(VD) hydroxylation to clarify the responsible hydroxylase for the low serum concentrations of VD metabolites.

Methods
A total of 79 individuals were enrolled including 20 HC, 20 AD, 19 PD and 20 MSA patients. The serum concentrations of P450 involved in VD hydroxylation were assayed by ELISA. The data were analyzed by the nonparametric Kruskal-Wallis test between groups.

Results
Though CYP2R1 and CYP27A1 mediate 25-hydroxylation for VD, CYP2R1 is the main hydroxylase, and CYP27A1 is also involved in VD synthesis. CYP2R1 concentrations showed no differences among groups, while lower CYP27A1 concentrations were found in PD (p < 0.05) and MSA (p < 0.005) compared to HC and differences between AD and MSA (p < 0.05), however no differences between PD and MSA. CYP27B1 is the main 1α-hydroxylase for 25-hydroxyvitamin D and showed differences between HC and PD (p < 0.05), between HC and MSA (p < 0.005) and between PD and MSA (p = 0.055). CYP24A1, which inactivate 1,25-di-hydroxyvitamin D, showed no differences among groups.

Conclusions
CYP27A1 might affect VD synthesis and cause low 25-hydroxyvitamin D levels in AD, PD and MSA patients. Low 1,25-di-hydroxyvitamin D levels in MSA patients might be caused by impaired feedback mediated by CYP27B1.

VitaminDWik - CYP27B1 category contains

The CYP27B1 gene activates Vitamin D in the Kidney,    Skin,    Lungs,    Brain,   Eyes   Breasts   etc.
Poor CYP27B1 is assocated with COVID, Miscarriage,   Lupus,   Alz, Parkinson, MSA,   Rickets

CYtochrome P450 family 27 subfamily B member 1    = 25-Hydroxyvitamin D3 1-alpha-hydroxylase

• 63 items in CYP27B1 category
• 343 articles in the Genetics
• 530 articles in Vitamin D Receptor
• 178 articles in Vitamin D Binding Protein
• CYP27B1 and other genes are less activated in seniors
• CYP27B causes many health problems – March 2020
• Every Parkinson’s brain had a poor CYP27B1 gene

What can be done if have a poor CYP27B1

• Larger doses of Vitamin D
• More Bio-available: Gut-friendly form, Topical form, taken with fatty meal, taken with evening meal
• Additional sources: UV
• Increase Vitamin D metabolism: additional Magnesium, Omega-3
  • All cytochrome P450 enzymes require Mg++ as a cofactor
• Increase the amount of Vitamin D in the blood that gets to cells: increase activation of VDR
  • See: Reasons for low response to vitamin D

Vitamin D blood test misses a lot

• Vitamin D from coming from tissues (vs blood) was speculated to be 50% in 2014, and by 2017 was speculated to be 90%
• Note: Good blood test results (> 40 ng) does not mean that a good amount of Vitamin D actually gets to cells
• A Vitamin D test in cells rather than blood was feasible (2017 personal communication)   Commercially available 2019
  • However, test results would vary in each tissue due to multiple genes
• Good clues that Vitamin D is being restricted from getting to the cells
  1) A vitamin D-related health problem runs in the family
      especially if it is one of 51+ diseases related to Vitamin D Receptor
  2) Slightly increasing Vitamin D shows benefits (even if conventional Vitamin D test shows an increase)
  3) DNA and VDR tests - 100 to 200 dollars $100 to $250
  4) PTH bottoms out ( shows that parathyroid cells are getting Vitamin d)
     Genes are good, have enough Magnesium, etc.
  5) Back Pain
     probably want at least 2 clues before taking adding vitamin D, Omega-3, Magnesium, Resveratrol, etc

VitaminDWiki - Overview Alzheimer's-Cognition and Vitamin D contains

• FACT: Cognitive decline is 19X more likely if low vitamin D
• FACT: Dementia is associated with low vitamin D levels.
• FACT: Alzheimer’s Dementia 2.3X more likely in elderly if low vitamin D – Dec 2022
• FACT: Dementia is associated with low vitamin D - many studies
• FACT: Alzheimer's Disease is 4X less likely if high vitamin D
• FACT: Every single risk factor listed for Alzheimer's Disease is also a risk factor for low vitamin D levels
• FACT: Elderly cognition gets worse as the elderly vitamin D levels get even lower (while in senior homes)
• OBSERVATION: Reports of increased vitamin D levels result in improved cognition
• OBSERVATION: Alzheimer’s patients 3X more likely to have a malfunctioning vitamin D receptor gene – 2012
