Note: 29.6% of Mexican TB patients had the poor VDR gene
- Million TB deaths annually, yet proven treatments of Vitamin D, sunshine, etc are not used – July 2017
- Tuberculosis recovery speeded up by single 450,000 IU dose of vitamin D – RCT Jan 2017
- Low vitamin D is a risk factor for tuberculosis – meta-analysis Dec 2016
- Tuberculosis -100 percent cure rate with 10,000 IU of vitamin D daily – RCT 2006
- Tuberculosis, genes and vitamin D – Meta-Analysis Dec 2013
More TB-related genes than just the Vitamin D Receptor
Items in both categories TB and VDR are listed here:
- TB patients had low Vitamin D and poor Vitamin D receptor – June 2019
- TB and Leprosy are easily confused and associated with Vitamin D Receptor
- Certain types of Tuberculosis are 2X more likely with a poor Vitamin D Receptor – April 2019
- Tuberculosis increased risk if poor Vitamin D receptor varies by race – meta-analysis Feb 2019
- Pulmonary Tuberculosis 2X more likely if poor Vitamin D Receptor (Mexico) – April 2018
- TB risk in Blacks increased 20 percent having poor Vitamin D Receptors – Sept 2017
- Tuberculosis 1.3 times more likely if poor Vitamin D Receptor – meta-analysis Oct 2016
- Tuberculosis, genes and vitamin D – Meta-Analysis Dec 2013
Vitamin D Receptor category has the following
Vitamin D tests cannot detect Vitamin D Receptor (VDR) problems
A poor VDR restricts Vitamin D from getting in the cells
It appears that 30% of the population have a poor VDR (40% of the Obese )
Several diseases protect themselves by deactivating the Vitamin D receptor. Example: Breast Cancer
- - - - - - - -
The Vitamin D Receptor is associated with many health problems
Some health problems, such as Breast Cancer, Diabetes, and COVID protect themselves by reducing VDR activation
55 health problems associated with poor VDR
A poor VDR is associated with the risk of 55 health problems click here for details
The risk of 48 diseases at least double with poor VDR as of Jan 2023 click here for details
Some health problem, such as Breast Cancer reduce the VDR
VDR at-home test $29 - results not easily understood in 2016
There are hints that you may have inherited a poor VDR
How to increase VDR activation
Compensate for poor VDR by increasing one or more:
| Increasing | Increases |
| 1) Vitamin D supplement Sun Ultraviolet -B | Vitamin D in the blood and thus in the cells |
| 2) Magnesium | Vitamin D in the blood AND in the cells |
| 3) Omega-3 | Vitamin D in the cells |
| 4) Resveratrol | Vitamin D Receptor |
| 5) Intense exercise | Vitamin D Receptor |
| 6) Get prescription for VDR activator paricalcitol, maxacalcitol? | Vitamin D Receptor |
| 7) Quercetin (flavonoid) | Vitamin D Receptor |
| 8) Zinc is in the VDR | Vitamin D Receptor |
| 9) Boron | Vitamin D Receptor ?, etc |
| 10) Essential oils e.g. ginger, curcumin | Vitamin D Receptor |
| 11) Progesterone | Vitamin D Receptor |
| 12) Infrequent high concentration Vitamin D Increases the concentration gradient | Vitamin D Receptor |
| 13) Sulfroaphane and perhaps sulfur | Vitamin D Receptor |
| 14) Butyrate especially gut | Vitamin D Receptor |
| 15) Berberine | Vitamin D Receptor |
Note: If you are not feeling enough benefit from Vitamin D, you might try increasing VDR activation. You might feel the benefit within days of adding one or more of the above
Far healthier and stronger at age 72 due to supplements Includes 6 supplements that help the VDR
Increased risk of diseases if poor VDR
Increased risk associated with a poor Vitamin D Receptor
Note: Some diseases reduce VDR activation
those with a * are known to decrease activation
Highlights
• Genetic variations are relevant in modulating susceptibility to PTB.
• We studied the association between polymorphic VDR and PTB in a Mexican population.
• The CC genotype of FokI increased susceptibility to PTB.
Background and Aims
The impact of host genetic variation in susceptibility of tuberculosis is well documented. The Vitamin D receptor gene (VDR) is a transacting transcription factor which mediates innate immune response by enhancing the expression of several antimicrobial peptides, including cathelicidin. An association between VDR polymorphisms with tuberculosis (TB) has been investigated in different ethnic groups; however there are contradictions and inconsistencies in the results. The aim of this study was to evaluate the association between polymorphisms of functional VDR with the susceptibility to pulmonary tuberculosis in a Mexican population.
Methods
A case control study was performed in, 257 patients with pulmonary tuberculosis and 457 healthy controls recruited from: family medicine clinics of the Mexican Social Security Institute. The VDR gene polymorphisms Fok I (rs 2228570), BsmI (rs1544410), ApaI (rs7975232) and TaqI (rs731236) were genotyped by TaqMan assays. Statistical analysis was performed using: Epi Info V-7 and SNP Stats software.
Results
No statistically significant associations were observed in genotype and haplotype distribution between BsmI, ApaI and TaqI polymorphisms and disease susceptibility. The CC genotype for the VDR gene FokI was significantly more frequent in patients than in controls (29.6% versus 17.5%, OR = 1.97; 95% CI = 1.37-2.8, PC = 0.0004). Moreover, TT genotype was decreased in patients as compared to the control group (24.1% versus 34.8%, OR = 0.59; 95% CI = 0.42-0.84, PC = 0.004).
Conclusion
To our best knowledge, this is the first case-control study that finds an association between CC genotype of FokI SNP in the VDR gene with pulmonary tuberculosis in Mexican patients. However more validation studies should be performed to prove our conclusions.
