- Benefits of Vitamin D often limited by genes
- Vitamin D level can be high, but little benefit: due to kidney, genes, low Magnesium etc.
- Vitamin D dose size needed – VitD testing tells only a portion of the story – Jan 2016
- How to significantly reduce your risk of contracting the Zika virus Zika and Dengue are very similar
Vitamin D Receptor activation can be increased by any of: Resveratrol, Omega-3, Magnesium, Zinc, Quercetin, non-daily Vit D, Curcumin, intense exercise, Ginger, Essential oils, etc Note: The founder of VitaminDWiki uses 10 of the 12 known VDR activators
Items in both categories Virus and Vitamin D Receptor are listed here:
- COVID kids were more likely to have a poor VDR (4.3 X), than low Vitamin D (2.6 X) – Sept 2022
- Cancers are associated with low vitamin D, poor vaccination response and perhaps poor VDR – July 2022
- COVID 3X more likely if a poor Receptor (cells get less Vitamin D from the blood) – July 2022
- Long-COVID is now the biggest COVID concern - many studies
- COVID death 12X more likely if poor Vitamin D Receptor (less D gets to cells) -several studies
- COVID severity, ICU, and mortality all associated with poor vitamin D receptor (but not D, everyone had low D) -Dec 2021
- Different Vitamin D Receptor problems cause different COVID problems - Dec 2021
- COVID-19 severity associated with 3 vitamin D genes – Oct 2021
- Poor Vitamin D receptor blocked Vitamin D from fighting avian influenza viruses (in mice) – July 2021
- Epstein-Barr is yet another virus that deactivates the Vitamin D receptor (COVID later suspected as well)– 2010
- COVID-19 symptoms and comorbidities associated with the type of Vitamin D Receptor – Oct 2021
- Enveloped virus infection (RSV, coronavirus, HIV, etc.) 1.5X more likely if poor Vitamin D Receptor – meta-analysis Dec 2018
- COVID-19 outpatients getting Quercetin nanoemulsion had excellent outcomes (Q increased Vitamin D in cells) – RCT – June 2021
- A virus that most adults have (Cytomegalovirus) decreases the amount of Vitamin D which gets to the cells – Jan 2017
- COVID virus alters the activation of 100 vitamin D related genes in the lung – April 2021
- Common sense COVID-19 risk reduction - masks, social distancing, vitamin D - Oct 2020
- AI is examining 170,000 potential COVID-19 treatments, Vitamin D is one of only 6 found – Sept 4, 2020
- Vitamin D Receptor activation should reduce ARDS associated with COVID-19 - June 2020
- Dengue viral production decreased 1000X if activate Vitamin D Receptor (in lab) – July 2020
- Vitamin D, Quercetin, and Estradiol all increase vitamin D in cells and increase genes which reduce COVID-19 – May 21, 2020
- Quercetin and Vitamin D - Allies Against COVID-19
- Risk of enveloped virus infection is increased 50 percent if poor Vitamin D Receptor - meta-analysis Dec 2018
- Hand, foot, and Mouth disease is 14X more likely if poor Vitamin D Receptor – Oct 2019
- Treating herpes reduced incidence of senile dementia by 10 X (HSV1 reduces VDR by 8X) – 2018
- Severe hand, foot, and mouth virus is 2.9 X more likely if poor Vitamin D receptor – Oct 2018
- Hepatitis B virus reduced by 5X the Vitamin D getting to liver cells in the lab – Oct 2018
- Some enveloped virus are 1.2 X more likely if have a poor Vitamin D Receptor -Aug 2018
- Severe Pertussis is 1.5 times more likely if poor vitamin D receptor – Feb 2016
- Dengue Fever associated with poor vitamin D receptor – July 2002
- Dengue virus 2X to 4X more likely if vitamin D receptor gene problems
Vitamin D is known to affect pathogenesis of dengue through modulation of immune responses.
Vitamin D exerts its effects through vitamin D receptor (VDR).
The functioning of VDR is affected by the gene polymorphisms in the coding (rs2228570) and 3'untranslated region (UTR) (rs1544410, rs7975232 and rs731236). In the present study, VDR gene polymorphisms were investigated in 112 dengue infected patients (83 dengue fever (DF) and 29 dengue hemorrhagic fever cases (DHF)) and 105 apparently healthy controls (HCs) using polymerase chain reaction based restriction fragment length polymorphisms methods. HCs had no documented evidence of symptomatic dengue. Results revealed significantly lower frequency of 'C' allele of rs7975232 in all dengue patients (DEN) as compared to HCs [(P corrected (Pc)=0.014, Odds ratio (OR) 0.51]. The frequency of C/C genotype of rs7975232 was significantly lower in DEN and DF cases compared to HCs (DEN vs. HCs: Pc=0.0184, OR 0.24; DF cases vs. HCs: Pc=0.028, OR 0.21). The frequency of T allele of rs2228570 in a dominant mode was significantly higher in DHF cases as compared to DF cases (P=0.034 OR 2.58). A significantly lower frequency of the haplotype G-C-T (Pc=0.0135) and higher frequency of the haplotype G-A-T (Pc=0.000085) was observed in DEN and DF cases as compared to HCs. The results suggest that the 3'UTR haplotypes of VDR gene are differentially associated with risk of symptomatic dengue requiring hospitalization. The 'T' allele of rs2228570 polymorphism in a dominant mode of inheritance is associated with DHF.
