Objective: To study the relationship between vitamin D deficiency, VDR gene polymorphism rs10735810 (A > G), and a missed abortion in the first trimester of gestation; to determine the predictors of its risk.

Research methods: 178 women aged between 18 and 41 were surveyed. The main group consisted of patients with miscarriage (n = 101), verified at the hospital stage (O02.0; O02.1), which were stratified by I group (n = 58, patients with the first miscarriage) and II groups (n = 43, patients with repeated miscarriage). The control group (n = 77) consisted of women with a successful pregnancy (Z34.0), which subsequently ended in delivery at term with a live fetus. Patients were surveyed and data was extracted from primary medical records. The level of 25(OH)D in the blood serum was investigated by mass spectrometry (n = 99). Genotyping for the vitamin D receptor gene polymorphism rs10735810 (VDR A > G) was performed for 177 patients. Statistical data analysis was performed via Statistica 10 and SAS JMP 11 application packages, using single-factor prediction for quantitative and binary factors, ROC analysis, and CHAID decision tree construction.

Results of the study: WE found that patients with miscarriage in the first trimester of gestation (n = 60) more frequently than those in the control group (n = 39) had vitamin D insufficiency (93.3% versus 76.9%, p = .0183) including its deficiency, occurring at 25(OH)D of blood <20 ng/ml (71.7% versus 51.3%, p = .0392). This pattern was found in patients with the first miscarriage, where significant differences in the frequency of vitamin D deficiency were also detected in comparison with the control group (80.0% versus 51.3%, p = .0026). No direct correlation was found between the frequency of miscarriages in the first trimester and the variant of the polymorphism of the vitamin D receptor gene (VDR A > G [rs10735810]); the GG genotype in patients with repeated miscarriages was even less frequent compared to the control group (14.0% versus 23.7%, p = .3344). However, the decision tree has identified four risk classes and has determined that the highest risk of missed abortion in the cohort studied is formed by three predicates: smoking, serum level 25(OH)D < 6.5 ng/ml and VDR AA and GG genotypes.

Conclusion: The data obtained show that vitamin D insufficiency plays a pathogenetically significant role in early reproductive losses associated with miscarriages, both first and recurrent.

Low Vitamin D	low D in Blood
Smoking	Low D in blood - typically 10 ng lower Low Vitamin D is worse for your health than smoking
Poor Vitamin D Receptor - A	Low D in cell of placeta or fetus

VitaminDWiki - Vitamin D Receptor

The risk of 44 diseases at least double with poor Vitamin D Receptor as of Oct 2019

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 13 known VDR activators

Resveratrol improves health (Vitamin D receptor, etc.) has the following

• The Vitamin D Receptor can restrict how much of the Vitamin D in the blood actually gets to cells
• Resveratrol is one of 11 ways to negate the Vitamin D Receptor restrictions
• Resveratrol is produced by several plants in response to injury or, when the plant is under attack by pathogens such as bacteria or fung
• Benefits of Reseveratrol, like Vitamin D, appears to be increased when used with other things
  • Quercetin and Curcumin in the case of Resveratro

18 articles in both of the categories Resveratrol and Vitamin D Receptor

Vitamin D Receptor category has the following

494 studies in Vitamin D Receptor category

Vitamin D tests cannot detect Vitamin D Receptor (VDR) problems
A poor VDR restricts Vitamin D from getting in the cells

See also: 47 studies in the Resveratrol category

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

Health problems include: Autoimmune (18 studies), Breast Cancer (20 studies), Colon Cancer (13 studies), Cardiovascular (23 studies), Cognition (16 studies), Diabetes (23 studies), Hypertension (9 studies), Infant (21 studies), Lupus (6 studies), Metabolic Syndrome (3 studies), Mortality (4 studies), Multiple Sclerosis (11 studies), Obesity (15 studies), Pregnancy (24 studies), Rheumatoid Arthritis (10 studies), TB (8 studies), VIRUS (33 studies),   Click here for details
Some health problems, such as Breast Cancer, Diabetes, and COVID protect themselves by reducing VDR activation

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

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

• "Although early first trimester miscarriage is common, occurring in approximately 15% of clinically recognized pregnancies, only 2%-3% of couples experience two or more miscarriages and 0.5%-1% experience three or more."
