Vitamin D deficiency may increase risk for addiction to opioids and ultraviolet rays

Vitamin D deficiency may increase risk for addiction to opioids and ultraviolet rays - رد پای ویتامین D در اعتیاد

Lab animals deficient in vitamin D crave and become dependent on opioids, which is curbed when normal levels of the vitamin are restored.
Human health records indicate that people with low vitamin D are more likely to use and misuse opioids.
Study results suggest a potential role for vitamin D supplementation in fighting opioid addiction.

Vitamin D deficiency strongly exaggerates the craving for and effects of opioids, potentially increasing the risk for dependence and addiction, according to a new study led by researchers at Massachusetts General Hospital (MGH). These findings, published in Science Advances, suggest that addressing the common problem of vitamin D deficiency with inexpensive supplements could play a part in combating the ongoing scourge of opioid addiction.

Over 80 percent of COVID-19 patients have vitamin D deficiency

Over 80 percent of COVID-19 patients have vitamin D deficiency - اکثریت بیماران مبتلا به کووید 19 دچار کمبود ویتامین دی هستند

Over 80 percent of 200 COVID-19 patients in a hospital in Spain have vitamin D deficiency, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.

Vitamin D is a hormone the kidneys produce that controls blood calcium concentration and impacts the immune system. Vitamin D deficiency has been linked to a variety of health concerns, although research is still underway into why the hormone impacts other systems of the body. Many studies point to the beneficial effect of vitamin D on the immune system, especially regarding protection against infections.

The researchers found 80 percent of 216 COVID-19 patients at the Hospital Universitario Marqués de Valdecilla had vitamin D deficiency, and men had lower vitamin D levels than women. COVID-19 patients with lower vitamin D levels also had raised serum levels of inflammatory markers such as ferritin and D-dimer.

Vitamin D deficiency may raise risk of getting COVID-19

Vitamin D deficiency may raise risk of getting COVID-19 - کمبود ویتامین دی خطر ابتلا به بیماری کرونا را افزایش می دهد

In a retrospective study of patients tested for COVID-19, researchers at the University of Chicago Medicine found an association between vitamin D deficiency and the likelihood of becoming infected with the coronavirus.

“Vitamin D is important to the function of the immune system and vitamin D supplements have previously been shown to lower the risk of viral respiratory tract infections,” said David Meltzer, Chief of Hospital Medicine at UChicago Medicine and lead author of the study. “Our statistical analysis suggests this may be true for the COVID-19 infection.”

The research team looked at 489 patients at UChicago Medicine whose vitamin D level had been measured within a year before being tested for COVID-19. Patients who had vitamin D deficiency (defined as less than 20 nanograms per milliliter of blood) that was not treated were almost twice as likely to test positive for COVID-19 compared to patients who had sufficient levels of the vitamin.
