Chronic obstructive pulmonary disease, or COPD, includes a number of lung conditions, including emphysema and chronic bronchitis. Almost all COPD the deaths are due to a sudden aggravation of symptoms (pulmonary attacks), often caused by viral infections of the upper respiratory tract, the researchers explained.
"New treatments are urgently needed to prevent COPD attacks." Our study shows that giving supplements at Vitamin DDepressed COPD patients halve their rate of life-threatening attacks, "said lead researcher Adrian Martineau, a professor at Queen Mary University in London.
In this study, Martineau and colleagues analyzed data from 469 COPD patients from three different countries. clinical tests, which took place in the United Kingdom, Belgium and the Netherlands.
taking Vitamin D Supplements have been associated with a 45% reduction in pulmonary attacks in patients with vitamin D deficiency, but no reduction has been observed in patients with higher vitamin D levels, the researchers found.
The study was published on January 10 in the journal Thorax.
Vitamin D supplementation is safe and inexpensive, Martineau said. "This is therefore a potentially very cost-effective treatment that could be aimed at people with low levels of vitamin D after routine tests," he said in a press release issued by a university.
"About a fifth of COPD patients in the UK – about 240,000 people – have low levels of vitamin D," said Martineau.
COPD affects more than 170 million people worldwide and this disease caused an estimated 3.2 million deaths in 2015.
The researchers pointed out that since the data in their study came from only three trials, the results should be interpreted with some caution.
Earlier research conducted by Queen Mary University revealed that vitamin D helps protect against colds, flu and asthma.
