Vitamin D supplements can reduce the risk of potentially fatal lung attacks in some patients with chronic obstructive pulmonary disease (COPD), suggests a new study.
COPD is a group of lung diseases including emphysema and chronic bronchitis that causes airflow blockage.
The study showed that the oral use of vitamin D supplements led to a reduction in lung attacks among COPD patients.
"Vitamin D supplementation is safe, and it costs just a few pence to supplement a person for a year so this is a potentially highly cost-effective treatment that could be targeted at those who have low vitamin D levels following routine testing," said lead researcher Adrian Martineau, Professor from the Queen Mary University of London.
For the study, published in the journal Thorax, the team included 469 patients across three clinical trials in the UK, Belgium and the Netherlands.
It was found that supplementation did not influence the proportion of participants experiencing serious adverse events, indicating that it was safe.
However, no benefit was seen for patients with higher vitamin D levels.
"New treatments are urgently needed to prevent COPD attacks. Our study shows that giving supplements to vitamin D-deficient COPD patients nearly halves their rate of potentially fatal attacks," Martineau noted.
While vitamin D is best known for its effects on bone health, previous studies have also revealed its role in protecting against colds, flu and asthma attacks, and even helping with weight gain and brain development in malnourished children.— IANS
