Lower levels of vitamin D may be effective in treating asthma, according to the latest study published in the journal of Allergy and Clinical Immunology.
researcher Prof Catherine Hawrylowicz.
Interleukin-17 plays very important role in the immune system as its combat with various types of infections. Higher levels of interleukin-17 can worsen the condition of asthma. During this study researchers determine the link between interleukin-17 and vitamin D.
They found a significant reduction in levels of interleukin-17 in patient who were given vitamin D after taking their blood samples. Now researchers are conducting clinical trials to determine whether vitamin D provides relief in asthma patients who are unable to get any effective response from steroids. Patients who do not respond to steroid therapy is due to the presence of different types of interleukin -17.
Prof Catherine Hawrylowicz told the BBC: “We think that treating people with vitamin D could make steroid-resistant patients respond to steroids or let those who can control their asthma take less steroids.”
She said a culture of covering up in the sun and using sun cream may have increased asthma rates, but “it is a careful message because too much sun is bad for you”.
Malayka Rahman, from the charity Asthma UK, said: “For the majority of people with asthma, current available medicines are an effective way of managing the condition but we know that they don’t work for everyone, which is why research into new treatments is vital.
“We also know that many people with asthma have concerns about the side effects of their medicines so if vitamin D is shown to reduce the amount of medicines required, this would have an enormous impact on people’s quality of life.
“We look forward to the results of the clinical trial.”
