Children with severe therapy-resistant asthma (STRA) may have poorer lung function and worse symptoms compared to children with moderate asthma due to lower levels of vitamin D in their blood, according to researchers in London. Lower levels of vitamin D may cause structural changes in the airway muscles of children with STRA, making breathing more difficult. The study provides important new evidence for possible treatments for the condition.
A genetic variant may explain why some people with asthma do not respond well to inhaled corticosteroids, the most widely prescribed medicine for long-term asthma control. Researchers found that asthma patients who have two copies of a specific gene variant responded only one-third as well to steroid inhalers as those with two copies of the regular gene.
The flu is a contagious respiratory illness caused by influenza viruses.

The start of a new school year is a big transition after the long summer break, especially for families of children with asthma.

If you’re like most Americans, you spend much of your time indoors. Have you ever stopped to think about whether the air you’re breathing at home is healthy? Research has found that in some homes across America, the quality of indoor air can be worse than outdoor air. In part, this is because many homes are being built and remodeled tighter. You don’t have to be a building scientist to deal with the quality of air in your home; however, you should understand a few basics to get you started.

Your child has just been diagnosed with asthma. Are you ready to explain this complex disease in terms your child can understand? Here are some tips.
A peak flow meter is a small, easy-to-use instrument that reveals how well your lungs are working. It does this by measuring your peak expiratory flow, which tells you how fast you can blow out air after a maximum inhalation. You use the peak flow meter to help you identify lung performance patterns, which give you information to prevent asthma episodes and develop your asthma management plan.
