A large-scale genetic study of 26,000 people has identified seven locations on the genome where differences in the genetic code are associated with asthma. The findings suggest that allergies may be a consequence of asthma rather than a cause, and that genetic testing is unlikely to predict who will develop the disease.
Researchers at the NHLBI found that adding tiotropium bromide to low-dose inhaled corticosteroids is more effective than doubling corticosteroids alone and as effective as adding a long-acting beta agonist. The treatment showed significant improvements in asthma control, including increased symptom-free days.

A long-acting beta-agonist (LABA) is the most effective step-up treatment for children with poorly controlled asthma, according to a new study. The study found that children responded differently to different treatments, with African-Americans equally likely to respond best to LABA or corticosteroid step-up.
Research by National Jewish Health faculty presents promising findings on vitamin D's effectiveness in boosting corticosteroid efficacy for asthma treatment. Additionally, early results show oral immunotherapy with egg-white solid to be effective in desensitizing children with egg allergy.
A new study found that increasing dosage or adding asthma drugs to low-dose inhaled corticosteroids improves asthma control in 98% of children. LABA shows the highest response rate, but individual patients require personalized treatment due to factors like Asthma Control Test score, eczema, and ethnicity.

Researchers found that a culturally-tailored intervention providing feedback on secondhand smoke exposure was more effective in helping these parents quit smoking.
The prevalence of any chronic condition among US children has significantly increased over two decades, with obesity being one of the most prevalent conditions. The study found that having a chronic condition was dynamic over time, and different groups had varying rates of new cases and remission.
A study found that parents of children with asthma often recognize signs of an impending attack but delay treatment, leading to missed opportunities for early intervention. Researchers suggest that education and awareness can help parents identify early warning signs and take action sooner.
A large-scale study found that estrogen-only hormone replacement therapy (HRT) may increase the risk of developing asthma after menopause. Women who used estrogen-only HRT were 21% more likely to develop asthma than those who never used HRT, with a significant increased risk among non-smokers and those with previous allergies.
