Children exposed to high indoor levels of pet or pest allergens during infancy have a lower risk of developing asthma by 7 years of age, new research supported by the National Institutes of Health reveals. The findings, published September 19 in the Journal of Allergy and Clinical Immunology, may provide clues for the design of strategies to prevent asthma from developing.

May is Asthma Awareness Month, and the National Institutes of Health is finding solutions to improve the health of the nearly 25 million people in the United States who currently have asthma. In recent decades, the prevalence of asthma has been increasing, resulting in millions of urgent medical visits and missed days of work and school each year.
Genetically engineered mice serve as valuable models of human disease, contributing to major medical breakthroughs. Often, biomedical researchers must develop unique genetically modified strains of mice for experimentation, a costly and time-consuming process. Now, more researchers in fields from immunology to cancer may be able to save time and money by acquiring genetic material from a repository of previously engineered strains.
In a novel study of 717 children between ages 6 and 17, researchers have identified major factors associated with asthma severity in children from inner-city communities. They found that poor lung function, sensitivity to certain inhaled allergens, and exposure to second-hand smoke were important factors affecting asthma severity. The National Institute of Allergy and Infectious Diseases (NIAID) funded the work with additional support from the National Center for Advancing Translational Sciences, both parts of the National Institutes of Health (NIH).
The microbial communities, or microbiota, that naturally colonize the digestive tract in very young infants can affect their risk of later developing childhood allergies and asthma. Scientists now have identified a specific type of microbiota composition and corresponding metabolic environment in the neonatal gut that appears to influence immune cell populations and promote allergy and asthma development. The work was funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
On World Asthma Day 2016, the National Institutes of Health reaffirms its commitment to support research to improve the lives of all people with asthma. NIH-funded research has advanced our understanding of asthma as a disease as well as the impact asthma has on the lives of those affected.
Treatment with omalizumab significantly decreases the number of colds in inner-city children with allergic asthma, researchers reported at a press conference today at the American Academy of Allergy, Asthma and Immunology (AAAAI) 2016 Annual Meeting in Los Angeles.
Adding the drug omalizumab to ongoing guidelines-based asthma therapy for a targeted four-month period beginning just before the start of school reduced the number of autumn asthma attacks, or exacerbations, in inner-city children.
