Dramatic Strides Against Childhood Asthma
Better Medicines Helping Kids With Asthma Fare Better Than in Years Past
March 17, 2009 (Washington, D.C.) -- Kids with severe asthma can breathe a lot easier than they could a decade ago.
Thanks in large part to better medications, children with severe asthma are less likely to wheeze and suffer full-blown asthma attacks today than 10 years ago, researchers report. They’re less likely to have to swallow steroid pills every day to calm airway inflammation, which means fewer side effects of long-term use, such as thinning bones or stunted growth.
The list goes on. Children are now less likely to have to reach for rescue inhalers for quick relief of worsening symptoms. And their lungs generally function better, says researcher Joseph Spahn, MD, a children’s asthma specialist at National Jewish Health in Denver.
“If your child has asthma and is suffering, he shouldn’t be,” Spahn says. “Even severe symptoms should be controlled, and the child should be able to go about most normal activities,” he tells WebMD.
Newer Asthma Medications Better and Safer
Spahn credits several types of newer medications with the dramatic improvement. Among them:
“The second-generation steroids are much more potent than the first-generation drugs. In general, they also cause fewer adverse events, such as growth suppression or [brittle bones],” Spahn says.
- The highly popular Advair, which combines an inhaled steroid with a long-acting bronchodilator. Bronchodilators relieve the symptoms of asthma by temporarily relaxing the muscle bands that tighten around the airways.
Xolair, which blocks proteins in the immune system from becoming activated, an underlying cause of allergic asthma symptoms.
Children With Severe Asthma Healthier Than in Years Past
For the study, Spahn and colleagues reviewed the medical records of 65 children 6 to 18 referred to their clinic for severe asthma between 2004 and 2007. They were compared to 163 children of the same ages treated for severe asthma between 1993 and 1997.
Among the findings, presented at the annual meeting of the American Academy of Allergy, Asthma & Immunology:
- Only 28% of children in the latter time period took steroid pills regularly vs. 51% a decade before. “Those who do take them today require a lower dose and a shorter course of treatment,” Spahn says.
- 89% of children in the latter time period took inhaled steroids vs. 98% a decade earlier.
- 66% of children with severe asthma in the latter time period took Advair. It wasn’t on the market in the 1990s.
- Children in the latter time period were more likely to be on a second-generation inhaled steroid. For example, 16% were taking Pulmicort vs. 0% a decade before.
- Children in the latter time period were in the 53rd percentile of height for their age vs. the 39th percentile 10 years earlier.
- None of the kids in the latter time period had cataracts, a side effect of first-generation steroids. This compares with 21% in the earlier time period.
