The Origins and Characteristics of Asthma

Part of the Current Clinical Practice book series (CCP)


  • Asthma has become a common medical problem in the United States, especially among blacks.

  • Wheezing is a frequently encountered pediatric problem. When wheezing is recurrent, asthma is an important consideration.

  • Risk factors for pediatric asthma are strongly associated with genetics (parental) and being atopic.

  • Adult-onset asthma is more common in females, but other risk factors, as seen in children, are not as strongly associative.

  • Asthma many relapse after years of quiescence.

  • Asthma is characterized by bronchoconstriction, bronchial hyperresponsiveness, βadrenergic blockade, and inflammation.

  • Pulmonary eosinophilia is a common feature of asthma.

  • Increased exhaled nitric oxide is a marker of inflammation.

  • Specific T-cell cytokines are unique to asthma, including interleukin (IL)-4, IL-5, and IL-13.

  • IL-13 may play an important role in asthma pathogenesis.
