Reaching Beyond Disparity: Safely Improving Asthma Control in the At-Risk African-American Population

In the United States, substantial racial disparities exist in asthma prevalence, etiology, morbidity and mortality, particularly between African Americans and white Americans. African-American patients with asthma have inadequate access to appropriate healthcare, insufficient asthma management guidance from their physicians and poor adherence to asthma medications-all factors that may contribute to disproportionate morbidity. Historically, African Americans have been under-represented in clinical asthma studies, and a paucity of data exists surrounding asthma treatment response. One controversial study from 2006 suggests an increased safety risk with the use of long-acting β2-adrenergic agonists ILABAs) in African Americans. More recently, several studies have evaluated the use of LABAs in combination with an ICS in African-American populations. This article reviews the existing data on asthma treatment outcomes, with particular emphasis on the recently published short- and long-term stUdies of ICS/LABA products conducted in African-American populations with moderate-to-severe asthma. Overall. evidence suggests that if African-American patients with asthma are provided with access to well-trained physicians, appropriate asthma management and effective medications, existing disparities in asthma control between African-American and white populations may be overcome.
