Asthma in the inner city: The perspective of the National Institute of Allergy and Infectious Diseases

Since 1991, the National Institute of Allergy and Infectious Diseases (NIAID) has funded four consecutive research initiatives to investigate the problem of high asthma prevalence, morbidity and mortality in poor urban communities. The multi-site studies conducted under these initiatives have identified key risk factors for asthma morbidity and novel interventions to improve asthma control. NIAID focuses its asthma and allergy programs on understanding the interaction of the immune system with allergens and infectious agents and identifying genetic and epigenetic elements that influence the immune system. A key goal in this field is to define mechanisms of immune system deviation and immune tolerance and apply this knowledge to generate improvements in asthma care and allergen immunotherapy. A related goal is to further understand the environmental, social, and immunological elements that impact on the development of inner-city asthma through in-depth characterization and longitudinal follow-up of inner-city children from the time of birth. In the past 5 years, NIH budgetary constraints have imposed many challenges for the academic research community. Despite these constraints, NIAID has maintained its support of a highly productive asthma and allergy research program.
