Asthma, Allergy, and Immunology
The Asthma/Allergy Translational-Clinical research group has two main objectives central to our mission of impacting the care of patients with asthma and atopy:
- Apply novel research methods to improve our understanding of the clinical immunopathology of allergic airway disease (including asthma and allergic rhinosinusitis)
- Actively collaborate with the therapeutics sector to study the clinical effectiveness of new asthma/allergy therapies.
Atopic asthma and allergic rhinosinusitis are the result of a dysregulated immune response to essentially harmless antigens in dust mites, animal dander, molds, and pollens. In susceptible individuals, this dysregulated immune response elicits systemic sensitization to these allergens (atopy) and local effector responses that lead to the symptoms of allergic rhinosinusitis (rhinorrhea, congestion, sinusitis) and asthma (episodic dyspnea, wheeze, and cough).
Current trends in translational research in asthma and allergy have sought to provide insight into the mechanisms of exacerbation through non-invasive means (e.g. sputum induction/nasal secretion analysis for cytokine and cells and measurement of exhaled NO). Additionally, there is a significant emerging effort in the study of the role and function of factors that a) regulate/dampen the immune response in infancy and adulthood and b) control resolution of exacerbated asthma/allergic rhinitis (e.g. circulating T-regulatory cells and airway dendritic cells).
Current trends in clinical asthma/allergy research continue with focusing on medications that are not only effective but have optimal patient compliance (e.g. determining the benefit of regular vs. as-needed inhaled steroids for mild asthma and the development of more ‘patient-friendly’, patient actuated inhaler devices).
Translational and clinical research projects run by investigators in the Boston University Pulmonary Asthma/Allergy Translational-Clinical research group:
- Study Site, Urban Environment and Childhood Asthma (URECA), a project of the Inner City Asthma Consortium (ICAC) (Principal Investigator: Dr. O’Connor)
- Efficacy of anti-IgE therapy in childhood asthma (ICATA) (Principle Investigator: Dr. O’Connor)
- Rapid Saliva Diagnostics in Asthma Exacerbations (Principal Investigator: Dr. Little)
- Immune markers of patients undergoing sublingual immunotherapy to cockroach allergen (ICAC) (Drs. Little and O’Connor)
- Impact of Pulmicort Turbuhaler on Health Outcomes in an Inner City Managed Care Asthma Patient Population (Principal Investigator: Dr. Hollingsworth)
- Inhaled Steroid as Regular Therapy in Early Asthma. 5 year study. Published study: START (Principal Investigator: Dr. Hollingsworth)
- Relationship of Interleukin-16 promoter/ORF Single Nucleotide Polymorphisms (SNPs) and Asthma Severity (Drs. Center, Little, and O’Connor)
Expertise and Novel Approaches Applied by Group Members:
Our translational research is focused on understanding the interaction between the allergic diathesis and pulmonary disease manifestation. Two specific examples are i) a multi-center longitudinal birth cohort study of the interaction between heredity, immune cell phenotype, and environment (including respiratory infections) on the development of symptomatic wheeze and asthma ii) applying a novel bead-based proteomic/microarray platform to rapidly analyze saliva and nasal secretions in patients with acute asthma exacerbations to determine etiology (viral, bacterial, allergen, or irritant). This latter project is the result of a recent fruitful collaboration between Investigators in the Pulmonary Center , the BU Goldman School of Dental Medicine, and the Department of Chemistry at Tufts University . In addition, BU is a study site in multiple NIH and industry sponsored clinical/translational studies of asthma pathogenesis in children and adults as well as clinical trials of new asthma therapies (as outlined above).
