Asthma in the elderly: diagnosis and management

Area of Science:

• Geriatric Medicine
• Pulmonology
• Allergy and Immunology

Background:

• National Asthma Education and Prevention Program guidelines apply broadly but require age-specific adaptations for elderly patients.
• Elderly individuals with asthma are a heterogeneous group with varied onset, severity, and frequent comorbidities, including other lung diseases.
• Irreversible airway obstruction is common in this population due to airway remodeling, COPD, or bronchiectasis.

Purpose of the Study:

• To review specific diagnostic and management considerations for asthma in the elderly population.
• To address the unique challenges and adaptations needed for older adults with asthma.

Main Methods:

• Review of existing guidelines and literature on asthma in the elderly.
• Discussion of diagnostic tools, including imaging, for identifying comorbidities.
• Analysis of pharmacologic and non-pharmacologic treatment strategies tailored for older adults.

Main Results:

• Diagnosis may require chest radiography and CT scans to rule out other lung diseases if FEV1 remains low.
• Asthma pathogenesis involves IgE-mediated allergy and innate immune inflammation; environmental exposures are crucial.
• Elderly patients show reduced bronchodilator response and increased side effects from beta-agonists and glucocorticoids.

Conclusions:

• Asthma management in the elderly necessitates individualized strategies considering comorbidities and potential for irreversible airway obstruction.
• Nebulizers or oral medications may be preferable delivery systems due to inhalation difficulties and peripheral airway efficacy.
• Leukotriene antagonists and low-dose theophylline can be valuable adjuncts; oral glucocorticoids may be needed for severe cases.
