Ventilatory defects and treatable traits in very elderly patients

Area of Science:

• Gerontology
• Pulmonology
• Internal Medicine

Background:

• The treatable-traits (TT) approach is increasingly used for chronic respiratory diseases.
• Data on TTs in very elderly individuals (≥75 years) is limited.
• Understanding TTs in this demographic is crucial for effective disease management.

Purpose of the Study:

• To determine the frequency of pulmonary, extrapulmonary, and behavioral TTs in very elderly individuals residing in care centers.
• To investigate the association between extrapulmonary TTs and ventilatory defects, specifically airflow limitation and restrictive spirometry patterns.
• To highlight the need for clinical research in this vulnerable age group.

Main Methods:

• A study involving 234 individuals (median age 86 years) residing in elderly care centers.
• Participants underwent spirometry, atopy testing, fractional exhaled nitric oxide measurement, blood pressure, and pulse oximetry.
• Evaluation of pulmonary, extrapulmonary, and behavioral TTs, with airflow limitation and restrictive spirometry patterns as outcome variables.

Main Results:

• Pulmonary TTs were identified in 44.9% of participants.
• The most frequent extrapulmonary TTs included persistent systemic inflammation (47.0%), anemia (34.4%), depression (32.5%), and obesity (27.4%).
• Airflow limitation was associated with smoking, and restrictive spirometry patterns were associated with cognitive impairment (OR: 3.89).

Conclusions:

• A high frequency of various TTs was observed in very elderly individuals.
• A novel association between restrictive spirometry patterns and cognitive impairment was identified.
• There is an urgent need for further clinical research focusing on the very elderly and their chronic respiratory conditions.
