Accelerated lung aging and chronic obstructive pulmonary disease.

The prevalence of chronic obstructive pulmonary disease (COPD) increases exponentially with aging. Its pathogenesis, however, is not well known and aside from smoking cessation, there are no disease-modifying treatments for this disease. Areas covered: COPD is associated with accelerating aging and aging-related diseases.

Relationship of Absolute Telomere Length With Quality of Life, Exacerbations, and Mortality in COPD.

Background: COPD is an age-related disease. The role of cellular senescence in COPD has not been fully elucidated. This study examined the relationship between telomere length of peripheral blood leukocytes and clinical outcomes, including health status, rate of exacerbations, and risk of mortality in individuals with COPD.
