Indoor and outdoor pollutants and allergens

Charles S. Barnes in Asthma, COPD, and Overlap: A Case-Based Overview of Similarities and Differences

Pollution is a normal result of human activity. It is the unwanted introduction of something into the environment that causes harm. In a comparative risk assessment of the global burden of disease, both ambient air pollution and indoor air pollution were among the most significant factors. The interests of health are constantly colliding with the interests of economic development, which further confound issues related to air quality. Regardless of one’s perspective, having an essential understanding of the impact of environmental determinants on respiratory conditions such as asthma and COPD is necessary for effective management of these patients.

Adverse health conditions and diseases affecting the respiratory and cardiovascular systems of vulnerable populations, such as children, the elderly, and those with preexisting cardiopulmonary illnesses, represent the main health concerns related to air pollution. Included among these health endpoints are increased cardiopulmonary mortality, asthma exacerbation, chronic obstructive pulmonary disease (COPD), decreased heart rate variability,

The Effects of Air Pollution and Temperature on COPD

Published in COPD: Journal of Chronic Obstructive Pulmonary Disease

Chronic Obstructive Pulmonary Disease (COPD) affects 12–16 million people in the United States and is the third-leading cause of death. In developed countries, smoking is the greatest risk factor for the development of COPD, but other exposures also contribute to the development and progression of the disease. Several studies suggest, though are not definitive, that outdoor air pollution exposure is linked to the prevalence and incidence of COPD. Among individuals with COPD, outdoor air pollutants are associated with loss of lung function and increased respiratory symptoms. In addition, outdoor air pollutants are also associated with COPD exacerbations and mortality.

The effect of environmental factors on the differential expression of miRNAs in patients with chronic obstructive pulmonary disease: a pilot clinical study

Published in International Journal of Chronic Obstructive Pulmonary Disease » Volume 13

COPD is a common chronic disease of the respiratory system, which is characterized by airflow obstruction caused by small airway disease (bronchiolitis obliterans) and destruction of lung parenchyma (emphysema). With increases in air pollution, smoking and age, the incidence and mortality of COPD have increased significantly. Acute exacerbation of COPD can lead to a decrease in the quality of life of patients, a decline in lung function and an increased risk of death.
