Combination inhaled steroid and long-acting beta(2)-agonist in addition to tiotropium versus tiotropium or combination alone for chronic obstructive pulmonary disease.

The long-acting bronchodilator tiotropium and single inhaler combination therapy of inhaled corticosteroids and long-acting beta(2)-agonists are both commonly used for maintenance treatment of chronic obstructive pulmonary disease. Combining these treatments, which have different mechanisms of action, may be more effective than the individual components. However, the benefits and risks of using tiotropium and combination therapy together for the treatment of chronic obstructive pulmonary disease are unclear.

Researchers Link Novel Biomarkers To Asthma And COPD

Four novel biomarkers have been identified which may aid in the diagnosis and management of asthma and chronic obstructive pulmonary disease (COPD), according to a study conducted by researchers in Australia, who determined the biomarkers may be used in different combinations to successfully identify patients with either of the airway diseases.

In conducting the study, the researchers relied on proteomics, an emerging field of science that focuses on the structure and functions of an organism's proteins... ()

New Technique May Help Diagnose Asthma, COPD

Researchers in Australia have identified four molecular characteristics, or biomarkers, of asthma and chronic obstructive pulmonary disease (COPD), which they say could lead to better ways to diagnose the respiratory conditions.

Swimming pool use ‘does not increase asthma risk in children’

Results from a longitudinal UK study of children suggests that regular swimming pool use does not increase the risk for asthma and allergies.

Simple Blood Test Detects Early Emphysema In Smokers Before Symptoms Appear

The new test measures particles that are shed by tiny blood vessels known as capillaries that surround air sacs (alveoli) in lungs. These particles are debris shed by ongoing injury to the air sacs -- damage that eventually results in devastation of the sacs and the "Swiss cheese" appearance of the lungs.

The alveoli are where critical gas exchanges occur: blood in the capillaries brings carbon dioxide from the rest of the body for release into the air sacs, and the oxygen in the sacs (taken in from breathing) is taken up by the blood and transported to the rest of the body...
