COPD and Smoking: January 2007 Archives

COPDJanuary 8, 2006 — Independent of smoking, chronic cough and phlegm in young adults are strong predictors of increased risk of developing chronic obstructive pulmonary disease (COPD), according to the results of a study reported in the January 1 issue of the American Journal of Respiratory and Critical Care Medicine.

"The few prospective studies aimed at assessing the incidence of chronic obstructive pulmonary disease (COPD) in relation to the presence of chronic cough/phlegm have produced contrasting results," write Roberto de Marco, MD, of the University of Verona in Italy, and colleagues. "The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines have introduced a stage 0 (normal spirometry, but presence of chronic cough or phlegm) in the COPD staging system as a tool to identify subjects at risk of developing the disease later in life."
