Chronic Obstructive Pulmonary Disease (COPD) is one of the leading cause of death worldwide and represents one of the major causes of chronic morbidity. Cigarette smoking is the most important risk factor for COPD. In these patients, the airflow limitation is caused by a mixture of small airways disease and parenchyma destruction, the relative contribution of which varies from person to person. The two-fold nature of this pathologic condition has been studied in the past and according to many authors each patient with COPD, although being the individual clinical expression of a wide and continuous spectrum of pathologic changes (different lesions may coexist) causing expiratory airflow limitation, should be classified as presenting a predominantly bronchial or emphysematous COPD phenotype by simple clinical, functional, and radiological findings.



A model to identify COPD phenotype.

Our research group has recently developed and validated a multivariate model reflecting the specific predominant mechanism of airflow limitation for a given patient. The model was trained over a database of hundreds of patients and detailed explanation could be found in: "Pistolesi M, Camiciottoli G, Paoletti M et al. Identification of a predominant COPD phenotype in clinical practice. Respiratory Medicine 2008;102:367-376."
