[Chronic obstructive pulmonary disease (COPD) as a systemic disease]

Abstract

Chronic obstructive pulmonary disease (COPD) is defined as a progressive, usually only partially reversible, obstruction of the airways The disease is associated with an inflammatory response of the lungs to noxious particles, particularly cigarette smoke. Numerous epidemiological studies have shown a significant association between impaired lung function and the presence of cardiovascular, metabolic or other extrapulmonary comorbidities. Systemic inflammation may be the missing link between COPD and its extrapulmonary manifestations, although the exact mechanism of this relationship remains unclear. The development and validation of score systems that classify COPD severity, not only by changes in lung function, is an important step. The BODE score (body-mass index, airways obstruction, dyspnea, exercise capacity) is such a system. Based on the concept of COPD as a systemic disease, a concept is needed which describes in detail the pharmacological treatment of the pulmonary and extrapulmonary manifestations of the disease. In addition, the part of the disease that is treatable with physiotherapy and rehabilitation must be fully taken into account. Such multimodal treatment regimens have so far not been implemented into clinical guidelines.
