Samenvatting

OBJECTIVES: Little is known about the effect of bronchoscopic lung volume reduction using endobronchial valves (BLVR-EBV) on extrapulmonary manifestations like body composition, muscle function or metabolism. Pulmonary rehabilitation (PR) clearly addresses extrapulmonary manifestations of COPD, including physical inactivity and low muscle mass. However, the added impact of BLVR-EBV+PR remains unknown. Therefore, this study aimed to assess the effect of BLVR-EBV on body composition, muscle function and metabolic markers and whether PR has an additional impact on these outcomes.

METHODS: Subjects with severe COPD eligible for both PR and BLVR-EBV were randomized into three groups: PR+BLVR-EBV, BLVR-EBV+PR, or only BLVR-EBV (n=97). Assessments included Dual Energy X-ray Absorptiometry, thigh muscle Computed Tomography, muscle strength measurements, accelerometry, and plasma (leptin, adiponectin, insulin, and triglycerides) at baseline and six months after the last intervention.

RESULTS: A total of 74 participants completed the study. At follow-up, there were significant increases in the groups combined and both groups separated in total weight, lean mass, fat mass, muscle strength, daily physical activity, and triglyceride levels while leptin/fat mass ratio levels were significantly reduced. No differences were found between groups who underwent BLVR-EVR alone or BLVR-EBV with PR.

CONCLUSIONS: BLVR-EBV results in significant increases in body weight, lean and fat mass, muscle strength and daily physical activity level, and impacts on adipokine profile, irrespective of PR. This underscores the systemic benefits of addressing lung hyperinflation in patients with severe COPD.
