Background:
Mean platelet volume (MPV), reflecting the platelet production rate and stimulation, is an inflammatory marker for cardiovascular disease, inflammatory bowel disease, and rheumatoid arthritis. However, the associations between MPV and chronic obstructive pulmonary disease (COPD) are not in agreement.
Methods:
Ninety participants with an exacerbation of COPD were investigated, and were reassessed when convalescent. Ninety controls were matched for age, gender, body mass index, smoking index, and medication use. Blood samples were collected for measurements of MPV and other laboratory data, and pulmonary function was also assessed.
Results:
MPV is significantly increased in convalescent COPD patients compared with healthy controls, and further increased in COPD patients with an acute exacerbation. MPV was positively correlated with high-sensitivity C-reactive protein both in the exacerbation and convalescence periods of COPD, and negatively correlated with FEV1 % predicted and FEV1/FVC in the convalescent COPD patients.
Conclusions:
MPV may be regarded as a quick and reliable tool in the assessment of inflammatory response in the progression of COPD.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
