Fawzy A, et al. - Researchers sought to investigate the association of thrombocytosis with chronic obstructive pulmonary disease (COPD) morbidity including reported acute exacerbation of COPD (AECOPD), respiratory symptoms and exercise capacity. They noticed association of thrombocytosis with higher likelihood of prior exacerbation and worse symptoms. Also, it was suggested that platelet count, a commonly measured clinical assay, may be a biomarker for moderate-severe COPD symptoms, guide disease classification and intensity of treatment.
