Clinical and functional parameters in patients with occupational chronic obstructive pulmonary disease in the postcovid period

Introduction. Occupational chronic obstructive pulmonary disease (OCOPD) is a serious cause of disability. The SARS-CoV-2 infection has caused a new problem: a combination of OCOPD and postcovid syndrome. The task of an occupational pathologist is to identify markers of disorders in such patients and develop personalized methods of treatment and rehabilitation.Material and methods. The clinical and functional parameters in ninety men with chronic obstructive pulmonary disease (COPD) of occupational and non-occupational origin were analyzed: 30 OCOPD men with COVID-19, 30 OCOPD men without COVID-19, and 30 men with non-occupational COPD and COVID-19. Dyspnea (Borg scales, mMRC, CAT), spirometry (FVC, FEV1, FVC/FEV1) and quality of life (SF-36) were assessed. The three groups were compared using the Kraskel–Wallis test and the Mann–Whitney method in a pairwise comparison.Results. The CAT scores in group 1 are higher than in groups 2 and 3 (p
