Abstract

The purpose of the study was to identify the relationship between the level of blood serum hyaluronic acid (HA) and the exacerbation history of occupational COPD caused by exposure to silica dust.

Methods: Former internship workers in mechanical engineering were the subject of the study. The research met ethical standards.

Clinical characteristics of the patients, Me [Lq; Uq]

The concentration of HA in the blood serum of patients in group 3 was significantly higher by 25% than in patients with rare exacerbations (p=0.004).

Correlations (p<0.05) were retrieved between: HA and eosinophils (r=0.18), HA and exacerbation history (r = 0.32), HA and FEV1 (r = -0.23), FEV1 and exacerbation history (r =-0.32), eosinophils and exacerbation history(r = 0.2).

Conclusion: detection of the amount of HA in the blood serum in patients with occupational COPD can be used in clinical practice as a biomarker for assessing the risk of exacerbations and progression of bronchopulmonary pathology.
