Simultaneous estimation of glucocorticoid content was carried out in bronchial secretion products and in blood plasma of 95 children with chronic bronchopulmonary pathology. 11-hydroxycorticosteroids were found in bronchial secretion product; its concentration depended on the type, phase of the disease and the character of bronchial mucose impairment. The highest content of 11-hydroxycorticosteroids was observed in purulent endo-bronchitis.

Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation, airway obstruction, and lung damage, often triggered by cigarette smoke. Dysregulated autophagy and inflammation are key contributors to its progression. Although double-stranded RNA-binding protein Staufen homolog 1 (STAU1), a multifunctional protein primarily involved in mRNA transport and localization, is identified as a potential biomarker, its role in COPD pathogenesis remains unclear.
