Federal guidelines on diagnosis and treatment of bronchial asthma

Bronchial asthma is a heterogeneous disease that requires identification of its phenotype and a personalized approach to therapy. At the same time, despite a wide range of therapeutic options, many patients with asthma cannot achieve control over the disease.

Methodology. The target audience of these clinical recommendations are general practitioners, therapists, pediatricians, allergologists-immunologists, pulmonologists, and functional diagnostics doctors. Each thesis-recommendation about diagnostic and therapeutic procedures has been scored according to the scales of classes of recommendations from 1 to 5 and A, B, C scale of the levels of evidence. The clinical recommendations also contain comments and explanations to the theses, algorithms for the diagnosis and treatment of bronchial asthma, and reference materials.

Conclusion. The presented clinical guidelines cover current information about the etiology and pathogenesis, classification, clinical manifestations, diagnosis, treatment, and prevention of bronchial asthma. These guidelines were approved by the Scientific and Practical Council of the Ministry of Health of the Russian Federation in 2021.
