Organization of biological therapy for patients with severe eosinophilic bronchial asthma in the Krasnoyarsk region

Patients with severe bronchial asthma, which remains uncontrolled despite the optimal basic therapy, carry a significant healthcare burden and require substantial financial investments. Severe asthma is a heterogeneous airway disease with complex pathophysiological mechanisms that can be broadly divided into inflammatory pathways with eosinophilic and non-eosinophilic inflammation.Aim. This study aimed to analyze the literature data on the use of targeted genetic engineering therapy in patients with severe bronchial asthma, as well as to analyze the organization of immunobiological therapy in the Krasnoyarsk Territory. The addition of targeted drugs for severe eosinophilic bronchial asthma based on phenotyping has proven to be effective and is recommended by all current guidelines. Today, several biologics targeting specific endotypes and phenotypes has been approved for the treatment of severe eosinophilic asthma worldwide. These are antibodies binding immunoglobulin E (omalizumab), antagonists of interleukin-5 (mepolizumab, reslizumab) and its receptor (benralizumab), as well as antibodies selectively binding to the IL-4 and IL-13 receptors (dupilumab). Eosinophilic inflammation therapy is a relatively new direction of asthma treatment, and understanding its long-term efficacy and safety is important.Conclusion. It is essential to differentiate patients with severe eosinophilic asthma from the general cohort of asthma patients, timely refer them to specialists who can prescribe this therapy and have experience with it, select the drug correctly, and monitor the patients during the treatment. This article describes organization of biological therapy for patients with severe eosinophilic bronchial asthma in the Krasnoyarsk Territory.
