Registry is a unique and universal mechanism for group and individual approaches to managing patients, including those with severe asthma (SA) who require targeted therapy.The aim is to evaluate the clinical and organizational potential of the SA patient registry as a tool for group and individual approaches to patient management, as a way to describe and systematize the signs of bronchial asthma, comorbid diseases, and monitoring immunobiological therapy (using anti-IgE therapy as an example) in patients with SA in Sverdlovsk region.Methods. The subject of the study was the Territorial Registry of Patients with SA of the Sverdlovsk region. The registry effectiveness was assessed based on the clinical and organizational indicators, including monitoring the effectiveness of 3-year anti-IgE therapy in patients with SA with an allergic component.Results. From 2016 to 2023, both inclusive, 198 patients with SA were entered into the registry. Analysis of the registry data allowed us to develop a scheme for SA phenotyping and selecting the 1st and 2nd line targeted drugs and a scheme for phenotyping and selecting a targeted drug for T2 inflammatory nasal diseases. Over 3 years of anti-IgE therapy with omalizumab, the ACT test increased from 9.00 to 19.50 points, the proportion of patients with partial and good asthma control increased by 13.89 times, the frequency of exacerbations decreased by 71.43%, FEV1 increased by 17.91%, and the proportion of patients requiring systemic corticosteroids decreased by 83.32%.Conclusion. The registry of SA patients has high clinical and organizational potential to describe and systematize the signs of bronchial asthma, comorbid diseases, and monitor the effectiveness and safety of immunobiological therapy. The 3-year anti-IgE therapy demonstrates statistically significant effectiveness in patients with SA with an allergic component.
