[The effectiveness of targeted therapy of various genetically engineered biological drugs in the treatment of bronchial asthma].

This article presents the experience of successfully switching therapy from omalizumab 150 mg to benralizumab 30 mg/1 ml in a patient with a combined allergic and eosinophilic phenotype in the presence of hypersensitivity to nonsteroidal anti-inflammatory drugs. The effectiveness of biological therapy was evaluated when switching from omalizumab 150 mg subcutaneously at a dose of 600 mg for 36 weeks. Therapy for the drug benralizumab 30 mg/1 ml subcutaneously the first three injections monthly, the rest a month later for 52 weeks with bronchial asthma (BA), a severe uncontrolled course with a combined allergic and eosinophilic phenotype in the presence of hypersensitivity to nonsteroidal anti-inflammatory drugs in a patient Ch., born in 2004. Switching therapy from omalizumab 150 mg to benralizumab 30 mg/1 ml allowed to achieve complete control of asthma symptoms (AST = 23 points), to achieve the absence of asthma exacerbations during 52 weeks, restore respiratory function to normal values, as well as improve the quality of life. The study reflects the good tolerability, high efficacy and safety of biological therapy when switching from one genetically engineered biological drug (GIBP) omalizumab 150 mg to another GIBP benralizumab 30 mg/1 ml in severe uncontrolled asthma with a combined allergic and eosinophilic phenotype in the presence of hypersensitivity to nonsteroidal anti-inflammatory drugs. Therapy with benralizumab 30 mg/1 ml in severe BA has demonstrated a more effective clinically significant improvement in the course of the disease, control of symptoms of the disease. Reduction of exacerbations, normalization of respiratory function indicators, complete control of the disease has been achieved. Consequently, the use of different biological molecules for the therapy of BA with a combined allergic and eosinophilic phenotype contributes to achieving disease control, improving the patient's quality of life and reducing the dose of oral glucocorticosteroids. The targeted biological drug benralizumab 30 mg/1 ml has a targeted effect on the key links in the pathogenesis of severe uncontrolled asthma with a combined allergic and eosinophilic phenotype in the presence of hypersensitivity to nonsteroidal anti-inflammatory drugs and reduces the burden of severe disease.

[Principles of modern diagnosis and treatment of atopic dermatitis and bronchial asthma: Clinical case].

This article presents the experience of successful use of the drug dupilumab in a patient with severe atopic dermatitis and bronchial asthma. The effectiveness of biological therapy with dupilumab 300 mg subcutaneously for 52 weeks of T-2 associated diseases, including a combination of severe atopic dermatitis and bronchial asthma, uncontrolled course based on the case history of patient Ts., born in 2006 with the diagnosis "Main: atopic dermatitis, common form, severe course. Concomitant diagnosis: bronchial asthma, persistent course, uncontrolled, moderate severity". Dynamic monitoring of the total blood count with the calculation of the absolute number of eosinophils in peripheral blood was performed. The study showed high efficacy and safety of biological therapy with dupilumab 300 mg subcutaneously every 2 weeks for 52 weeks with a combination of severe atopic dermatitis and bronchial asthma, uncontrolled course in patient Ts (Born in 2006). The examination of the ALEX2 allergochip made it possible to establish the molecular components of the primary causal allergens, predict the course of an allergic disease, and carry out successful elimination measures against food allergens, preserving the maximum set of nutrients in the patient's diet. Dupilumab therapy in severe atopic dermatitis and uncontrolled bronchial asthma leads to clinically significant improvement in the course of diseases, control of disease symptoms. Atopic dermatitis shows a decrease in itching of the skin, normalization of sleep, improvement of quality of life. With bronchial asthma, a reduction in exacerbations, normalization of respiratory function indicators, complete control of the disease has been achieved. The targeted biological drug dupilumab has a targeted effect on the key links in the pathogenesis of atopic dermatitis and bronchial asthma and reduces the burden of severe diseases. Therefore, the use of dupilumab in atopic dermatitis and bronchial asthma contributes to achieving disease control and improving the patient's quality of life.
