Asthma is a respiratory disease that currently affects around 300 million people worldwide and is defined by coughing, shortness of breath, wheezing, mucus overproduction, chest tightness, and expiratory airflow limitation. Increased levels of interleukin 17 (IL-17) have been observed in sputum, nasal and bronchial biopsies, and serum of patients with asthma compared to healthy controls. Patients with higher levels of IL-17 have a more severe asthma phenotype. Biologics are available for T helper 2 (Th2)-high asthmatics, but the Th17-high subpopulation has a relatively low response to these treatments, rendering it a rather severe asthma phenotype to treat. Several experimental models suggest that targeting the IL-17 pathway may be beneficial in asthma. Moreover, as increased activation of the Th17/IL-17 axis is correlated with reduced inhaled corticosteroids (ICS) sensitivity, targeting the IL-17 pathway might reverse ICS unresponsiveness. In this review, we present and discuss the current knowledge on the role of IL-17 in asthma and its interaction with the Th2 pathway, focusing on the rationale for therapeutic targeting of the IL-17 pathway.

Background: Oral corticosteroid (OCS) dependent asthma is one of the severe asthma phenotypes that requires personalized treatment. Objective: To review the role of biologic treatments in OCS-dependent asthma. Methods: A nonsystematic review was performed of emerging multiple novel biologics for potential treatment of OCS-dependent asthma. Results: The serious adverse effects of OCS can be seen as a result of their regular long-term administration. Anti‐interleukin (IL) 5 (mepolizumab), anti‐IL-5R (benralizumab), and anti‐IL-4Rα (dupilumab) are the therapies of choice for OCS-dependent severe asthma. Results of studies showed the efficacy of mepolizumab, benralizumab, and dupilumab, especially in patients with the OCS-dependent severe eosinophilic asthma phenotype and with nasal polyps. Dupilumab may be the therapy of choice of monoclonal antibodies in cases of moderate-severe atopic dermatitis accompanied by OCS-dependent severe asthma. For reslizumab and omalizumab, placebo controlled double-blind studies conducted with OCS-dependent patient populations are needed. Conclusion: Biologics are effective in the “OCS-dependent asthma” phenotype as add-on therapy. It seems that chronic OCS use in OCS-dependent asthma will be replaced by biologic agents that specifically target type 2 inflammation, along with a much better safety profile. However, real-life studies that compare these biologics in OCS-dependent severe asthma are urgently needed.

Обоснование. Тяжелая БА является гетерогенным и экономически затратным заболеванием, что требует персонифицированного подхода к лечению с включением таргетной терапии, предполагающей фенотипирование астмы. Цель. Определение динамики распространенности бронхиальной астмы (БА) на Среднем Урале, в том числе тяжелой БА, и проведение фенотипирования пациентов с тяжелой БА для определения потребности в таргетной терапии. Материалы и методы. Популяционные исследования распространенности БА проводились на Среднем Урале с 2000 по 2012 г. с использованием стандартного вопросника ECRHS создавались регистры больных БА. В 2018 г. в г. Екатеринбурге проведен анализ амбулаторных карт пациентов с БА (n216). Фенотипирование БА проводилось врачом аллергологом-иммунологом. Результаты. На Среднем Урале за 17 лет число больных БА увеличилось в 2,7 раза. В популяции превалируют больные с легким течением астмы в 70,8-81 случаев преобладает атопический фенотип вне зависимости от категории населения. В структуре зарегистрированных по обращаемости больных астмой тяжелая неконтролируемая БА составляет 10,2. Каждый второй пациент с тяжелой неконтролируемой астмой имеет атопический фенотип, что составляет 5 от числа всех случаев БА каждый четвертый больной из данной группы имеет эозинофильной фенотип, что составляет 2,3 от числа всех случаев (n216). Заключение. Фенотипирование БА имеет важное прикладное значение для планирования эффективной таргетной терапии в популяции больных тяжелой неконтролируемой астмой.Topicality. Severe asthma is a heterogeneous and cost-effective disease that requires a personalized treatment approach with inclusion of targeted therapy involving the phenotyping of asthma. Objective. Determine the dynamics of asthma prevalence in the Middle Ural, including severe asthma, and phenotype patients with severe asthma for the selection of targeted therapy. Materials and methods. Population studies of bronchial asthma prevalence were conducted in the Middle Ural from 2000 to 2012 using the standard ECRHS questionnaire. Also registers of patients with asthma were created. An analysis of outpatient records of patients with asthma was conducted in Ekaterinburg in 2018. The phenotyping of bronchial asthma was carried out by an allergist-immunologist. Results. The number of patients with bronchial asthma increased by 2.7 times over 17 years in the Middle Ural. Patients with mild asthma prevail in the population. The atopic asthma phenotype predominates in 70.8-81 of cases regardless of the population category. Severe uncontrolled bronchial asthma occurs in 10.2 of cases among all patients seeking medical care. Every second patient with severe uncontrolled asthma has an atopic phenotype, which is 5 of the total number of analyzed patients with bronchial asthma. Every fourth patient with severe uncontrolled bronchial asthma has an eosinophilic phenotype, which is 2.3 of all analyzed patients with bronchial asthma (n216). Conclusion. Phenotyping of asthma has important practical significance for planning effective targeted therapy in a population of patients with severe uncontrolled asthma.
