The article discusses different phenotypes of heterogeneous bronchial asthma (BA), methods of identification of patients with severe bronchial asthma, based on clinical characteristics, biological and genetic markers. Definition of phenotypes/ endotypes of BA contributes to better understanding of the nature of the disease and is feasible for development of an individual approach to therapy, because some types of BA may differ in resistance response to the standard treatment. The article gives an overview of modern research focused on the use of monoclonal antibodies in the treatment of BA. It discusses the algorithm of selection of patients with severe BA for prescribing of biological therapy.
Background. Intranasal corticosteroids and antihistamines are the basis of pharmacotherapy of allergic rhinitis (AR). The aim of this study was to evaluate the efficacy, safety and tolerability of Momat Rhino Advance (fixed combination of azelastine hydrochloride 140 mcg + mometasone furoate 50 mcg) intranasal spray in seasonal rhinitis patients. Materials and methods. Momat Rhino Advance was administered within 14 days in adults with seasonal AR in comparison with the original azelastine hydrochloride and mometasone furoate, used in combination with each other from separate devices against nasal (TNSS) and non-nasal (TNNSS) rhinitis symptoms. In total, 220 patients 18-65 years old with moderate/severe seasonal AR, were randomized in an open, parallel-group, multicenter clinical trial conducted in 16 centers in the Russian Federation during the period from April to September 2014. Results and conclusion. As a result of the study a marked decreasing of nasal symptoms using scale TNSS (in 89,6% relatively to the initial visit, p
Hereditary angioedema is a rare, potentially life-threatening genetic disease that manifests with skin and mucous/submucosal swelling that occurs under the influence of bradykinin. The clinical guidelines for hereditary angioedema (code for the International Statistical Classification of Diseases and Related Health Problems D84.1) were developed in December 2020 by the Russian Association of Allergology and Clinical Immunology, Association of Medical Geneticists, National Association of Experts in the Field of Primary Immunodeficiencies, Union of Pediatricians of Russia. In December 2020, the project was approved at a meeting of the Scientific and Practical Council of the Ministry of Health of the Russian Federation (December 10, 2020 No. 743/12). The clinical guidelines are devoted to optimizing the clinical care of patients with hereditary angioedema. The topic is relevant owing to the under-diagnosis of hereditary angioedema and insufficient awareness of doctors of various specialties about this problem, as well as the difficulties in managing this category of patients. The clinical guidelines contain information about the epidemiology, etiology, classification, pathogenesis, and common clinical manifestations of hereditary angioedema. Thus, the paper described actual diagnostic approaches and differential diagnosis of hereditary angioedema and established its diagnostic criteria. Medical care algorithms to patients with hereditary angioedema at the prehospital and hospital stages are also described. The principles of pharmacotherapy, including long-term prophylaxis, short-term prophylaxis, and acute therapy, for hereditary angioedema are also presented. Treatment regimens are stratified according to patients age and gender. Non-drug measures for the prevention hereditary angioedema attacks are considered. Sections were also added in the edition of the new clinical guidelines of hereditary angioedema. Clinical guidelines for hereditary angioedema are intended for practicing doctors of all specialties, students and teachers of medical universities, residents, graduate students of medical universities.
In many countries of the world and in Russia, in particular, the pharmacological use of antagonists of cysteinyl receptors LT1 (CysLTR) is a long-proven and well-proven pharmacotherapy of bronchial asthma (BA) and allergic rhinitis (AR) in adults and children. Among antileukotriene drugs the most commonly used medication for the treatment of these diseases is the original montelukast, which is considered a safe drug associated with the appearance of only a few adverse reactions, usually not differing in type and frequency from those that occur with placebo. Currently, there are a large number of generics of montelukast, therefore, practitioners have many questions regarding the benefits and risks of montelukast therapy for patients with BA and AR. In 2020 FDA (Food and Drug Administration USA) analyzed the risk of adverse events during Montelukast treatment and indicated them on the packaging of the drug (original montelukast and its generics). This contributed to the creation of an expert commission to study this issue and form an expert opinion, which is demonstrated in our publication.
The article is based on the resolution of the Expert Council, including experts from Russian Association of Allergists and Clinical Immunologists (RAACI) and Russian Respiratory Society (RRS) dated November 20, 2016, and the review of clinical studies results and publications on the biomarker-based diagnosis and biological treatment of severe uncontrolled asthma. The aim of this work is to develop a phenotype-oriented algorithm of diagnostics and treatment of severe asthma, supported by the biomarker testing for subsequent selection of appropriate immunobiological treatment. The article constitutes the summary of results of clinical studies and expert opinions on the treatment of asthma in patients who do not achieve disease control with standard treatment regimens including high doses of inhaled corticosteroids in the combination with long-acting beta-agonists, tiotropium, and medications from other pharmacological groups according to Russian Respiratory Society (2016) and GINA (2016-2017) guidelines. The article summarizes the results of international randomized clinical studies performed to assess safety and efficacy of new class of biological treatments, monoclonal antibodies acting against major cytokines that are responsible for inflammation, in patients with severe asthma, including a new anti-IL-5 antibody, reslizumab (Cinqaero).
