One of the most common chronic upper respiratory diseases worldwide is allergic rhinitis (AR). Despite advances in understanding the mechanisms of allergic inflammation, the symptoms of AR in most cases are not completely controlled by modern treatment methods. Allergic rhinitis is a precursor and predisposing factor for the development of other respiratory diseases, one of which is asthma. Diagnosis of AR is being actively conducted, but there is still a serious problem of uncontrolled and chaotic treatment of patients, so it is necessary to provide comprehensive medical care within the national health system. ARIA aims to develop and apply internationally recommendations for the management of patients with allergic respiratory diseases. In collaboration with other international associations that deal with the treatment and diagnosis of allergies and respiratory diseases, regulations and programs have been developed for the treatment of patients with AR, as well as when it is combined with asthma, which form the basis of ARIA. This document has been adapted for use in the field of healthcare in the Russian Federation and covers key issues related to the management of patients with AR and in combination with AR and asthma.

Anaphylactic shock is a severe life-threatening reaction, that may be caused by medicines, food, hymenoptera and animal poisons, etc. Therefore, anaphylactic shock (anaphylaxis) can develop both in a medical institution and outside it, and physicians of any specialties should be ready to treat this condition. In this regard, clinical guidelines for anaphylactic shock have been developed. These recommendations were approved by the Russian Association of Allergy and Clinical Immunology (Protocol No. 743/12 dated December 30, 2020) and the Federation of Anesthesiologists and Resuscitators (Protocol No. 1 dated January 13, 2021), approved at a meeting of the Scientific and Practical Council of the Ministry of Health of the Russian Federation (Protocol No. .2020 No. 743/12). The guidelines cover a number of nosologies that correspond to the codes of the International Statistical Classification of Diseases and Related Health Problems: T 78.0; T 78.2; T 80.5; T 88.6. The clinical guidelines systematize modern data on etiology, epidemiology, classification, clinical picture, diagnosis, treatment and prevention of anaphylactic shock. An algorithm for managing a patient with anaphylactic shock has been developed. Clinical guidelines for anaphylactic shock are intended for practitioners of all specialties, students and teachers of medical universities, residents, graduate students.

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.
