Bronchial asthma and chronic polypous rhinosinusitis are diseases associated with a T2-inflammatory immune response. These nosologies can be combined, creating the preconditions for a more severe course of multimorbidity, requiring the use of genetic engineering biological therapy. Dupilumab is a monoclonal antibody that can specifically bind to the alpha subunit of the interleukin-4 receptor and block the action of interleukins 4 and 13, which play a key role in the development of T2 inflammation. ⋯ The use of dupilumab in some cases may be accompanied by an increase in eosinophils in the blood. This article presents scientific base and our own experience in treating patients with dupilumab-associated eosinophilia, in addition we describe an algorithm for examining this group of patients for the purpose of timely diagnosis of diseases such as eosinophilic granulomatosis with polyangiitis, eosinophilic pneumonia, etc. It should be noted that in the most cases eosinophilia during targeted therapy with dupilumab is temporary and does not cause clinical manifestations.

Chronic obstructive pulmonary disease is now one of the most common noncommunicable diseases and the main causes of morbidity, disability and mortality in the world. In recent years, new approaches to epidemiology, diagnosis, classification (categorization), evaluation of phenotypes, as well as characterization and assessment of the severity of сhronic obstructive pulmonary disease exacerbations have emerged. ⋯ The use of non-medication methods (smoking cessation, physical activity and respiratory rehabilitation) and modern approaches to the treatment of respiratory failure and antibiotic therapy remain important. In terms of their significance, all these updates have a significant impact on real clinical practice and can be considered as a novel paradigm of the approaches to the diagnosis and management of this disease.

Review
[Pulmonary fibrosis after a new coronavirus infection - versions and controversies: A review].
Fibrosis is a dynamic process characterized by a typical cascade of events as a result of overexpressed repair of connective tissue in response to injury, and manifested by excessive accumulation of extracellular matrix. The development of fibrosis is a determining factor in the pathogenesis, clinical course and prognosis of many diseases, among which interstitial lung diseases occupy a special place. ⋯ Often, in the outcome of a coronavirus infection, patients retain clinical and functional changes that are similar to interstitial lung diseases of a different origin, the prognosis of which is determined by the development of interstitial fibrosis and the rate of its progression. This article is an attempt to consider topical issues of fibrogenesis in patients who have undergone a new coronavirus infection through the prism of polar data on immunobiology, clinical course and prognosis.

Randomized Controlled Trial Comparative Study
[Antibacterial therapy for acute streptococcal tonsillopharyngitis: results of a randomized comparative clinical trial with amoxicillin + clavulanic acid EXPRESS].
Acute tonsillopharyngitis is one of the most common types of respiratory tract infections. In case of bacterial etiologies of the disease, penicillin antibiotics are prescribed, in particular amoxicillin + clavulanic acid. Dispersible forms of antibiotics have a number of advantages over film-coated tablets and are characterized by better pharmacokinetic parameters that increase the effectiveness and safety of treatment, as well as patient compliance. ⋯ Amoxicillin + Clavulanic acid EXPRESS has high therapeutic efficacy in the treatment of acute streptococcal tonsillopharyngitis, comparable to the Amoxiclav in film-coated tablets. At the same time, dispersible tablets of Amoxicillin + Clavulanic acid EXPRESS demonstrated a significantly higher safety profile compared to the simple tablet form.

Comparative Study
[Differences in the elastic work of breathing of the pulmonary parenchyma in patients with bronchial asthma and COPD].
To determine and compare the work of breathing to overcome elastic resistance (Ael) in patients with bronchial asthma (BA) and chronic obstructive pulmonary disease (COPD) with similar changes in the elastic properties of the parenchyma in the same settings of ventilation disorders (grade 1). ⋯ In COPD patients, Ael was significantly increased (p>0.05), whereas in both BA groups, it was unchanged. Increased elastic work of breathing in patients with COPD may be associated with the involvement of certain types of contractile elements, which are preserved in patients with BA at the initial stages of the disease.
