Aim To study the effect of regular drug therapy for cardiovascular and other diseases preceding the COVID-19 infection on severity and outcome of COVID-19 based on data of the ACTIVE (Analysis of dynamics of Comorbidities in paTIents who surVived SARS-CoV-2 infEction) registry.Material and methods The ACTIVE registry was created at the initiative of the Eurasian Association of Therapists. The registry includes 5 808 male and female patients diagnosed with COVID-19 treated in a hospital or at home with a due protection of patients’ privacy (data of nasal and throat smears; antibody titer; typical CT imaging features). The register territory included 7 countries: the Russian Federation, the Republic of Armenia, the Republic of Belarus, the Republic of Kazakhstan, the Kyrgyz Republic, the Republic of Moldova, and the Republic of Uzbekistan. The registry design: a closed, multicenter registry with two nonoverlapping arms (outpatient arm and in-patient arm). The registry scheduled 6 visits, 3 in-person visits during the acute period and 3 virtual visits (telephone calls) at 3, 6, and 12 mos. Patient enrollment started on June 29, 2020 and was completed on October 29, 2020. The registry completion is scheduled for October 29, 2022. The registry ID: ClinicalTrials.gov: NCT04492384. In this fragment of the study of registry data, the work group analyzed the effect of therapy for comorbidities at baseline on severity and outcomes of the novel coronavirus infection. The study population included only the patients who took their medicines on a regular basis while the comparison population consisted of noncompliant patients (irregular drug intake or not taking drugs at all despite indications for the treatment).ResultsThe analysis of the ACTIVE registry database included 5808 patients. The vast majority of patients with COVID-19 had comorbidities with prevalence of cardiovascular diseases. Medicines used for the treatment of COVID-19 comorbidities influenced the course of the infectious disease in different ways. A lower risk of fatal outcome was associated with the statin treatment in patients with ischemic heart disease (IHD); with angiotensin-converting enzyme inhibitors (ACEI)/angiotensin receptor antagonists and with beta-blockers in patients with IHD, arterial hypertension, chronic heart failure (CHF), and atrial fibrillation; with oral anticoagulants (OAC), primarily direct OAC, clopidogrel/prasugrel/ticagrelor in patients with IHD; with oral antihyperglycemic therapy in patients with type 2 diabetes mellitus (DM); and with long-acting insulins in patients with type 1 DM. A higher risk of fatal outcome was associated with the spironolactone treatment in patients with CHF and with inhaled corticosteroids (iCS) in patients with chronic obstructive pulmonary disease (COPD).Conclusion In the epoch of COVID-19 pandemic, a lower risk of severe course of the coronavirus infection was observed for patients with chronic noninfectious comorbidities highly compliant with the base treatment of the comorbidity.

Primary immunodeficiency is a rare congenital pathology associated with failure of immune system, manifested by disturbances of its functions. These defects lead to increased susceptibility of patients to various infectious agents, as well as the development of autoimmune, malignant and other diseases. Primary immunodeficiency is classified as a rare disease, which was previously associated with a poor prognosis with a high risk of mortality in childhood. To date, the emergence of highly effective treatment methods has changed the course and prognosis of these diseases. Clinicians of various specialties increasingly meet with this pathology in everyday practice, including adult age cohorts. In this regard, early diagnosis of primary immunodeficiency in adults becomes relevant, being associated with choosing optimal therapy, prevention of severe internal organ damage, determination of management strategy for the patient, as well as the need to identify inherited disorders and provide information to the patient’s family. Delayed verification of the diagnosis may cause disability of the patient and development of irreversible, often fatal complications. This article presents our own clinical case with a newly diagnosed clinical condition: Common variable immunodeficiency disorder (CVID), the most common form of primary immunodeficiency in adults. The symptoms of common variable immunodeficiency disorder appear in these patients in adulthood, but a high-quality collected history of the disease will allow you to trace symptoms in the patients even since early childhood. There is a common gap for several years between the onset of the disease and clinical diagnosis, since erroneous diagnosis is often made due to non-specific clinical symptoms that resemble other, more frequent diseases. The prognosis of patients with CVID depends on several factors: frequency of infections, structural disorders in the lungs, the occurrence of autoimmune diseases and the success of infection prevention. Thus, a variety of clinical forms of primary immunodeficiency, lack of awareness of doctors about this pathology, complexity of immunological examination in the general medical network lead to the fact that CVID is not diagnosed for long terms, and patients do not receive the necessary pathogenetic therapy. There is a need for drawing attention of doctors of various disciplines to the fact that the recurrent inflammatory processes of various localization, which are difficult to respond to adequate traditional therapy, may be caused by changes in the immune system, including congenital, genetically determined immunodeficiency.

Asthma is one of the most common and socially significant human diseases. To date, spirometry is included in most recommendations as the gold standard for the diagnosis of obstructive disorders. However, in real clinical practice, this procedure does not always reveal signs of bronchial obstruction, not only in the early stages of the disease but also in more severe controlled bronchial asthma. Tests of oscillatory mechanics are increasingly being used to detect early violations of the pulmonary ventilation function. These tests are based on the forced oscillation technique, and the latest modification is impulse oscillometry system. Theaimof this study was to investigate the capabilities of impulse oscillometry in diagnosing early changes in the function of the respiratory system in patients with asthma and identifying the most informative parameters of the method.Methods. A total of 146 patients with an established diagnosis of mild and moderate asthma were examined during remission. The patients were divided into 2 groups by the severity of asthma. The comparison group included 40 people with no signs of lung abnormalities.Results. Disorders of the pulmonary ventilation function were found in 23% of patients with asthma by spirometry, in 42% by bodypletismography in 42%, and in 72% of patients by impulse oscillometry. Impulse oscillometry system revealed obstructive changes localized in the central respiratory tract in 11% of patients, and obstruction of mixed localization was found in 6% of respondents. Peripheral respiratory tract disorders were diagnosed in 56 % of patients. Most respiratory tract lesions were located in the small bronchi in both groups. The obstructive disorders in large bronchi and generalized obstruction were observed more often in the 2ndgroup. Among impulse oscillometry parameters, the increase in Delta (Rrs5– Rrs20) was most often recorded in both examined groups of patients with asthma.Conclusion. Compared to standard methods, impulse oscillometry system is more sensitive. Therefore, it has advantages in diagnosing respiratory system dysfunctions both in the early stages of asthma and in more severe cases during remission.

The international AKTIV register presents a detailed description of out- and inpatients with COVID-19 in the Eurasian region. It was found that hospitalized patients had more comorbidities. In addition, these patients were older and there were more men than among outpatients. Among the traditional risk factors, obesity and hypertension had a significant negative effect on prognosis, which was more significant for patients 60 years of age and older. Among comorbidities, CVDs had the maximum negative effect on prognosis, and this effect was more significant for patients 60 years of age and older. Among other comorbidities, type 2 and 1 diabetes, chronic kidney disease, chronic obstructive pulmonary disease, cancer and anemia had a negative impact on the prognosis. This effect was also more significant (with the exception of type 1 diabetes) for patients 60 years and older. The death risk in patients with COVID-19 depended on the severity and type of multimorbidity. Clusters of diseases typical for deceased patients were identified and their impact on prognosis was determined. The most unfavorable was a cluster of 4 diseases, including hypertension, coronary artery disease, heart failure, and diabetes mellitus. The data obtained should be taken into account when planning measures for prevention (vaccination priority groups), treatment and rehabilitation of COVID-19 survivors.

This review highlights fundamental knowledge about the processes within a damaged liver cell, mechanisms of fi bro- and angiogenesis, as well as hypoxia and hypoxemia. Th e causes and consequences of endothelial dysfunction, the role of cytokines in vascular remodeling and the formation of hemodynamic disorders are described. Th ese changes lead to disorder of local and systemic hemodynamics in case of liver cirrhosis. Such complications as: hepatopulmonary syndrome and portopulmonary hypertension are also described.

The article presents a case of granulomatosis with polyangiitis, which is difficult for clinical diagnosis. Recently, the incidence of systemic vasculitis has increased, and given the similarity of clinical symptoms with other pathologies, a doctor of any specialty should carry out differential diagnosis. Granulomatosis with polyangiitis is characterized mainly by damage to the upper respiratory tract, lungs, and kidneys. The main method for diagnosing granulomatosis with polyangiitis is biopsy with histological examination, which allows to detect inflammation in the affected tissues. A feature of granulomatosis with polyangiitis is detection of antineutrophil cytoplasmic antibodies in the blood serum. However, these antibodies are recorded only in 80% of patients and are not detected in the remission phase, which makes diagnosis much more difficult.

The organizer of the registers “Dynamics analysis of comorbidities in SARSCoV-2 survivors” (AKTIV) and “Analysis of hospitalizations of comorbid patients infected during the second wave of SARS-CoV-2 outbreak” (AKTIV 2) is the Eurasian Association of Therapists (EAT). Currently, there are no clinical registries in the Eurasian region designed to collect and analyze information on long-term outcomes of COVID-19 survivors with comorbid conditions. The aim of the register is to assess the impact of a novel coronavirus infection on long-term course of chronic non-communicable diseases 3, 6, 12 months after recovery, as well as to obtain information on the effect of comorbidity on the severity of COVID-19. Analysis of hospitalized patients of a possible second wave is planned for register “AKTIV 2”. To achieve this goal, the register will include men and women over 18 years of age diagnosed with COVID-19 who are treated in a hospital or in outpatient basis. The register includes 25 centers in 5 federal districts of the Russian Federation, centers in the Republic of Armenia, the Republic of Kazakhstan, the Republic of Kyrgyzstan, the Republic of Belarus, the Republic of Moldova, and the Republic of Uzbekistan. The estimated capacity of the register is 5400 patients.

Aim. To study the clinical course specifics of coronavirus disease 2019 (COVID-19) and comorbid conditions in COVID-19 survivors 3, 6, 12 months after recovery in the Eurasian region according to the AKTIV register. Material and methods.The AKTIV register was created at the initiative of the Eurasian Association of Therapists. The AKTIV register is divided into 2 parts: AKTIV 1 and AKTIV 2. The AKTIV 1 register currently includes 6300 patients, while in AKTIV 2 — 2770. Patients diagnosed with COVID-19 receiving in- and outpatient treatment have been anonymously included on the registry. The following 7 countries participated in the register: Russian Federation, Republic of Armenia, Republic of Belarus, Republic of Kazakhstan, Kyrgyz Republic, Republic of Moldova, Republic of Uzbekistan. This closed multicenter register with two nonoverlapping branches (in- and outpatient branch) provides 6 visits: 3 in-person visits during the acute period and 3 telephone calls after 3, 6, 12 months. Subject recruitment lasted from June 29, 2020 to October 29, 2020. Register will end on October 29, 2022. A total of 9 fragmentary analyzes of the registry data are planned. This fragment of the study presents the results of the post-hospitalization period in COVID-19 survivors after 3 and 6 months. Results. According to the AKTIV register, patients after COVID-19 are characterized by long-term persistent symptoms and frequent seeking for unscheduled medical care, including rehospitalizations. The most common causes of unplanned medical care are uncontrolled hypertension (HTN) and chronic coronary artery disease (CAD) and/or decompensated type 2 diabetes (T2D). During 3- and 6-month follow-up after hospitalization, 5,6% and 6,4% of patients were diagnosed with other diseases, which were more often presented by HTN, T2D, and CAD. The mortality rate of patients in the post-hospitalization period was 1,9% in the first 3 months and 0,2% for 4-6 months. The highest mortality rate was observed in the first 3 months in the group of patients with class II-IV heart failure, as well as in patients with cardiovascular diseases and cancer. In the pattern of death causes in the post-hospitalization period, following cardiovascular causes prevailed (31,8%): acute coronary syndrome, stroke, acute heart failure. Conclusion. According to the AKTIV register, the health status of patients after COVID-19 in a serious challenge for healthcare system, which requires planning adequate health system capacity to provide care to patients with COVID-19 in both acute and post-hospitalization period.

Aim. To determine the level of IgA and IgG to estradiol, progesterone, and benzo[a]pyrene in women with or without preterm labor and to assess whether the administration of progestagens affect these parameters.Aim. To assess the immunological parameters in severe bronchial asthma in relation to the phenotype and endotype of inflammation.Materials and Methods. We examined 40 patients with severe bronchial asthma, further stratified by phenotype (allergic asthma and fixed airflow obstruction asthma) and 17 healthy volunteers. Bronchial obstruction was clinically estimated by the day/night asthma attack count or number of β2-agonists inhalations per day. The number of CD4+, CD3+, CD19+, CD8+, CD3+, HLADR+, CD45RA+, CD4+, CD3+, CD16+, and CD56+ lymphocytes was determined using flow cytometry. Measurement of serum IL-4 and IL-5 was performed by enzyme-linked immunosorbent assay.Results. Patients with severe bronchial asthma showed an increase in naive T-lymphocytes and HLA-DR+ lymphocytes in comparison with healthy blood donors. In addition, an increase in serum of IL-4 and total IgE was found in patients with asthma. Patients with severe bronchial asthma and > 300 eosinophils/pL were characterised by an increase in CD4+ lymphocytes, NK (CD16+CD56+) cells, and higher ratio of CD4+ to CD8+ T-lympho-cytes.Conclusion. Further research on asthma development should be focused on the role of NK cells in the inflammation and their association with eosinophils.

COVID-19 is a severe infection with high mortality. The concept of the disease has been shaped to a greater extent on the basis of large registers from the USA, Spain, Italy, and China. However, there is no information on the disease characteristics in Caucasian patients.Therefore, we created an international register with the estimated capacity of 5,000 patients — Dynamics Analysis of Comorbidities in SARS-CoV-2 Survivors (AKTIV SARS-CoV-2), which brought together professionals from the Russian Federation, Republic of Armenia, Republic of Kazakhstan, and Kyrgyz Republic. The article presents the first analysis of the register involving 1,003 patients. It was shown that the most significant difference of the Caucasian population was the higher effect of multimorbidity on the mortality risk vs other registers. More pronounced effect on mortality of such diseases as diabetes, obesity, hypertension, chronic kidney disease, and age over 60 years was also revealed.

Introducrion. Due to the peculiarities of the Krasnoyarsk krai (a huge territory, low population density, different levels of health development in the districts, personnel shortage), there is a need to increase the availability and quality of medical care to district patients. For this purpose, since 2016, the Regional telemedicine system has started functioning online monitoring for patients with severe pneumonia, which provides full-fledged curation of patients from all over the region.Objective. To evaluate the results of RTS monitoring of patients with severe pneumonia.Materials and methods. 770 cases of severe community-acquired pneumonia registered in RTS from 2016 to 2018 were analyzed. Statistical data processing was performed using variational statistics using the “Excel-7” software package. For all values, the minimum significance level (p) of 0.05 was taken into account.Results. The risk factor for severe flow was male. Among comorbid diseases, cardiovascular and bronchopulmonary diseases, diabetes, alcoholism and HIV infection prevailed. The lack of flu vaccination in 97% of patients increased the number of deaths by 4.5 times. The greatest need for consultation arose in the Central district hospitals of low capacity. The majority of patients are registered in the system on the first day of hospitalization and are consulted by a pulmonologist of the Regional clinical hospital within 2 hours. Air ambulance of the Regional clinical hospital evacuated 174 patients, the need for flights decreased by 3.5 times. The main mistakes of district hospitals in the management of patients were the irrational selection of antibacterial drugs, the volume of detoxification therapy, the late start of antiviral therapy and ventilators, and the lack of prescription of anticoagulants.Conclusions. Along with the presence of comorbidities, the outcome of the EAP is affected by the quality of medical care, which depends on the professional training of medical workers, continuity in the work of regional medical institutions and air ambulance, which causes difficulties, given the specifics of the region. RTS allows you to solve this problem at minimal cost.
