Бронхиальная астма и COVID-19: обзор рекомендаций по ведению пациентов с бронхиальной астмой во время пандемии COVID-19

The emergence of a new disease COVID-19 (coronavirus disease 2019), caused by the coronavirus named SARS-CoV-2, has significantly changed the usual interaction pattern between a doctor and a patient. Previous large studies have identified risk factors for a severe course of COVID-19, including old age, hypertension, diabetes, cardiovascular diseases, and chronic obstructive pulmonary disease. However, asthma and respiratory allergy have not been identified as risk factors for the severe disease. These factors give clues to the pathogenesis of COVID-19, approaches to the controller medications, target therapy, allergen-specific immunotherapy (ASIT) in patients with various phenotypes and endotypes of asthma during the pandemic.The purpose of this review is to summarize the currently available knowledge about SARS-CoV-2, T2-endotype of asthma, eosinophilic inflammation. The article provides an overview of the data from studies of COVID-19 patients with asthma, the main recommendations of the Global Initiative for Asthma (2021) and the Ministry of Health of the Russian Federation. It shows that targeting the endotypes and phenotypes of asthma can influence the management of COVID-19 patients with asthma. The influence of the imbalance of the immune system, pro-inflammatory cytokines, and effector cells in patients with asthma on the development and progression of COVID-19 is considered. Recommendations are given for the controller medications, targeted therapy, allergen-specific immunotherapy during the pandemic.Conclusion. The current recommendations for asthma treatment, based on the latest research of COVID-19, deepen our understanding of the course of COVID-19 in patients with different phenotypes and endotypes of asthma, approaches to traditional methods of treating asthma according to clinical guidelines during the pandemic.При появлении нового заболевания COVID-19 (COronaVIrus Disease–2019), вызванного коронавирусом SARS-CoV-2, значительно изменилась привычная схема взаимодействия врача и пациента. По данным крупных исследований выявлен ряд факторов риска развития тяжелого течения заболевания COVID-19 – пожилой возраст, гипертония, сахарный диабет, сердечно-сосудистые заболевания, хроническая обструктивня болезнь легких. Однако бронхиальная астма (БА) и респираторная аллергия не идентифицированы как существенные факторы риска тяжелого течения заболевания, а выявление этих факторов дает важную информацию о патогенезе COVID-19, подходах к базисной, таргетной и аллерген-специфической терапии (АСИТ) в условиях пандемии при различных фенотипах и эндотипах БА.Целью обзора явилось обобщение имеющихся в настоящее время знаний о SARS‐CoV‐2, Т2-эндотипе БА, эозинофильном воспалении. Представлены данные исследований по изучению особенностей течения COVID-19 у пациентов с БА, основные рекомендации Глобальной инициативы по БА (Global Initiative for Asthma – GINA, 2021) и Министерства здравоохранения Российской Федерации. Показано, что ориентирование на эндотипы и фенотипы БА способствует выбору оптимальной тактики ведения пациентов с COVID-19 и БА. Рассмотрено влияние дисбаланса иммунной системы, провоспалительных цитокинов, эффекторных клеток у больных БА на развитие и прогрессирование COVID-19. Приведены рекомендации по ведению пациентов препаратами базисной, таргетной терапии, АСИТ в условиях пандемии.Заключение. Текущие рекомендации по лечению БА, основанные на результатах последних исследований, в контексте c COVID-19 углубляют понимание особенностей течения коорновирусной болезни у пациентов с различными фенотипами и эндотипами БА и подходов к традиционным методам ее лечения согласно клиническим рекомендациям в условиях пандемии

Pilot Project «All-Russian Registry of Patients with Severe Bronchial Asthma.» The First Results in a Children’s Group of Patients (Moscow’s Observation Program)

The article presents the first results of the pilot observation program «The All-Russian Severe Asthma Patient Registry» which was started in Moscow. Objectives. The objective of this initiative is the accumulation of clinical data on patients with severe bronchial asthma in the Russian Federation. Methods. The chosen method was a registry, the rights holders of which were 3 professional associations — Interregional Public Organization «Russian Respiratory Society», Public Organization «Union of Pediatricians of Russia», All-Russian Public Organization «Association of Allergologists and Clinical Immunologists». Results. The results of the pilot project are presented by the data analysis of electronic case report forms of 36 children (totally, the project included 100 patients, 64 adults and 36 children) enrolled in the program from June to December 2016. Using the registry, a detailed analysis of the clinical characteristics of a group of children with severe atopic bronchial asthma was carried out, the results of a pharmacoepidemiological evaluation of therapy were given. Obtained by the researchers, a high frequency of the assignment of a genetically engineered biologic drug of omalizumab meets the international recommendations but does not reflect the all-Russian reality and can be explained by inclusion in the registry of pediatric patients observed only in the Federal State Autonomous Institution «National Scientific and Practical Center of Children’s Health» of the Ministry of Health of the Russian Federation. Conclusion. To determine true indicators that characterize bronchial asthma in children in the Russian Federation it is necessary, undoubtedly, to expand the geography of project participants

Assessment of physicians’ and senior medical students’ knowledge in treatment of patients with community acquired pneumonia: Current results of the KNOCAP project

Introduction. Community-acquired pneumonia (CAP) remains one of the most acute problems of bronchopulmonary pathology being the 4th in the mortality structure (after cardiovascular, cerebrovascular diseases and malignant neoplasms) and the 1st among all fatalities from infectious diseases. Thanks to the scientific progress achieved in the antibiotic therapy and vaccine prophylaxis, the death toll has decreased four times compared to its rate during the “pre-antibiotic era“. However, nowadays there is a steadily increasing trend in the pneumonia mortality rate in Russia. The only possible way to increase efficacy of CAP treatment is timely initiated rational antibiotic therapy, considering the possible etiologies, risk factors and the severity of the patient’s condition. Materials and methods. The article represents the results of anonymous prospective surveys within the framework of the KNOCAP multi-centered research project aimed at accessing the knowledge on the fundamental issues in diagnosis and treatment of community-acquired pneumonia. The survey involved 222 students in their fifth- and sixth years in medical institute from Belgorod, Dnepr (Dnipro), Voronezh, Kiev (Kyiv) and Saratov and 110 physicians from Krasnodar, Saratov, Belgorod and Dnepr.Results and discussion. According to the results of the survey, such levels of correct answers were given by doctors and students, respectively: the inadmissibility of antimicrobial therapy (AMT) delay in CAP - 82% and 59%; the main criterion for withholding AMT - 56% and 37%; “sequential therapy” - 61% and 59%. At the same time, only 24% of the students and 23% of the physicians surveyed correctly reported typical mistakes in the treatment of a non-severe CAP with 50% or more accuracy; and in case of initial treatment, the number of correct responses was less than 28% for students and 45% for doctors. Conclusion. The survey showed that both senior medical students majoring in Medical Care and general practitioners had a low level of knowledge in CAP treatment. Hence, curricula need to be adjusted both in medical universities and in health institutions for practitioners in order to inform them and, thus, improve the quality of their knowledge in this field

Цель данной инициативы — аккумуляция клинических сведений о больных тяжелой бронхиальной астмой в Российской Федерации. Методы. Методом был выбран регистр, правообладателями которого стали 3 профессиональные ассоциации — Межрегиональная общественная организация «Российское респираторное общество», Общественная организация «Союз педиатров России», Всероссийская общественная организация «Ассоциация аллергологов и клинических иммунологов». Результаты пилотного проекта, представлены анализом данных электронных индивидуальных регистрационных карт 36 пациентов детского возраста (всего в проект было включено 100 больных, из них 64 взрослых и 36 детей), прошедших регистрацию в программе с июня по декабрь 2016 г. С использованием регистра проведен подробный анализ клинической характеристики группы детей с тяжелой атопической бронхиальной астмой, даны результаты фармакоэпидемиологической оценки терапии. Полученная исследователями высокая частота назначения генно- инженерного биологического препарата омализумаба соответствует международным рекомендациям, однако не отражает общероссийской действительности и может быть объяснена включением в регистр пациентов детского возраста, наблюдающихся только в ФГАУ «ННПЦЗД» Минздрава России. Заключение. Для определения истинных показателей, характеризующих бронхиальную астму у детей в Российской Федерации, несомненно, необходимо расширение географии участников проекта.

Canagliflozin and renal outcomes in type 2 diabetes and nephropathy

BACKGROUND Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium–glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to <90 ml per minute per 1.73 m2 of body-surface area and albuminuria (ratio of albumin [mg] to creatinine [g], >300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P=0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P<0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P=0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P=0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years

Kidney and Cardiovascular Effects of Canagliflozin According to Age and Sex: A Post Hoc Analysis of the CREDENCE Randomized Clinical Trial

Rationale & Objective: It is unclear whether the effect of canagliflozin on adverse kidney and cardiovascular events in those with diabetic kid-ney disease varies by age and sex. We assessed the effects of canagliflozin among age group categories and between sexes in the Canagli-flozin and Renal Endpoints in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) study.Study Design: Secondary analysis of a random-ized controlled trial. Setting & Participants: Participants in the CREDENCE trial. Intervention: Participants were randomly assigned to receive canagliflozin 100 mg/d or placebo.Outcomes: Primary composite outcome of kid-ney failure, doubling of serum creatinine con-centration, or death due to kidney or cardiovascular disease. Prespecified secondary and safety outcomes were also analyzed. Out-comes were evaluated by age at baseline (<60, 60-69, and >_70 years) and sex in the intention-to-treat population using Cox regression models.Results: The mean age of the cohort was 63.0 & PLUSMN; 9.2 years, and 34% were female. Older age and female sex were independently associ-ated with a lower risk of the composite of adverse kidney outcomes. There was no evidence that the effect of canagliflozin on the primary outcome (acomposite of kidney failure, a doubling of serum creatinine concentration, or death from kidney or cardiovascular causes) differed between age groups (HRs, 0.67 [95% CI, 0.52-0.87], 0.63 [0.4 8-0.82], and 0.89 [0.61-1.29] for ages <60, 60-69, and >_70 years, respectively; P = 0.3 for interaction) or sexes (HRs, 0.71 [95% CI, 0.5 4-0.95] and 0.69 [0.56-0.8 4] in women and men, respectively; P = 0.8 for interaction). No differences in safety outcomes by age group or sex were observed.Limitations: This was a post hoc analysis with multiple comparisons.Conclusions: Canagliflozin consistently reduced the relative risk of kidney events in people with diabetic kidney disease in both sexes and across age subgroups. As a result of greater background risk, the absolute reduction in adverse kidney outcomes was greater in younger participants.Funding: This post hoc analysis of the CREDENCE trial was not funded. The CREDENCE study was sponsored by Janssen Research and Development and was conducted collaboratively by the sponsor, an academic-led steering committee, and an academic research organization, George Clinical.Trial Registration: The original CREDENCE trial was registered at ClinicalTrials.gov with study number NCT02065791
