Up-to-date data on patients with chronic obstructive pulmonary disease (COPD) in the Russian Federation are necessary to improve medical care effectiveness.This article presents the results of the retrospective part and the cross-sectional assessment of the CORSAIR study, which aimed to assess the distribution of COPD patients in the Russian population by symptom severity and exacerbation risk as per GOLD (2020) classification groups A, B, C, D.Methods. The observational multicenter study CORSAIR included a cross-sectional assessment with data collection during the previous 12 months (retrospective part) and subsequent follow-up for 12 months (prospective part). Data from 704 patients obtained at 18 study sites from August 2021 to November 2022 are presented. At the first visit, the physician recorded medical history, clinical data on the disease course, and COPD therapy, assessed compliance of treatment with national guidelines, and determined whether treatment change was needed considering the predominant treatable trait (dyspnea or exacerbation).Results. Upon inclusion, most patients had severe COPD symptoms (mMRC score ≥ 2; САТ score ≥ 10) and severe and very severe airflow obstruction (GOLD III and GOLD IV; FEV1 < 50% оf predicted). More than half of the patients had at least one moderate or severe COPD exacerbation within the previous 12 months. As per the GOLD (2020) classification, 57.2% of patients belonged to Group B (severe symptoms and low risk of exacerbations) and 30.3% to Group D (severe symptoms and high risk of exacerbations). 58.8% of patients received treatment that was not compliant with national clinical guidelines in force at the study initiation. 31.7% of patients had not COPD control. Blood eosinophil count was above 300 cells/μL in 15.1% of patients.Conclusion. In most cases, patients had severe COPD symptoms with frequent exacerbations, and the prescribed treatment did not comply with national clinical guidelines. These data will be analyzed alongside the prospective study results.

Aim. To establish the relationship between lipid profile parameters, coagulation system and inflammation markers in patients with hypertension (HTN) and multifocal atherosclerosis (MFA).Material and methods. The study included 110 patients with HTN and MFA with a median age of 59 (51,0;64,3) years. Of these, 15 patients achieved target lowdensity lipoprotein cholesterol (LDL-C) 1,8 mmol/l (group 2). Patients in both groups received lipid-l owering and comparable antihypertensive, antiplatelet therapy. To identify coagulation disorders, a test was performed on the T-2 Thrombodynamics Analyser System (OOO GemaCor, Moscow, Russia). All study participants were assessed for levels of high-sensitivity C-reactive protein and interleukin-6.Results. Despite the lipid-l owering therapy, most patients with HTN and MFA (86,4%) did not achieve target LDL-C <1,8 mmol/l. In patients of group 2, compared to group 1, more pronounced procoagulant shifts were noted. The clot growth rate and the permanent clot growth rate were shifted to the hypercoagulation (28,6 μm/min vs 27 μm/min). Correlations between the studied parameters were also revealed. In group 1, the LDL-C level had a moderate direct correlation with the initial clot growth rate (r1=0,54, p1=0,04) and clot density (r1=0,55, p1=0,03), while in group 2, the concentrations of total cholesterol and LDL-C correlated with clot growth delay (r2=-0,22, p2=0,03 and r2=-0,21, p2=0,04, respectively).Conclusion. In patients with HTN and MFA, complex relationships between lipid parameters, coagulation parameters, and inflammatory markers are observed, especially in the group with unachieved lipid target levels. Extra efforts are needed to identify patients with HTN and MFA in clinical practice and to prescribe optimal lipid-lowering therapy. In addition to lipid parameters, correction of other disorders (hemostasis, inflammation) that may affect the prognosis is necessary.

Цель. Оценить влияние субклинической нефропатии на показатели качества жизни пациентов с СД 2 типа и сердечно-сосудистыми заболеваниями.Материалы и методы. Обследовано 86 больных с СД 2 типа и сердечно-сосудистыми заболеваниями. Обследование пациентов проводилось 2-х кратно с интервалом в 12 месяцев. Сформировано 2 группы пациентов: группа 1 – пациенты с впервые выявленными маркерами повреждения почек (n=28); группа 2 – без маркеров повреждения почек (n=58). Для оценки качества жизни использована русифицированная версия опросника EQ-5D.Статистическая обработка результатов проводилась с использованием компьютерной программы Statistica for Windows 6.0 (StatSoft Inc., США).Результаты. Сравниваемые группы на момент включения по параметрам КЖ не различались. У пациентов, отнесенных к группе 1, оценка в баллах качество жизни по аналоговой шкале была выше группы 2.Через 12 месяцев в группе 1 не выявлено динамики баллов по визуальной аналоговой шкале, выявлена отрицательная девиация составляющих качества жизни; в группе 2 статистически значимо улучшилась оценка в баллах по визуально-аналоговой шкале. В группе 1 выявлена большая доля лиц, у которых были снижены показатели, характеризующие физическую составляющую качества жизни. Напротив, в группе 2 улучшилось качество жизни и по физическим, и психоэмоциональным компонентам. Таким образом, у пациентов с признаками субклинической нефропатии выявилось ее негативное влияние на компоненты качества жизни.Заключение. Появление признаков дисфункции почек у больных с СД 2 типа и сердечно-сосудистыми заболеваниями ассоциируется со снижением качества жизни. Полученные данные подчеркивают важность профилактики развития дисфункции почек, коррекцию факторов риска и прогрессирования нефропатии.
