[The effect of etiopathogenetic therapy of COVID-19 on the severity of the disease: results of a multicenter double-blind placebo-controlled randomized trial].

Aim: The search for etiopathogenetic agents to prevent the development of severe and extremely severe COVID-19 remains relevant. A placebo-controlled randomized clinical trial was conducted to evaluate the efficacy and safety of the antibody-based biological drug (Raphamin).

Materials And Methods: 785 outpatients 18-75 y.

[Non-specific prevention of COVID-19 during vaccination against a new coronavirus infection: results of a multicenter, double-blind, placebo-controlled, randomized clinical trial].

Background: A multicenter, double-blind, placebo-controlled, randomized clinical trial (RCT) of the phase III efficacy and safety of Ergoferon for the non-specific prevention of COVID-19 during vaccination against a new coronavirus infection was conducted (permission of the Ministry of Health of the Russian Federation №559 dated 22.09.2021; ClinicalTrials.

The Efficacy and Safety of Gefapixant in a Phase 3b Trial of Patients with Recent-Onset Chronic Cough.

Purpose: We evaluated gefapixant, a P2X3 receptor antagonist, in participants with recent-onset (≤ 12 months) refractory chronic cough (RCC) or unexplained chronic cough (UCC).

Methods: Participants (≥ 18 years of age; ≥ 40 mm on a 100-mm cough severity visual analog scale [VAS] at screening and randomization) with chronic cough for < 12 months were enrolled in this phase 3b, double-blind, placebo-controlled, parallel group, multicenter study (NCT04193202). Participants were randomized 1:1 to gefapixant 45 mg BID or placebo for 12 weeks with a 2-week follow-up.

Efficacy and safety of the combined metabolic medication, containing inosine, nicotinamide, riboflavin and succinic acid, for the treatment of diabetic neuropathy: a multicenter randomized, double-blind, placebo-controlled parallel group clinical trial (CYLINDER).

Introduction: Antioxidants may have positive impact on diabetic polyneuropathy (DPN), presumably due to alleviation of oxidative stress. We aimed to evaluate the efficacy and safety of combination of antioxidants: succinic acid, inosine, nicotinamide, and riboflavin (SINR) in the treatment of DPN.

Research Design And Methods: In a double-blind, placebo-controlled clinical trial, men and women aged 45-74 years with type 2 diabetes and symptomatic DPN, with initial Total Symptom Score (TSS) ˃5, were randomized into experimental (n=109) or placebo (n=107) group.

Comparison of the Efficacy and Safety of Ketoprofen Plaster and Diclofenac Plaster for Osteoarthritis-Related Knee Pain: A Multicenter, Randomized, Active-Controlled, Open-Label, Parallel-Group, Phase III Clinical Trial.

Purpose: To compare the efficacy and safety of ketoprofen plasters and diclofenac plasters after 3 weeks of administration in patients with osteoarthritis-related knee pain.

Methods: This multicenter, randomized, active-controlled, open-label, parallel-group, noninferiority phase III study randomized 236 adults with osteoarthritis-related knee pain for 3 weeks with ketoprofen plaster 30 mg twice daily (n = 118) or diclofenac plaster 15 mg once daily (n = 118). The primary efficacy end point was the mean change from baseline to week 3 in the mean knee pain intensity score during walking, as measured by a 100-mm visual analog scale with a predefined noninferiority margin of 10.

[Indicators of the left ventricular-arterial coupling interaction in chronic forms of ischemic heart disease: relationships of the protradenomedullin and N-terminal probrain natriuretic peptide].

Purpose Of The Study: Analyze the parameters of the interaction between the left ventricle and the arterial system in patients with chronic forms of coronary heart disease and to identify relationships with levels of proadrenomedullin (MR‑proADM) and N‑terminal precursor of the brain natriuretic peptide B (NT‑proBNP).

Materials And Methods: 240 patients with chronic forms of coronary heart disease (median - 55,9 [43; 63] years) and Q‑forming myocardial infarction in the past were examined. Of these, 110 patients with myocardial infarction and preserved lef ventricular ejection fraction and 130 patients with ischemic cardiomyopathy.

[Circadian rhythms of thyroid hormones in patients with ischemic heart disease, arterial hypertension, and atrial fibrillation].

Aim: To evaluate the interrelationship between diurnal changes in thyrotropic hormone (TTH), free triiodothyronine (FT3), and clinical features of IHD in combination with AH and atrial fibrillation (AF).

Materials And Methods: Levels of TTH, FT3, and plasma cortisol were measured in 133 patients with IHD and AH with or without paroxysmal AF. The studied indexes included duration of IHD, AH, and AF; presence or absence of AF and AH; incidence rate of AF episodes per week; severity of exertional angina; systolic and diastolic BP; and EchoCG data.

Outcomes of endovascular thrombectomy with and without bridging thrombolysis for acute large vessel occlusion ischaemic stroke.

Background: Endovascular thrombectomy (EVT) for management of large vessel occlusion (LVO) acute ischaemic stroke is now current best practice.

Aim: To determine if bridging intravenous (i.v.

Suppression of hemopoiesis during CCl(4)-induced hepatic fibrosis: role of systemic endotoxemia.

CCl(4)-induced hepatic fibrosis in mice was accompanied by insufficiency of bone marrow myelo- and erythropoiesis. Polymyxin B completely abolished these changes. This phenomenon can be explained by the development of macrophage endotoxin tolerance during hepatic fibrosis.
