Abstract
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.gov Identifier: NCT05069649).
Aim. To evaluate the efficacy and safety of the use of Ergoferon for the non-specific prevention of COVID-19 during vaccination against a new coronavirus infection.
Materials and methods. From October 2021 to April 2022, 1,057 patients aged 18 to 92 years who received component I of the Gam-COVID-Vac vaccine were included. After screening, 1,050 patients were randomized into 2 groups: 526 people received Ergoferon according to the prophylactic scheme 1 tablet per administration 2 times a day for 3 weeks, the drug is not allowed during the meal and should be kept in the mouth without swallowing, until completely dissolved; 524 patients received a placebo according to the Ergoferon scheme. The total duration of participation in the study was 5 weeks + 3 days. The primary endpoint is the number of RT-PCR confirmed cases of SARS-CoV-2 infection, regardless of the presence of symptoms during participation in the study. An additional criterion of effectiveness is the proportion of those hospitalized with COVID-19. The safety assessment included consideration of the presence and nature of adverse events (AEs), their severity, relationship with the drug intake, and outcome. Statistical data processing was carried out using SAS 9.4 with the calculation of the exact Fisher test, 2 test, CochraneMantelHensel test, Wilcoxon test and other parameters.
Results. The ITT (Intention-to-treat) and PP [Per Protocol] efficacy analysis included data from 1,050 [970] patients: 526 [489] people Ergoferon group and 524 [481] people Placebo group. The primary endpoint the number of laboratory-confirmed cases of SARS-CoV-2 infections was 3 times less compared to placebo 7 (1.43%) vs 22 (4.57%), respectively (p=0.0046; [p=0.0041]). Taking Ergoferon reduces the risk of SARS-CoV-2 infection by more than 3 times in vaccinated patients during 5 weeks of the vaccination and post-vaccination periods (p=0.0046 [p=0.0041]). Of the COVID-19 patients in the Ergoferon group (1.33%) nobody was hospitalized. According to the Post hoc analysis, Ergoferon reduces the risk of COVID-19 disease by 4 times in the period between the components I and II of the Gam-COVID-Vac vaccine (p=0.0066 [p=0.006]). The frequency of AEs in both groups did not differ. There were no registered AEs associated with the drug with a reliable degree. There was a high level of patient compliance and good tolerability.
Conclusion. Ergoferon is an effective and safe drug for the prevention of COVID-19 in people vaccinated against a new coronavirus infection.

Uncovering the genetic links of SARS-CoV-2 infections on heart failure co-morbidity by a systems biology approach. ESC Heart Fail 2022; 9:2937-2954. [PMID: 35727093 PMCID: PMC9349450 DOI: 10.1002/ehf2.14003] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 04/24/2022] [Accepted: 05/19/2022] [Indexed: 01/08/2023] Open
Abstract
Aims The co‐morbidities contribute to the inferior prognosis of COVID‐19 patients. Recent reports suggested that the higher co‐morbidity rate between COVID‐19 and heart failure (HF) leads to increased mortality. However, the common pathogenic mechanism between them remained elusive. Here, we aimed to reveal underlying molecule mechanisms and genetic correlation between COVID‐19 and HF, providing a new perspective on current clinical management for patients with co‐morbidity. Methods The gene expression profiles of HF (GSE26887) and COVID‐19 (GSE147507) were retrieved from the GEO database. After identifying the common differentially expressed genes (|log2FC| > 1 and adjusted P < 0.05), integrated analyses were performed, namely, enrichment analyses, protein–protein interaction network, module construction, critical gene identification, and functional co‐expression analysis. The performance of critical genes was validation combining hierarchical clustering, correlation, and principal component analysis in external datasets (GSE164805 and GSE9128). Potential transcription factors and miRNAs were obtained from the JASPER and RegNetwork repository used to construct co‐regulatory networks. The candidate drug compounds in potential genetic link targets were further identified using the DSigDB database. Results The alteration of 12 genes was identified as a shared transcriptional signature, with the role of immune inflammatory pathway, especially Toll‐like receptor, NF‐kappa B, chemokine, and interleukin‐related pathways that primarily emphasized in response to SARS‐CoV‐2 complicated with HF. Top 10 critical genes (TLR4, TLR2, CXCL8, IL10, STAT3, IL1B, TLR1, TP53, CCL20, and CXCL10) were identified from protein–protein interaction with topological algorithms. The unhealthy microbiota status and gut–heart axis in co‐morbidity were identified as potential disease roads in bridging pathogenic mechanism, and lipopolysaccharide acts as a potential marker for monitoring HF during COVID‐19. For transcriptional and post‐transcriptional levels, regulation networks tightly coupling with both disorders were constructed, and significant regulator signatures with high interaction degree, especially FOXC1, STAT3, NF‐κB1, miR‐181, and miR‐520, were detected to regulate common differentially expressed genes. According to genetic links targets, glutathione‐based antioxidant strategy combined with muramyl dipeptide‐based microbe‐derived immunostimulatory therapies was identified as promising anti‐COVID‐19 and anti‐HF therapeutics. Conclusions This study identified shared transcriptomic and corresponding regulatory signatures as emerging therapeutic targets and detected a set of pharmacologic agents targeting genetic links. Our findings provided new insights for underlying pathogenic mechanisms between COVID‐19 and HF.
