ABSTRACT
The article is devoted to the global problems of modern medicine - HIV infection and the COVID-19 pandemic. The review of the literature highlights current ideas about the pathogenesis and course of COVID-19 in patients with HIV infection, and also touches upon the problems of concomitant pathology and mental health of patients with HIV in the setting of the COVID-19 pandemic. It has been shown that HIV-positive patients are a risk group for the severe course of COVID-19, in particular, individuals with severe immunodeficiency (CD4+ T lymphocytes 200 cells/l) due to the development of synergetic lung damage by SARS-CoV-2 and secondary infectious agents such as cytomegalovirus and Pneumocystis carinii. It has been proven that one of the targets of the SARS-CoV-2 virus is CD4+ T cells, which in COVID-19 leads to a more rapid progression of immunodeficiency in patients with HIV infection and, thus, significantly increases the risk of secondary diseases and death. Particular attention should be paid to middle-aged and elderly people living with HIV, who, compared with HIV-negative patients, are more likely to have concomitant pathology - arterial hypertension, cardiomyopathy and diabetes mellitus, which are the risk factors for severe COVID-19. The results of studies on the effect of antiretroviral drugs on the course of COVID-19 showed that HIV-infected patients receiving tenofovir + emtricitabine have a lower risk of severe COVID-19 and associated hospitalization than patients receiving other HIV treatment regimens. Clinical and preclinical data support the potential use of tenofovir in the treatment of novel coronavirus infection.
ABSTRACT
Objective: To explore the effect and mechanism of Xuanfei Jiere Granules in the treatment of corona virus disease 2019 (COVID-19) complicated with fever. Methods: The effective components of Xuanfei Jiere Granules were screened by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and the potential target genes were predicted. The disease targets of COVID-19 complicated with fever were searched by GeneCards and CTD databases, and the common targets were obtained, and then introduced into Cytoscape to construct the "component-target-disease" network. The above 2 common targets were input into the online database of STRING protein interaction, and the results were imported into Cytoscape software to obtain Protein-Protein Interaction(PPI) network;R language was used to analyze the common targets with Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis. Results: 84 active components and 82 targets were obtained. The pathway enrichment analysis showed that Xuanfei Jiere Granules mainly acted on protein kinase B(AKT1), tumor protein P53(TP53), interleukin-6(IL6) and other key targets in the treatment of COVID-19 complicated with fever. KEGG pathway enrichment analysis showed that the action was mainly related to the influence of fluid shear stress and atherosclerosis, human cytomegalovirus infection, and AGE-RAGE in diabetic complications and other signal pathways. The results of molecular docking showed that the core target had strong affinity with beta-sitosterol, formononetin, N-trans ferulyl tyramine and so on. Conclusion: This study preliminarily verified that Xuanfei Jiere Granules can play a role in the treatment of COVID-19 complicated with fever through multi-components, multi-targets and multi-pathways.
