The spread of SARS‐CoV‐2, along with the lack targeted medicaments, encouraged research existing drugs for repurposing. rapid response to SARS‐CoV‐2 infection comprises a complex interaction cytokine storm, endothelial dysfunction, inflammation, and pathologic coagulation. Thus, active molecules targeting multiple steps in lifecycle are highly wanted. Herein we explored silico capability silibinin from Silybum marianum interact main target proteins, vitro effects against cytokine‐induced‐inflammation dysfunction human umbilical vein cells (HUVECs). Computational analysis revealed that forms stable spike protein RBD, has good negative binding affinity Mpro, interacts many residues on site thus supporting its potentiality inhibiting viral entry replication. Moreover, HUVECs pretreatment reduced TNF‐α‐induced gene expression proinflammatory genes IL‐6 MCP‐1, as well PAI‐1, critical factor coagulopathy thrombosis, ET‐1, peptide involved hemostatic vasoconstriction. Then, due endothelium antiinflammatory anticoagulant properties proteins demonstrated herein, could be strong candidate COVID‐19 management multitarget perspective.

Abstract Coronavirus disease 2019 (COVID‐19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has led to an unprecedented setback for global economy and health. Vaccination is one of the most effective interventions substantially reduce death due SARS‐CoV‐2 infection. programmes are being rolled out globally, but these vaccines have been approved without extensive studies on their side‐effects efficacy. Recently, new‐onset autoimmune phenomena after COVID‐19 vaccination reported increasingly (e.g. immune thrombotic thrombocytopenia, liver diseases, Guillain–Barré syndrome, IgA nephropathy, rheumatoid arthritis systemic lupus erythematosus). Molecular mimicry, production particular autoantibodies role certain vaccine adjuvants seem be substantial contributors phenomena. However, whether association between manifestations coincidental or causal remains elucidated. Here, we summarize emerging evidence about occurring in response vaccines. Although information pertaining risk as a consequence controversial, merely propose our current understanding associated with vaccine. In fact, do not aim disavow overwhelming benefits mass preventing morbidity mortality. These reports could help guide clinical assessment management vaccination.

Over the past 16 years, three coronaviruses (CoVs), severe acute respiratory syndrome CoV (SARS-CoV) in 2002, Middle East (MERS-CoV) 2012 and 2015, SARS-CoV-2 2020, have been causing fatal human epidemics. The unpredictability of coronavirus disease-19 (COVID-19) poses a major burden on health care economic systems across world. This is caused by paucity in-depth knowledge risk factors for COVID-19, insufficient diagnostic tools detection SARS-CoV-2, as well absence specific effective drug treatments. While protective humoral cellular immune responses are usually mounted against these betacoronaviruses, to SARS-CoV2 sometimes derail towards inflammatory tissue damage, leading rapid admissions intensive units. lack mechanisms that tilt balance between two opposite outcomes threats many ongoing clinical trials dealing with immunostimulatory or immunoregulatory therapeutics. review will discuss innate cognate underlying deleterious reactions pathogenic coronaviruses.

Severe COVID-19 can manifest as multiorgan dysfunction with pulmonary involvement being the most common and prominent. As more reports emerge in literature, it appears that an exaggerated immune response form of unfettered complement activation a cytokine storm may be key driver widespread organ injury seen this disease. In addition, these patients are also known to hypercoagulable high rate thrombosis higher-than-expected failure anticoagulation. While macrovascular is individuals, frequent finding extensive microvascular thromboses several series case reports, raises possibility thrombotic microangiopathy (TMA) contributing factor multi-organ complications If correct, rapidly identifying TMA treating underlying pathophysiology allow for better outcomes critically ill patients. To further explore this, we reviewed published literature on COVID-19, looking describing TMA-like presentations. We summarize our findings here along discussion about presentation, pathophysiology, suggested treatment algorithm.
