Abstract Background The reactivation of herpesviruses (HHV) in COVID-19 patients is evident the literature. Several reports have been published regarding these viruses (HSV, VZV, EBV, and CMV) among those who got vaccines. In this study, we aimed to review current evidence assess whether HHVs has any association with prior administration Methods A systematic search was conducted on 25 September 2022 PubMed/MEDLINE, Web Science, EMBASE. We included all observational studies, case reports, series which reported human following Results Our showed 80 articles that meet eligibility criteria. Among evaluated vaccines, most vaccines were mRNA based.

Consistent with well-established biochemical properties of coronaviruses, sialylated glycan attachments between SARS-CoV-2 spike protein (SP) and host cells are key to the virus’s pathology. SP attaches aggregates red blood (RBCs), as shown in many pre-clinical clinical studies, causing pulmonary extrapulmonary microthrombi hypoxia severe COVID-19 patients. heavily surfaces platelets (which, like RBCs, have no ACE2) endothelial (having minimal compound this vascular damage. Notably, experimentally induced RBC aggregation vivo causes same morbidities for COVID-19, including microvascular occlusion, clots, myocarditis. Key risk factors morbidity, older age, diabetes obesity, all characterized by markedly increased propensity clumping. For mammalian species, degree susceptibility correlates aggregability p = 0.033. five human betacoronaviruses, two common cold strains express an enzyme that releases attachments, while deadly SARS, MERS do not, although viral loads infections similar. These insights also explain previously puzzling efficacy certain generics against may support development future therapeutic strategies long COVID

The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome 2 (SARS-CoV-2), has become a global health concern. Three years since its origin, despite the approval of vaccines and specific treatments against this new coronavirus, there are still high rates infection, hospitalization, mortality in some countries. COVID-19 is characterised inflammatory state coagulation disturbances that may be linked to purinergic signalling molecules such as adenosine triphosphate (ATP), diphosphate (ADP), (ADO), receptors (P1 P2). These nucleotides/nucleosides play important roles cellular processes, immunomodulation, blood clot formation, vasodilation, which affected during SARS-CoV-2 infection. Therefore, drugs targeting pathway, currently used for other pathologies, being evaluated preclinical clinical trials COVID-19. In review, we focus on potential these control release, degradation, reuptake extracellular nucleotides nucleosides treat Drugs P1 could have therapeutic efficacy due their capacity modulate cytokine storm immune response.

However, according available data, most promising medications treatment those platelets behaviour factors, mainly through P2Y12 receptor.
