Cracking info there, some of the language is difficult to digest. I have cut the first paragraph which I believe is important for treatment for covid 19. Not just the initial viral load, but the reduced vascular leakage, (Ards) and also the adenosine upreguate of cd73 anti imflammatory response, would this reduce the cytokine storm.
Type I interferons (interferon alpha and beta among others) are our first line of defence in infections (Levy et. al., 2003). As a counter measure to acute insults type I interferons enhance cell membrane and vascular integrity. Vascular leakage is an important feature in sepsis; severe respiratory viral infections, such as MERS, SARS and influenza; viral hemorrhagic fever, such as Ebola; systemic inflammatory response syndrome (SIRS) and ischemia-reperfusion injuries brought forth by major trauma or cardiovascular surgery. Type I interferons have the ability to up-regulate CD73, a molecule which yields anti-inflammatory adenosine (Jalkanen and Salmi, 2006). CD73 derived adenosine enhances endothelial barrier function and leads to the prevention of vascular leakage, the predominant pathophysiological event in acute organ injury (Kiss et. al., 2007), namely acute respiratory distress syndrome (ARDS), acute kidney injury (AKI) and multi-organ failure (MOF). Vascular leakage in acute lung injury (ARDS) allows plasma exudation into the alveolar space leading to potentially life-threatening hypoxaemia. Interferon beta-1a has been shown to reduce the impact of ARDS by reducing vascular leakage (Bellingan et. al., 2014).
My conclusion is that given at the right time this treatment could be a game changer. Which treats the majority of the c19 symptoms from early onset to when the infection leads to the point of going onto a ventilator. (Ards, cytokine storm late stage covid 19) all IMO of which I will be happily corrected. DYOR.
