KNG1 and COVID-19: At the present time, it has been reported that plasma levels of Ang II in SARS-CoV-2 infected patients are markedly elevated as compared with healthy subjects (interquartile range between 260–360 pg/mL and 65–120 pg/mL, respectively) and linearly associated to viral load and lung injury [177]; unfortunately, nobody has tested the levels of Ang (1–7), Ang (1–9), Ang (1–5) and bradykinin (1–7), some of which might be at high levels as well, thus justifying both normo/hypotension and eosinopaenia in COVID-19 patients.
