Our results are also discordant with the study by Silva et al. (2022) in Argentina, in fact, in their study, patients with COVID-19 showed higher levels of ACE2 compared to healthy patients Ang-(1–7) and Ang II were significantly lower [29] and the study by Ghimire et al. (2023) in which Ang 1–7 levels were significantly lower, whereas Ang II levels were higher in the COVID-19 patients than in healthy control individuals [30]. Here, ACE2 is linked to COVID-19.
