Abstract

The discovery that SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) binds to the angiotensin converting enzyme (ACE)-2, which is highly expressed in the lower airways, explained why SARS-CoV-2 causes acute respiratory distress syndrome (ARDS) and respiratory failure. After this, news spread that ACEis and ARBs would be harmful in SARS-CoV-2-infected subjects. To the contrary, compelling evidence exists that the ACE-1/angiotensin(Ang)II/ATR-1 pathway is involved in SARS-CoV-2-induced ARDS, while the ACE-2/Ang(1-7)/ATR2/MasR pathway counteracts the harmful actions of AngII in the lung. A reduced ACE-1/ACE-2 ratio is, in fact, a feature of ARDS that can be rescued by human recombinant ACE-2 and Ang(1-7) administration, thus preventing SARS-CoV-2-induced damage to the lung. Based on the current clinical evidence treatment with ACE-inhibitors I (ACEis) or angiotensin receptor blockers (ARBs) continues to provide cardiovascular and renal protection in patients diagnosed with COVID-19. Discontinuing these medications may therefore be potentially harmful in this patient population.

    Acid-base conditions modify artery tone and tissue perfusion but the involved vascular sensing mechanisms and disease consequences remain unclear. We experimentally investigated transgenic mice and performed genetic studies in a UK-based human cohort. We show that endothelial cells express the putative HCO3-sensor receptor-type tyrosine-protein phosphatase RPTPg, which enhances endothelial intracellular Ca2+-responses in resistance arteries and facilitates endothelium-dependent vasorelaxation only when CO2/HCO3 is present. Consistent with waning RPTPg-dependent vasorelaxation at low [HCO3], RPTPg limits increases in cerebral perfusion during neuronal activity and augments decreases in cerebral perfusion during hyperventilation. RPTPg does not influence resting blood pressure but amplifies hyperventilation-induced blood pressure elevations. Loss-of-function variants in PTPRG, encoding RPTPg, are associated with increased risk of cerebral infarction, heart attack, and reduced cardiac ejection fraction. We conclude that PTPRG is an ischemia susceptibility locus; and RPTPg-dependent sensing of HCO3 adjusts endothelium-mediated vasorelaxation, microvascular perfusion, and blood pressure during acid-base disturbances and altered tissue metabolism.

    Review Article

    Obesity and diabetes are established comorbidities for COVID-19. Adipose tissue demonstrates high expression of ACE2 which SARS- CoV-2 exploits to enter host cells. This makes adipose tissue a reservoir for SARS-CoV-2 viruses and thus increases the integral viral load. Acute viral infection results in ACE2 downregulation. This relative deficiency can lead to disturbances in other systems controlled by ACE2, including the renin-angiotensin system. This will be further increased in the case of pre-conditions with already compromised functioning of these systems, such as in patients with obesity and diabetes. Here, we propose that interactions of virally-induced ACE2 deficiency with obesity and/or diabetes leads to a synergistic further impairment of endothelial and gut barrier function. The appearance of bacteria and/or their products in the lungs of obese and diabetic patients promotes interactions between viral and bacterial pathogens, resulting in a more severe lung injury in COVID-19.
