PG - 963-966 LID - S0085-2538(22)00726-8 [pii] LID - 10.1016/j.kint.2022.08.029 [doi] AB - In this issue, Farrah et al. report clinical investigations in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV). They demonstrate that endothelium-dependent vasodilatation, fibrinolytic capacity, and monocyte-dependent endothelin-1 clearance are reduced in patients with AAV, whereas circulating levels of endothelin-1 and vascular stiffness are increased. Acute infusion of an endothelin ET(A) receptor antagonist reduced vasoconstriction and arterial stiffness. This Commentary discusses biological insights and clinical implications of this study.
