ACE2 and pulmonary fibrosis: Even though the literature did establish the association between CAPA and PVDs, we hypothesize that CAPA may trigger PVDs, as the pathophysiological mechanisms have shown extended pulmonary fibrosis and thromboembolism as well as fungal angio-trophism, thereby facilitating SARS-CoV-2 entry into the target cell via ACE2.
