Kallikrein Activity

COVID-19 patients can present with pulmonary edema early in disease. We propose that this is due to a local vascular problem because of activation of bradykinin 1 receptor (B1R) and B2R on endothelial cells in the lungs. SARS-CoV-2 enters the cell via ACE2 that next to its role in RAAS is needed to inactivate des-Arg9 bradykinin, the potent ligand of the B1R. Without ACE2 acting as a guardian to inactivate the ligands of B1R, the lung environment is prone for local vascular leakage leading to angioedema. Here, we hypothesize that a kinin-dependent local lung angioedema via B1R and eventually B2R is an important feature of COVID-19. We propose that blocking the B2R and inhibiting plasma kallikrein activity might have an ameliorating effect on early disease caused by COVID-19 and might prevent acute respiratory distress syndrome (ARDS). In addition, this pathway might indirectly be responsive to anti-inflammatory agents.

There are two categories of pulmonary edema: edema caused by increased capillary pressure (hydrostatic or cardiogenic edema) and edema caused by increased capillary permeability (noncardiogenic pulmonary edema, or acute respiratory distress syndrome [ARDS]). This review focuses on noncardiogenic pulmonary edema and describes the general approach to patients with suspected pulmonary edema. The pathogenesis, diagnosis, treatment, and outcome of noncardiogenic pulmonary edema are reviewed. Miscellaneous causes of pulmonary edema are discussed, including neurologic insults, exposure to high altitude, reexpansion of a collapsed lung, lung transplantation, upper airway obstruction, drugs, and lung resection. Figures include chest scans showing pulmonary edema and noncardiogenic pulmonary edema, an illustration of the differences between cardiogenic and noncardiogenic edema, and a chart comparing lung mechanics and other variables in experimental models of cardiogenic pulmonary edema and noncardiogenic edema. Tables show clinical characteristics of patients with noncardiogenic pulmonary edema, the definition of ARDS, causes of ARDS, and treatments for ARDS that do not involve ventilation. This review contains 3 figures, 9 tables, and 55 references. Key words: acute respiratory distress syndrome, diffuse alveolar damage, noncardiogenic pulmonary edema, pulmonary edema

Alveolar Capillary

Capillary endothelial cells possess a specialized metabolism necessary to adapt to the unique alveolar-capillary environment. Here, we highlight how endothelial metabolism preserves the integrity of the pulmonary circulation by controlling vascular permeability, defending against oxidative stress, facilitating rapid migration and angiogenesis in response to injury, and regulating the epigenetic landscape of endothelial cells. Recent reports on single cell RNA sequencing reveal subpopulations of pulmonary capillary endothelial cells with distinctive reparative capacities which potentially offers new insight into their metabolic signature. Lastly, we discuss broad implications of pulmonary vascular metabolism on acute respiratory distress syndrome, touching on emerging findings of endotheliitis in Coronavirus Disease 2019 (COVID-19) lungs.

Onyx Copolymer

Purpose. We report a case of a 60-year-old male who underwent sequential Onyx embolizations of a cerebral arteriovenous malformation (AVM) which we implicate as the most likely etiology of subsequent acute respiratory distress syndrome (ARDS).Methods. Case report and literature review.Results. Shortly after the second Onyx embolization procedure, the patient declined from respiratory failure secondary to pulmonary edema. Clinical entities typically responsible for pulmonary edema including cardiac failure, renal failure, iatrogenic volume overload, negative-pressure pulmonary edema, and infectious etiologies were evaluated and excluded. The patient required mechanical ventilatory support for several days, delaying operative resection. The patient met clinical and radiographic criteria for ARDS. After excluding other etiologies of ARDS, we postulate that ARDS developed as a result of Onyx administration. The Onyx copolymer is dissolved in dimethyl sulfoxide (DMSO), a solvent excreted through the lungs and has been implicated in transient pulmonary side effects. Additionally, a direct toxic effect of the Onyx copolymer is postulated.Conclusion. Onyx embolization and DMSO toxicity are implicated as the etiology of ARDS given the lack of other inciting factors and the close temporal relationship. A strong physiologic rationale provides further support. Clinicians should consider this uncommon but important complication.
