Fibrotic lung changes are well-known complications of SARS, MERS, and ARDS from other causes and are anticipated in recovered COVID patients. However, there is limited data so far showing a temporal relationship between lung changes on imaging in the acute phase and follow-up imaging after recovery from the infection. We present 12 patients who demonstrate the development of interstitial lung changes and pulmonary fibrosis in the same distribution and pattern as the acute phase findings, up to 6 months after the acute infection, demonstrating a direct relationship between these changes and COVID-19 pneumonia...

Acute respiratory distress syndrome (ARDS) is a common clinical critical condition of the respiratory system, with a high fatality rate and lack of effective drug treatment, hence it is a global medical problem to be solved urgently. Recently, with the in-depth research on extracellular vesicles (EVs) at home and abroad, more and more evidences suggest that EVs play a critical role in the initiation, development and progression of ARDS and have potential clinical application value. The role of different cells derived EVs in ARDS will be reviewed in this paper...

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a common respiratory disease in clinic, and with a pathological manifestation of pulmonary edema, decreased pulmonary compliance as well as pulmonary epithelial/endothelial cells injury. At present, it was suggested that systemic inflammatory response syndrome (SIRS) caused by various causes which play an important role in the occurrence and development of ALI/ARDS. Widely activated neutrophils can migrate to lung tissue and release plenty of proteases in the procedure of SIRS, including neutrophil serine proteases (NSPs), lysozyme, myeloperoxidase and collagenase, which can induce severe lung injury...

Due to frequent and often severe lung affections caused by COVID-19, murine models of acute respiratory distress syndrome (ARDS) are increasingly used in experimental lung research. The one induced by a single lipopolysaccharide (LPS) exposure is practical. However, whether it is preferable to administer LPS intranasally or intratracheally remains an open question. Herein, female C57Bl/6 J mice were exposed intranasally or intratracheally to one dose of either saline or 3 mg/kg of LPS. They were studied 24 h later...

Little is known about the light phenotype of SARS-CoV-2 pneumonia, which behaves in an unusual way, unlike other known respiratory diseases. We believe that the histopathological features of early COVID-19 could be considered the pathophysiological hallmark of this disease. Lung cryobiopsies show almost pristine alveoli, enlarged/hyperplasic alveolar capillaries along with dilatation of the post capillary pulmonary venules. Hypoxemia could therefore be explained by a reduction of the normal V/Q ratio, due to blood overflow around well ventilated alveoli...

PURPOSE: While full description of pediatric COVID-19 manifestations is evolving, children appear to present less frequently, and often display a less severe disease phenotype. There is correspondingly less data regarding pediatric radiologic findings. To describe the imaging findings of pediatric COVID-19, we evaluated the radiologic imaging of the initial patient cohort identified at our institution. METHODS: In this IRB approved study, all patients at our institution aged 0-21 with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) based on PCR or immunoglobulin testing were identified...

Since November 2019, SARS Coronavirus 2 disease (COVID-19) pandemic has spread through more than 195 nations worldwide. Though the coronavirus infection affects all age and sex groups, the mortality is skewed towards the elderly population and the cause of death is mostly acute respiratory distress syndrome (ARDS). There are data suggesting the role of excessive immune activation and cytokine storm as the cause of lung injury in COVID-19. The excessive immune activation and cytokine storm usually occurs due to an imbalance in redox homeostasis of the individuals...

BACKGROUND: Intravenous fluids are widely used to treat circulatory deterioration in pediatric acute respiratory distress syndrome (PARDS). However, the accumulation of fluids in the first days of PARDS is associated with adverse outcome. As such, early fluid restriction may prove beneficial, yet the effects of such a fluid strategy on the cardio-pulmonary physiology in PARDS is unclear. In this study, we compared the effect of a restrictive to a liberal fluid strategy on hemodynamic response and the formation of pulmonary edema in an animal model of PARDS...
