Severe respiratory infections are characterized by elevated inflammation and generation of reactive oxygen species (ROS) which may lead to a decrease in antioxidants such as vitamin C and a higher requirement for the vitamin.

Authors: Supady A, Taccone FS, Lepper PM, Ziegeler S, Staudacher DL PMID: 33648538 PMCID: PMC7919616 DOI: 10.1186/s13054-021-03486-9 Abstract Survival of coronavirus disease 2019 (COVID-19) patients with severe respiratory failure treated with veno-venous extracorporeal membrane oxygenation (V-V ECMO) ranges around 60%, according to recent studies. Initial recommendations for the use of V-V [...]

Authors: Caplan M, Goutay J, Bignon A, Jaillette E, Favory R PMID: 33093279 DOI: 10.1097/CCM.0000000000004711 Abstract Objectives: Treating acute respiratory failure in patients with coronavirus disease 2019 is challenging due to the lack of knowledge of the underlying pathophysiology. Hypoxemia may be explained in part by the loss of hypoxic pulmonary vasoconstriction. The present study [...]

Authors: Bagate F, Tuffet S, Masi P, Perier F, Razazi K PMID: 33150525 PMCID: PMC7641257 DOI: 10.1186/s13613-020-00769-2 Abstract Background: In COVID-19 patients with severe acute respiratory distress syndrome (ARDS), the relatively preserved respiratory system compliance despite severe hypoxemia, with specific pulmonary vascular dysfunction, suggests a possible hemodynamic mechanism for VA/Q mismatch, as hypoxic vasoconstriction alteration.

Authors: Tomazini BM, Maia IS, Cavalcanti AB, Berwanger O, Rosa RG, Veiga VC PMID: 32876695 PMCID: PMC7489411 DOI: 10.1001/jama.2020.17021 Abstract Importance: Acute respiratory distress syndrome (ARDS) due to coronavirus disease 2019 (COVID-19) is associated with substantial mortality and use of health care resources. Dexamethasone use might attenuate lung injury in these patients. Objective: To determine [...]
