Plain language summary
Sepsis related acute respiratory disease (ARDS) is associated with Covid-19. ARDS patients can present with decreased levels of vitamin C and so by association Covid-19 patients may also have low vitamin C levels. In this cohort study, 18 Covid-19 ARDS patients of which all survived were assessed for vitamin C levels. 17 patients had undetectable levels of vitamin C and one had low levels. It was concluded that more than 90% of the patients in this study had undetectable levels of vitamin C, which may be due to several reasons, such as reduced absorption of vitamin C in the gut and decreased production. Clinicians could use this study to understand the importance of monitoring vitamin C levels in patients with Covid-19.

Abstract
Acute respiratory distress syndrome (ARDS) is defined as the acute onset of noncardiogenic edema and subsequent gas-exchange impairment due to a severe inflammatory process. Recent report on the prognostic value of eicosanoids in patients with ARDS suggests that modulating the inflammatory response through the use of polyunsaturated fatty acids may be a useful strategy for ARDS treatment. The use of enteral diets enriched with eicosapentaenoic acid (EPA) and gamma-linolenic acid (GLA) has reported promising results, showing an improvement in respiratory variables and haemodynamics. However, the interpretation of the studies is limited by their heterogeneity and methodology and the effect of ω-3 fatty acid-enriched lipid emulsion or enteral diets on patients with ARDS remains unclear. Therefore, the routine use of ω-3 fatty acid-enriched nutrition cannot be recommended and further large, homogeneous, and high-quality clinical trials need to be conducted to clarify the effectiveness of ω-3 polyunsaturated fatty acids.
