Abstract
Objectives
Severe COVID-19 (SvC19) is a syndrome of acute lung injury, respiratory failure, cytokine storm, distributive shock, multi-system organ failure and high mortality. SvC19 disproportionately impacts the elderly, who are also at risk for micronutrient deficiency. After observing a beneficial response to micronutrient repletion (MR) in a 69 year-old male with SvC19, we hypothesized that nutritional deficiencies were linked to the pathogenesis and that correcting them could be beneficial. In this report we detail a case series of 18 older patients with SvC19 treated with MR.
Methods
All patients had SvC19 requiring mechanical ventilation, elevated levels of CRP, D-dimer and neutrophil to lymphocyte ratio. MR consisted of daily parenteral ascorbate, thiamine, pyridoxine and multivitamins, as well as daily ergocalciferol, zinc and carnitine via nasogastric tube.
Results
The average age was 63.3 years. Six patients were male, 12 female. Disease severity was comparable based on SOFA score. A partial response was observed in 10 of the 18 patients (55.5%). Six (33.3%) were able to wean off blood pressure support. Five (27.7%) had improvement in gas exchange. Four (22.2) were able to wean off ventilator support. Three patients (37.5%) showed improvement in renal dysfunction.
Conclusions
MR shows potential promise as an adjunctive treatment for severe COVID-19, particularly in older patients or those with chronic illness in whom nutritional deficiencies are more probable.
