Official title
Randomized Trial of Supplementing Glycine and N-acetylcysteine vs. Placebo in COVID-19
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
COVID-19 is associated with increased mortality, and has been linked to a 'cytokine inflammatory storm'. Populations at higher risk of COVID complications and mortality include the elderly, diabetic patients and immunocompromised patients (such as HIV), and the investigators have studied these 3 populations over the past 20 years and have found that they all have deficiency of the endogenous antioxidant protein glutathione (GSH), elevated oxidative stress, inflammation, impaired mitochondrial function, immune dysfunction, and endothelial dysfunction. It is known and established that GSH adequacy is necessary for neutralizing harmful oxidative stress, and that elevated oxidative stress appears to promote mitochondrial dysfunction. The combination of oxidative stress and mitochondrial dysfunction have also been linked to inflammation, immune dysfunction, and endothelial dysfunction. In prior studies in aging, the investigators have also identified that supplementing glutathione precursor amino-acids glycine and cysteine (provided as N-acetylcysteine) improves GSH deficiency and mitochondrial function, and lowers oxidative stress, inflammation, and endothelial dysfunction. The investigators have coined the term GlyNAC to refer to the combination of glycine and N-acetylcysteine. This study will evaluate the prevalence and extent of these defects in patients with COVID-19 admitted to the hospital, and the response to supplementing GlyNAC or placebo for 2-weeks. Because patients with COVID-19 are also being reported to have fatigue and cognitive impairment, the investigators will also measure fatigue and cognition at admission, 1-week and 2-weeks after beginning supplementation. The supplementation is stopped after completing 2-weeks, and these outcomes will be measured again after 4-weeks and 8-weeks after stopping supplementation.
