COVID-19 Clinical Trial
Official title:
Beta-glucans as Immune Modulators Amongst Hospitalised Patients With COVID-19: A Pilot Randomised Trial
This randomised trial aims to assess the role of beta1-3 glucan supplementation in improving clinical symptoms and other outcomes amongst hospitalised patients with COVID-19.
COVID-19 can present as a life-threatening disease characterised by respiratory failure and high circulating levels of inflammatory cytokines. Beta-glucans comprise a heterogeneous group of natural polysaccharides consisting of D-glucose monomers linked by a beta-glycosidic bond. They represent key structural elements of the cell wall and may serve as energy storage in bacteria, fungi including yeast, algae, and plants. In this triple-masked randomised trial, hospitalised patients requiring treatment with supplemental oxygen because of a laboratory-confirmed infection by SARS-CoV-2 will receive supplementation with 1-3 beta-glucans or placebo as part of their standard treatment. The primary endpoint of this trial is the intensity of clinical symptoms as detected by the Wisconsin Upper Respiratory Symptom Survey (WURSS). Patients requiring mechanical ventilation at baseline will be excluded, as will those with cognitive impairment that precludes the use of clinical assessment scales, patients in which an order to limit therapeutic efforts has been issued, pregnant or breastfeeding women and those who decline to participate in this study. Secondary outcomes will include clinical deterioration requiring admission to an intensive care unit, requirement of high-flow nasal cannula or invasive mechanical ventilation and overall survival. Patients will be followed-up until hospital discharge or up to fifteen days after randomisation. Statistical analyses will be undertaken by a statistician unaware of treatment allocation under the intention-to-treat principle. ;
