COVID-19 Clinical Trial
Official title:
Efficacy of Tannin Specific Natural Extract for Coronavirus Disease (COVID-19): Randomized Controlled Trial
There is an urgent need to evaluate interventions that could be effective against the infection with SARS-CoV 2. Tannins based wood extracts are an inexpensive and safe product with protective effect in both bacterial and viral infections likely due to its anti- inflammatory, anti-oxidative effects and their modulation of the intestinal microbiota. This randomized controlled trial seeks to evaluate the efficacy of the tannins based dietary supplement ARBOX in positive COVID-19 patients.
The epidemic of 2019 novel coronavirus (causing the disease Covid-19) has expanded from Wuhan throughout China and is being exported to a growing number of countries, some of which have seen onward transmission. COVID-19 caused clusters of severe respiratory illness and was associated with 2% mortality. There is currently no vaccine and no specific antiviral treatment recommended for COVID-19. About 20% of the patients were severe and the mainstay of clinical management is largely symptomatic treatment, with organ support in intensive care for seriously ill patients. Therefore, it is urgent to find a safe and effective therapeutic approach to COVID-19. Tannins have been shown to have antioxidant, anti-inflammatory, antimicrobial properties and a regulatory effect on the gastrointestinal metabolism. The investigators will realize a prospective, double-blind, randomized trial to assess the effect of treatment with a dietary supplement (ARBOX), a molecular complex of quebracho and chestnut tannins extract and Vit B12, compared with placebo. 140 COVID-19 patients will be recruited in a single center in Buenos Aires Argentina. 70 patients will receive conventional treatment plus ARBOX (treated group) and 70 patients will receive conventional treatment plus placebo (control group). The effects will be evaluated during the 28 days follow up. The primary end point will be the time of discharge from the hospital. A panel of 27 cytokines level, intestinal microbiota composition and its metabolites will be assessed at day 1 and 14. ;
