Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Coronavirus was found to not only target the patient's lungs but also multiple organs. Around 2-33% of Coronavirus Disease-19 patients developed gastrointestinal symptoms. Studies have shown that Severe acute respiratory syndrome coronavirus 2 (SAR-CoV-2) was found in patient's feces, suggesting that the virus can spread through feces. In our previous study, stool samples from 15 patients with COVID-19 were analysed. Depleted symbionts and gut dysbiosis were noted even after patients were detected negative of SARS-CoV-2. A series of microbiota were correlated inversely with the disease severity and virus load. Gut microbiota could play a role in modulating host immune response and potentially influence disease severity and outcomes.
The investigators are uncertain about the impact of synbiotic on patients with COVID-19. However, a therapeutic strategy aiming at investigating the gut Imicrobiota of patients with COVID-9 who take synbiotic or not, leading to lesser progression to severe disease, less hospital stay and improved quality of life.

Coronavirus was found to not only target the patient's lungs, but also multiple organs. Around 2-33% of COVID-19 patients developed gastrointestinal symptoms.

Gut microbiota could play a role in modulating host immune response and potentially influence disease severity and outcomes.
In July 2020, there are more than 15 million confirmed cases globally with 620 thousand deaths. Currently, there are more than 2000 confirmed cases of COVID-19 in Hong Kong. The investigators are uncertain about the impact of synbiotic on patients with COVID-19. However, a therapeutic strategy aiming at investigating the gut Imicrobiota of patients with COVID-9 who take synbiotic or not, leading to lesser progression to severe disease, less hospital stay and improved quality of life.
