Overview
Brief Summary
In December 2019, a cluster of pneumonia cases of unidentified cause emerged in Wuhan,was identified as the culprit of this disease currently being identified as "Coronavirus Disease 2019" (COVID-19) by World Health Organization.
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.
Detailed Description
In December 2019, a cluster of pneumonia cases of unidentified cause emerged in Wuhan, Hubei province, China. In early January, a novel betacoronavirus forming another clade within the subgenus sarbecovirus, now named SARS-CoV-2, was identified as the culprit of this disease currently being identified as "Coronavirus Disease 2019" (COVID-19) by WHO. 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. Studies have shown that 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. 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.

Outcomes
Primary Outcomes
Combined symptom score
Time Frame: 4 weeks
Combined symptom score improvement of the first 4 weeks. Symptoms score assessment ranges from 20-80. The higher the score, the worse the symptoms.
Secondary Outcomes

- Duration of hospital stay(up to 3 months)
- Time to negative PCR(through study completion, an average of 1 year)
- Trend of symptom score(4 weeks)
- Gastrointestinal symptoms(4 weeks)
- Changes in fecal bacteria metabolites(weeks 2, 4, 5 and 8 months 3, 6, 9 and 12)
- Change in plasma cytokines level(week 2 and week 5)
- Changes in the gut microbiome(weeks 1, 2, 3, 4, 5, 8 and months 3, 6, 9 and 12)
- Number of admission to Intensive Care Unit(4 weeks)
- Number of subjects with home discharge(4 weeks)
- Number of mortality(4 weeks)
- Number of days absent from work(3 months)
- Change of quality of life questionnaire(week 8, months 3, 6, 9 and 12)
