Abstract
OBJECTIVE: Coronavirus disease 2019 (COVID-19) is often accompanied by gastrointestinal symptoms, which are related to gut microbiota dysbiosis (GMD). Whether washed microbiota transplantation (WMT) is an effective treatment for COVID-19 patients suspected of having GMD by restoring the gut microbiota is unknown. This study is designed to explore the efficacy and safety of WMT in COVID-19 patients suspected of having GMD. METHODS: This is a randomized, multicenter, single-blind prospective study. COVID-19 patients suspected of having GMD will be randomly divided to receive routine treatment only or to receive routine treatment and WMT. The frequency of WMT will be once a day for three consecutive days. Laboratory and imaging examinations will be performed at admission, 1 and 2 weeks after treatment, and on the day of discharge. Then a telephone follow-up will be conducted at 1st week, 2nd week, and 6th month after discharge. The clinical efficacy and safety of WMT in COVD-19 patients suspected of having GMD and the effects of WMT on the organ function, homeostasis, inflammatory response, intestinal mucosal barrier function, and immunity of the patients will be evaluated. RESULTS: By following the proposed protocol, WMT is expected to be efficacious and safe for the treatment of COVID-19 patients suspected of having GMD, and the therapeutic effect is expected to be associated with improvement of the intestinal mucosal barrier function, inflammatory response, and immunity. CONCLUSION: The findings from this study may offer a new approach for the prevention and treatment of COVID-19 patients suspected of having GMD.
