Washed Microbiota Transplantation for Malnutrition After Nonphysiological Reconstruction of the Upper Gastrointestinal Tract

Официальное название

An Open-label, Multicenter, Randomized Clinical Trial for Malnutrition After Nonphysiological Reconstruction of the Upper Gastrointestinal Tract: Washed Microbiota Transplantation Via Mid-gut Tube Versus Colonic Transendoscopic Enteral Tube

Обзор

This is a prospective, randomized, multicenter study to evaluate WMT in improving nutritional status in malnourished patients who underwent nonphysiological reconstruction of the upper gastrointestinal tract. In this multicenter trial, sixty-two patients will be enrolled in forteen Chinese sites. Participants will be randomized at a ratio of 1:1 to receive three WMTs through either mid-gut tube or colonic TET. After WMT, each participant will receive free diet plus home enteral nutrition. Home enteral nutrition should last for 2 months at home, with blood, urine and stool samples taken and stored at baseline and 2 months after WMT.

Подробное описание

Background: Malnutrition is a common complication of nonphysiological reconstruction of the upper gastrointestinal tract. The potential of washed microbiota transplantation (WMT) in improving nutritional status have been reported. The surgery procedure alters the anatomy and physiology of the digestive tract, which might impact the efficacy and safety of WMT when choosing different delivery way. This study aims to explore the optimal delivery of WMT in malnourished patients after rerouting of the upper gastrointestinal tract.

Methods and design: This multicenter, open-label, and randomized controlled trial will be conducted at forteen hospitals in China. Enteral nutrition (EN) will be administrated at enrollment. Participants will be then randomized at a ratio of 1:1 to receive three WMTs through either mid-gut tube or colonic transendoscopic enteral tubing (TET). Then the patients will receive free diet coupled with home enteral nutrition (HEN) for 8 weeks in both groups, with blood, urine and stool samples taken and stored at baseline and 2 months after WMT. The observation duration is 8 weeks. The primary endpoint is nutritional status of the patients. The nutritional status data obtained at baseline and 8 weeks after discharge includes body mass index (BMI) and skeletal muscle index (SMI). The secondary endpoints are nutritional assessment, nutrition-based laboratory indices, 60-day readmission rate, quality of life, gastrointestinal symptom scale, the safety of WMT and further analysis of the biological specimens.

Conclusion: It is estimated that WMT would help improve nutrition status. Moreover, this trial has the potential to identify the optimal delivery of WMT for patients undergoing nonphysiological reconstruction of the upper gastrointestinal tract.

Вмешательства

  Each patient will receive washed microbiota transplantation each day for three consecutive days. After WMT, participants will receive free diet plus home enteral nutrition (solution at a 750ml daily dosage that provides 750 kcal energy) at home for 8 weeks.
