Clinical Study of Selective Fecal Microbiota Transplantation in the Treatment of Irritable Bowel Syndrome.

May 17, 2021 updated by: Yanling Wei

Clinical Comparative Study of Precision Flora Transplantation and Standardized Fecal Microbiota Transplantation in Patients With Irritable Bowel Syndrome.

In order to seek a more precise and convenient treatment, we made a self-made precise transplant capsule that is effective against diarrhea. Compared with standardized fecal microbiota transplantation transplantation on the treat of diarrhea-type irritable bowel syndrome. To observe the similarities and differences of the effect between the two treatment methods on the disease. and the changes in intestinal bacteria was also observed.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In order to clarify the effectiveness of precision fecal bacteria transplantation, we have independently developed precision transplantation capsules. Seventy patients with diarrhea-type irritable bowel syndrome were selected and randomly divided into 2 groups. The patients in the first group were treated with standard fecal bacteria transplantation once, and the patients in other group were treated with precision transplantation capsules for 28 days. The clinical symptoms of the patients of the two groups were observed before and 2, 4, 8, 12, 24, and 48 weeks after the treatment, and stool samples were collected for intestinal flora detection. The purpose is to observe and compare the efficacy of the two treatment methods and their influence on the intestinal flora.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Active Comparator: FMT group
Standardized FMT once.Extract all the flora from the feces provided by the donor to make fecal bacteria transplant capsules. The patient took orally on an empty stomach, each time using 3.2g of fecal bacteria.
Procedure: Standardized FMT
The group includes 35 patients. They will receive standardized FMT. Fecal bacteria capsules are used for fecal bacteria transplantation, 16 capsules are used each time, each capsule contains 200mg of fecal bacteria, and it is used orally. It was given only once.
Experimental: JZ group
1.6g Po perday,for 28 days. probiotics that are effective against diarrhea were selected to make precise flora capsules, which are taken when the patient is on an empty stomach, once a day, using 1.6 g of bacteria per day, orally for 28 consecutive days.
Combination product: Precision Flora Transplantation
The group includes 35 patients. They will receive Precision Flora Transplantation. They were used self-developed precision transplant capsules for precision flora transplantation. 4 capsules are used each time. Each capsule contains 400mg of various probiotics effective against diarrhea. It is used orally, once a day,for 28 days.
