简要总结
Baitouweng Decoction is traditionally used to treat large intestine damp-heat syndrome of ulcerative colitis (UC) by oral administration and rectal enema.The project applicant's invention of transendoscopic entral tubing (TET) has been used in Baitouweng Decoction for the treatment of UC across the whole colon, however, the efficacy have not been reported and the underlying mechanism is still unclear. Compared with oral and rectal enema, Baitouweng Decoction by colon TET can improve the therapeutic effect by increasing the concentration of drugs in the whole colon, which need to be verified. This project will reveal the prescription effect and drug-microbiome interaction mechanism of whole colon repeated administration of Baitouweng Decoction in the treatment of UC through clinical randomized controlled studies, deep intestinal dynamic sampling, integrated analysis of multi-omics and TCM prescription metabolomics studies, and provide key scientific basis for the establishment of a new approach of whole colon repeated administration of TCM and a new strategy for the treatment of UC.
详细描述
A multi-center randomized controlled study will be conducted to compare the efficacy differences and multi-omics changes of colon TET, rectal enema and oral Baitouweng Decoction in the control of intestine damp-heat syndrome of UC. Moreover，a group of patients was designed to receive blank carrier solution through colon TET tube. After the study, the patients in this group were given compensation treatment of fecal microbiota transplantation as an ethical protection measure.The colonic TET will be implanted into the intestine and the whole colon will be covered with Baitouweng Decoction. The treatment period is 10 days. The primary outcome measure is the changes of fecal calprotectin before and after oral, colonic TET and rectal enema administration. And the secondary outcomes measure are the changes of disease condition, Mayo score and safety. Deep intestine fluid, stool, blood and urine samples were collected before and after treatment to study the changes of microbiomes, metabolomics and immunoomics. Identify the difference of the key material basis of Baitouweng Decoction and analyze its mechanism comprehensively. The key beneficial and harmful bacteria were identified by comprehensive analysis. A total of not less than 144 subjects are expected to be included and divided into colonic TET treatment group, colonic TET placebo group, rectal enema group, and oral group according to a ratio of 1:1:1:1.
