简要总结
To evaluate the overall efficacy of repeated Transcranial Magnetic Stimulation(rTMS) combined with a Live Probiotic tablet (Combined Bifidobacterium, Lactobacillus, Enterococcus and Bacillus cereus Tablets, Live) in Diarrhea-Predominant Irritable Bowel Syndrome (IBS-D)
Methods:
Clinical efficacy evaluation of TMS combined with Live Probiotic tablet for chronic diarrhea in IBS patients. The 400 IBS patients who meet the recruitment criteria for the clinical study will be randomized into 100 patients in rTMS combined with Live Probiotic tablet (Combined Bifidobacterium, Lactobacillus, Enterococcus and Bacillus cereus Tablets, Live), rTMS combined placebo, shamrTMS combined with Live Probiotic tablet(Combined Bifidobacterium, Lactobacillus, Enterococcus and Bacillus cereus Tablets, Live) and shamrTMS combined placebo group. Corresponding treatment was given for 2 week, rTMS group received 1 Hz/s, 20 min for 2 week; Live Probiotic tablet group received tablets orally, 150 mg three times a day for 2 week, shamrTMS group received 0 Hz/s, 20 min for 2 week; placebo group received tablets orally, 150 mg three times a day for 2 week. Clinical assessment included symptoms, stool traits, mood, and sleep.
- Study on the mechanism of using intestinal flora data to evaluate the treatment of chronic diarrhea in IBS patients. 30 cases each were included in the 4 groups of IBS-eligible patients, and repeated transcranial magnetic stimulation treatment was given to the patient group for 2 week, and the patient group underwent the assessment of investigating the quantity and metabolic changes of the intestinal flora in feces before and after the treatment.
详细描述
A large number of literature has reported that repetitive transcranial magnetic stimulation(rTMS) can relieve chronic pain. The specific mechanisms include that rTMS can change the excitability of the cerebral cortex, improve cerebral blood flow and metabolism, regulate neurotransmitter and gene expression, and plastic changes in the nervous system.Previous research results revealed that the neural circuit of the cuticular nucleus - anterior cingulate cortex is a unique neural circuit regulating chronic visceral pain in the IBS animal model. To explore the improvement of chronic visceral pain sensitivity in patients with irritable bowel syndrome (IBS) by Transcranial magnetic stimulation (TMS). On this basis, To further explore whether repetitive transcranial magnetic stimulation can treat the diarrhea symptoms of patients with irritable bowel syndrome, and to provide a more reliable and effective treatment method for clinical application.
Objective:
To evaluate the overall efficacy of repeated Transcranial Magnetic Stimulation(rTMS) Combined with a Live Probiotic tablet (Combined Bifidobacterium, Lactobacillus, Enterococcus and Bacillus cereus Tablets, Live) in Diarrhea-Predominant Irritable Bowel Syndrome (IBS-D), including abdominal diarrhea symptoms,bowel symptoms, and psychiatric symptoms (anxiety, depression, sleep disturbance). And also to explore the mechanism of rTMS combined with Live Probiotic tablet for the treatment of IBS-D, based on intestinal flora data.
Methods:
Clinical efficacy evaluation of TMS combined with Live Probiotic tablet for chronic diarrhea in IBS patients. The 400 IBS patients who meet the recruitment criteria for the clinical study will be randomized into 100 patients in rTMS combined with Live Probiotic tablet (Combined Bifidobacterium, Lactobacillus, Enterococcus and Bacillus cereus Tablets, Live), rTMS combined placebo, shamrTMS combined with Live Probiotic tablet(Combined Bifidobacterium, Lactobacillus, Enterococcus and Bacillus cereus Tablets, Live) and shamrTMS combined placebo group. Corresponding treatment was given for 2 week, rTMS group received 1 Hz/s, 20 min for 2 week; Live Probiotic tablet group received tablets orally, 150 mg three times a day for 2 week, shamrTMS group received 0 Hz/s, 20 min for 2 week; placebo group received tablets orally, 150 mg three times a day for 2 week. Clinical assessment included symptoms, stool traits, mood, and sleep.

结局指标
主要结局
Frequency of defecation and Bristol Stool Form Scale score
时间窗: One day before treatment, the first day after the end of treatment, and follow-up until the third month after treatment
The therapeutic effect was evaluated by recording the frequency of defecation and the state of feces of the patients before and after treatment. The Bristol Stool Form Scale is to standardize the classification of stool consistency and form. * Types 1-2: Hard, lumpy stools (associated with constipation). * Types 3-4: Loose or smooth stools (ideal consistency). * Types 5-7: Watery, mushy, or liquid stools (linked to diarrhea). The Bristol Stool Form Scale (BSFS) is for monitoring treatment responses to interventions.
次要结局
- IBS-symptom severity score(One day before treatment, the first day after the end of treatment, and follow-up until the third month after treatment)
