Pilot clinical trial

研究目的:

评估TaVNS对二甲双胍所致腹泻的糖尿病患者的临床疗效。以探讨TaVNS在不减少或停用二甲双胍的情况下,缓解腹泻等胃肠不适症状,并且能够协同降低血糖,提供证据。

Objectives of Study:

To evaluate the clinical efficacy of TaVNS in diabetic patients with metformin-induced diarrhea. To explore the evidence that TaVNS relieves gastrointestinal discomfort such as diarrhea and can synergistically lower blood glucose without reducing or discontinuing metformin.

Description for medicine or protocol of treatment in detail:

纳入标准:

糖尿病诊断标准:符合其中之一:空腹(至少8-14小时无热量摄入)静脉或毛细血管血浆葡萄糖(FPG)>126mg/dl(7.0mmol/L);餐后2小时静脉血浆葡萄糖>200mg/dl(11.1mmol/L);餐后2小时毛细血管血浆葡萄糖>220mg/dl(12.2mmol);随机血糖>200mg/d1(11.1mmol/L);糖化血红蛋白(HbAIc)>6.5%。二甲双胍所致腹泻诊断标准 根据既往高质量文献研究,近期曾应用或正在应用二甲双胍500mg bid以上出现腹泻现象,使用前未腹泻,排除其他原因引起的腹泻,如慢性腹泻、食物中毒、糖尿病自主神经功能紊乱、溃疡性结肠炎、克罗恩病等,应考虑到二甲双胍相关性腹泻的可能。泄泻分级根据《中药新药临床研究指导原则(试行)》拟定。(1)轻度泄泻:大便不成形,每天3-4次;(2)中度泄泻:大便稀溏,每天5-10次;(3)重度泄泻:大便如水样,每天10次以上。 ①符合以上诊断标准者,其中泄轻、中度泄泻纳入; ②年龄在18~80岁之间,男女不限; ③对研究人员观察和治疗有良好的依从性; ④患者签署知情同意书自愿参加本研究的患者; ⑤饮食、运动、生活方式及降糖方案固定且血糖平稳,治疗前3天及当天空腹血糖变异系数<16%。 ⑥体重指数(BMI)在18.5 kg/m²和40 kg/m²之间。 注:同时符合以上5项的受试者,方可纳入本项研究。

Inclusion criteria

Diagnostic criteria for diabetes mellitus: one of the following: fasting (no caloric intake for at least 8-14 hours) venous or capillary plasma glucose (FPG) >126 mg/dl (7.0 mmol/L); venous plasma glucose >200 mg/dl (11.1 mmol/L) 2 hours after a meal; capillary plasma glucose >220 mg/dl 2 hours after a meal ( 12.2 mmol); random blood glucose >200 mg/d1 (11.1 mmol/L); glycosylated hemoglobin (HbAIc) >6.5%. Diagnostic criteria for metformin-induced diarrhea According to previous high-quality literature studies the possibility of metformin-associated diarrhea should be considered when diarrhea has recently been applied or is being applied to more than 500mg bid of metformin without diarrhea prior to use and other causes of diarrhea are ruled out such as chronic diarrhea food poisoning diabetic autonomic nervous dysfunction ulcerative colitis Crohn's disease and so on. The grading of diarrhea was formulated according to the Guiding Principles for Clinical Research of New Chinese Medicines (for Trial Implementation).

随机方法(请说明由何人用什么方法产生随机序列):

使用SPSS Statistics 26.0生成随机分组序列,序列由不参与研究临床操作的第三方统计人员管理,并保存在密封信封中。纳入患者时,研究人员开启信封,根据序列将患者分配至相应组别。

Randomization Procedure (please state who generates the random number sequence and by what method):

Blood was generated using SPSS Statistics 26.0 to generate randomized grouping sequences which were managed by a third-party statistician not involved in the clinical operations of the study and kept in sealed envelopes. When patients were enrolled the researcher opened the envelopes and assigned patients to the appropriate group based on the sequence.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The clinical center verifies all clinical trial data and keeps and manages them properly. Designate a person responsible for the collection and entry of all data. Upon completion of the trial the clinical center must submit the entered data files and clinical case report Form.CRF) the second for electronic collection and report form (Case report form CRF form).
