项目摘要
We propose that diabetic gastroenteropathy (or gastroparesis) represents a failure of a normal meal to switch the stomach from the fasted to the fed state. According to this idea, jejunal feeding restores the normal fed state and switches on the stomach. This study will test this hypothesis by measuring the stomachs response to feeding to a test meal with and without prior infusion of a liquid nutrient directly into the jejunum. This will be done in 12 patients with symptoms of gastroparesis, 12 diabetic patients without digestive problems (diabetic controls) and 12 healthy volunteers (normal controls). Participants will be admitted twice to the research unit for imaging studies. The level of blood glucose will be controlled by an insulin/glucose drip and, under sedation, a feeding tube will be placed into the jejunum by endoscopy. Then, in random order, and without the patient or researcher knowing which preparation is given, either liquid nutrient (food) or water will be infused into the jejunum. After that a standard test meal will be taken. Participants will report digestive symptoms throughout. Magnetic resonance imaging will provide detailed measurements of stomach function. Blood glucose and hormones that control stomach function and appetite will be measured as well. The primary aim of this project is to assess how effective jejunal feeding is in normalizing stomach function and reducing the symptoms of diabetic gastroparesis after a meal. Additionally, by measuring the hormones that switch gastric function between the fasted and the fed states in health and disease, we hope to identify targets for more effective medical treatment of this distressing condition.
我们认为糖尿病性胃肠病(或胃轻瘫)代表了正常膳食未能将胃从禁食状态转换为进食状态。根据这个想法,空肠喂养恢复了正常的进食状态,并打开了胃。本研究将通过测量胃对喂食试验餐的反应来验证这一假设,试验餐有或没有预先将液体营养物直接注入空肠。这将在12名具有胃轻瘫症状的患者、12名没有消化问题的糖尿病患者(糖尿病对照)和12名健康志愿者(正常对照)中进行。参与者将被允许两次进入研究单位进行成像研究。通过胰岛素/葡萄糖滴注控制血糖水平,并在镇静状态下,通过内窥镜将饲管置入空肠。然后,以随机顺序,在患者或研究人员不知道给予哪种制剂的情况下,将液体营养物(食物)或水注入空肠。之后,将进行标准测试餐。参与者将报告整个消化系统症状。磁共振成像将提供胃功能的详细测量。还将测量血糖和控制胃功能和食欲的激素。该项目的主要目的是评估空肠喂养在恢复胃功能和减少餐后糖尿病胃轻瘫症状方面的有效性。此外,通过测量在健康和疾病的禁食和进食状态之间转换胃功能的激素,我们希望确定更有效的药物治疗这种令人痛苦的疾病的目标。
