DESCRIPTION (provided by applicant): Patients with gastroparesis often suffer with chronic gastrointestinal symptoms that are not adequately treated due to both a lack of understanding of the underlying pathophysiology and lack of effective treatments. The participation of Temple University in the NIH/NIDDK Gastroparesis Clinical Research Consortium and the proposed studies will help achieve the broad, long term objectives of improving the diagnosis and treatment of patients with gastroparesis. The PI and Temple University are exceptionally well qualified to continue to be one of the clinical centers in this consortium. Temple University has clinical expertise and an active research program in the evaluation and treatment of patients with gastroparesis. The aims for this renewal of the Gastroparesis Consortium are threefold. First, to complete the ongoing and approved studies initiated by the GpCRC. These studies include NORIG: a randomized trial of nortriptyline vs. placebo for idiopathic gastroparesis; GLUMIT-DG: a pilot study of safety, feasibility and potential efficacy of continuous glucose monitoring and insulin pump therapy in diabetic gastroparesis; APRON: a randomized trial of aprepitant vs. placebo for the relief of nausea in patients with chronic nausea and vomiting of presumed gastric origin; PBG: pathological basis of gastroparesis, a tissue study from full thickness gastric biopsies. Second, to maintain and expand the Gastroparesis Registry. Our aim is to have at least four years of follow-up on patients and with up to nine years for some patients. This will require maintenance of the Registry and continued periodic follow-up visits over the next five years. In addition, we propose recruitment of new patients during continuation of the Gastroparesis Consortium with refinements to existing questionnaires and pathophysiologic measures, as well as new ones. This will allow us to answer questions related to the pathogenesis, severity grading, complications, treatment responses, and clinical outcomes in patients with gastroparesis. Third, to conduct new multicenter studies of gastroparesis investigating the etiology, pathogenesis, diagnosis, and treatment. The PI with his collaborators at Temple University propose a multicenter study aimed at improving the diagnosis of gastric motility disorders. The overall purpose of this project is to develop a single more comprehensive noninvasive test which evaluates several components of gastric motility and, thus, may improve the correlation between dyspeptic symptoms and gastric dysmotility. This will ultimately enable physicians to better target therapy to the underlying gastric pathophysiologic abnormality in patients with gastroparesis.

描述（由申请人提供）：胃轻瘫患者经常患有慢性胃肠道症状，由于缺乏对潜在病理生理的了解和缺乏有效的治疗，这些症状得不到充分的治疗。天普大学参与NIH/NIDDK胃轻瘫临床研究联盟和拟议的研究将有助于实现改善胃轻瘫患者诊断和治疗的广泛、长期目标。PI和天普大学非常有资格继续成为该联盟的临床中心之一。天普大学在胃轻瘫患者的评估和治疗方面拥有临床专业知识和积极的研究项目。胃轻瘫联盟的这一更新的目标是三重的。首先，完成GpCRC发起的正在进行和已批准的研究。这些研究包括NORIG：去甲替林与安慰剂治疗特发性胃轻瘫的随机试验；GLUMIT-DG：持续血糖监测和胰岛素泵治疗糖尿病性胃轻瘫的安全性、可行性和潜在疗效的试点研究；围裙：阿瑞吡坦与安慰剂的随机对照试验，用于缓解疑似胃源性慢性恶心和呕吐患者的恶心；PBG：胃轻瘫的病理基础，来自全层胃活检的组织研究。第二，维持和扩大胃轻瘫登记。我们的目标是对患者进行至少4年的随访，对一些患者进行长达9年的随访。这将需要维持书记官处，并在今后五年内继续定期进行后续访问。此外，我们建议在胃轻瘫联盟继续期间招募新患者，并对现有问卷和病理生理测量进行改进，以及新的测量。这将使我们能够回答与胃轻瘫患者的发病机制、严重程度分级、并发症、治疗反应和临床结果相关的问题。第三，开展新的多中心研究胃轻瘫的病因、发病机制、诊断和治疗。PI和他在天普大学的合作者提出了一项多中心研究，旨在提高胃运动障碍的诊断。该项目的总体目的是开发一种更全面的无创测试，评估胃动力的几个组成部分，从而可能改善消化不良症状与胃动力障碍之间的相关性。这将最终使医生能够更好地针对胃轻瘫患者潜在的胃病理生理异常进行治疗。
