项目摘要

The objective of this University of Florida/Advent Health proposal within the Type 1 Diabetes in Acute Pancreatitis Consortium (T1DAPC) is to establish a longitudinal prospective cohort of patients with acute and acute relapsing pancreatitis in order to investigate the incidence, pathophysiology, mechanisms, environmental and biologic risk factors, and predictors of subsequent diabetes. The Diabetes Institute at UF (UFDI) and the Advent Health Translational Research Institute have the resources and capabilities required to perform comprehensive genetic, immunologic, metabolic, histologic, and functional testing to dissect the various mechanisms underlying diabetes following acute pancreatitis. Our proposal addresses four key needs of the T1DAPC. 1) A platform for recruiting large numbers of subjects with acute or acute relapsing pancreatitis. The combined volumes of both health systems approach 2,000 patients admitted with acute pancreatitis yearly. The clinical expertise and existing clinical research support structure is experienced and capable, and the two Institutes have the scientific expertise to help define and support the whole variety of mechanistic studies that will be undertaken; 2) Mechanistic studies of diabetes after acute pancreatitis including a) measuring autoantibody markers of islet autoimmunity after acute pancreatitis (subaim 1a); b) assessing subjects’ type 1 diabetes genetic risk leveraging a custom genotyping array and log additive genetic risk score (subaim 1b); comprehensively characterizing 𝛽𝛽-cell function after acute pancreatitis (subaim 1c); and d) analyzing the imaging features of acute pancreatitis which predict the subsequent development of diabetes (subaim 1d); 3) A consortium opportunity to study human subjects prior to the development of acute pancreatitis, that occurring after endoscopic retrograde cholangiopancreatography (ERCP). UFHealth and AdventHealth perform approximately 2,400 of these procedures yearly, and with the participation of other T1DAPC centers, a sub- cohort could be assembled with biospecimens and imaging data prior to the development of acute pancreatitis, providing a very useful comparison population for future analyses. 4) Collecting a bank of human pancreata from subjects with previous pancreatitis. The Network for Pancreatic Organ donors with Diabetes (nPOD), housed at the UFID, collects and processes transplant-grade pancreata and other tissues from organ procurement organizations (OPOs) across the U.S. and provides them for investigators around the world. We will leverage this infrastructure, along with that of a large local OPO associated with AdventHealth, to obtain organs from individuals with a history of acute pancreatitis. This will provide a unique resource for the T1DAPC, to interrogate the mechanisms of diabetes in tissue, which is not readily accessible in living subjects. This can provide a clinicopathologic correlation for the T1DAPC mechanistic studies. We believe the types of analyses proposed will be necessary for the work of the T1DAPC, and we are able to fully support these aims or related aims selected by the T1DAPC.
佛罗里达大学/Advent Health 急性 1 型糖尿病提案的目标 胰腺炎联盟 (T1DAPC) 旨在建立一个急性和胰腺炎患者的纵向前瞻性队列。 急性复发性胰腺炎的发病率、病理生理学、机制、环境 和生物危险因素以及随后糖尿病的预测因素。佛罗里达大学糖尿病研究所 (UFDI) 和 Advent Health 转化研究所拥有执行任务所需的资源和能力 全面的遗传、免疫学、代谢、组织学和功能测试来剖析各种 急性胰腺炎后糖尿病的机制。我们的提案解决了四个关键需求 T1DAPC。 1)招募大量急性或急性复发性胰腺炎受试者的平台。这 两个卫生系统每年收治的急性胰腺炎患者总数接近 2,000 名。 临床专业知识和现有的临床研究支持结构经验丰富、能力强,并且两个 研究所拥有科学专业知识,可以帮助定义和支持各种机制研究, 将进行; 2) 急性胰腺炎后糖尿病的机制研究,包​​括 a) 测量 急性胰腺炎后胰岛自身免疫的自身抗体标记物(subaim 1a); b) 评估受试者的类型 1 利用定制基因分型阵列和记录附加遗传风险评分(subaim 1b)的糖尿病遗传风险; 全面表征急性胰腺炎后的𝛽𝛽细胞功能(subaim 1c); d) 分析 急性胰腺炎的影像学特征可预测糖尿病的后续发展(subaim 1d); 3)A 财团有机会在急性胰腺炎发生之前研究人类受试者 内镜逆行胰胆管造影(ERCP)后。 UFHealth 和 AdventHealth 执行 每年大约进行 2,400 次此类程序,并且在其他 T1DAPC 中心的参与下, 在急性胰腺炎发生之前,可以用生物样本和影像数据来组装队列, 为未来的分析提供非常有用的比较人群。 4) 收集人类胰腺库 来自既往患有胰腺炎的受试者。糖尿病胰腺器官捐献者网络 (nPOD), 位于 UFID,收集并处理来自器官的移植级胰腺和其他组织 美国各地的采购组织 (OPO) 并为世界各地的调查人员提供这些信息。我们 将利用该基础设施以及与 AdventHealth 相关的大型本地 OPO 的基础设施,以获得 来自有急性胰腺炎病史的个体的器官。这将为我们提供独特的资源 T1DAPC,用于探究组织中糖尿病的机制,这在活体受试者中不易获得。 这可以为 T1DAPC 机制研究提供临床病理学相关性。我们相信以下类型 所提出的分析对于 T1DAPC 的工作是必要的,我们能够全力支持这些目标 或 T1DAPC 选择的相关目标。
