项目摘要
ABSTRACT: Abdominal pain is the primary driver of morbidity in chronic pancreatitis (CP) and affects
approximately 90% of patients over the course of their disease with devastating effects on quality of life.
Etiology of pain in CP is multi-factorial. Patients with evidence of pancreatic duct obstruction due to stones
and/or strictures are offered invasive treatments such as endotherapy or surgical drainage to relieve pain.
However, response to invasive treatments is unpredictable, and currently no clinical tool is available to identify
patients who will respond to technically successful treatment. The lack of pain response is at least partially due
to supraspinal central sensitization (SCS), a phenomenon of neuropathic and neuroplastic remodeling resulting
from persistent pain stimuli. Quantitative Sensory Testing (QST), an investigative technique of standardized
stimulations to test nociception (the neural signaling that encodes noxious stimuli and the downstream
experience of pain), is used in other pain conditions to differentiate between patient subgroups to guide
treatment. QST has the potential to change the management algorithm of patients with painful CP. Our
preliminary data show that pancreatic QST (P-QST) can phenotype patients with CP into three groups: normal
pain processing, segmental (T10 dermatome at the pancreas) sensitization, and widespread hyperalgesia
(consistent with SCS). In this proposal, we will evaluate the ability of P-QST to predict response to invasive
treatment for painful CP, and to develop a predictive model for individualized prediction of treatment
response. Our specific aims are: Aim 1. Test the predictive capability of pre-treatment P-QST phenotype for
pain improvement following invasive treatment for painful CP. Using pre-procedure P-QST, we will phenotype
150 patients undergoing clinically-indicated invasive treatment for painful CP at UPMC and Johns Hopkins
University. Our primary outcome will be average pain score measured by Numeric Rating Scale at 6 months
post-intervention. Aim 2. Incorporate P-QST with known and suspected patient, disease, and treatment-
related factors to create a model for individualized prediction of response to invasive treatment. Using machine
learning tools, we will develop a model that optimizes the prediction of probability of response to invasive
treatment in individual patients. This will also determine the relative strength of P-QST as an overall predictor
of treatment response. Aim 3. Augment the predictive model (Aim 2) with biochemical inflammatory markers
to assess the potential to increase predictive capability for pain improvement following invasive treatment for
painful CP. The predictive model developed in aim 2 will be further strengthened by incorporating serum
neuroinflammatory markers at baseline. Our findings will be a major step toward development of
individualized prediction of treatment response following invasive treatment for painful CP. They will lay the
foundation for multicenter studies to fully define the role of P-QST in locally invasive and other treatments for
pain management for painful CP.
摘要:腹痛是慢性胰腺炎(CP)发病的主要原因,影响
大约 90% 的患者在病程中对生活质量造成破坏性影响。
CP 疼痛的病因是多因素的。有结石引起胰管阻塞证据的患者
对和/或狭窄进行侵入性治疗,例如内科治疗或手术引流以缓解疼痛。
然而,对侵入性治疗的反应是不可预测的,目前还没有临床工具可以识别
对技术上成功的治疗有反应的患者。缺乏疼痛反应至少部分是由于
脊髓上中枢敏化(SCS),一种神经病理性和神经塑性重塑现象
来自持续的疼痛刺激。定量感官测试(QST),一种标准化的调查技术
测试伤害感受的刺激(编码有害刺激的神经信号和下游
疼痛的经历),用于其他疼痛状况以区分患者亚组以指导
治疗。 QST 有可能改变疼痛性脑瘫患者的治疗方案。我们的
初步数据显示,胰腺 QST (P-QST) 可以将 CP 患者表型分为三组: 正常
疼痛处理、节段性(胰腺 T10 皮刀)敏化和广泛的痛觉过敏
(与 SCS 一致)。在本提案中,我们将评估 P-QST 预测侵入性反应的能力
治疗疼痛性脑瘫,并开发个体化预测治疗的预测模型
回复。我们的具体目标是: 目标 1. 测试治疗前 P-QST 表型的预测能力
疼痛性 CP 侵入性治疗后疼痛改善。使用程序前 P-QST,我们将进行表型分析
150 名患者在 UPMC 和约翰霍普金斯大学接受临床指示的侵入性治疗以治疗疼痛性脑瘫
大学。我们的主要结果是 6 个月时通过数字评定量表测量的平均疼痛评分
干预后。目标 2. 将 P-QST 与已知和疑似患者、疾病和治疗结合起来
相关因素来创建一个模型,用于个体化预测侵入性治疗的反应。使用机器
学习工具,我们将开发一个模型,优化对侵入性反应概率的预测
个别患者的治疗。这也将决定 P-QST 作为整体预测因子的相对强度
治疗反应。目标 3. 使用生化炎症标志物增强预测模型(目标 2)
评估侵入性治疗后提高疼痛改善预测能力的潜力
痛苦的CP。目标 2 中开发的预测模型将通过纳入血清得到进一步加强
基线神经炎症标志物。我们的发现将是朝着发展迈出的重要一步
对疼痛性 CP 侵入性治疗后的治疗反应进行个体化预测。他们将铺设
为多中心研究奠定基础,以全面定义 P-QST 在局部侵入性治疗和其他治疗中的作用
疼痛性 CP 的疼痛管理。
