中文摘要
项目概要/摘要
胃食管反流病(GERD)基于症状的诊断及其经验性治疗的流行,
高风险住院婴儿的实践差异仍然很大。先前的临床试验数据缺乏生理学-
基于客观的诊断证据和治疗。 GERD 的诊断标准常常不充分,并且
GERD 治疗的相对风险、益处和适应症尚不清楚。因此,知识差距仍然存在,并且
GERD 诊断可能会额外花费 7 万美元,并且每个婴儿需要住院 30 天。客观、有效、
迫切需要循证疗法。几乎所有婴儿都在新生儿重症监护室 (NICU)
有症状时,二十四小时 pH 阻抗 (pH-Imp) 测试可以客观诊断并检测
GERD 的病理生理机制。因此,本研究的总体目标是进行单中心
随机对照试验 (RCT) 旨在检验常见疗法 [自然疗法] 效果的中心假设
成熟、抑酸质子泵抑制剂 (PPI) 或使用添加大米 (AR) 配方的增稠饲料]
在高危婴儿中,根据 pH-Imp 定义的 GERD 标准校正成熟年龄低于 6 个月。
其基本原理是完善新的诊断标准并严格研究随机疗法的影响
实现创造有效、简化、循证和可扩展治疗的长期目标

我们将在以下具体目标中检验这一假设: 目标 1:进行 RCT 来评估和比较
干预措施对主要临床终点(经口喂养的改善和缺乏

英文摘要
PROJECT SUMMARY/ABSTRACT
The prevalence of symptom-based diagnosis of gastroesophageal reflux disease (GERD), its empiric treatment,
and practice variation in high-risk hospitalized infants remain high. Prior clinical trials data lack physiological-
based, objective diagnostic evidence and treatment. GERD is frequently diagnosed by inadequate criteria, and
the relative risks, benefits, and indications of GERD therapies are unclear. Thus, gaps in knowledge persist, and
a GERD diagnosis can cost an extra $70k and 30 days of hospitalization per infant. Objective, effective,
evidence-based therapies are critically needed. As nearly all infants in the neonatal intensive care unit (NICU)
are symptomatic, twenty-four-hour pH-Impedance (pH-Imp) testing can diagnose objectively and detect
mechanisms of pathophysiologic GERD. Therefore, this study’s overall objective is to conduct a single-center
randomized control trial (RCT) to test the central hypothesis that the effects of common therapies [natural
maturation, acid suppression-proton pump inhibitor (PPI), or thickened feeds using added rice (AR) formula] are
distinct in high-risk infants, under six months corrected maturational age with pH-Imp defined criteria for GERD.
The rationale is to refine novel diagnostic criteria and rigorously investigate the impact of randomized therapies
to achieve the long-term goal of creating effective, simplified, evidence-based, and scalable treatment
algorithms.
We will test this hypothesis in the following Specific Aims: Aim 1: Conduct the RCT to evaluate and compare the
efficacy and safety of interventions on the primary clinical endpoint (oral feeding improvement and absence of
troublesome symptoms) to test the working hypothesis that AR is superior to natural maturation and PPI. Aim 2:
Evaluate pH-Imp characteristics and test the working hypotheses that pH-Imp mechanisms are distinct between
a) assigned therapies, and b) clinical success and failure. This project challenges current empiric approaches to
diagnosing and managing GERD in NICU infants by using both a novel combination of pH-Imp metrics and
randomized allocations with targeted stratification (GERD severity and feeding skills) to determine true
therapeutic effects on clinical and mechanistic characteristics. The anticipated outcomes will identify diagnostic
algorithms for determining GERD and effective treatment approaches. In addition, the proposed research is
significant because the knowledge gained will provide the diagnostic basis, framework, and scientific and
economic rationale for future studies to further refine therapies across the pediatric age spectrum. We expect
new benchmarks to develop preventative and therapeutic strategies for GERD, which will positively impact the
quality of life for infants and parents by improving digestive health, overall nutrition, and growth, all relevant to
the mission of NIH (NIDDK).
