慢性腰痛是世界上最常见、最昂贵、最令人衰弱的疼痛之一。增加对从急性到慢性腰痛转变的机械理解和预测性生物标志物的鉴定可以增强医疗保健提供者进行的临床评估,并能够开发有针对性的治疗方法,以预防和/或更好地管理慢性腰痛。该研究方案旨在确定在腰痛发作时预测慢性腰痛的神经学和转录组学生物标志物。这是一项前瞻性描述性纵向起始队列研究,将随访340名急性腰痛患者和40名健康对照者2年以上。为了分析腰痛的神经生理学和转录组学生物标志物,该方案包括将在腰痛发作后6周内(基线、6、12、24、52周、2年)开始收集的心理和疼痛相关调查数据,以及在另外5个时间点(8、10、16、20周和18个月)远程收集的数据。定量感觉测试和收集血液样本进行RNA测序将在六次亲自访问期间进行。研究结果将描述健康无痛对照组和腰痛患者的神经生理学和转录组学特征的变化,这些患者要么恢复到无痛状态,要么发展为慢性腰痛。
Chronic low back pain is one of the most common, costly, and debilitating pain conditions worldwide. Increased mechanistic understanding of the transition from acute to chronic low back and identification of predictive biomarkers could enhance the clinical assessment performed by health care providers and enable the development of targeted treatment to prevent and/or better manage chronic low back pain. This research protocol was designed to identify the neurological and transcriptomic biomarkers predictive of chronic low back pain at low back pain onset. This is a prospective descriptive longitudinal inception cohort study that will follow 340 individuals with acute low back pain and 40 healthy controls over 2 years. To analyze the neurophysiological and transcriptomic biomarkers of low back pain, the protocol includes psychological and pain-related survey data that will be collected beginning within six weeks of low back pain onset (baseline, 6, 12, 24, 52 weeks, 2 years) and remotely at five additional time points (8, 10, 16, 20 weeks, and 18 months). Quantitative sensory testing and collection of blood samples for RNA sequencing will occur during the six in-person visits. The study results will describe variations in the neurophysiological and transcriptomic profiles of healthy pain-free controls and individuals with low back pain who either recover to pain-free status or develop chronic low back pain.
