摘要

最近的研究证明,脊柱旁肌肉的结构变化与椎间盘退变(IDD)有关,腰背痛(LBP)无处不在,并可能受炎症过程的调节。本研究的目的是调查健康人与腰椎间盘突出症(LDH)患者、有腰背痛与无腰背痛的腰椎间盘突出症患者脊柱旁肌肉的结构变化差异,并确定其与炎症标志物表达之间的联系。这项前瞻性队列研究对肌肉横截面积(CSA)和脂肪变性进行了测量。基因表达采用 qPCR 方法进行量化。采用独立t检验、Chi-square和Spearman相关性来评估结构变化、炎症标志物表达和临床结果之间的联系。与非 LBP 组相比,LBP 组 MM 的脂肪浸润明显增加。在 MM 中,高脂肪浸润组的 TNF-α(TNF-α)是低脂肪浸润组的 28 倍。MM中TNF-α和IL-1β的表达与MM的功能性CSA和脂肪变性呈中度相关,而MM的功能性CSA和脂肪变性与临床结果呈中度相关。研究结果支持了IDD与局部MM炎症状态失调有关的假设,这为脊柱旁肌肉的炎症失调可能对组织健康和LBP症状产生广泛影响提供了初步证据。

Links among MRI features in paraspinal muscles, inflammatory processes, and related back pain in patients with lumbar disc herniation

Links among MRI features in paraspinal muscles, inflammatory processes, and related back pain in patients with lumbar disc herniation

Background

Recent studies have provided evidence that structural changes in paraspinal muscles are associated with intervertebral disc degeneration (IDD), ubiquitous with low back pain (LBP), and potentially thought to be regulated by inflammatory processes. However, the links remain unclear.

Objective

The aims of this study were to investigate structural changes in paraspinal muscles that differed in healthy and lumbar disc herniation (LDH) patients, and LDH patients with and without LBP, and to determine the link with the expression of inflammatory marker(s).

Methods

Cross-sectional areas (CSAs) and fatty degeneration of muscles were measured in this prospective cohort study. Multifidus muscle (MM) tissue was procured from included individuals undergoing surgery. Gene expression was quantified using qPCR assays. Independent t-test, Chi-square, and Spearman correlation were used for evaluating the links among structural changes, expression of inflammatory markers, and clinical outcomes.

Results

Functional CSA and fatty degeneration of MM were larger in healthy group than LDH group. A significant increase in fat infiltration in MM in LBP group than in non-LBP group. TNF-alpha (TNF-α) was 28-fold greater in high-fat infiltration group than low-fat infiltration group within MM. Expression of TNF-α and IL-1β in MM was moderately correlated with functional CSA and fatty degeneration of MM, which was moderately correlated with clinical outcomes.

Conclusions

Results support the hypothesis that IDD is associated with dysregulation of inflammatory state of local MM, which provides initial evidence that inflammatory dysregulation in paraspinal muscles has the potential for a broad impact on tissue health and LBP symptoms.
