Abstract

Background: Spinal cord (SC) atrophy is a key imaging biomarker of progressive multiple sclerosis (MS). Progressive MS is more common in men and postmenopausal women.

Objective: Investigate the impact of sex and menopause on SC measurements in persons with MS (pwMS).

Methods: In pwMS and age- and sex-matched controls, upper cervical SC area from brain MRI (UCC_brain) was obtained. Impact of sex and menopause on UCC_brain (adjusted for total intracranial volume) and its association with progression and disability, including MS functional composite (MSFC), were investigated.

Results: UCC_brain was smaller in pwMS (n = 118, 51.4 ± 5.3 mm²) than controls (n = 118, 54.2 ± 4.4 mm², p < 0.001) and inversely correlated with older age in pwMS (r = -0.24, p = 0.010) but not in controls (r = -0.025, p = 0.786). In 173 pwMS (413 brain MRIs), UCC_brain was smaller in men (49.5 ± 5.9 mm²) than women (51.6 ± 5.5 mm², p = 0.001), postmenopausal women (49.4 ± 5.6 mm²) than premenopausal women (52.9 ± 4.1 mm², p < 0.001), and progressive (47.5 ± 5.6 mm²) than relapsing MS (52.1 ± 5.2 mm², p < 0.001). UCC_brain also correlated with disease duration (r = -0.39, p < 0.001), 9-hole peg test (r = -0.26, p = 0.005), and severe ambulatory disability (Expanded Disability Status Scale ⩾6) (r = -0.27, p < 0.001).

Conclusion: UCC_brain, a biomarker of progressive MS, is inversely associated with age, disease duration, male sex, and menopause, highlighting the potential impact of sex and hormones on neurodegeneration in MS.

多发性硬化症的上颈脊髓萎缩：性别、更年期和神经变性。

背景：脊髓（SC）萎缩是进行性多发性硬化症（MS）的关键影像生物标志物。进行性多发性硬化症在男性和绝经后女性中更为常见。目的：探讨性别和更年期对多发性硬化症（pwMS）患者SC测量的影响。方法：在pwMS和年龄、性别匹配的对照组中，通过脑MRI （UCCbrain）获取上颈椎SC区。研究了性别和更年期对UCCbrain（经颅内总容积调整）的影响及其与进展和残疾（包括MS功能复合（MSFC））的关系。结果：pwMS患者UCCbrain （n = 118, 51.4±5.3 mm2）小于对照组（n = 118, 54.2±4.4 mm2, p < 0.001），与年龄呈负相关（r = -0.24, p = 0.010），而对照组无相关（r = -0.025, p = 0.786）。在173张pwMS（413张脑mri）中，男性UCCbrain（49.5±5.9 mm2）小于女性（51.6±5.5 mm2, p = 0.001），绝经后女性（49.4±5.6 mm2）小于绝经前女性（52.9±4.1 mm2, p < 0.001），进行性（47.5±5.6 mm2）小于复发性MS（52.1±5.2 mm2, p < 0.001）。UCCbrain还与疾病持续时间（r = -0.39, p < 0.001）、9孔栓试验（r = -0.26, p = 0.005）和严重的动态残疾（扩展残疾状态量表大于或等于6）（r = -0.27, p < 0.001）相关。结论：UCCbrain是进展性MS的生物标志物，与年龄、病程、男性和绝经期呈负相关，突出了性别和激素对MS神经退行性变的潜在影响。
