全身炎症和疼痛敏感性可能有助于慢性疼痛的发展和维持。我们研究了华盛顿大学双胞胎登记处 198 名女性双胞胎的 C 反应蛋白 (CRP) 测量的全身炎症与冷痛敏感性之间的关系。我们还探讨了家庭因素在这种关系中的潜在作用。使用广义估计方程的线性回归模型检查了整体和配对内的关联。在调整年龄、体重指数、达到疼痛阈值或耐受性的时间以及临床疼痛状态后,较高水平的 CRP 与较高的疼痛阈值 (p = 0.02) 和耐受性 (p = 0.03) 的疼痛敏感性评级相关。在控制家庭因素的配对内分析中,关联的程度保持不变。 CRP 和疼痛敏感性之间的联系可能是由于非共享的环境因素造成的。 CRP 和疼痛敏感性可以作为慢性疼痛和其他炎症性疾病的潜在生物标志物进行检查。
Systemic inflammation and pain sensitivity may contribute to the development and maintenance of chronic pain conditions. We examined the relationship between systemic inflammation as measured by C-reactive protein (CRP), and cold pain sensitivity in 198 female twins from the University of Washington Twin Registry. We also explored the potential role of familial factors in this relationship. Linear regression modeling with generalized estimating equations examined the overall and within-pair associations. Higher levels of CRP were associated with higher pain sensitivity ratings at pain threshold (p = 0.02) and tolerance (p = 0.03) after adjusting for age, body mass index, time to reach pain threshold or tolerance, and clinical pain status. The magnitude of the associations remained the same in within-pair analyses controlling for familial factors. The link between CRP and pain sensitivity may be due to non-shared environmental factors. CRP and pain sensitivity can be examined as potential biomarkers for chronic pain and other inflammatory conditions.
