关于皮质醇和疼痛敏感性之间的联系,人们知之甚少。我们研究了198对女性双胞胎的唾液皮质醇与冷痛敏感指数的关系,并探讨了家庭混杂的作用。收集三天的唾液样本以测定皮质醇水平,并使用冷加压试验收集疼痛等级以及到达阈值和耐受性的时间。使用广义估计方程的线性回归模型检验了总体和配对内的关联。皮质醇的日变化越小,阈值(p=0.02)和耐受性(p<0.01)的疼痛等级越高。日变化与阈值疼痛分级和耐受性的关系受家族因素(即遗传和共同环境)的影响最小。了解HPA轴调节失调和疼痛敏感性之间潜在的遗传和非遗传机制可能有助于预防慢性疼痛的发生和维持。
There is a dearth of knowledge about the link between cortisol and pain sensitivity. We examined the association of salivary cortisol with indices of cold pain sensitivity in 198 female twins and explored the role of familial confounding. Three-day saliva samples were collected for cortisol levels and a cold pressor test was used to collect pain ratings and time to threshold and tolerance. Linear regression modeling with generalized estimating equations examined the overall and within-pair associations. Lower diurnal variation of cortisol was associated with higher pain ratings at threshold (p = 0.02) and tolerance (p < 0.01). The relationship of diurnal variation with pain ratings at threshold and tolerance was minimally influenced by familial factors (i.e., genetics and common environment). Understanding the genetic and non-genetic mechanisms underlying the link between HPA axis dysregulation and pain sensitivity may help to prevent chronic pain development and maintenance.
