未经证实:镰状细胞病(SCD)患者,强烈的慢性和急性疼痛发作会导致负面的身体和情绪体验,但是这些背后的因素,以及它们的相互作用,不是很了解。精氨酸加压素受体1a基因(AVPR1A)单核苷酸多态性rs10877969先前与急性疼痛和压力相关疼痛有关。在这项研究中,我们测试了这个SNP之间的关联,热和压力疼痛阈值,临床疼痛,以及SCD患者的压力。
UNASSIGNED:150名参加SCD的成年人完成了疼痛强度测量(平均疼痛强度,API)和感知压力问卷(PSQ)。热和压力疼痛阈值数据来自定量感觉测试(QST),并获得rs10877969个基因型。
未经评估:在调整了年龄和性别的模型中,rs10877969基因型之间,我们观察到热(冷,p=0.66;热,p=0.91)和机械(压力,p=0.33)疼痛阈值。rs10877969与API(p=0.09)的关联是临界的,但与PSQ无关(p=0.51)。临床疼痛与环境应激的相关性显著,r=0.18,p=0.024,基因型与PSQ的交互作用不显著(p=0.63)。
UNASSIGNED:临床和实验性疼痛与rs10877969基因型无显著相关。rs10877969基因型并未减轻该人群中环境应激与临床疼痛之间的相关性。然而,在SCD中,保护性T等位基因对平均疼痛评分有影响的趋势需要进一步探索该SNP/基因在SCD中的应用.
UNASSIGNED: In patients with sickle cell disease (SCD), negative physical and emotional experiences result from intense chronic and acute pain episodes, but factors underlying these, and their interactions, are not well understood. The arginine vasopressin receptor 1a gene (AVPR1A) single nucleotide polymorphism rs10877969 has been previously associated with aspects of acute pain and stress related pain. In this study, we tested for associations between this SNP, thermal and pressure pain thresholds, clinical pain, and stress in people with SCD.
UNASSIGNED: 150 adults enrolled with SCD completed pain intensity measures (Average Pain Intensity, API) and the Perceived Stress Questionnaire (PSQ). Thermal and pressure pain threshold data were available from quantitative sensory testing (QST), and rs10877969 genotypes were obtained.
UNASSIGNED: In models adjusted for age and gender, between rs10877969 genotypes, we observed no significant differences in thermal (cold, p = 0.66; heat, p = 0.91) and mechanical (pressure, p = 0.33) pain thresholds. The association of rs10877969 with API (p = 0.09) was borderline, but non-significant with PSQ (p = 0.51). The correlation between clinical pain and environmental stress was significant, r = 0.18, p = 0.024, however, the interaction of genotype and PSQ was not significant (p = 0.63).
UNASSIGNED: Clinical and experimental pain were not significantly associated with the rs10877969 genotype. The rs10877969 genotype did not moderate the correlation between environmental stress and clinical pain in this population. However, a trend toward a protective T allele effect on average pain rating in SCD warrants future exploration of this SNP/gene in SCD.
