Abstract

BACKGROUND

To investigate the possible association between the serotonin transporter gene (5-HTTLPR) and rs 25531 polymorphism and the susceptibility and the pain severity in Trigeminal Neuralgia patients.

METHODS

A total of 244 TN patients and 280 age and sex matched healthy volunteer were recruited. 5-HTTLPR and rs 25531 genotyping were performed. All patients received the carbamazepine treatment and the treatment response was evaluated at 6 months.

RESULTS

The genotype distribution of 5-HTTLPR between TN patients and controls were significantly different. The TN Patients had a higher prevalence of short-short genotype than controls. The short-short genotype carriers are also significantly associated with higher pain severity and poorer carbamazepine treatment response compared to the long-long genotype carriers. In contrast, the rs 25531 polymorphism was not associated with the susceptibility to TN, neither with the pain severity and the treat response to carbamazepine.

CONCLUSION

The 5-HTTLPR polymorphism is associated with the susceptibility to TN and pain severity of TN.

摘要

背景

为了探究 5-羟色胺转运体基因(5-HTTLPR)和 rs25531 多态性与三叉神经痛(TN)患者的易感性和疼痛严重程度之间的可能关联。

方法

共纳入 244 例 TN 患者和 280 名年龄和性别相匹配的健康志愿者。进行 5-HTTLPR 和 rs25531 基因分型。所有患者均接受卡马西平治疗,并在 6 个月时评估治疗反应。

结果

TN 患者与对照组之间 5-HTTLPR 的基因型分布存在显著差异。TN 患者的短-短基因型的发生率明显高于对照组。与长-长基因型携带者相比,短-短基因型携带者的疼痛严重程度更高,且对卡马西平的治疗反应更差。相比之下,rs25531 多态性与 TN 的易感性、疼痛严重程度和卡马西平治疗反应均无相关性。

结论

5-HTTLPR 多态性与 TN 的易感性和疼痛严重程度相关。
