摘　　要：目的:探索5-羟色胺转运体(5-hydroxytryptamine transporter,5-HTT)基因多态性与抗抑郁剂治疗广泛性焦虑障碍(generalized anxiety disorder,GAD)疗效的关联性。方法:188例符合DSM-IV广泛性焦虑障碍诊断标准的患者接受艾司西酞普兰(n=117)或者文拉法辛缓释剂(n=71)治疗8周,疗效判定以汉密尔顿焦虑量表(hamilton anxiety rating scale,HAMA)评分减分率及HAMA评分来评定。对所有患者及169例正常对照组接受5-HTT基因多态性检测。结果:5-HTT各基因型(SS、LS、LL)及等位基因(S、L)在GAD病例组和对照组的分布差异无统计学意义(P>0.05)。5-HTT各基因型患者基线时HAMA评分差异无统计学意义(F=0.052,P=0.949)。所有患者中SS、LS、LL基因型治疗后HAMA减分值差异无统计学意义(F=0.748,P=0.475)。艾司西酞普兰治疗组SS、LS、LL基因型治疗后HAMA减分值差异无统计学意义(F=0.210,P=0.811)。文拉法辛缓释剂治疗组SS、LS、LL基因型治疗后HAMA减分值差异有统计学意义(F=3.505,P=0.036),LL基因型患者HAMA减分值显著高于SS和LS基因型。结论:5-HTT基因多态性与GAD发病的易感性之间可能无直接关系。5-HTT基因多态性和艾司西酞普兰的疗效不相关,但LL基因型的GAD患者接受文拉法辛缓释剂治疗的疗效可能优于SS和LS基因型。AIM:To explore the relationship between 5-HTT gene polymorphism and treatment response in the treatment of generalized anxiety disorder(GAD)patients with anti-depressants.METHODS:A total of 188 GAD patients who met the criteria of DSM-IV were treated with escitalopram(n=117)or venlafaxine(n=71)randomly for 8 weeks.The serum 5-HTT gene polymorphisms of all patients were detected,while Hamilton Anxiety Rating Scale(HAMA)scores were measured at baseline and after 8 weeks of treatment.A remission was defined as HAMA≤7 after 8 weeks'treatment,and a response was defined as HAMA reduction rate≥50%.The serum 5-HTT gene polymorphisms of all healthy controls who well matched with GAD patients were also detected.RESULTS:There were no significant differences of the 5-HTT polymorphism genotypes and alleles between GAD and controls(P>0.05).Baseline HAMA in different 5-HTT genotype had no significant differences(F=0.052,P=0.949).The reduction of HAMA in SS,LS,LL genetypes after the treatment had no significant difference(F=0.748,P=0.475).The reduction of HAMA in SS,LS,LL genetypes after the treatment of escitalopram had no significant difference(F=0.210,P=0.811).The reduction of HAMA in SS,LS,LL genetypes after the treatment of venlafaxine had significant difference(F=3.505,P=0.036),the reduction of HAMA in LL genetype were higher than that in SS and LS genetypes.CONCLUSION:The 5-HTT polymorphism maybe was not associated with GAD and antidepressant clinical efficacy in GAD patients,but the efficacy of the LL genetype may be better than LS and SS genetypes after the treatment of venlafaxine.
