AP&T: 普瑞巴林在治疗肠易激综合征中疗效分析

2019-02-16 不详 网络

普瑞巴林是钙通道α2δ配体,可改变肠易激综合征(IBS)患者的内脏超敏反应,在治疗IBS中前景广阔,但是目前缺乏具体的临床数据证明,因此本项研究的主要目的是评估普瑞巴林对IBS患者胃肠道症状的疗效。

背景
普瑞巴林是钙通道α2δ配体,可改变肠易激综合征(IBS)患者的内脏超敏反应,在治疗IBS中前景广阔,但是目前缺乏具体的临床数据证明,因此本项研究的主要目的是评估普瑞巴林对IBS患者肠道症状的疗效。

方法
研究人员进行了一项双盲安慰剂对照试验。纳入的受试者是符合IBS罗马III标准且每月出现≥3次疼痛发作的成年人,所有的受试者随机分为普瑞巴林组与安慰组,普瑞巴林口服的剂量为225 mg,试验共持续12周。主要观察终点是平均疼痛肠症状量表(BSS)评分。统计方法采用卡方检验评估疼痛评分的缓解和变化情况。

结果
本项研究共招募了85名患者并随机分组。样本特征为:平均年龄39.4(SD = 14.6); 女性有73名(86%); 其中IBS-D 37名(44%),IBS-M 29名(35%),IBS-C 18名(21%)。普瑞巴林组在9-12周时平均疼痛-BSS评分较低(25 vs 42,P  = 0.008)。与安慰剂相比,普瑞巴林组的整体IBS-BSS严重程度评分较低(26 vs 42,P  = 0.009)。两组之间的充分缓解没有差异(46%VS36%,P  = 0.35)。63%普瑞巴林组患者与45%安慰剂组患者在第12周时的疼痛评分变化≥30(P <0.05)。治疗后IBS-QoL评分在各组之间没有差异。

结论
本项研究表明普瑞巴林在治疗IBS患者的腹痛,腹胀和腹泻中有显着疗效。
