AP&T: 利那洛肽通过脑肠轴信号传导改善肠易激患者临床症状

2020-07-08 MedSci原创 MedSci原创

利那洛肽(Linaclotide)是鸟苷酸环化酶C激动剂,可缓解具有主要便秘(IBS-C)症状的肠易激综合征,但如何改善人类的疼痛尚不清楚。

背景

利那洛肽(Linaclotide)是鸟苷酸环化酶C激动剂,可缓解具有主要便秘(IBS-C)症状的肠易激综合征,但如何改善人类的疼痛尚不清楚。在本项随机临床试验中,研究人员旨在探究利那洛肽和安慰剂对IBS-C患者的传入和传出肠道-肠道信号传导的影响。

 

方法

患有IBS-C(罗马III)和直肠超敏反应的患者被随机分配(2:1)接受利那洛肽(290 µg)或安慰剂治疗10周,并通过肛门直肠电刺激和经颅/经椎体入路进行双向肠道和脑轴评估肛肠磁刺激。通过气囊扩张检查直肠感觉。评估包括腹痛,肠症状和生活质量(QOL)评分。主要结局是直肠皮质和皮质直肠诱发电位的潜伏期。

 

结果

三十九例患者参加;26例接受利那洛肽,13例接受安慰剂。与基线相比,利那洛肽的直肠皮质诱发电位潜伏期(毫秒)显着延长(P1:Δ19±6,P<0.005; N1:Δ20±7,P<0.02),但与安慰剂无关(P1:Δ3±5; N1:Δ4.7±5,P= 0.3)。皮质-肛门直肠和脊髓-肛门直肠的潜伏期不变。最大可容忍直肠体积(cc)的利那洛肽与基线相比显著增加(P<0.001)。使用利那洛肽时腹部疼痛降低(P <0.001)。 与基线和安慰剂相比,利那洛肽的完全自发排便频率增加(P<0.001),IBS-QOL评分得到改善(P = 0.01)。利那洛肽和安慰剂之间的总体缓解率无差异(54%vs 23%,P= 0.13)。

 

结论

利那洛肽可延长从基线开始的肠道-脑信号传导,但与安慰剂相比,传入和传出信号均不受影响。与安慰剂相比,利那洛肽显着改善了直肠超敏反应,IBS-C症状和QOL。这些机制可以解释利那洛肽对IBS-C患者疼痛缓解的影响。
