Schizophrenia Bulletin:益生菌加膳食纤维补充剂减轻奥氮平诱导的首发未治疗精神分裂症患者的体重增加

益生菌+膳食纤维可安全有效减轻首发未治疗精神分裂症患者抗精神病药物引起的体重增加

第二代抗精神病药(SGAs)被广泛用作治疗精神分裂症的一线药物。然而,抗精神病药引起的体重增加、胰岛素抵抗和代谢紊乱令人担忧这些副作用不仅影响患者对抗精神病药物的依从性,还会导致大量的发病率,如糖尿病、心血管疾病和中风,最终导致过早死亡。奥氮平是一种应用广泛的SGAs,是治疗精神分裂症最有效的抗精神病药物之一。

在第二代抗精神病药物治疗适应症的有效性和青少年耐受性研究中,84%服用奥氮平的参与者在前3个月体重增加超过基线体重的7%。尽管有这些数据,但目前很少有试验检查服用抗精神病药物的患者对体重增加和代谢副作用的预防。

抗精神病药引起的体重增加与肠道菌群组成的改变有关。Schizophrenia Bulletin最近刊发了中南大学湘雅第二医院精神科,国家精神障碍临床研究中心的研究项目,其目的是确定益生菌加膳食纤维对抗精神病药引起的体重增加的影响。

该研究进行了两项序贯随机临床试验。190例首发未治疗精神分裂症患者随机接受奥氮平加益生菌或奥氮平单药治疗12周。在研究2中,60例首发未治疗精神分裂症患者被随机分配接受奥氮平加益生菌和膳食纤维治疗或奥氮平单药治疗12周。

 在研究1中,奥氮平加益生菌治疗与奥氮平单药治疗在4/8/12周的治疗效果比较

在研究1中,两组在体重增加方面没有显著差异。在第12周时,奥氮平+益生菌组的胰岛素抵抗指数(IRI)低于奥氮平单药组(估计平均差异为−0.65,95%可信区间(CI)为−1.10 ~−0.20);p = 0.005)。

在研究2中,奥氮平和益生菌加膳食纤维治疗与奥氮平单药治疗在4/8/12周的疗效比较

在研究2中,在12周时,益生菌加膳食纤维组的体重增加低于奥氮平单药组(估计平均差异为- 3.45 kg, [95% CI,−5.91 -−1.00];p =0.007)。第12周,奥氮平单药组IRI显著增加(平均,1.74;标准差(SD) = 1.11, p<0.001),但在奥氮平+益生菌和膳食纤维组中没有(平均0.47,SD = 2.16, p = 0.35),两组之间的估计平均差异为−0.95 [95% CI,−1.77 -−0.14];p = 0.022)。

 这些结果为益生菌+膳食纤维在减轻首发未治疗精神分裂症患者抗精神病药物引起的体重增加的有效性和安全性提供了支持。
