背景
为了更好地了解生物疗法对克罗恩病(CD)和溃疡性结肠炎(UC)患者的现实影响,研究人员评估了英夫利昔单抗对患者住院率,手术率及支付药物成本产生的作用。

方法
研究人员使用了1995年至2012年间居住在加拿大安大略省的成人UC和CD患者的健康管理数据,进行分段回归分析的间歇时间序列设计来评估英夫利昔单抗对10年以上CD患者及5年以上UC患者住院率、手术率及公共药物支出的影响。

结果
与预期相比,英夫利昔单抗的推广并没有降低CD患者住院率(最后一个观察季度OR1.06,95%置信区间0.811-1.39)以及小肠切除率(OR1.10,95%置信区间0.810-1.50),也没有降低UC患者住院率(OR1.22,95%置信区间1.07-1.39)及结肠切除率(OR0.933,95%置信区间0.54-1.61)。结果与利妥昔单抗使用者的类似,除了利妥昔单抗上市后UC患者住院率大幅下降这一点(OR 0.515,95%CI 0.342-0.777)。引入药物后,CD患者公共药物支出比预期增长了三倍(OR 2.98,95%CI 2.29-3.86),表明CD患者中市场渗透率很高,但UC患者的市场渗透率没有明显变化。

结论
英夫利昔单抗的推广并没有降低炎症性肠病相关的住院率和肠切除率,尽管其在CD患者中市场渗透率很高。CD患者中英夫利昔单抗的错误使用和UC患者中使用不足可能解释了这项研究的结果。

生活在人体肠道内的菌群在人体的代谢、免疫等方面都发挥着至关重要的作用,菌群失衡会导致一系列疾病的发生,比如克罗恩病(CD)和其他形式的炎症性肠病(IBD)等。但这些联系背后的生物学机制仍不清楚。
