  美国学者Kueiyu Joshua Lin等,最近研究发现,与不使用质子泵抑制剂(PPI)相比,在总人群和进行抗血栓或抗炎治疗的患者中使用PPI,能降低的上消化道出血(UGIB)的风险;并且UGIB的风险降低在组胺2型受体拮抗剂(H2RA)使用者中小于PPI使用者。该研究发表于《胃肠病学》(Gastroenterology)杂志。

  研究者们在总人群和正在进行抗血栓或抗炎治疗的患者中,研究了UGIB的不同预防策略。

  研究人员采用健康改善网络的英国初级保健数据库,实施了一个以人口为基础的、嵌套病例对照研究;从2000年到2007年,选择了2049例UGIB和20,000例对照。通过采用多变量罗杰斯(logistic)回归,比较目前使用(定义为索引日期的30天内使用)与一年未使用胃保护剂的不同情况,估算UGIB的相对风险(RR)与多种胃保护剂是否相关。

  UGIB校正过的RR,与PPI超过1个月的目前使用的相关性,在接受小剂量乙酰水杨酸(ASA)的患者中为0.58【95%可信区间(CI)为0.42~0.79】,氯吡格雷为0.18(95% CI,0.04~0.79),双重抗血小板治疗为0.17(95% CI,0.04~0.76),华法林为0.48(95% CI,0.22~1.04),非甾体抗炎药为0.51(95% CI,0.34~0.78)。使用组胺2型受体拮抗剂(H2RA)治疗的相应估测更不稳定,但倾向于较小的幅度。在总人群中,PPI的使用与未使用相比,和UGIB较低的风险相关(RR,0.80;95% CI,0.68~0.94);在H2RA或硝酸盐中则没有观察到相应的降低。
