AJG:抑酸药雷尼替丁可能会诱发膀胱癌的发生!

N-亚硝基二甲胺 (NDMA) 是一种亚硝胺物质,对哺乳类动物具有致癌性。NDMA诱导的癌症包括很多,其中最容易发生的是膀胱癌。雷尼替丁是一种组胺受体激动剂。

      N-亚硝基二甲胺 (NDMA) 是一种亚硝胺物质,对哺乳类动物具有致癌性。NDMA诱导的癌症包括很多,其中最容易发生的是膀胱癌。雷尼替丁是一种组胺受体激动剂,用于多种适应症包括胃食管反流病和消化性溃疡溃疡的治疗。在美国,它是最常用的 50 种处方药之一。2016年,一项体外研究表明雷尼替丁可以在一定范围内产生NDMA相似的胃部环境。健康志愿者(20-49 岁)服用雷尼替丁后,24 小时尿 NDMA 增加了 400 倍,亚硝胺增加了 5 倍。因此,本项研究旨在探究雷尼替丁的使用是否与膀胱癌风险增加有关。

 

      研究人员通过对芬兰国家数据库的收集进行了一项嵌套病例对照研究。将 1999 年至 2011 年间诊断出的膀胱癌病例和健康对照(基于年龄、性别、登记日期)的患者纳入了本项研究。从患者的医疗处方记录中确定了雷尼替丁、其他组胺 2 受体激动剂和质子泵抑制剂的使用情况。在调整合并症和吸烟后,使用条件逻辑回归计算优势比 (OR) 和 95% 置信区间 (CI)。

 

      本项研究共有 3,260 个病例和 14,037 个对照患者。有证据表明,与不使用雷尼替丁的人相比,使用雷尼替丁的人患膀胱癌的风险明显增加(OR = 1.22;95% CI 1.06–1.40),这在使用雷尼替丁超过 3 年时更为显着(OR = 1.43 ; 95% CI 1.05–1.94)。使用过雷尼替丁的患者(OR = 0.98;95% CI 0.88-1.11)或超过 3 年的使用时间的患者( OR = 0.98; 95% 置信区间 0.80–1.20)其膀胱癌的发生率明显增加。

      本项研究证实使用雷尼替丁尤其是长期使用与膀胱癌风险增加有关。
