Although 5-aminosalicylate (5-ASA) is the therapy of first choice in ulcerative colitis (UC), some patients cannot tolerate it because of side effects. Previous reports have not investigated whether 5-ASA intolerance is associated with the risk of colectomy.
To investigate the associations between 5-ASA tolerance and colectomy among UC patients METHODS: The data of UC patients who visited any of three hospitals during 2014-2018 in and around Tokyo, Japan, were retrospectively obtained from the medical records. Patients were categorized as (a) tolerant to any 5-ASA compounds ("tolerant to 5-ASA") and (b) patients who were intolerant to one or more 5-ASA compounds leading to refrainment from their further use ("intolerant to 5-ASA"). The association between 5-ASA tolerance and colectomy was examined by Cox proportional hazards model adjusted for sex, age, smoking and extent of colitis.
Of 1788 patients, 1684 were "tolerant to 5-ASA" while 104 were "intolerant to 5-ASA". Colectomy was performed in 43 (2.6%) of the patients tolerant to 5-ASA and 12 (11.5%) of the patients intolerant to 5-ASA. After adjusting for all covariates, the risk of undergoing colectomy was higher in the "intolerant to 5-ASA" group than in the "tolerant to 5-ASA" group (hazard ratio: 4.92; 95% confidence interval: 2.58-9.38).
Patients in whom 5-ASA was discontinued due to intolerance had a higher risk of undergoing colectomy than patients tolerant to their first, second or third 5-ASA compounds.
虽然 5-氨基水杨酸(5-ASA)是溃疡性结肠炎(UC)的首选治疗药物,但由于副作用,有些患者无法耐受。之前的报告并未研究 5-ASA 不耐受是否与结肠切除术的风险相关。
调查溃疡性结肠炎患者中 5-ASA 耐受与结肠切除术之间的关联。
本研究回顾性地从日本东京及其周边地区的三家医院在 2014 年至 2018 年期间就诊的 UC 患者的病历中获取数据。患者分为(a)任何 5-ASA 化合物耐受的患者(“5-ASA 耐受”)和(b)因不耐受一种或多种 5-ASA 化合物而停止使用的患者(“5-ASA 不耐受”)。通过 Cox 比例风险模型,调整性别、年龄、吸烟和结肠炎程度等因素,检验 5-ASA 耐受与结肠切除术之间的关联。
在 1788 名患者中,1684 名患者为“5-ASA 耐受”,104 名患者为“5-ASA 不耐受”。在 5-ASA 耐受的患者中,有 43 例(2.6%)接受了结肠切除术,而在 5-ASA 不耐受的患者中,有 12 例(11.5%)接受了结肠切除术。调整所有协变量后,“5-ASA 不耐受”组患者接受结肠切除术的风险高于“5-ASA 耐受”组(风险比:4.92;95%置信区间:2.58-9.38)。
由于不耐受而停止使用 5-ASA 的患者接受结肠切除术的风险高于耐受其第一、第二或第三种 5-ASA 化合物的患者。
