Non-Helicobacter pylori, non-NSAID ulcer is relatively common in Western countries. Whether it is a significant problem in the Orient is unclear. The aim of this study was to investigate the incidence of non-H pylori, non-NSAID ulcers presenting with GI bleeding.
A prospective study was done of 1675 consecutive patients presenting with upper GI bleeding over a period of 12 months. Upper endoscopy was performed with biopsy specimens taken from the antrum and body of the stomach for a biopsy urease test (BUT) and histology for detection of H pylori. Exposure to nonsteroidal anti-inflammatory drugs (NSAID) or aspirin within 4 weeks of hospitalization was carefully scrutinized. A 6-week course of treatment with an H2-receptor antagonist was prescribed for patients who did not use an NSAID and had a negative BUT result. Follow-up endoscopy was performed to confirm H pylori status with a BUT and histology. Positive histology at either initial or follow-up endoscopy was used as the standard for diagnosing H pylori infection.
Among 977 patients who were found to have ulcer bleeding, 434 (44%) had exposure to aspirin or an NSAID. Of the 543 non-NSAID users, 431 (79.4%) had a positive BUT and 112 (20.6%) were BUT negative on initial endoscopy. Eighty-nine of 112 patients who were NSAID negative, BUT negative returned for follow-up endoscopy. Forty-nine of 89 (55.1%) were found to have a positive BUT and positive histology at follow-up endoscopy. Only 40 of 977 (4.1%) patients admitted with ulcer bleeding were confirmed to have non-H pylori, non-NSAID ulcers.
Non-H pylori, non-NSAID bleeding ulcer is uncommon. A negative BUT is unreliable for exclusion of H pylori infection during the acute phase of ulcer bleeding.
非幽门螺杆菌、非非甾体抗炎药所致溃疡在西方国家相对常见。在东方它是否是一个重要问题尚不清楚。本研究的目的是调查以消化道出血为表现的非幽门螺杆菌、非非甾体抗炎药所致溃疡的发生率。
对连续12个月内出现上消化道出血的1675例患者进行了一项前瞻性研究。进行上消化道内镜检查,并从胃窦和胃体取活检标本进行活检尿素酶试验(BUT)及组织学检查以检测幽门螺杆菌。仔细审查住院4周内是否使用过非甾体抗炎药(NSAID)或阿司匹林。对于未使用NSAID且BUT结果为阴性的患者,给予6周疗程的H2受体拮抗剂治疗。进行随访内镜检查,通过BUT和组织学检查确认幽门螺杆菌状态。初次或随访内镜检查时组织学阳性被用作诊断幽门螺杆菌感染的标准。
在977例被发现有溃疡出血的患者中,434例(44%)曾使用过阿司匹林或NSAID。在543例未使用NSAID的患者中,431例(79.4%)初次内镜检查时BUT结果为阳性,112例(20.6%)BUT结果为阴性。112例NSAID阴性且BUT阴性的患者中有89例返回进行随访内镜检查。89例中的49例(55.1%)在随访内镜检查时BUT结果为阳性且组织学阳性。在977例因溃疡出血入院的患者中,仅40例(4.1%)被确诊为非幽门螺杆菌、非非甾体抗炎药所致溃疡。
非幽门螺杆菌、非非甾体抗炎药所致出血性溃疡并不常见。在溃疡出血急性期,BUT结果阴性对于排除幽门螺杆菌感染并不可靠。
