【摘要】 目的 研究肝源性潰瘍(HU)患者幽門螺桿菌(Hp)感染情況及影響因素。方法 選取確診的80例HU患者作為HU組, 80例肝硬化無消化性潰瘍患者作為肝硬化無潰瘍組, 80例功能性消化不良(FD)患者作為FD組, 通過快速尿素酶試驗(RUT)或14C尿素呼氣試驗來判斷Hp感染。比較三組患者Hp陽性情況;不同肝功能分級、不同食管靜脈曲張程度HU患者Hp陽性情況。結(jié)果 HU組患者Hp陽性率為80.00%, 明顯高于肝硬化無潰瘍組的60.00%、FD組的43.75%, 差異具有統(tǒng)計學(xué)意義(P<0.05)。80例HU患者中, 肝功能A級患者Hp陽性率為79.17%(38/48), 與肝功能B級的81.25%(26/32)比較差異無統(tǒng)計學(xué)意義(P>0.05)。80例HU患者中, 輕度食管靜脈曲張患者Hp陽性率為88.89%(40/45), 高于中重度食管靜脈曲張患者的68.57%(24/35), 差異有統(tǒng)計學(xué)意義(P<0.05)。結(jié)論 HU患者有較高的Hp感染率, Hp感染是HU患者發(fā)病原因之一, 且Hp感染與HU患者門脈壓有關(guān), 與肝功能分級無關(guān)。

【Abstract】 Objective? ?To study Helicobacter pylori (Hp) infection and its influencing factors in patients with hepatogenic ulcer (HU). Methods? ?There were 80 confirmed HU patients selected as the HU group,?80 patients with cirrhosis without peptic ulcers as the cirrhosis without ulcers group, and 80 patients with functional dyspepsia (FD) as the FD group. HP infection was determined by rapid urease test (RUT) or 14C urea breath test. The Hp-positive status and Hp-positive status of HU patients with different liver function grades and different degrees of esophageal varices were compared among three groups of patients. Results? ?The Hp-positive rate of HU group was 80.00%, which was obviously higher than that of cirrhosis without ulcers group 60.00% and FD group 43.75%, and the difference was statistically significant (P<0.05). In 80 HU patients, the HP-positive?rate was 79.17% (38/48) in patients with grade A liver function, and there was no statistically significant difference compared with 81.25% (26/32) in patients with grade B liver function (P>0.05). In 80 HU patients, the?HP-positive rate of mild esophageal varices was 88.89% (40/45), which was higher than that of moderate and severe esophageal varices 68.57% (24 / 35), and the difference was statistically significant (P<0.05). Conclusion? There is a in HU patients. Hp infection is one of the causes of HU patients, and Hp infection is correlated with portal pressure in HU patients and has nothing to do with liver function grades.
【Key words】 Hepatogenic ulcer; Pathogenesis; Helicobacter pylori
肝源性潰瘍(hepatogenic ulcer, HU)是指在肝硬化基礎(chǔ)上發(fā)生的消化性潰瘍, 是肝硬化上消化道出血的常見原因, 其癥狀常為肝硬化本身表現(xiàn)所掩蓋, 多表現(xiàn)為無規(guī)律的上腹痛、反酸、噯氣、腹脹、納差等, 病程長, 不易愈合, 容易漏診、誤診, 一般的抑酸治療難以取得令人滿意的效果, 長期以來是臨床治療的難題。HU的發(fā)病機制和普通消化性潰瘍不完全相同, 與門靜脈高壓、肝功能損害等因素有關(guān), 但確切機制尚不清楚, 尤其關(guān)于幽門螺桿菌(Hp)是否是HU的病因, 目前還存在很大爭議[1-3]。為此, 本文對2010年1月~2019年12月收治的經(jīng)確診的80例HU患者、肝硬化非潰瘍患者及FD患者進行Hp感染情況調(diào)查, 以期闡明二者的相關(guān)性, 現(xiàn)報告如下。
對HU患者Hp感染的影響因素進行分析, 本研究觀察了HU患者的肝功能及食管靜脈曲張情況對Hp的影響, 結(jié)果顯示, Hp感染與HU患者的肝功能分級無明顯相關(guān), 而與其食管靜脈曲張程度呈負相關(guān), 說明Hp感染與HU患者的門脈高壓有關(guān), 與肝功能分級無關(guān), 此結(jié)果與以前有關(guān)研究一致[9-11]。
綜上所述, HU患者有較高的Hp感染率, Hp感染是HU患者發(fā)病原因之一, 且Hp感染與HU患者門脈壓有關(guān), 與肝功能分級無關(guān)。
