埃索美拉唑治疗前后胃食管反流病食管黏膜上皮细胞间隙的变化

目的观察胃食管反流病（GERD）各亚型在埃索美拉唑治疗前后食管黏膜上皮细胞间隙增宽（DIS）的变化。方法19例以烧心为主诉、经内镜检查、24h食管pH监测和质子泵抑制剂治疗试验证实为GERD的患者,接受埃索美拉唑40mg／d治疗2个月。治疗前后内镜检查时在食管齿状线上3～5cm处外观正常黏膜取活检,分别进行组织学及透射电镜检查。15例正常人食管黏膜活检电镜检查作为正常参数。结果2个月治疗后,糜烂性食道炎（6例）、伴有病理性酸反流的NERD（7例）、不伴有病理性酸反流的NERO（6例）DIS恢复正常分别有5例（83．33％）、6例（85．71％）和5例（83．33％）,均伴随烧心症状完全消失。DIS未恢复正常的3例患者中2例烧心症状仍然存在。结论GERD患者经埃索美拉唑治疗2个月后DIS恢复正常伴随症状消失,各组间在DIS恢复上差异无统计学意义。

Changes of intercellular spaces of esophageal epithelium in patients with gastroesophageal reflux disease before and after esomeprazole treatment

OBJECTIVE: To observe the changes of dilated intercellular space (DIS) of esophageal epithelium in different subtypes of gastroesophageal reflux disease (GERD) before and after esomeprazole treatment. METHODS: Nineteen patients with GERD, 6 with erosive esophagitis (EE), 7 with NERD with abnormal acid exposure (NERD pH+), and 6 with NERD with normal acid exposure (NERD pH-), were treated with esomeprazole 40 mg daily for two months. During endoscopy before and after treatment, six biopsy specimens were taken from the apparently normal mucosa 3 - 5 cm above the dentate line in the esophagus to undergo HE staining and histological examination and transmission electron microscopy (TEM). Fifteen normal subjects were used as controls. RESULTS: Two months after the treatment 5 cases (83.33%) in the EE group, 6 cases (85.57%) in the NERD pH+ group, and 5 cases (83.33%) in the NERD pH- group showed a complete recovery of DIS and complete disappearance of the symptom of heartburn. Two of the left three patients who showed incomplete recovery of DIS still had heartburn. CONCLUSION: A complete recovery of DIS 2 months after treatment of esomeprazole is always accompanied by resolution of heartburn symptom. No significant difference in complete recovery of DIS can be found among different GERD subgroups.
