AIM: To investigate the proportion of patients with moderate-severe erosive esophagitis (EE) who will have Barrett's esophagus (BE) after healing of inflammation.
METHODS: Patients with EE of Los Angeles (LA) class B, C and D who underwent follow-up endoscopy documenting complete mucosal healing.
RESULTS: A total of 86/169 patients were suspected of having BE (38 before healing and 48 after healing of EE) and, 46/86 eventually had the histological confirmation. At index esophago-gastro-duodenoscopy (EGD), BE was suspected in 38/169 (22%), and ultimately, histologically confirmed in 20 of these. In 11 patients where biopsies were performed in the presence of inflammation, BE was detected in 2 and missed in 5 (including 2 dysplasias). In 131/169 patients (77.5%), BE was not suspected at index EGD. After healing of EE though, 48 patients had suspicion of BE who underwent biopsies, and in 26 of these histology was positive for BE. The length of inflammation had a linear correlation with the length of BE (P = 0.01). Out of multiple variables to predict BE, only the suspicion at index endoscopy was statistically significant (P = 0.01).
CONCLUSION: BE was seen in 46/169 (27%) patients with EE of LA class B, C and D. The length of EE can predict the length of underlying BE segment.Even when suspected, BE and associated dysplasia can be missed in the presence of inflammation; therefore, repeat evaluation should be considered after complete healing of esophagitis. 相似文献

BACKGROUND & AIMS: There are limited data comparing the effectiveness of available proton pump inhibitors (PPIs) in erosive esophagitis (EE). We performed a meta-analysis to calculate the pooled effect of esomeprazole on healing rates, symptom relief, and adverse events versus competing PPIs in EE. METHODS: We performed a structured electronic search of MEDLINE and EMBASE and reviewed published abstracts to identify English-language, randomized clinical trials from 1995-2005, comparing rates of endoscopic healing, symptom relief, and adverse events with esomeprazole versus alternative PPIs in the treatment of gastroesophageal reflux disease (GERD)/EE. We then performed meta-analysis to compare the relative risk (RR) of EE healing, symptom relief, and adverse events between study arms and calculated the absolute risk reduction and number needed to treat (NNT) for each outcome. RESULTS: Meta-analysis was performed on 10 studies (n=15,316). At 8 weeks, there was a 5% (RR, 1.05; 95% confidence interval, 1.02-1.08) relative increase in the probability of healing of EE with esomeprazole, yielding an absolute risk reduction of 4% and NNT of 25. The calculated NNTs by Los Angeles grade of EE (grades A-D) were 50, 33, 14, and 8, respectively. Last, esomeprazole conferred an 8% (RR, 1.08; 95% confidence interval, 1.05-1.11) relative increase in the probability of GERD symptom relief at 4 weeks. CONCLUSIONS: As compared with other PPIs, esomeprazole confers a statistically significant improvement, yet, clinically, only a modest overall benefit in 8-week healing and symptom relief in all-comers with EE. The clinical benefit of esomeprazole appears negligible in less severe erosive disease but might be important in more severe disease. 相似文献

AIM: To clarify whether there is any difference in the symptom relief in patients with reflux esophagitis following the administration of four Proton pump inhibitors (PPIs). METHODS: Two hundred and seventy-four patients with erosive reflux esophagitis were randomized to receive 8 wk of 20 mg omeprazole (n = 68), 30 mg of lansoprazole (n = 69), 40 mg of pantoprazole (n = 69), 40 mg of esomeprazole (n = 68) once a day in the morning. Daily changes in heartburn and acid reflux symptoms in the first 7 d of administration were assessed using a six-point scale (0: none; 1: mild; 2: mild-moderate; 3: moderate; 4: moderate-severe; 5: severe). RESULTS: The mean heartburn score in patients treated with esomeprazole more rapidly decreased than those receiving other PPI. Complete resolution of heartburn was also more rapid in patients treated with esomeprazole for 5 d compared with omeprazole (P = 0.0018, P = 0.0098, P = 0.0027, P = 0.0137, P = 0.0069, respectively), lansoprazole (P = 0.0020, P = 0.0046, P = 0.0037, P = 0.0016, P = 0.0076, respectively), and pantoprazole (P = 0.0006, P = 0.0005, P = 0.0009, P = 0.0031, P = 0.0119, respectively). There were no significant differences between the four groups in the rate of endoscopic healing of reflux esophagitis at week 8. CONCLUSION: Esomeprazole may be more effective than omeprazole, lansoprazole, and pantoprazole for the rapid relief of heartburn symptoms and acid reflux symptoms in patients with reflux esophagitis. 相似文献

OBJECTIVES: Esomeprazole, the S isomer of omeprazole, has been shown to have higher healing rates of erosive esophagitis than omeprazole. This study compared esomeprazole with lansoprazole for the healing of erosive esophagitis and resolution of heartburn. METHODS: This United States multicenter, randomized, double blind, parallel group trial was performed in 5241 adult patients (intent-to-treat population) with endoscopically documented erosive esophagitis, which was graded by severity at baseline (Los Angeles classification). Patients received 40 mg of esomeprazole (n = 2624) or 30 mg of lansoprazole (n = 2617) once daily before breakfast for up to 8 wk. The primary efficacy endpoint was healing of erosive esophagitis at week 8. Secondary assessments included proportion of patients healed at week 4, resolution of investigator-recorded heartburn, time to first and time to sustained resolution of patient diary-recorded heartburn, and proportion of heartburn-free days and nights. RESULTS: Esomeprazole (40 mg) demonstrated significantly higher healing rates (92.6%, 95% CI = 91.5-93.6%) than lansoprazole (30 mg) (88.8%, 95% CI = 87.5-90.0%) at week 8 (p = 0.0001, life-table estimates, intent-to-treat analysis). A significant difference in healing rates favoring esomeprazole was also observed at week 4. The difference in healing rates between esomeprazole and lansoprazole increased as baseline severity of erosive esophagitis increased. Sustained resolution of heartburn occurred faster and in more patients treated with esomeprazole. Sustained resolution of nocturnal heartburn also occurred faster with esomeprazole. Both treatments were well tolerated. CONCLUSIONS: Esomeprazole (40 mg) is more effective than lansoprazole (30 mg) in healing erosive esophagitis and resolving heartburn. Healing rates are consistently high with esomeprazole, irrespective of baseline disease severity. 相似文献

Abstract Objective. Asymptomatic erosive esophagitis (EE) is incidentally found during endoscopy for health screening. The authors have aimed to investigate the prevalence of asymptomatic EE in subjects undergoing health checkups and factors associated with symptom presentation of EE. Methods. Among the consecutive 13,342 adults who underwent esophagogastroduodenoscopy in health checkup programs of Ajou University Hospital from May 2010 to April 2011, 8840 subjects (5683 men and 3157 women; median age, 45 years) who met the enrollment criteria were included in the analysis. They completed a questionnaire that evaluated smoking, medication history, anxiety, depression, esophagopharyngeal symptoms, and dyspeptic symptoms. The mucosal damage of the esophagus was assessed using the Los Angeles classification system. Individuals who had EE but no esophagopharyngeal symptoms were classified into the asymptomatic EE group. Results. A total of 768 subjects were diagnosed with gastroesophageal reflux disease based on the occurrence of heartburn and/or acid regurgitation at least once a week. The prevalence of symptomatic and asymptomatic EE in 8840 subjects was 4.3% and 3.3%, respectively. About 43% of individuals with EE did not exhibit any esophagopharyngeal symptoms. Male gender and postprandial distress syndrome were independently associated with asymptomatic EE. Male gender, current smoking, anxiety, epigastric pain syndrome (EPS), and postprandial distress syndrome were independently associated with symptomatic EE. Compared with the asymptomatic EE group, anxiety and EPS were independent factors associated with symptomatic EE. Conclusions. Asymptomatic EE is common in subjects undergoing a health checkup. The coexistence of anxiety or EPS appears to be the predictors for the symptom presentation of EE. 相似文献

BACKGROUND/AIMS: An intravenous formulation of esomeprazole has been developed for use in patients where oral administration is not appropriate. This study evaluated safety after 1 and 4 weeks, and efficacy after 4 weeks' esomeprazole 40 mg once daily treatment, administered via an intravenous injection, intravenous infusion or orally, in patients with erosive esophagitis. METHODS: In this double-blind, multi-centre study, patients with endoscopically confirmed erosive esophagitis (Los Angeles grade A-D) were randomized to receive 1 week's treatment of esomeprazole 40 mg once daily, via a 3-min injection, a 30-min infusion or orally, followed by 3 weeks of open treatment with oral esomeprazole 40 mg once daily. Safety variables were evaluated following 1 and 4 weeks' esomeprazole treatment. Healing rates at 4 weeks were estimated. RESULTS: Intravenous and oral esomeprazole were equally well tolerated during the first week, and after 4 weeks' treatment. The 3 treatment groups showed similar levels of healing following 4 weeks' treatment with esomeprazole (injection + oral: 79.7%; infusion + oral: 80.2%; oral alone: 82.6%). CONCLUSIONS: Esomeprazole 40 mg administered via an intravenous injection, intravenous infusion or orally administered for 1 week, followed by 3 weeks of oral dosing, is well tolerated and provides effective healing of erosive esophagitis. 相似文献

OBJECTIVE: In patients with gastroesophageal reflux disease (GERD), esomeprazole, the S-isomer of omeprazole, has demonstrated pharmacological and clinical benefits beyond those seen with the racemic parent compound. This study was designed to further evaluate the efficacy and tolerability of esomeprazole relative to that of omeprazole in healing erosive esophagitis and resolving accompanying symptoms of GERD. METHODS: Esomeprazole 40 mg was compared with omeprazole 20 mg once daily in 2425 patients with erosive esophagitis (Helicobacter pylori negative by serology) in an 8-wk, multicenter, randomized, double-blind, parallel-group study conducted in 163 centers throughout the US. The primary efficacy endpoint was the proportion of patients with healed esophagitis at wk 8. Secondary endpoints were the proportion of patients healed at wk 4, resolution of heartburn at wk 4, time to first resolution and sustained resolution of heartburn, and proportion of heartburn-free days and nights. Safety and tolerability were also assessed. RESULTS: Significantly more patients were healed with esomeprazole versus omeprazole at wk 8 (93.7% vs 84.2%, p < 0.001; life table estimates, intention-to-treat analysis). Healing rates at wk 4 were 81.7% and 68.7%, respectively. Esomeprazole was superior to omeprazole for all secondary measures and had a similar safety profile. The most common adverse events in both treatment groups were headache, diarrhea, and nausea. CONCLUSIONS: Esomeprazole demonstrates significantly greater efficacy than omeprazole in the treatment of GERD patients with erosive esophagitis. The tolerability and safety of esomeprazole are comparable to that of omeprazole. (Am 相似文献

Two hundred thirty patients with reflux symptoms and endoscopically proven erosive esophagitis were enrolled from 15 U.S. centers into a randomized, double-blind, dose-ranging study comparing placebo with omeprazole, 20 or 40 mg given once daily in the morning. Esophagitis grade 2 was present in 44% of patients, grade 3 in 37% of patients, and grade 4 in 19% of patients. Endpoints, defined as complete relief of heartburn and complete esophageal mucosal healing, were assessed after 4 and 8 weeks of treatment. Both omeprazole doses were significantly superior to placebo in complete endoscopic healing. After 8 weeks of treatment, 73.5% of patients in the 20-mg omeprazole group and 74.7% in the 40-mg omeprazole group, compared with 14.0% in the placebo group, had complete healing of the esophageal mucosa. At the end of the study, complete relief of daytime heartburn was obtained in 79.5% of patients in the 20-mg omeprazole group, 81.6% in the 40-mg omeprazole group, and 37.2% in the placebo group (P less than or equal to 0.05). Complete relief of nighttime heartburn was noted by 79.5% of patients in the 20-mg omeprazole group, 85.1% in the 40-mg omeprazole group, and 34.9% in the placebo group (P less than or equal to 0.05). The median time to complete relief of daytime and nighttime heartburn occurred earlier in the 40-mg group than in the 20-mg group (9 vs. 17 days and 9 vs. 20 days, respectively); however, these differences were not statistically significant. Relief of acid regurgitation and dysphagia also occurred earlier in the 40-mg group. Omeprazole was well tolerated in this group of patients. No unexpected adverse experiences occurred. The results of this study confirm those of six multicenter, international trials in which omeprazole in doses of 20-60 mg provided a degree of esophageal mucosal healing and complete relief of reflux symptoms superior to any other medical treatment. 相似文献
