Esomeprazole in treating duodenal ulcer in various modes of anti-Helicobacter therapy

AIM: To assess efficiency of esomeprazole in the treatment of duodenal ulcer (DU) associated with H. pylori in various eradication regimens. MATERIAL AND METHODS: 80 patients with duodenal ulcer at least 0.5 cm in diameter were randomized into three groups. 23 patients of group 1, 28 patients of group 2 received esomeprazole for 7 days in a dose 20 mg twice a day, in a single morning dose 40 mg, respectively. 29 patients of group 3 received omeprazole 20 mg twice a day for 7 days and further 3 weeks 20 mg twice a day. All the patients were also given amoxicillin 1000 mg twice a day and clarithromycin 500 mg twice a day for a week. RESULTS: An antisecretory effect of esomeprazole as shown by 24-h monitoring of gastric secretion was longer and more stable than that of omeprazole: a latent period averaged 1.5 +/- 0.6 h in a pharmacological test with 20 mg esomeprazole, 1.2 +/- 0.4 h in intake of 40 mg esomeprazole and 2.1 +/- 0.3 h in intake of 20 mg omeprazole. Overall duration of the antisecretory effect averaged 16.8 +/- 1.9, 20.3 +/- 1.7 and 12.5 +/- 1.9 h, respectively. The time of intragastric pH > 4 was 13.1 +/- 1.6, 17.2 +/- 1.6 and 9.8 +/- 1.5 hours, respectively. Eradication of H. pylori in group 1, 2 and 3 was 91.3, 89.3 and 89.6%, respectively. Complete epithelization of ulcer occurred in 95.6, 92.8 and 93.1% cases, respectively. In 77 patients who finished the treatment according to the protocol the treatment resulted in eradication in 95.6, 92.5 and 92.8%, respectively; in epithelization--in 100, 96.3 and 96.4% patients of groups 1, 2 and 3, respectively. Side effects were mild or moderate but not causing changes of the regimen or treatment discontinuation. CONCLUSION: Esomeprazole in three-component treatment was highly effective in eradication of H. pylori and epithelisation of duodenal ulcer defects in various regimens of administration. Esomeprazole in combination with amoxicillin and clarithromycin reduces the time of treatment of DU associated with H. pylori to 1 week without further monotherapy with antisecretory drugs.     

Evaluation of the efficacy and the cost-effectiveness of proton pump inhibitor-based dual and triple therapy regimens for H. pylori eradication in peptic ulcer disease

To evaluate the efficacy and the cost-effectiveness of H. pylori eradication for the treatment of peptic ulcer disease, a randomized controlled trial to compare the efficacy of proton pump inhibitor-based dual and triple regimens was conducted. A decision analysis was also performed to assess H. pylori eradication compared to the conventional maintenance strategy. Two hundred and thirty-four peptic ulcer patients suffering from H. pylori infection were randomly treated with either omeprazole 20 mg bid + amoxicillin 500 mg qid + clarithromycin 400 mg bid (OAC) or with omeprazole 20 mg bid + clarithromycin 400 mg bid (OC) for 14 days. The eradication rate with OAC was 87.6% (92/105) (95% Confidence Interval (CI): 81-94%), which was significantly higher than that with OC (61.9% (60/97) (95% CI: 52-72%)) (p < 0.001, chi 2 test). Both regimens were safe and well tolerated. H. pylori eradication was more effective and less costly than conventional strategy in a long term perspective. OAC was more cost-effective than OC. In conclusion, H. pylori eradication is a cost-effective alternative to conventional treatment. We recommend 2 weeks triple regimen with omeprazole 20 mg bid + amoxicillin 500 mg qid + clarithromycin 400 mg bid (OAC) as a first-line treatment in all patients with peptic ulcers associated with H. pylori infection.     

Results of an open multicenter study of the efficiency of one-week anti-helicobacter therapy using omeprazole, clarithromycin, and amoxicillin in patients with duodenal peptic ulcer

AIM: To study the efficiency of one-week antihelicobacter therapy using omeprazole, clarithromycin, and amoxycillin in patients with duodenal peptic ulcer during its recurrence. MATERIALS AND METHODS: 105 patients with recurrent peptic ulcer and a not less than 0.5-cm ulcer in the duodenal bulb was given triple therapy: omeprazole, 20 mg twice daily, amoxycillin, 1000 mg twice daily, and clarithromycin, 500 mg twice daily for 7 days. Then the patients were allowed to take antacids if they were required to abolish the symptoms of recurrent peptic ulcer. H. pylori was detected in the mucosal biopsy specimens taken from the anthral part and body of the stomach at gastroduodenascopy, by using the rapid urease test and histology. Gastroduodenoscopy was performed before and 4-6 weeks after the triple therapy. RESULTS: The major symptoms of recurrent peptic ulcer were eliminated in 90% of the patients by the end of a course of therapy, i.e. on its day 7. By the control time, the rate of ulcer cicatrization was 99.05% (104/105). The coincidence of results of the two tests has indicated that H. pylori eradication was 81.9% (86/105) 4-6 weeks after termination of treatment. Adverse reactions during therapy were observed in 20% of the patients; however, treatment had to be discontinued only in 2.9% of the patients. CONCLUSION: One-week triple therapy using omeprazole, clarithromycin, and amoxycillin in highly effective in treating duodenal peptic ulcer during its recurrence.     

Comparison of H2-receptor antagonist- and proton-pump inhibitor-based triple regimens for the eradication of Helicobacter pylori in Chinese patients with gastritis or peptic ulcer

This study compared the efficacy of an H2-receptor antagonist (H2RA)- and a proton-pump inhibitor (PPI)-based triple regimen for the eradication of Helicobacter pylori infection. Chinese patients with H. pylori-associated gastritis or peptic ulcer were randomized to receive the H2RA-based triple regimen (20 mg famotidine, 1.0 g amoxicillin and 0.4 g metronidazole) or the PPI-based triple regimen (20 mg omeprazole, 1.0 g amoxicillin and 0.4 g metronidazole) both twice daily for 1 or 2 weeks. Successful eradication of H. pylori was determined by the 13C-urea breath test and gastric mucosa histology at least 4 weeks after completion of antibiotic therapy. Eradication rates were 56.0% and 76.9% for the 1-week H2RA- and PPI-based triple regimens, respectively, and 81.6% and 82.1% for the 2-week regimens, respectively. The H. pylori eradication rate for the 2-week H2RA regimen was significantly higher than that for the 1-week regimen, but there were no significant differences between the 1- and 2-week PPI regimens. The two regimens proved equally effective in eradicating H. pylori infection.     

Lansoprazole-based triple therapy versus ranitidine bismuth citrate-based dual therapy in the eradication of Helicobacter pylori in patients with duodenal ulcer: a multicenter, randomized, double-dummy study

BACKGROUND: The optimal treatment regimen for eradication of Helicobacter pylori in patients with duodenal ulcer has yet to be determined. Based on a search of MEDLINE, no studies have been performed comparing a proton pump inhibitor-based triple therapy regimen with a ranitidine bismuth citrate (RBC)-based dual therapy regimen, both containing clarithromycin. OBJECTIVE: This study was undertaken to compare the efficacy of lansoprazole (LAN)-based triple therapy with that of RBC-based dual therapy in H pylori-infected patients with duodenal ulcer. METHODS: Patients were randomized to receive either 1 week of triple therapy with LAN 30 mg BID, clarithromycin 500 mg BID, and tinidazole 500 mg BID, followed by 3 weeks of LAN 30 mg BID, or 2 weeks of dual therapy with RBC 400 mg BID plus clarithromycin 500 mg BID, followed by 2 weeks of RBC 400 mg BID. Eradication of H pylori was defined as negative results on both the urease quick test and histologic examination > or =4 weeks after the end of treatment. Duodenal healing and recurrence rates were assessed endoscopically at 8 weeks and 6 months. A per-protocol (PP) analysis was conducted for each efficacy end point. Also conducted were an intent-to-treat (ITT) analysis in which patients with missing data were considered failures, and an observed analysis (OBS), which included patients with an evaluable result after treatment, regardless of compliance. RESULTS: One hundred eighty-five patients (126 men, 59 women; age range, 18-76 years; mean age, 43 years) were enrolled and randomized to treatment. In the LAN and RBC groups, respectively, H. pylori eradication rates were 92.6%, 93.1%, and 72.8% versus 78.6%, 77.9%, and 64.5% in the PP (P = 0.02), OBS (P = 0.01), and ITT analyses. The corresponding duodenal ulcer healing rates were 98.6%, 98.7%, and 83.7% versus 90.8%, 91.5%, and 81.7%; these differences were not statistically significant. Side effects were mild, occurring in 20.7% of LAN patients and 17.2% of RBC patients. Ulcer recurred in 2 RBC patients. No difference was observed between treatments in terms of the occurrence of gastritis or improvement of symptoms. CONCLUSION: Based on the results of the PP and OBS analyses, LAN-based triple therapy was superior to RBC-based dual therapy for the eradication of H. pylori in patients with duodenal ulcer.

Cure of refractory duodenal ulcer and infection caused by Helicobacter pylori by high doses of omeprazole and amoxicillin in a homozygous CYP2C19 extensive metabolizer patient

A 53-year old female patient with duodenal ulcer and Helicobacter pylori infection was treated three times with a proton pump inhibitor-based triple therapy, such as lansoprazole-clarithromycin-amoxicillin (INN, amoxicilline) and lansoprazole-minocycline-cefaclor. However, the H pylori infection was not cured. A culture test revealed that her infection was a clarithromycin-resistant but amoxicillin-sensitive strain of H pylori. Moreover, a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis revealed that she was a homozygous extensive metabolizer of cytochrome P450 (CYP) 2C19 (wt/wt). The usual dose of the proton pump inhibitor was therefore assumed to be insufficient for her and then she was treated with a high dose of omeprazole (120 mg/day) and amoxicillin (2,250 mg/day) for 2 weeks. The H pylori infection and the ulcer lesion were then cured. One of the factors associated with success or failure of cure of H pylori infection by the proton pump inhibitor-based triple therapy appeared to be CYP2C19 genotype status. Dual treatment with a sufficient dose of a proton pump inhibitor plus amoxicillin could cure H pylori infection even after the failure to cure H pylori infection by a usual proton pump inhibitor-based triple therapy in patients with the wt/wt homozygous extensive metabolizer genotype of CYP2C19.     

Proton pump inhibitor-amoxicillin-clarithromycin versus proton pump inhibitor-amoxicillin-metronidazole as first-line Helicobacter pylori eradication therapy

The aim of this study was to compare the efficacy and tolerability of the first-line Helicobacter pylori (H. pylori) eradication regimen composed of proton pump inhibitor, clarithromycin, and amoxicillin, with those of a regimen composed of proton pump inhibitor, metronidazole, and amoxicillin. Data of patients, who were administered the first-line H. pylori eradication regimen at Tokyo Medical Center between 2008 and 2011, were reviewed. All patients had H. pylori gastritis without peptic ulcer disease. The 7-day triple regimen composed of lansoprazole, clarithromycin, and amoxicillin was administered to 55 patients, and that composed of omeprazole, metronidazole, and amoxicillin was administered to 55 patients. Intention-to-treat and per-protocol eradication rates were 74.5 and 80.4%, respectively, for the regimen of lansoprazole, clarithromycin, and amoxicillin, whereas the corresponding rates were 96.4 and 100%, respectively, for the regimen of omeprazole, metronidazole, and amoxicillin. In conclusion, first-line H. pylori eradication therapy composed of omeprazole, metronidazole, and amoxicillin was significantly more effective than that composed of lansoprazole, clarithromycin, and amoxicillin, without differences in tolerability.
