Azithromycin in a triple therapy for H.pylori eradication in active duodenal ulcer

AIM：To assess and compare the efficacy and safety of two triple regimes:A)metronidazole,amoxicillin and omeprazole,which is still widely used in Russia,andB)azithromycin amoxicillin and omeprazole in healing active duodenal ulcer and H.pylori eradication.METHODS:100 patients with active duodenal ulcer were includid in the open,multicentre,randomized study with comparative groups.Patients were randomly assigned to one of the following one-week triple regimes:A)metronidazole500mg bid,amoxicillin1gbid and omeprazole 20mg bid(OAM,n=50)andB)azithromycin1g od for the first3days(total dose3g).amoxicillin 1g bid and first 3days(total dose3g).amoxicillin 1g bid and omeprazole20mg bid(OAA,n=50).Omeprazole 20mg od was given after the eradication course as a monotherapy for three weeks ,The control endoscopy was performed8 weeks after the entry,H.pyloriinfection was determined in the entry of the study and four weeks after the cessation of treatment by means of histology and CLO-test.RESULTS:97 patients completed the study according to the protocol(1patient of the OAM group did not come to the control endoscopy.2patients of the OAA group stopped the treatment because of mild allergic urticaria).Duodenal ulcers were healed in48patients of the OAM group(96%;CI90.5-100%)and in 46patients of the OAAgroup(92%;CI89.5-94.5%)(p=ns).H.pylori infection was eradicated in 15out of 50patients with OAM(30%;CI17-43%)and in36out of 50patients treated with OAA(72%,CI59-85%)(P&lt;0.001)-IПanalysis.CONCLUSION:The triple therapy with omeprazole,amoxicillin and metronidazole failed to eradicateH.pylori in the majorty of patients,which is an essential argument to withdraw this regimen out of the national recommendations,Macrolide with amoxicillin are preferable to achieve higher eradication rates.Azitromycin(1g od for the first3days)can be considered as a successful component of the triple PPI-based regimen.     

Clinical evaluation of four one-week triple therapy regimens in eradicating Helicobacter pylori infection

AIM: To evaluate clinical efficacy of four one-week triple therapies in eradicating Helicobacter pylori infection. METHODS: In this clinical trial, 132 patients with duodenal ulcer and chronic gastritis were randomly divided into four groups, and received treatment with OAC (omeprazole 20 mg + amoxicillin 1 000 mg + clarithromycin 250 mg), OFC (omeprazole 20 mg + furazolidone 100 mg + clarithromycin 250 mg), OFA (omeprazole 20 mg + furazolidone 100 mg + amoxicillin 1 000 mg) and OMC (omeprazole 20 mg + metronidazole 200 mg + clarithromycin 250 mg), respectively. Each drug was taken twice daily for one week. The (13)C urea breath test was carried out 4-8 weeks after treatment to determine the success of H pylori eradication. RESULTS: A total of 127 patients completed the treatment. The eradication rate for H pylori infection was 90.3%, 90.9%, 70.9% and 65.6%, respectively in OAC, OFC OMC and OFA groups. CONCLUSION: A high eradication rate can be achieved with one-week OAC or OFC triple therapy. Thus, one-week triple therapies with OAC and OFC are recommended for Chinese patients with duodenal ulcers and chronic gastritis.     

Efficacy of omeprazole and amoxicillin with either clarithromycin or metronidazole on eradication of Helicobacter pylori in Chinese peptic ulcer patients

AIM: One-week triple therapy with proton pump inhibitors, clarithromycin and amoxicillin has recently been proposed as the first-line treatment for Helicobacter pylori (H pylori) infection; however, data regarding the effects of this regimen in China are scarce. The aim of this prospective and randomized study was to compare the efficacy of clarithromycin and metronidazole when they were combined with omeprazole and amoxicillin on eradication of H pylori and ulcer healing in Chinese peptic ulcer patients. METHODS: A total of 103 subjects with Hpylori-positive peptic ulcer were randomly divided into two groups, and accepted triple therapy with omeprazole 20 mg, amoxicillin 1 000 mg and either clarithromycin 500 mg (OAC group, n = 58) or metronidazole 400 mg (0AM group, n - 45). All drugs were given twice daily for 7 d. Patients with active peptic ulcer were treated with omeprazole 20 mg daily for 2-4 wk after anti-H pylori therapy. Six to eight weeks after omeprazole therapy, all patients underwent endoscopies and four biopsies (two from the antrum and two others from the corpus of stomach) were taken for rapid urease test and histological analysis (with modified Giemsa staining) to examine H pylori. Successful eradication was defined as negative results from both examination methods. RESULTS: One hundred patients completed the entire course of therapy and returned for follow-up. The eradication rate of H pylori for the per-protocol analysis was 89.3% (50/56) in OAC group and 84.1% (37/44) in 0AM group. Based on the intention-to-treat analysis, the eradication rate of H pylori was 86.2% (50/58) in OAC group and 82.2% (37/45) in 0AM group. There were no significant differences in eradication rates between the two groups on either analysis. The active ulcer-healing rate was 96.7% (29/30) in OAC group and 100% (21/21) in 0AM group (per-protocol analysis, P>0.05). Six patients in OAC group (10.3%) and five in OAM group (11.1%) reported adverse events (P>0.05). CONCLUSION: One-week triple therapy with omeprazole and amoxicillin in combination with either clarithromycin or metronidazole is effective for the eradication of H pylori. The therapeutic regimen comprising metronidazole with low cost, good compliance and mild adverse events may offer a good choice for the treatment of peptic ulcers associated with H pylori infection in China.     

Azithromycin in a triple therapy for H. pylori eradication in active duodenal ulcer

AIM: To assess and compare the efficacy and safety of twotriple regimes: A) metronidazole, amoxicillin and omeprazole,which is still widely used in Russia, and B) azithromycin,amoxicillin and omeprazole in healing active duodenal ulcerand H.pylori eradication. METHODS: 100 patients with active duodenal ulcer wereincluded in the open, multicentre, randomized study withcomparative groups. Patients were randomly assigned toone of the following one-week triple regimes: A)metronidazole 500 mg bid, amoxicillin 1 g bid and omeprazole20 mg bid (OAM, n＝50) and B) azithromycin 1 g od for thefirst 3 days (total dose 3 g), amoxicillin 1 g bid andomeprazole 20 mg bid (OAA, n＝50). Omeprazole 20 mg odwas given after the eradication course as a monotherapyfor three weeks. The control endoscopy was performed 8weeks after the entry. H. pylori infection was determined inthe entry of the study and four weeks after the cessation oftreatment by means of histology and CLO-test.RESULTS: 97 patients completed the study according tothe protocol (1 patient of the OAM group did not come tothe control endoscopy, 2 patients of the OAA group stoppedthe treatment because of mild allergic urticaria). Duodenalulcers were healed in 48 patients of the OAM group (96 %;CI 90.5-100 %) and in 46 patients of the OAA group (92 %;CI 89.5-94.5 %) (p＝ns). H. pylori infection was eradicatedin 15 out of 50 patients with OAM (30 %; CI 17-43 %) andin 36 out of 50 patients treated with OAA (72 %; CI 59-85 %)(P＜0.001)-ITT analysis.CONCLUSION: The triple therapy with omeprazole,amoxicillin and metronidazole failed to eradicate H. pylori inthe majority of patients, which is an essential argument towithdraw this regimen out of the national recommendations.Macrolide with amoxicillin are preferable to achieve highereradication rates. Azithromycin (1 g od for the first 3 days)can be considered as a successful component of the triplePPI-based regimen.     

Amoxicillin plus omeprazole versus triple therapy for eradication of Helicobacter pylori in duodenal ulcer disease: a prospective, randomized, and controlled study.

Treatment with amoxicillin and omeprazole resulted in encouraging Helicobacter pylori eradication rates in pilot studies that included medium term follow up. These results were evaluated in a prospective, randomised and controlled study. Forty patients with active duodenal ulcer disease and H pylori colonisation of the gastric mucosa were randomly assigned to receive either omeprazole (20 mg twice daily) and amoxicillin suspension (500 mg four times daily) for two weeks (group I) or bismuth subsalicylate (600 mg three times daily), metronidazole (400 mg three times daily), tetracycline (500 mg three times daily), and ranitidine (300 mg in the evening) for two weeks (group II). Study medication was followed in both groups by a four week treatment course with 300 mg ranitidine up to the final examination. One patient from each group was lost to follow up. H pylori was eradicated in 78.9% of group I and 84.2% of group II (p = 1.00). All ulcers in patients on omeprazole plus amoxicillin healed but in the triple treatment group four patients had residual peptic lesions after six weeks (ulcer healing rate: 78.9%, p = 0.11). Complete pain relief occurred after a median duration of 1 day in group I and of 6 days in group II (p = 0.03). There were no major complications in either group but minor side effects were more frequently recorded in patients on triple therapy (63.2% v 15.8%, p < 0.01). In conclusion, two weeks of treatment with omeprazole plus amoxicillin is as good as triple therapy plus ranitidine in eradicating H pylori but seems better with regard to safety, pain relief, and ulcer healing. Thus, amoxicillin plus omeprazole should be recommended as the treatment of choice in eradicating H pylori in patients with duodenal ulcer disease.     

Influence of Helicobacter pylori eradication therapy on the occurrence of gastrointestinal events in patients treated with conventional nonsteroidal antiinflammatory drugs combined with omeprazole

OBJECTIVE: To evaluate the effect of eradication treatment of Helicobacter pylori and the influence of H. pylori status on the incidence of gastrointestinal (GI) events in rheumatic patients receiving longterm conventional nonsteroidal antiinflammatory drug (NSAID) therapy combined with omeprazole. METHODS: Patients (n = 919) requiring longterm NSAID therapy entered this multicenter, open label, parallel group study. H. pylori positive patients were randomized to receive either eradication therapy (omeprazole 20 mg bid, amoxicillin 1 g bid, and clarithromycin 500 mg bid for 7 days) or no therapy. Both these groups and the H. pylori negative patients were given omeprazole, 20 mg once daily, along with NSAID for the study duration (5-8 weeks). Treatment failure (primary outcome variable) was defined as the occurrence of severe GI event (symptomatic ulcer, bleeding, perforation) or dyspepsia leading to discontinuation of NSAID therapy, unscheduled consultation, or upper GI tract endoscopy. RESULTS: Treatment failure was recorded in 9/294 (3.06%) infected patients receiving eradication therapy, 8/219 (3.65%) infected patients receiving omeprazole alone, and 5/391 (1.28%) H. pylori negative patients (p > 0.05). H. pylori eradication did not appear to influence the incidence and severity of dyspeptic symptoms in infected patients. CONCLUSION: Our results do not support the use of H. pylori eradication therapy in rheumatic patients receiving conventional NSAID along with omeprazole.
