Efficacy of moxifloxacin-based sequential therapy for first-line eradication of Helicobacter pylori infection in gastrointestinal disease

AIM:To evaluate the efficacy of 14-d moxifloxacinbased sequential therapy as first-line eradication treatment of Helicobacter pylori(H.pylori) infection.METHODS:From December 2013 to August 2014, 161 patients with confirmed H.pylori infection randomly received 14 d of moxifloxacin-based sequential group(MOX-ST group, n = 80) or clarithromycin-based sequential group(CLA-ST group, n = 81) therapy.H.pylori infection was defined on the basis of at least one of the following three tests:a positive 13C-urea breath test; histologic evidence of H.pylori by modified Giemsa staining; or a positive rapid urease test(CLOtest; Delta West, Bentley, Australia) by gastric mucosal biopsy.Successful eradication therapy for H.pylori infection was defined as a negative 13C-urea breath test four weeks after the end of eradication treatment.Compliance was defined as good when drug intake was at least 85%.H.pylori eradication rates, patient compliance with drug treatment, adverse event rates, and factors influencing the efficacy of eradication therapy were evaluated.RESULTS:The eradication rates by intention-to-treat analysis were 91.3%(73/80;95%CI:86.2%-95.4%)in the MOX-ST group and 71.6%(58/81;95%CI:65.8%-77.4%)in the CLA-ST group(P=0.014).The eradication rates by per-protocol analysis were 93.6%(73/78;95%CI:89.1%-98.1%)in the MOX-ST group and 75.3%(58/77;95%CI:69.4%-81.8%)in the CLAST group(P=0.022).Compliance was 100%in both groups.The adverse event rates were 12.8%(10/78)and 24.6%(19/77)in the MOX-ST and CLA-ST group,respectively(P=0.038).Most of the adverse events were mild-to-moderate in intensity;there was none serious enough to cause discontinuation of treatmentin either group.In multivariate analysis,advanced age(≥60 years)was a significant independent factor related to the eradication failure in the CLA-ST group(adjusted OR=2.13,95%CI:1.97-2.29,P=0.004),whereas there was no significance in the MOX-ST group.CONCLUSION:The 14-d moxifloxacin-based sequential therapy is effective.Moreover,it shows excellent patient compliance and safety compared to the 14-d clarithromycin-based sequential therapy.     

Efficacy of 7 day lansoprazole-based triple therapy for Helicobacter pylori infection in elderly patients

BACKGROUND: The prevalence of Helicobacter pylori increases with age. However, data regarding the effects of anti-H. pylori treatments in the elderly are very scarce. METHODS: To evaluate the effect of three lansoprazole-based, 7 day, triple-therapy regimens on H. pylori eradication rates, symptomatology, chronic gastritis activity and serological markers of H. pylori infection in elderly subjects, we studied 150 symptomatic patients over 60 years of age with H. pylori-positive duodenal ulcer (DU, n = 34), gastric ulcer (GU, n= 19) or chronic gastritis (CG, n = 97). Patients were consecutively treated with one of the following regimens: (A) lansoprazole (LNS) 30 mg b.i.d. + clarithromycin (CLR) 250 mg b.i.d. + metronidazole (MTR) 250 mg q.i.d.; (B) LNS 30mg b.i.d. + amoxycillin (AMOX) 1 g b.i.d. + MTR 250 mg q.i.d.; and (C) LNS 30 mg b.i.d. + CLR 250 mg b.i.d. + AMOX 1 g b.i.d. RESULTS: Two months after therapy, the eradication rates of the three treatments, expressed using both intention-to-treat and per-protocol analyses were, respectively; group A, 86 and 91.5%; group B, 80 and 87%; group C, 82 and 89.1%. After therapy, a significant reduction in epigastric pain (P<0.001), heartburn (P=0.02), dyspepsia (P<0.001) and vomiting (P< 0.005) was observed independently of the success of H. pylori eradication. A significantly higher percentage of asymptomatic patients were in the GU-DU group than in CG group (87.7 vs 70.0%, P= 0.032). After therapy, 33 subjects still suffered from symptoms. Persistence of symptoms was significantly associated with an endoscopic diagnosis of oesophagitis and not with H. pylori infection. Patients cured of H. pylori infection showed a significant decrease in the histological activity of both antral and body gastritis (P< 0.0001), a significant drop in immunoglobulin (Ig) G anti-H. pylori antibodies (P< 0.0001) and pepsinogen (PG) C (P<0.0001) and an increase in the PGA/PGC ratio (P<0.0001). CONCLUSIONS: The 7 day, lansoprazole-based triple therapy was well tolerated and highly effective in the cure of H. pylori infection, the reduction of symptoms, chronic gastritis activity and serum levels of IgG anti-H. pylori antibodies and PGC. Persistence of symptoms after therapy was significantly higher in CG than GU and DU patients and was significantly associated with oesophagitis.     

Efficacy of moxifloxacin-based sequential and hybrid therapy for first-line Helicobacter pylori eradication

AIM: To evaluate the efficacy of moxifloxacin-based sequential therapy(MBST) versus hybrid therapy as a first-line treatment for Helicobacter pylori(H. pylori) infection.METHODS: From August 2014 to January 2015, 284 patients with confirmed H. pylori infection were randomized to receive a 14-d course of MBST(MBST group, n = 140) or hybrid(Hybrid group, n = 144) therapy. The MBST group received 20 mg rabeprazole and 1 g amoxicillin twice daily for 7 d, followed by 20 mg rabeprazole and 500 mg metronidazole twice daily, and 400 mg moxifloxacin once daily for 7 d. The Hybrid group received 20 mg rabeprazole and 1 g amoxicillin twice daily for 14 d. In addition, the Hybrid group received 500 mg metronidazole and 500 mg clarithromycin twice daily for the final 7 d. Successful eradication of H. pylori infection was defined as a negative 13C-urea breath test 4 wk after the end of treatment. Patient compliance was defined as "good" if drug intake was at least 85%. H. pylori eradication rates, patient compliance with treatment, and adverse event rates were evaluated.RESULTS: The eradication rates in the intention-totreat(ITT) analysis were 91.4%(128/140; 95%CI: 90.2%-92.9%) in the MBST group and 79.2%(114/144; 95%CI: 77.3%-80.7%) in the Hybrid group(P = 0.013). The eradication rates in the perprotocol(PP) analysis were 94.1%(128/136; 95%CI: 92.9%-95.6%) in the MBST group and 82.6%(114/138; 95%CI: 80.6%-84.1%) in the Hybrid group(P = 0.003). The H. pylori eradication rate in the MBST group was significantly higher than that of the Hybrid group for both the ITT(P = 0.013) and the PP analyses(P = 0.003). Both groups exhibited full compliance with treatment(MBST/Hybrid group: 100%/100%). The rate of adverse events was 11.8%(16/136) and 19.6%(27/138) in the MBST and Hybrid group, respectively(P = 0.019). The majority of adverse events were mild-to-moderate in intensity; none were severe enough to cause discontinuation of treatment in either group.CONCLUSION: MBST was more effective and led to fewer adverse events than hybrid therapy as a first-line treatment for H. pylori infection.     

Helicobacter pylori infection in elderly patients

PURPOSES: Helicobacter pylori (H. pylori) infection is a chronic gastric Gram-negative infection that increases with age. Acquired in childhood, H. pylori infection may induce a whole cascade of events leading to gastric pathologies such as peptic ulcer diseases, gastric precancerous lesions, and gastric lymphomas (MALT). The characteristics of the diagnosis and the treatment of this infection in geriatrics are thus particularly important to take into account. MAIN POINTS: 1) The incidence of gastric and duodenal ulcers and their bleeding complications is increasing in old-aged populations. Clinical signs such as anorexia and malnutrition are proven to be excellent indications for endoscopic explorations in the elderly. NSAID-use and H. pylori infection were shown to be independent and unrelated risk factors for peptic ulcer and gastroduodenal bleeding in elderly subjects; 2) H. pylori infection diagnosis is difficult to realize in the very old population, and the urea breath test is the test which obtain the best performances in this population. PERSPECTIVES: Recent work showed the part played by H. pylori chronic infection in gastric aging and in appetite regulation in the elderly. Research tasks should be continued in this field in order to better understand the part played by this chronic infection in gastric aging and in other pathologies (i.e. neurological or cardiovascular diseases) in this population.     

幽门螺杆菌的治疗有望改善——序贯疗法

幽门螺杆菌（H.pylori）的成功根除需要联合使用几种细菌敏感的抗生素。H.pylori生存于酸性环境中,因此对于酸敏感的抗生素,欲使其发挥最大效用并克服表型耐药的发生,就必需结合抑酸治疗。H.pylori根除失败多由表型耐药或获得性耐药所致。根据结核的治疗经验,除耐药性因素外,根除失败主要与疗程和（或）剂量不足有关。由质子泵抑制剂（PPI）和两种抗生素组成的传统三联疗法以及由铋剂、甲硝唑和四环素（BMT）组成的三联疗法是最常用的方案。
