Furazolidone, amoxicillin, bismuth and rabeprazole quadruple rescue therapy for the eradication of Helicobacterpylori

AIM： To compare the efficacy and side effect profiles of three furazolidone and amoxicillin-based quadruple rescue therapies for the eradication of Helicobacter pylori （H pylonS. METHODS： Patients who failed in the Hpylori eradication therapy for at least one course were randomly allocated into three groups. Group A received rebaprazole 10 mg＋ amoxicillin 1 g ＋ furazolidone 100 mg, and bismuth subcitrate 220 mg, twice daily for 1 wk; group B received the same regimen of group A but for 2 wk; and group C received the same regimen of group B, but furazolidone was replaced by furazolidone 100 mg three times daily. To record the side effect profiles at the end of the treatment, Hpylori eradication was assessed with 13C-urea breath test 4 wk after therapy. RESULTS： Sixty patients were enrolled including 28 males, and 20 patients in each group. The average age of the patients was 49.2 years, ranging from 18 to 84 years. H pylori eradication rates with per-protocol analysis were 82%, 89% and 90% in the three groups, respectively. Side effects were found in 11 patients, including mild dizziness, nausea, diarrhea and increased bowel movement. None of the 11 patients needed treatment for their side effects. CONCLUSION： One- or two-week furazolidone and amoxicillin-based quadruple rescue therapy with a low dose furazolidone （100 mg bid） for the eradication of Hpylori is effective. Extending the antibiotic course to 14 d could improve the eradication rates.     

Eradication of H pylori infection in a rural population： One-day quadruple therapy versus 7-day triple therapy

AIM: To compare the one-day quadruple therapy with a standard 7-d triple therapy for H pylori eradication in a rural population of China. METHODS: A total of 396 patients with 13C-urea breath test positive for H pylori were assigned into two groups: 239 patients received one-day quadruple therapy (amox icillin 2000 mg qid; metronidazole 500 mg qid; bismuth citrate 900 mg qid and lansoprazole 60 mg once daily) and 157 patients received 7-d standard triple therapy (amoxicillin 1000 mg bid; clarithromycin 500 mg bid and lansoprazole 30 mg bid). All the patients underwent a 13C-UBT to assess the eradication of H pylori infection six weeks after treatment. RESULTS: Two hundred and twenty-nine patients completed the one-day therapy (95.8%) and 148 patients completed the 7-d therapy (94.2%). The one day therapy eradicated H pylori infection in 64 patients (27.95%). In contrast, 103 patients (69.59%) were H pylori negative after the 7-d therapy (P < 0.01). CONCLUSION: This pilot study suggests there is no beneficial effect of the one-day therapy in treatment of H pylori infection compared with the 7-d standard therapy.     

幽门螺杆菌根除治疗失败后的补救治疗

幽门螺杆菌（H.pylori)对抗生素的耐药率上升是导致根除治疗失败率上升的主要原因，对经标准方案根除H.pylori失败的患者有必要进行补救治疗。目的：评估铋剂、质子泵抑制剂（PPI）联用呋喃唑酮和四环素组成的7天四联方案用于根除H.pylori治疗失败后补救治疗的疗效，以及H.pylori耐药对疗效的影响。方法：予35例经含克拉霉素根除H.pylori方案治疗、H.pylori仍为阳性的患者以为期7天的四联治疗：枸橼酸铋钾220mg bid 奥美拉唑20mg bid 呋喃唑酮100mg bid 四环素750mg bid。治疗前取胃窦黏膜活检标本进行快速尿素酶试验、组织学检查和培养检测H.pylori。用琼脂扩散法测定克拉霉素、呋喃唑酮和四环素的最低抑菌浓度（MIC）。治疗结束后至少4周，采用^13C-尿素呼气试验进行H.pylori感染状态评估。结果：33例患者完成治疗和随访，2例失访。根据意图治疗（ITT）和试验方案（PP）分析，该补救方案的H.pylori根除率分别为68．6％（24／35）和72．7％（24／33）。10例（28．6％）患者发生轻度副反应（9例发生恶心、中上腹不适，1例发生皮疹）。35例中有27例H.pylori培养成功，克拉霉素的耐药率为51．8％（14／27），呋喃唑酮为3．7％（1／27），四环素为7．4％（2／27）。各药物耐药菌株和敏感菌株的H.pylori根除率无显著差异。结论：铋剂、PPI联用呋喃唑酮和四环素组成的7天联方案作为根除H.pylori治疗失败后的补救治疗可获得较高的H.pylori根除率。     

Clinical outcome and influencing factors of a new short-term quadruple therapy for Helicobacter pylori eradication: a randomized controlled trial (MACLOR study).

BACKGROUND: Short-term therapies for eradicating Helicobacter pylori in selected patients might offer advantages in terms of costs, compliance, and adverse effects in contrast to standard 1-week triple therapy. METHODS: To determine eradication success and influencing factors in a new short-term quadruple therapy, a total of 243 patients positive for H pylori were randomly assigned to 1 of 3 regimens according to age, smoking status, and diagnosis: a 5-day treatment with 3 antibiotics (amoxicillin, 1 g twice daily [bid]; clarithromycin, 250 mg bid; and metronidazole, 400 mg bid) and lansoprazole (30 mg bid [L5; reference treatment]) or ranitidine hydrochloride (300 mg bid [R5]), or the same 3-day antibiotic-lansoprazole combination (L3) with a 2-day pretreatment with lansoprazole. RESULTS: A total of 234 patients completed the study. On an intention-to-treat basis, overall eradication of H pylori was confirmed in 86.4%: 89.2% in the L5 group vs 81.2% in the L3 group vs 88.8% in the R5 group; differences were not significant. Multiple logistic regression analysis showed that younger age (<55 years; P =.03), history of peptic ulcer disease (P =.04), smoking (P =.03), metronidazole resistance (P =.003), low ranitidine trough serum concentrations (P =.005), cytotoxin-associated gene A-negative strains in peptic ulcer disease (P =.04), and outer inflammatory protein A-positive strains (P =.02) were associated with eradication failure. CONCLUSIONS: This new quadruple H pylori eradication regimen is efficacious, safe, well tolerated, and cost saving, and may be a treatment option for patients older than 55 years with no history of peptic ulcer disease. Furthermore, strains that are sensitive to all antibiotics, cytotoxin-associated gene A-positive, and outer inflammatory protein A-negative could be suitable for short-term quadruple therapy. Patients with an unfavorable combination of characteristics should be treated for a minimum of 7 days.

背景：对感染幽门螺杆菌（H.pylori）的消化性溃疡患者成功根除且H.ylori后,是否应继续行抑酸治疗,目前尚存在争议。目的：探讨合并H.pylori感染的十二指肠溃疡（DU）患者根除H.pylori后抑酸维持治疗的疗效。方法：112例合并H.pylori感染的DU患者随机分为A组和B组,A组给予10d四联疗法：兰索拉唑30mg＋阿莫西林1g＋克拉霉素0．5gbid＋枸橼酸铋钾110mg qid,疗程10d。B组：在A组方案的基础上,疗程结束后再予兰索拉唑30mg,1次／d,维持4周。治疗结束4周后复查胃镜,评估H.pylori根除疗效、溃疡愈合率和腹痛缓解率。结果：109例患者完成方案。A、B两组按意向治疗（ITT）和按方案（PP）分析的H.pylori根除率（ITT：85．7％对87．5％;PP：88．9％对89．1％）和溃疡愈合率（ITT：87．5％对94．6％;PP：90．7％对96．4％）以及腹痛缓解率（95．6％对95．7％）相比差异均无统计学意义（P〉0．05）。结论：以10d四联疗法根除H.pylori后,可使多数DU患者的溃疡愈合,无需进一步行维持抑酸治疗。     

Levofloxacin-azithromycin combined triple therapy for Helicobacter pylori eradication]

BACKGROUND/AIMS: Antibiotic resistance and poor compliance are the main causes of Helicobacter pylori (H. pylori) eradication failure. This study evaluated the eradication rate, tolerability, and compliance of levofloxacin- azithromycin combined triple therapy for H. pylori eradication. METHODS: 1) First-line eradication: A total of 78 H. pylori-positive patients were enrolled. Seventeen military men in Armed Forces Capital Hospital were treated with 7 days of levofloxacin-azithromycin combined triple therapy (omeprazole 20 mg bid, levofloxacin 500 mg od, and azithromycin 500 mg od), and 61 patients in Kangbuk Samsung Hospital were treated with standard PPI-based triple therapy (omeprazole 20 mg bid, amoxicillin 1.0 g bid, and clarithromycin 500 mg bid) for 7 days. 2) Second-line eradication: A consecutive series of 59 patients who failed H. pylori eradication with standard PPI-based triple therapy in Kangbuk Samsung Hospital were randomized to two groups. Thirty patients were retreated with 7 days of bismuth-based quadruple therapy (omeprazole 20 mg bid, bismuth 120 mg qid, metronidazole 500 mg tid, and tetracycline 500 mg qid), and remaining 29 patients were retreated with levofloxacin-azithromycin combined triple therapy. Patient's compliance and tolerability were evaluated at the end of treatment. The status of H. pylori infection was assessed 8 weeks later then. The successful eradication of H. pylori was defined as negative results from histology and CLO test, or 13C-urea breath test. RESULTS: First-line eradication rate of levofloxacin-azithromycin triple therapy was lower than that of standard PPI-based triple therapy, but there was no statistically significant difference (70.6% vs. 80.3%, p=0.390). Second-line eradication rate of levofloxacin-azithromycin combined triple therapy was significantly lower than that of bismuth-based quadruple therapy (ITT/PP 65.5%/73.1% vs. 90%/90%, p<0.0001). The compliances of all patients were more than 85%. Two of patients with levofloxacin-azithromycin combined triple therapy complained self-limiting side effects (mild dizziness; mild insomnia with general weakness). CONCLUSIONS: Levofloxacin-azithromycin combined triple therapy should not be recommended as the first-line or second-line H. pylori eradication regimen in Korea.     

Effectiveness of triple therapy and quadruple therapy for Helicobacter pylori eradication]

BACKGROUND/AIMS: Quadruple therapy can be considered as a first-line therapy in areas where the resistance rate to clarithromycin is high. Comparison study of triple therapy and quadruple therapy for Helicobacter pylori (H. pylori) eradication is still lacking in Korea despite the increasing prevalence of antibiotic resistance. This study was conducted to compare the efficacy of triple and quadruple therapy as a first-line treatment in H. pylori infected patients with peptic ulcer. METHODS: Consecutive 149 cases of peptic ulcer disease associated with H. pylori infection were randomized either to proton pump inhibitor (PPI, bid), amoxicillin (1,000 mg, bid), and clarithromycin (500 mg, bid) (PAC group) or to PPI (bid), bismuth subcitrate (300 mg, qid), metronidazole (500 mg, tid), and tetracycline (500 mg, qid) (PBMT group) eradication treatments for 7 days. Outcome of eradication therapy was assessed by 13C-urea breath test performed 4-6 weeks after eradication. RESULTS: Eradication rates in PAC and PBMT group were 78.7% (59/75) and 71.6% (53/74) by intention to treat analysis, respectively (p=0.424). By per protocol analysis, eradication rates of PAC and PBMT group were 85.5% (59/69) and 85.5% (53/62), respectively (p=1.012). Adverse reactions occurred in 5 (6.6%) and 7 (9.5%) patients in PAC and PBMT group, respectively (p=0.346). CONCLUSIONS: One week-quadruple therapy as a first-line treatment for H. pylori infection does not offer any advantage over PPI-based triple therapy in Korean patients.

Effects of killing Helicobacter pyloriquadruple therapy on peptic ulcer： A randomized double-blind clinical trial

AIM: To study the therapeutic efficacy of a Chinese and Western integrated regimen, killing Helicobacter pylori quadruple therapy on H pylori-associated peptic ulcers (PU). METHODS: With prospective and double-blind controlled method, seventy-five active PU patients with H pylori infection were randomized to receive one of the following three regimens: (1) new triple therapy (group A: lansoprazole 30 mg qd, plus clarithromycin 250 mg bid, plus amoxycillin 500 mg tid, each for 10 d); (2) killing Hp quadruple therapy(group B: the three above drugs plus killing H pylori capsule 6 capsules bid for 4 wk) and (3) placebo(group C: gastropine 3 tablets bid for 4 wk). H pylori eradication and ulcer healing quality were evaluated under an endoscope 4 wk after treatment. The patients were followed up for 5 years. RESULTS: Both the healing rate of PU and H pylori eradication rate in group B were significantly higher than those in group C (100% and 96.4% vs20% and 0%, respectively,P<0.005), but there was no significant difference compared to those in group A (88% and 92%, P>0.05). The healing quality of ulcer in group B was superior to that in groups C and A (P<0.05). The recurrence rate of PU in group B (4%) was lower than that in group A (10%) and group C (100%,P<0.01).

目的 对进行过根除幽门螺杆菌(H.pylori)治疗而失败的患者,应用含铋剂、质子泵抑制剂的四联疗法和中医药联合补救治疗并观察根除疗效.方法 120例H.pylori阳性患者随机分成两组,每组60例;对照组应用埃索美拉唑镁肠溶片20 mg,枸橼酸铋钾胶囊(商品名丽珠得乐)0.6g(相当于铋0.22 g),阿莫西林(珠海联邦制药股份有限公司)1000 mg,呋喃唑酮(商品名痢特灵,上海利生制药厂生产)100 mg,2次/d,共7d;而治疗组除应用对照组药物外,同时服用中药14 d,观察上腹痛、反酸、饱胀感、嗳气等症状缓解情况,并在补救治疗结束1个月后复查胃黏膜快速尿素酶试验和组织学染色或查14C-尿素呼气试验,观察其根除率.结果治疗组58例完成治疗,其中53例H.pylori转阴,根除率按意图治疗(ITT)和试验方案(PP)分析分别为88.33％ (53/60)和91.38％(53/58),对照组55例完成治疗,其中48例转阴,根除率按意图治疗(ITT)和试验方案(PP)分析分别为80.00％(48/60)和87.27％(48/55),两组间比较有显著性差异(P＜0.05).治疗后两组症状缓解率分别为94.83％(治疗组)和83.64％(对照组),两组间比较有显著性差异(P＜0.05).结论 对H.pylori根除治疗失败的患者,应用四联疗法和中医药联合补救疗法不仅能获得较高的H.pylori根除率,对临床症状的改善也有良好作用,且副反应较小,值得临床推广.
