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.     

One-year follow-up study of Helicobacter pylori eradication rate with 13C-urea breath test after 3-d and 7-d rabeprazole-based triple therapy

AIM: To investigate the long-term role of a 3-d rabeprazole-based triple therapy in patients with Helicobacter pylori (H pylori)-infected active peptic ulcers. METHODS: We prospectively studied 115 consecutive patients with H pylori-infected active peptic ulcers. H pylori infection was confirmed if any two of H pylori DNA, histology, and rapid urease test were positive. Patients were assigned to either an open-labeled 3-d course of oral amoxicillin 1 000 mg b.i.d., clarithromycin 500 mg b.i.d., and rabeprazole 20 mg b.i.d., or 7-d course of oral amoxicillin 1 000 mg b.i.d., clarithromycin 500 mg b.i.d., and rabeprazole 20 mg b.i.d. Subsequently, all patients received oral rabeprazole 20 mg once daily until the 8th wk. Three months after therapy, all patients were followed-up endoscopically for the peptic ulcer, H pylori DNA, histology, and rapid urease test. One year after therapy, H pylori infection was tested using the 13C-urea breath test. RESULTS: The ulcer healing rates 3 mo after therapy were 81.0% vs 75.4% for the 3-d and 7-d groups [intention-to-treat (ITT) analysis, P=0.47] respectively, and 90.4% vs 89.6% for the 3-d and 7-d groups [per-protocol (PP) analysis, P=0.89] respectively. The eradication rates 3 mo after therapy were 75.9% vs 73.7% for the 3-d and 7-d groups (ITT, P=0.79) respectively, and 84.6% vs 87.5% for the 3-d and 7-d groups (PP, P=0.68) respectively. One year after therapy, seventy-five patients returned to receive the 13C-urea breath test, and the eradication rates were 78.4% vs 81.6% in 3-d and 7-d groups (PP, P=0.73) respectively. CONCLUSION: Our study showed the eradication rates against H pylori infection 3 and 12 mo after triple therapy were not different between the 3-d and 7-d rabeprazole-based groups. Therefore, the 3-d rabeprazole-based triple therapy may be an alternative treatment for peptic ulcers with H pylori infection.

4-day triple therapy with rabeprazole, amoxicillin and clarithromycin in the eradication of Helicobacter pylori in patients with peptic ulcer disease--A pilot study

BACKGROUND: It is well established that a 7-day triple therapy achieves eradication rates of Helicobacter pylori between 90% and 95%. Due to a lack of highly effective short-term eradication studies the aim of the present pilot study was to investigate the effect of a 4-day triple therapy with the new proton pump inhibitor rabeprazole (20 mg b. i. d.) in combination with clarithromycin (500 mg b. i. d.) and amoxicillin (1 g b. i. d.) without acid-suppressive pre-treatment in patients with H. pylori-related peptic ulcer disease. METHODS: 20 patients (11 men, 9 women) with endoscopically diagnosed peptic ulcers (gastric ulcer: n = 5; duodenal ulcer: n = 9; combined gastric and duodenal ulcer: n = 2, gastric or duodenal ulcer scars: n = 4) and H. pylori infection were consecutively recruited. The Helicobacter pylori status was assessed by means of histology, CLO (urea-) test and C13-urea breath test (C13-UBT) at entry. Treatment success was determined by C13-UBT 35-42 days after end of treatment. RESULTS: In 18 out of the 20 patients (90%) [77-100%, 95%-CI] a negative test result was found in C13-UBT 35-42 days after treatment. The 2 patients who remained H. pylori-positive had a duodenal ulcer. CONCLUSION: A 4-day triple therapy of rabeprazole in combination with clarithromycin and amoxicillin seems to be highly effective in eradicating H. pylori and well tolerated in patients with gastric and duodenal ulcer disease. The achieved eradication rate of 90% is comparable with the established 7-day triple therapy regimens. On the basis of these results and considering costs, side effects and compliance a large number of patients should be enrolled in a confirmatory 4-day eradication trial.     

Comparison of sequential and 7-, 10-, 14-d triple therapy for Helicobacter pylori infection

AIM: To compare the effectiveness of sequential therapy for Helicobacter pylori (H. pylori) infection with that of triple therapy of varying durations.METHODS: The 460 patients enrolled in this study had H. pylori-associated gastritis or a gastric or duodenal ulcer. After screening, H. pylori-infected patients were randomly assigned to receive either conventional triple therapy for 7, 10 or 14 d, or a new 10-d sequential therapy. Each of the 4 treatment groups included 115 patients. The outcomes of eradication therapy were assessed 4 wk after treatment by the urea breath test and histology.RESULTS: The overall eradication rate was 81.0%, and eradication rates were 75.7% for 7-d conventional triple therapy, 81.9% for 10-d conventional triple therapy, 84.4% for 14-d conventional triple therapy, and 82.0% for 10-d sequential therapy. Neither intention-to-treat analysis nor per protocol analysis showed significant differences in eradication rates using sequential therapy or the standard triple therapy (P = 0.416 and P = 0.405, respectively).CONCLUSION: There are no significant differences between 10-d sequential eradication therapy for H. pylori and any duration of standard triple treatment in Korean patients.     

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.

One Week of Esomeprazole Triple Therapy vs. 1 Week of Omeprazole Triple Therapy Plus 3 Weeks of Omeprazole for Duodenal Ulcer Healding in <Emphasis Type="Italic">Helicobacter pylori</Emphasis>-Positive Patients

In this randomized, double-blind, multicenter study, H. pylori-positive patients with an active duodenal ulcer (DU) received esomeprazole, 20 mg twice daily (bid), or omeprazole, 20 mg bid, with amoxicillin, 1000 mg bid, and clarithromycin, 500 mg bid, for 1 week (EAC and OAC, respectively). Patients received an additional 3 weeks of either placebo or omeprazole, 20 mg once daily (od), in the EAC and OAC groups, respectively. The intent-to-treat population included 374 patients (EAC, 186; OAC, 188). Four-week DU healing rates were similar in the EAC+placebo and OAC+omeprazole groups: 74% and 76%, respectively. DU healing rates at 8 weeks were 87% for EAC+placebo and 88% for OAC+omeprazole. H. pylori eradication rates were 75% and 79% for EAC and OAC, respectively. Both regimens were well tolerated. A 1-week regimen of esomeprazole-based H. pylori eradication triple therapy was as effective for DU healing and eradication of H. pylori as omeprazole-based triple therapy followed by an additional 3 weeks of monotherapy.

The prolongation of triple therapy for Helicobacter pylori does not allow reaching therapeutic outcome of sequential scheme: a prospective, randomised study

BACKGROUND AND AIM: One-week triple therapy for Helicobacter pylori revealed, during these last few years, a decrease in the eradication rate, so that the prolongation of its duration has been proposed. A sequential scheme recently showed very satisfactory results. We performed a prospective randomised study with the aim of either evaluating whether the triple therapy prolongation may improve its effectiveness and comparing its outcome with that of sequential regimen. PATIENTS AND METHODS: Three hundred and forty-two H. pylori positive patients completed the study. They were randomised to receive one of the following treatments: (i) a 7-day triple therapy comprising of rabeprazole (20 mg, b.i.d.) plus clarithromycin (500 mg, b.i.d.) and amoxycillin (1 g, b.i.d.); (ii) a 10-day triple therapy comprising the same scheme; (iii) a 10-day sequential regimen comprising of rabeprazole (20 mg, b.i.d.) plus amoxycillin (1 g, b.i.d.) for 5 days followed by rabeprazole (20 mg, b.i.d.) plus clarithromycin (500 mg, b.i.d.) and tinidazole (500 mg, b.i.d.) for the next 5 days. Therapeutic results were expressed using both intention-to-treat and per protocol analyses with 95% confidence intervals. A model of multivariate logistic regression analysis was performed using therapeutic outcome as a dependent variable and including endoscopic finding, smoking habit, age and sex as candidates for the model. RESULTS: Sequential regimen showed a significant gain in the eradication rate as compared to the 7-day (P < 0.0001) and the 10-day (P < 0.01) triple therapies, respectively. Overall eradication was lower in smokers than in non-smokers, but the difference remained significant only in the 7-day triple therapy (P < 0.01). Additionally, the overall eradication was higher in peptic ulcer than dyspepsia (P < 0.01), even if this difference was significant only for both triple therapies. CONCLUSIONS: Seven-day triple therapy achieves disappointing eradication rates in dyspeptics and smokers. Prolonging triple therapy to 10 days does not significantly improve the eradication rate. The novel 10-day sequential regimen is more effective and equally tolerated than the 10-day triple therapy.     

Efficacy of 14-d vs 7-d moxifloxacin-based triple regimens for second-line Helicobacter pylori eradication

AIM: To evaluate the efficacy of the 14-d moxifloxacinbased triple therapy for the second-line eradication of Helicobacter pylori(H. pylori) infection.METHODS: Between 2011 and 2013, we conducted a retrospective review of the medical records of 160 patients who had experienced failure of their first-line proton pump inhibitor-based eradication therapy and subsequently received the moxifloxacin-based triple therapy as a second-line eradication treatment regimen. The patients who were treated with the moxifloxacinbased triple therapy(oral 20 mg rabeprazole b.i.d., 1000 mg amoxicillin b.i.d., and 400 mg moxifloxacin q.d.) for 7 d were assigned to the RAM-7 group(n = 79) while those who took them for 14 days were assigned to RAM-14 group(n = 81). The eradication rates for both groups were determined by intentionto-treat(ITT) and per-protocol(PP) analyses. ITT analysis compared the treatment groups as originally allocated while the PP analysis including only those patients who had completed the treatment as originally allocated. Successful eradication therapy for H. pylori infection was defined as the documentation of a negative 13C-urea breath test 4 wk after the end of the eradication treatment.RESULTS: The overall ITT eradication rate was 76.2%(122/160). The final ITT eradication rates were 70.8%(56/79; 95%CI: 63.3%-77.1%) in the RAM-7 group and 81.4%(66/81; 95%CI: 74.6%-88.3%) in the RAM-14 group(P = 0.034). The overall PP eradication rate was 84.1%(122/145), and the final PP eradication rates were 77.7%(56/72; 95%CI: 70.2%-85.3%) in the RAM-7 group and 90.4%(66/73; 95%CI: 82.8%-98.1%) in the RAM-14 group(P = 0.017). The H. pylori-eradication rates in the RAM-14 group were significantly higher compared with that of the RAM-7 group according to both the ITT(P = 0.034) and the PP analyses(P = 0.017). Both groups exhibited good treatment compliance(RAM-7/RAM-14 group: 100%/100%). The adverse event rates were19.4%(14/72)and 20.5%(15/73)in the RAM-7 and RAM-14 groups,respectively(P=0.441).Adverse events occurred in 14 of the 72 patients(19.4)in the RAM-7 group and in 15 of the 73 patients(20.5)in the RAM-14 group.No statistically significant differences(P=0.441)were observed.CONCLUSION:The 14-d moxifloxacin-based triple therapy is a significantly more effective secondline eradication treatment as compared to the 7-d alternative for H.pylori infection in South Korea.

Helicobacter pylori eradication with moxifloxacin-containing therapy following failed first-line therapies in South korea

AIM:To investigate moxifloxacin-containing triple therapy as second-line treatment for Helicobacter pylori(H.pylori)infection following failed first-line treatment.METHODS:The sample included 312 patients for whom first-line treatment failed between January 2008and May 2013;27 patients were excluded,and a total of 285 patients received 7-or 14-d moxifloxacincontaining triple therapy as second-line treatment for H.pylori infection.First line regimens included 7-d standard triple(n=172),10-d bismuth-containing quadruple(n=28),14-d concomitant(n=37),or14-d sequential(n=48)therapy.H.pylori status was evaluated using 13C-urea breath testing 4 wk later,aftercompletion of the treatment.The primary outcome was the H.pylori eradication rate analyzed using intentionto-treat(ITT)and per protocol(PP)analyses.The secondary outcome was the occurrence of serious adverse events.Demographic and clinical factors were analyzed using Student’s t-tests and Pearson’sχ2 tests according to first-and second-line regimens.A P value of less than 0.05 was considered statistically significant.RESULTS:The eradication rate of moxifloxacincontaining triple therapy was 68.4%(ITT;95%CI:62.8-73.5)and 73.9%(PP;95%CI:68.3-78.8).The eradication rate was significantly higher with 14 d compared to 7 d of treatment(77.5%vs 62.5%,P=0.017).Peptic ulcer patients had a higher eradication rate than the patients without ulcers(82.9%vs 70.6%,P=0.046).The demographic and clinical characteristics were not significantly different between the groups according to first-line therapies.ITT and PP analyses of the moxifloxacin-containing triple therapy indicated the following eradication rates:70.9%(95%CI:63.8-77.2)and 77.2%(95%CI:70.1-83.1)for standard triple;67.9%(95%CI:51.5-84.2)and 67.9%(95%CI:51.5-84.2)for bismuth-containing quadruple;60.4%(95%CI:46.3-73.0)and 70.7%(95%CI:54.0-80.9)for sequential;and 67.6%(95%CI:51.5-80.4)and67.6%(95%CI:51.5-80.4)for concomitant therapy.There were no statistically significant differences in the efficacy of the first-line regimens(P=0.492).The most common adverse event was diarrhea.There were no serious adverse events and no significant differences in the frequency of side effects between the first-and second-line regimens(28.7%vs 26.1%,respectively).CONCLUSION:Moxifloxacin-containing triple therapy as second-line treatment resulted in low eradication rates.There were no differences in the efficacy between the first-line regimens in South Korea.     

Can Helicobacter pylori eradication regimens be shortened in clinical practice? An open-label, randomized, pilot study of 4 and 7-day triple therapy with rabeprazole, high-dose levofloxacin, and tinidazole

BACKGROUND: Rabeprazole is a proton pump inhibitor which is particularly suitable for use in short-term Helicobacter pylori eradication treatment. Levofloxacin-based H. pylori eradication regimens have shown good efficacy and very few side effects. Shorter treatment and absence of significant side effects should improve compliance to therapy and increase the Hp H. pylori eradication rate. AIMS: To evaluate the effectiveness of 2 rabeprazole-based H. pylori eradication regimens in an open-label, randomized study carried out in a clinical practice setting. METHODS: One hundred sixty-nine consecutive, treatment-naive patients with H. pylori infection were randomized to receive rabeprazole (20 mg, bid), levofloxacin (500 mg, bid), and tinidazole (500 mg, bid) for either 4 [4-d rabeprazole, levofloxacin, tinidazole (RLT), n=85] or 7 days (7-d RLT, n=84). Before treatment, all patients underwent upper digestive endoscopy. Cure rates were assessed by means of C-urea breath test. and were compared with the eradication rate obtained with standard triple therapy in our Unit (ie, 78%) and average eradication rate reported in the literature (ie, 79%). RESULTS: The intention-to-treat eradication rates were 94% [87% to 98%, 95% confidence interval (CI)] and 95% (88% to 99%, 95% CI) in the 4-day RLT and 7-day RLT regimens, respectively, whereas per-protocol eradication rates were 95% (88% to 99%, 95% CI) in the 4-day RLT and 96% (90% to 99%, 95% CI) in the 7-day RLT. Both treatment regimens obtained significantly higher eradication rates as compared with standard triple therapy. The 4-day RLT showed significantly fewer side effects. CONCLUSIONS: In a clinical practice setting, both 4-day and 7-day rabeprazole, high-dose levofloxacin, tinidazole-based regimens achieved relevant H. pylori eradication rates in treatment-naive patients. The lower number of side effects makes the shorter treatment regimen preferable over the conventional 7-day treatment.     

One week of treatment with esomeprazole-based triple therapy eradicates Helicobacter pylori and heals patients with duodenal ulcer disease.

BACKGROUND: Proton pump inhibitor (PPI) monotherapy is commonly continued for 3 weeks after Helicobacter pylori eradication with PPI-based triple therapy regimens to ensure duodenal ulcer (DU) healing. This randomized, double-blind, multicentre study evaluated whether only 1 week of triple therapy with the new PPI esomeprazole was sufficient to ensure high rates of ulcer healing and H. pylori eradication. METHODS: A total of 446 H. pylori-positive patients with active DU received twice daily treatment with esomeprazole 20 mg (n = 222) or omeprazole 20 mg (n = 224) in combination with amoxicillin 1 g and clarithromycin 500 mg for 1 week (EAC and OAC, respectively). Patients in the OAC group then received 3 weeks' monotherapy with omeprazole 20 mg once daily; those treated with EAC received placebo. Ulcer healing was assessed by endoscopy on completion of therapy and H. pylori status was assessed by (13)C-urea breath testing and histology 4-6 weeks later. RESULTS: Ulcer healing rates (95% CI) for intention-to-treat and per-protocol populations were: EAC + placebo 91% (87-95%) and 94% (90-97%); OAC + omeprazole 92% (88-95%) and 96% (92-98%). Corresponding H. pylori eradication rates were: EAC + placebo 86% (81-90%) and 89% (84-93%); OAC + omeprazole 88% (83-92%) and 90% (85-93%). Both eradication regimens were well tolerated, and patient compliance was high. CONCLUSIONS: A 1-week regimen of esomeprazole-based triple therapy is sufficient for DU healing and H. pylori eradication in patients with DU disease.     

Seven-day proton pump inhibitor, amoxicillin and clarithromycin triple therapy. factors that influence Helicobacter pylori eradications success.

AIM: To evaluate which factors influence eradication success with standard triple therapy for Helicobacter pylori. PATIENTS AND METHODS: A prospective study was made of 891 patients infected by H. pylori and diagnosed with duodenal ulcer (n=422), gastric ulcer (n=221), or functional dyspepsia (n=248). Initially, an endoscopy with biopsies of antrum and body (haematoxylin-eosin stain), and a 13C-urea breath test were performed. All patients were treated for seven days with either omeprazole 20 mg twice daily in 442 patients (OCA) or pantoprazole 40 mg twice daily in 449 patients (PCA), associated to clarithromycin (500 mg twice a day) and amoxicillin (1 g twice a day). Two months after completing therapy urea breath test was repeated to confirm eradication. RESULTS: Mean age +/- SD was 51.6 +/- 15 years, 61% were male. Overall eradication rate was 73.7% (95% CI 69-77%) and 80.8% (77-84%) with OCA and PCA therapy, respectively, showing significant difference between treatment regimens (chi 2 =6.3; p= 0.01). As refers to underlying diseases, H. pylori eradication was achieved in 77.4% (74-80%) of peptic ulcers and 77% (71-82%) of functional dyspepsia (p=n.s.). With our two treatment regimens (OCA/PCA) eradication success was 74/81% in peptic ulcer (p=0.03), and 72/80% in functional dyspepsia (p=0.1). In the multivariate analysis, type of therapy was the only variable that correlated with eradication success (odds ratio 1.5; 95% CI: 1.1-2.1) (chi2 model: 6,4; p=0.01). CONCLUSIONS: Standard triple therapy containing a proton pump inhibitor, clarithromycin and amoxicillin for seven days achieves in our community a moderate eradication success; this result could improve by using pantoprazole instead of omeprazole. This therapy is equally effective in patients with peptic ulcer and functional dyspepsia.     

Comparison of 1 and 2 weeks of omeprazole, amoxicillin and clarithromycin treatment for Helicobacter pylori eradication: the HYPER Study

BACKGROUND: Triple therapy is recommended for Helicobacter pylori eradication, yet consensus on the duration of treatment is lacking. AIM: To compare the efficacy and safety of 1- and 2-week regimens of omeprazole, amoxicillin and clarithromycin in a large, multicentre, double-blind and randomised study. METHODS: A total of 909 H pylori-positive patients with duodenal ulcer, enrolled in 81 endoscopy units in Italy, were randomised to receive omeprazole, amoxicillin and clarithromycin for either 1 week (OAC1W) or 2 weeks (OAC2W) or omeprazole and amoxicillin for 2 weeks. H pylori eradication was assessed by histological examination and carbon-13 urea breath test 4 weeks after treatment. RESULTS: Both the intention-to-treat (ITT; n = 907) and per protocol (PP; n = 661) analyses showed no significant differences between the eradication rates of OAC1W (ITT 79.7%; PP 83.6%) and OAC2W (ITT 81.7%; PP 84.9%; ITT p = 0.53; PP p = 0.71). Both triple omeprazole, amoxicillin and clarithromycin regimens gave significantly higher eradication rates compared with omeprazole and amoxicillin treatment (ITT 44.6%; PP 42.8%; p<0.001). Poor compliance was reported in 18.6%, 17.3% and 15.1% (p = 0.51) of patients for OAC2W, OAC1W and omeprazole and amoxicillin, respectively. Adverse events occurred in 9.9% and 9.6% (p = 0.88) of patients for OAC2W and OAC1W, respectively, and in 5.9% for omeprazole and amoxicillin (p = 0.11). CONCLUSIONS: 1-week and 2-week triple treatments for H pylori eradication are similar in terms of efficacy, safety and patient compliance.     

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.     

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). CONCLUSION: Killing Helicobacter pylori quadruple therapy can not only promote the eradication of H pylori and healing quality of ulcer but also reduce recurrence rate of ulcer.
