OBJECTIVETo observe the effect of Yiqi Huoxue Qingre Huashi Recipe (YHQHR, a recipe capable of supplementing qi, activating blood, clearing heat, and dissipating dampness) on ulcer healing and Helicobacter pylori (Hp) eradication rate in Hp positive peptic ulcer patients, and to explore coccoid Hp occurrence in the eradication.
METHODSTotally 80 Hp positive peptic ulcer patients were assigned to the treatment group and the control groups by random digit table, 40 in each group. All patients received standard triple therapy of Western medicine for 2 successive weeks. Those in the control group additionally took omeprazole enteric coated tablet, 20 mg each time, once per day for 4 successive weeks. Those in the treatment group additionally took YHQHR, twice per day for 6 successive weeks. The ulcer healing was observed and recorded by gastroscope after discontinued medication of 14 days. The effective rate of ulcer healing under endoscope was statistically calculated. Rapid urease test (RUT) was performed in one small piece of tissue from corpora ventriculi and sinuses ventriculi using 14C breathe test (UBT). Gastric juice was collected from the stomach. Hp urease gene amplification test (urea A-PCR) was performed in living tissue from gastric antrum. Results obtained from the above three test methods were recorded and assessed to decide the final eradiation rate. Gastric mucosa tissue was observed under electron microscope,attempting to find non-eradicated Hp, which was further observed.
RESULTSThe total curative effect under gastroscope was 97.5% (39/40 cases) in the treatment group, obviously higher than that in the control group (80.0%, 32/40 cases) (P < 0.05). The eradication rate of Hp was 75.0% (30/40 cases), obviously better than that of the control group (52.5%, 21/40 cases) (P < 0.05). The total positive Hp numbers after treatment was 14C UBT (12), RUT (8), and urea A-PCR (27), respectively. The Hp positive rate detected by 14C UBT and RUT was lower than the Hp positive rate detected by urea A-PCR (P < 0.05). Rod-like and coccoid Hp bacteria could be observed under electron microscope.
CONCLUSIONYHQHR combined standard triple therapy was more effective than standard triple therapy alone in promoting ulcer healing and elevating the eradication rate of Hp.

BACKGROUND/AIMS: In this study, we analysed the changes of matrix metalloproteinase-9 (MMP-9) expression in the gastric antral epithelium in respect to H. pylori eradication. METHODS: Twenty patients with H. pylori-positive chronic gastritis or peptic ulcer were studied. The expression of MMP-9 in the gastric antral biopsy specimens were compared before and after H. pylori eradication using immunohistochemical study. The positive rates and intensity of MMP-9 staining were evaluated at surface mucous cells and pyloric gland cells. RESULTS: The positive rate of MMP-9 staining in antral mucosal epithelial cells of H. pylori chronic gastritis is 63.8%. The positive rates of MMP-9 staining in the surface mucous cells and pyloric gland cells were 75.5% and 52.0% before H. pylori eradication, respectively. On the contrary, the rates were 85.5% and 82.0% after eradication. The MMP-9 overexpression in the pyloric gland cells were noticeably increased after H. pylori eradication. Strong positive staining of MMP-9 was increased significantly after H. pylori eradication in the pyloric gland cells. CONCLUSIONS: These results suggest that MMP-9 over-expression is associated with H. pylori infection as a host inflammatory response. The increased expression after H. pylori eradication indicates that MMP-9 may have a important role in remodeling or early tissue repairing process of gastric mucosa.

Shen Shong CHANG ; Hsiao Yun HU
Gut and Liver 2015;9(3):346-352
BACKGROUND/AIMS: The connection between Helicobacter pylori and complicated peptic ulcer disease in peptic ulcer bleeding (PUB) patients taking nonsteroidal anti-inflammatory drugs has not been established. In this study, we sought to determine whether delayed H. pylori eradication therapy in PUB patients increases complicated recurrent peptic ulcers. METHODS: We identified inpatient PUB patients using the Taiwan National Health Insurance Research Database. We categorized patients into early (time lag < or =120 days after peptic ulcer diagnosis) and late H. pylori eradication therapy groups. The Cox proportional hazards model was used. The primary outcome was rehospitalization for patients with complicated recurrent peptic ulcers. RESULTS: Our data indicated that the late H. pylori eradication therapy group had a higher rate of complicated recurrent peptic ulcers (hazard ratio [HR], 1.52; p=0.006), with time lags of more than 120 days. However, our results indicated a similar risk of complicated recurrent peptic ulcers (HR, 1.20; p=0.275) in time lags of more than 1 year and (HR, 1.10; p=0.621) more than 2 years. CONCLUSIONS: H. pylori eradication within 120 days was associated with decreased complicated recurrent peptic ulcers in patients with PUB. We recommend that H. pylori eradication should be conducted within 120 days in patients with PUB.

BACKGROUND/AIMS: Helicobacter pylori (H. pylori) treatments fail at least in 10-20% of patients. However, retreatment strategies after failure of initial treatment have not been established. This study was conducted to evaluate the eradication rate of retreatment choices. METHODS: Twenty-seven peptic ulcer patients who were retreated with OAC (omeprazole + amoxicillin + clarithromycin) or BMT (bismuth + metronidazole + tetracycline) after failure of BMT or OAC were included. Quadruple therapy (omeprazole + BMT) was also tried after failure of two successive triple therapies. Furthermore, the effect of resistance of metronidazole or clarithromycin on the eradication of H. pylori was evaluated. RESULTS: Among 13 patients who were retreated with OAC after failure of BMT regimen, H. pylori was eradicated in 10 patients (76.9%). Among 14 patients retreated with BMT after failure of OAC regimen, H. pylori was eradicated in 11 patients (78.6%). Resistance of H. pylori to metronidazole or clarithromycin decreased the efficacy of BMT or OAC, respectively. CONCLUSIONS: Eradication regimen should be decided considering the resistance to H. pylori. However, in case of unknown state of resistance, OAC can be chosen if BMT fails. Similarly, BMT can be tried in cases that OAC therapy failed. After failures of both triple therapies, quadruple therapy can be tried as the next step.

BACKGROUND/AIMS: It is not clear whether the anti-secretory therapy should be continued for symptomatic relief and ulcer healing before or after the eradication of H. pylori in patients with peptic ulcer disease. The aim of this study was to evaluate the effectiveness of additional anti-secretory therapy before or after H. pylori eradication in peptic ulcer disease. METHODS: Thirty eight patients with H. pylori-positive active peptic ulcer were included. Patients were randomly allocated into 3 groups; standard 1-week triple therapy followed by omeprazole (20 mg, qd) for 3 weeks (group A), standard 1-week triple therapy only (group B), and omeprazole (20 mg, qd) for 3 weeks followed by 1-week triple therapy (group C). Endoscopy with the rapid urease test and histology for H. pylori was performed 4-8 weeks after the completion of treatment. The symptom was scored by a visual analog scale. RESULTS: Of the 38 patients, 10 were excluded from the per-protocol analysis of this study. The H. pylori eradication rates were 87.5% (group A), 80.0% (group B) and 90.0% (group C) respectively. The peptic ulcer healing rates were 100% in group A, 70.0% in group B, and 90.0% in group C. There was no difference in H. pylori eradication rates and ulcer healing rates among three groups (p>0.05). Symptom score differences between pre-treatment and post-treatment group were not significantly different (p>0.05). CONCLUSIONS: The standard one week triple therapy with or without 3-weeks anti-secretory treatment with omeprazole before or after the therapy does not affect H. pylori eradication rates, peptic ulcer healing rates, and symptom score improvement.

6.Progress in the treatment of Helicobacter pylori infection.
Journal of Central South University(Medical Sciences) 2014;39(9):981-988
Helicobacter pylori (H. pylori) infection is highly associated with the occurrence of gastrointestinal diseases, including gastric inflammation, peptic ulcer, gastric mucosa-associated lymphoid-tissue lymphoma and gastric cancer. It is a key strategy to prevent and treat these diseases by eradicating H. pylori. Due to the increasing rates of antimicrobial resistance of clarithromycin and metronidazole, the eradication rate of standard triple therapy is less than 80% in recent years. On the basis of traditional triple therapy, combination with some treatments, such as probiotics, mucoprotective agents, Chinese medicine and oral clean, can improve the H. pylori eradication rate.

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.

OBJECTIVETo evaluate the prevalence of Helicobacter pylori (H.pylori) resistance to metronidazole among three populations in Yunnan.
METHODSSusceptibilities to metronidazole among 109 H. pylori strains (33 H. pylori strains from Han, 31 H. pylori strains from Bai and 45 H. pylori strains from Naxi ethnic populations) were tested by Epsilometer test (E-test).
RESULTSIn 109 H. pylori strains, the overall metronidazole resistance rate was 67.89%. There were no significant difference in the metronidazole resistant rates of H. pylori among Han, Bai, Naxi populations Yunnan in terms of the distribution on age and upper gastroduodenal diseases. In the facet of gender, metronidazole resistant rate of H. pylori was significantly lower in Han males than in females (chi2=5.304, P=0.027), but not seen in the Bai or Naxi peoples.
CONCLUSIONMetronidazole resistance rate of H. pyloriin Yunnan was high, but no significant difference was found among Han, Bai, Naxi peoples in the province.

BACKGROUND/AIMS: The increasing trend of antibiotic resistance emphasizes the need for the assessment of eradication rate of first and second-line therapy for Helicobacter pylori (H. pylori) infection. The reinfection rate depends on the geographical, national, or socioeconomic status of the patients. The aim of this study was to evaluate the recent 5-year changes of eradication rates and the reinfection rates after the successful eradication of Helicobacter pylori infection for 3-years follow-up in Bucheon, Korea. METHODS: From February 2001 to August 2006, 3,267 patients with H. pylori-positive peptic ulcer disease received the first-line therapy for 7 days. The 317 patients who failed to the first-line therapy received the second-line therapy for 7 days. The 167 patients with 3-years follow-up after the successful eradication were included. (13)C-urea breath tests or rapid urease tests and histologies were assessed to determine the H. pylori status after the eradication. RESULTS: The eradication rate of first-line therapy was 83.7% in 2001, 83.4% in 2002, 83.7% in 2003, 85.9% in 2004, 87.2% in 2005, and 81.8% in 2006 by per protocol analysis (PP), respectively. The eradication rate of second-line therapy was 80.0% in 2002, 86.8% in 2003, 89.7% in 2004, 98.0% in 2005, and 78.8% in 2006 by PP. The cumulative reinfection rate was 6.0%. The annual reinfection rate was 2.0%. The recurrence rate of peptic ulcer was 17.2% in the patients without reinfection and 50% with reinfection. CONCLUSIONS: The eradication rate for H. pylori have not changed in the recent 5-years. The annual reinfection rate was low. The successful eradication of H. pylori was effective for preventing the recurrence of peptic ulcers.

BACKGROUND/AIMS: This study was performed to evaluate whether the prevalence rates of primary antibiotic resistance in Helicobacter pylori (H. pylori) isolates and the eradication rate of H. pylori could be different between cancer and non-cancer patients. METHODS: H. pylori were isolated from gastric mucosal biopsy specimens obtained from 269 Koreans, who did not have any eradication therapy history and were diagnosed as one of the following diseases; chronic gastritis, benign gastric ulcer, duodenal ulcer or gastric cancer. The susceptibilities of the H. pylori isolates to amoxicillin, clarithromycin, metronidazole, tetracycline, azithromycin, ciprofloxacin, levofloxacin and moxifloxacin were examined with the agar dilution method. In addition, eradication rate of H. pylori was evaluated. RESULTS: There was no significant difference in the primary antibiotic resistance to above eight antibiotics among chronic gastritis, peptic ulcer disease and gastric cancer. Furthermore there was no difference of antibiotic resistance between cancer and non-cancer patients, and there was no difference of eradication rate of H. pylori according to disease. CONCLUSIONS: Primary antibiotic resistance and H. pylori eradication rate were not different between cancer and non-cancer patients.
