    Notes: Background: Ranitidine bismuth citrate (GR122311X) is a new drug which offers potential benefits in healing duodenal ulcers and prevention of relapse. Methods: This randomized, multi-centre double-blind study of 1620 patients compared the effect of 4 weeks of treatment with GR122311X 200 mg b.d. (n= 401), 400 mg b.d. (n= 404) or 800 mg b.d. (n= 404) or ranitidine hydrochloride 150 mg b.d. (n= 411) on the rates of duodenal ulcer healing and of overall success (ulcers healed and remaining ulcer free in the 24-week follow-up phase). Results: All four treatments were equally effective at ulcer healing (79%, 85%, 84% and 81% of patients, respectively). GR122311X 400 mg b.d. (38%) and 800 mg b.d. (37%) were significantly more effective than ranitidine hydrochloride 150 mg b.d. (32%) with respect to overall success (P = 0.050 and P = 0.030, respectively) but there was no difference with GR122311X 200 mg b.d. (31%). GR122311X caused effective, dose-related suppression of H. pylori (47%, 61% and 74%); H. pylori eradication rates were 18%, 21% and 22%. GR122311X was safe and well tolerated, with an adverse event profile similar to that of ranitidine hydrochloride 150 mg b.d. Median week 4 trough plasma bismuth levels were 1.3 ng/mL, 2.3 ng/mL and 3.3 ng/mL with GR122311X 200 mg b.d., 400 mg b.d. and 800 mg b.d. respectively. No individual plasma bismuth concentrations were of clinical concern. Conclusions: GR122311X is a safe and effective ulcer healing drug, and provides a platform on which anti-H. pylori therapy can be based.

    Notes: Aims : To study the prevalence, clinical characteristics and long-term outcome of oesophagitis in Chinese patients.Methods : Clinical and endoscopic data were collected prospectively from consecutive patients who underwent upper endoscopy between 1997 and 2001. Patients with endoscopic oesophagitis were graded according to the Los Angeles system and analysed according to their clinical presentation, endoscopic details, Helicobacter pylori status, non-steroidal anti-inflammatory drug history, co-morbidity and mortality.Results : A total of 22 628 upper endoscopies were performed in 16 606 patients. Of these, 631 (3.8%) had endoscopic oesophagitis, 14 had benign oesophageal stricture (0.08%) and 10 had Barrett's oesophagus (0.06%). Most patients (94%) had either Los Angeles grade A or grade B oesophagitis. Patients who died during follow-up had a significantly higher incidence of co-morbid illness (100% vs. 63%, P 〈 0.001). By Cox regression analysis, the presence of gastrointestinal bleeding (P = 0.008), advanced age (P = 0.004) and the use of Ryle's tube (P = 0.043) were identified to be independent factors associated with mortality.Conclusions : Complicated gastro-oesophageal reflux disease is uncommon in the Asian population. Advanced age, use of Ryle's tube and the presence of gastrointestinal bleeding are associated with a poor long-term outcome, which is a reflection of the severe underlying co-morbidity.

    Notes: Background : We have previously shown that ranitidine bismuth citrate-based, clarithromycin-containing triple therapy achieves a higher eradication rate than proton pump inhibitor-based regimens in areas with a high prevalence of metronidazole resistance.Aim : To evaluate whether this higher efficacy of ranitidine bismuth citrate over proton pump inhibitor can be extended to non-clarithromycin-containing regimens.Methods : Helicobacter pylori-positive dyspeptic patients were randomized to receive either ranitidine bismuth citrate, 400 mg, amoxicillin, 1000 mg, and metronidazole, 400 mg, or omeprazole, 20 mg, amoxicillin, 1000 mg, and metronidazole, 400 mg, each given twice daily for 1 week. H. pylori eradication was confirmed by 13C-urea breath test 5 weeks later. The side-effects of the treatments were documented.Results : Two hundred and twenty-nine patients were eligible for analysis. By intention-to-treat and per protocol analysis, the eradication rates were 77% and 79%, respectively, in the ranitidine bismuth citrate–amoxicillin–metronidazole group and 77% and 82%, respectively, in the omeprazole–amoxicillin–metronidazole group (P = 0.58 and P = 0.65). However, patients in the omeprazole–amoxicillin–metronidazole group reported a significantly higher incidence of minor side-effects when compared to those in the ranitidine bismuth citrate–amoxicillin–metronidazole group (P = 0.001).Conclusions : Ranitidine bismuth citrate–amoxicillin–metronidazole was equally as effective as omeprazole–amoxicillin–metronidazole triple therapy, and may be considered as an alternative non-clarithromycin-based regimen in the Chinese population.

    Notes: Conventional 13C-urea breath testing (13C-UBT) includes a test meal to delay gastric emptying, which, theoretically, improves the accuracy of the test. Citric acid has been proposed as the best test meal. However, recent studies have suggested that a test meal may not be necessary.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:To investigate a new 13C-UBT protocol without a test meal in a Chinese population.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:Consecutive dyspeptic patients referred for upper endoscopy were recruited. 13C-UBT was performed on two separate days with or without a test meal (2.4 Gm citric acid) and compared with the ‘gold standard’ (CLO test and histology).〈section xml:id="abs1-4"〉〈title type="main"〉Results:Two hundred and two patients were tested. Using receiver operating characteristics (ROC) analysis, the optimal delta-value and optimal measurement interval for UBT were 5% and 30 min, respectively, both with or without a test meal. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of 13C-UBT with citric acid (96.5%, 97.7%, 98.2%, 95.6%, 97.0%) were similar to 13C-UBT without a test meal (94.7%, 97.7%, 98.2%, 93.5%, 96.0%).〈section xml:id="abs1-5"〉〈title type="main"〉Conclusion:This simplified 13C-UBT protocol without a test meal produced highly accurate and reliable results in the Chinese population.

    Notes: Campylobacter pylori has been associated closely with active antral gastritis and duodenal ulcer but its pathogenetic role remains uncertain. The present longitudinal study examined, prospectively, the endoscopic antral biopsies of 45 patients with duodenal ulceration, taken before and after healing of the duodenal ulcer, during remission and at relapse. The biopsies were examined for the activity and degree of chronic inflammation of the gastritis and for the occurrence and density of C. pylori by Warthin-Starry stain. Before treatment the frequency of chronic active antral gastritis was 100% and the occurrence of C. pylori was 97%. Compared with the pre-treatment state, there was no significant change in either the frequency and severity of antral gastritis, or in the occurrence and density of the bacteria in the antral mucosa at the time the duodenal ulcer healed, during remission, or at relapse. The occurrence of the bacteria was significantly more frequent during remission, than at the time when the ulcer had healed initially (P 〈 0.05). These results suggest that the bacterium may not play an important pathogenetic role in ulcer healing and relapse, when patients are managed using an H2-blocker.

    Notes: Background : Recent studies suggest that the Helicobacter pylori eradication rate in patients with non-ulcer dyspepsia is lower when compared to patients with peptic ulcer diseases.Aim : The aim of this study was to study the efficacy of triple therapy for H. pylori infection in patients with duodenal ulcer vs. patients with non-ulcer dyspepsia.Methods : A total of 582 Chinese patients with proven H. pylori infection were recruited to receive: omeprazole 20 mg, amoxicillin 1000 mg and clarithromycin 500 mg all given twice daily for 7 days (OCA regime). Endoscopy with rapid urease test, histology and culture were performed before treatment. Post-treatment H. pylori status was determined by 13C-urea breath test. Metronidazole, clarithromycin and amoxicillin resistance was defined as minimum inhibitory concentration (MIC) of 〉8 μg/mL, 〉1 μg/mL and 〉1 μg/mL, respectively.Results : A significantly higher (intention-to-treat/per-protocol) eradication rate was found in patients with duodenal ulcer than those with non-ulcer dyspepsia (91/94% vs. 84/88% respectively, P = 0.011 and P = 0.016). Clarithromycin resistance rate was higher in patients with non-ulcer dyspepsia than those with duodenal ulcer (14% vs. 6%, P = 0.015). Clarithromycin resistance (40% vs. 5%, P 〈 0.001, OR 12, 95% CI: 5.7–24.3) and the diagnosis of non-ulcer dyspepsia (91% vs. 84%, P = 0.011, OR 2.0, 95% CI: 1.2–3.3) significantly affected the success of H. pylori eradication.Conclusion : Clarithromycin resistance accounts for the significantly lower and suboptimal H. pylori eradication rate of OCA regimen in Chinese patients with non-ulcer dyspepsia compared to those with duodenal ulcer.

    Notes: Background : We previously reported that aspirin inhibited Helicobacter pylori growth and suppressed the mutagenic effect of metronidazole.Aim : To determine the effects of a cyclo-oxygenase (COX)-2-specific inhibitor, SC-236, and a non-selective COX inhibitor, indometacin, on the growth, urease activity and antimicrobial susceptibility of H. pylori.Methods : Three H. pylori reference strains, and 18 clinical isolates were treated with SC-236 or indometacin for 24 and 48 h. Growth, urease activity and susceptibility to clarithromycin and metronidazole of the bacteria were assessed by viable colony counting, spectrophotometry and E-test respectively.Results : SC-236 and indometacin inhibited H. pylori growth in a dose-dependent manner with the lowest inhibitory concentrations of 0.03 and 0.1 mm, and the lethal concentrations of 0.09 and 0.3 mm, respectively. The numbers of CFU/mL in Brucella broth containing 0.09 mm SC-236 were 2 log lower at 24 h, and even 3 log lower at 48 h than that at 0 h (P = 0.035, compared with the vehicle control). Treatment of 0.3 mm indometacin reduced the number of CFU/mL by 1 log at 24 h compared with that at 0 h (P = 0.037 compared with the vehicle control). Helicobacter pylori urease activity began to decrease with 0.06 mm SC-236 at 24 h (P = 0.016), and 0.3 mm indometacin at 48 h (P = 0.025). MICs of metronidazole and clarithromycin against H. pylori were decreased significantly in the presence of 0.03 mm SC-236 or 0.1 mm indometacin (all P 〈 0.001).Conclusion : Both SC-236 and indometacin suppressed the growth and urease activity of H. pylori in a dose-dependent manner, and increased its susceptibility to the antibiotics.
