五种HP根除方案对高原部队HP感染的病人治疗效果的比较

为了筛选适合于高原部队防治由于 HP 感染所致的上消化道疾病的 HP 根除治疗方案,设计了5种不同的治疗方案,并对胃镜检查证实的140名 HP 阳性的患者进行随机分组治疗,治疗结束后4周采用(14)~C-尿素呼吸试验复查,溃疡患者胃镜复查并行 HP 快速尿素酶试验和病理检查。结果表明:以德诺为主的2号和3号四联方案Hp 根除率分别为92.23%和91.67%,但不良反应较多;4号方案(雷尼替丁150mg2/天,甲硝唑200mg4/天,呋喃唑酮100mg4/天)HP 根除率为83.33%,但与2号和3号四联方案比较并无显著差异(P>0.05),且不良反应少,依从性好,药品成本低。因此,根据我们的结果,4号方案是一种较为理想的并适合于高原基层部队的 HP 根除治疗方案,值得在临床推广应用。

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.

Triple therapy with clarithromycin, amoxicillin and omeprazole for Helicobacter pylori eradication in children and adolescents

BACKGROUND: Helicobacter pylori infection presents high prevalence in developing countries, but there are few pediatric assays evaluating antimicrobial treatment. OBJECTIVE: The aim of this study was to investigate Helicobacter pylori eradication rate using a short regimen (7 and 10 days) of triple therapy with clarithromycin, amoxicillin and omeprazole. PATIENTS AND METHODS: Twenty-five Hp positive patients who presented severe epigastralgia, were submitted to antimicrobial treatment with amoxicillin (50 mg/kg/day--maximum dose 1 g bid), clarithromycin (30 mg/kg/day--maximum dose 500 mg bid) and omeprazole (0.6 mg/kg/day--maximum dose 20 mg bid) during 7 or 10 days. After 2 months, clinical symptoms were evaluated and gastric biopsies were taken to test Hp eradication. RESULTS: Overall eradication rate was achieved in 16/25 patients (64%--IC(95% = 45-83%), in 11/15 (73%--IC(95%) = 51-95%) patients who used 10 days therapy course and in 5/10 (50%--IC(95%) = 19-81%) who used 7 days therapy course. Eradication drugs were well accepted and adverse effects were reported in two patients (8%). CONCLUSIONS: This triple therapy regimen had moderate efficacy (64%). The data suggests that 10 days therapy course achieves better eradication rate (73%) than 7 days course (50%) to treat Hp infection in our population.     

十二指肠溃疡患者根除幽门螺杆菌后抑酸维持治疗的疗效研究

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。     

A Comparative Trial of Ranitidine 300 mg at Night with Ranitidine 150 mg Twice Daily in the Treatment of Duodenal and Gastric Ulcer

A multicenter double-blind comparative trial of oral ranitidine, 300 mg hs versus 150 mg bid, was conducted in 89 patients with duodenal ulcer (DU) and 54 with gastric ulcer (GU). Antacid tablets were prescribed prn. After 4 wk of treatment there were no statistically significant differences in the ulcer healing rates associated with the once daily (DU 86.4%, GU 62.5%) and the twice daily (DU 84.4%, GU 73.3%) regimens. Antacid consumption, by both DU and GU patients, was higher in the 150 mg bid group, but the differences did not achieve statistical significance. Further improvement in cumulative healing rates in response to both treatment regimens was observed following a second 4-wk treatment for those patients whose ulcers had failed to heal during the 1st month. Smoking adversely affected the rate of ulcer healing in DU patients, but had no significant effect on GU healing. No serious adverse effects or biochemical abnormalities were observed. Ranitidine 300 mg hs appears to be equally safe and effective as the standard regimen of 150 mg bid in the short-term treatment of uncomplicated gastroduodenal ulcer.     

Gastroesophageal reflux before and after Helicobacter pylori eradication. A prospective study using ambulatory 24-h esophageal pH monitoring

The aim of this study was to assess prevalence of GERD before and after Helicobacter pylori (HP) eradication utilizing 24-h esophageal pH/manometry studies. Helicobacter pylori status was confirmed by the Campylobacter like organism test. Those testing positive underwent 24-h pH/manometry followed by HP eradication therapy and urea breath test. Patients were followed up at 6 months and then at 1 year when they underwent a repeat 24-h pH/manometry. Twenty patients, 10 with non-ulcer dyspepsia (NUD) and 10 with duodenal ulcer (DU) were enrolled, though only 10 patients attended for a repeat 24-h pH/manometry study. The patients were well matched, though patients with NUD had a significantly higher symptom score at entry compared with the DU group (8.5 vs 5.7, P < 0.05). The pH and esophageal manometry data were similar in the two groups. Overall nine patients (45%; DU = 5, NUD = 4) had evidence of GERD prior to HP eradication and it persisted one year after cure of the infection. The reflux disease occurred in the presence of normal LES pressure (mean 15.6 +/- 3.3 mmHg). New onset GERD was uncommon after cure of HP infection, occurring in only one patient with NUD. Overall HP eradication had no impact on percentage of time pH < 4 (4.69 +/- 3 vs 4.79 +/- 3), episodes > 5 min (9.8 +/- 16 vs 15.5 +/- 25.3) and Johnson DeMeester Score (16.8 +/- 7.5 vs 26.8 +/- 18). In addition successful cure of HP produced no significant changes in LES pressure (17.9 +/- 3.8 mmHg vs 19.3 +/- 4.6 mmHg), and other esophageal manometry data. Half of HP-positive patients with NUD and DU have evidence of GERD before HP eradication. This persists after successful cure of the infection. New onset GERD occurs very uncommonly one year after HP eradication.
