BACKGROUND/AIMS: The aim of this study was to determine the one-year outcome of an eradication therapy with ranitidine bismuth citrate and antibiotics in Helicobacter pylori-positive duodenal ulcer patients in respect to ulcer and Helicobacter pylori relapse rates. METHODOLOGY: This multicenter, randomized, double-blind study involved 648 duodenal ulcer patients and had been carried out to compare the following regimens: ranitidine bismuth citrate b.i.d. co-prescribed with either clarithromycin 250 mg q.i.d. or clarithromycin 500 mg b.i.d. or clarithromycin 500 mg b.i.d. plus metronidazole 400 mg b.i.d. for 2 weeks, followed by a further 14 days of treatment with ranitidine bismuth citrate 400 mg b.i.d. to facilitate ulcer healing. H. pylori eradication was assessed by 13C-urea breath test and histology at least 4 weeks, 26 weeks and 52 weeks after the end of treatment. Ulcer relapse and H. pylori status were assessed 4 weeks, 26 weeks and 52 weeks post-treatment or if ulcer symptoms recurred. For the remainder of the follow-up period only serious adverse events were collected. RESULTS: At 12 months data of 438 (69%) patients were evaluable. The observed H. pylori eradication rates were 88-91%. H. pylori relapse rates were 2.1% after 26 weeks and 3.9% after 52 weeks. At the week 26 visit 26 patients (5.6%) and at the week 52 visit 25 patients (5.7%) had documented gastroesophageal reflux disease. CONCLUSIONS: Our data confirm the reduction of duodenal ulcer relapses after the cure of Helicobacter pylori infection. 相似文献

复合自适应滤波器用于体感诱发电位信噪比的提高 总被引:1,自引:0,他引:1
本研究以可靠、快速提取体感诱发电位为目标,试图解决相干叠加方法既费时又不能反映体感诱发电位时变特征的缺点。运用以自适应噪声减法器和自适应增强器为基础构造的复合自适应滤波器提取体感诱发电位。仿真实验表明,运用复合自适应滤波器可实现从强噪声背景中快速提取体感诱发电位,能更快地识别体感诱发电位的潜伏期及幅值,并且系统性能稳定。 相似文献

BACKGROUND: Partially hydrolysed guar gum (Benefiber) added to a diet is fermented in the colon, producing short chain fatty acids, which improve intestinal function, including colonic salt and water absorption. AIMS: To evaluate the effect of Benefiber supplemented comminuted chicken diet in the treatment of persistent diarrhoea. METHODS: One hundred and sixteen children (aged 5-24 months), presenting to Dhaka Hospital with a history of watery diarrhoea for more than 14 days (persistent diarrhoea), were randomised to receive either: (1) comminuted chicken diet with Benefiber (study diet); or (2) comminuted chicken diet without Benefiber (control diet). The study period was seven days. RESULTS: Of 116 children, 57 received the study diet and 59 received the control diet. Diarrhoea resolved in a greater number of children with the study than with the control diet (46/55 (84%) v 36/58 (62%); odds ratio 3.12, 95% CI 1.19 to 8.4). Survival analysis for the duration of diarrhoea also showed a reduced duration of diarrhoea in children receiving the study diet. There was also a trend in daily stool reduction in children receiving the study diet, significant on days 4-7. CONCLUSION: Results show that Benefiber supplemented comminuted chicken diet enhances recovery of children with persistent diarrhoea, indicating its therapeutic potential. 相似文献
