Fifty patients with GERD were randomly assigned to receive dexrabeprazole 10 mg or rabeprazole 20 mg once daily. Efficacy was assessed by evaluating improvement in visual analog scale （VAS） scores of heart-burn and regurgitation and safety was assessed by recording incidence of any adverse drug reactions. Laboratory investigations and upper gastro-intestinal endoscopy was conducted at baseline and after 28 d of therapy.RESULTS： A total of 50 patients （n = 25 in dexrabeprazole group and rabeprazole group each） completed the study. There were no significant differences in the baseline characteristics between the two groups. The VAS score （mean 4. SD） of heartburn and regurgitation in dexrabeprazole （64.8±5.1 and 64 ± 8.1, respectively） and rabeprazole （64.4 ± 8.7 and 57.6 ± 9.7, respectively） groups significantly reduced （P 〈 0.0001） to 30 ± 11.5, 24 ± 10 and 32 ± 9.5, 29.2±11.9, respectively on d 28. A significantly higher （P = 0.002） proportion of patients showed ≥ 50% improvement in regurgitation with dexrabeprazole 10 mg （96%） compared to rabeprazole 20 mg （60%）. Onset of symptom improvement was significantly earlier with dexrabeprazole than with rabeprazole （1.8 ± 0.8 d vs 2.6 ± 1.4 d; P 〈0.05）. The incidences of esophagitis in the dexrabeprazole group and rabeprazole group before therapy were 84% and 92%, respectively （P = 0.38）. The incidence of improvement/healing of esophagitis after therapy was more （P = 0,036） in the dexrabeprazole group （95.2%） compared to the rabeprazole group （65.2%）. No adverse drug reaction was seen in either group.CONCLUSION： In the treatment of GERD, efficacy of dexrabeprazole 10 mg is better than rabeprazole 20 mg, with regards to improvement/healing of endoscopic lesions and relief from symptoms of regurgitation.展开更多

The aim of this study therefore was to prospectively evaluate the histological findings and the impact of Hpyloriinfection on a group of symptomatic patients with NERD. METHODS:Fifty consecutive patients were prospectively evaluated for symptoms compatible with GORD.In all cases, routine endoscopy and lugol directed biopsies were performed and assessed histologically in a blinded manner. RESULTS:The overall prevalence of Hpyloriinfection was 70%.Twenty-nine patients out of 50 (58%) were NERD patients.No statistical significance was observed between the H pyloristatus and NERD.The remaining 21 (42%) were diagnosed as follows:13 (26%),6 (12%),2(4%) with esophagitis grade A,B and C respectively.A statistically significant correlation was observed between the Hpylori+ and esophagitis grade A,as well as between Hpylori-and grade B.Biopsies from 2 patients were not included because of insufficient materials.Histologically,a basal zone hyperplasia was found in 47 (97.91%) patients,alterations of glycogen content in 47 (97.91%),papillae elongation in 33 (68.75%), blood vessels dilatation in 35(72.91%),chronic inflammation in 21 (43.75%),infiltration with eosinophils,neutophils and T-lymphocytes in 4 (8.33%),6 (12.5%) and 39 (81.25%) respectively.No correlation was observed between the Hpyloristatus and the histological parameters studied either in NERD or GERD. CONCLUSION:Histological assessment can not differentiate symptomatic patients with erosive versus non-erosive reflux disease.Moreover,Hpyloriinfection may not act as an important factor in patients with NERD.展开更多

This article outlines some of the interesting research findings. It comprises three parts. The first part dealt with recent data on the changing epidemiology of GERD in Asia.The second part summarized published studies on the relationship between GERD and Helicobacter pylori, relevant to the Asia-Pacific region.

METHODS： We selected 198 asthmatics with gastro- esophageal reflux diagnosed by 24-h esophageal pH moni- toring to receive Ome 20 mg twice daily and Dom 10 mg three times daily or placebo for 16 wk （1：1 double-blind randomization）. Spirometry was done at baseline and after 16 wk of treatment. The primary outcome measures were： mean daily daytime and nighttime asthma symptom scores. Mean daily reflux symptom scores, albuterol use as rescue medication （number of puffs）, daytime and nighttime peak expiratory flow rate （PEFR）, postbronchodilator forced expiratory volume in 1 second （FEVl） and postbronchodilator forced vital capacity （FVC） were secondary outcome measures. RESULTS： Comparison of mean change from baseline between antireflux therapy and placebo groups revealed significant reduction in daytime asthma symptom score （17.4% vs 8.9 %）, nighttime asthma symptom score （19.6% vs 5.4%）, reflux symptom score （8.7% vs 1.6%） and rescue medication use （23.2% vs 3.1%） after antireflux therapy compared to mean change in placebo group （P 〈 0.001）. There was significant improvement in morning PEFR （7.9% vs 0.2%）, evening PEFR （9.8% vs 0.5%）, FEW （11.1% vs 3.78%） and FVC （9.3%vs 1.52%） in the antireflux therapy group compared to placebo on comparng the mean change from baseline after 16 wk （P 〈 0.01） CONCLUSION： Combined therapy with Ome and Dom in adult asthmatics with gastroesophageal reflux may be beneficial by reducing asthma symptoms, rescuing medi- cation use, and improving pulmonary function.展开更多

METHODS:627 patients in the referral database received esophageal manometry and ambulatory 24-hour pH monitoring.Study data included LES resting pressure(LESP), overall LES length(OL)and abdominal length(AL),total vector volume(TVV)and intrabdominal vector volume(IVV). RESULTS:In cases where LESP,TVV or IVV were all below normal,there was an 81.4%probability of a positive DeMeester score.In cases where all three were normal, there was an 86.9%probability that the DeMeester score would be negative.Receiver-operating characteristics(ROC) for LESP,TVV and IVV were nearly identical and indicated no useful cut-off values.Logistic regression demonstrated that LESP and IVV had the strongest association with a positive DeMeester score;however,the regression formula was only 76.1%accurate. CONCLUSION:While the indices based on TVV,IVV and LESP are more sensitive and specific,respectively,than any single measurement,the measurement of vector volumes does not add significantly to the diagnosis of GERD.展开更多
