ABSTRACT

Objective To investigate the correlation of the infection of helicobacter pylori (Hp) and nocturnal acid breakthrough (NAB) for patients with gastroesophageal reflux disease (GERD). Methods Patients with GERD who were admitted to our hospital from September 2012 to May 2013 were selected. Hp infection of the patients was tested via rapid urease tests of biopsy of gastric antrum and 14C-urea breath tests. 90 patients with GERD who were tested HP positive were randomly assigned to control group and observation group by digital method, with 45 in each group. The observation group received HP eradication, while the control group was orally administered pantoprazole sodium. Reflux diagnosis questionnaire (RDQ) scores, incidence of NAB and ratio of pH lower than 4.0 from 22 h at night till 8 h next day in the two groups before and after the treatment were compared. Results The incidence rate of NAB in observation group was 62.2%, significantly higher than that of 35.6% in control group, and the difference was statistically significant (P<0.05);There was no significant difference of RDQ scores between the two groups before the treatment (P>0.05); After the treatment, RDQ scores in observation group were (12.43 ±3.79)scores, significantly higher than that of (9.21±2.93) scores in control group, and the difference was statistically significant (P<0.05). Hp infection was positively correlated with NAB(r=0.812, P<0.05). Conclusion Hp infection has a certain effect on reducing the incidence of NAB and shows a significant protective effect on the occurrence and development of GERD.

ABSTRACT

Objective To assess the incidence of noctu rnal acid breakthrough(NAB) and its' relationship with Helicobacter pylori(H. pylori) infection in patients with duodenal ulcer. Methods Forty duodenal ulcer patients were randomly allocated in to five groups. Patients were treated by intravenous injection of omeprazole 40 mg twice daily(group 1), once daily(group 2), omeprazole 20 mg twice daily oral ly(group 3), omeprazole 20 mg once daily orally(group 4), and intravenous inject ion of cimetidine 600 mg twice daily (group 5) all for 5 days. Intragastric pH o ver 24 hours was consecutively recorded on the fifth day for each patient. Results The mean intragastric pH, median intragastric pH, nocturn al mean pH and nocturnal median pH in group 1(6.9?0.7,7.3?0.8,6.8?0.9,7.1? 0 .7) were significantly higher than those of group 2 (5.3?1.6,5.6?1.7,4.9?1. 5,4.3?1.7),group 4(4.8?0.7,4.8?1.0,4.7?0.8,4.5?0.8), and group 5(4.4?2.4 ,4.5?2.5,4.6?2.7,4.3?2.1), but not higher than group 3(6.2?0.7,6.3?0.8,6. 4?1.1,6.4?0.8). High intragastric pH was produced in all five groups. The frac tion time of pH below 4.0 in group 1(3.1%) and group 3(4.5%) were significantly fewer than that in the other three groups(group 2,27.8%; group 4, (32.4)%, and group 5,48.2%) respectively. NAB occurred in 1 patient from two omeprazole twice dai ly groups(6.3 %, group 1 and 3) and in 9 patients from two omeprazole once daily groups((56.3 %,) group 2 and 4,P

ABSTRACT

Objective To assess the incidence and management of nocturnal acid breakthrough (NAB). Methods Forty patients with duodenal ulcer confirmed by gastroscopy were randomly divided into five groups, eight patients in each group. Patients were treated by the following strategies for a course of 5 days: group A (omeprazole 20 mg per day orally in the morning), group B (omeprazole 20 mg twice a day orally in the morning and at 4 p.m), group C (intravenous injection of omeprazole 40 mg twice a day in the morning and at 4 p.m), group D (omeprazole 20 mg per day orally in the morning plus ranitidine 150 mg at bed time) and group E (omeprazole 20 mg twice a day orally in the morming and at 4 p.m plus ranitidine 150 mg at bed time) respectively. Intragastric pH over 24 hours was recorded on the morning of the fifth day for each patient. Results In comparison with that in group A, intragastric pH was higher in the other four groups. The mean intragastric pH and mean nocturnal pH each in group B (6.2?0.7, 6.4?1.1), group C (6.9?0.7, 6.8?0.9), group D (6.0?0.7, 5.9?0.7) and group E (5.8?0.5, 6.1?0.5) were significantly higher than those in group A (4.8?0.7, 4.7?0.8, P
