AIM: To test the hypothesis that duodenal colonization represents the final crucial step in the development of Helicobacter pylori related duodenal ulcer. METHODS: Patients with non-ulcer dyspepsia who had gastric colonization by H. pylori were included in the study. At baseline endoscopy, we evaluated the prevalence of duodenal colonization (culture, urease testing and histology), and cytotoxin-associated gene A status (polymerase chain reaction). No patients received eradication during 1 year follow-up. At this time, endoscopy was repeated and the incidence of duodenal ulcer was assessed. RESULTS: Among 181 patients completing follow-up, 53 (29%) had duodenal colonization: 72% of them were cytotoxin-associated gene A positive, versus 37% patients without duodenal colonization (P < 0.001). Duodenal ulcer developed in 12 (22.6%) patients with duodenal colonization and in two (1.6%) without duodenal colonization (odds ratio for duodenal ulcer: 6.29, 95% confidence intervals 2.44-17.45). The incidence of duodenal ulcer was similar among cytotoxin-associated gene A positive and cytotoxin-associated gene A negative subjects with duodenal colonization: 21.05% versus 26.6%. CONCLUSIONS: The assessment of duodenal colonization by H. pylori in patients with non-ulcer dyspepsia is strongly predictive for the subsequent development of duodenal ulcer and may help to stratify patients at risk for this disease.
Experience of surgical treatment of 73 patients with different postvagotomic syndromes was analyzed. The recurrent ulcers were seen most often -- in 54 (74.0%) patients. All the patients have undergone selective proximal vagotomy including isolated surgery in 19 patients and in combination with different drainage surgeries in 54 patients. High gastric secretion was the cause of recurrent ulcers in all the cases. Resection of the stomach was the most often reconstructive surgery -- 58 (79.5%) patients. Three (4.1%) patients died. It is concluded that postvagotomic syndromes are severe diseases of operated stomach with difficult treatment, further studies are necessary.
BACKGROUND: The effect of Helicobacter pylori in provoking or protecting against gastro-oesophageal reflux disease is unclear and studies have given conflicting results. Recent guidelines recommend H. pylori eradication in patients on long-term proton pump inhibitors. AIM: To ascertain the effect of H. pylori eradication on gastro-oesophageal reflux disease outcomes (reflux oesophagitis and heartburn) in patients with duodenal ulcer disease, and to ascertain the effect of H. pylori infection on reflux oesophagitis concerning heartburn, pH, severity, healing and relapse rates. METHODS: A systematic review of electronic databases was undertaken to September 2003. Experts in the field, pharmaceutical companies and journals were contacted about unpublished trials. Studies were reviewed according to predefined eligibility and quality criteria. Twenty-seven studies/trials were included in the systematic review. RESULTS: Study variation rather than therapy-influenced results in relation to the presence or absence of oesophagitis in patients with duodenal ulcer who underwent H. pylori eradication at 6-48 months follow-up. In patients with reflux oesophagitis no obvious differences were discovered in heartburn scores, 24-h pH values, healing and relapse rates between H. pylori-positive and -negative cases. CONCLUSION: There is no evidence to indicate that H. pylori eradication in duodenal ulcer disease provokes reflux oesophagitis or worsens heartburn; (ii) there are insufficient data to draw firm conclusions about the impact of H. pylori in patients with reflux oesophagitis.
