RESUMEN
Background: we assessed the prevalence, the related symptoms, and the endoscopic and histologic gastric features of celiac disease (CD) in patients with Helicobacter pylori (Hp).Methods: 450 dyspeptic patients were studied. Biopsies of gastric antrum and duodenum, CD serology, and total IgA were obtained. Histological findings were scored with the Marsh-Rostami criteria. Results: 411 (91.3%) patients were Hp positive. Duodenal histology was normal in 385 (85.6%) patients, 124 (27.5%) had duodenitis and 28 (6.2%) showed duodenal abnormalities (Marsh I-IIIc). Twenty three/28 (82.1%) patients with malabsorption pattern were also Hp positive. Serological analysis: 12 of 31 (38.7%) positive patients had abnormal histology (Marsh I,-IIIc). Nine out 450 patients were IgA deficient; none of them was serologically positive for CD. Conclusion: although a high prevalence of Hp infection was found in this study, the relationship between Hp infection and C D was similar to that reported in other geographic areas(AU)

BACKGROUND: Vitamin C in gastric juice and in vitro has been shown to inhibit the growth of Helicobacter pylori (H. pylori). AIMS: The purpose of this study was to investigate the effect of addition of vitamin C to eradication regimen on H. pylori eradication rate. PATIENTS: This randomised controlled clinical trial was conducted on 312 patients with H. pylori infection who had referred to the Taleghani Research Center of Gastroenterology and Liver Disease. METHODS: Patients were randomly divided into two groups. Group A patients (162 patients) received amoxicillin 1g and metronidazole 500 mg b.i.d., bismuth 240 mg b.i.d. and omeprazole 40 mg q.i.d. in two divided doses. Patients in group B (150 patients) received the same regimen plus 500 mg vitamin C per day. All patients received therapy for 2 weeks. Four weeks later all patients underwent urea breath test and results were compared. RESULTS: A total of 140 patients in group A and 141 in group B completed the study. On intention-to-treat analysis 48.8% of patients in group A in comparison to 78% in group B responded to eradication therapy and had negative urea breath test (p<0.0001). CONCLUSION: Addition of vitamin C to H. pylori treatment regimen of amoxicillin, metronidazole and bismuth can significantly increases H. pylori eradication rate.
