    Notes: Background: Helicobacter pylori infection of the antral mucosa is responsible for an increase in basal and stimulated serum gastrin. In the present study we have investigated whether gastritis induced by H. pylori is responsible for abnormalities in the processing of gastrin in dyspeptic patients.Methods: Basal serum gastrin was measured by radioimmunoassay before, 5 weeks, and 1 year after anti-H. pylori therapy in 73 H. pylori positive functional dyspeptic patients. Three region-specific antisera were used, specific for the biologically active carboxy-terminal part, the biologically inactive aminoterminal part of gastrin 1–17, and for the nonsulphated tyrosyl residue in gastrin 1–17.Results: Basal serum gastrin levels were markedly (P 〈 0.01) decreased 5 weeks and 1 year after successful eradication of H. pylori (n= 39) but not in the patients in whom treatment failed (n= 34). A decline of gastrin was observed for each of the three radioimmunoassays. Conclusion: The decrease of serum gastrin levels in all three radioimmunoassays after a successful eradication of H. pylori does not point to major changes in the processing of gastrin. These results suggest that G-cells in the antral mucosa are not functionally affected by the inflammation.

    Notes: Thirty-three dyspeptic patients with colonization of Helicobacter pylorl in the gastric antrum were treated with tripotassium dicitrate bismuthate 120 mg q.d.s. for 28 days and metronidazole 250 mg q.d.s for 10 days starting on day 19. Five weeks after cessation of this treatment regimen H. pylori was eradicated in 23 patients. In 8 of the remaining 10 patients, H. pylori had become resistant to metronidazole. In this study resistance was significantly associated with smoking habits, but not with age, bacterial load, gastritis score or alcohol consumption.

    Anxiety, depression and psychotropic medication use in patients with persistent upper and lower gastrointestinal symptoms (2005)

    Notes: Background:  Limited information is available about anxiety, depression and psychotropic medication use in patients referred for gastrointestinal endoscopy.Aim:  To determine anxiety and depression and its association with endoscopic findings in a representative sample of patients with persistent gastrointestinal symptoms prior to endoscopy.Methods:  Patients referred to the hospital for endoscopy between February 2002 and February 2004 were asked to score anxiety and depression on the Hospital Anxiety and Depression Scale 2 weeks prior to endoscopy. Information about endoscopic diagnoses was obtained from medical files.Results:  A total of 1298 subjects was studied (600 upper gastrointestinal endoscopies and 698 lower gastrointestinal endoscopies). Patients referred for upper gastrointestinal endoscopy used most psychotropic agents (24%; odds ratio = 3.1; 95% confidence interval = 2.3–4.2), especially patients with an organic abnormality when compared with patients without an organic abnormality (42% versus 8%; odds ratio = 8.6; 95% confidence interval = 5.4–14.0). Patients with colonic polyps were more anxious (odds ratio = 1.7; 95% confidence interval = 1.0–2.9) and depressed (odds ratio = 1.8; 95% confidence interval = 1.1–3.1) than other patients referred for lower gastrointestinal endoscopy.Conclusions:  There is no difference in anxiety nor depression between patients with and without organic abnormalities at endoscopy. Patients with colonic polyps are more anxious and depressed than other patients referred for lower gastrointestinal endoscopy. Psychotropic medication use is highest among patients with an organic abnormality in the proximal gastrointestinal tract.

    Notes: Background : Little is known about the variation in health-related quality of life among patients with different presentations of gastrointestinal symptoms.Aim : To study the association between health-related quality of life and presentations of gastrointestinal symptoms.Methods : Health-related quality of life and demographic information was obtained from 873 patients referred to the hospital for endoscopy, using a questionnaire.Results : A total of 436 patients (50%) reported predominantly upper gastrointestinal symptoms, 344 (39%) predominantly lower symptoms, and 93 (11%) patients reported both upper and lower symptoms. Patients with mild, moderate and severe symptoms, reported mean scores on a 100-point visual analogue scale (95% CI) of 90 (79–100), 75 (64–86) and 64 (53–76), respectively (P 〈 0.001). Mean visual analogue scale scores (95% CI) almost linearly declined from 81 (77–85) to 49 (46–52) for those with one to those with more than eight symptoms. Patients who reported upper gastrointestinal symptoms and in particular epigastric pain, bloating and vomiting had significantly impaired health status in comparison to patients without these symptoms (P 〈 0.05).Conclusions : Severity of gastrointestinal symptoms is the most important factor in affecting health status, followed by the numbers and type of gastrointestinal symptoms.
