Chapter III Helicobacter pylori testing in dyspeptic patients suspected of peptic ulcer disease in primary care; development of a simple diagnostic scoring rule

چکیده
Objectives: To develop an easy applicable diagnostic scoring rule to determine the presence of peptic ulcers in dyspeptic patients in the primary care setting, and to evaluate whether Helicobacter pylori (H pylori) testing has added value to optimal history taking. Design: Cross-sectional study. Setting: Patients selected from general practitioner’s offices in the area of Utrecht, the Netherlands. Participants: 565 primary care patients consulting the general practitioner with dyspeptic complaints lasting at least two weeks. Main outcome measures: The presence or absence of peptic ulcer. Independent predictors of the presence of peptic ulcer as obtained from history taking and the added value of H pylori testing were quantified using multivariable logistic regression analyses. Results: A history of peptic ulcer, pain on an empty stomach and smoking were strong and independent diagnostic determinants of peptic ulcer disease with odds ratios of 5.5 (95% CI 2.6-11.8), 2.8 (95% CI 1.0-4.0) and 2.0 (95% CI 1.4-6.0), respectively. The ROC area of these determinants together was 0.71. Adding the H pylori test increased the ROC area to only 0.75. However, in a high-risk patient group, identified by means of a simple scoring rule based on history taking, the predictive value for the presence of peptic ulcer increased from 16% to 26% after a positive H pylori test. Conclusions: In the total group of dyspeptic patients in primary care H pylori testing has no value in addition to history taking in diagnosing peptic ulcer disease. In a subgroup of patients at high risk for having peptic ulcer disease, however, it might be useful to test-and-treat for H pylori infections. Hp diagnostic scoring rule 45

متن کاملHistological Changes In Gastric Biopsies From Helicobacter Pylori-Infected Patients With And Without Peptic Ulcer
Background and Objective: Long period risk of gastric carcinoma in people affected with chronic Helicobacter pylori gastritis is 5 times more than normal people. Perhaps histological changes due to helicobacter pylori infection could be used for screening people at risk of gastric carcinoma and peptic ulcer. Materials and Methods: This study has been carried out as a cross...

STUDY OBJECTIVE To assess the role of testing for Helicobacter pylori in the management of dyspeptic patients in primary care. DESIGN Selective review of literature frequently quoted to support use of H pylori testing. MAIN RESULTS Testing for H pylori and referral of only positive cases for endoscopy aims to reduce the number of "unnecessary" endoscopies. Patients with negative results may...

Helicobacter pylori, an important etiological agent in the development of gastritis, peptic ulcer and gastric carcinoma, can be detected by the enzyme-linked immunosorbent assay (ELISA). Our objectives were: (1) to evaluate the efficacy of a commercial ELISA kit (Pyloriset EIA-G III) in sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for ...

OBJECTIVES It has remained controversial how to manage patients who present with symptoms of dyspepsia. Should all dyspeptic patients undergo a radiological or endoscopic procedure to diagnose peptic ulcer, or would a serological test for Helicobacter pylori provide sufficient evidence to start all H. pylori-positive patients on empirical antibiotic therapy? METHODS The outcome of serological...
