Helicobacter pylori eradication in complicated peptic ulcer: Beneficial in most? Helicobacter pylori eradication therapy has a role in minimizing the complications of peptic ulcer disease, namely, bleeding, perforation, and obstruction. However, the precise role of H.

The mechanisms whereby Helicobacter pylori produces different pathological manifestations in the stomach and duodenum are not fully understood. Considering the geographic diversity in the prevalence of virulence factors of this microorganism and their association with the development of different diseases, the search for pathogenicity markers such as CagA and VacA alleles by molecular techniques has intensified. To investigate the presence of H.

Helicobacter pylori H. In recent years, an alarming increase in antimicrobial resistance and subsequently failing empiric H. Therefore, rapid and accurate determination of H. Traditionally, detection of H. Recent advances in diagnostics provide new tools, like real-time polymerase chain reaction PCR and line probe assays, to diagnose H. In the first part of this review, we will give an overview on currently available diagnostic methods for detection of H.

The discovery of Helicobacter pylori has already changed the natural history of peptic ulcer disease, with most patients being cured at their first presentation. Similarly, the incidence of gastric cancer and other diseases related to H. Isolation of the spiral intragastric bacterium H. We should consider such provocative scientific ideas as bridges to the future disease control. Epidemiologic studies have also provided convincing evidence that H.

Upper gastrointestinal UGI bleeding is the most frequently encountered complication of peptic ulcer disease. Therefore, testing for and diagnosing Hp infection are essential for every patient with UGI hemorrhage. The presence of the infection is usually underestimated in cases of bleeding peptic ulcers. A rapid urease test RUT , with or without histology, is usually the first test performed during endoscopy. If the initial diagnostic test is negative, a delayed 13 C-urea breath test UBT or serology should be performed. Once an infection is diagnosed, antibiotic treatment is advocated.

Deciding on whether the Helicobacter pylori test-and-treat strategy is an appropriate diagnostic—therapeutic approach for patients with dyspepsia invites a series of questions. The aim present article addresses the test-and-treat strategy and attempts to provide practical conclusions for the clinician who diagnoses and treats patients with dyspepsia. We focused mainly on data from randomized controlled trials RCTs , systematic reviews, meta-analyses, cost-effectiveness analyses, and decision analyses. Several prospective studies and decision analyses support the use of the test-and-treat strategy, although we must be cautious when extrapolating the results from one geographical area to another. Many factors determine whether this strategy is appropriate in each particular area. The test-and-treat strategy will cure most cases of underlying peptic ulcer disease, prevent most potential cases of gastroduodenal disease, and yield symptomatic benefit in a minority of patients with functional dyspepsia. Future studies should be able to stratify dyspeptic patients according to their likelihood of improving after treatment of infection by H.

Histological and rapid urease tests to detect H. We aimed to examine whether immunohistochemistry and real-time PCR can improve the sensitivity of these biopsies. We selected 52 histology-negative formalin-fixed paraffin-embedded biopsy specimens obtained during PUB episodes. Additional tests showed 10 were true negatives and 42 were false negatives. We also selected 17 histology-positive biopsy specimens obtained during PUB to use as controls. All controls were positive for H. Real-time PCR improves the detection of H.
