CONTEXT The correct diagnosis and effective treatment of Helicobacter pylori gastric infection are essential in controlling this infection. OBJECTIVE To compare the diagnostic value of three tests based in endoscopic gastric biopsies histopathological evaluation with hematoxylin-eosin (H-E) staining, urease rapid test and microbiological culture for detecting Helicobacter pylori active infect...

pies remains to be established. Eventually, we recommended a prolonged therapy including PPI (40 mg of omeprazole three times daily) and amoxicillin (1 g three times daily) for 4 weeks, which turned out to be successful, as shown by negative [C]urea breath test, rapid urease test, histopathology, culture and molecular genetic testing 6 weeks after therapy. Multiresistant clinical H. pylori isol...

Aim. To compare 10-day standard triple therapy versus sequential therapy as first-line treatment in patients infected with H. pylori. Methods. One hundred H. pylori positive patients (diagnosed by rapid urease test and histology), with average age of 47.2, M/F = 28/72, were randomized to receive either standard triple treatment (TT) as follows: lansoprazole 30 mg, clarithromycin 500 mg, and amo...

Helicobacter pylori (HP)(1) management (including diagnosis and therapy) has been exhaustively reviewed in several reports. These reports are unanimous in that several clinical conditions seriously hamper the diagnostic value of two HP tests: 13 C-Urea Breath Test (UBT) and Stool Antigen test (SAT), because of the false-negative results frequently (up to 40%) obtained in these conditions. Basic...

objective: to investigate the presence of helicobacter pylori in sinonasal mucosa of patients with chronic sinusitis design: a prospective case-control study materials and methods: mucosal specimens were collected from the mid-third middle meatus and lateral side of mid-cornea. h. pylori has been investigated using pcr after dna extraction and urease test. results: h. pylori was not found in an...

Several techniques have been proposed to diagnose H. pylori infection based either on the direct or indirect detection of the bacteria. [table: see text] The current direct methods are performed on biopsy specimens obtained at endoscopy. Histological examination must always be performed because in addition to H. pylori detection it allows observation of the lesions present. Culture, while more ...

Helicobacter pylori has been involved in the pathogenesis of chronic idiopathic urticaria (CIU) in patients suffering both CIU and H. pylori infection. We selected 49 patients with 13C urea breath test positive, long-lasting CIU and H. pylori infection; 20 remained symptomatic, had positive urease test or H. pylori histologic identification in gastric biopsy material and accepted to participate...

Helicobacter pylori-eliminating effects of FEMY-R7, composed of fucoidan and evening primrose extract, were investigated in mice and humans. Male C57BL/6 mice were infected with the bacteria by intragastric inoculation (1×10(9) CFU/mouse) 3 times at 2-day intervals, and simultaneously, orally treated twice a day with 10 or 100 mg/kg FEMY-R7 for 2 weeks. In Campylobcter-like organism-detection t...

OBJECTIVES The objective of this study was to assess the outcome of antimicrobial susceptibility-guided therapies in Helicobacter pylori-infected individuals who had undergone unsuccessful prior eradication treatments. METHODS From October 2004 to December 2013, 481 H. pylori-positive patients with prior unsuccessful eradication treatments were administered susceptibility-guided salvage eradi...

Helicobacter pylori infects nearly 50% of the world's population. This microorganism is accepted as the most important agent of gastritis and as a risk factor for peptic ulcer disease and gastric adenocarcinoma. Currently many diagnostic methods exist for detecting H. pylori, however they all have limitations, thus it is recommend a combination of at least two methods. The aim of this study was...
