BACKGROUND Increasing resistance to clarithromycin and nitroimidazole is the main cause of failure in the Helicobacter pylori eradication. The ideal retreatment regimen remains unclear, especially in developing countries, where the infection presents high prevalence and resistance to antibiotics. The study aimed at determining the efficacy, compliance and adverse effects of a regimen that inclu...

BACKGROUND/AIMS In this study we aimed to investigate the sensitivity and specificity of Narrow Band Imaging (NBI) in H. pylori gastritis and compare them with those of rapid urease test and urea breath test. MATERIALS AND METHODS A hundred sixty-five children who admitted to Uludag University Pediatric Gastroenterology Unit between October 2009-March 2011 with upper gastrointestinal symptoms...

Helicobacter pylori is one of the most frequently occurring and persistent bacterial infections worldwide. H. pylori bacteria are associated with peptic ulcer disease, mucosaassociated lymphoid tissue lymphoma, and gastric cancer. Various diagnostic methods are used to detect H. pylori infection. However, only highly accurate tests with 90% sensitivity and 90% specificity should be used in clin...

Evaluation of Polymerase Chain Reaction (PCR) Using Tissue Sample from Rapid Urease Test Kit (CLO® Test) in the Detection of Helicobacter Pylori.: Comparison with PCR from Gastric Biopsy, Rapid Urease Test, and Histologic Result Sang Bae Kim, Woo Chul Chung, Eun Jung Kim, Hae Jung Sung, Yang Woon Lee, You Suk Oh, Chang Nyol Paik, Kang-Moon Lee Department of Internal Medicine, College of Medicin...

Gastric biopsy specimens from 283 patients with ulcer and non-ulcer dyspepsia attending five gastroenterology clinics in the northern region of the United Arab Emirates (UAE) were tested by the agar gel test (n = 115) or the ultra-rapid endoscopy room test (n = 168) for the presence of Helicobacter pylori urease. Results were compared with a histological technique using the Romanowsky type (Dif...

The main purpose of the study is to determine resistance pattern of bacterial isolates to selected antibiotics among 88 dyspeptic patients in Iran. Frequency of infection among these patients have been evaluated among dyspeptic patients old (45 boys and 43 girls, aged 5-18 years) from 2016 to 2017.Eighty-eight patients with gastroduodenal disorders were included in the study. Urease test modifi...

Among the methods developed to detect H. pylori infection, determining the gold standard remains debatable, especially for epidemiological studies. Due to the decreasing sensitivity of direct diagnostic tests (histopathology and/or immunohistochemistry [IHC], rapid urease test [RUT], and culture), several indirect tests, including antibody-based tests (serology and urine test), urea breath test...

BACKGROUND Reliable non-invasive methods for detection of Helicobacter pylori infection are required to investigate the incidence, transmission, and clearance of infection in childhood. AIM To evaluate a new monoclonal enzyme immunoassay (EIA) (FemtoLab H pylori Cnx) for detection of H pylori antigen in stool in a large cohort of children compared with invasive diagnostic methods and the (13)...

brucellosis is one of the most common zoonotic diseases in iran and human brucellosis is endemic in all parts of the country. growth of brucella is slow and blood culture of these bacteria by use of classical methods is time-consuming. furthermore, in endemic area culture is required for definitive diagnosis. in the present study, direct urease test and acridine orange staining were tried on th...
