BACKGROUND The 13C urea breath test (13C-UBT) is the gold standard for detecting Helicobacter pylori infection. H. pylori pathogenesis in patients with hepatitis B virus (HBV) and related diseases remains obscure. We used 13C-UBT to detect H. pylori infection in patients with chronic HBV infection, HBV-related cirrhosis, HBV-related hepatic carcinoma, and other chronic hepatic diseases. METHO...

The present study was designed to explore the existence of oral Helicobacter pylori (H. pylori), its relationship in the oral cavity to the success rate of eradication of the gastric H. pylori infection, and to determine if the mouthwash solution contained lysine (0.4%) and glycerol monolaurate (0.2%) (LGM) could eliminate oral H. pylori, as well as using the saliva H. pylori culture to confirm...

OBJECTIVES To compare the sensitivity and specificity of C[14] urea breath test with histopathological findings in biopsies obtained through endoscopy. METHODS In this cross-sectional study, conducted at the Medical Faculty Ankara University, Ankara, Turkey between January and October 2009, 100 patients aged 65 and above who fulfilled the criteria for inclusion were enrolled. Oesophago-gastro...

CONTEXT The standard doses of (13)C-urea in (13)C-urea breath test is 75 mg. OBJECTIVE To assess the diagnostic accuracy of (13)C-urea breath test containing 25 mg of (13)C-urea comparing with the standard doses of 75 mg in the diagnosis of Helicobacter pylori infection. METHODS Two hundred seventy adult patients (96 males, 174 females, median age 41 years) performed the standard (13)C-urea...

OBJECTIVE Reinfection rate of Helicobacter pylori after successful eradication is low in developed countries. This study was performed to determine the reinfection rate of H. pylori during a follow up period of 12 months in Iranian children. METHODS In this prospective study, children with H. pylori infection were treated with triple omeprazole based regimen. Patients with negative (13)C urea...

Helicobacter pylori has been recently detected in the oral cavity and oropharynx. However, the role it plays in oral and oropharyngeal pathogenesis remains unclear. The virulence of H. pylori strains can be distinguished according to the virulence factors genes carried. Our research has been focused on realtime PCR analysis of cagA and vacA genes of H. py...

BACKGROUND Helicobacter pylori is implicated as the causative agent for most duodenal and gastric ulcers. Invasive (endoscopy and biopsy) and noninvasive (serology, breath test) methods are currently available for definitive diagnosis of infectious peptic ulcer disease. METHODS Twenty-six patients with chronic gastritis symptoms underwent upper endoscopy, biopsy, rapid urease test, and [14C]u...

BACKGROUND Previous studies have demonstrated a higher prevalence of Helicobacter pylori (H. pylori) infection in patients with Parkinson's disease (PD) compared to controls. H. pylori infection affects levodopa absorption and its eradication significantly improves clinical response to levodopa. Here, we studied the prevalence of H. pylori infection and its eradication effects among our PD pati...

BACKGROUND Helicobacter pylori (H. pylori) is one of the most common bacterial infections in humans. There is a risk factor for gastric or duodenal ulcers, gastric cancer and MALT (Mucosa Associated Lymphoid Tissue)-Lymphomas. There are several invasive and non-invasive methods available for the diagnosis of H. pylori. The (13)C-urea breath test is a non-invasive method recommended for monitori...

Helicobacter pylori (H. pylori) infections affect roughly one-half of the world’s population. Although many standard regimens, including triple-drug therapy, eradicate H. pylori, success rate and efficacy have been declining due to associated side effects symptom severity. The addition probiotics a regimen can considerably increase eradication rates. objective is find probiotic Lactobacillus re...
