Helicobacter pylori infection in Burkina Faso: an enigma within an enigma.
2004
Background. In Burkina Faso, in contrast with high rates of Helicobacter pylori infection from an early age, the prevalence of H. pylori-associated diseases (ulcer and gastric cancer) is low. Aims. To look for the prevalence of H. pylori in healthy natives of Burkina Faso, both children and adults. Methods. We studied the prevalence of H. pylori infection in 258 healthy natives of Burkina Faso (70 children aged 6 months–15 years and 188 adults aged 16–65 years), using a serological screening (IgA and IgG H. pylori antibodies). All the studied subjects underwent a questionnaire regarding their life-style, socio-economic status, dietary habits and hygienic sanitary conditions. Data concerning…
Pepsinogen testing for evaluation of the success of Helicobacter pylori eradication at 4 weeks after completion of therapy.
2014
Background and objective: Pepsinogen levels in plasma are increased by inflammation in the gastric mucosa, including inflammation resulting from Helicobacter pylori infection. A decrease in pepsinogen II level has been suggested as a reliable marker to confirm the successful eradication of infection. The aim of our study was to evaluate the potential role of pepsinogens I and II, gastrin-17 and H. pylori antibodies in confirming successful eradication. Material and methods: Altogether 42 patients (25 women, 17 men), mean age 45 years (range 23–74), were enrolled. Pepsinogens I and II, gastrin-17 and H. pylori IgG antibodies were measured in plasma samples using an ELISA test (Biohit, Oyj., …
Helicobacter pylori infection in children.
2008
The review summarizes the articles published on Helicobacter pylori in children between April 2007 and March 2008. Evidence is emerging in different populations including developing countries that the prevalence of H. pylori is declining in all age groups. The reasons for this are unclear but it is unlikely that treatment of infection or improvement in socioeconomic conditions fully explains the decline. For the first time, differences in the inflammatory response between adults and children have been well characterized in a group of adults and children from Chile with similar levels of H. pylori infection. This study suggests that the reduced inflammatory response to H. pylori at a cellula…
Detection of Helicobacter pylori using PCR in dental plaque of patients with and without gastritis.
2010
Objectives: Helicobacter pylori (H. pylori) accounts for gastritis, peptic ulcer and is a probable cause of gastric cancer. Since its detection in the oral cavity, concerns have been raised about dental plaque as a reservoir for reinfection. The aim of this study was to detect the organism in the dental plaque and to determine the association, if any, between H. pylori gastritis and dental plaque contamination causing H. pylori. Study design: A polymerase chain reaction-based method was used for detection of H. pylori in clinical specimens. Supra and subgingival samples were collected from 67 patients with chronic periodontitis, 23 of whom were also suffering from gastritis. The data were a…
Helicobacter pylori infection does not affect the early rebleeding rate in patients with peptic ulcer bleeding after successful endoscopic hemostasis…
2003
Background and study aims Eradication of Helicobacter pylori infection can reduce the rebleeding rate of peptic ulcer bleeding in the long term. There are few data on the influence of H. pylori on the rebleeding rate in the acute phase of bleeding however. We therefore prospectively investigated the influence of H. pylori infection on the early rebleeding rate in patients who had undergone successful endoscopic hemostasis treatment for peptic ulcer bleeding. Patients and methods Between January 1996 and November 2000 all patients with peptic ulcer bleeding were evaluated consecutively. The diagnosis of H. pylori infection was made at index endoscopy, using histology and the rapid urease tes…
Pepsinogen Test for the Evaluation of Precancerous Changes in Gastric Mucosa: a Population-Based Study
2018
Aims: The aim of the study was to evaluate the rationale of blood pepsinogen (PG) testing in population based screening settings.Methods: Participants from a cross-sectional population-based study of cardiovascular risk factors in Latvia were invited to participate in the current study. Pepsinogen I and II were measured in blood samples taken during the initial study and at follow-up; upper gastrointestinal endoscopy was performed. There were three groups of patients: with moderately decreased (PG I< 70 ng/ml and PG I/PG II ratio < 3), with strongly decreased (PG I< 30 ng/ml and PG I/PG II ratio < 2), and with normal PG level. Biopsy with H. pylori detection was performed (updat…
Lack of significant differences between gastrointestinal tract microbial population structure of Helicobacter pylori-infected subjects before and 2 y…
2020
Background According to recent estimates 80% of Latvian population is infected with Helicobacter pylori thus their susceptibility to numerous gastric tract diseases is increased. The 1st line H. pylori eradication therapy includes treatment with clarithromycin in combination with amoxicillin or metronidazole and a proton pump inhibitor. However, potential adverse events caused by such therapies to microbiome are insufficiently studied. Objective This study aimed to evaluate the long-term effect of H. pylori eradication on human gastrointestinal tract (GIT) microbiome. Methods The assessment of H pylori eradication impact on GIT microbiome was done by analyzing 120 samples acquired from 60 s…
Molecular detection of Helicobacter pylori in oral samples from patients suffering digestive pathologies
2010
Objective: to determine the simultaneous presence of H. pylori in both the oral cavity and gastric mucosal in patients suffering digestive pathologies and to establish the possible association between the presence of H. pylori in the oral cavity and the gingivoperiodontal pathology. Study design: Patients with gastric symptoms (case group) and asymptomatic patients (control group) seen at the Gastroenterology Department of Dr. Julio C. Perrando Hospital (Resistencia, Argentina) were selected. Dental plaque and saliva samples from both groups were obtained. In the case group, gastric biopsy samples were also taken. H. pylori was detected in gastric biopsies by histological stains, and Polyme…
Sociodemographic, Lifestyle and Medical Factors Associated with Helicobacter Pylori Infection
2020
Background and Aims: The prevalence of Helicobacter pylori (H. pylori) infection is higher in developing countries and is often linked to lower socioeconomic status. Few studies have investigated the association between H. pylori and individual level characteristics in Europe, where several countries have a high prevalence of H. pylori infection. The study aimed to identify risk factors for H. pylori infection among adults in a large clinical trial in Latvia.
 Methods: 1,855 participants (40-64 years) of the “Multicenter randomized study of H. pylori eradication and pepsinogen testing for prevention of gastric cancer mortality” (GISTAR study) in Latvia tested for H. pylori IgG antibodi…
Effect of intravenous application of esomeprazole 40???mg versus pantoprazole 40???mg on 24-hour intragastric pH in healthy adults
2007
BACKGROUND: It has been demonstrated that therapy with proton pump inhibitors reduces recurrence of bleeding following initial endoscopic treatment of bleeding peptic ulcers. AIM: This study compared the effects of esomeprazole 40 mg and pantoprazole 40 mg on intragastric acid control. Both substances were administered intravenously as 15-min infusion and as bolus injection. METHODS: Healthy men and women volunteers were enrolled in this single-center, open, randomized, three-way crossover study. After administration of esomeprazole 40 mg and pantoprazole 40 mg intravenously as 15-min infusion, and pantoprazole 40 mg intravenously as bolus injection, continuous 24-h intragastric pH monitori…
