Comparison of 24-h control of gastric acidity by three different dosages of pantoprazole in patients with duodenal ulcer

1998

Background It is now clear that the extent to which gastric acid secretion must be suppressed varies with the clinical condition being treated. Aim To assess the 24-h control of gastric acidity and the individual response variability of three different doses of pantoprazole. Methods Sixty-four duodenal ulcer patients were recruited for this prospective, randomized, multicentre, double-blind, parallel-group study. They were subdivided into three well-matched groups treated with 20 mg o.m., 40 mg o.m. and 40 mg b.d. of pantoprazole, respectively. Endoscopy and intragastric pH monitoring were performed in each patient before and after 14 days of treatment. Results Fifty-five patients were elig…

66  In vitro comparison of six raw materials on gastric ecosystem activity and acidity

2021

International audience; The great biochemical variability of the raw materials used in horse feeds can induce changes in gastric fermentation, and therefore affect gastric health through the resulting acidity of the bacterial end products. This in vitro trial compared the effect of 6 raw materials (BA: barley; WB: wheat bran; OA: oats; SM: sunflower meal; SB: sugar beet pulp; AL: alfalfa – Table 1) commonly used in horse feeds on gastric bacterial fermentation and buffering capacity. In 3 horses fed a mixture of the 6 raw materials 3h before sampling, gastric chyme was collected via a nasogastric tube and mixed. Bottles containing 1mL of the mixed gastric chymes, 50mL dilution medium and 1.…

Regression of primary low-grade gastric mucosa-associated lymphoma by eradication of Helicobacter pylori infection: case report

2004

Objective: the Authors report their experience in diagnosis and treatment of one case of primary low-grade gastric lymphoma of mucosa associated lymphoid tissue (MALT); recent international literature review. Experimental Design: complete clinical report. Diagnostic, clinical and prognostic indication, evaluation of effectiveness of eradication therapy and short follow-up. Setting: Operative Unit of General and Thoracic Surgery. University "Paolo Giaccotie" of Palermo. Intervention: treatment of H. Pylori infection (lansoprazole, amoxicillin and metronidazole twice a day for 14 days; after that, lansoprazole for another 4 weeks), according to international guide-lines. Results: H. Pylori wa…

In vivo measurement of gastric fluid volume in anesthetized dogs

2020

Abstract The drug solubility is critical for the Biopharmaceutics Classification System (BCS), yet the criteria for solubility have not been precisely defined for dogs. In particular, the gastric fluid volume (GFV) of dogs which is used to measure the solubility has not been quantified in vivo. The aim of the work is to measure the GFV using magnetic resonance imaging (MRI) from 12 Beagle dogs weighing 9–12 kg (6 male and 6 female). We found that the average GFV within this weight range was 24.0 ± 4.2 mL. The result can be used for the BCS studies of canine drugs and also serves as a reference for other species.

Value of gastrin-17 in detecting antral atrophy.

2011

Decreased plasma gastrin-17 (G-17), particularly after protein stimulation, is indicative of atrophy in the antral stomach mucosa. Available data on the value of this biomarker is inconclusive. Our study was aimed to evaluate the performance of the G-17 test in Caucasian and Asian patients for antral atrophy evaluation either in fasting state or after protein stimulation.241 dyspeptic patients aged 55 and above from Latvia (125), Lithuania (76) and Taiwan (40) were enrolled. G-17 levels were detected in plasma samples obtained either during fasting or after a protein-rich test meal. Levels1 pmol/L at fast and5 pmol/L after stimulation were considered indicative of atrophy.The sensitivity of…

Main RecommendationsPatients with chronic atrophic gastritis or intestinal metaplasia (IM) are at risk for gastric adenocarcinoma. This underscores the importance of diagnosis and risk stratification for these patients. High definition endoscopy with chromoendoscopy (CE) is better than high definition white-light endoscopy alone for this purpose. Virtual CE can guide biopsies for staging atrophic and metaplastic changes and can target neoplastic lesions. Biopsies should be taken from at least two topographic sites (antrum and corpus) and labelled in two separate vials. For patients with mild to moderate atrophy restricted to the antrum there is no evidence to recommend surveillance. In pati…

Claudin-18 gene structure, regulation, and expression is evolutionary conserved in mammals

2011

Claudin-18 isoform 2 (CLDN18.2) is one of the few members of the human claudin family of tight junction molecules with strict restriction to one cell lineage. The objective of the current study was to compare molecular structure and tissue distribution of this gastrocyte specific molecule in mammals. We show here that the CLDN18.2 protein sequence is highly conserved, in particular with regard to functionally relevant domains in mouse, rat, rabbit, dog, monkey and human and also in lizards. Moreover, promoter regions of orthologs are highly homologous, including the binding site of the transcription factor cyclic AMP-responsive element binding protein (CREB), which is known to regulate acti…
