Filter by:Fuzheng Nizeng Formula (FZNZ) is derived from the classic formula Liujunzi Decoction. Former pilot study found that FZNZ promoted the recovery of gastric atrophy and relieve the relative symptoms. This study is to evaluate its efficacy for chronic atrophic gastritis with low-grade intraepithelial neoplasia, compared with positive control Molduodan granule.
Despite declining incidence rates, gastric cancer (GC) ranks the fourth leading cause of cancer-related mortality and the fifth most common cancer worldwide, with the highest incidence reported in Eastern Asia. The 5-year overall survival rate of early GC exceeds 90%, which was well above advanced GC. Most intestinal-type GCs follow the Correa cascade-inflammation,atrophy, intestinal metaplasia (IM), dysplasia and subsequent carcinoma. The presence of gastric mucosal atrophy and intestinal metaplasia are important risk factors for GC. The purpose of this study was to investigate the incidence of GC attributed to atrophic gastritis in a region with high incidence of GC.
This study aims at evaluating efficacy and safety of Vonorazon and amoxicillin dual therapy versus bismuth-containing quadruple Therapy(bismuth#esomeprazole#tetracycline and furazolidone) in H. pylori rescue therapy. It is hypothesized that Vonorazon and amoxicillin dual therapy is non-inferior to bismuth-containing quadruple Therapy. Patients with confirmed failure of H. pylori eradication will be randomized to one of the treatments described above. At week 6 follow-up visits, a urea breath test#rapid urease test or helicobacter pylori stool antigen test will be performed to confirm eradication.
Color change is a useful marker for the endoscopic identification of chronic atrophic gastritis (CAG) and gastric cancer (GC). Several histopathological studies have suggested a correlation between certain gastrointestinal lesions and intramucosal vascularity. The aim of this study is to investigate the association between the color and mucosal microvascular density of CAG and early GC using linked color imaging (LCI). In this study, Lesions diagnosed as CAG and early GC will be observed using LCI. In each image, the color values of atrophic and non-atrophic mucosa, as well as cancerous and non-cancerous mucosa, will be quantified using the International Commission on Illumination 1976 (L∗, a∗, b∗) color space. Histological microvascular density in biopsy or resected specimens will be evaluated using CD31 immunostaining. Color differences at the atrophic border and cancerous border, defined as Euclidean distances of color values between the atrophic and non-atrophic mucosa, as well as cancerous and non-cancerous mucosa, will be calculated according to mucosal microvascular density.
This study is to evaluate the efficacy and safety of DA-5219 in patients with acute or chronic gastritis
Grading endoscopic atrophy according to the Kimura-Takemoto classification can assess the risk of gastric neoplasia development. However, the false negative rate of chronic atrophic gastritis is high due to the varying diagnostic standardization and diagnostic experience and levels of endoscopists. Therefore, this study aims to develop an AI model to identify the Kimura-Takemoto classification.
Helicobacter pylori infection rate is decreasing in younger population; however, biennial gastroscopy is still recommended for all Koreans aged between 40 and 75 years. This study aimed to validate blood tests for gastric cancer screening according to the infection status of H. pylori (naive, current, and past infection).
The study is researching an experimental drug called dupilumab. The study is focused on participants with active eosinophilic gastritis (EoG) with or without eosinophilic duodenitis (EoD). Participants with EoD only are not eligible for enrollment. EoG and EoD are uncommon, persistent, allergic/immune diseases in which eosinophils (a type of white blood cell) gather in large numbers in the stomach and small intestine and cause inflammation and damage. The aim of the study is to evaluate the effect of dupilumab on relieving EoG (with or without EoD) symptoms and reducing inflammation in the stomach and, if applicable, small intestine in adults and adolescents aged 12 years and older, compared to placebo. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug - How much study drug is in your blood at different times - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects)
This research will be conducted nationwide in patients with autoimmune gastritis, focusing on their clinical characteristics, possible risk factors, and multi-omics analysis. Changes in gastrointestinal microbiota, host and microbial metabolism, gene transcription and biomarkers of autoimmune gastritis will be explored to provide evidence for further precise therapy of the disease.
This prospective multicenter study investigates the added benefit of incisura biopsy to correct identification of patients with high-risk chronic gastritis (OLGA stages III-IV). It compares a biopsy protocol with and without a single incisura biopsy in a non-inferiority design.
