Objectives: Antral gastritis is frequent in alcoholics. The role of H. pylori in the pathogenesis of gastritis in these patients is not well known. The aim of our study was to study the role of H. pylori and cirrhosis in the pathogenesis of antral gastritis in alcoholic patients.
Methods: Seventy-nine patients were included in the study. All underwent upper gastrointestinal tract endoscopy with antral biopsies, independently of the presence of abdominal pain, and had serological examination for H. pylori antibodies.
Results: Cirrhosis and gastritis were present in 50 and 40 patients respectively, H. pylori serological assay and histological identification of the bacterium were positive in 35 (44%) and 19 (24%) patients respectively. Discrepancy between the 2 tests were observed more frequently in cirrhotic patients. A positive serology with a negative histologic examination for H. pylori was present for 18 cirrhotic and 4 noncirrhotic patients (p < 0.05). A gastritis without evidence of H. pylori was more frequent in cirrhotic than in noncirrhotic patients. H. pylori was histologically present in 11 of 29 cirrhotic patients and in 8 of the 11 noncirrhotic patients with a gastritis (p < 0.05).
Conclusions: Discrepancies between histological examination and H. pylori serology in patients with cirrhosis might be due to the inhospitable environment for H. pylori in case of portal hypertension; the positive serology could be in relation with a past infection.

This study identifies independent predictive indicators to distinguish autoimmune gastritis from ()-induced atrophic gastritis and validates their diagnostic performance to compare laboratory indicators of autoimmune gastritis and -induced atrophic gastritis. A retrospective comparison of laboratory examination indicators was conducted for chronic atrophic gastritis patients with involvement of the gastric fundus and corpus, who were followed up at the Department of Gastroenterology, Xijing Hospital, from January 2014 to September 2024. Receiver operating characteristic (ROC) curves were utilized to determine the optimal cutoff points and corresponding diagnostic thresholds.

Background: Hookworm infection remains of considerable importance to public health. However, because critical cases caused by hookworm infection are rarely observed in China, accurate and prompt diagnoses are difficult to achieve in clinical practice. In this study, we describe how we combined morphological and molecular approaches to achieve the clinical diagnosis of hookworm infection.

Epidermolysis bullosa (EB) is a group of rare genetic skin disorders that are hereditary and heterogeneous, characterized by skin and mucosal fragility and blister formation, often induced by minimal trauma. Esophageal complications represent a significant extracutaneous manifestation of EB. The lack of standardized diagnostic and therapeutic guidelines of EB with esophageal complications contributes to inconsistent management and a higher susceptibility to recurrence.
