Incomplete Intestinal Metaplasia Is Rare in Autoimmune Gastritis.

Background: Incomplete intestinal metaplasia (IM) is reportedly associated with higher gastric cancer (GC) risk than its complete variant. AGA Guidelines recommend including IM subtyping in routine pathology reports. This study assesses the prevalence of complete versus incomplete IM in gastric conditions with different GC risks.

The Occurrence of Gastritis in Microscopic Colitis and Inflammatory Bowel Disease.

Multiple studies have shown that Helicobacter pylori infection is associated with a lower prevalence of inflammatory bowel disease (IBD). Besides chronic active gastritis (CAG) resulting from gastric infection with H pylori, pathologists have noticed another form of CAG, which is unrelated to H pylori infection and seems to cluster in patients with IBD. The aim of the present study was to compare the prevalence of H pylori-negative and H pylori-positive CAG in patients with IBD, and microscopic colitis (MC).

Lymphocytic gastritis and its relationships with other gastrointestinal disorders.

Background: Lymphocytic gastritis (LyG) is a histopathologic finding of unknown clinical relevance.

Aims: To explore the clinical epidemiology of LyG and its associations with Helicobacter pylori (Hp) infection, coeliac disease (CD) and microscopic colitis (MC) METHODS: In a cross-sectional study, the demographic, clinical, and histopathologic data of patients with and without LyG were compared. Between 2008 and 2020, 1.

Prevalence and concordant occurrence of esophageal, gastric, duodenal, and colonic eosinophilia.

Eosinophilic esophagitis, gastritis, duodenitis, and colitis are rare diseases. Few studies have been able to accumulate sufficiently large number of patients to analyze their clinical epidemiology. The aim of the present epidemiologic study was to examine the prevalence and concordant occurrence of gastrointestinal (GI) eosinophilia.

Gastric foveolar metaplasia and gastric heterotopia in the duodenum: no evidence of an etiologic role for Helicobacter pylori.

Gastric-type epithelium and islands of oxyntic mucosa in duodenal biopsies are considered by some to be part of a spectrum of metaplastic change related to peptic disorders. This study was designed to assess prevalence and associations of metaplastic-heterotopic gastric mucosa in the duodenum. Demographic, clinical, and histopathologic data from patients who had duodenal biopsy specimens for a 12-month period were collected from a national database.

Helicobacter heilmannii gastritis: a case study with review of literature.

H. heilmannii belongs to the Helicobacter family and is found in a small number of gastric biopsies. This bacterium is generally found in primates, cats, pigs, and carnivorous mammals.

Cleavage of CD14 and LBP by a protease from Prevotella intermedia.

Periodontitis is an inflammatory disease caused by subgingival microorganisms and their components, such as lipopolysaccharide (LPS). Responses of the host to LPS are mediated by CD14 and LPS-binding protein (LBP). In this study, it was determined that proteases from a periodontal pathogen, Prevotella intermedia, cleave CD14 and LBP, and thereby modulate the virulence of LPS.
