Insights

Mast cells are more numerous in children with chronic gastritis, especially those infected with Helicobacter pylori. These cells may significantly contribute to gastritis pathogenesis.

Area of Science:

  • Pediatric Gastroenterology
  • Immunology
  • Pathology

Background:

  • Chronic gastritis is a common condition in children.
  • Mast cells are immune cells implicated in inflammatory processes.
  • Helicobacter pylori infection is a major cause of pediatric gastritis.

Purpose of the Study:

  • To investigate the role of mast cells in pediatric chronic gastritis.
  • To compare mast cell density in children with and without H. pylori infection.
  • To assess mast cell degranulation in relation to H. pylori status.

Main Methods:

  • Histological analysis of gastric biopsies using toluidine blue and anti-human mast cell tryptase.
  • Evaluation of mast cell density in antrum and corpus.
  • Electron microscopy to assess mast cell degranulation.
  • Comparison of mast cell counts before and after H. pylori eradication.

Main Results:

  • Significantly increased mast cell density was observed in children with chronic gastritis, irrespective of H. pylori infection, compared to controls.
  • Mast cell degranulation was evident in children with H. pylori-positive chronic gastritis.
  • Mast cell density decreased after successful H. pylori eradication.

Conclusions:

  • Mast cells are significantly implicated in the pathogenesis of chronic gastritis in children.
  • Helicobacter pylori infection exacerbates mast cell involvement in pediatric gastritis.
  • Targeting mast cell mediators could be a therapeutic strategy for childhood chronic gastritis.

Pathophysiology of Peptic Ulcer Disease: Injurious Factors

Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...
Intestinal Phase of Digestion01:29

Intestinal Phase of Digestion

The intestinal phase of digestion is the third and final stage of the digestive process, occurring after the cephalic and gastric phases. It begins when chyme, a partially digested mixture of food and digestive enzymes, enters the small intestine from the stomach. This phase is crucial for nutrient absorption and involves complex hormonal and enzymatic interactions.
The arrival of the chyme in the small intestine distends the duodenum, which triggers the enterogastric reflex. This distension...
Mucosal Barrier of the Stomach01:25

Mucosal Barrier of the Stomach

The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Peptic Ulcer01:27

Peptic Ulcer

Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
Gastritis II: Pathophysiology01:26

Gastritis II: Pathophysiology

The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
