What is Chronic Gastritis?

Chronic Gastritis
Antral mucosa. Normal (A): Normal number of antral G cells with typical “hallo” appearances occur in neck area of the pyloric glands (arrows). Non-atrophic chronic gastritis (B): Mononuclear inflammation occupies the whole mucosa giving an impression of gland loss (atrophy). Atrophic gastritis of mild to moderate degree in antrum (C): Inflammation is relative mild but there is a large area of pyloric glands lost and replaced with metaplastic glands (IM) as indicated with arrows. Severe atrophic gastritis in antrum (D): All pyloric glands are gone and the whole mucosa is “intestinalized”. Inflammation is mild, or moderate at most. Also the antral G cells are disappeared along with the loss of the normal pyloric glands. Therefore, the G-17 feedback response in physiological control of acid secretion is impaired.

Chronic gastritis is a long-term condition in which the mucus lined layer of the stomach, also known as the gastric mucosa, is inflamed or irritated over a longer period of time. Symptoms tend to appear slowly, over time.

What is the Pathology of Chronic Gastritis?

The pathology of chronic gastritis is:

-Etiology: The cause of chronic gastritis is: the presence of bacteria H. pylori, long-term use of certain medications aspirin and ibuprofen,excessive alcohol consumption, certain illnesses diabetes or kidney failure, a weakened immune system.

-Genes involved: c-Myc and p53.

-Pathogenesis: The sequence of events that lead to chronic gastritis are the continuous mucosal injury due to long-standing H. pylori infection, leads to atrophy of stomach. This continuous pathological process results in erosion or ulceration of the mucosa leading to the destruction of the glandular layer and followed by fibrous replacement.

-Histology: The histology associated with chronic gastritis shows inflammatory infiltrates of neutrophils localized on the foveolar layer stroma of gastric mucous membrane in the case of acute gastritis. Chronic gastritis is characterized by an infiltrate of lymphoid cells, plasmatic cells and acidophilic granulocytes.

How does Chronic Gastritis Present?
