| Associated Dx | intestinal metaplasia of the stomach - esp. in chronic gastritis |
| Clinical history | dyspepsia |
| Symptoms | upper abdominal pain |

Gastritis refers to an inflammatory process that affects the stomach.
There are several types of gastritis:
- Chronic gastritis.
- Helicobacter pylori gastritis.
- Acute gastritis.
- "Chemical gastritis" - not really a gastritis; the preferred term is reactive gastropathy.
- Autoimmune gastritis.
- Lymphocytic gastritis.
- Collagenous gastritis.
This article gives an overview of causes of gastritis. It also deals with acute gastritis and the usual chronic gastritis without an apparent histologic cause.
Other forms of gastritis are dealt with in their own articles.
General
- Very common.
- A specific cause is uncommonly identified histologically.
Clinical:
- Dyspepsia - esp. upper abdominal pain.
Etiology
Gastritis causes:[1]
- Infectious:
- H. pylori infection.
- Tuberculosis.
- Salmonellosis.
- CMV.
- EBV.
- Syphilis.
- Endocrine-related:
- Pernicious anemia.
- Diabetes mellitus - gastric atony.
- Trauma, e.g. NG tube.
- Vascular, ischemia.
- Autoimmune:
- Toxins:
- Radiation.
Endoscopic appearance
- Erythematous.
Microscopic
- Inflammatory cells - see below.
Acute gastritis
- AKA active gastritis.
Features:
- Neutrophils - especially when intraepithelial.
Focal active gastritis
DDx:
Chronic gastritis
Features:
- Plasma cells (in lamina propria).
- Various criteria:
- Two plasma cells kissing, i.e. two plasma cells touching/overlapping.
- Three is a crowd, i.e. three plasma cells in close proximity.
- Various criteria:
Note:
- Approximately 20% of cases with an inflamed cardia will have intestinal metaplasia.[3]

Sydney criteria for gastritis
A bunch of pathologists in Sydney came-up with criteria... and these were revised in Houston.[4]
Classification
Updated Sydney classification:[4]
| Feature | Non-atrophic Helicobacter | Atrophic Helicobacter | Autoimmune |
| Inflammation pattern | antral or diffuse | antrum & corpus, mild inflammation | corpus only |
| Atrophy & metaplasia | nil | atrophy present, metaplasia at incisura | corpus only |
Notes:
- Corpus = gastric body.
- Incisura = angular incisure, incisura angularis (Latin) - notched transition point on lesser curvature of the stomach between pylorus and body.[5]
Severity
The Sydney group suggests grading severity with the following language:[4]
- Mild.
- Moderate.
- Marked.
These terms are applied to the parameters described in a biopsy. The Sydney criteria lists H. pylori, neutrophils, mononuclear cells, antrum (atrophy), corpus (atrophy) and intestinal metaplasia. The paper that discusses this also give a visual analogue scale.
Parameters & Severity (adapted from Dixon et al.[4]):
| Feature | Mild | Moderate | Marked |
|---|---|---|---|
| H. pylori | few touching | many touching | piles |
| Neutrophils | few | bunches | crowded |
| Mononuclear cells | not touching | kissing | partying |

Micro - inactive
The sections show gastric body type mucosa with small clusters of plasma cells. There are no intraepithelial neutrophils. Goblet cells are not identified. The epithelium matures normally to the surface. No Helicobacter organisms are seen.
