What Is “Antrum Mucosa Erythematous”?

Definition of antrum mucosa erythematous: redness of the lining of the distal region of the stomach. Antral mucosal erythema is typically observed in gastritis patients.

Helicobacter pylori is a common cause of antral erythema, which is typically detected with an endoscopic biopsy. A proton-pump inhibitor, such as omeprazole, lansoprazole, or pantoprazole, coupled with an antibiotic and bismuth preparation for 10 to 14 days is the standard treatment for H. pylori infection.

Overuse of NSAIDs, or nonsteroidal anti-inflammatory drugs, such as aspirin, ibuprofen, and naproxen, is an additional major cause of acute and chronic gastritis.

Gastritis, or inflammation of the lining of the stomach, may be erosive or non-erosive. It is also categorised according to the location of inflammation within the stomach. PMN, or polymorphonuclear, infiltration into the antrum or body of the stomach lining is diagnostic of acute gastritis. Diagnosis of chronic gastritis is based on the presence of atrophy, typically involving the antrum of the stomach.

Gastritis can develop either rapidly or gradually over time. If left untreated, gastritis can progress to ulcers, and in certain circumstances, stomach cancer. Generally speaking, gastritis is not a dangerous ailment, and the majority of patients respond well to medical therapy.
