Antrum mucosa erythematous defined means erythema, or redness, of the lining of the distal portion of the stomach. Antral mucosal erythema is commonly seen in patients with gastritis.
Helicobacter pylori is a common cause for antral erythema, usually diagnosed with a biopsy taken during an endoscopy. Common treatment for H. pylori infection involves a triple-therapy regimen of a proton-pump inhibitor, such as omeprazole, lansoprazole or pantoprazole along with an antibiotic and bismuth preparation for 10 days to two weeks.
Another common cause for acute and chronic gastritis is the overuse of NSAIDs, or nonsteroidal anti-inflammatory medications, such as aspirin, ibuprofen and naproxen.
Gastritis, or inflammation of the stomach lining, can be either erosive or nonerosive. It is also classified based on where the inflammation occurs within the stomach. Acute gastritis is diagnosed by the PMN, or polymorphonuclear, infiltration within the antrum or body of the stomach lining. Chronic gastritis is diagnosed when there is atrophy found, usually involving the antrum of the stomach.
Gastritis can occur overnight, or it can develop slowly over time. Gastritis can lead to ulcers if not treated, and in some cases, it can lead to stomach cancer. Usually gastritis is not a serious condition, and most people respond quickly to medical treatment.
