Chronic Inactive Gastritis
Chronic inflammation of the stomach lining can be histologically classified as either chronic active or chronic inactive gastritis. Chronic inactive gastritis is inflammation characterized by lymphoplasmocytic infiltrates in the lamina propria in the absence of neutrophils. Chronic active gastritis is the presence of neutrophils in a background of lymphoplasmocytic infiltrates. Chronic active gastritis is considered a marker of continuing acute inflammation; in H. pylori gastritis neutrophils are seen in the presence of H. pylori, then subsequently disappear after the organism has been eradicated.
