title: Apparent reversal of early gastric mucosal atrophy after triple therapy for Helicobacter pylori.
abstract: Helicobacter pylori may be difficult to detect in individuals with intestinal metaplasia or atrophic gastritis, even though bacteria may persist in the mucosa in low numbers, maintaining elevated serum H. pylori antibody levels. We report a patient with marked, endoscopically visible gastric mucosal changes and focal changes of histological atrophic gastritis, who was negative for H. pylori on urease test, culture, and histology, but had positive H. pylori serology. When treated with triple therapy and reassessed at 6 months, his H. pylori antibody titer fell to low/negative levels, abnormal mucosa was replaced by a velvety, normal lining, and the previous evidence of histological atrophic gastritis was no longer detectable.
