Histologic characteristics of Campylobacter pylori (Helicobacter pylori) mediated gastritis.
One hundred-nineteen specimens were reviewed to determine whether or not there were histologic changes specific for Campylobacter pylori (CP), (Helicobacter pylori) mediated gastritis. Hematoxylin and eosin (H&E), Brown-Hopp, and Wright-Giemsa stained sections were examined independently by two pathologists for (a) the presence of acute cryptitis, (b) percent and degree of crypt involvement, and (c) spectrum of inflammatory cells within the lamina propriae. The amount of mucus was quantified on the Periodic Acid Schift (PAS)-Alcian Blue stain sections. Changes in the character of the mucus were noted by using both the PAS-Alcian Blue and the High Iron Diamine-Alcian Blue. A positive specimen for Campylobacter pylori (CP+), (Helicobacter pylori) was defined as one in which curved or spiral shaped microbes were identified on Wright-Giemsa and Brown-Hopp stain. Seventy-eight specimens were CP+ and 41 CP-. Statistically significant histologic findings included the extent and degree of superficial cryptitis and the preponderance of plasma cells in CP+ cases. These findings confirm aspects seen in an animal model and suggest that there is an histologic pattern consistent with C. pylori (Helicobacter pylori) mediated gastritis.
