Helicobacter pylori-mediated gastritis induces local downregulation of secretory leukocyte protease inhibitor in the antrum

Infect Immun. 2004 Apr;72(4):2383-5. doi: 10.1128/IAI.72.4.2383-2385.2004.

Abstract

Helicobacter pylori-infected subjects exhibited a strong decline in antral secretory leukocyte protease inhibitor (SLPI) levels compared to H. pylori-negative subjects and subjects from whom H. pylori had been eradicated (P = 0.002). This reduction was specific for the antrum, whereas SLPI expression in corpus and duodenum was not affected. Antral SLPI levels were inversely correlated with inflammatory scores of antrum-predominant gastritis.
