Plasma ghrelin concentration correlates with the levels of serum pepsinogen I and pepsinogen I/II ratio--a possible novel and non-invasive marker for gastric atrophy.

Abstract

The plasma levels of ghrelin, which correlated well with the serum levels of PGI as well as the PGI/II ratio, decreased with increasing extent of gastric mucosal atrophy, suggesting that it could be a potentially useful non-invasive marker for chronic atrophic gastritis.
