Soluble triggering receptor expressed on myeloid cells (sTREM-1): a new mediator involved in the pathogenesis of peptic ulcer disease.

Objectives: Triggering receptor expressed on myeloid cells (TREM-1) is a promoter of cytokine production triggered by microbial components. To investigate the significance of its soluble counterpart, sTREM-1, for the pathogenesis of peptic ulcer disease, sTREM-1 was compared with the proinflammatory mediators and the pathology score of gastritis.

Methods: Forty patients with dyspepsia were enrolled: 20 with peptic ulcer and 20 controls without any macroscopic abnormalities.
