Expression of Proteinase-activated Receptor-2 in the Esophageal Mucosa of Gastroesophageal Reflux Disease Patients: A Histomorphologic and Immunohistochemical Study

Data are limited regarding the role of proteinase-activated receptor-2 (PAR-2) in the esophageal mucosa in gastroesophageal reflux disease (GERD) patients. Our aim was to study PAR-2 expression and its relationship with different GERD-related clinical and pathologic parameters. Histomorphologic alte...

Zusammenfassung:Data are limited regarding the role of proteinase-activated receptor-2 (PAR-2) in the esophageal mucosa in gastroesophageal reflux disease (GERD) patients. Our aim was to study PAR-2 expression and its relationship with different GERD-related clinical and pathologic parameters. Histomorphologic alterations in eosophageal mucosa in nonerosive reflux disease (NERD) and erosive reflux disease (ERD) were also, evaluated. Endoscopic biopsies of the esophageal mucosa were obtained from 94 GERD patients and 20 participants for histopathologic analysis and PAR-2 immunohistochemical staining. The present study demonstrated significantly higher PAR-2 expression in GERD patients compared with control, whereas no significant differences were seen between NERD and ERD groups. PAR-2 expression significantly correlated with histologic score (r=0.572, P
