The effects of pirfenidone on T helper cells in prevention of intraperitoneal adhesions.

Abdominal surgery is linked with peritoneal adhesions. We investigated that the anti-fibrotic agent pirfenidone (PFD) has immune modulating activities and evaluated its effects on the function of T helper type 1 (Th1), Th2 and T regulatory (Treg) cells, which may play important roles in peritoneal adhesions. Eighteen female Wistar rats underwent right-sided parietal peritoneal and right uterine horn adhesion model.

Effect of Pirfenidone on Vascular Proliferation, Inflammation and Fibrosis in an Abdominal Adhesion Rat Model.

Aim: To study the efficacy of pirfenidone for prevention of postoperative adhesion formation in an adhesion rat model.

Materials And Methods: Eighteen female Wistar rats were subjected to right-sided parietal peritoneum and right uterine horn adhesion model. Rats were randomized into three groups: group 1 (control) (closure of midline abdominal incision without any agent administration), group 2 (closure of incision after intraperitoneal administration of pirfenidone), and group 3 (closure of incision and only oral administration of pirfenidone for 14 days).
