Abstract
AIM: To investigate Fas expression and apoptosis of lymphocytes in severe acute pancreatitis (SAP) patients with and without sepsis.
METHODS: Fas expression and apoptosis of lymphocytes were examined by flow cytometry. Serum soluble Fas (sFas) levels were measured by enzyme-linked immunosorbent assay (ELISA) in 18 SAP patients (10 cases with sepsis, 8 cases without sepsis), 20 patients with mild acute pancreatitis (MAP), and 20 healthy volunteers (control).
RESULTS: Compared to the MAP and control groups, Fas expression, apoptosis of lymphocytes, and serum sFas levels increased significantly in the SAP group (all P < 0.01), and these changes were more significant in SAP patients with sepsis than in those without sepsis (38.37% ± 4.33% vs 26.34% ± 2.65%, 13.45% ± 2.99% vs 6.33% ± 2.05%, 9.89 ng/mL ± 1.25 ng/mL vs 7.36 ng/mL ± 0.95 ng/mL, all P < 0.01). There was no significant difference in Fas expression, apoptosis of lymphocytes, and serum sFas levels between the normal control group and MAP group. A significant positive relationship was observed between Fas expression and apoptosis of lymphocytes in SAP patients with sepsis (r = 0.988, P < 0.01).
CONCLUSION: The Fas signaling pathway may be involved in apoptosis of lymphocytes and is closely related to the severity of pancreatitis. Excessive apoptosis of lymphocytes appears to be related to immunosuppression and thereby results in the occurrence and development of sepsis in SAP patients.
