To evaluate the effects of certolizumab, a pegylated monoclonal antibody to tumor necrosis factor α (TNF-α), on experimentally induced acute pancreatitis.


Healthy Wistar Albino male rats (n = 36) were randomly divided into 4 groups (9 rats in each group): group 1, control group; group 2, certolizumab group; group 3, cerulein group; and group 4, cerulein + certolizumab group. Acute edematous pancreatitis was induced via intraperitoneal injection of 80-μg/kg cerulein (20 μg/kg, 4 times at 1-hour intervals) in groups 3 and 4. Certolizumab (10 μg) was intraperitoneally administered in groups 2 and 4. Serum levels of amylase, lipase, TNF-α, and lactate dehydrogenase were evaluated. Histopathology and immunohistochemistry of the pancreatic tissue for assessing the activities of malondialdehyde, myeloperoxidase, TNF-α, and caspase-3 were also performed after 72 hours.


Certolizumab treatment significantly decreased the serum levels of amylase, lipase, and lactate dehydrogenase. Histopathological edema, hemorrhage, parenchymal necrosis, and infiltration scores were also decreased, along with a decrease in malondialdehyde, myeloperoxidase, TNF-α, and caspase-3 activities.


This study suggests that certolizumab is a beneficial treatment mode for reducing the severity of acute pancreatitis.
