Serum Concentration of Inflammatory Cytokines in Dogs with Suspected Acute Pancreatitis

초록

Acute pancreatitis is an acute inflammatory process in the pancreas that is common in dogs. This study was designed to compare cytokines between healthy dogs and dogs with suspected acute pancreatitis. For the canine cytokine antibody array, three healthy dogs and three dogs with suspected acute pancreatitis were included. Interleukin (IL)-2, IL-6, IL-10, GM-CSF, and TNF-alpha were not detected in either group based on the results. Conversely, IL-8 (p = 0.035), Monocyte Chemoattractant Protein-1 (MCP)-1 (p = 0.0138), Receptor for Advanced Glycation Endproducts (RAGE) (p = 0.0079), and stem cell factor (SCF) (p = 0.034) were significantly increased in dogs with suspected acute pancreatitis. However, vascular endothelial growth factor (VEGF) (p = 0.6971) did not differ significantly between groups. For the canine serum Enzyme-Linked Immunosorbent Assay (ELISA), eight healthy dogs and eight dogs with suspected acute pancreatitis were included. ELISA revealed that IL-8 (p < 0.0001), MCP-1 (p < 0.0001), RAGE (p = 0.006), and SCF (p = 0.0002) were all significantly upregulated in the experimental group. We confirmed multiple patterns of cytokines in suspected acute pancreatitis of dogs via canine cytokine antibody array using a small quantity of serum. After this procedure, we reevaluated the cytokines, which were significantly increased in dogs with suspected acute pancreatitis, by ELISA, with more samples. Through this study, we confirmed that MCP-1, RAGE, and SCF were newly suggested factors in dogs with suspected acute pancreatitis.
