Background: The chemokine monocyte chemoattractant protein‐1 (MCP‐1) is a primary regulator of monocyte mobilization from bone marrow, and increased concentrations of MCP‐1 have been associated with sepsis and other inflammatory disorders in critically ill people. The relationship between MCP‐1 and disease in dogs has not been evaluated previously. Objective: The purpose of this study was to assess serum concentrations of MCP‐1 in healthy dogs, dogs in the postoperative period, and critically ill dogs. We hypothesized that MCP‐1 concentrations would be significantly increased in critically ill dogs compared with postoperative or healthy dogs. Methods: Serum concentrations of MCP‐1 were measured in 26 healthy control dogs, 35 postoperative dogs, and 26 critically ill dogs. Critically ill dogs were further subgrouped into dogs with sepsis, parvovirus gastroenteritis, immune‐mediated hemolytic anemia, and severe trauma ( n =26). MCP‐1 concentrations were determined using a commercial canine MCP‐1 ELISA. Associations between MCP‐1 concentrations and disease status were evaluated statistically. Results: MCP‐1 concentration was significantly higher in critically ill dogs (median 578 pg/mL, range 144.7–1723 pg/mL) compared with healthy dogs (median 144 pg/mL, range 4.2–266.8 pg/mL) and postoperative dogs (median 160 pg/mL, range 12.6–560.4 pg/mL) ( P <.001). All subgroups of critically ill dogs had increased MCP‐1 concentrations with the highest concentrations occurring in dogs with sepsis. However, differences among the 4 subgroups were not statistically significant. Conclusion: Critically ill dogs had markedly increased serum concentrations of MCP‐1 compared with postoperative and healthy dogs. These results indicate that surgery alone is not sufficient to increase MCP‐1 concentrations; thus, measurement of MCP‐1 may be useful in assessing disease severity in critically ill dogs.
