The Prognostic Value of Procalcitonin in Critically Ill Cases of Systematic Inflammatory Response Syndrome in Dogs

Using markers for early diagnosis can help to reduce mortality and morbidity in systemic inflammatory response syndrome (SIRS). This study investigates the role of procalcitonin (PCT) as a prognostic value in dogs with SIRS in the intensive care unit. Fifty-five dogs were selected and studied. Blood samples were collected and investigated for PCT, white and red blood cells, iron, creatinine, platelet, glucose, albumin, urea, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), bandcell, body temperature, and hospitalized days and costs. The animals were grouped into survivors and deceased groups, and their results were compared. The results showed negative significant relations between PCT with hematocrit (  = 0.294,  < 0.05) and the serum concentration of iron (  = 0.280,  < 0.05) and also positive relation with IL-6 (  = 0.456,  < 0.01) and TNF-α (  = 0.391,  < 0.01). Significant relations were not seen between PCT with other parameters ( > 0.05). The results also showed a significant relation between glucose and albumin with body temperature ( < 0.05). The results showed that the serum concentrations of PCT, IL-6, and TNF-α were significantly higher in deceased dogs compared with survivors, while white blood cells, glucose, albumin, urea, lymphocyte, neutrophil, and body temperature were higher in survivors compared with others. PCT can be utilized as a prognostic value and helps early diagnosis in dogs with SIRS.
