Introduction: The purpose of this study was to evaluate the impact of continuous veno-venous hemodialysis (CVVHD) using high cutoff (HCO) hemofilters on the removal of procalcitonin (PCT), and other inflammatory markers in the treatment of patients during septic shock with acute kidney injury (AKI).
Materials and methods: Thirty-six patients with septic shock and AKI were included in the study. Before and after the 24-h HCO-CVVHD, PCT, native C-reactive protein (CRP) and cytokines (interleukin-1β, interleukin-6, interleukin-12, interleukin-17, tumor necrosis factor-α) in serum and effluent were assessed.
Results: After the HCO-CVVHD serum concentrations of PCT, CRP and selected cytokines were significantly lower. The decrease in PCT was bigger than in CRP (p = 0.007). The change in PCT concentration was significantly influenced by PCT and IL-17 clearances (R2 = 0.525; p < 0.001).
Conclusion: In contrast to the native CRP, monitoring of PCT during HCO-CVVHD is less useful because it reflects the clearance of this marker and anti-inflammatory effectiveness of the method.
