The Clinical and Laboratory Efficacy of HA 330 Treatment Combined with Continuous Renal Replacement Therapy in Septic Shock Patients: A Case Series

Abstract

Introduction: Blood purification therapy is a method used to enable cytokine removal and to improve disturbed immune homeostasis in patients with sepsis or septic shock. This study aimed to evaluate the impact of HA 330 treatment on biochemical and hemodynamic parameters and cytokine levels in adult patients with septic shock. Methods: Critically ill patients with septic shock who received continuous veno-venous hemodiafiltration and HA 330 treatment were included in this prospective observational study. Biochemical and hemodynamic parameters were followed throughout HA 330 treatment. Serum interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor (TNF)-α, high-mobility group box1 (HMGB-1) protein, IL-10 levels were analyzed by ELISA method, before and after each HA 330 session. Results: A total of 18 critically ill patients were included in this study. The median APACHE 2 score was 22.2 ± 7.49 and median SOFA score 9.6 ± 5.44 on intensive care unit admission. SOFA scores were significantly decreased on the 3rd day of HA 330 treatment, compared to 2nd day scores (p = 0.017). Median leukocyte value was significantly decreased (p = 0.027 and p = 0.024), while hemodynamic parameters remained unchanged throughout the HA 330 treatment. Median CRP and procalcitonin levels were significantly reduced at day 3 of HA 330 treatment compared to the baseline (p = 0.015 and p = 0.033, respectively). Serum IL-1 β, IL-6, IL-8, TNF-a, HMGB-1, and IL-10 levels decreased insignificantly by 11.5%, 26.4%, 11.4%, 37.9%, 0.02%, and 35.5%, respectively, at the end of the hemoperfusion treatment compared to the pre-treatment. Conclusion: The administration of HA 330-based hemoperfusion in septic shock patients revealed improvements in SOFA scores, leukocyte count, and CRP and procalcitonin levels. However, there was no statistically significant change in concentrations of inflammatory cytokines and hemodynamic parameters during HA 330 treatment.
