Clinical efficacy of oXiris-continuous hemofiltration adsorption in septic shock patients: A retrospective analysis

Objective: This study aimed to assess the clinical impact of oXiris-continuous hemofiltration adsorption on patients with septic shock and their prognosis. Design: A retrospective study. Participants: Septic shock patients. Interventions: The oXiris group underwent hemofiltration adsorption using oXiris hemofilters and septic shock standard treatment, while the control group received septic shock standard treatment. Main variables of interest: The changes in inflammatory indicators and short-term mortality rate were evaluated. Propensity score matching (PSM) was conducted based on the 1:2 ratio between the oXiris and control groups to account for any baseline data differences. Results: Results showed that after 24 h, 48 h, and 72 h of treatment, PCT, IL-6, and hs-CRP levels in the oXiris group were significantly lower than those in the control group (P < 0.05). However, there were no significant differences in norepinephrine equivalents and organ function status (APACHE II score, SOFA score, Lac) between the two groups at the same time points. The 72-h mortality rate (21.88% vs. 34.04%) and the 7-day mortality rate (28.12% vs. 44.68%) were lower in the oXiris group compared to the control group, but not statistically significant. The 28-day mortality rate did not show a significant difference between the two groups (53.19% vs. 56.25%). Conclusions: oXiris continuous hemofiltration adsorption technology may reduce the levels of inflammatory factors in patients with septic shock; however, it does not appear to enhance organ function or improve the 28-day mortality rate in these patients.
