Efficacy of Ulinastatin Combined with Continuous Renal Replacement Therapy in the Treatment of Sepsis Acute Kidney Injury and Its Effects on Systemic Inflammation, Immune Function and miRAN Expression

Abstract

Objective: To research the effectiveness of ulinastatin in combination with continuous renal replacement therapy in treating sepsis acute kidney injury and its effect on systemic inflammation, immune function and miRAN expression. Methods: The 84 patients who were diagnosed with sepsis complicated by acute kidney injury in our hospital between May 2020 and June 2022 were chosen and randomly assigned to the study group (n = 42) and the control group (n = 42). Ulinastatin in combination with continuous renal replacement therapy was administered to the study group, whereas the control group was administered with continuous renal replacement therapy alone. Both groups’ clinical effects were observed. The levels of blood urea nitrogen (BUN), serum creatinine (SCr), tumor necrosis factor- α (TNF- α ), high sensitivity Creactive protein (hs-CRP), vascular cell adhesion molecule-1 (VCAM-1), IgG, IgA, IgM, expression levels of miR-233 and miR-10a were compared among both the groups, pre-, and post-treatment. Results: The study group’s overall effectiveness rate was higher that is 95.24%, in comparison to the control group’s 78.57%, and this difference was statistically significant ( P < 0.05). Following the treatment, serum levels of BUN, Scr, TNF- α , hs-CRP, VCAM-1, and miR-233 and miR-10a expression levels in both the study and control groups were decreased, however, the study group had reduced levels in comparison to the control group, with statistically significant differences ( P < 0.05). Upon treatment, the serum levels of IgG, IgA, and IgM in both the study and control group were elevated, and the levels in the study group were greater in comparison to the control group, with statistically significant differences ( P < 0.05). Conclusion: Ulinastatin in combination with continuous renal replacement therapy for treating sepsis acute kidney injury exhibits a positive effect and can significantly improve the systemic inflammation and immune function in patients.
