Abstract:
Objective:To evaluate the predictive value of systemic immune inflammation index (SII) for short-term prognosis in patients with sepsis complicated with acute kidney injury who received continuous renal replacement therapy (CRRT) .Methods:From Feb. 2018 to Jan. 2022, 90 patients with sepsis complicated with acute kidney injury who received CRRT in Hangzhou Cancer Hospital were included as the research objects. According to the survival of patients within 90 days, they were grouped into a survival group of 60 cases and a death group of 30 cases. The clinical baseline data such as age, sequential organ failure assessment (SOFA) score, acute physiological function and chronic health status scoring system II (APACHE II), albumin (ALB) were recorded. Automatic blood cell analyzer was applied to detect lymphocyte count, platelet count and neutrophil count in peripheral venous blood of patients with sepsis complicated with acute kidney injury who received CRRT, and the SII was calculated; Pearson correlation analysis was performed to analyze the correlation between SII and clinical baseline data in dead patients with sepsis complicated with acute kidney injury receiving CRRT; ROC curve was drawn to analyze and compare the predictive value of SII, SOFA score and APACHEII for death in patients with sepsis complicated with acute kidney injury receiving CRRT; Kaplan-Meier curve was performed to describe the changes in patient survival; multivariate Cox regression analysis was performed to analyze the factors affecting 90-day death in patients with sepsis complicated with acute kidney injury receiving CRRT.Results:SII (2636.74), C-reactive protein (CRP) [ (92.45±29.74) mg/L], SOFA score (12.83±3.24) and APACHEII (28.30±7.51) in the death group were higher than those in the survival group [341.92, (50.24±16.13) mg/L, 10.00±3.12, 25.13±6.87], and ALB [ (2.50±0.53) g/dl] was lower than that in the survival group [ (2.79±0.61) g/dl] ( P<0.05). SII was significantly positively correlated with CRP, SOFA score and APACHEII, and significantly negatively correlated with ALB in patients with sepsis complicated with acute kidney injury who received CRRT ( P<0.05). The areas under the curve (AUC) of SII, SOFA score, and APACHEII for predicting death in patients with sepsis complicated with acute kidney injury who received CRRT were 0.936, 0.827, and 0.736, respectively, and AUC of SII prediction was greater than that of SOFA score and APACHEII ( P<0.05). The 90-day survival rate of patients with sepsis complicated with acute kidney injury who received CRRT in the high SII group (23/46, 50.00%) was lower than that in the low SII group (37/44, 84.09%) ( P<0.05). SII was an independent risk factor for death within 90 days in patients with sepsis complicated with acute kidney injury who received CRRT ( P<0.05) . Conclusion:SII can better predict the 90-day mortality risk of patients with sepsis complicated with acute kidney injury receiving CRRT, and assist clinical assessment of short-term prognosis.
