Abstract:
Objective:To investigate clinical outcome and the risk factors for death in acute pancreatitis (AP) patients complicated with acute kidney injury (AKI).Methods:The clinical data of 232 AP patients complicated with AKI admitted to the Center of Severe Pancreatitis of Jinling Hospital Affiliated to Nanjing University School of Medicine from January 2016 to December 2020 were retrospectively analyzed. Patients were divided into survival group ( n=162) and death group ( n=70) based on the survival status. The two groups' clinical characteristics, biochemical indexes, and renal function indexes were compared. Univariate analysis and multivariate logistic regression analysis were used to analyze the independent risk factors for death in AP patients complicated with AKI. Results:Sixteen patients(6.9%) among the 232 had AKI Ⅰ, 15(6.5%) had AKI Ⅱ, and 201(86.6%) had AKI Ⅲ. Forty-one patients (17.7%) became AKI with a disease course <7 days, 184 patients (79.3%) gradually progressed to acute kidney disease with a disease course of 7-90 days, and 7 patients (3.0%) eventually progressed to chronic kidney disease with a disease course >90 days. Renal replacement treatment (RRT) was administered in 179 patients (77.2%), lasting an average of 14 (7-25) days. 138 patients (59.5%) had their renal function recovered while they were hospitalized, including 9 patients (6.5%) who did so within 7 days, 69 patients (50.0%) within 30 days, and 127 patients (92.0%) within 90 days. The average recovery time was 16 (7-28) days. Seventy patients (30.2%) died during hospitalization, including 8(3.5%) within 7 days, 42(18.1%) within 30 days, and 68(29.3%) within 90 days. Univariate analysis revealed that the proportions of biliary etiology, neutrophil to lymphocyte ratio (NLR), serum cystatin C, sequential organ failure assessment(SOFA) score, AKI Ⅲ proportion, number of patients undergoing RRT, and duration of AKI were significantly higher in the death group compared to the survival group. The number of patients complicated by infected pancreatic necrosis (IPN) and having surgical intervention was also significantly greater than that in the survival group, while the proportion of patients whose renal function recovered was much lower than that in the survival group. The differences were all statistically significant (all P value <0.05). Multivariate logistic analysis showed that SOFA( OR=1.182, 95% CI 1.000-1.396, P=0.049), and IPN( OR=8.403, 95% CI 3.748-18.838, P<0.001) were independent risk factors for death. Conclusions:SOFA score and IPN at admission were independent risk factors for death in AP patients with AKI. Vigilance should be given as soon as possible to improve the outcome of patients through clinical intervention.
