Abstract:
Objective:To analyze the risk factors and clinical characteristics of liver injury in patients with sepsis and to provide a reference for early recognition, early diagnosis, early intervention, and improve the survival rate of patients.Methods:The clinical data of sepsis patients admitted to the department of general intensive care unit (ICU) of the Second Affiliated Hospital of Zhejiang University School of Medicine from July 2014 to October 2020 were retrospectively analyzed. According to the occurrence of acute liver injury, patients with sepsis were divided into the liver injury group and the non-liver injury group, and the differences of demographic data, history, history of primary diseases, laboratory indicators on the first time of admission, treatments, the severity of the disease and other indicators were compared and analyzed. Logistic regression was used to analyze the risk factors for sepsis-related liver injury.Results:A total of 527 patients with sepsis were enrolled, and 129 patients with acute liver injury, accounting for 24.48%. Compared with the non-liver injury group, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), sequential organ failure assessment (SOFA), pro-brain natriuretic peptide (pro-BNP), serum MB isoenzyme of creatine kinase (CK-MB), total bile acid (TBA), serum creatinine (SCr), blood urea nitrogen (BUN), lactic acid (Lac), lactate dehydrogenase (LDH), C-reactive protein (CRP), procalcitonin (PCT) in liver injury group were significantly increased [APACHEⅡ score: 23.00±10.40 vs. 16.10±8.10, SOFA score: 9.17±4.29 vs. 5.90±3.12, pro-BNP (ng/L): 5 500.0 (1 166.0, 16 865.0) vs. 1 377.2 (448.8, 6 136.5), CK-MB (U/L): 23.0 (13.0, 55.0) vs. 18.0 (13.0, 31.0), TBA (μmol/L): 5.0 (2.4, 12.9) vs. 2.6 (1.4, 4.9), SCr (μmol/L): 146.0 (75.0, 222.0) vs. 71.0 (52.0, 125.8), BUN (mmol/L): 13.4 (8.8, 20.2) vs. 7.9 (4.9, 11.6), Lac (mmol/L): 2.0 (1.4, 4.4) vs. 1.4 (1.0, 2.2), LDH (μmol·s -1·L -1): 6.43 (3.76, 11.99) vs. 4.55 (3.38, 6.63), CRP (mg/L): 113.0 (61.8, 201.0) vs. 95.0 (37.3, 170.1), PCT (μg/L): 3.8 (1.0, 23.3) vs. 0.8 (0.2, 6.4)], prothrombin time (PT), international standard ratio (INR) and activated partial thrombin time (APTT) were significantly longer [PT (s): 19.4±7.6 vs. 16.0±4.0, INR: 1.7±1.0 vs. 1.3±0.5, APTT (s): 54.0±25.8 vs. 44.1±15.1], plasma fibrinogen (FIB), platelet count (PLT), albumin (ALB), and cholesterol (CHOL) were decreased [FIB (g/L): 4.2±2.3 vs. 4.9±1.8, PLT (×10 9/L): 116.3±74.3 vs. 182.7±108.6, ALB (g/L): 25.4±5.5 vs. 27.6±5.5, CHOL (mmol/L): 2.5±1.2 vs. 3.2±1.3], the probability of shock was significantly increased (91.47% vs. 59.19%), and the duration of shock was prolonged [days: 5.0 (2.0, 9.0) vs. 1.0 (0.0, 3.0)], positive rate of microbial culture (81.40% vs. 71.11%), probability of occurrence of drug-resistant bacteria (67.44% vs. 47.99%) were significantly higher, mechanical ventilation time [days: 6.0 (2.0, 12.7) vs. 2.4 (0.0, 6.9)], continuous renal replacement therapy (CRRT) time [days: 1.2 (0.0, 5.0) vs. 0.0 (0.0, 0.0)], the length of intensive care unit (ICU) stay [days: 9.0 (5.0, 18.0) vs. 7.0 (3.0, 13.0)] were significantly longer, 28-day mortality was significantly higher (80.62% vs. 28.89%), and the differences were statistically significant (all P < 0.05). Further Logistic regression analysis showed that PLT decline, PT prolongation, CRRT duration, shock duration and 28-day mortality were correlated with sepsis-related liver injury [odds ratios ( OR) and 95% confidence interval (95% CI) were 0.992 (0.987-0.998), 3.103 (1.507-6.387), 1.198 (1.074-1.336), 1.196 (1.049-1.362), and 0.213 (0.072-0.633), respectively, all P < 0.05]. Conclusions:Prolonged PT and decreased PLT are independent risk factors for sepsis complicated with liver injury. The long duration of CRRT, long duration of shock, and high mortality are independent clinical characteristics of patients with sepsis-related liver injury.
