CHILD-TURCOTTE-PUGH /ALBUMINURIA AS A PREDICTOR OF ACUTE KIDNEY INJURY AMONG HOSPITALIZED PATIENTS WITH LIVER CIRRHOSIS

Abstract

Background: The incidence of acute kidney injury (AKI) in cirrhotic patients about fifteen percent of hospitalized cirrhotic patient, Prediction of AKI indicated in all patients with liver cirrhosis. Albuminuria in cirrhotic patient can predict AKI. Objective: To assess the role of Child-Turcotte Pugh/Albuminuria (CTP-Alb), in prediction of AKI among hospitalized patients with liver cirrhosis. Patients and Methods: After departmental ethics committee approval and patient consents were obtained, 60 patients with liver cirrhosis screened for AKI during hospital admission at hepatogastroenterology unit, Department of Internal Medicine in Al-Hussein Hospital, Al-Azhar University, and The study was carried out during the period from September 2019 and September 2020, The diagnosis of liver cirrhosis based on clinical, biochemical and ultrasonography findings. Patients with Fib-4 ≥ 3.5 in the absence of liver decomposition were categorized as compensated liver cirrhosis. Severity of liver disease was assessed using the CTP score, model for end stage liver disease (MELD) score and CTP-Alb score. Diagnosis of acute kidney injury was based on the changes in serum creatinine. The baseline renal assessment at first day of hospital admission was included serum creatinine, estimated glomerular filtration rate (eGFR), albumin/creatinine ratio, and abdominal ultrasonography. AKI was categorized as hepatorenal syndrome (HRS), pre-renal azotemia, post-renal azotemia or intrinsic acute kidney injury. Results: A total of 60 patients included. They were 40 (66.66%) males and 20 (33.34%) females. Their mean age was 50 ± 33 years, of them 8 (13.33%) patients developed AKI during hospital admission with their mean age was 60.6 ± 10.9 years. They were 5 (62.5%) males and 3 (37.5%) females, Hypoalbuminemia, Child score at admission and Child-albuminuria score at admission were identified as independent risk factors for AKI by multivariate analysis (p < 0.05). Conclusion: Thirteen percent of cirrhotic patients developed AKI during hospital admission according to our results. The majority of patients were child C in our series; CTP/Albuminuria score, Hypoalbuminemia and ACLF has promising sensitivity, specificity and accuracy in prediction of AKI in hospitalized cirrhotic patient.
