Evaluating Novel Scoring Systems to Predict Outcomes in Acute-on-Chronic Liver Failure

25. července 2026 aktualizováno: Rehab Hassan Abdel-hafiz Hassan, Assiut University

Evaluation of Novel Scores for Prediction of Outcomes in Patients With Acute-on-Chronic Liver Failure

Acute-on-chronic liver failure (ACLF) is a serious condition where a patient with long-term liver disease suddenly experiences severe liver worsening and failure of other organ systems, such as the kidneys or lungs. ACLF is associated with a high risk of short-term death, making early and accurate prediction of patient outcomes essential for guiding medical decisions.

Conventional scoring systems, such as the Child-Pugh and Model for End-Stage Liver Disease Sodium (MELD-Na) scores, are widely used to assess liver disease severity. However, these traditional models may not fully capture the intense systemic inflammation and multiorgan failure characteristic of ACLF. Recently, novel prognostic scoring models, specifically the CLIF-C ACLF-D score and the MELD-complication score, have been developed to better predict patient outcomes by integrating markers of inflammation, organ dysfunction, and clinical complications.

This study aims to evaluate and validate the clinical usefulness of these novel scoring models compared to conventional scores in predicting in-hospital and 28-day mortality among patients admitted with ACLF.

Participants enrolled in this prospective observational study will be recruited from the Intensive Care Unit (ICU) of the Tropical Medicine and Gastroenterology Department at Al-Rajhi University Hospital. Upon admission, participants will undergo routine clinical examinations, laboratory testing, and imaging. The various risk scores will be calculated at baseline. Participants will be monitored throughout their hospital stay, and their survival status will be followed for 28 days after admission to compare the accuracy of each scoring system.

Detailní popis

Acute decompensation in liver cirrhosis is the primary cause of hospitalization among cirrhotic patients. Acute-on-chronic liver failure (ACLF) represents a distinct, severe clinical entity characterized by systemic inflammation, single- or multiple-organ failures, and high short-term mortality. While traditional scoring systems like the Child-Pugh and Model for End-Stage Liver Disease Sodium (MELD-Na) scores are routinely utilized, they may fail to capture the complex inflammatory response and multiorgan involvement inherent to ACLF.

To improve prognostic estimation, novel predictive tools, including the CLIF-C ACLF-D score and the MELD-complication score, have been introduced, incorporating inflammatory parameters and complication markers. Validation of these prognostic models across distinct patient populations is necessary prior to broad implementation. This study evaluates the prognostic performance of these novel models in patients with ACLF admitted to the Intensive Care Unit (ICU).

All enrolled participants will undergo systematic evaluation upon admission:

  1. Clinical and Demographic Assessment: Full patient history (demographics, etiology of underlying chronic liver disease, previous episodes of decompensation, drug history) and comprehensive physical examination (vital signs, grade of hepatic encephalopathy, jaundice, asterixis, edema, and clinical signs of infection or ascites/pleural effusion).
  2. Laboratory Diagnostics: Complete blood count with differential, liver function tests (total and direct bilirubin, serum albumin), renal function parameters (serum creatinine, blood urea nitrogen), coagulation profile (prothrombin time, INR), serum electrolytes (sodium, potassium), C-reactive protein (CRP), arterial blood gas analysis, viral hepatitis markers (HBsAg, anti-HCV), ascitic fluid analysis (if applicable), and biological cultures from suspected infectious foci.
  3. Imaging: Abdominal ultrasonography (evaluating hepatic architecture, portal vein parameters, splenic dimensions, collateral circulation, biliary structure, renal status, ascites) and chest radiography.
  4. Scoring Calculation: Baseline risk scores-including Child-Pugh, MELD-Na, CLIF-C OF, CLIF-C ACLF, CLIF-C ACLF-D, and MELD-complication scores-will be calculated at admission using standard mathematical formulas and validated online platforms.

Participants will be followed throughout their hospital stay and up to 28 days following admission. Survival outcomes will be confirmed in-hospital or post-discharge via telephone follow-up or clinical visits.
