Article Abstract

Urinary kidney injury molecule-1 (KIM-1), neutrophil gelatinase-associated lipocalin (NGAL), and serum cystatin C (Cys C) are biomarkers of acute kidney injury (AKI). However, the efficacy of combining these indices to diagnose decompensated cirrhosis is unknown. This study involved 150 patients divided into AKI and non-AKI, and healthy individuals. Urinary KIM-1 and NGAL, serum Cys and creatine, and glomerular filtration rate (GFR) were compared based on Child-Pugh liver function class. Urinary KIM-1 and NGAL concentrations and serum Cys C levels were significantly higher in patients with AKI secondary to decompensated cirrhosis than in those with AKI not secondary to decompensated cirrhosis (p < 0.01). These were significantly associated with higher kidney injury index stages (p < 0.01) and negatively correlated with GFR in secondary AKI patients. Urinary KIM-1 and NGAL and serum Cys C increased significantly and GFR decreased as Child-Pugh class of decompensated cirrhosis significantly increased (p < 0.05). SCr levels were significantly increased in Child-Pugh class C patients (p < 0.05). Urinary KIM-1, urinary NGAL, serum Cys C, and the combined detection factor, as screening indices, could aid in the early diagnosis of AKI secondary to decompensated cirrhosis.

Supplementary Material for Projected Global Clinical, Humanistic, and Economic Impact of Metabolic Dysfunction-Associated Steatohepatitis (MASH): The Cost of Inaction Based on Data from Nine Countries.

The Global NASH/MASH Council, Washington, DC, United States; Gastroenterology Section, Department of Medicine, King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia; Liver, Digestive, and Lifestyle Health Research Section, and Organ Transplant Center of Excellence, King Faisal Sp

Background And Aim: Although the clinical burden of MASH is well known, its economic burden is less well described. We estimated MASH's economic burden in several regions of the world including the US, Germany, Spain, France, Italy, and United Kingdom (UK), Japan, Saudi Arabia, and Brazil over the next two decades.

Methods: A one-year cycle Markov model projected MASH progression from 2021 to 2040, incorporating 2020 prevalent cases and annual incident cases (2021-2040).

Real-world use of terlipressin in cirrhosis and acute kidney injury: frequent use beyond hepatorenal syndrome.

Unit of Internal Medicine and Hepatology, Department of Medicine, University and Hospital of Padova, Padova, Italy. Electronic address:

Background & Aims: Terlipressin is indicated to treat hepatorenal syndrome (HRS)-acute kidney injury (AKI), but is likely used outside this primary indication in clinical practice. We aimed to investigate real-world practice patterns on the use of terlipressin in AKI in cirrhosis.

Methods: International prospective study including patients hospitalized for decompensated cirrhosis.

Introduction: Osler-Weber-Rendu syndrome, or hereditary hemorrhagic telangiectasia (HHT), is a rare autosomal dominant genetic vascular disease characterized by arteriovenous malformations, vascular wall fragility, dilatation, and rupture of the vessels with hepatic symptoms. As HHT with hepatic symptoms is recognized as the primary etiology for liver transplantation, liver transplantation with liver grafts from donors affected by HHT is extremely rare. Herein, we report a successful liver transplantation in a patient with biliary atresia who received a whole-liver graft from a young brain-dead donor with HHT.

Introduction: Cirrhosis progresses from compensated to decompensated phases, often marked by portal hypertension and complications like ascites, variceal hemorrhage, and hepatic encephalopathy. The ammonia-to-urea (A-to-U) ratio, reflecting urea cycle efficiency, may offer superior diagnostic performance compared to plasma ammonia levels alone. This study compared the diagnostic accuracy of the A-to-U ratio and plasma ammonia levels for identifying portal hypertension.
