Background: Prognostic indicators in patients with decompensated cirrhosis are vital for the estimation of death risk. The ratio of C-reactive protein to albumin (CAR) has been verified as a prognostic marker in patients with hepatocellular carcinoma and decompensated cirrhosis related to hepatitis B virus. Neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and gamma globulins have been separately studied in cirrhosis. We evaluated the predictive role of CAR and other inflammatory markers in decompensated patients.

Methods: We prospectively studied 159 patients with stable decompensated cirrhosis, calculating the following indexes: CAR, NLR, LMR, Child-Turcotte-Pugh (CTP), and model for end-stage liver disease (MELD).

Results: MELD (area under the curve [AUC] 0.814) and CTP score (AUC 0.752) were superior to the other markers above in predicting patients' mortality (P<0.05). Patients with CAR<2.17 (median value) presented better times of survival: 20 months (12-27) vs. 14 months (10-17) (log rank P=0.015). NLR and LMR barely discriminated patients' prognosis. In multivariate analysis, only MELD and CTP scores were significant risk factors, whether using the proposed cutoff of 1.3 (hazard ratio [HR] 1.17 [1.106-2.44], P<0.001) or the median 2.17 CAR categorical variable (HR 1.17 [1.104-1.243], P<0.001). When patients who underwent liver transplantation were excluded, apart from the MELD and CTP scores CAR 2.17 was the only significant factor associated with the outcome (HR 3.61 [0.96-13.6], P=0.05) and detected different survival times: 10 (1-48) vs. 11 (2-38) months, log rank P=0.003. Patients with LMR≥1.9 presented significantly better renal function, in terms of true glomerular filtration rate (80±34 vs. 64±33 mL/min, P=0.004) and creatinine levels: 0.84 (0.1-1.8) vs. 0.98 (0.59-3.3) mg/dL (P=0.001).

Conclusion: Our findings demonstrate the significance of CAR and LMR in the outcome and renal function of decompensated patients.

Progressive systemic inflammation precedes decompensation in compensated cirrhosis.

JHEP Rep

February 2025

Department of Gastroenterology and Hepatology, Hospital Universitario Ramón y Cajal, Instituto Ramon y Cajal de Investigación Sanitaria (IRYCIS), Universidad de Alcalá, Madrid, Spain.

Background & Aims: Systemic inflammation is a driver of decompensation in cirrhosis with unclear relevance in the compensated stage. We evaluated inflammation and bacterial translocation markers in compensated cirrhosis and their dynamics in relation to the first decompensation.

Methods: This study is nested within the PREDESCI trial, which investigated non-selective beta-blockers for preventing decompensation in compensated cirrhosis and clinically significant portal hypertension (CSPH: hepatic venous pressure gradient ≥10 mmHg).

Clinical consequence of hypophosphatemia during antiviral therapy for chronic hepatitis B.

Kidney Res Clin Pract

Division of Nephrology, Department of Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea.

Background: Antiviral therapy is an essential treatment for chronic hepatitis B (CHB) infection. Although hypophosphatemia is an important adverse effect of antiviral agents, its clinical significance remains unclear. We investigated the incidence and clinical consequences of hypophosphatemia in a large cohort of CHB patients.

Metabolic Dysfunction-Associated Steatotic Liver Disease and the Cardiovascular System.

Trends Cardiovasc Med

January 2025

Department of Cardiology, Euroclinic Hospital, Athens, Greece; First Department of Cardiology, Athens University School of Medicine, Athens, Greece. Electronic address:

Metabolic dysfunction-associated steatotic liver disease (MASLD), previously termed nonalcoholic fatty-liver disease, is an important and rising health issue with a link with atherosclerotic cardiovascular (CV) disease (CVD), affecting ∼25-30% of the adults in the general population; in patients with diabetes, its prevalence culminates to ∼70%; its evolutive form, nonalcoholic steatohepatitis, is estimated to be the main cause of liver transplantation in the future. MASLD is a multisystem disease that affects, besides the liver, extra-hepatic organs and regulatory pathways; it raises the risk of type 2 diabetes mellitus (T2D), CVD, and chronic kidney disease; the disease may also progress to hepatocellular carcinoma. Its diagnosis requires hepatic steatosis and at least one cardiometabolic risk factor and the exclusion of both significant alcohol consumption and other competing causes of chronic liver disease.

Background: Small Intestinal Bacterial Overgrowth (SIBO) has been implicated in the pathophysiology of chronic liver disease (CLD). We conducted a systematic review and meta-analysis to assess and compare the prevalence of SIBO among CLD patients (with and without with complications of end stage liver disease) and healthy controls.

Methods: Electronic databases were searched from inception up to July-2024 for case-control studies reporting SIBO in CLD.

Intra-Abdominal Hypertension and Its Prognostic Impact on Mortality in Cirrhotic Patients with Ascites: The Role of Paracentesis.

Turk J Gastroenterol

January 2025

Division of Gastroenterohepatology, Department of Internal Medicine, İstanbul Faculty of Medicine, İstanbul University, İstanbul, Türkiye.

Background/aims: Elevated intra-abdominal pressure (IAP) can lead to intra-abdominal hypertension (IAH) and, in severe cases, abdominal compartment syndrome (ACS) in patients with cirrhosis and ascites. Paracentesis reduces IAP and improves abdominal perfusion. Intra-abdominal hypertension can also trigger acute-on-chronic liver failure (ACLF) in decompensated cirrhosis.
