AI Article Synopsis
- Noninvasive techniques like vibration-controlled transient elastography and magnetic resonance elastography are effective for assessing liver fibrosis severity in chronic hepatitis C.
- Recent research highlights the correlation between liver stiffness measurements and liver fibrosis severity, indicating that higher stiffness values predict worse liver-related outcomes.
- A decrease in liver stiffness over time suggests successful treatment, while a lack of decrease can indicate treatment failure or relapse.*
Article Abstract
Introduction: The severity of liver fibrosis can be assessed noninvasively today by liver stiffness measurements. Vibration-controlled transient elastography, shear wave elastography or magnetic resonance elastography are techniques increasingly used for this purpose.
Methods: This article presents the recent advances in the use of new techniques for liver fibrosis assessment in chronic hepatitis C: the correlation between liver stiffness values and liver fibrosis estimated by liver biopsies, the prognosis role of liver stiffness values, their usefulness in monitoring the treatment response, in assessing the severity of portal hypertension and in estimating the presence of esophageal varices. Scientific articles from January 2017 to January 2018 were searched in PubMed and PubMed Central databases, using the terms "liver stiffness" and "hepatitis C".
Results: The median liver stiffness values measured with different techniques are not identical, so that FibroScan thresholds cannot be used on any other elastographic machine. The higher the liver's stiffness measurement, the higher the liver-related events in patients with chronic hepatitis C. A liver stiffness measurement over 17 kPa could be an independent predictor for the presence of esophageal varices as well as a spleen with a longitudinal span ≥ 15 cm for patients with a value of liver stiffness < 17 kPa. A progressive and persistent decrease in liver stiffness is dependent on sustained virological response achievement. The lack of liver stiffness decrease has been associated with relapsers and a low value of liver stiffness at baseline.
Conclusion: Liver stiffness provides clues about the severity and evolution of liver disease.

Background: The relationship between plasmatic fatty acid (FA) composition and liver fibrosis remains scarce in people living with HIV/AIDS (PLWHA). We aimed to evaluate the association of plasmatic FAs and liver fibrosis in HIV mono-infected individuals.
Methods: This case-control study included PLWHA with liver fibrosis (cases) and randomly selected subjects without fibrosis (controls) from the PROSPEC-HIV study (NCT02542020).

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a liver disease that is strongly associated with chronic low-grade inflammation. Stage 3 of MASLD is characterized by excessive formation of connective tissues, commonly referred to as liver fibrosis. Although numerous inflammatory markers have been identified and extensively studied, including the tumor necrosis factor-α and interleukin-6 have been studied [Byrne CD, Targher G.

Background And Aim: Identifying the factors contributing to the progression of metabolic dysfunction-associated steatotic liver disease (MASLD), a lifestyle-related disease, is crucial for preventing future liver-related deaths. This study aimed to epidemiologically investigate factors, including single-nucleotide polymorphisms (SNPs) associated with alanine aminotransferase (ALT) levels >30 U/L and potential risk factors for liver fibrosis, in a general population cohort of patients with MASLD.
Methods: Among 1059 participants in the health checkup project, 228 who were diagnosed with MASLD were analyzed.

Purpose: To evaluate the consistency and agreement between portal venous pressure measured by fine-needle (F), portal vein catheterization (D), and hepatic vein balloon-occlusion (W) in decompensated cirrhotic patients with intrahepatic venovenous shunts (IHVS).
Materials And Methods: 156 consecutive patients planning to receive transjugular intrahepatic portosystemic shunt in our center were screened for study participation. The F/D/W were assessed for consistency by Pearson coefficient (r), linear regression coefficient (R), and intraclass correlation coefficient (ICC), and for disagreement (error exceeding 20% of D) by Bland-Altman method.

Background: Portal hypertension (PH) resulting from static and dynamic intrahepatic changes drives liver-related complications even after removing the underlying aetiological factor.
Objective: We investigated the impact of inflammation on the dynamic component of PH during disease regression in animal models of toxin-induced cirrhosis and patients with alcohol-related cirrhosis.
Methods: In mice, cirrhosis was induced via toxin application for 12 weeks followed by toxin-withdrawal allowing for one or 2 weeks of regression.
