Insights

Hepatosteatosis (fatty liver) does not significantly impact liver stiffness measurements in most fibrosis stages of chronic hepatitis. Shear-wave elastography remains reliable for monitoring patients with fatty liver disease.

Area of Science:

  • Hepatology
  • Medical Imaging
  • Gastroenterology

Background:

  • Percutaneous liver biopsy (PLB) traditionally assesses fibrosis in chronic hepatitis (CH) using Ishak and Knodell classifications.
  • Hepatosteatosis (HS) is frequently observed in PLBs and may influence fibrosis evaluation.
  • Shear-wave elastography (SWE) is an emerging non-invasive technique for assessing liver fibrosis.

Purpose of the Study:

  • To evaluate the impact of hepatosteatosis on liver fibrosis assessment in chronic hepatitis.
  • To compare shear-wave elastography (SWE) measurements with Ishak-Knodell fibrosis grades in the presence of varying degrees of steatosis.
  • To determine if steatosis affects SWE (kPa) results within specific fibrosis grades.

Main Methods:

  • Chronic hepatitis cases were stratified into three groups based on the presence and percentage of hepatosteatosis (<10% or ≥10%).
  • Ishak-Knodell fibrosis grades and SWE values (kPa) were analyzed for all patients.
  • Statistical comparisons were performed to assess the relationship between steatosis, fibrosis grades, and SWE values.

Main Results:

  • Of 236 CH patients, 109 (46.2%) had HS, with 78 (71.5%) showing ≥10% steatosis.
  • No significant difference in liver stiffness (kPa) was found between HS groups for Ishak-Knodell grades except F3 (p > 0.05).
  • A significant difference in kPa values was observed for the F3 fibrosis grade (p < 0.05).

Conclusions:

  • Liver stiffness (kPa) measurements by SWE correlate well with fibrosis grades in chronic hepatitis.
  • SWE is a viable tool for monitoring CH patients with hepatosteatosis, potentially reducing the need for invasive procedures.
  • Non-invasive SWE assessment enhances patient comfort and avoids unnecessary liver biopsies.

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug binding...

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
