Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

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...

Summary

Transient elastography (TE) accurately assesses liver fibrosis. However, diagnostic performance and cutoff values differ between Asian patients with chronic hepatitis B and European patients with chronic hepatitis C due to various factors.

Area of Science:

  • Hepatology
  • Medical Imaging
  • Diagnostic Tools

Background:

  • Transient elastography (TE) is a non-invasive method to measure liver stiffness, correlating with fibrosis.
  • TE demonstrates good accuracy in predicting significant fibrosis and cirrhosis in chronic liver disease.
  • Most existing data on TE's clinical utility comes from European patients with chronic hepatitis C (CHC).

Purpose of the Study:

  • To compare the diagnostic performance of TE in Asian patients with chronic hepatitis B (CHB) against European patients with CHC.
  • To identify potential differences in TE's accuracy and optimal cutoff values between these distinct populations.
  • To inform the appropriate application of TE in diverse patient groups with chronic liver disease.

Main Methods:

  • Comparative analysis of transient elastography data.
  • Evaluation of diagnostic performance metrics (e.g., accuracy, cutoff values).
  • Consideration of confounding factors specific to Asian and European populations.

Main Results:

  • Diagnostic performance and cutoff values for TE varied between Asian CHB patients and European CHC patients.
  • Differences may be attributed to variations in disease etiology, histology, ALT levels, BMI, and metabolic syndrome prevalence.
  • TE shows acceptable accuracy for diagnosing fibrosis and cirrhosis in CHB patients.

Conclusions:

  • Transient elastography's effectiveness varies across different populations and liver disease etiologies.
  • Further research is needed to establish population-specific guidelines for TE use in Asian patients with CHB.
  • Tailored studies are crucial before widespread adoption of TE in Asian CHB cohorts.
