    Insights

    Hepatic steatosis (HS) in chronic hepatitis C (CHC) patients predicts lower sustained viral response (SVR) to treatment. Very low HS (<5%) is a negative predictor, but noninvasive factors like age and BMI can predict SVR with similar accuracy.

    Area of Science:

    • Hepatology
    • Virology
    • Internal Medicine

    Background:

    • Hepatic steatosis (HS) affects nearly 70% of chronic hepatitis C (CHC) patients.
    • HS is a negative predictor of sustained viral response (SVR) to standard of care (SOC) treatments like PEG-IFN and Ribavirin.
    • Assessing HS often requires invasive methods.

    Purpose of the Study:

    • To evaluate the predictive value of hepatic steatosis (HS) for sustained viral response (SVR) in chronic hepatitis C (CHC) patients treated with PEG-IFN and Ribavirin.
    • To compare the accuracy of invasive (histological) versus noninvasive variables in predicting SVR.
    • To identify noninvasive predictors that can replace invasive assessments for SVR prediction.

    Main Methods:

    • Retrospective analysis of biochemical, virological, and histological data from 72 CHC patients without metabolic syndrome.
    • Statistical analysis using logistic regression to determine the predictive accuracy of HS and other variables for SVR.
    • Comparison of SVR prediction models using invasive (fibrosis, HS) versus noninvasive (viremia, BMI, gender, age) variables.

    Main Results:

    • Overall accuracy of HS in predicting SVR was AUC=0.71 (p=0.005).
    • A HS cutoff of 5% significantly differentiated responders from non-responders (p=0.002), with 48% sensitivity and 91% specificity.
    • Combining conventional predictors with HS (>5%) achieved 75.0% accuracy in SVR prediction.
    • Noninvasive variables (gender, age, viremia, BMI) achieved 74% accuracy in predicting SVR, comparable to models including invasive factors.

    Conclusions:

    • Very low hepatic steatosis (<5%) is a negative predictor of SVR in CHC patients.
    • Noninvasive variables (gender, age, viremia, BMI) can effectively predict SVR with accuracy comparable to invasive assessments.
    • These findings support the use of noninvasive markers to predict treatment outcomes in CHC, potentially avoiding invasive procedures.

    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.

    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...

    Inhibitors of Viral Protein Synthesis

    Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...

    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...
