    Insights

    Dopplerography effectively assesses liver and spleen blood flow changes in chronic viral hepatitis B and C. Key indicators detect early disease and correlate with liver damage severity, aiding diagnosis.

    Area of Science:

    • Hepatology
    • Vascular Medicine
    • Diagnostic Imaging

    Background:

    • Chronic viral hepatitis B (CHB) and C (CHC) cause significant liver damage.
    • Assessing vascular changes is crucial for disease staging and management.
    • Histological evaluation is standard but invasive.

    Purpose of the Study:

    • To compare dopplerography findings of hepatic and splenic blood flow in CHB and CHC patients.
    • To correlate dopplerographic parameters with histological findings and liver sclerosis.
    • To evaluate dopplerography's utility in assessing liver morphology indirectly.

    Main Methods:

    • Study included 79 patients: 45 with CHB and 34 with CHC.
    • Dopplerography was used to characterize hepatic and splenic blood flow.
    • Results were correlated with histological activity index and sclerosis index.

    Main Results:

    • Congestion index, liver vascular index, and hepatic hypertension index were sensitive indicators.
    • These indices changed significantly even at minimal hepatitis activity and worsened with cirrhosis.
    • Venous blood flow was more severely affected than arterial flow; hyperperfusion progressed faster in CHC than CHB.

    Conclusions:

    • Dopplerography can evaluate hepatic and splenic vasculature in chronic viral hepatitis.
    • Dopplerographic parameters correlate with histological activity and sclerosis.
    • This non-invasive method offers indirect assessment of liver morphological changes.

    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...

    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...

    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...
    Portal Hypertension01:22

    Portal Hypertension

    Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...

    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...

    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...
