Insights

Iron deposits in liver tissue correlate with HFE gene mutations in patients with chronic liver disease (CLD). This finding aids in diagnosing hereditary hemochromatosis (HH) by linking liver iron levels to specific genetic markers.

Area of Science:

  • Hepatology
  • Medical Genetics
  • Clinical Biochemistry

Background:

  • Hereditary hemochromatosis (HH) diagnosis relies on tissue iron and genetic testing.
  • Chronic liver diseases (CLD) can present with iron deposition.
  • The HFE gene is crucial in HH pathogenesis.

Purpose of the Study:

  • To investigate the correlation between hepatic iron deposits and HFE gene mutations in CLD patients.
  • To assess the diagnostic utility of liver iron assessment in relation to HFE genotypes.

Main Methods:

  • Screening of HFE gene mutations (C282Y, H63D, S65C) using PCR-RFLP in 182 CLD patients.
  • Assessment of liver function, viral hepatitis serology, iron, ferritin, and semiquantitative liver iron.
  • Division of patients into groups based on the presence (Group B) or absence (Group A) of liver iron deposits.

Main Results:

  • Group B (with iron deposits) showed significantly higher biochemical markers of iron storage and ALT activity.
  • HFE gene mutations, including C282Y homozygotes and C282Y/H63D heterozygotes, were more frequent in Group B.
  • Chronic hepatitis C was the most common cause of CLD in the study population.

Conclusions:

  • Liver iron deposits identified in routine liver specimens correlate with the presence of various HFE gene mutations.
  • This correlation can enhance the diagnostic approach to hereditary hemochromatosis in patients with chronic liver disease.

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...
Hepatitis01:25

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...

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...

The Early Endosome: Endocytosis of Transferrin

Essential proteins such as insulin or low-density lipoprotein (LDL) and micronutrients such as iron enter a eukaryotic cell through receptor-mediated endocytosis. Subsequently, the early endosomes fuse with the vesicles containing such receptor-ligand complexes and play a vital role in sorting the incoming ligands and receptors. While the ligands are either degraded inside the vesicle or released into the cytosol, their receptors are returned to the plasma membrane for further rounds of...
