Patients with chronic hepatitis C achieving a sustained virological response to peginterferon and ribavirin therapy recover from impaired hepcidin secretion.

Background/aims: The aim of this study is to determine the clinical relevance of hepatic producing iron regulatory hormone-hepcidin, on iron overload in patients with chronic hepatitis C (CHC).

Methods: Serum hepcidin was measured in 73 CHC patients by surface-enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS), and compared to those of healthy controls and anemia of inflammation patients, and analyzed their relationship to hepatic hepcidin mRNA expression levels and clinical, hematological, and histological findings. The sequential changes of hepcidin were investigated in 27 CHC patients treated with a 48 week-course of pegylated-interferon (PEG-IFN) plus ribavirin therapy.

Copper- and iron-rich matrices in hepatocellular lipofuscin particles of a young male patient: diagnostic ultrastructures for Wilson disease.

A 17-year-old male patient appeared with the biochemical liver damage associated with hypoceruloplasminemia and mild iron overload. Genetic analysis identified a compound heterozygosity of ATP7B responsible for the primary copper toxicosis of Wilson disease without mutations in HFE. A liver specimen consisted of cirrhotic nodules of large-sized hepatocytes with fatty change and those of fat-free small-sized hepatocytes.

Genetic background of primary iron overload syndromes in Japan.

The different prevalences of iron overload syndromes between Caucasians and Asians may be accounted for by the differences in genetic background. The major mutation of hemochromatosis in Celtic ancestry, C282Y of HFE, was reported in a Japanese patient. Five patients of 3 families with the hepatic transferrin receptor gene (TFR2)-linked hemochromatosis were found in different areas of Japan, suggesting that TFR2 is a major gene in Japanese people.
