A further case of sporadic congenital sideroblastic anaemia is reported. Despite no contributing factors such as blood transfusion, oral ingestion of iron or alcoholic beverages, were present excessive iron stores occurred with consecutive tissue damage resulting in cirrhosis of the liver, portal hypertension and diabetes mellitus. HLA phenotype was A3 B7 as in primary hemochromatosis. Correction of anemia was obtained by vitamin B6 administration. Improvement of iron overload was achieved through the use of daily subcutaneous infusions of the iron chelating drug desferrioxamine with a portable infusion pump.

Hemojuvelin (Hjv) is a membrane protein that controls body iron metabolism by enhancing signaling to hepcidin. Hjv mutations cause juvenile hemochromatosis, a disease of systemic iron overload. Excessive iron accumulation in the liver progressively leads to inflammation and disease, such as fibrosis, cirrhosis, or hepatocellular cancer.

Hereditary hemochromatosis is commonly associated with liver fibrosis. Likewise, hepatic iron overload secondary to chronic liver diseases aggravates liver injury. To uncover underlying molecular mechanisms, hemochromatotic hemojuvelin knockout (Hjv-/-) mice and wild type (wt) controls were intoxicated with CCl(4).

Background & Aims: Iron may influence severity and progression of non-hemochromatotic liver diseases. Our aim was to assess the relationship of iron and HFE genetic variations to progression and outcomes in the HALT-C Trial and whether PegIFN therapy influenced iron variables.
Methods: Participants were randomized to receive long-term PegIFN [n = 400] or no therapy [n = 413] for 3.

Nonalcoholic steatohepatitis (NASH) was described by Ludwig mainly in obese, middle-aged women, often associated with diabetes mellitus and hyperlipidemia. In the recent years, NASH was found to be associated with male, nonobese, nondiabetic patients and with liver iron overload, which led to the hypothesis of iron playing a role in NASH pathogenesis. Increased ferritin with normal transferrin saturation is frequently found in fatty liver patients, but it reflects iron overload only in those patients in which it persists despite an appropriate diet.

Background/aims: Hepatic iron may act as an important co-morbid factor in non-hemochromatotic liver diseases, but whether it may favour fibrogenesis after liver transplantation is not known. To verify whether the hepatic iron concentration of the graft might play a role in the rapid fibrotic progression frequently observed after liver transplantation for chronic hepatitis C.
Methods: The hepatic iron concentration, measured at the time of the donor operation, was retrospectively related to the histological follow-up data of 68 recipients (49 males, 19 females), of whom 38 were hepatitis C virus positive.
