ABSTRACT 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.
Participants were randomized to receive long-term PegIFN [n = 400] or no therapy [n = 413] for 3.5 y, with follow-up for up to 8.7 y [median 6.0 y]. Associations of patient characteristics with iron variables at baseline and over time were carried out using Kaplan-Meier analyses, Cox regression models, and repeated measures analysis of covariance.
Participants who developed clinical outcomes [CTP > 7, ascites, encephalopathy, variceal bleeding, SBP, HCC, death] had significantly higher baseline scores for stainable iron in hepatocytes and in portal tract cells than those without. There were significant direct correlations between stainable iron in portal triads and lobular and total Ishak inflammatory and fibrosis scores [P < 0.0001]. Iron in triads at baseline increased risk of outcomes (HR = 1.35, P = 0.02). Stainable iron in hepatocytes decreased, whereas that in portal stromal cells increased significantly [P < 0.0001] over time. Serum iron and TIBC fell significantly over time [P < 0.0001], as did serum ferritin [P = 0.0003]. Chronic PegIFN treatment did not affect stainable iron. HFE genetic variations did not correlate with outcomes, including development of hepatocellular carcinoma.
Stainable iron in hepatocytes and portal tract cells is a predictor of progression and clinical and histological outcomes in advanced chronic hepatitis C. Chronic low-dose PegIFN therapy did not improve outcomes, nor iron variables.

    • "The complexity of the interplay between iron and CHC is underscored by recent finding that mutations in HFE, particularly the common H63D variation, while being associated with higher hepatic and total body iron, is also related to a significantly higher likelihood of complete and sustained responses to antiviral therapy [78]. A recent study shows that stainable iron in hepatocytes and portal tract cells is a predictor of progression and clinical and histological outcomes in advanced chronic hepatitis C while chronic administration low-dose of peginterferon did not improve outcomes, nor iron variables [79].

    ABSTRACT: NATURAL HISTORY OF HCV RELATED CHRONIC HEPATITIS IS INFLUENCED AND MODIFIED BY MANY FACTORS: virus features, coinfections and host characteristics. In particular, a peculiar genetic background of the host by conditioning the occurrence of intracellular metabolic derangements (i.e., insulin resistance) might contribute to accelerate the rate of progression to cirrhosis and eventually the occurrence of hepatocellular carcinoma (HCC) and death. Likely, direct interplays between virus genotype and host genetic background might be hypothesized at this level. Morbidity and mortality in cirrhosis is primarily associated with complications of liver cirrhosis (ascites, hepatic encephalopathy, jaundice, and gastroesophageal bleeding) and HCC occurrence. Therefore the main goal of therapy is to clear viral infection and decrease liver necro-inflammation that directly relates to development of cirrhosis and HCC. Among patients treated with Interferon-based therapy, those with sustained viral response showed a significant reduction of progression to cirrhosis and development of HCC. However, a residual risk of hepatocellular carcinoma still remains indicating the need for careful follow-up using ultrasonography every six months in cirrhotic patients, even in those showing persistently normal ALT and undetectable HCV RNA levels after antiviral therapy.

    ABSTRACT: The liver is the major iron storage organ in the body, and therefore iron metabolic disorder is sometimes involved in chronic liver diseases. Chronic hepatitis C is one of the liver diseases that show hepatic iron accumulation. The present review highlights the current concept of hepatic iron overload status in chronic hepatitis C and discusses how iron metabolic disorder develops in this disease, and the impact of hepatic iron overload on disease progression and its relevance to hepatocarcinogenesis. The level of hepatic iron accumulation in chronic hepatitis C should be recognized to be basically mild to moderate and sometimes within the normal range. However, even mild to moderate iron overload in the liver contributes to disease progression and hepatocarcinogenesis in chronic hepatitis C, probably by reinforcing the oxidative stress induced by hepatitis C virus (HCV) protein. The mechanisms by which hepatic iron overload develops in chronic hepatitis C have not been fully elucidated. Reduction of the transcription activity of hepcidin by HCV-induced reactive oxygen species may in part account for it, but the regulation of hepcidin is very complex and may depend on many variables, including the particular stage of the systemic and/or hepatic inflammatory conditions and the circulating transferrin-bound iron and intracellular iron stores. This might explain the variations in hepatic iron concentrations reported among patients with HCV-related chronic liver disease.

    ABSTRACT: There is much controversy surrounding the natural history of hepatitis C virus (HCV) infection. The aim of this review was to review the natural history of HCV infection. Published English literature was searched via pubmed and then reviewed. Approximately, 75-85% of HCV-infected persons will progress to chronic HCV infection. The rate of chronic HCV infection is affected by a person's age, gender, race, and viral immune response. Once chronic HCV infection develops, there are external and host factors that can increase the risk of progression of liver disease. Progression of chronic HCV infection is not linear in time, probably because many cofactors change the rate of development of fibrosis, cirrhosis, and hepatocellular carcinoma. Factors linked with aggressive disease progression include age at infection, duration of infection, heavy alcohol use, co-infections with HIV or hepatitis B virus, male sex, steatosis, insulin resistance (and factors associated with the metabolic syndrome), and host genetics. However, the relative importance of many and varied factors remains uncertain, and further research efforts should be directed toward design of predictive models for effective risk stratification. Interferon-based therapy, particularly among those achieving a sustained virologic response (SVR), is associated with improved fibrosis and inflammation scores, reduced incidence of hepatocellular carcinoma, and prolonged life expectancy. Despite the progress in understanding the factors affecting the natural history of HCV infection, a great deal remains to be learnt.
