Hepatitis C, iron status, and disease severity: Relationship with HFE mutations

Abstract

Background & aims Mild to moderate hepatic iron loading is common in patients with chronic hepatitis C. We sought to determine whether mutations in the hemochromatosis gene, HFE, are associated with iron overload and acceleration of disease progression in hepatitis C patients.Methods A total of 316 patients with chronic hepatitis C were studied: 198 consecutive patients undergoing liver biopsy for compensated liver disease and 118 who underwent liver transplantation for end-stage liver disease. Serum iron studies, quantitative hepatic iron concentration, histologic activity index, and HFE genotype were determined.Results Among patients with compensated liver disease, the presence of HFE mutations was independently associated with elevations in serum iron level, serum transferrin-iron saturation, serum ferritin level, and hepatic iron index (P < 0.05). After adjustment for duration of infection with hepatitis C virus, HFE mutations were also independently associated with the presence of bridging fibrosis or cirrhosis (odds ratio, 18; 95% confidence interval, 1.7-193). HFE mutations were not independently associated with iron loading in patients with end-stage liver disease. There was no significant difference in the prevalence of HFE mutations between patients with compensated and end-stage liver disease (42% vs. 33%, respectively; P = 0.67).Conclusions The presence of HFE mutations is independently associated with iron loading and advanced fibrosis in patients with compensated liver disease from chronic hepatitis C, especially after controlling for duration of disease. These results suggest that HFE mutations accelerate hepatic fibrosis in hepatitis C but may not be responsible for progression to end-stage liver disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
