title: Body iron stores and iron restoration rate in Japanese patients with chronic hepatitis C as measured during therapeutic iron removal revealed neither increased body iron stores nor effects of C282Y and H63D mutations on iron indices.
abstract: Information on the level of iron stores in chronic hepatitis C is clinically important because its reduction is technically simple and therapeutically effective. This study was performed to measure the levels of iron stores from the total amounts of hemoglobin removed during iron reduction therapy. The C282Y and H63D mutations of HFE gene were analyzed in 94 patients. All of the patients were negative for C282Y mutation. One patient was homozygous, and 4 patients were heterozygous for H63D mutation. The body iron stores and iron restoration rate were measured in 59 patients in serial courses of iron reduction therapy. Mean values of body iron stores in the two groups with and without H63D mutation were 890 and 606 mg, while those of iron restoration rate were 1.85 and 1.52 mg/day, respectively. None of the indices of iron metabolism were different from the reference values measured similarly in healthy subjects, suggesting that the iron deposition in chronic hepatitis C is limited to the liver, probably due to changes in the iron distribution in tissues.
