Venesection or expectant management for moderate iron overload in HFE related hereditary haemochromatosis

血色病是一种可预防的遗传性铁超载疾病。未经治疗，它可以缩短生命，主要是由于肝硬化和癌症。它可以通过献血来预防，以维持正常的铁水平。然而，目前尚不清楚当个体体内铁含量中度升高时是否需要治疗。该研究项目将通过评估治疗和未治疗个体的一些扫描，问卷调查和血液测试来研究治疗对这一群体的影响。

Haemochromatosis is a preventable genetic iron overload disorder. Untreated, it can shorten life due mainly to liver cirrhosis and cancer. It can be prevented by blood donation to maintain normal iron levels. It is unclear, however, whether treatment is necessary when individuals have moderate elevation of iron in the body. This research project will study the effects of treatment in this group by assessing a number of scans, questionnaires and blood tests in treated and untreated individuals.
