What's Important and New in Hemochromatosis?

Abstract

Major advances in the understanding of genetic iron overload have led to a clarification of the nosology and terminology of the related diseases. The term hemochromatosis should be reserved to the entities where iron overload is related to hepcidin deficiency or hepcidin resistance. The diagnosis of hemochromatosis is non-invasive, based on clinical examination, blood investigations and, whenever possible, magnetic resonance imaging. Phlebotomies remain the mainstay of the treatment, but new therapeutic approaches should, in the future, constitute a valuable advance, hopefully both as an adjunct to bleeding in the induction phase and as its replacement in the maintenance phase. The goal of the present review is to update the terminology of hemochromatosis in light of major pathophysiological advances, and the main features of its diagnostic and therapeutic approaches.
