The condition characterized by increased body iron stores associated with components of MetS has been defined Dysmetabolic Iron Overload Syndrome (DIOS). DIOS represents the most frequent iron overload condition, since it is observed in 15% of patients with MetS and in half of those with NAFLD and its clinical presentation overlaps almost completely with that of dysmetabolic hyperferritinemia (DH). The pathogenetic mechanisms linking insulin resistance (IR), NAFLD and DIOS to iron overload are still debated. Hepcidin seems to play a role in iron accumulation in DIOS and NAFLD patients who show elevated serum hepcidin levels. Iron challenge does not restrain iron absorption despite adequate hepcidin production, suggesting that an impaired hepcidin activity rather than a deficit of hormone production underlies DIOS pathogenesis. Acquired and genetic factors are recognized to contribute to iron accumulation in NAFLD whereas additional studies are required to clearly demonstrate whether the same or different genetic factors lead to iron overload in DIOS. Finally, iron depletion by phlebotomy, together with modification of diet and life-style habits, represent the therapeutic approach to decrease metabolic alterations and liver enzymes in NAFLD and DIOS patients. In this review we summarized the current knowledge on the dysregulation of iron homeostasis in NAFLD and DIOS in the attempt to clarify whether they are different or more likely strictly related conditions, sharing the same pathogenic cause i.e. the MetS.
