Continuous Manual Exchange Transfusion for Patients with Sickle Cell Disease: An Efficient Method to Avoid Iron Overload
Published on: March 14, 2017
Dysmetabolic iron overload syndrome
Abstract:
Mild hyperferritinemia is frequent in patients with metabolic syndrome. When exceeding 500 pg/l, it usually accounts for real iron excess and is coined as dysmetabolic iron overload syndrome (DIOS). The diagnosis of DIOS is mainly made in middle-aged males. It relies upon the demonstration of hepatic iron overload by liver biopsy or MR. Iron excess is located not only within the liver but also within the spleen and visceral adipous tissue. Adipocytic iron is involved in maintaining or worsening insulin resistance. However, there is no definite proof of a short-term effect of iron removal by phlebotomy on glucose and insulin metabolism. Sustained modification of lifestyle and diet currently remains the only indisputable therapy in DIOS.
