Healthy Volunteers Clinical Trial
Official title:
Evaluation of Body Iron Stores in Overweight Healthy Volunteers
Normal body iron store value in overweight subjects is currently not described in literature. The comparison of this value with body iron levels in patients suffering from dysmetabolic iron overload syndrome (DIOS) could allow to quantify iron overload in this condition. The purpose of the study is to determine iron levels in healthy overweight volunteers, and to compare them to DIOS patients treated with phlebotomy.
Normal body iron store value in overweight subjects is currently not described in literature. The comparison of this value with body iron levels in patients suffering from dysmetabolic iron overload syndrome (DIOS) could allow to quantify iron overload in this condition. DIOS is the leading cause of hyperferritinemia and mainly affects men between 45 and 60 years. It is characterized by unexplained hyperferritinemia associated to metabolic disorders (including overweight) and iron overload, objectified by MRI or liver biopsy. Some authors suggest that hyperferritinemia associated to metabolic disorders is the expression of an inflammatory syndrome caused by insulin resistance and steatohepatitis, and not the manifestation of real iron overload. The debate surrounding iron overload in DIOS is related to the limits of the current analysis methods (phlebotomy, liver iron concentration, MRI). At present, phlebotomy is the standard method used to determine body iron stores. Using this method, the purpose of the study is to determine iron levels in healthy overweight volunteers, and to compare them to DIOS patients treated with phlebotomy included in another ongoing clinical trial (SAIGNEES - ClinicalTrials.gov Identifier: NCT01045525). ;
