title: [Dysmetabolic hepatosiderosis, characteristics in 51 patients].
abstract: OBJECTIVE
  Dysmetabolic hepatosiderosis is a recently described entity, which reunites iron overloads associated with polymetabolic syndromes, steatosis and steato-hepatitis. The aim of this study was to specify the relationship between iron overload, polymetabolic syndrome, HFE mutations of primary hemochromatosis and steatosis.
  
  
  METHODS
  This was a 5-year retrospective study of 51 patients hospitalised and/or seen in consultation, non-alcoholic, presenting with hyperferritinemia associated with a polymetabolic syndrome and/or hepatic steatosis.
  
  
  RESULTS
  Patients mean age was of 53 +/- 12 years with a sex ratio M/F of 5.4. Metabolic disorders were found in 97% of the non-steatosis patients (overweight: 40%, perturbed sugar metabolism: 47%, dyslipidemia: 79.5%). Hyperferritinemia was constant but moderate (513.4 +/- 280.3 ng/ml). Transferrin saturation was predominantly normal (0.44 +/- 0.17). The hepatic enzymes were normal or only slightly perturbed. Steatosis was revealed by sonography in 62% of cases. The hepatic iron overload, documented in 6 patients by hepatic needle biopsy, was discreet (concentration/age ratio of 1.64 +/- 0.19). Among the 59% patients screened for the HFE gene, 40% were positive for C282Y and/or H63D. There was no correlation between ferritin levels and iron parameters, polymetabolic syndrome parameters and hepatic enzymes. The HFE mutations had no influence on the iron parameters.
  
  
  CONCLUSIONS
  Dysmetabolic hepatosiderosis must be know by hospital practitioners because of their prevalence in cases of hyperferritinemia and their therapeutic incidence.
