title: [8-oxo-7,8-dihydro-2'-deoxyguanosine as a marker of DNA oxidative stress in individuals with combined familiar hyperlipidemia].
abstract: OBJECTIVE
  To compare 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxo-dG) value as an indicator of oxidative stress situation between healthy and familial combined hyperlipidemic (FCH) subjects as a mixed dislipidemia with insulin resistance model and early coronary heart disease, and to study its relationship with clinical-biologic parameters of insulin resistance.
  
  
  METHODS
  40 non-related FCH patients (15 women) and 20 normolipidemic and nondiabetic healthy subjects (8 women) were studied. Clinical, anthropometric and biochemical parameters (lipidic profile, glucemia, insulinemia and 8-oxo-dG) were measured in fasting state in all.
  
  
  RESULTS
  Both groups had similar age, body mass index blood pressure and waist perimeter values. Insulin and 8-oxo-dG values were significantly higher in FHC subjects. These differences were maintained after correcting by waist perimeter. 8-oxo-dG correlated positively with insulin and trygliceride; and negatively with high density lipoprotein cholesterol in FCH subjects.
  
  
  CONCLUSIONS
  Insulin values are independently correlated with oxidative stress degree measured as 8-oxo-dG.
