title: [Behavior of thiobarbituric acid reactive substances, alpha-tocopherol, glutathione and selenium during hypertension in pregnancy].
abstract: METHODS
  In a longitudinal study the changes of serum or plasma levels of TBARS, alpha-tocopherol, glutathione and selenium were investigated comparing 46 pregnant women with hypertensive syndrome and 18 women with normal pregnancies.
  
  
  CONCLUSIONS
  A significant increase in TBARS serum level was found in women suffering from hypertension. There was no correlation between the severity of hypertension and the extent of the TBARS rise. An absolute deficiency of the antioxidants alpha-tocopherol, glutathione and the elements selenium, calcium, magnesium, iron and zinc as a cause or a consequence of hypertension in pregnancy could be excluded. Low serum levels of copper and selenium could decrease the activity of glutathione peroxidase (Gpx) resulting in higher levels of TBARS and glutathione during the last trimester of pregnancy and delivery. Increased concentrations of iron in women with hypertensive syndrome may affect the formation of lipid peroxides. The outcome of children was unaffected by increased lipid peroxide levels when an antihypertensive therapy was consequently performed.
