Iron metabolism and lipid peroxidation products in infants with hypoxic ischemic encephalopathy

Abstract

Background:

Iron delocalization or misregulation of iron metabolism may play a critical role in the pathology of hypoxic ischemic encephalopathy (HIE).

Objective:

To study iron metabolism and lipid peroxidation in newborn infants and to correlate non-protein-bound iron (NPBI) concentration with the severity of the post-asphyxial injury and subsequent short-term outcomes.

Study Design:

Concentrations of NPBI and malondialdehyde (MDA) in the serum and in the cerebrospinal fluid (CSF) were measured in eight healthy newborn infants and nine newborn infants suffering from moderately severe HIE. Short-term outcomes (death, survival with or without neurological abnormality) were noted at hospital discharge.

Result:

Serum and CSF concentrations of both NPBI and MDA were significantly increased in HIE infants when compared to controls. Serum iron was significantly increased and total iron binding capacity was significantly decreased in HIE infants compared to controls. Out of the nine HIE infants, four infants died and two infants survived with abnormal neurological findings at hospital discharge. These six infants with clinical sequels had significantly increased concentrations of NPBI in the serum and in the CSF; and increased concentrations of MDA in the CSF when compared to the other three who survived without short-term abnormalities.

Conclusion:

We conclude that hypoxia ischemia alters iron metabolism and lipid peroxidation in newborn infants; and that NPBI and MDA in the CSF are increased in infants with HIE. This study supports a role for iron in oxidative injury to the central nervous system after hypoxic ischemic insults.
