ABSTRACT
<p><b>OBJECTIVE</b>To study the serum levels of insulin-like growth factor I(IGF-I)and growth hormone (GH) in neonates with hypoxic-ischemic encephalopathy (HIE) and to investigate the relationship of serum levels of IGF-I and GH with the severity of HIE.</p><p><b>METHODS</b>Serum levels of IGF-I and GH were measured within 72 hrs (acute stage) and on the 26-28th days (convalescence stage) of life in 53 HIE neonates. There were 30 babies in the mild HIE group, 15 babies in the moderate HIE group, and 9 babies in the severe HIE group. Thirty normal newborns were used as the control group. Neonatal behavioral neurological assessment (NBNA) was performed on HIE neonates at the acute and convalescence stages.</p><p><b>RESULTS</b>The IGF-I levels of the mild, moderate and severe HIE groups measured within 72 hrs of life were 59.65 +/- 29.61, 33.56 +/- 17.32, and 23.58 +/- 13.57 ng/mL respectively and those of the three HIE subgroups on the 26-28th days after birth were 89.26 +/- 48.65, 71.46 +/- 38.35, and 54.39 +/- 26.39 ng/mL respectively. The serum IGF-I levels of HIE neonates at both acute and convalescence stages were significantly lower than those of the control group (71.23 +/- 35.42 and 96.54 +/- 52.38 ng/mL respectively; both P < 0.01), and associated with the severity of HIE as well as NBNA scores. GH levels were not significantly correlated to the severity of HIE and NBNA scores.</p><p><b>CONCLUSIONS</b>Serum IGF-I levels can be used as a marker for estimating the severity and the outcome of neonatal HIE.</p>
