Objective: The aim of this work was to investigate the correlation between dynamic changes of serum insulin-like growth factor 1 (IGF-1), growth hormone (GH), neuroglobin (NGB), and neonatal behavioral neurological assessment (NBNA) scores in different periods in neonates with hypoxic ischemic encephalopathy (HIE).
Patients and methods: Sixty HIE patients in the Neonatal Department of our hospital were selected. They were divided into the mild group (35 cases), moderate group (19 cases), and severe group (six cases) according to the diagnostic criteria. During the same period, 18 neonatal patients born at term in our hospital were chosen as the control group. Data were analyzed by SPSS19.0 statistical software (SPSS Inc., Chicago, IL, USA). The dynamic changes of IGF-1, GH, and NGB in different periods, as well as NBNA scores in HIE patients and in the control group, were analyzed. Furthermore, we analyzed the degree of correlation of IGF-1, GH, and NGB in different periods as well as NBNA scores in HIE patients and in the control group.
Results: 1- IGF-1 levels between the three groups of HIE patients and control group had significant differences (p<0.05); 2- Comparing GH levels between the HIE experimental groups and control group, there was no statistical significance; 3-Comparing serum NGB levels between the three HIE experimental groups and control group, there were significant differences (p<0.05); 4- Comparing NBNA scores of the three groups of HIE patients and control group, there was a significant difference between the mild group and control group; 5- Serum IGF-1 and NBNA scores were positively correlated in the acute and recovery phase, while NGB level and NBNA scores were negatively correlated in the acute and recovery phase (p<0.05), which had statistical significance.
Conclusions: In neonatal HIE, serum IGF-1, GH, and NGB levels change. IGF-1 and NGB levels correlate with the prognosis of HIE.
