Materials and methods: researchers analyzed 54 cases of newborns of different gestational age (GA) that were in the ICU after birth due to severe condition; all newborns had combined hypoxic hemorrhagic brain lesion detected by neurosonography – periventricular leukomalacia (PVL) and intraventricular hemorrhage (IVH) of various severity. Catamnesis follow-up was performed up to 2–2,5 years of age. The control group consisted of 20 newborns, comparable in GA, body weight at birth, with an Apgar score of at least 6 points in the 1st minute of life and without changes in neurosonography. In the neonatal period, serum concentrations of S100, BDNF, VEGF, ALCAM, DR5 were studied in dynamics using the quantitative ELISA (Enzyme Linked Immuno Sorbent Assay) according to a standard protocol. Results: the concentration of factors contributing to destructive changes in tissues (S100, DR5, ALCAM) in the serum, was in inverse correlation with the level of VEGF and BDNF. The latter had a direct correlation relationship. VEGF directly correlated with CNTF by the end of the 2 nd week of life. Results of catamnesis follow-up: 43 children diagnosed with cerebral palsy, 25 with spastic diplegia, 18 with spastic tetraparesis, and 11 without evident motor disorders. In 28 children I–III level of motor disorders was determined according to GMFS, in 26 children – IV–V level. At the age of 2 years, all children underwent MRI of the brain and gliio-atrophic changes were detected. Significant differences in the implementation of neurological consequences were found between the number of children with grade I and II IVH and PVL and III–IV degree IVH and PVL. Conclusion: children with PVL and IVH III–IV degree have a high risk of severe neurological outcomes – spastic tetraparesis, impaired motor activity by GMFS IV–V level, mental retardation and symptomatic epilepsy.
