Description of intervention(s) / exposure
We are planning to carry out the scientific research in 4 stages.
First stage-maternity hospital (three months long). The first stage of study will be carried out at the maternity hospital. We will create special investigation history for women of each preterm and low birth weighing delivery. All information about pregnancy (health status, working rejime, family and living environment and ets.) and examination results of women will be fixed in maternal part of history. Physical exam outline and biomarker analysis results of each infant will be included to child part of history. It is planning to detect the level of following biomarkers, which are sensitive to injury of different organs and systems of fetus and specific proteins characterizing changes of pathologic reactions:
- markers of endothelial disfunction:endothelin-1, nitric oxide, endothelial nitric oxide synthase;
-adhesion molecules: soluble intracellular adhesion molecule -1, soluble vascular cellular adhesion molecule-1;
-apoptosis marker: caspasae 9.
The level of this markers will be detected in umbilical cord blood and peripheral blood of newborn infants in early neonatal period. Getting the umbilical cord blood is quite safe and nontraumatic for infants, because blood samples will be collected just after birth from placenta side of cord. Peripheral blood samples will not be collected for research, but from other analisis of maternity hospital or neonatal care unit (bilirubin fractions, intrauterine infectious and ets.).
Preterm babies will be categorised as less than 30 weeks of gestational age (including 30th week) and more than 30 weeks of gestational age. Intrauterine growth restricted babies will form the subgroup of each group.
Second stage – neonatal intensive care unit. This stage will last three months. We will add the diagnosis, examination results, all information about somatic and neural status to investigation history of infant transported from maternity hospital to neonatal intensive care unit.
Third stage - polyclinic. This stage will last approximately one year and six months. All infants discharged home from maternity hospital and from neonatal intensive care unit will be controled in polyclinic stage. We will contact directly to polyclinic doctors in appropriate polyclinic and contact to parents of children on telephone conversation. For more attentively control of changes in neurologic and somatic status we are planning personally control of each infant every six week. We will perform this control with our follow up team consisted of pediatrician, neurologist and child psychologist. We will add all information about neuro-somatic status of infants collecting from follow up team and also from polyclinic doctors and parents to investigation history of each infant.
Forth stage – statistical analysis of collecting materials and getting reliable results (six months long). We will find the statistical correlations and connects among different pregnancy factors, specific markers of umbilical cord and peripheral blood of infants and neuro-somatic status changes from neonatal till 3 year age of children. Statistical analysis will be realized by non-parametric and parametric methods.

Early detection / Screening
Comparator / control treatment
50 term healthy infants from normal pregnancies will be included to control group. In addition to special markers of research all the examination results (clinic and biochemical analisis, ultrasound and doppler results and etc.) performing in hospital will be fixed in investigation history of each infant.

Outcomes
Primary outcome [1] 286791 0
Detecting the correlations between the level of organ and endothelial disfunction markers (detected in umbilical cord blood and peripheral blood of infants in early neonatal period) and illness appearing till 3 year of age on the base of statistical analysis.
Timepoint [1] 286791 0
at three years after randomisation
Secondary outcome [1] 296663 0
Prognosing early age changes of neuro-somatic status on the background of detected perinatal risk factors and performing follow up control. Perinatal risk factors will be assesed on the base of maternal and neonatal health status referring to investigation history of every infant. The severity of hypoxic ischemic encephalopathy will be based on the Levene classification. Cranial ultrasound will be performed for all infants at the 2-nd and 6-th days of life with 5 and 7, 5 MHz vector transducers. The neurological assessment will be performed according to Dubowitz/Ballard scale during neonatal period. Behavior, motor and sensor development from 1-st month till 3-nd year of life will be assesed by DENVER II test.
