Abstract
The aim of the research was
to study the effect of genetic predictors of thrombotic/ischemic events
in children with the developed complications and born mature or
premature. Material and methods. A prospective follow-up monitoring of
47 patients (inpatients of the State Novosibirsk Regional Clinical
Hospital) with thrombotic complications, the analysis of their medical
records were carried out. The homeostasis system parameters, carriage of
polymorphic variants of genes predisposing to thrombotic complications
were accomplished for the children during the follow-up period. Results
and discussion. Thrombotic and/or related ischemic events are more
common in premature infants, herewith the severe cerebral ischemia and
venous thrombosis localized in various vessels predominated over these
complications. The state of the blood coagulation system in children
with thrombotic/ischemic events is characterized by hypercoagulation
shifts in the external and internal cascades of blood coagulation and
accompanied by the increase in the D-dimers level. Among polymorphic
variants of genes of hemostasis system the occurrence of polymorphic
variant FV Leiden (rs6025) is higher in the study group compared to the
European population (χ2 = 7.454; p = 0.025). The obtained
data indicate the need for extended diagnostic studies of hemostasis
system and genetic search for «thrombogenic» predisposition in children,
especially premature, residing in intensive care units for the presence
of thrombotic readiness in order to timely predict the development of
possible thrombotic and ischemic complications.
