ПАТОФИЗИОЛОГИЧЕСКИЕ МЕХАНИЗМЫ ПОВРЕЖДАЮЩЕГО ДЕЙСТВИЯ ЦИТОМЕГАЛОВИРУСНОЙ ИНФЕКЦИИ ПРИ БЕРЕМЕННОСТИ

Abstract

This systematic review was undertaken to define the urgency of studying the problem of cytomegalovirus infection due to the high frequency of detection of specific antibodies among women of childbearing age and the negative consequences of cytomegalovirus for the fetus and newborn. Despite the advances in modern medicine in the study of etiopathogenesis and diagnosis of cytomegalovirus infection during pregnancy, there is currently no trend towards a reduction in the incidence of obstetric pathologies and fetal damage. Physiological features of the functioning of the immune system in pregnancy are discussed; they create the prerequisites for the emergence or activation of long time persistent cytomegalovirus infection and intrauterine fetal damage. Complications in newborns are much more common if the primary cytomegalovirus infection was detected in the first trimester of pregnancy. Cytomegalovirus infection is accompanied by the development of immunodeficiency, but pathophysiological mechanisms of cytomegalovirus infection with the damaging effect in the first trimester of pregnancy need to be detailed. The pathophysiological mechanism of mismatch of immune regulation in pathological pregnancy and in the presence of cytomegalovirus infection is Th-1/Th-2 imbalance which can serve as a target for the development of pathogenetically oriented therapy of pregnant women with cytomegalovirus infection. It is suggested that the specification of these mechanisms will reduce the frequency of obstetric pathologies.
