Herpesvirus infection is associated with an increase of LPO and of the membrane lipid and lipid-protein layers microviscosity in erythrocyte membranes of pregnant patients. This results in modification of the erythrocyte stromal protein composition. Erythrocyte deformability increases sharply under these conditions, this leading to disorders in tissue metabolism in the organs of pregnant patients.
The goal of this research was to evaluate seropositivity to HSV-1 among pregnant women and its effect on the course of pregnancy, childbirth and the condition of newborns. Methods: The serological status, socio-demographic characteristics, parity of pregnancy and childbirth and condition of newborns in women seronegative and seropositive to HSV-1 with recurrent infection and its latent course during pregnancy were analyzed. Newborns from these mothers made up the corresponding groups. Results: Low titers of IgG antibodies to HSV-1 in women in the first trimester of pregnancy are associated with threatened miscarriage, anemia in pregnancy and chronic placental insufficiency. High titers of IgG antibodies to HSV-1 in women in the second trimester of pregnancy are associated with late miscarriages and premature births, anemia in pregnancy, chronic placental insufficiency, labor anomalies, early neonatal complications (cerebral ischemia, respiratory distress syndrome) and localized skin rashes. Low titers of IgG antibodies to HSV-1 in women in the third trimester of pregnancy are associated with premature birth, anemia in pregnancy, chronic placental insufficiency, endometritis, complications of the early neonatal period and localized skin rashes. Conclusions: Our research showed that low or high titers of IgG antibodies to HSV-1, determined by the timing of recurrence of infection during pregnancy, are associated with a high incidence of somatic pathology and complications in pregnancy, childbirth and the neonatal period.
The aim of the study was to assess free radical processes and their effect on oxygenation of hemoglobin in the blood of 18-21 weeks pregnant women with exacerbation of cytomegalovirus infection. We examined 40 pregnant women with exacerbation of cytomegalovirus infection and various levels of specific antibodies (IgM) at 18-21 weeks and 30 pregnant women without cytomegalovirus. The spectrophotometric method was used to determine the content of oxyhemoglobin, methemoglobin, thiobarbituric acid (TBA)-active products, superoxide dismutase in blood erythrocytes; thin layer chromatography – phosphotidylcholine, lysophosphatidylcholine; gas-liquid chromatography – arachidonic acid. Exacerbation of cytomegalovirus infection changes the activity of free radical oxidation processes, the severity of which is determined by the level of IgM antibodies and is manifested by a decrease in superoxide dismutase (p = 0.000) and phosphatidylcholine (p = 0.000), an increase in phospholipase A2 (p = 0.000), lysophosphatidylcholine (p = 0.000), arachidonic acid (p = 0.000) and TBA-active products (p = 0.000). Accumulation of superoxide anion radical and products of lipoperoxidation in erythrocytes decreases oxyhemoglobin (p = 0.000) and increases methemoglobin (p = 0.000). Exacerbation of cytomegalovirus infection at 18-21 weeks is associated with the enhancement of free radical lipid oxidation and a deficiency in the antioxidant activity of superoxide dismutase. It decreases oxygen transport properties and increases phagocytosis by red blood monocytes; and pregnant women develop further hemic hypoxia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
