The study aimed to determine the incidence of congenital infection by Toxoplasma gondii and to describe neonatal and maternal characteristics regarding newborn infants treated at a teaching hospital in the town of Passo Fundo, State of Rio Grande do Sul, Brazil. Cord blood samples collected from 1,250 live newborns were analyzed. The laboratory diagnosis was established by the detection of Toxoplasma gondii IgM using an enzyme linked fluorescent assay. Gestational age, intrauterine growth, anthropometric measures, and prenatal characteristics were assessed. The incidence of congenital toxoplasmosis at birth was 8/10,000 (95%CI 0.2-44.5). Mean birthweight was 3,080 ± 215.56 grams and mean gestational age was 38.43 ± 1.88 weeks. With regard to prenatal care, 58% of the pregnant patients visited their doctors five times or more and 38.9% were serologically tested for toxoplasmosis in the first trimester of pregnancy. The incidence of congenital toxoplasmosis was similar to that found in most studies conducted in our country and abroad. Our study sample is representative of the town of Passo Fundo and therefore it is possible to consider the frequency observed as the prevalence of the disease in this town during the study period.

Background: Toxoplasma Gondii, Rubella, and Cytomegalovirus (CMV) are the most common causes of congenital infections worldwide. There is not a consensus on these infectious agents should be screened during pregnancy. The aim of this study is to determine the prevalence of toxoplasma, rubella, and CMV infections in order to know the need for antenatal screening.Methods: This retrospective cross-sectional study was performed on 1309 ambulatory pregnant patients who applied to the obstetric clinic of a university hospital between October 2016 and April 2018. Documents of patients in the first trimester were reviewed and serologic data of Toxoplasma gondii, CMV, Rubella infections were retrieved from the computer database.Results: Of 1309 pregnant women, positivity for anti-Toxoplasma IgG antibody was 352(26.9%), while 17(1.3%) of the subjects tested were positive for the anti-Toxoplasma IgM antibody. These positivities of the pregnant women for anti-Rubella IgG and IgM were 1147(87.6%) and (0.1%), respectively. These positivities of the pregnant women for anti-CMV IgG and IgM were 1163(88.8%) and 17(1.3%), respectively.Conclusions: We detected high rates of immunity against Rubella and CMV but low rates of immunity against Toxoplasma in this retrospective cohort of pregnant women. Due to high rates of seropositivity against Rubella and CMV, routine nationwide screening may not be necessary.

The paper presents a case of a boy who developed the symptoms of congenital toxoplasmosis: hydrocephalus, retinitis, choroiditis and intracranial calcifications (the Sabin–Pinkerton triad). Despite prenatal screening in the first trimester of pregnancy (in accordance with the guidelines of the Ministry of Health), which indicated the diagnosis of asymptomatic primary Toxoplasma gondii infection in the pregnant mother, no antiparasitic therapy was used. The presented serological and imaging findings, as well as specialist consultations confirm the intensified effects of congenital infection in the child. Although the child was put on anti-toxoplasma therapy immediately after birth, he developed severe psychophysical development disorders. The paper discusses recommendations for maternal diagnosis and antiparasitic treatment that could have prevented the full-blown congenital toxoplasmosis in the described patient.

The aim of the work is to assess the effects of cytomegalovirus infection on the 20α-hydroxysteroid dehydrogenase activity in the villous chorion syncytiotrophoblast in the first trimester of pregnancy. The materials for the study included 48 villous chorions samples taken during spontaneous abortions at 8th–10th weeks of gestation from women with reactivation of cytomegalovirus infection (the main group). The control group included 35 villous chorions samples from pregnant women with chronic cytomegalovirus infection in the latent stage taken at medical abortions at the same stage of gestation. The results of women’s examination were studied taken into account the activity of cytomegalovirus infection by immunoassay by detection of IgM antibodies or by 4 times and more increase of IgG antibody titers in the paired serums in dynamics in 10 days. The activity of 20α-hydroxysteroid dehydrogenase was assessed by the histochemical method. Quantitative evaluation of the reaction products was carried out on sections under the microscope MT (Japan) connected to software-hardware complex «SCION Corporation» (USA). At histochemical specimen of villous chorion of pregnant women who had a reactivation of cytomegalovirus infection during pregnancy (main group), there was a decrease of cytophotometric parameter of 20α-hydroxysteroid dehydrogenase activity till 30.1±2.12 pixels/μm2 (p<0.001) compared with the control group. The decrease in the reaction activity in syncytiotrophoblast indicated a decrease in the contents of 20α-dihydroprogesterone in placenta, which contributed, in our opinion, to spontaneous abortion.

The aim is to study the features of changes of free-radical status, antioxidant protection and morphologic changes of erythrocytes of the peripheral blood of pregnant women of the first trimester with exacerbation of cytomegalovirus infection (CMVI). 35 pregnant women with exacerbation of CMVI in the first trimester of gestation (the main group) and 35 pregnant women without this pathology of the same age and term as the patients of the main group were examined. Erythrocytes of the venous blood stabilized by heparine as well as blood plasma became the material of the study. There has been studied the condition of lipid peroxidation (LP) by the contents of diene conjugates and active products reacting with thiobarbituric acid; the state of nonenzymatic antioxidant protection by the contents of α-tocopherol as well as of the enzyme of erythrocytes (superoxide dismutase); morphologic changes of erythrocytes. It was found out that the exacerbation of CMVI in the first trimester of pregnancy is associated with activation of LP processes which include modification of not only primary, reverse stages of this process – the increase of the concentration of diene conjugates (p<0.001), but they lead to an increased formation of secondary active products reacting with thiobarbituric acid (p<0.001), intensifying the destructive action on the membrane of erythrocytes. Primary and secondary products of LP against the decrease of concentration of erythrocyte superoxide dismutase (p<0.001) and α-tocopherol (p<0.001) are accumulated in increasing concentrations and become potential factors of erythrocytes damage causing their functional and metabolic inferiority. Metabolic disturbances and damages of cellular membranes lead to the increase of population of echinocytes, target-like and degenerative forms of erythrocytes, which can be accompanied by a high probability of intravascular hemolysis and contribute to the development of hemic hypoxia complicating the infectious process and the course of pregnancy. Within the present hyperoxidation and suppression of antioxidant protection that lead to the worsening of the rheology of blood, women with exacerbation of CMVI in the first trimester of pregnancy should be prescribed the medicine stabilizing the lipid exchange.

Introduction. It is now generally acknowledged that cytomegalovirus infection (CMVI) is one of the main causes of miscarriage. However, the mechanism of this effect has not been sufficiently studied. At the same time, the influence of acids of the ɷ-3 family and α-tocopherol (αTP) on the placentation process through a pro-angiogenic action is shown.Aim. To study the concentration of αTP and ɷ-3 family acids in the peripheral blood and establish their role in miscarriage in CMV-seropositive women with CMVI reactivation.Materials and methods. A case-control study included 64 women in the first trimester of pregnancy (7-10 weeks), of which 36 were CMV-seropositive with CMVI reactivation (main group) and 28 were CMV-seronegative (control group). CMVI was diagnosed by the determination of class M and G antibodies by ELISA, as well as CMV DNA detected by PCR. The concentration of ɷ-3 acids of the family (eicosapentaenoic – EPA, docosahexaenoic – DHA) in blood serum was studied by capillary gas-liquid chromatography (J.P.Carreau, J.P.Dubacq). The αTP concentration was determined by the fluorometric method (L.G.Hansen, W.I.Warwich).Results. In women of the main group, a significant (p<0.001) decrease in the concentration of αTP to 1.32±0.025 μg/mL was observed in the peripheral blood compared to the same indicator in the control group (1.49±0.029 μg/mL). At the same time, the levels of EPA and DHA were also statistically significant (p<0.001) lower than the same indicator in the control group and amounted to 1.09±0.012 and 6.09±0.015%, respectively (in the control, 1.29±0.071 and 8.80±0.071%, respectively). Conclusion. The obtained results of the study allow us to establish the important role of disorders in the content of α-TF, EPA and DHA in the pathogenesis of miscarriage during reactivation of CMVI in the early periods of gestation, which can serve as a basis for expanding diagnostic and therapeutic measures in this pathology of pregnant women.
