Introduction: Human parvovirus B19 causes a wide range of complications in pregnant women including abortion, severe fetal anemia, non-immune hydrops fetalis, and even intrauterine fetal death. However, there is a dearth of information on the prevalence of the virus among pregnant women in southwestern Nigeria. Methodology: Blood samples were collected from 231 pregnant women and screened for antibodies to human parvovirus B19 IgM and IgG using an enzyme immunosorbent assay kits. Results: Of the 231 women, 31 were in their first trimester, 146 were in their second trimester, and 54 were in their third trimester. Forty-five (20%) were positive for parvovirus B19 IgG antibodies, 10 (4%) were positive for parvovirus B19 IgM antibodies, and 176 (76%) had no detectable parvovirus B19 antibodies. Twenty-eight (19%) of the 146 pregnant women in their second trimester were positive for parvovirus B19 IgG antibody while three (2%) of the 146 were positive for parvovirus B19 IgM antibody. Conclusions: It is evident that there is a high prevalence of human parvovirus B19 among pregnant women in south-western Nigeria. This suggests that there is an active transmission of the virus in the community; it is therefore necessary to conduct more studies on the virus in pregnant women in Nigeria to ascertain its effect on the fetus.

Introduction. Human parvovirus B19 is found worldwide. It causes various infections, including fifth disease (erythema infectiosum) in small children, acute arthropathy in adults, transient aplastic crisis and chronic anemia in immmunocompromised patients and even fetal infection, which may result in intrauterine fetal death or fetal hydrops. Many of these manifestations of B19 infection are caused by infection of erythroid precursor cells in bone marrow. Material and Methods. The aim of this paper was to establish the frequency of parvovirus B19 infection in the population of Vojvodina, as well as to indicate the significance of further investigations particularly in highly vulnerable population groups such as small children, pregnant women and immune deficient persons. A total of 244 serum samples of out- and in-patients of different age were analyzed using SERION ELISA classic parvovirus B19 IgG/IgM quantitative and qualitative tests for identification of specific antibodies against human parvovirus B19. Results. Acute infection was found in 35% of examinees, whereas parvoviurs B19 was identified in 32% of examined persons. Our tests results proved that 20% of examined pregnant women in our surroundings have acute HPB19 infection. At the same time, 45% of pregnant women have no specific antibodies, so they are at risk of infection during pregnancy. Acute infection was diagnosed in 41 children (43%): 22 samples (23%) were positive only to IgG antibodies and in 32 samples (34%) neither IgM nor IgG antibodies were identified. Acute infection was more frequently found in preschool children, i.e. in children aged 4 to 6 years (29%). Conclusion. In the absence of complete data on the frequency of particular diseases caused by this virus in our population, tests for human parvovirus B19 are strongly recommended.

Background: Human Parvovirus B19 (B19V) is a DNA virus, transmitted through respiratory secretions, hand-to-mouth-contact, blood transfusion and trans-placental transfer. It causes high mortality and morbidity in pregnant women, thus contributing to poor maternal and child health. B19V has been neglected due to dearth of epidemiological data. The aim of this study was to determine the sero-prevalence of Human Parvovirus B19 antibodies among pregnant women attending antenatal clinic at Federal Teaching Hospital Ido-Ekiti, Nigeria. Materials and Methods: This cross-sectional study enrolled pregnant women attending Federal Teaching Hospital Ido-Ekiti from January to May 2019 to obtain sero-epidemiological data. One hundred and twenty-two (122) consenting pregnant women were enrolled following institutional ethical approval. They were administered structured questionnaire and venous blood was collected in plain tubes for serum extraction. Sera samples were analyzed for IgG and IgM antibodies using the enzyme linked immunosorbent assay method. Percentages, median, chi-square and multivariate analysis were carried out using SPSS version 17. Results: The prevalence of IgG was 44.3% (54/122), IgM 41.8% (51/122), and IgG/IgM 28.7% (35/122) leaving 55.7% (68/122) of the population uninfected. The median age of participants was 22 (Interquartile range 18-25) years among which 36-45years had the highest prevalence which was not statistically significant (p=0.09 4.75). There was association between miscarriage, still birth, history of blood transfusion and prevalence of Human Parvovirus B19 (p<0.05). Conclusion: There is a high Prevalence of B19V among pregnant women attending antenatal clinic in this study. This underscores the need for testing and immunization of pregnant women against B19V.

Abstract Objective: This study aims to determine whether it is possible to predict preeclampsia by comparing postpartum results and test results of the pregnant women diagnosed with preeclampsia, whose first and/or second trimester screening tests were accessible, and to demonstrate the predictability of severity and week of onset.Background: 204 patients underwent renal transplantation in our center and 84 of them were female. Five of our patients (one of them had two births) gave birth to a total of 6 pregnancies.Method: 135 patients were diagnosed with preeclampsia and their first and/or second trimester screening tests were accessible, and 366 control participants gave birth to a healthy baby between 37-41 weeks after standard follow-up period for pregnancy and their screening tests were also accessible.Results: The study results show that the first trimester maternal serum PAPP-A level is significantly low in preeclamptic pregnant women, and that the second trimester maternal serum AFP and hCG levels are significantly high and uE3 levels are significantly low The results also suggest that the first and second trimester Down syndrome biochemical markers can be used in preeclampsia screening.Conclusion: Among these markers, uE3 is the parameter which affects the possibility of preeclampsia the most. However, the first and second trimester Down syndrome biochemical markers are not effective in predicting the severity and onset week of preeclampsia.

AbstractThyroid function tests are frequently assessed during pregnancy to evaluate thyroid dysfunction or to monitor pre-existing thyroid disease. However, using non-pregnant reference intervals can lead to misclassification. International guidelines recommended that institutions should calculate their own pregnancy-specific reference intervals for free thyroxine (FT4), free triiodothyronine (FT3) and thyroid-stimulating hormone (TSH). The objective of this study is to establish gestation-specific reference intervals (GRIs) for thyroid function tests in pregnant Turkish women and to compare these with the age-matched non-pregnant women.Serum samples were collected from 220 non-pregnant women (age: 18–48), and 2460 pregnant women (age: 18–45) with 945 (39%) in the first trimester, 1120 (45%) in the second trimester, and 395 (16%) in the third trimester. TSH, FT4 and FT3 were measured using the Abbott Architect i2000SR analyzer.GRIs of TSH, FT4 and FT3 for first trimester pregnancies were 0.49–2.33 mIU/L, 10.30–18.11 pmol/L and 3.80–5.81 pmol/L, respectively. GRIs for second trimester pregnancies were 0.51–3.44 mIU/L, 10.30–18.15 pmol/L and 3.69–5.90 pmol/L. GRIs for third trimester pregnancies were 0.58–4.31 mIU/L, 10.30–17.89 pmol/L and 3.67–5.81 pmol/L. GRIs for TSH, FT4 and FT3 were different from non-pregnant normal reference intervals.TSH levels showed an increasing trend from the first trimester to the third trimester, whereas both FT4 and FT3 levels were uniform throughout gestation. GRIs may help in the diagnosis and appropriate management of thyroid dysfunction during pregnancy which will prevent both maternal and fetal complications.

ABSTRACT Using tritium-labelled oxytocin with a high specific activity, the halflife in the blood and the urinary excretion of intravenously injected oxytocin were followed in the female. The following groups of patients were studied: normally menstruating women during different phases of the menstrual cycle, women using a combination of gestagenic and oestrogenic hormones for oral contraception, and pregnant women in the first and second trimester. The pregnant women were admitted to the hospital for legal abortion in the 10th–20th week of gestation. In the proliferative phase, t½ was 272 seconds (n = 14), in the secretory phase 221 seconds (n = 5), and in women using oral contraceptives 199 seconds (n = 10). In pregnant women during the first trimester, t½ was 178 seconds (n = 6). The corresponding value in women examined during the 14th–17th weeks and during the 18th–20th weeks of gestation was 295 seconds (n = 6) and 282 seconds (n = 6), respectively. T½ was also determined within 24 h of abortion in patients in the second trimester, where the abortion was induced by intra-amniotic instillation of 50% glucose. In all cases a decrease in t½ was found. The decrease was most marked in women during the 18th–20th weeks of gestation. Altogether 25–50% of the radioactivity injected was recovered in the urine from pregnant women within 3 h of the injection. Thin-layer chromatography of the urine did not reveal the presence of any intact oxytocin. The results demonstrate that the disappearance of oxytocin from the blood seems to be influenced by the sex hormones. Thus, an oestrogendominated stage shows a lower disappearance rate, whereas gestagens produce the reverse effect. The pronounced decrease in t½ in pregnant women immediately after abortion might be due to a change to a more progesterone-dominated stage induced by the death of the foetus, or by an alteration in the affinity of oxytocin to the myometrium.
