Objectives: The human placenta is the nourishing reservoir for the sustenance of the fetus and synthesizes a growth-stimulating hormone to enhance proper growth and maturation. The size or thickness of the placenta enlarges as the pregnancy progresses in age to attain a favorable state which can cope with the increasing fetal demands. Placental thickness (PT) is a reflector of fetal well-being, and it is related to fetal weight making it necessary to assess the influence of pregnancy-induced hypertension (PIH), a common pathology in pregnancy, on the placental size or thickness. The main objective of this research is to compare and evaluate the PT and fetal weight in PIH and normotensive pregnant women. Material and Methods: The study was a prospective cross-sectional case-controlled study done in the Radiology Department of the University of Calabar Teaching Hospital. During a 12 months study period, 200 singleton pregnant women (consisting of 100 pregnancy-induced hypertensives and 100 normotensive pregnant women) of between 20 and 40 weeks of gestation were enrolled in this study. The two groups were gestational age-matched. The PT was measured trans-abdominally using an ultrasound scan. Pearson’s correlation analysis was used to establish the degree of relationship between PT and other fetal anthropometric and maternal parameters. Results: PT was significantly lower in pregnancy-induced hypertensives than in the controls (28.95 ± 5.71 mm vs. 32.31 ± 5.47 mm, P = 0.000). There was a significant negative correlation between the PT and the degree of proteinuria (P = 0.011). Conversely, a significant positive correlation existed between PT and estimated gestational age (P = 0.000) and also estimated fetal weight (EFW) (P = 0.000), in both groups. This same relationship was observed between the body mass index and PT (P = 0.007) as well as the EFW (P = 0.002) in the control group. The mean EFW in pregnancy-induced hypertensives (2.23 ± 1.07 kg) was higher than in the controls (2.13 ± 1.03 kg), but the difference was not significant (P = 0.505). Conclusion: There was a reduction in the PT in PIH, which may be due to the appearance of proteinuria when the blood pressure was elevated. However, we did not observe the expected reduction in the EFW due to a reduction in PT, which usually results from proteinuria.

Abstract. The role of a high CRH level in normal pregnancy remains unknown. Therefore we evaluated the concentrations of CRH and the related hormones in patients with pregnancy-induced hypertension. Fourteen women with pregnancy-induced hypertension, aged 20-39, at 30-39 gestational week, were investigated. The control group consisted of 20 healthy pregnant women matched according to gestational age. Plasma CRH, β-endorphin-like immunoreactivity, cortisol, and human placental lactogen were measured by radioimmunoassay, ACTH by an immunoradiometric method. It was found that in hypertensive patients the mean CRH concentration was significantly higher (4257±840 (sem) ng/l) than that in healthy pregnant women (1083±227 ng/l, p<0.001). The concentration of ACTH, however, was only slightly higher 65.0±6.0 vs 50.7±2.5 ng/l, p<0.025, whereas the differences in β-endorphin, cortisol and human placental lactogen were not significant. In both groups there was no correlation between the CRH level and those of the related hormones. In healthy pregnant women the CRH level closely correlated with gestational age (r=0.76, p<0.001), whereas in patients with hypertension no such correlation was present (r=0.29). We assume that the marked enhancement of plasma CRH in pregnancy-induced hypertension is probably caused by its decreased breakdown in ischemic placental tissue, but its increased synthesis in the placenta and its indirect counterregulatory hypotensive role must also be considered.

Abstract Background. It is of great public health significance to monitor the global meiosis mother-to-child transmission plan proposed by WHO and monitor the prevalence of maternal syphilis and the factors affecting mother-to-child transmission. Methods. We collected 271 medical records of prenatally diagnosed (from 87286 pregnant women) of syphilis among pregnant women a maternity hospital in Jilin Province China from 2013 to 2017. The chi-square test and Logistic multiple regression analysis were used to describe the clinical characteristics of pregnant women with syphilis and the related factors of adverse pregnancy outcome. Results. The average prevalence of maternal syphilis is 0.31% (95%[CI]: 0.27%-0.35%). The mean age of 271 pregnant women with syphilis is 27.62±5.4 years old. The maternal syphilis prevalence of absence of paid occupation is 73.8%; rural population accounts for 43.6%. Maternal women with a history of abortion accounted for 43.1%, of which 53.1% had abortion ≥2; The average rate of treatment in pregnancy is 25.5% (95%[CI]: 25.4%-25.6%). The prevalence rate of APOs are 43.9% (95%[CI]: 38.1%-49.9%), declined in five years (P<0.05). APOs was significantly higher in women at 30–34 age group than that in 0-24 age group (OR= 2.916, 95%CI: 1.298-6.549) and higher in Un-treatment in pregnancy than that in receive treatment (OR=2.469, 95%CI:1.225-4.975). PROM occurrence (OR=2.702, 95%CI:1.219-5.988); CRP elevation (≥10 mg/L) and RPR high titer (≥1:8) are related to the occurrence of APOs. Abortion, prematurity and low birth weight are associated with no treatment during pregnancy (P<0.05). Comparison of 42 cases of pregnancy-induced hypertension and non-pregnancy-induced hypertension, Dysmenorrhea (OR= 3.654, 95%CI:1.812-7.369) and elevated urine protein (OR= 2.259, 95%CI:1.161-4.394) are the influencing factors of maternal syphilis complicated with pregnancy-induced hypertension. Conclusions. The prevalence of maternal syphilis in northern China is lower than that of 10 years ago, but the decline is still lower than that in the economically developed regions of the south. The rate of non-treatment of syphilis during pregnancy is high, and should be alert to the rebound of maternal syphilis.

Introduction: Hypertensive disorders complicate 5-10% in all pregnant and together form the deadly triad and hemorrhage and heart disease that contribute greatly to maternal morbidity or mortality. This study aims to identify retinal changes in pregnancy-induced hypertension and analyze the association between retinal changes and hypertension severity. Method: A total of 100 pregnant admitted with pregnancy-induced hypertension(PIH) were included. Patients with pre-existing hypertension, diabetes mellitus, and renal diseases were excluded from the study. The vision, anterior segment, and Fundus were examined. Result: Higher number of PIH were recorded in the 21-30 years age group. Fifty-four pregnant women suffered from mild preeclampsia, 40 pregnant women with severe preeclampsia, and six pregnant women with eclampsia with seizures. 41% of pregnant had normal fundus, and 24% of pregnant had hypertensive retinopathy. Whereas grade 2,3, and 4 retinopathy was observed in 22%, 6%, and 2% of pregnant women. Two percent of pregnants had macular edema, and 3% had central serous retinopathy. No association was observed between the fundus findings with age/gravida. Whereas a significant positive correlation was observed between the fundus findings and hypertension severity (P < 0.001). Conclusion: Overall, 54% of pregnants were recorded with hypertensive retinopathy. A positive correlation was observed between fundus changes with the hypertension severity. This study reports the importance of routine fundus examination in pregnant with hypertension. Retinal change during pregnancy is an important indicator to decide the pregnancy termination or any other opt.

The pathophysiology of pregnancy-induced hypertension and preeclampsia may involve abnormalities in placentation and the Fas/Fas ligand system. Hypothesizing abnormal plasma Fas and Fas ligand in pregnancy-induced hypertension, we recruited 20 hypertensive pregnant women at mean week 15 and 29 at week 30: 18 were studied at both time points. Control groups were 20 normotensive pregnant women at week 20, 29 women at week 27, and 50 nonpregnant women. sFas and sFas ligand (sFasL) were measured by enzyme-linked immunosorbent assay (ELISA). The hypertensive women had lower sFasL at both stages of their pregnancy ( P < .05). There were no differences in sFas. In 18 hypertensive pregnant women, sFasL fell from week 15 to week 29 ( P < .03). We conclude that sFas and sFasL is unchanged in normal pregnancy. Hypertension in pregnancy is characterized by low sFasL, and levels fall from weeks 15 to 29. This may reflect differences in placentation in the differing physiological and pathological states.

1. Platelet-activating factor is a phospholipid with potent vasodilator and platelet-activating properties. To test the hypothesis that a generalized change in cellular platelet-activating factor metabolism may be involved in the systemic vasodilatation of normal pregnancy or pregnancy-induced hypertension, we studied platelet-activating factor and eicosanoid synthesis in isolated leucocytes obtained from pregnant women before and after delivery compared with age-matched non-pregnant control subjects. Parallel observations were carried out in age- and gestation-matched women with uncomplicated hypertension in pregnancy and in women with pregnancy-induced hypertension and a further set of normotensive pregnant control subjects. 2. Leucocyte counts were higher in all pregnant groups compared with non-pregnant control subjects. Neutrophil production of platelet-activating factor and metabolites of prostacyclin, prostaglandin E2 and thromboxane in response to calcium ionophore stimulation were all lower in pregnant women compared with non-pregnant control subjects, but returned to similar levels 6 weeks post partum. There was no significant difference between essential hypertensive and normotensive groups. When women with pregnancy-induced hypertension were a priori subdivided into those with or without proteinuria, subjects with proteinuria showed significantly lower levels of neutrophil platelet-activating factor synthesis. 3. Plasma levels of the platelet-activating factor metabolite (lyso-platelet-activating factor) were also lower in pregnancy, suggesting alterations in the activity of enzymes controlling synthesis or degradation of this phospholipid in pregnancy. In pregnancy-induced hypertension the levels of plasma lyso-platelet-activating factor were higher than in normal pregnancy. 4. Thus this study demonstrates a reduction in the maximum capacity of neutrophils to synthesize platelet-activating factor and the three main classes of eicosanoids in vitro and a reduction in plasma lyso-platelet-activating factor levels in normotensive and essential hypertensive pregnancies. Contrary to expectation neutrophil prostacyclin metabolite generation was reduced in normal pregnancy. In pregnancy-induced hypertension with proteinuria the suppression of neutrophil platelet-activating factor synthesis was more pronounced. The results do not support the involvement of platelet-activating factor in the vasodilatation of pregnancy, but indicate profound changes in cellular phospholipid metabolism in normal pregnancy with further disturbances in pregnancy-induced hypertension by as yet unexplained mechanisms.
