Fundus changes in pregnancy induced hypertension

AIM: To determine the prevalence of retinal changes in pregnancy induced hypertension (PIH) and any association between the retinal changes and blood pressure, proteinuria, and severity of the disease. METHODS: All the patients admitted with diagnosis of PIH were included in this study. Age, race, gravida, gestation period, blood pressure, and proteinuria were noted from the case records. After taking history for any eye symptoms, fundus examination was done after dilating the pupils with direct ophthalmoscope in the ward itself. All the findings were noted on a data sheet, and were analyzed using SPSS programme. RESULTS: A total of 78 patients of PIH were examined. Majority (75.6%) were Malays. The mean age of patients was 30.2 years (range 21-45 years). The gestation period ranged from 25 weeks to 41 weeks; 34 (43.5%) were primi gravida. Thirty (38.4%) patients had mild preeclampsia, 46 (59%) had severe preeclampsia and 2(2.5%) had eclampsia. Retinal changes (hypertensive retinopathy) were noted in 46 (59%) patients --- grade I in 41 (52.6%) and grade II in 5 (6.4%). Haemorrhages or exudates or retinal detachment were not seen in any patient. There was statistically significant positive association of retinal changes and blood pressure (P =0.001), proteinuria (P =0.018) and severity of the PIH (P =0.024). CONCLUSION: Retinal changes (grade I and II hypertensive retinopathy) were seen in 59% of patients with PIH and they were significantly associated with blood pressure, proteinuria and severity of the disease. Fundus examination helps in assessing the severity of PIH.

Expression of Endothelial Nitric Oxide Synthase Traffic Inducer in the Placenta of Pregnancy Induced Hypertension

The expression of endothelial nitric oxide synthase traffic inducer （NOSTRIN） in the placenta of the patients with pregnancy induced hypertension （PIH） was detected and its role in the pathogenesis of PIH was studied. The pathological changes in placental vessels were observed by HE staining. NO2-/NO3- , the stable metabolic end products of NO, was measured with nitrate reductase. The eNOS activity in placental tissues was assayed by spectrophotometry. Western blot analysis was applied to detect NOSTRIN expression. The incidence of thickening and fibronoid necrosis of placental vessels was significantly higher in women with PIH than in the normal group （P〈 0.01）. The levels of placental NO2-/NO3- in PIH patients （27. 53±7.48 μmol/mg） were significantly lower than in normal group （54. 27±9.53 μmol/mg, P〈0.01）. The activity of eNOS was significantly decreased in PIH group （12. 826±3.61 U/mg） as compared with that in normal group （21. 72±3.83 U/mg, P〈0.01）. Western blot analysis revealed that both groups expressed 58 kD NOSTRIN, but the protein level was significantly higher in women with PIH than in the normal group （P〈0.01）. A significant negative correlation existed between the expression of NOSTRIN protein and the activity of eNOS in placental tissue of women with PIH （r=-0.57, P〈0.01）. It was concluded that the level of NOSTRIN expression in placenta of women with PIH was increased, which may play an important role in the pathogenesis of PIH.

Immunohistochemical Analysis of Globulin and Complements in Blood Vessels of Placental Villi during Pregnancy Induced Hypertension

The changes of globulin and complements in placental villi blood vessels were immunohistochemically studied in pregnancy induced hypertension patients and normal pregnant patients by a randomized , double-blind approach. The immunostaining of IgG, IgE, C3, C4, and 5-HT was seen in the villous blood vessels and the helicine arteries of pregnancy induced hypertensive placental villi.The strong positive rates were 100%, 90%, 100%, 100% and 90% in seriouspregnancy induced hypertensive patients, accompanied by aggregation of mastocytes and vasculopathy of villous blood vessels and the helicine arteries. It is concluded that the immuno-pathological damage took place in the villous blood vessels and helicine arteries, resulting in vasculopathy and villous regressive changesand that the immunological factors were closely related to pregnancy induced hypertension.

A Cross-Sectional Study on Current Practice of the Management of Pregnancy Induced Hypertension and Its Maternal and Foetal Complications and Outcome in the Western Part of the State of Libya

Background: Maternal and perinatal mortality and morbidity are mainly affected by hypertension during pregnancy (pre-eclampsia). Haemorrhage and cerebral bleeding are the primary and significant complications of pre-eclampsia. Abruption of the placenta and renal failure are among the major complications caused by this disease. The perinatal complications include Intrauterine Growth Restriction (IUGR), Intrauterine Foetal Death (IUFD), neonatal death, and prematurity. Objective: The purpose of the present study was to examine the incidence of Pregnancy-Induced Hypertension (PIH), pre-eclampsia, the management of PIH, including the early diagnosis, the pharmacological drug management used, and the prevalence of maternal and perinatal complications. Methods and Patients: This cross-sectional study took place in Aljalaa maternity hospital, which represented the west of the state of Libya in the period from 1st January 2012 to 31st December 2012, with patients who were diagnosed, managed, and terminated according to protocol management of the hospital. Results: In the present study, from the total deliveries in Aljalaa Maternity hospital, the incidence of PIH is 8.4% and pre-eclampsia is 5.1%. No maternal mortality, CNS haemorrhaged, hepatic failure, or renal failure. The reported maternal complications included: Eclampsia, HELLP syndrome (Haemolysis, Elevated Liver enzymes and Low platelets), abruption placenta, and pulmonary oedema see in eighteen percent, six percent, nine percent, four percent and less than one percent, respectively. The foetal complications were preterm babies and Intrauterine Growth Restriction (IUGR) in nineteen percent, Low Birth Weight (LBW) in twenty-five percent, Intrauterine Foetal Death (IUFD) in five percent, neonatal death in two percent and, perinatal death in six percent. In the PIH patients, the presence of associated symptoms such as headache, blurred vision, irritability, and the presence of signs such as severe hypertension, generalized oedema, exaggerated reflexes, and abnormal investigations (protein urea, high uric acid, abnormal LFT, haemoconcentration, and low pits) increased the risk of maternal and foetal complications. Conclusion: To decrease mother and newborn mortality and morbidity in PIH patients, a rigorous management protocol is required to implement evidence-based guidelines.

INVESTIGATION OF THROMBOMODULIN AND PLASMINOGEN ACTIVATOR INHIBITOR TYPE-I IN PREGNANCY INDUCED HYPERTENSION AND ITS CLINICAL SIGNIFICANCE

Objective. To measure the circulating levels of thrombomodulin (TM) and plasminogen activator inhibitor type- I (PAI- I) in women with pregnancy induced hypertension (PIH). Methods. Blood samples were drawn from 97 pregnant women in their third trimester, grouped as 25 mild PIH,26 moderate PIH,22 severe PIH and 24 normotensive healthy pregnant women for determining levels of TM by ELISA,PAI- I by colorimetric assay methods, and creatinine (Cr) in serum by biochemical method. Results. Circulating levels of TM, PAI- I and TM/Cr ratio increased with increasing severity of PIH. There were no significant differences between mild and normotensive pregnant women. The parameters were significantly changed in the moderate and severe PIH groups. Conclusion. TM and PAI- I may serve as meaningful clinical markers for the assessment of the endothelial damage in PIH, which is very important in evaluating and following the development of PIH.

Effect of Prepared Rhubarb on Insulin Resistance in Patients With Pregnancy Induced Hypertension

Objective: To investigate the effect of prepared rhubarb on insulin resistance in patients with pregnancy induced hypertension (PIH) and its mechanism. Methods: All the 92 patients accepted 75 g oral glucose tolerance test (OGTT) and insulin release test before and after treatment. These patients were divided into two groups (treated group and control group). Prepared rhubarb and nifedipine were given to the treated group, while nifedipine was given to the control group alone. Circulating endothelial cell (CEC), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) were measured and glucose area under curve (GAUC), insulin area under curve (IAUC), insulin sensitivity index (ISI) were calculated. And 30 normal pregnant women were selected as the healthy group. Results: CEC, TNF-a, IL-6, GAUC and IAUC of PIH patients were significantly higher than those of the normal healthy group; while ISI of PIH patients was significantly lower than that of the healthy group. ISI was significantly negatively correlated to CEC, TNF-a and IL-6. After treatment, CEC, TNF-α, IL-6, GAUC decreased and ISI increased significantly in the treated group; while in the control group, all above-mentioned parameters showed no change. Conclusion: Prepared rhubarb can improve insulin resistance of PIH by reducing vascular endothelial cell's damage.

Association of Urinary Strontium Levels with Pregnancy-induced Hypertension

Pregnancy-induced hypertension(PIH),including gestational hypertension and preeclampsia,accounts for the majority of maternal and perinatal morbidity and mortality.Strontium(Sr)has been recently associated with preeclampsia in a small group of women;however,the role of Sr in PIH is not fully understood and warrants further investigation.In this study,we examined the association between urinary Sr levels and PIH,and assessed the effect of maternal age on the association.Urinary Sr concentrations were measured in 5423 pregnant women before delivery by inductively coupled plasma mass spectrometry(ICP-MS).Logistic regression analysis adjusting for potential confounders was applied to explore the association between Sr and PIH,and to evaluate the Sr-PIH relationship stratified by maternal age.Among the participants,200(3.83%)women were diagnosed with PIH.Compared with non-PIH women,women who developed PIH had lower urinary Sr concentrations(131.26 us.174.98μg/L creatinine,P<0.01).With the natural log-transformed urinary creatinine-standardized Sr concentrations increasing,the risk of PIH decreased significantly[adjusted OR=0.60(95%CI:0.51,0.72)].Furthermore,the significant association of Sr with PIH was found among women under 35 years(P<0.01).Our finding suggested that Sr may play a potential protective role in the pathogenesis of PIH,especially among young pregnant women under 35 years old.

Establishment of a model for pregnancy-induced hypertension syndrome resulting from cold-stress in rats

Objective: To establish a model for pregnancy-induced hypertension syndrome in rats. Methods: Adult female Wistar rats were randomized into non-pregnant control (NN), non-pregnant cold-stress control (NC), pregnant control (PN) and pregnant cold-stress (PC) groups. The rats of NN and PN groups were put under 25 ℃ and those of NC and PC groups under (4±2)℃ for 4 h every morning respectively in the whole experimental period. The blood pressure, urine protein, body weight, haematocrit, weight of the placenta and weight and length of the fetus were recorded and the histological changes of the placenta and the kidneys were also studied. Results: The blood pressure and urine protein of the rats of the NC and PC groups after 2 weeks of cold-stress were more significantly increased than the rats of the NN and PN groups. In addition, the weight of the placenta and the weight and length of the fetus were more significantly lower in the former than the latter. Obvious changes of anoxia and ischemia were observed in the tissues of the kidneys and every layer of the placenta. Conclusion: Our findings of hypertension syndrome induced with repeated cold-stress in pregnant rats can be applied to illustrate the pathogenesis of pregnancy-induced hypertension syndrome in human beings.

Objective:To investigate the change of the hs-CRP,sVC AM-1,NT-proBNP levels of the patients with pregnancy-induced hypertension(PIH) syndrome.Methods:A total of 200 patients with PIH were divided into mild,moderate and severe group,and 50 healthy pregnancy patients served as the control group.The serum sVCAM-1 levels were detected by enzyme-linked immunosorbent assay,hs-CRP were detected by immunity transmission turbidity,and NT-proBNP levels were determined by the colloidal gold method.Patients were treated with magnesium sulfate and nifudipine and the contrastive analysis was performed before and after treatment.And the pathological changes in placental of PIH patients were delected by hematoxylin-eosin staining at the same time.Results:The hs-CRP,sVCAM-l,NT-proBNP levels of patients in the mild, moderate and severe PHI group were significantly higher than that in the control group(P<0.05). The hs-CKP,sVCAM-l,NT-proBNP levels in the severe group were significantly higher than the mild group and the moderate group,the difference was statistically significant(P<0.05).The hsCRP,sVCAM-l,NT-proBNP of the moderate group were significantly higher than the mild group(P<0.05).There was a positive correlation between hs-CRP,sVCAM-1,NT-proBNP expression levels and the degree of the PIH.The expression of hs-CRP,sVCAM-1,NT-proBNP levels of the moderate and the severe group were significantly decreased(P<0.05).The number of placental villi and interstitial blood vessel in the moderate and severe PIH group were significantly less than the control group(P<0.05).Conclusions:The increased levels of serum hs-CRP,sVCAM-1, NT-proBNP may be involved in the process of vascular endothelial cell injury of the PIH,and the hs-CRP,sVCAM-1,NT-proBNP can be used as the auxiliary index for diagnosis of PIH and determination of PIH severity.

Increased Oxidative Stress in Women With Pregnancy-induced Hypertension

Objective To investigate whether pregnancy-induced hypertension （PIH） may increase oxidative stress in women with PIH, and to explore the mechanisms by which PIH may increase oxidative stress and potential free radical damage. Methods Seventy women with PIH and seventy women with uncomplicated normotensive pregnancy （UNP） whose age, nutritional conditions, levels of hemoglobin and albumin were all matched, were enrolled in a randomized controlled trial. Their plasma concentrations of nitric oxide （NO）, vitamin C （VC）, vitamin E （VE）, and β-carotene （β-CAR） as well as their erythrocyte malondialdehyde （MDA）, and activities of superoxide dismutase （SOD）, catalase （CAT） and glutathione peroxidase （GPX） were determined by spcctrophotometry. Results Compared with average values of the above experimental parameters in the women with UNP, the average value of erythrocyte MDA in the women with PIH significantly increased （P〈0.0001）, while the average values of plasma NO, VC, VE, and β-CAR as well as those of erythrocyte SOD, CAT, and GPX in the women with PIH significantly decreased （P〈0.0005-0.0001）. The findings from partial correlation analysis （controlling for age） for 70 women with PIH showed that with elevated systolic blood pressure （SBP） and diastolic blood pressure （DBP）, MDA value gradually increased （P〈0.001）, and NO, VC, VE, β-CAR, SOD, CAT, and GPX values gradually decreased （P〈0.02-0.001）. The findings from reliability analysis for NO, VC, VE, β-CAR, SOD, CAT, GPX, and MDA values used to reflect increased oxidative stress and potential free radical damage in women with PIH showed that the reliability coefficients （alpha, 8 items） = 0.7062, P〈 0.0001, and the standardized item alpha = 0.9116, P〈 0.0001. Conclusion The findings in the present research suggest that pregnancy-induced hypertension can increase oxidative stress and potential free radical damage in women with pregnancy-induced hypertension.

The subtractive cDNA library of PIH placenta was set up and screedned. Differential cDNAs were cloned, and sequenced by T 7 primer methodology. One hundred and three differential cDNAs were isolated by SSH. Sequencing and BLAST analysis showed 90 inserts shared more than 95% homolog with sequences in the GenBank/EMBL database. We identified 36 putative genes including pregnancy-specific glycoprotein gene (BC005924), serine protease inhibitor gene(BC012868), VEGFR-1 gene(AF063657, etc.

The Expression of PLF in Placenta in Pregnancy-Induced Hypertension and the Relationship between the PLF and Serum VCAM-1

To study the expression of placental isoferritin (PLF) in placental tissue of pregnancy-induced hypertension (PIH) and the relationship between the level of expression of PLF and the amount of vascular cell adhesion molecule-1 (VCAM-1) in serum, immunohistochemical technique was used to detect the expression of PLF in placenta tissue in 45 PIH patients (PIH group) and 15 normal pregnant women (normal group). High resolution pathological image analysis system (HPIAS-100) was employed to determine the quantity of PLF. The VCAM-1 in serum was examined by enzyme linked immunoabsorbent assay (ELISA). The results showed that the levels of PLF expressions in moderate and severe PIH patients were significantly lower than that of normal group (P<0. 01). The serum VCAM-1 was significantly decreased in PIH group (1310±177 ρ/ng/ml) than that of normal group (609±72 ρ/ng/ml, P<0. 01). The significant negative correlation existed between the expression of PLF in placental tissue and the serum VACM-1 (r=-0. 58, P<0. 01). It was concluded that the level of PLF expression in PIH decreases and is negatively correlated with the amount of serum VCAM-1, indicating that these may be involved in the pathogenesis of PIH.

The Activity of Plasma Platelet-activating Factor Derived from Pregnant Women before and after Delivery and lts Relation to Pregnancy-induced Hypertension

The activity of plasma platelet-activating factor(PAF) from pregnant women before and after delivery was determined. Plasma samples were taken from 74 pregnant women, among whom 24 were normotensive controls, 30 mild and moderate hypertensive and 20 severe hypertensive. Of the two hypertensive groups(pregnancy-induced hypertension, PIH), PAF activity measured by a bioassay was significantly higher than that of normotensive control at 38 weeks in gestation , indicating a possible role of this potent lipid mediator in the pathophysiological mechanism of PIH. After delivery, PAF activity was obviously increased in all three groups , showing the regulation of placenta in PAF metabolism.
