Objective.?To investigate the alterations of maternal antepartum and postpartum plasma levels of sE-selectin and VE-cadherin in normotensive pregnant women, women with preeclampsia (PE), gestational hypertension (GH), and gestational proteinuria (GP).

Methods.?A total of 37 pregnant women were included in the present study; 12 with PE, 10 with GH, 5 with GP, and 10 controls. sE-selectin and VE-cadherin levels were assessed in maternal plasma at three periods; before delivery, 3–6 days after delivery, and 12–14 weeks postpartum.

Results.?Women with severe preeclampsia (SPE) and GP had significantly higher plasma sE-selectin levels as compared to controls in all three periods of sampling. In the GH group, sE-selectin levels did not differ from controls. During the study, even after 12 weeks postpartum, the plasma sE-selectin levels remained unchanged in all preeclamptic groups (PE, GH, and GP). There was no difference in VE-cadherin levels between women with preeclampsia (PE, GH, and GP) and normal pregnancies.

Conclusions.?We found no changes in VE-cadherin levels in preeclamptic groups. Increased antepartum and postpartum levels of sE-selectin in women with SPE and GP suggest that endothelial dysfunction may be one of the key processes in the pathogenesis of PE and the underlying mechanism, as well, that links PE with cardiovascular disease in later life. GP, also, appears to be a mild variant of PE.  相似文献

Objectives.?To evaluate the association between endothelial activation markers in the maternal circulation with nitric oxide (NO) synthesis in human umbilical endothelial cells.

Study design.?This is a case-control study of normal and pre-eclamptic pregnancies. The levels of sE-selectin, soluble vascular cell adhesion molecule 1 (sVCAM-1), and soluble fms-like tyrosine kinase 1 (sFlt-1) were measured by enzyme-linked immunosorbent assay, and histamine-induced NO synthesis was detected by fluorometric examination of the human umbilical vein endothelial cells (HUVECs) isolated from normal and pathological pregnancies.

Results.?Mothers with severe pre-eclamptic pregnancies have premature and smaller babies than mothers with normal pregnancies (P?<?0.05); they also have high maternal plasma levels of sVCAM-1 (~2-fold), sFlt-1 (~2.5-fold), and lower (~70%) histamine-stimulated NO synthesis in HUVECs. A positive relationship between systolic blood pressure (SBP) and plasma levels of sE-selectin, sVCAM-1, and sFlt-1 was demonstrated. Moreover, levels of sE-selectin, sVCAM-1, and sFlt-1 were negatively associated with newborn weight (NBW), gestational age at delivery, and NO synthesis. Women with high E-selectin (>63?ng/ml), VCAM-1 (>752?ng/ml), and sFlt-1 (>15204 pg/ml) showed high risk (~2-fold) for preterm delivery and very preterm delivery, or fetal weight <1500?g (~1.5-fold) compared with women with low levels.

Conclusions.?High circulating levels of maternal endothelial dysfunction markers present in pre-eclampsia are associated with decreased NO synthesis in fetal endothelium.  相似文献

BACKGROUND: The combination of genetic susceptibility and environmental factors induce allergic sensitization and subsequently local inflammation, resulting in atopic manifestations. OBJECTIVE: To examine whether immunological features reflecting sensitization (total and specific IgE levels, allergen-induced proliferative responses and skin tests) and markers of inflammation (plasma sE-selectin and blood eosinophils) are related to the clinical expression of atopy and whether they precede atopic disease in children up to 2 years of age. METHODS: The development of these markers during the first 2 years of life was studied prospectively in 133 newborns at high risk to develop atopic disease. RESULTS: The prevalence of atopic disease increased from 25% at 12 months to 32% at 24 months of age. The children with food allergy at 12 months, who all had atopic dermatitis (AD), turned out to have asthma-like disease in 40% and AD in 100% at the age of 24 months. Total IgE levels increased with time and from 12 months onward levels started to differ markedly between atopics and nonatopics. Food-specific IgE antibodies were significantly associated with AD (relative risk [RR] = 2.39), food (RR = 1.32) and upper-airway allergy (RR = 1.20), and house dust mite-specific IgE antibodies with upper-airway allergy (RR = 5.00). A positive skin test was significantly associated with AD (RR = 2.90) and food allergy (RR = 1.36). The inflammation markers investigated, were not related to the clinical expression or preceded atopic disease at 2 years of age in high-risk children. CONCLUSION: Positive skin tests and specific IgE to food or inhalant allergens were related to the clinical expression of different atopic diseases. The combination of AD and food allergy at 12 months reflected the strongest risk factor in this high risk cohort for the development of asthma-like disease at 24 months of age.  相似文献

BACKGROUND: Better diagnosis of metastatic disease has been pursued by oncologists: however, many of the tumor markers have been still controversial. Our purpose was to estimate the usefulness of soluble E-selectin and its ligand sialyl Lewis A for more accurate diagnosis as a combined tumor marker for metastases in colorectal cancer. METHODS: E-selectin and sialyl Lewis A, collected from preoperative blood, were measured of its levels in 54 patients with colorectal cancer classified according to Dukes' stage. E-selectin was assayed by enzyme-linked immunosorbent assay, whereas sialyl Lewis A was quantified by enzyme immunoassay using immunoclone kit. RESULTS: The elevation in the level of E-selectin was significantly higher in Dukes' D group than that of healthy volunteers (P < 0.001, Fisher's procedure of least significance test), Dukes' A (P = 0.01), B (P = 0.025) and C (P < 0.01). Significantly higher level of sialyl Lewis A was shown in the group of metastases than that of non-metastases (P < 0.0068. Student's t-test). Paired elevation of E-selectin and sialyl Lewis A was significantly higher in the hematogenous metastases than non-metastases (P < 0.001, Fisher exact test). CONCLUSIONS: These results suggest that E-selectin could play some role in the progress of hematogenous metastases. The elevation of E-selectin alone or both E-selectin and sialyl Lewis A may be one of the useful indexes for more precise diagnosis of hematogenous metastases of human colorectal cancer.  相似文献

目的:探讨急性脑梗死患者外周血sE-选择素、sL-选择素表达水平的变化、临床意义.方法:对30例急性脑梗死患者采用酶联免疫吸附技术(EUsA)定量测定发病<72 h、7天时外周血血清sE-选择素、sL-选择素的表达水平,并与20例健康者作对照.结果:发病<72 h、7天时外周血sE-选择素的表达水平分别为(10.49±8.70)ng/ml、(5.74±4.40)ng/ml,均显著高于对照组(均P<0.01);且与发病<72 h相比,发病7天时下降明显,其差异有显著性(P<0.01).发病<72 h、7天时外周血sL-选择素的表达水平分别为(4.29±2.22)ng/ml、(4.27±2.11)ng/ml,均显著低于对照组(均P<0.01);7天与<72 h相比其表达水平差异无显著性(P0.05).结论:急性脑梗死时患者外周血sE-选择素表达上调而sL-选择素表达下调;它们可能参与了急性脑梗死的病理过程,对临床治疗有参考价值.  相似文献
