Preeclampsia (PE) is characterized by a series of clinical features such as hypertension and proteinuria associated with endothelial dysfunction and the impairment of placenta vascular endothelial integrity. This study aimed to investigate the effect of serum copper (Cu) level on some angiogenesis-related factors including vascular endothelial growth factor-A (VEGF-A), soluble Fms-like tyrosine kinase-1 (sVEGF-R1), soluble endoglin (sEng) and cerruloplasmin (Cp) in Iraqi women with preeclampsia (PE) and control pregnant women. Therefore, 60 women with PE in addition to 30 healthy pregnant women were enrolled in the study. Serum concentration of sEng, VEGF-A, sVEGF-R1, and Cu in PE group significantly increased (p<0.05) in the PE group compared with that in the control group. Increased production of antiangiogenic factors, soluble VEGF-A and sEng contribute to the pathophysiology of PE, indicating the involvement of these parameters in the angiogenic balance in patients with PE. Tests for between-subject effects showed that the circulating angiogenesis factors and Cu were significantly associated with the presence of PE. Serum Cu level was significantly correlated with VEGF- A and VEGF-R1 levels but not with sEng. Multiple regression analysis revealed that only Cp and BP can significantly predict the complications in women with PE. In conclusion, serum Cu has a role in the angiogenesis in women with PE and may be a new drug target in the prevention or treatment of PE.

Abstract Preeclampsia (PE) is a syndrome related with pregnancy and characterized by hypertension and proteinuria, occurring in approximately 6-8% of pregnancies and accounting for approximately 40% of premature births. This study aimed to investigate the polymorphisms of -634C/G and +936C/T in VEGF gene and their relationship with serum VEGF levels in pregnant women with PE. In this case-control study, peripheral blood samples were collected from 135 women with PE and 135 normal pregnant women as the control group. DNA was extracted using the phenol-chloroform method. Then, the polymorphisms of VEGF gene were detected by PCR-RFLP method using specific primers. Besides, VEGF concentrations were measured by ELISA method on serum samples and control subjects using ELISA kits. In this research, maternal age, gestational week, maternal hemoglobin and BMI were significantly correlated with the likelihood of PE, while the occurrence season variable was not effective in PE among the pregnant women. There was no significant difference in the two polymorphisms of -634C/G and +936C/T in VEGF gene between the two groups. Also, the serum VEGF level in PE patients was significantly higher than the normal group (P<0.001). Despite a significant increase in serum VEGF concentrations in women with PE, it seems that -634C/G and +936C/T polymorphisms of VEGF gene are not related with the onset of PE. Further studies are required to fully understand the risk factors related to preeclampsia syndrome.

Background: Pre-eclampsia(PE) is  the  most  frequently encountered  medical  complication  during  pregnancy. In developing countries PE   is a principal cause of maternal mortality. A disturbance  in  the  angiogenic/antiangiogenic  factors  and  in  the  hypoxia/placental re-oxygenation  process,  seems  to  activate a maternal  endothelial  dysfunction.Aims and Objective: To estimate Vascular Endothelial Growth Factor ( VEGF )  level  in the cord blood of healthy and Preeclamptic ( PEc ) pregnant women and to associate this with Preeclamptic pregnancy.Material and Methods: A case-control study ofUmbilical cord serum VEGF levels from women with uncomplicated pregnancies (control group, n=60) and pregnancies complicated by Pre-eclampsia (n=40). VEGF in the cord serum was estimated by SANDWICH Enzyme Linked Immunosorbent Assay method by using ELISA Kit and then compared between the two groups.Results: The mean VEGF concentrations in the women who had pre-eclampsia  (578.62±468.3)  were lower than in the control group( 625.75±533.1) , but the difference was not statistically significant ( p= 0.8548).  Conclusion VEGF plays a key role in the instability between endothelial dysfunction and angiogenesis that occurs during Preeclampsia.  VEGF levels might be a useful tool for the early diagnosis of Pre-eclampsia.Asian Journal of Medical Sciences Vol.8(1) 2017 21-25

Objective: To find out the effect of honey administration on changes in antiangiogenic and proangiogenic serum levels in the rat model of preeclampsia. This study is the first research that examines the effect of honey on preeclampsia especially on proangiogenic and antiangiogenic factors Methods: This study uses analytic research with a quasi-experimental design in laboratory rats (Rattus Norvegicus) pregnant females given honey with concentration. The treatment of all samples was carried out simultaneously and during the treatment it was observed using the type of postest only control group design. Results: Honey administration significantly reduced sFlt-1 levels in preeclampsia rats, and a greater dose of honey had an effect on strengthening the effect of honey in reducing sFlt-1 levels. Honey administration significantly increased VEGF levels in preeclampsia mice (p = 0.034). Honey administration significantly decreased s-Eng levels in preeclampsia mice, and administration of a larger dose of honey had an effect on strengthening the effect of honey in reducing s-Eng levels (p = 0.012). Conclusion: The honey administration on rat’s model of preeclampsia may reduce the antiangiogenic level sFlt-1 and sEng dan increase VEGF level as the pro-angiogenic

As circulating levels of vascular endothelial growth factor (VEGF-A) are raised in malignancy, the aim of this study was to investigate whether similar changes occur in two related factors, VEGF-D and the soluble VEGF-A receptor Flt-1 (sFlt-1). Circulating levels of VEGF-A, VEGF-D and sFlt-1 were determined by ELISA in 51 patients with primary breast cancer and matched healthy controls. Results were correlated with clinicopathological data. Whilst there was a difference in VEGF-A levels between patient and control groups (p=0.03), no such difference was observed for sFlt-1 or VEGF-D levels and there was no association between individual factors and the clinicopathological variables examined. However, there was a positive correlation between VEGF-A and sFlt-1 levels in both patient and control groups (p<0.0001). In addition, the ratio of sFlt-1 to VEGF-A was significantly different between patients and controls (p<0.0001) and was also associated with tumour size (p=0.01) within the patient group. During tumour progression there is a change in the relative amounts of sFlt-1 and VEGF-A in the circulation. Measuring the sFlt-1:VEGF-A ratio may have more significance than VEGF-A alone and further studies are needed to determine whether the ratio is of use as a prognostic marker or as a means of monitoring response to anti-angiogenic therapy in cancer.

Platelets initiate hemostasis by aggregating at the site of injury and participate in ensuring endothelial integrity. A defect in this process could lead to intravascular blood loss. This case-control study sought to determine the platelet counts and indices among pregnant women in the University of Abuja Teaching Hospital Gwagwalada, Abuja, Nigeria. A total of 120 pregnant women as case and 60 non-pregnant women as control were enrolled for this study. Blood samples were collected in EDTA tubes, and complete platelet count and indices were carried out using an automated five-part haematology analyzer. The mean ± standard deviation of the platelets count among the pregnant women, 226.54 ± 69.76 109 cells/L was not significantly different from that of the non-pregnant women, 214.95 ± 52.22x 109 cells/L (p=0.295). There was a significant differences in mean platelets volume (MPV) of the case and control groups (p=0.036). After post-hoc test, the significant difference was between the  pregnant women in 3rd trimester and the control group (p=0.014). However, there was no diffences in the mena platelets larger cell ratio and platelet distribution width in the case and control groups. Fifteen (11.0%) and 7 (12.1%) of the case and control control groups, respectively had mild thrombocytopenia. However, there was no significant association between pregnant status and thrombocytopenia (p=0.836). Based on these findngs, it can be infered that platelet count and MPV decreases while PDW increase with the progression of gestation age compared to the non-pregnant women.

ABSTRACT Objective: To evaluate the frequency of polymorphisms in the vascular endothelial growth factor (VEGF) gene, as well as to identify a potential risk haplotype among the polymorphic regions in this gene in patients with disc degeneration and in the Control Group. Methods: This study analyzed a total of 217 individuals distributed into the Disc Degeneration and Control Groups. Peripheral blood was collected from all patients to detect VEGF gene polymorphisms identified by qPCR (rs699947, rs1570360, rs2010963, rs833061 and rs3025039). All patients presenting disc degeneration had the confirmation by nuclear magnetic resonance test and were rated according to disc degeneration level. Results: All polymorphisms were in Hardy- Weinberg equilibrium (p>0.05) in the studied population. The genotypic frequency for Disc Degeneration and Control Group were rs699947 p = 0.475, rs1570360 p = 0.862, rs2010963 p = 0.823, rs833061 p=0.596 and rs3025039 p=0.230. In haplotype analysis, the compositions CAGGC (p=0.094) and CCGGC (p=0.054) stood out. Conclusion: The correlation between VEGF gene polymorphism as a risk predictor for disc degeneration was negative in the studied population. However, the VEGF gene has a large polymorphic region, and it is activated by various catabolic and metabolic factors in the disc degeneration process, which has not been fully elucidated.

The article presents the predictors of placental dysfunction on the early stage of pregnancy. The objective: the search for prognostic markers and criteria for the occurrence of placental insufficiency in the early stages of the gestational process to optimize the pregnancy and labor with improved perinatal outcomes. Patients and methods. To solve this goal in the period from 2013 to 2015 were conducted a comprehensive survey of 334 pregnant women, which depending on the peculiarities of pregnancy and childbirth were divided into groups. The control group consisted of 236 pregnant women with uncomplicated gestational period, no morphological signs of placental dysfunction. The study group included 98 patients with a complicated pregnancy who had revealed violations of the fetal-placental relations, which was confirmed by morphological examination of the placenta in the postpartum period. Results. It was found that pregnant women with placental insufficiency in the first trimester of pregnancy have higher levels of interleukin-1B (IL-1v) and interleukin-3 (IL-3) in comparison with physiological pregnancy, as well as there is a direct significant correlation between IL-1v and pulsative index (PI) in the spiral (r=0.84) and uterine artery (r=0.77), and the inverse correlation between the level of IL-3 and PI in the terminal branches of the umbilical artery (r=-0.69). Verified an inverse relationship between the concentration of endothelin-1, the level of vascular endothelial growth factor (r=-0.87) and placental growth factor (r=-0.73), and also a direct link between the content of endothelin-1 and PI in spiral arteries (r=0.89), uterine artery (r=0.83) and the terminal branches of the umbilical artery (r=0.79). Conclusion. Thus, it is proven that early predictors of placental dysfunction can be considered the concentration of endothelin-1, vascular endothelial growth factor, placental growth factor, interleukin-1, interleukin-3, and the indices of pulsative index. Key words: placental dysfunction, predictors, endothelin-1, vascular endothelial growth factor, placental growth factor, interleukin, pulsative index.
