RESUMO

OBJECTIVE: Endothelial dysfunction is a major feature of preeclampsia. sVE-cadherin plays a role in the preservation and regulation of the endothelial barrier. For that reason, to evaluation of sVE-cadherin may help elucidate the disease pathophysiology of preeclampsia. METHODS: The sample size was calculated as a minimum of 46 pregnant women for each group based on serum sVE-Cadherin levels in a pilot study of 10 preeclamptic and 10 control groups. Hundred-twenty pregnancies complicated with early-onset (n = 60) and late-onset (n = 60) preeclampsia were compared with 120 gestational-age (GA)-matched (±1 week) uncomplicated pregnancies. The venous blood sampling was performed upon preeclampsia diagnosis prior to the onset of the labor in the preeclampsia group and the matching (±1 week) pregnancy week in the control group. Demographic and biochemical parameters were evaluated. RESULTS: Mean serum sVE-Cadherin was significantly higher in women with EOPE compared to that of the GA-matched control group (5.86 ± 1.57 ng/mL vs. 2.28 ± 0.80 ng/mL, p < 0.001), in women with LOPE compared to that of the GA-matched control group (3.11 ± 0.97 ng/mL vs. 1.69 ± 0.87 ng/mL, p < 0.001), and in women with EOPE compared to that of LOPE group (5.86 ± 1.57 ng/mL vs. 3.11 ± 0.97 ng/mL, p < 0.001) after correction for GA. Serum sVE-Cadherin positively correlated with systolic and diastolic blood pressure and a negative correlation with gestational age at sampling. CONCLUSION: The serum level of sVE-Cadherin was higher in women with preeclampsia than that of GA-matched healthy pregnant women, in women with EOPE compared to that of LOPE. sVE-Cadherin is an important marker in early-onset pre-eclampsia with severe clinical findings.

RESUMO

Objective: The study aims to determine whether the Pfannenstiel skin incision can be adjusted according to the fetal head's occipitofrontal diameter (OFD) during primary cesarean delivery. Background: Eligible 114 nulliparous women delivered at term by cesarean section in which Pfannenstiel skin incision was performed according to the OFD of the fetal head between June 2017 and September 2021 were included. Excluded cases were non-vertex presentations, all emergency cesarean sections, severe preeclampsia, women in an active phase of the first stage of labor and second stage of labor, placenta previa and low-lying placenta, multiple pregnancies, and uncontrolled gestational diabetes mellitus. Results: Among 114 eligible nulliparous women, the mean OFD was 116.1 ± 7.2 (99-138) mm, and the measurement of the Pfannenstiel skin incision length, which was performed according to the OFD was found to be 122.8 ± 9.2 (100-155) mm. The difference between OFD and Pfannenstiel incision kept remained within 10 mm in 90 (82.5.2%), 10-20 mm in 17 (15.5%), and more than 20 mm in two women (1.8%). This technique was successful in 109 (95.6%) out of 114 women without extending the skin incision. In five women, skin incision needed to be extended up to 38 mm. In 10 women (8.7%), the rectus abdominis muscle was cut partially to deliver the fetal head. The mean fetal umbilical artery pH was 7.33 ± 0.05. No neonatal hypoxia was encountered in the study. Conclusion: Pfannenstiel skin incision can be adjusted according to the OFD with minimal margins of error. This technique may provide better cosmetic results by avoiding unnecessarily prolonged incisions with similar newborn outcomes. Clinical Trial Registration: Clinicaltrials.gov, identifier [NCT05632796].

RESUMO

OBJECTIVE: To evaluate the serum vasostatin-1 levels in preeclamptic and non-preeclamptic pregnant women. MATERIALS AND METHODS: Thirty consecutive women with mild preeclampsia and sixty consecutive women with severe preeclampsia were compared with ninety gestational age-matched (±1 week) non-preeclamptic pregnant women with an appropriate-for-gestational-age (AGA) fetus. RESULTS: Mean serum vasostatin-1 was significantly higher in women with preeclampsia than gestational age-matched controls. Mean serum vasostatin-1 was significantly higher in the mild preeclampsia group compared to its gestational age-matched control group, and in the severe preeclampsia group compared to its gestational age-matched control group. There was no significant difference in mean serum vasostatin-1 levels between the mild and severe preeclampsia groups, and in severe early- and severe late-onset preeclampsia groups. Serum vasostatin-1 had positive correlations with systolic and diastolic blood pressure. CONCLUSION: Serum vasostatin-1 was significantly higher in women with preeclampsia compared to those of the gestational age-matched controls. There was no significant difference in mean serum vasostatin-1 levels between the mild and severe preeclampsia groups and severe early- and severe late-onset preeclampsia groups.

RESUMO

PURPOSE: This study aims to investigate the effect of using exogenous androgen on retinal microvascular structures in transgender men. METHODS: Retinal microvascular structures of transgender men and healthy women in the control group were visualized with optical coherence tomography angiography (OCTA). Foveal avascular zone (FAZ), superficial capillary vascular density (sCVD), deep capillary vascular density (dCVD), and radial peripapillary capillary (RPC) vascular density were evaluated. RESULTS: Thirty transgender men and 30 healthy women were included in the study. There were no significant differences between transgender men and the control group in terms of FAZ, central macular thickness, parafoveal, and perifoveal retinal thicknesses (p = 0.859, 0.288, 0.561, and 0.719; respectively). sCVD were found to be low in transgender men in the whole image, parafoveal, and perifoveal zones (p = 0.006, 0.025, and 0.005; respectively). Although there were low values of dCVD of the whole image, parafoveal, and perifoveal zones in transgender men, the difference was not statistically significant (p = 0.295, 0.085, and 0.270; respectively). RPC vessel densities in the whole image, peripapillary zone, and the inferior of the optic disc were found to be significantly low in transgender men (p = 0.003, 0.005, and 0.003; respectively). CONCLUSION: In this study, a decrease in vessel density in the superficial retinal layers and around the optic disc was detected in transgender men. These findings suggest that routine ophthalmological examination may be important in individuals who use exogenous androgens.

RESUMO

Catestatin can inhibit catecholamine release from chromaffin cells and adrenergic neurons. Catestatin can also have a strong vasodilator effect. This may be useful in understanding the pathophysiology of preeclampsia and its treatment. In this study, we investigated the serum catestatin levels in pregnant women with and without preeclampsia. Fifty consecutive women with mild preeclampsia, 50 consecutive women with severe preeclampsia, and 100 consecutive pregnant women with a gestational age-matched (±1 week) uncomplicated pregnancy were evaluated in a cross-sectional study. Mean serum catestatin was significantly increased in the preeclampsia group compared to the control group (290.7 ± 95.5 pg/mL vs. 182.8 ± 72.0 pg/mL). Mean serum catestatin was comparable in mild and severe preeclampsia groups (282.7 ± 97.9 pg/mL vs. 298.7 ± 93.4 pg/mL, p = .431). Serum catestatin levels had positive correlations with systolic and diastolic blood pressure, urea, uric acid, and creatinine. In conclusion, serum catestatin levels are increased in preeclamptic pregnancies compared to gestational age-matched controls.IMPACT STATEMENTWhat is already known on this subject? The role of autonomic nervous system dysregulation in the pathophysiology of preeclampsia is known. The most obvious part of this dysregulation is the sympathetic nervous system activation. The adrenal medulla is one of the locations of the sympathetic nervous system in the body.What do the results of this study add? Serum catestatin levels were found to be correlated with clinical and laboratory data of preeclampsia. This highlights the importance of chromaffin cell secretions in the adrenal medulla in preeclampsia.What are the implications of these findings for clinical practice and/or further research? This study will help understand the role of the adrenal medulla in the autonomic nervous system dysregulation in preeclampsia. Also, control of serum catestatin levels may support the treatment of hypertension in preeclampsia.

RESUMO

INTRODUCTION: Many people grieve in a resilient manner, often having a sense of equilibrium restored within six months. The most devastating type of loss is usually considered to be the death of the child. For such a loss, bereavement may take a period of distressing years with signs and symptoms that are related to grief. There have been different phases identified in the grieving process, and this process encompasses various difficulties with different levels of psychological effects. Women with perinatal losses can suffer long periods of grief. The purpose of this study was to monitor the grief in women who had undergone a termination of pregnancy due to fetal anomaly. METHODS: Forty-six women who applied to the Gynaecology Clinic of Istanbul University Cerrahpasa Faculty of Medicine and who decided to terminate their pregnancy due to fetal anomaly were included in the study. The Perinatal Grief Scale (PGS), the Impact of Event Scale-Revised (IES-R), Beck Anxiety Inventory (BAI), the Edinburgh Postnatal Depression Scale (EPDS), the Multidimensional Relationship Questionnaire (MRQ) and the Adult Attachment Scale (AAS) were administered to the participants six weeks after termination. Participants' grief signs were re-evaluated with the PGS at the sixth and 12th months. RESULTS: There was no relationship between severity of grief symptoms and socio-demographic and clinical characteristics of the patients. The perinatal grief symptoms can decrease gradually from termination of pregnancy to six months and can persist for a period of six months up to a year. There was positive correlation between the scores of PGS and BAI, IES-R hyper-arousal. The mean score of PGS changed significantly from sixth week to sixth month and from sixth week to 12th months. IES-R hyper-arousal and MRQ relational satisfaction were found to be the predictors for PGS total score at the first year. CONCLUSION: The diagnosis of fetal anomaly and especially the termination of pregnancy itself may be traumatic and disruptive. In women with perinatal loss, grief may become persistent after the first six months. It would be helpful to examine how the women resolve this experience. Especially the anxiety and the hyper-arousal signs following the termination should not be ignored. Perinatal grief is a unique bereavement experience; specific interventions should be performed for detecting and treating severe perinatal grief.

RESUMO

OBJECTIVE: To evaluate the possible associations between serum Neprilysin (NEP) levels and preeclampsia and mild and severe preeclampsia subgroups. MATERIALS AND METHODS: Fifty-five consecutive women with mild preeclampsia and fifty-five consecutive women with severe preeclampsia were compared with 110 approximately gestational age-matched (±1 week) women with an uncomplicated pregnancy. RESULTS: Mean serum NEP was significantly higher in women with preeclampsia compared to that of the gestational age-matched-controls (231.62 ± 65.30 pg/mL vs. 187.75 ± 84.38 pg/mL, p < 0.001). Mean serum NEP was significantly higher in the mild preeclampsia group compared to its gestational age-matched control group (228.84 ± 67.26 pg/mL vs. 186.14 ± 85.09 pg/mL, p = 0.008); and in the severe preeclampsia group compared to its gestational age-matched control group (234.45 ± 63.85 pg/mL vs. 189.29 ± 84.59 pg/mL, p = 0.004). Serum NEP was positively correlated with systolic and diastolic blood pressure, BUN, uric acid, and creatinine. CONCLUSION: Mean serum NEP was significantly higher in women with preeclampsia than women with an uncomplicated pregnancy. Further studies are needed to elucidate the possible therapeutic role of NEP inhibitors to treat preeclampsia.

RESUMO

Objective: To evaluate the serum survivin level in preeclampsia.Methods: Eighty-eight pregnancies complicated with preeclampsia and 88 gestational-age (GA)-matched uncomplicated pregnancies were evaluated.Results: Mean serum survivin was detected to be significantly decreased in the early- (EOPE) and late-onset (LOPE) preeclampsia subgroups than the GA-matched control-groups; and were comparable in EOPE- and LOPE-groups after correction for GA. Serum survivin had weak negative correlations with systolic and diastolic arterial blood pressure.Conclusion: The serum survivin level was decreased in preeclamptic patients than the GA-matched controls. More comprehensive studies are needed to clarify the timing and extent of placental apoptosis in preeclampsia.

RESUMO

Purpose: To investigate retinal vascular changes in pregnant women using optical coherence tomography angiography (OCTA).Materials and Methods: This prospective, cross-sectional study included 97 pregnant women and age-matched 34 healthy control subjects. The OCTA parameters of one eye (left) of pregnancy group and control group were compared. Besides, the OCTA parameters of three trimesters were compared between themselves and the control group. The foveal avascular zone (FAZ) area and the vessel density percentages of the superficial capillary plexus (SCP), deep capillary plexus (DCP), and radial peripapillary capillary (RPC) of all the groups were evaluated by OCTA.Results: In the pregnancy group, the vessel density of DCP was higher in all regions than the control group except the foveal region, but this difference could not reach statistical significance. On the other hand, the vessel density of SCP in the pregnancy group did not show a manifest change in all regions except the foveal region as in DCP. Although the FAZ area was wider in pregnancy group, this difference was not statistically significant (p:0.661). There was no statistically significant difference observed in vessel density of SCP, DCP, and RPC between the different trimesters and the control group, and none of these data correlated with the gestational week.Conclusion: This study showed retinal vascular changes secondary to pregnancy, especially in the vessel density of DCP. These results can provide information that should be taken into account in the evaluation and investigation of pregnancy-specific retinal vascular pathologies.

RESUMO

AIM: To evaluate the possible associations between creatine kinase (CK), cardiac troponin T (cTnT), N-terminal-pro-B-type natriuretic peptide (NT-proBNP), and s100B levels in umbilical cord blood and nonstress test results, cord-blood gas analyses and Apgar scores. MATERIAL AND METHODS: A total of 93 cesarean section deliveries after 34 + 0/7 gestational week (GW) were evaluated. The study (n = 50) and control (n = 43) groups consisted of type III and type I nonstress test (NST) according to the 2008 National Institute of Child Health and Human Development workshop report on electronic fetal monitoring. The serum levels of ProBNP II, S100-B, CK-MB, and cTnT were measured in cord blood and were evaluated according to the NST results, cord-blood gas analyses (pH and base-excess values) and 1- and 5-minute Apgar scores. Exclusion criteria for both groups included congenital abnormalities, multiple pregnancy, chorioamnionitis, oligohydramnios, polyhydramnios, intrauterine growth retardation (IUGR), and placental abruption. RESULTS: Mean age, weight, height, gestational age, and birth weight were comparable in type I and III NST groups. 1- and 5- minute Apgar, umbilical artery and vein pH values, and base deficiency were significantly lower in type III NST group compared to the type I NST group. The serum 100B (1616 ± 119 versus 533 ± 95 ng/L, p < .001), CK-MB (28.67 ± 21.17 versus 14.20 ± 11.26 ng/L, p < .001), cTnT (657 ± 396 versus 230 ± 132 ng/L, p < .001) and proBNP (1727 ± 379 versus 1069 ± 721 ng/L, p < .001) levels were significantly elevated in the NST type III compared to the NST type I group. The serum 100B, CK-MB, cTnT and proBNP levels were significantly elevated in the cord pH < 7.00 (n = 10) compared to pH = 7.00-7.15 group (n = 18). The serum 100B and proBNP were significantly elevated in the cord pH = 7.00-7.15 compared to the pH > 7.15 group (n = 65), whereas serum cTnT and proBNP levels were comparable in the latter two groups. In the study group, S100B, cTnT, and proBNP had negative correlations with 1- and 5-minute Apgar scores. All of the four markers showed negative correlations with A. umbilicalis pH and base excess. CONCLUSIONS: Mean S100B, CK-MB, cTnT, and NT-proBNP were significantly higher in the study group compared to the control group. The serum 100B, CK-MB, cTnT, and proBNP levels were significantly elevated in the cord pH < 7.00 compared to pH = 7.00-7.15 group. The serum 100B and proBNP were significantly elevated in the cord pH = 7.00-7.15 compared to the pH > 7.15 group.

RESUMO

Considering the complex pathogenesis of endometriosis, which is associated with many cellular or molecular processes, such as proliferation, angiogenesis, inflammation, we evaluated the diagnostic value of a quadruple panel of serum markers CA125, endocan, YKL-40 and copeptin, for the prediction of endometriosis and moderate - severe endometriosis. Seventy women with endometriosis and 70 women without endometriosis were evaluated. Serum CA125, endocan, copeptin and YKL-40 levels were significantly increased in women with endometriosis compared to the women without endometriosis and in the minimal - mild endometriosis group compared to the no-endometriosis group. YKL-40, endocan and copeptin levels were significantly increased in the moderate - severe endometriosis group compared to the mild -moderate endometriosis group but the difference in CA125 levels remained non-significant. The quadruple panel score had an AUC of 0.954, a sensitivity of 96.5% and specificity of 84.6% for prediction of moderate - severe endometriosis. Zero or one positive marker had a sensitivity of 91.4% and specificity of 88.57% to rule out endometriosis. In conclusion, a quadruple panel of serum markers-CA125, endocan, YKL-40, and copeptin may be beneficial for the diagnosis of endometriosis and especially moderate - severe endometriosis. Further studies are needed to prove the efficacy of this panel.Impact statementWhat is already known on this subject? Many serum markers including CA125 have been investigated so far and suggested to be associated with endometriosis. However, none of these markers is sensitive and specific enough to diagnose endometriosis.What do the results of this study add? A quadruple panel score (CA125, endocan, YKL-4 and copeptin) had an AUC of 0.954, a sensitivity of 96.5% and specificity of 84.6% for prediction of moderate - severe endometriosis.What are the implications of these findings for clinical practice and/or further research? A high score may be beneficial to warn the surgeon about the risk of moderate to severe endometriosis if the patient will be operated anyway. A negative test of the quadruple panel may show high odds that there is no endometriosis which may prevent unnecessary surgery.

RESUMO

OBJECTIVE: The study tested whether cardiovascular corresponding LPA risk genotypes improve pre-eclampsia and coronary heart disease (CHD) risk prediction beyond conventional risk factors. BACKGROUND: Studies have shown that women specific risk factors for cardiovascular disease (CVD) have taken an attention recently. It might be possible to identify women who have the highest risk in developing CVD in their further lives. It is well-known that Lp(a) levels have an impact on increased risk of CVD which is affected by LPA gene. Further, LPA risk genotypes are not considered in cardiovascular risk prediction. METHODS: We have included 200 pregnant Turkish women into the study. We stratified the preeclamptic (PE) group: early (EOP) (28.7 ± 3.0 weeks) and late onset (LOP) (36.0 ± 1.4 weeks). 14 LPA SNPs were evaluated in the study. Rs9355296 and rs3798220 were found as independent risk factors for preeclampsia by logistic regression analysis. A positive correlation was found between rs9355296 and the diagnostic criteria of preeclampsia. Further rs9355296 G/* carriers have higher vascular inflammation rather than AA carriers. CONCLUSIONS: The findings reveal that LPA genetic variability with high inflammatory response might be an indication of future cardiovascular events.

RESUMO

OBJECTIVES: To evaluate the serum levels of the serine proteinase inhibitor kallistatin in women with preeclampsia (PE). METHODS: The clinical and laboratory parameters of 55 consecutive women with early-onset PE (EOPE) and 55 consecutive women with late-onset PE (LOPE) were compared with 110 consecutive gestational age (GA)-matched (±1 week) pregnant women with an uncomplicated pregnancy and an appropriate for gestational age fetus. RESULTS: Mean serum kallistatin was significantly lower in women with PE compared to the GA-matched-controls (27.74±8.29 ng/mL vs. 37.86±20.64 ng/mL, p<0.001); in women with EOPE compared to that of women in the control group GA-matched for EOPE (24.85±6.65 ng/mL vs. 33.37±17.46 ng/mL, p=0.002); and in women with LOPE compared to that of women in the control group GA-matched for LOPE (30.87±8.81 ng/mL vs. 42.25±22.67 ng/mL, p=0.002). Mean serum kallistatin was significantly lower in women with EOPE compared to LOPE (24.85±6.65 ng/mL vs. 30.87±8.81 ng/mL, p<0.001). Serum kallistatin had negative correlations with systolic and diastolic blood pressure, creatinine, and positive correlation with GA at sampling and GA at birth. CONCLUSIONS: Serum kallistatin levels are decreased in preeclamptic pregnancies compared to the GA-matched-controls. This decrease was also significant in women with EOPE compared to LOPE. Serum kallistatin had negative correlation with systolic and diastolic blood pressure, creatinine and positive correlation with GA at sampling and GA at birth.

RESUMO

Aim: The expressions of caveolin-1 have only been examined in the placental tissue of patients with preeclampsia and were reported to be low. Therefore, we decided to investigate the maternal serum levels of caveolin-1 in patients with preeclampsia.Material and methods: This cross-sectional study was conducted including 87 pregnant women; 32 with normal pregnancy and 55 with preeclampsia. Maternal serum levels of caveolin-1 were measured by using enzyme-linked immunosorbent assay kit (ELISA).Results: The mean serum caveolin-1 level was significantly lower in women with preeclampsia (PE) compared with the control group (11.48 ± 0.92 versus 12.94 ± 1.36 ng/ml) and being lowest in the early onset PE group (11.24 ± 0.74 ng/ml). Serum caveolin-1 concentrations did not correlate with maternal age and BMI. However, caveolin-1 concentrations were negatively correlated with systolic blood pressure (r = -0.467, p = .001) and diastolic blood pressure (r = -0.441, p = .001) as well as with umbilical artery resistance index (r = -0.275, p = .01).Conclusion: Maternal serum caveolin-1 levels are significantly lower in patients with PE than controls. The serum caveolin-1 levels inversely correlate with blood pressure and umbilical artery Doppler parameters.

RESUMO

The aim of this study was to investigate the role of PON1Q192R and L55M single nucleotide polymorphisms(SNPs) and its association with the maternal levels of lipid parameters in gestational diabetes mellitus(GDM) and preeclampsia(PE). Ninety-nine pregnant with GDM, 97 pregnant with PE and 98 healthy pregnant were included in the study. No statistically significant difference was observed in the alleles or in the genotypes frequencies of SNPs between groups. In GDM patients, total cholesterol was higher in MM genotype of L55M gene (p < .05); Lp(a) were lower in LM genotype of the gene compared to their respective control (p < .05). In PE, HDL-C levels were higher in LM genotype (p < .05); LDL-C levels were lower in MM genotype of the gene compared to their respective control (p < .05). In PE patients, malondialdehyde(MDA) were higher in QQ genotype compared to their respective control (p < .05). Triglyceride levels were higher in PE patients with QR genotype compared with GDM patients with QR genotype (p < .05). Our results indicated that lipid profiles, Lp(a) and MDA levels showed significant differences in GDM and PE pregnants. These findings support the importance of the lipid profile, oxidized lipid and Lp(a) in different genotypes of L55M and Q192R in Turkish pregnant women with PE/GDM suggesting their roles in etiopathogenesis in these pregnancy-related disorders.

RESUMO

AIM: To establish how useful and the predictive capacity of uterocervical angles (UCA) in the termination of second trimester pregnancies. MATERIAL AND METHODS: This prospective cohort study was conducted at a tertiary center with a total of 120 singleton pregnancies delivered between 14 and 24 gestational weeks. Before the beginning of misoprostol induction, patients were screened for both cervical length (CL) and uterocervical angles (UCA). The UCA is defined as an angle constructed by the measurement of the cervical canal and lower uterine segment. The study population was subdivided into four groups; successful and failed terminations at the end of 24 hours of induction and successful and failed terminations at the end of 48 hours of induction. We decided to further evaluate our study population based on their UCAs, and placed them into four categories; UCA ≥95°, UCA <95°, UCA ≥105°, and UCA <105°. RESULTS: In the 24-hour time frame group, the mean UCA was 105.50 ± 15.38 degrees in the successful termination group and was 100.22 ± 11.12 degrees in the failed group (p = .001). In the 48-hour time frame group, the mean UCA was 104.19 ± 13.51° in the successful termination group and was 93.52 ± 7.84° in the failed group (p = .007). The mean hour of induction was shortest in the UCA ≥105° group. CONCLUSIONS: Regardless of the time frames, patients who had successful terminations had a broader angle, less amount of misoprostol use and shorter duration of induction as compared to the failed termination groups. What do the results of this study add? The uterocervical angle has never been measured in second trimester pregnancies to predict the timing of termination. Our study demonstrated the useful application of this ultrasonographic finding in the prediction of successful second trimester terminations.

RESUMO

OBJECTIVES: Intercellular adhesion molecule-1 (ICAM-1) plays an important role in endothelial function. Hyperglycemia-induced impaired redox status is 1 of the well-known pathophysiologic characteristics of gestational diabetes mellitus (GDM), and it plays a crucial role in the causes of disease. Our aim was to clarify any possible relationship between the ICAM-1 Lys469Glu polymorphism and systemic redox status in women with and without GDM. Also, we investigated whether this polymorphism could be associated with a change for better or worse as evidenced by clinical and redox biomarkers. METHODS: The ICAM-1 polymorphism statuses of 89 pregnant women without GDM and 53 pregnant women with GDM were found. Stratifying patients based on GDM and polymorphism status, we investigated various redox homeostasis markers. The independent t test was used. RESULTS: Significantly higher systemic oxidative damage and diminished antioxidant defense were found in pregnant women with GDM. Also, results showed that whether pregnant women were carrying the Lys469Glu polymorphism or not did not seem to be associated with significant differences, as evidenced by comparable systemic oxidative damage. CONCLUSIONS: Although no significant difference was observed between genotypes, the oxidative damage observed in patients with GDM warrants earlier screening and management in the light of new evidence.

RESUMO

AIM: The aim of this study is to investigate the maternal levels of collectrin in early-onset preeclampsia (EOPE) and late-onset preeclampsia (LOPE). To assess the correlation between serum collectrin levels and blood pressure in humans. MATERIAL AND METHODS: This cross-sectional study was conducted including 79 pregnant women, 27 with normal pregnancy, 30 with EOPE and 22 with LOPE. Maternal serum levels of collectrin were measured by using enzyme-linked immunosorbent assay kits. RESULTS: The mean serum collectrin level was significantly lower in women with PE compared with the control group (8.49 ± 3.12 ng/ml (EOPE), 9.69 ± 3.01 ng/ml (LOPE) versus 11.51 ± 4.33 ng/ml) and was found to be the lowest in the EOPE group (8.49 ± 3.12 ng/ml). The mean serum urea and uric acid levels were significantly higher in the PE group than the control group. Serum collectrin concentrations did not correlate with maternal age, BMI and serum creatinine levels. However, collectrin concentrations were negatively correlated with systolic blood pressure (r = -0.284, p = .011) and diastolic blood pressure (r = -0.275, p = .014) as well as with maternal serum urea (r = -0.269, p = .017) and uric acid (r = -0.219, p = .049) concentrations. CONCLUSION: Maternal serum collectrin levels are significantly lower in patients with preeclampsia than in the control group. There is an inverse correlation between serum collectrin levels and blood pressure.

RESUMO

PURPOSE: Lipoprotein lipase-associated phospholipase A2 (Lp-PLA2) is a vascular inflammatory marker associated with cardiovascular diseases (CVD). Women with preeclampsia (PE) have elevated vascular inflammation and at higher CVD risk in the later life. We hypothesize that vascular inflammation related genetic variations increase the risk for developing future cardiovascular disease in women with PE. To test this hypothesis, we studied PLA2G7 gene polymorphisms, Lp-PLA2 mass, activity, index, and other cardiovascular risk factors in women with preeclampsia. METHODS: A total of 200 pregnant women were included into the study. We stratified the PE group: early (28.7 ± 3.0 weeks) and late onset (36.0 ± 1.4 weeks). Serum Lp-PLA2 mass in the early PE and the late PE group were significantly higher than the control group (p = .000). Lp-PLA2 index, Hs-C-reactive protein (CRP), serum amyloid A (SAA), calprotectin, and PTX3 levels were higher in early and late PE (p = .000). Single-nucleotide mutations of PLA2G7 rs1805017 (r = -0.228, p < .05) and rs9381475 (r = 0.216, p < .05) were correlated with LpPLA2 mass for the early PE group. Logistic regression analysis showed that LP-PA2 mass an independent risk factor for early PE with rs1805017 and rs9381475 carriers. CONCLUSIONS: Lp-PLA2 genetic variability with vascular inflammatory markers might contribute the incidence of future cardiovascular events.
