ABSTRACT

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.

ABSTRACT

In this study, we evaluated the value of the uterocervical angle (UCA), myometrial thickness (MT), sICAM-1, sVCAM-1, soluble E-selectin (sE-selectin) and pentraxin 3 (PTX3) levels in women with threatened preterm labour (TPL) in predicting spontaneous preterm birth (sPTB) within 14 days in symptomatic women with cervical length (CL) measurements between 10 and 25 mm. Forty-six patients diagnosed with TPL, 47 healthy pregnant women were evaluated in a case-control study. sE-selectin (AUC = 0.744, p = .007) and PTX3 (AUC = 0.711, p = .019) were found to be effective in predicting preterm delivery within 14 days. In conclusion, maternal sE-selectin and PTX3 levels may be helpful in identifying pregnancies that will deliver within 14 days in symptomatic women with CL measurements between 10 and 25 mm. However, maternal sICAM-1 and sVCAM-1 levels, MT and UCA are not effective in the prediction of sPTB in TPL pregnancies. Impact StatementWhat is already known on this subject? Aetiology of spontaneous preterm birth (sPTB) is unclear and believed to be multifactorial, infection, inflammation, vascular endothelial dysfunction and uteroplacental ischaemia are all considered to be related to preterm delivery syndrome. Transvaginal cervical length (CL) measurement is a good indicator of increased risk of sPTB. Inflammation is accepted to have a central role in the process of labour.What do the results of this study add? soluble E-selectin (sE-selectin) and pentraxin 3 (PTX3) levels may be helpful in identifying pregnancies that will deliver within 14 days in symptomatic women with CL measurements between 10 and 25 mm.What are the implications of these findings for clinical practice and/or further research? This study will help understand the important role of the inflammatory process in predicting spontaneous preterm birth.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

INTRODUCTION: The ultimate treatment approach for cervical ectopic pregnancy remains controversial. Gestational age, serum ß-hCG levels, fetal cardiac activity presence and the patient's claim for fertility preservation are the major challenges for method of choice in each individual case. Medical treatment may be a favorable option for the treatment of late diagnosed cases, as well as the early ones. PRESENTATION OF CASE: In this case report, we aim to present a case of 10 4/7 weeks of cervical ectopic pregnancy successfully treated with transvaginal ultrasound-guided local and systemic methotrexate injection. DISCUSSION: The case presented here is exceptional because even though the advanced gestational age, presence of fetal cardiac activity and high serum ß-hCG values, the abortion has occurred successfully. Conservative treatment without any need of further surgical intervention was sufficient for full recovery with the preservation of reproductive capacity. CONCLUSION: In conclusion, transvaginal ultrasound guided local and systemic methotrexate injection may be performed successfully for the cases of advanced gestational age with fetal cardiac activity and high serum ß-hCG levels.

ABSTRACT

AIM: The purpose of this study was to evaluate the impact of mode of delivery on the sexual function of women using the Female Sexual Function Index (FSFI). METHODS: This was a prospective study of 452 nulliparous women, comparing their sexual function before and after birth. A Turkish version of the FSFI questionnaire was administered within the first 8 weeks of pregnancy, at 3 and 6 months postpartum in a face-to-face manner and subsequently at the 12th month and 24th month over the telephone. RESULTS: Age, BMI, education level, house income, duration of marriage, birthweight, and feeding at each time point were similar between group 1 [vaginal birth and mediolateral episiotomy (MLE)] and group 2 [caesarean section (CS)]. In the postpartum period, there were 265 and 138 participants at 3rd month, 216 and 121 participants at 6th month, 189 and 111 participants at 12th month, and 133 and 85 participants at 24th month in group 1 and 2, respectively. The FSFI total scores decreased at 3 and 6 months postpartum in both groups (27.3 to 23.1 in group 1 and 27.5 to 25 in group 2; p < 0.05 for both). Desire, arousal, lubrication, satisfaction and pain scores were significantly decreased at 3 months postpartum in group (1) In group 1, desire, arousal and pain scores remained decreased at the 6th month compared to initial scores. Group 2 had significantly lower desire, lubrication, satisfaction and pain scores at 3 months postpartum compared to their initial scores. Decline in desire and lubrication domains persisted at the 6th month for group (2) None of the FSFI domain scores differed after 6th months when compared to pre-delivery scores in both groups. Compared with the caesarean group, the vaginal birth with MLE group had lower satisfaction and higher pain levels at 3 months postpartum (p < 0.0001, for both). None of the FSFI domains differed at the 6th, 12th or the 24th month between the groups. CONCLUSION: Our study revealed that caesarean section is not superior to vaginal birth in terms of preservation of normal sexual function, regardless of short-term postpartum effects. Women should be informed that, irrespective of their type of delivery, sexual function 6 months after childbirth is similar to that in pre-pregnancy.
