Öğe Assessment of arterial stiffness with an easy method in preeclamptic patients(Oxford Univ Press, 2014) Oylumlu, M.; Oylumlu, M.; Yuksel, M.; Yildiz, A.; Bilik, M. Z.; Akil, M. A.; Ozler, A.[Abstract Not Available]Öğe Association between mean platelet volume and different phases of menstrual cycle in primary dysmenorrhea(Imr Press, 2013) Soydinc, H. E.; Evsen, M. S.; Sak, M. E.; Ozler, A.; Turgut, A.; Gul, T.Purpose: Blood cells play a major role in homeostasis and inflammation. Primary dysmenorrhea (PD) involves the production of prostaglandins and leukotrienes, which cause inflammation in uterine tissue. Aim of this study was to investigate whether there is a relation between complete blood count parameters and PD during the menstrual cycle. Materials and Methods: The study included 41 cases diagnosed as primary dysmenorrhea (mean age, 23.02 +/- 3.43 years) and 40 individuals who control subject (mean age, 23.76 +/- 3.13 years). Hematologic parameters were measured on menstrual phase (day 1-4), follicular phase (day 9-12), and luteal phase (day 21-23) during menstrual cycle. Results: There were no statistically differences between hematological parameters of two groups except for mean platelet volume (MPV). MPV of PD and control groups at each phase of menstrual cycle were 7.71 vs 8.61 (p = 0.01); 7.66 vs 8.56 (p = 0.005); 7.75 vs 8.53 (p = 0.01), respectively. Conclusion: PD is associated with decreased MPV and platelets may be involved in the inflammatory process of PD.Öğe Copper, ceruloplasmin and oxidative stress in patients with advanced-stage endometriosis(Verduci Publisher, 2013) Turgut, A.; Ozler, A.; Goruk, N. Y.; Tunc, S. Y.; Evliyaoglu, O.; Gul, T.AIM: To compare patients with advanced stage endometriosis with control patients without endometriosis with respect to serum Copper (Cu) and Ceruloplasmin (Cp) levels and oxidative stress markers in order to evaluate the importance of these parameters in the pathogenesis of endometriosis. PATIENTS AND METHODS: A total of 72 women who underwent laparoscopy or laparotomy for evaluation of infertility, pelvic pain, pelvic mass, tubal ligation or endometriosis were enrolled for this prospective clinical study. Patients were divided into two groups by visual diagnosis at surgery and histological confirmation of endometriosis: control patients (n=41) without endometriosis and study group (n=31) with stage III/IV (advanced stage) endometriosis. Serum Cu, Cp, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), paraoxonase-1 (PON-1), malondialdehyde (MDA), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) levels were compared between the two groups. Correlations between Cu, Cp and oxidative stress markers were determined. RESULTS: Serum TOS, OSI, Cu, Cp, TG, TC, LDL were significantly higher, whereas TAS, PON-1 activity and HDL were significantly lower, in women with advanced-stage endometriosis than in control groups. There was no difference in serum MDA activities between the two groups. Positive correlations were found between Cu and TOS, Cu and OSI, Cu and Cp, while a negative correlation was found between Cu and PON-1 in the advanced-stage endometriosis group. Positive correlations were found between Cp and TOS, and Cp and OSI in the advanced-stage endometriosis group. CONCLUSIONS: Cu and Cp appear to be associated with the etiopathogenesis of and oxidative stress in endometriosis.Öğe Effects of estrogen, estrogen/progesteron combination and genistein treatments on oxidant/antioxidant status in the brain of ovariectomized rats(Verduci Publisher, 2013) Evsen, M. S.; Ozler, A.; Gocmez, C.; Varol, S.; Tunc, S. Y.; Akil, E.; Uzar, E.INTRODUCTION: The aim of this study was to investigate the antioxidative effects of estradiol (E), E plus progesteron (P) combination (E/P) and genistein (G) treatment in the brain of ovariectomized (OVX) rats. MATERIALS AND METHODS: Adult female Sprague-Dawley rats were divided into five groups, with each group including ten rats. Rats were anesthetized and bilateral ovariectomy was performed under general anaesthesia in all groups except for the sham operation group. Groups included: Sham-operated, control (OVX), estrogen treated group (OVX+ E), E/P combination group (OVX+ E/P) and G treated group (OVX+ G). Treatments were applied for 8 weeks. The total anti-oxidant status (TAS), total oxidant status (TOS), nitric oxide level (NO), glutathione peroxidase activity (GSH-Px) and oxidative stress index (OSI) were analysed in the brain tissue of rats from each treatment category. RESULTS: Ovariectomy lead to an increase in brain TOS and OSI levels compared to the sham group (p < 0.05). Also, ovariectomy resulted in a decrease in brain TAS levels compared to the sham group that approached statistical significance (p = 0.078). Significant decreases in TOS, OSI, GSH-Px and a significant increases in TAS and NO levels were observed in the E-treatment group compared to the control group (p < 0.001). The E/P combination group exhibited a significantly decreased TOS and OSI and significantly increased TAS and NO levels relative to the control group (p < 0.05). Genistein treatment resulted in a significant decrease in TOS and OSI compared to the control group (p < 0.05). CONCLUSIONS: Oxidative stress markers increase in the brain tissue of OVX rats. Conversely, estradiol, E/P and G supplementation decreases oxidative stress markers and increases antioxidant activity. Using G may prevent neural pathologies result in menopause-related oxidative stress.Öğe Evaluation of the relationship between preeclampsia and seropositivity of infectious disease in maternal plasma(Soc Editrice Univ, 2013) Soydinc, H. E.; Kan, I.; Dal, T.; Evsen, M. S.; Sak, M. E.; Ozler, A.; Turgut, A.Purpose. The aim of the present study was to investigate the association between maternal infections and preeclampsia. Materials and Methods. Fifty-four pregnant women with preeclampsia (study group) and 54 healthy pregnant women (control group) were enrolled in this study. Chlamydia pneumoniae (CP), Mycoplasma hominis (MH), Helicobacter pylori (HP), Cytomegalovirus (CMV), Herpes simplex virus type 2 (HSV-2), and Toxoplasma gondii (TG) antibodies were analyzed in the maternal plasma of all of the participants. Results. There was no difference in the demographic data between groups. Maternal plasma seropositivity for CP IgM; MH IgA and IgG; HP IgM, IgA and IgG; TG, CMV and HSV-2 IgM and IgG were not significantly different between the preeclampsia and control groups. The seropositivity for CP IgG was significantly higher in women with preeclampsia versus the control women. Conclusions. Our results suggested that preeclampsia is associated with CP IgG seropositivity.Öğe Fibroblast growth factor-1 expression in the endometrium of patients with repeated implantation failure after in vitro fertilization(Verduci Publisher, 2013) Sak, M. E.; Gul, T.; Evsen, M. S.; Soydinc, H. E.; Sak, S.; Ozler, A.; Alabalik, U.BACKGROUND: An examination of the alterations in Fibroblast Growth Factor-1 (FGF-1) expression in a group of repeated implantation failure after in vitro fertilization (IVF) patients, when compared to fertile patients. PATIENTS AND METHODS: Study group consisted of 24 patients with repeated implantation failure and 29 fertile control patients. Endometrial samples received at the luteal phase were exposed to immunohistochemical staining for the fibroblast growth factor-1 (FGF-1) with antibodies. RESULTS: In the study group all patients have primary infertility (n = 24), and the average duration of infertility was 3.9 +/- 1.3 years. The average recurrent IVF failure was 2.6 +/- 0.6 attemps. There were no significant differences in the histological data according to the Noyes classification (p = 0.226) and age (p = 0.231) between the patients in the study and control groups (n=29). The control group was found to have more severe expression of FGF-1 (< 0.001) than the study group when endometrial glandular epithelial cells, stromal cells and vascular endothelial cells were evaluated. CONCLUSIONS: Endometrial glandular epithelial cells, stromal cells and vascular endothelial cells of the control and study group were evaluated and it was found that the control group displayed a stronger expression of the FGF-1 (< 0.001). The expression of FGF-1 in the IVF implantation failure group is less than in the fertile group, which suggests that growth factors such as FGF-1 are important maternal factors effecting implantation.Öğe Increased platelet count in severe peritoneal endometriosis(I R O G Canada, Inc, 2014) Evsen, M. S.; Soydinc, H. E.; Sak, M. E.; Ozler, A.; Turgut, A.; Celik, Y.; Tunc, S. Y.Objective: Platelet count (PC) is higher in chronic inflammatory diseases. The aim of this study was to evaluate the PC in patients with severe pelvic endometriosis. Materials and Methods: Patients with advanced stage pelvic endometriosis were retrospectively evaluated in a tertiary center between January 2009 and December 2011. Patients with pelvic endometriosis were divided into two groups; advanced stage peritoneal endometriosis were classified as Group 1 (n = 28). Group 2 consisted of 29 patients which had ovarian endometrioma without clinically apparent peritoneal endometriosis foci. Group 3 included 51 women as control subjects. PC between the groups was tested by Student's t test. The mean values of three groups were analyzed by using one way ANOVA test followed post-hoc test Bonferroni. Results: PC in patients with pelvic endometriosis were found to be higher from the control group (290 +/- 67 10(9)/1; 264 63 +/- 109/1, respectively; p = 0.038). Patients with peritoneal endometriosis (Group 1) had significantly higher PCs compared with the healthy controls (309 +/- 65 109/1; 264 +/- 63 10(9)/1; respectively; p = 0.011). Conclusion: Increased PC in advanced stage pelvic endometriosis may be a sign of increased systemic inflammation. The systemic inflammation may be more apparent in advanced stage peritoneal endometriosis.Öğe New inflammatory markers in preeclampsia: echocardiographic epicardial fat thickness and neutrophil to lymphocyte ratio(Oxford Univ Press, 2014) Oylumlu, M.; Ozler, A.; Yildiz, A.; Oylumlu, M.; Acet, H.; Polat, N.; Soydinc, H. E.[Abstract Not Available]Öğe Risk factors for maternal mortality in eclampsia: analysis of 167 eclamptic cases(Verduci Publisher, 2012) Sak, M. E.; Evsen, M. S.; Soydinc, H. E.; Turgut, A.; Ozler, A.; Sak, S.; Celik, Y.BACKGROUND: The aim of this study was to evaluate risk factors associated with maternal mortality in patients with eclampsia. METHODS: The probable risk factors of maternal mortality including maternal age, length of hospital stay, gestational age, systolic and diastolic blood pressures; hematocrit, hemoglobin, platelet count, levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase were determined from patients' charts and Odds ratios (OR) of these factors were detected using by logistic regression analysis. RESULTS: According to logistic regression model, AST [OR, (95% Confidence Interval, CI): 7.39 (2.71-20.13)]; ALT [6.45 (2.42-17.16)]; postpartum diastolic blood pressure [4.58 (1.80-11.62)]; hematocrit [3.52 (1.86-6.65)]; hemoglobin [2.67 (2.01-3.55)] were found to be significant risk factors for maternal mortality. CONCLUSIONS: In eclamptic patients, close monitoring of particular laboratory values and blood pressure, and early intervention to alterations of certain variables will provide possibility for prevention against potential complications and subsequently decreasing mortality.Öğe Serum levels of neopterin, tumor necrosis factor-alpha and Interleukin-6 in preeclampsia: relationship with disease severity(Verduci Publisher, 2012) Ozler, A.; Turgut, A.; Sak, M. E.; Evsen, M. S.; Soydinc, H. E.; Evliyaoglu, O.; Gul, T.AIM: There are many studies evaluating the role of inflammation in the pathogenesis of preeclampsia. However, little is known about the relationship between the severity of inflammation and the severity of preeclampsia due to insufficient of studies reporting this matter. To investigate the maternal serum concentrations of IL-6, TNF-alpha and Neopterin in patients with mild preeclampsia and severe preeclampsia and HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome in preeclampsia and determine their association with the severity of the disease. PATIENTS AND METHODS: Patients, hospitalized with the diagnosis of preeclampsia between October 2011 and March 2012, were included in the study. The patients with preeclampsia were divided into three groups as mild preeclampsia, severe preeclampsia and HELLP syndrome. The control group was comprised of normotensive and uncomplicated pregnant women. The serum levels of IL-6, TNF-alpha and Neopterin (NEO) were determined, using enzyme-linked immunosorbent assay. Spearman's rank correlation tests were used for the correlations between the serum levels of inflammatory markers and the severity of preeclampsia. RESULTS: There was no observed significant difference among mean serum TNF-alpha and IL-6 levels of four groups (p > 0.05). The median serum concentration of NEO in subjects with mild preeclampsia of 14.1 nmol/L and severe preeclampsia of 14.8 nmol/L was significantly higher than that of 10.3 nmol/L in normotensive controls (p = 0.013; p = 0.000 respectively). In addition, the median serum concentration of NEO was detected to be highest in subjects with HELLP syndrome. The serum levels of NEO was well correlated with the severity of preeclampsia (r = 0.533, p = 0.000). CONCLUSIONS: The serum levels of NEO, an important marker of cellular immunity, associated with severity of disease in patients with preeclampsia.Öğe Serum levels of the adipokines, free fatty acids, and oxidative stress markers in obese and non-obese preeclamptic patients(I R O G Canada, Inc, 2015) Turgut, A.; Ozler, A.; Goruk, N. Y.; Tunc, S. Y.; Sak, M. E.; Evsen, M. S.; Evliyaoglu, O.Purpose of investigation: To investigate the roles of adipokines, free fatty acid (FFA), and oxidative stress in obese and non-obese preeclamptic patients. Materials and Methods: Gestational age-matched obese preeclamptic (n=32), non-obese preeclamptic (n=32),and non-obese normotensive healthy (n=32) pregnant women were included in the study. Serum insulin, insulin resistance, leptin, nesfatin, ghrelin, chemerin, FFA levels, total antioxidant status, total oxidant status, and oxidative stress index were determined. Results: Leptin and nesfatin levels were significantly lower and ghrelin levels were significantly higher in the normotensive group as compared to the preeclamptic groups, while no difference was observed between obese and non-obese preeclamptic groups. Chemerin and FFA levels were significantly higher in obese preeclamptics as compared to non-obese preeclamptics and normotensive group. Total antioxidant status (TAS) levels were significantly higher in the normotensive group as compared to the preeclamptic groups, while no difference was observed between obese and non-obese preeclamptics. Total oxidative status (TOS) and oxidative stress index (OSI) levels were significantly lower in the normotensive group as compared to the preeclamptic groups, while no difference was observed between obese and non-obese preeclamptics. Conclusion: Serum levels of adipokines, TOS, and FFAs were significantly higher in pregnants with preeclampsia as compared to non-obese normotensive controls. Chemerin and FFA levels were significantly higher in obese preeclamptics as compared to non-obese preeclamptics.
