Preeklampsinin Patogenezinde Maternal Oksidatif Stres, Demir/Çinko, Bakır/Çinko Oranları ve Eser Element Düzeylerinin Rolü

Purpose:Preeclampsia (PE) is a complex disease and the underlying mechanisms are not known, yet. It is well known that oxidative stress and trace elements play a role in the pathogenesis of various diseases. Several studies have shown that the levels and proportions of trace elements are closely related to the severity of the disease. The aim of the study was to investigate the changes in some characteristics parameters, serum zinc, iron, copper levels, and copper/zinc and iron/zinc ratios and plasma lipid peroxidation levels in patients with mild and severe preeclampsiaAmaç: Preeklampsi (PE) kompleks bir hastalıktır ve hastalığın patogenezinde yer alan mekanizmalar henüz aydınlatılamamıştır. Oksidatif stres ve eser elementlerin çeşitli hastalıkların patogenezinde rol oynadığı iyi bilinmektedir. Yapılan çeşitli çalışmalarda, eser elementlerin düzeylerinin ve oranlarının, hastalığın şiddeti ile yakından ilişkili olduğunu göstermiştir. Bu çalışmanın amacı, hafif ve şiddetli preeklamptik hastalarda bazı karakteristik özelliklerin, serum çinko, demir, bakır düzeyleri, bakır/çinko ve demir/çinko oranları ile plazma lipid peroksidasyon düzeylerini değişikliklerini araştırmaktı

Relationships Among Some Biochemical Parameters, Trace Elements and Lipid Peroxidation Levels in Women With Gestational Diabetes Mellitus

Aim:The aim of the present study was to determine levels of copper (Cu), zinc (Zn), iron (Fe), malondialdehyde and some biochemical parameters in women with gestational diabetes mellitus (GDM) compared with healthy pregnant women, and to evaluate the relationships among these parameters.Materials and Methods:The patients consisted of 56 pregnant with GDM. The control group consisted of 60 healthy pregnant women. Plasma malondialdehyde, blood glucose, insulin, glycosylated hemoglobin (HbA1c), total cholesterol, triacylglycerol and LDL-cholesterol were measured by biochemical methods. The concentrations of serum Fe, Cu and Zn were determined by flame atomic absorption spectrophotometer.Results:The levels of blood glucose, insulin, HOMA-IR, glycosylated hemoglobin (HbA1c), total cholesterol, triacylglycerol and LDL-cholesterol, levels of plasma malondialdehyde, levels of serum Fe and Cu in women with GDM group were found higher than those in healthy pregnant women. However, levels of serum Zn were significantly lower in GDM pregnants than those in the healthy pregnant women. There were significant negative correlations between LDL-cholesterol and Cu levels of GDM subjects. Additionally, there were significant negative correlation between LDL-cholesterol and plasma malondialdehyde levels. However, there were significant positive correlations between serum Fe and plasma malondialdehyde levels.Conclusion:Our findings emphasize the significant deficiencies of Zn levels and the significant elevation of malondialdehyde, hyperglycemia and hyperlipidemia in women with GDM. Therefore, supplementation with Zn element involved in the antioxidative system may increase antioxidative enzyme activities, and consequently, an improvement in fetal and maternal complications may be expected

Non-invasive diagnosis of endometriosis and moderate-severe endometriosis with serum CA125, endocan, YKL-40, and copeptin quadruple panel

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 statement What 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

Identifying prognostic factors which affect the success of ectopic pregnancy treatment with a single dose methotrexate

Objective: To identify prognostic factors which affect the success of ectopic pregnancy treatment with a single dose metotrexate. Methods: 99 patients whom applied to Cerrahpaşa Medical Faculty Obstetrics and Gynecology Department, between year 2000 and 2010 treated with single-dose methotrexate were divided into two subgroups; successful and unsuccessful. Likely to affect the success of the demographic clinical and laboratory findings were compared retrospectively. Results: Single-dose MTX therapy has been successful in 67 patients (% 67.6). In the unsuccessful group, serum ß- hCG values were significantly higher than successful group. (Successful group ß -hCG value: 1180±953 mIU/ml, Unsuccessful group ß- hCG value: 5613±7630 mIU/ml,p: 0,001) Conclusion: Single-dose MTX therapy is effective in the initial treatment of ectopic pregnancy. It is observed that the main prognostic factor affecting the success is elevated levels of ß -hCG

Role of spiramycin in prevention of fetal toxoplasmosis

WOS: 000374773800006PubMed ID: 26365472Objective: The aim of this study is to evaluate the efficacy of spiramycin in prevention of mother-to-child transmission of Toxoplasma gondii infection. Methods: Patients within first trimester of their pregnancy with Toxoplasma IgM positivity (>0.65 index, ELISA, VIDAS) and IgG positivity (>8 IU/ml), who had low IgG avidity (<0.50 index, ELISA, Architet) were considered as having acute toxoplasmosis. These patients who had amniocentesis at the 19th-21st week of pregnancy were examined for the detection of Toxoplasma DNA. Detailed ultrasonographic examinations performed between the 20th and 24th gestational weeks and the mothers and babies were followed for at least one year. Results: Out of 61 patients, 55 (90.2%) had received Spy prophylaxis while 6 (9.8%) cases refused Spy prophylaxis. Toxoplasma PCR test was found to be positive in amniotic fluid of 4 (6.6%) patients obtained by amniocentesis at the 19th-21st week of pregnancy. All four of these patients had refused Spy prophylaxis had positive Toxoplasma PCR in amniotic fluid (p<0.01). Conclusion: Our results seem to encourage the use of spiramycin in women with toxoplasmosis during pregnancy
