Maternal and umbilical serum levels of interleukin-6, interleukin-8, and tumor necrosis factor-α in normal pregnancies and in pregnancies complicated by preeclampsia

Objectives. The aim of this study was to investigate the relationship of maternal and umbilical cord interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α) serum levels with the existence and severity of preeclampsia. A particular objective was the comparison of normal umbilical serum levels to preeclamptic values. Materials and Methods. The study group consisted of 24 patients with third trimester singleton pregnancies complicated by preeclampsia (15 severe and 9 mild preeclampsia). The gestational age-matched 19 healthy pregnant women were compared by study group. Maternal and umbilical serum IL-6, IL-8, and TNF-α were calculated by using enzyme-linked immunosorbent assay. Results. Significantly increased maternal and umbilical serum levels of IL-6, IL-8, and TNF-α were found in preeclamptic patient group in comparison with the control group. Maternal serum IL-8 and TNF-α concentration were significantly higher in patients with severe preeclampsia than in mild preeclampsia. Increased umbilical serum levels of IL-6 and IL-8 were found in severe preeclampsia than in mild preeclampsia. There were significantly higher levels of maternal serum IL-8 and TNF-α in patients with preeclampsia with IUGR than in patients with preeclampsia with normal fetal growth. Conclusion. Our findings suggest that increased concentrations of IL-6, IL-8, and TNF-α in the maternal and umbilical serum play a significant role in pathogenesis of preeclampsia. Alterations in maternal and umbilical serum levels of IL-6, IL-8, and TNF-α may also play role in preeclampsia complicated by intrauterine growth retardation. These associations may offer insight into the etiology and pathogenesis of preeclampsia.

May ratio of neutrophil to lymphocyte be useful in predicting the risk of developing preeclampsia? A pilot study.

Abstract Objective: The aim of the study was to evaluate the relationship between neutrophil to lymphocyte ratio (NLR) and preeclampsia. Methods: Demographic data and laboratory tests for NLR of 203 pregnant women (73 normotensive pregnants, 23 pregnants with mild preeclampsia and 107 pregnants with severe preeclampsia) were retrospectively analyzed. Neutrophil to lymphocyte ratios were compared between the study groups. Results: Preeclamptic pregnant women had smaller gestation weeks, lower hemoglobin level and fetal birth weight than that of normal pregnant women. NLR in preeclamptic group was significantly higher than that of normal group (p = 0.023) and area under ROC curve was found statistically significant (p = 0.023). However, there was no statistically significant relationship between NLR and severity, proteinuria level, subjective symptoms and onset time of the disease. Conclusion: The findings showed that the measurement of NLR periodically may be useful to predict high-risk pregnancies in terms of preeclampsia, but further studies are needed to determine its contribution.

May the Platelet to Lymphocyte Ratio be a Prognostic Factor for Epithelial Ovarian Cancer

BACKGROUND The study aimed to evaluate changes in hematologic parameters, including white blood cell, platelet count, platelet indices, the platelet to lymphocyte and neutrophil to lymphocyte ratios in patients with early and advanced stages of epithelial ovarian cancers. MATERIALS AND METHODS The study included 100 patients with epithelial ovarian cancer who underwent primary staging exploratory laparotomy. Preoperative hematologic parameters, tumor histopathologic type, grade, stage and serum CA-125 levels were retrospectively analyzed. These parameters were compared between the patients with early (stage I-II) and advanced (stage III-IV) ovarian cancer. RESULTS White blood cell count and platelet indices, including mean platelet volume, platelet distribution width and platelet crit did not show a statistically significant difference between groups with early and advanced ovarian cancer. However, the neutrophil to lymphocyte ratio, platelet count, the platelet to lymphocyte ratio and CA-125 level showed a statistically significant difference between the two groups (p<0.05, p<0.01, p<0.001, p<0.01 respectively). CONCLUSIONS It was found that the neutrophil to lymphocyte ratio, platelet count and the platelet to lymphocyte ratio increased with the increasing stage of ovarian cancer. Furthermore, it was seen that the platelet to lymphocyte ratio is an independent prognostic factor related to the stage of epithelial ovarian cancer.

Do Leukocyte and Platelet Counts Have Benefit for \Preoperative Evaluation of Endometrial Cancer?

PURPOSE The aim of this study was to investigate the association between preoperative leukocyte and platelet counts and the stage of the disease in patients with endometrial cancer. MATERIALS AND METHODS Data for 100 patients undergoing total abdominal hysterectomy and bilateral salpingoophorectomy for benign uterine diseases and 177 patients surgically staged for endometrial cancer at Ondokuz Mayis University, Department of Gynecology and Obstetrics between 2005 and 2013, with preoperative complete blood count in the week prior to surgery including WBC, platelet count, pathologic evaluation for both benign and malign endometrium lesions, tumor stage and presence of lymphovascular space invasion (LVI), were retrospectively analyzed. RESULTS The preoperative leukocyte count was significantly higher in patients with endometrial cancer when compared to the patients with benign diseases. However, there were no significant differences in platelet counts between the groups. Patients with advanced stage endometrial cancer had higher preoperative leukocyte counts when compared to the early stage disease whereas there was no difference in platelet count. Multivariate regression analysis identified preoperative leukocytosis as an independent prognostic factor for endometrial cancer. The optimal cut-off point for WBC was calculated as 10,500 to differentiate stage 1-2-3 and 4 with 88.9% sensitivity and 86.3% specificity (AUC: 0.901, 95% CI: 0.829-0.973, p<0.001, PPV: 25.8%, NPV: 99.3%). CONCLUSIONS Preoperative leukocytosis is independently associated with advanced endometrial cancer.

Comparison of maternal serum levels of interleukin-10, interleukin-12, and interleukin-2 in normal and preeclamptic pregnancies

OBJECTIVE The aim of this study was 2 fold: (1) to compare the maternal serum levels of IL-10, IL-12, and IL-2 in preeclamptic and normal pregnant women, and (2) to study the serum levels of these cytokines in preeclamptic pregnancies with and without intrauterine growth retardation. STUDY DESIGN Forty women with singleton pregnancies complicated by preeclampsia (32 severe and 8 mild) and 29 normotensive healthy pregnant women were included in the study. Preeclamptic patients were further divided into 2 groups according to the presence or absence of intrauterine growth retardation. Maternal serum levels of IL-10, IL 12, and IL-2 were compared between these groups using enzyme-linked immunosorbent assays. RESULTS Maternal serum levels of IL-10 were significantly higher in the preeclampsia group than in controls (p<0.001). There were no statistically significant differences in maternal serum concentrations of IL-2 and IL-10 between the study and control groups (p>0.05). Serum levels of IL-2 and IL-10 in the patients with preeclampsia complicated by IUGR were elevated in comparison with the uncomplicated preeclampsia group. These differences were statistically significant (p<0.05 for both). CONCLUSIONS IL-10 may be involved in the pathologic process of preeclampsia. Increased serum levels of IL-10 and IL-2 in preeclampsia complicated with IUGR suggests a possible role of these cytokines in IUGR.

Platelet Indices May be Useful in Discrimination of Benign and Malign Endometrial Lesions, and Early and Advanced Stage Endometrial Cancer

BACKGROUND The aim of this study was to investigate the predictive value of white blood cells (WBC), the neutrophil to lymphocyte ratio (NLR), platelet indices including mean platelet volume (MPV), platelet distribution width (PDW), platelet crit (PCT) and platelet to lymphocyte ratio (PLR) in discrimination between benign and malign endometrial lesions, and early and advanced stage endometrial adenocarcinomas. MATERIALS AND METHODS Data for 105 patients undergoing total abdominal or vaginal hysterectomy for benign uterine diseases and 114 patients surgically staged for endometrium adenocarcinoma at Ondokuz Mayis University, Department of Gynecology and Obstetrics, between 2008 and 2014, were collected. Parameters were preoperative and postoperative complete blood counts in the week prior to surgery with differentials including WBC, platelet count, platelet indices (MPV, PCT, PDW), NLR and PLR. Pathologic evaluations for both benign and malign endometrium lesions, grade of endometrium adenocarcinoma, tumor stage, presence of lymphovascular space invasion (LVI) were retrospectively analyzed. RESULTS Regarding definitive factors in discriminating patients with endometrium cancer from those with benign diseases, MPV was significantly increased in the malign group whereas there was a significant decrease in the PDW value compared to the benign group. The best cut-off value in differentiation of the benign and malign groups, malign cases were found to increase over the value of 7.54 for MPV, and under 37.8 for PDW. When definitive factors in discrimination of early stage endometrium cancer from advanced stage disease and LVI in the malign group were evaluated according to the ROC analysis, no significant relation was detected between blood parameters and the stage and the LVI of the disease. CONCLUSIONS MPV and PDW may have predictive value in the discrimination of benign and malign endometrium diseases. Nevertheless, since there have been few reports on this topic, further large-scale prospective studies are necessary.

Serum VEGF and PGF may be significant markers in prediction of severity of preeclampsia.

Abstract Objective: The aim of this study evaluate the value of vascular endothelial growth factor (VEGF) and placental growth factor (PGF) serum levels in prediction of preeclampsia, severity and onset time of the disease. Methods: Twenty five placentas of pregnant women diagnosed with preeclampsia (15 severe preeclampsia, 10 mild preeclampsia) and peripheral venous blood samples were collected. The placental and serum levels of VEGF and PGF were measured. Results: VEGF level was significantly higher in cases and the optimal cut-off point was calculated as 600.5 to differentiate the cases and the controls, with 64% sensitivity and 100% specificity. There was a significant increase in median serum level of VEGF in severe cases compared to the mild cases and the controls. The optimal cut-off point for VEGF was calculated as 673.5 to differentiate mild and severe cases, with 93.3% sensitivity and 90% specificity. Whereas, PGF was significantly lower in severe cases than that in the mild cases and controls. The optimal cut-off point for PGF was calculated as 16.1 to differentiate mild and severe cases, with 66.7% sensitivity and 100% specificity. Conclusion: VEGF and PGF may be significant markers in prediction of severity of preeclampsia, and VEGF may also be valuable in prediction of preeclampsia.

Does Surgical Menopause Affect Sexual Performance Differently from Natural Menopause

INTRODUCTION Hysterectomy is the most common major gynecologic operation, together with bilateral salpingo-oophorectomy in the majority of women over the age of 45. AIM To investigate whether surgical menopause affects female sexual performance differently from natural menopause. METHODS The study included 121 women who had undergone surgical menopause and 122 women who had undergone natural menopause. All the women had similar economic, sociocultural, and personal demographic profiles, had been postmenopausal for at least 1 year, and were between the ages of 45 and 65. The women were asked to complete a six-question survey of sexual performance parameters (sexual desire, coital frequency, arousal, orgasm frequency, dyspareunia, and vaginal lubrication). These sexual performance parameters were compared between the surgical and natural menopause groups. RESULTS With the exception of vaginal lubrication, sexual performance parameters were not statistically different between the two groups (P > 0.05). Vaginal lubrication in the surgically menopausal group was lower than in the naturally menopausal group (P < 0.05). Serum dehydroepiandrosterone sulphate, prolactin, and thyrotropin levels were not statistically different between the groups (P > 0.05), whereas serum estradiol and total testosterone levels in the surgically menopausal group were lower than those of the naturally menopausal group (P < 0.05). CONCLUSION The results of this study showed that surgical menopause did not affect female sexual performance differently from natural menopause, with the exception of vaginal lubrication.

Markedly elevated serum alkaline phosphatase level in an uncomplicated pregnancy.

In normal pregnancy, although maternal serum alkaline phosphatase increases and reaches the two-fold of non-pregnant serum level, above this level, hepatic, renal, osteal diseases and malignancies should be kept in mind. We report a case of 28-year-old pregnant woman with increased maternal serum level of alkaline phosphatase activity (17-fold) due to an increased level of placental isozyme. She delivered vaginally a healthy female baby. After delivery, maternal serum alkaline phosphatase activity returned to normal reference range. The aim of this case report is to show this exaggerated isozyme activity of alkaline phosphatase in pregnancy, and to differentiate it from other causes of elevated level of alkaline phosphatase.
