Circulating serum miR-200c and miR-34a-5p as diagnostic biomarkers for endometriosis.

OBJECTIVE: Endometriosis is defined by the presence of endometrial glands and stroma grow in areas outside the uterus. A simple blood test for endometriosis-specific biomarkers would offer a more timely accurate diagnosis of the disease and could lead to earlier treatment intervention. Alterations in microRNA (miRNA) levels in blood may reflect changes during normal physiologic processes and have been related to several pathologic conditions, including gynecologic diseases. In the present study, we aim to evaluate the level of serum miR-34a-5p and miR-200c from women with and without endometriosis, and to explore the potential of miRNAs as reliable non-invasive biomarkers in the diagnosis of endometriosis. METHODS: Expression levels of miRNAs were performed by quantitative real-time polymerase chain reaction (qRT-PCR). Serum cancer antigen 125 (CA-125) levels were analyzed by autoanalyzer. RESULTS: miR-34a-5p expression levels were decreased and miR-200c expression levels were increased in the endometriosis patients compared to the control group. According to the areas under the ROC curve (AUC) values, miR-200c and miR-34a-5p may serve as biomarkers for the diagnosis of endometriosis. Serum miR-34a-5p and miR-200c had a sensitivity of 78.95 % and 100 % and a specificity of 49.12 % and 100 %, respectively, for the detection of endometriosis. CONCLUSION: Serum miRNAs may provide a promising opportunity for diagnosis of endometriosis. Understanding the role of circulating miRNAs will serve a better comprehension of the systemic effects of endometriosis and offer options for new treatments. It is clear that more work is needed in this area.

Determination of PD-1 expression in peripheral blood cells in patients with endometriosis.

In patients with endometriosis, ectopic endometrial tissues can escape from immune system control and survive in other tissues. The pathophysiology of endometriosis is still not fully understood. In this study, we aimed to clarify the pathophysiology of endometriosis, which is thought to be a benign but infiltrative cancer type, which has many similarities with cancer biology by determining PD-1 expression in patients with endometriosis. In this study, n = 73 cases who underwent surgery or examination at the Obstetrics and Gynecology Clinic of Sivas Cumhuriyet University Faculty of Medicine and diagnosed as endometriosis in the biopsy material taken with the pre-diagnosis of endometriosis constituted the patient group. The control group consisted of n = 64 healthy subjects without concomitant malignancy or chronic inflammatory disease. Venous whole blood samples were obtained from the study groups. PD-1 and PD-L1 levels were determined by the ELISA method from serum and plasma samples. PD-1 gene expression level was determined by RT-PCR. The PD-1 level was found to be approximately 350 ± 150 ng/L and 45 ± 17 ng/L in endometriosis and control group, respectively. While the PD-L1 level was approximately 760 ± 108 ng/L in the patients, this level was 140 ± 14 ng/L in the controls. According to the RT-PCR results, the expression of the PD-1 gene 10 times higher compared to the controls. Conclusion: The identified increase of PD-1 levels and gene expression in endometriosis groups show that immunotherapy may be used in the treatment of endometriosis.

STOX1 gene Y153H polymorphism is associated with early-onset preeclampsia in Turkish population.

Preeclampsia (PE) is a disease of pregnancy that causes of maternal and prenatal morbidity worldwide. Studies indicate that variations in STOX1 gene may be a direct risk factor to PE but controversial results regarding the relationship of Y153H variation in the second exon of STOX1 gene with PE have been ongoing since 2005. The aim of this study was to identify if there is any correlation between Y153H polymorphisms and PE in Turkish preeclampsia patients. We performed polymerase chain reaction- restriction fragment lengthpolymorphism(PCR-RFLP) analysis in 500 pregnant women, of whom 373 pregnant women with early onset PE (EOPE) and 500 normal pregnant women. The relationship between STOX1 Y153H polymorphism and EOPE/LOPE was evaluated by statistical analysis. We found that STOX1 Y153H polymorphism is a risk factor for EOPE (p = 0.03). The odds ratio was 1,45 (CI 95% = 1,03-2,05). No relationship between STOX1 Y153H polymorphisms and LOPE (p = 0.13) was found. STOX1 gene Y153H polymorphism is associated with the risk ofearly onset of pre-eclampsiain a Turkish population. The results provide further evidence of the role of STOX1 in the pathophysiology of this disease.

The role of two common FOXP3 gene promoter polymorphisms in preeclampsia in a Turkish population: a case-control study.

Preeclampsia (PE), which occurs in approximately 5% of pregnancies worldwide and constitutes clinically serious complications in 2-3%, is one of the leading causes of maternal and prenatal morbidity and mortality. Recent studies report that regulatory T (Treg) cells, which act as immunosuppressant, are associated with PE. It is clearly defined that FOXP3/Scurfin (Forkhead Box P3) is involved in the development and function of Tregs. However, there are different conclusions regarding the relationship between PE and FOXP3 gene polymorphisms for different populations. For this reason, in this study we investigate the association between FOXP3 gene promoter region polymorphisms and PE in a Turkish population 500 PE patients and 500 healthy pregnant women. Blood samples taken from pregnant women were studied by PCR-RFLP method. As a result, rs2232365 polymorphism was significantly associated with disease (p < .0001) while no significant association was found between rs3761548 polymorphism and the disease (p = .17). Based on these results, it is though that FOXP3 rs2232365 polymorphism may be predisposed to PE development in terms of Turkish population. However, further and functional studies are needed in terms of other polymorphisms and mutations.IMPACT STATEMENTWhat is already known on this subject? A number of recent publications suggest that Tregs may play a role in the pathogenesis of PE. It is known that a stable and high FOXP3 expression is required to maintain the suppressive T cell function of Tregs. Down regulation of FOXP3 in PE has been reported in many previous studies, but the mechanism is still uncertain.What do the results of this study add? Our study has examined two FOXP3 promoter region polymorphisms in terms of Turkish population for the first time. Rs2232365 polymorphism associated with the disease in heterozygous genotype.What are the implications of these findings for clinical practice and/or further research? It has been shown that FOXP3 gene promoter region polymorphisms may be associated with PE for Turkish population. Our results can be a guide for more detailed statistical evaluations and functional studies.

Genetic variants in the microRNA machinery gene (Dicer) have a prognostic value in the management of endometrial cancer.

AIM: Although several associations were found between Dicer rs3742330 single nucleotide polymorphism (SNP) and development and prognosis of some epithelial cancers, relationship between the SNP rs3742330 and endometrial cancer (EC) has not yet been studied. We aimed to investigate the prognostic role of rs3742330 SNP of Dicer gene in EC patients. SUBJECTS AND METHODS: A total of 80 EC patients and 80 control subjects included in the study. Real-time polymerase chain reaction and the allele discrimination technique was used for genotyping of rs3742330 SNP. RESULTS: There was no significant difference between EC patients and control subjects with regard to the genotype and allele frequencies for Dicer rs3742330 SNP (P > 0.05). Despite Dicer rs3742330 SNP had no prognostic value in terms of stage, grade, lymphovascular invasion, myometrial invasion, tumor size, and histopathology; malignant peritoneal cytology has been detected higher in the patients bearing AA genotype compare with AG genotype (P = 0.023). Higher recurrence rate and shorter time to recurrence were found in patients bearing AG and GG genotype compare with AA genotype (P = 0.009). CONCLUSION: Dicer rs3742330 AG and GG genotypes may have the potential to be used as a predictor of poor prognosis in the management of EC case.

Primary Sjögren's Syndrome Adversely Affects the Female Sexual Function Assessed by the Female Sexual Function Index: A Case-Control Study.

OBJECTIVES: This study aims to evaluate the sexual function of females with primary Sjögren's syndrome (pSS) in comparison to healthy females by using the Female Sexual Function Index (FSFI). PATIENTS AND METHODS: This case-control study included 31 female patients (mean age 46.0±10.2 years; range 30 to 68 years) with pSS and 27 healthy females (mean age 44.2±8.5 years; range 30 to 55 years) as control group. The sexual function of the participants was assessed by 19-item FSFI. RESULTS: Mean duration of pSS in the patient group was 35.9 months (range 3 to 264 months). Significantly higher number of pSS patients reported positive history for vaginal infection compared to controls (n=26, 83.9% vs. n=7, 25.9%, respectively; p<0.001) without any difference in endocervical culture result. Cervical smear assessment revealed more inflammation and atrophy in patient group compared to control group (p=0.001). Mean FSFI total score was significantly lower in patient group than control group (18.9±9.9 vs. 25.1±5.1, respectively; p=0.004). Similarly, five out of six domains of FSFI -arousal, lubrication, orgasm, satisfaction, and pain- were significantly lower in patient group. FSFI total and subscale scores, except for pain, were found to be negatively correlated with duration of pSS. CONCLUSION: The pSS causes sexual dysfunction in female patients. Furthermore, as disease duration increases, female sexual function decreases. Clinical management of female patients with pSS should cover the assessment of their sexual functionality and taking the necessary precautions to maintain satisfactory quality of life and treatment outcome.

Hypogastric artery ligation for obstetrical hemorrhage: clinical experience in a tertiary care center.

BACKGROUND/AIM: Several authorities advocate the use of hypogastric artery ligation (HAL) in the treatment of cases of obstetrical hemorrhage related to uterine atony or placenta accreta. We assessed the morbidity and mortality of patients who underwent HAL as a component of emergency procedures to control life-threatening uterine bleeding in a tertiary-care university hospital. MATERIALS AND METHODS: In this retrospective study, the clinical data of 24 eligible patients who underwent HAL between 2010 and 2013 in a university hospital to prevent or control severe uterine bleeding were collected and analyzed with regard to intraoperative and postoperative findings. RESULTS: In the study population, there were nine patients with uterine atony managed without hysterectomy after HAL and there were 15 patients with placenta previa complicated with placenta accreta after HAL. Of these 15 patients, seven underwent hysterectomy and eight were managed without hysterectomy. Overall, the clinical features of the patients managed with or without hysterectomy were similar for patients with uterine atony and placenta previa. CONCLUSION: We suggest that if HAL is performed in a surgical setting as mentioned in this study, it may be a life-saving and fertility-sparing procedure.

Multicenter analysis of gestational trophoblastic neoplasia in Turkey.

BACKGROUND: To evaluate the incidence, diagnosis and management of GTN among 28 centers in Turkey. MATERIALS AND METHODS: A retrospective study was designed to include GTN patients attending 28 centers in the 10-year period between January 2003 and May 2013. Demographical characteristics of the patients, histopathological diagnosis, the International Federation of Gynecology and Obstetrics (FIGO) anatomical and prognostic scores, use of single-agent and multi-agent chemotherapy, surgical interventions and prognosis were evaluated. RESULTS: From 2003-2013, there were 1,173,235 deliveries and 456 GTN cases at the 28 centers. The incidence was calculated to be 0.38 per 1,000 deliveries. According to the evaluated data of 364 patients, the median age at diagnosis was 31 years (range, 15-59 years). A histopathological diagnosis was present for 45.1% of the patients, and invasive mole, choriocarcinoma and PSTTs were diagnosed in 22.3% (n=81), 18.1% (n=66) and 4.7% (n=17) of the patients, respectively. Regarding final prognosis, 352 (96.7%) of the patients had remission, and 7 (1.9%) had persistence, whereas the disease was mortal for 5 (1.4%) of the patients. CONCLUSIONS: Because of the differences between countries, it is important to provide national registration systems and special clinics for the accurate diagnosis and treatment of GTN.

Abdominal Blockage of Iliohypogastric and Ilio-inguinal Nerves for Management of Post-Caesarean Pain: A Novel Method

Objective. The aim of this study was to compare pain relief after caesarean section achieved by an intra-abdominal iliohypogastric and ilio-inguinal (IHII) nerve block with levobupivacaine with that in patients given a placebo. Study design. A total of 60 healthy women scheduled for caesarean delivery under general anaesthesia were enrolled in the study. The patients were randomised to an abdominal IHII nerve block with levobupivacaine (levobupivacaine group) or administration of saline (placebo group). Instead of the classic percutaneous method; the block was administered intra-operatively from the peritoneal aspect. Scores on a visual analogue scale (VAS) at 2; 6; 12 and 24 hours; adverse effects; morphine consumption and success of blockage by a pinprick test were recorded.Results. In the levobupivacaine group; the pinprick test showed there to be successful bilateral block in 22 patients and unilateral block in 5; while the block failed in 3. No block was recorded in the placebo group. When morphine consumption at 12 and 24 hours were compared; consumption was found to be significantly low for both time points in the levobupivacaine group. VAS scores 2; 6 and 12 hours after the operation were also significantly lower in the levobupivacaine group.Conclusion. A block of the IHII nerves from inside the abdomen just before abdominal closure appears to be an effective and safe way of relieving pain after caesarean section

The availability of vaginal hysterectomy in benign gynecologic diseases: a prospective, non-randomized trial.

OBJECTIVE: To determine whether vaginal hysterectomy can be performed in patients with benign gynecologic diseases regardless of uterine size, uterine mobility and previous pelvic surgery and to compare with abdominal hysterectomy. STUDY DESIGN: Between 2003 and 2008, we compared 47 vaginal hysterectomies (VH) with 61 abdominal hysterectomies (AH). We excluded from the study the clinical conditions that mandate abdominal exploration and standard indications for VH such as uterovaginal prolapse. Large, immobile uterus and previous pelvic surgery were not accepted as a contraindication for VH. Demographic characteristics, primary diagnosis, uterine weight, operation time, intraoperative blood loss, complications, and hospital stay and cost in both groups were compared. RESULTS: Groups were similar with respect to demographic features and primary indications. Mean uterine weight and mean operation time were similar in VH and AH groups (258.0 g vs 293.9 g and 93.7 min vs 101.4 min, respectively). Oopherectomy was performed in 44.7% of VH and in 83.6% of AH. Colporrhaphies and/or anti-incontinence surgery were performed in 15 patients in the VH group (31.9%). The intraoperative blood loss was lower in the VH group than the AH group (245.0 mL vs 408.6 mL, P < 0.001). Perioperative complications were increased with AHs. The mean hospital stay and operation cost in the VH group were significantly less than the AH group (P < 0.001). CONCLUSION: This study indicates that vaginal hysterectomy could be performed with less morbidity in patients with benign gynecologic diseases even in large, immobile uterus and previous pelvic surgery.

Ultrasonographic measurement of cervical length in predicting mode of delivery after oxytocin induction.

This study was conducted to explore the value of transvaginal ultrasonographic cervical length measurement, in addition to gestational age, maternal age, parity, Bishop score, and weight of the newborn, in predicting the mode of delivery in pregnancies in which labor is induced with oxytocin at or beyond the 40th gestational week. A total of 73 pregnancies at 40 to 42 weeks of gestation were included. After labor was induced, 29 women delivered vaginally and 44 underwent cesarean section. These groups were compared with respect to possible predictive parameters of delivery outcomes. Student t test, Pearson's correlation analysis, and logistic regression analysis were used for statistical evaluation. Mean preinduction cervical length was 26.8+/-9.9 mm in the vaginal delivery group and 34.2+/-8.1 mm in the cesarean section group (P<.05). Mean maternal age, parity, and Bishop score were significantly higher and mean weight of the newborn was significantly lower in the vaginal delivery group. Cervical length measurements showed a significant negative correlation with Bishop scores (r=-.584; P<.05). Logistic regression analysis revealed that Bishop score (likelihood ratio=.472; 95% confidence interval=.338-.658; P<.05) and weight of the newborn (likelihood ratio=1.002; 95% confidence interval=1.00007-1.003; P<.05) were significant independent predictors of the route of delivery. According to the results of this study, maternal age, parity, Bishop score, cervical length, and weight of the newborn all might affect the mode of delivery after labor induction. Bishop score, although a subjective measure, must be considered an important component of preinduction evaluation.
