RESUMEN

BACKGROUND: Contradictory findings on sexual health in women with Mayer-Rokitansky-Kuester-Hauser syndrome (MRKHS) after vaginal reconstruction point toward the need for more profound assessment of this subject, particularly as it is still unclear what constitutes sexual well-being, especially genital self-image or sexual self-esteem, in women with MRKHS and neovagina. AIM: The aim of this qualitative study was to assess individual sexual health and sexual well-being in the context of MRKHS after vaginal reconstruction, with an emphasis on genital self-image, sexual self-esteem, sexual satisfaction, and coping with MRKHS. METHODS: Qualitative semistructured interviews were conducted with women with MRKHS after vaginal reconstruction (n = 10) with the Wharton-Sheares-George surgical method and a matched control group without MRKHS (n = 20). Women were surveyed about their previous and current sexual activities, perception of and attitudes toward their genitals, disclosure to others, coping with the diagnosis, and perception of surgery. Data were analyzed through qualitative content analysis and compared with the control group. OUTCOMES: The primary outcomes of the study were major categories, such as sexual satisfaction, sexual self-esteem, genital self-image, and dealing with MRKHS, as well as subcategories related to the content analysis. RESULTS: Although half the women in the present study indicated that they were coping well with their condition and were satisfied with sexual intercourse, most felt insecure about their neovagina, were cognitively distracted during intercourse, and showed low levels of sexual self-esteem. CLINICAL IMPLICATIONS: A better understanding of expectations and uncertainties regarding the neovagina might help professionals to support women with MRKHS after vaginal reconstruction to increase sexual well-being. STRENGTHS AND LIMITATIONS: This is the first qualitative study focusing on individual aspects of sexual well-being, especially sexual self-esteem and genital self-image, in women with MRKHS and neovagina. The qualitative study indicates good interrater reliability and data saturation. The limitations of this study include the inherent lack of objectivity resulting from the method but also the fact that all the patients had a particular surgical technique, consequently resulting in limited generalizability of these findings. CONCLUSIONS: Our data indicate that integrating the neovagina into the genital self-image is a prolonged process that is essential for sexual well-being and should thus be the focus of sexual counseling.

RESUMEN

PURPOSE: To investigate a possible influence of repetitive micro-traumata on the ovaries in the course of oocyte retrieval during IVF/ICSI treatment on serum anti-Müllerian hormone (AMH) levels. METHODS: The study included retrospectively collected data from women who underwent three or more consecutive IVF/ICSI treatments between 2007 and 2017. The primary endpoint of the study was to evaluate changes in serum AMH levels on cycle days 1-3 during the course of repetitive IVF/ICSI treatments. RESULTS: A total of 125 patients were included in this study. Median AMH levels before the first, second and third IVF/ICSI cycles were 3.8 ng/mL (IQR 1.8-7.1), 3.3 ng/mL (IQR 1.8-6.1) and 3.0 ng/mL (IQR 1.6-5.3), respectively (p = n.s.). In patients who underwent IVF/ICSI due to polycystic ovary syndrome (PCOS), we found a significant decrease in AMH serum levels between the first [AMH 9.7 ng/mL (IQR 7.4-14.4)] and the third [AMH 5.3 ng/mL (IQR 3.3-10.4)] IVF/ICSI cycles (p = 0.026). When performing a generalized linear model, we found PCOS to be an independent predictor for serum AMH decrease during the course of three oocyte retrievals (p < 0.001). CONCLUSIONS: When comparing the indications for IVF/ICSI, we observed a significant decrease in AMH serum levels after repetitive oocyte retrievals only in women with PCOS, while the decrease in AMH was not significant in patients with tubal factor, endometriosis, male factor and unexplained infertility. This finding leads us to hypothesize that repetitive micro-traumata on the ovarian cortex might diminish/normalize functional ovarian reserve in women with PCOS. Further prospective studies are highly warranted to allow firm conclusions.

RESUMEN

The role of micronutrients in fertility has recently gained increased attention. We aimed to test the impact of a standardized, multinutrient supplementation on outcomes after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) in a pilot study. One hundred women undergoing IVF/ICSI were prospectively included and randomized to receive either a multinutrient supplementation named PROfertil® female that included folic acid, selenium, vitamin E, catechins, glycyrrhizin, diosgenin, damiana and omega-3-fatty acids (study group; n = 50), or 400 µg folic acid (control group; n = 50). Outcome parameters were embryo quality on day 3 after oocyte retrieval (good quality vs. poor quality) and the clinical pregnancy rate. In an intention-to-treat analyses, a higher rate of women with at least one good quality embryo (with at least 6 cells and a fragmentation rate <20%) were found for the study (29/50, 58.0%) compared to the control group (18/50, 36.0%; p = 0.045 in chi-square test; relative risk 1.611, 95% CI 1.009-2.597). In conclusion, a multinutrient supplementation that includes folic acid, selenium, vitamin E, catechins, glycyrrhizin, diosgenin, damiana and omega-3-fatty acids seems beneficial in terms of embryo quality.

RESUMEN

PURPOSE: Endometriosis has an incidence reaching up to 50% in infertile women. Cytokine-mediated immune responses seem to play an important role in endometriosis pathogenesis, but still the etiology and pathophysiology remain unclear. In the current study we tried to investigate whether there is a relationship between IL-10 genetic polymorphism, serum levels of IL-10 and the presence of advanced endometriosis. METHODS: The presence of IL-10 592C/A, 819T/C, 1082G/A promoter polymorphisms and IL-10 serum levels were investigated in advanced endometriosis patients compared to healthy controls. Genomic DNA was extracted from peripheral blood leukocytes and further analyzed by PCR. RESULTS: IL-10 serum levels were higher in endometriosis group compared to controls (1.48, 0.68, p < 0.001). We have observed an association between IL-10 592C/C and 819C/C genotypes, presence of C alleles and an increased risk of endometriosis. No difference was observed in IL-10 serum levels corresponding to different alleles or genotypes. CONCLUSION: Our results suggest that IL-10 592A/C and 819T/C promoter polymorphisms confer susceptibility to advanced endometriosis. No associations were found between the IL-10 1082A/G polymorphism and susceptibility to advanced endometriosis.

RESUMEN

BACKGROUND: To identify predictors of paracentesis in women with severe ovarian hyperstimulation syndrome (OHSS). METHODS: In a retrospective cohort study, we assessed patient characteristics and outcome measures of women with severe OHSS Golan grade II/III from 1996 to 2010 using univariate and multivariate analyses with the number of paracenteses as the main outcome. RESULTS: Three hundred ninety four women with OHSS Golan grade II (n = 40) and grade III (n = 354) were included in the study. Paracentesis was performed in 108/394 (27%) of these women. One paracentesis was performed in 63 (16%), 2 paracenteses in 26 (6%), and ≥3 paracenteses 19 (5%) women, respectively. No thrombotic or cerebrovascular morbidity occurred. The mortality of the cohort was 0/394 (0%). In a univariate analysis, late onset OHSS (p = 0.02), pregnancy (p < 0.001), human chorionic gonadotropin use (p = 0.02), ovarian diameter (p = 0.006), and elevated serum levels of alanine aminotransferase (p < 0.001), hematocrit (p < 0.001), leucocytes (p < 0.001), thrombocytes (p < 0.001), and uric acid (p < 0.001) were associated with paracentesis. In a multivariate logistic regression analysis, only alanine aminotransferase (OR 1.006; 95% CI 1.001-1.01) and hematocrit (OR 1.16; 95% CI 1.05-1.27) were independently associated with paracentesis. CONCLUSION: Alanine aminotransferase and hematocrit at initial presentation are independent predictors of paracentesis.

RESUMEN

BACKGROUND: The influence of embryo loading time (ELT) and the time interval between embryo loading and embryo transfer (TIEL-ET) on the success of IVF/ICSI is unknown. METHODS: In a prospective cohort study, we aimed to ascertain the influence of ELT and TIEL-ET on ongoing pregnancy rate (OPR) and life birth rate (LBR). Data from 603 consecutive embryo transfers between January 2008 and December 2013 were collected. A complete data set including the outcomes of interest OPR and LBR was available for 410 women. The primary outcome was IVF/ICSI success, defined as OPR and LBR. RESULTS: We used univariate and multivariate logistic regression for analysis. In a multivariate analysis, age (odds ratio [OR] 0.94; 95% confidence interval [CI] 0.89-0.99), catheter type (OR 0.45; 95% CI 0.24-0.84), and uterine length (OR 1.03; 95% CI 1.01-1.06), but not ELT and TIELT-ET were independently associated with OPR. Regarding LBR, age (OR 0.93; 95% CI 0.88-0.98), catheter type (OR 0.41; 95% CI 0.22-0.79), and uterine length (OR 1.03; 95% CI 1.01-1.06), but not ELT and TIELT-ET were independent predictors. CONCLUSION: We conclude that speed of embryo transfer is not critical for the success of IVF/ICSI. However, care should be taken to choose catheter types proven to be associated with a high success rate.

RESUMEN

BACKGROUND: To compare the understanding and perceptions of fertility issues among medical and non-medical University students. METHODS: In a prospective case-control study, using a 43 item questionnaire with 5 sections and 43 questions regarding personal data (8 questions), lifestyle factors (9 questions), plans on having children (5 questions), age and fertility (5 questions), and lifestyle and fertility (16 questions), knowledge of fertility and influencing factors, desired age at commencement and completion of childbearing, among male and female medical and non-medical students in their first academic year at Vienna University, Vienna, Austria were evaluated. RESULTS: 340 students were included. 262/340 (77%) participants planned to have children in the future. Medical students (n = 170) planned to have fewer and later children and had a higher awareness of the impact of age on fertility than non-medical students (n = 170; estimated knowledge probability 0.55 [medical students] vs. 0.47 [non-medical students]; F (1, 336) = 5.18 and p = .024 (η p = .015). Gender did not independently affect estimated knowledge probability (F (1, 336) = 1.50 and p = .221). More female and male medical students had a positive attitude towards Assisted Reproductive Technology in case of infertility than non-medical students (47 and 55% vs. 23 and 29%, respectively; p = <.001). Medical students had a healthier lifestyle than non-medical students. A healthy lifestyle and female gender were associated with higher fertility awareness. CONCLUSIONS: Medical students have a higher awareness of fertility issues than non-medical students. Choice of academic study, gender, and personal life style are important factors affecting fertility awareness. These data may be helpful to address knowledge gaps among young non-medical Academics.

RESUMEN

BACKGROUND: To evaluate predictive factors for recovery time from severe ovarian hyperstimulation syndrome (OHSS). METHODS: In a retrospective cohort study, 201 women who were hospitalized for severe OHSS were included. Patients with recurrent OHSS were excluded. All the patients received standardized treatment including intravenous hydration, plasma volume expansion, human albumin, furosemid, subcutaneous heparin, and paracentesis if necessary. The main outcome parameter was recovery time from OHSS. Recovery was defined if a morning hematocrit <40%, rebalance of electrolytes, and serum creatinine <1 mg/dL were reached during the standardized therapy and the patient had not suffered from abdominal pain and discomfort at least for one day without any OHSS-specific infusions or medications. RESULTS: Pregnant patients (n=80, 39.8%) revealed a longer median duration until recovery than non-pregnant patients (n=121, 60.2%; 10 days, IQR 7-13, vs. 8 days, IQR 6-10, respectively; p=0.001). In a generalized linear model, presence of polycystic ovary syndrome before controlled ovarian hyperstimulation (beta=0.3342 +/- 0.1335, p=0.012) and use of hCG for ovulation induction (beta=0.222 +/- 0.1389, p=0.048) were associated with a longer recovery time in pregnant patients. In non-pregnant patients, none of the tested factors was associated with recovery time. CONCLUSIONS: Pregnant patients with severe OHSS needed a significantly longer recovery time than non-pregnant patients. In pregnant patients, presence of polycystic ovary syndrome and ovulation induction with hCG were associated with longer recovery times.

RESUMEN

A case series of haematoperitoneum caused by ovarian bleeding after transvaginal oocyte retrieval (TVOR) is presented and all published cases summarized. In a retrospective case series, four patients with ovarian bleeding after TVOR were included. In addition, a pooled analysis of all published cases (n = 32) who underwent surgical intervention for severe haematoperitoneum caused by ovarian bleeding after TVOR was carried out. Main outcome measures were incidence, risk factors, course and intraoperative findings. In the pooled analysis, the incidence was 0.08%. The first sign of haematoperitoneum was evident in 33.3% within the first postoperative hour, and, cumulatively, in 93.3% within 24 h. The median time between TVOR and surgical intervention was 10 h. In four patients, the ovary could not be preserved, which was associated with a longer time interval between TVOR and the onset of symptoms (median 18 h versus 2.5 h; P = 0.004) as well as between TVOR and surgical intervention (median 21.5 h versus 8.5 h; 0.004). In conclusion, severe haematoperitoneum occurs in 0.08% after TVOR. Late-onset bleeding is common. A longer time interval between TVOR and surgical intervention might put a patient at risk of ovariectomy.

RESUMEN

BACKGROUND: Although most pregnancies after IVF result in normal healthy outcomes, an increased risk for a number of obstetric and neonatal complications, compared to naturally conceived pregnancies, has been reported. While there are many studies that compare pregnancies after assisted reproductive techniques with spontaneously conceived pregnancies, fewer data are available that evaluate the differences between IVF and ICSI-conceived pregnancies. The aim of our present study was, therefore, to compare obstetric and perinatal outcomes in pregnancies conceived after in vitro fertilization (IVF) versus intracytoplasmatic sperm injection (ICSI). METHODS: Three-hundred thirty four women who had become pregnant after an IVF or ICSI procedure resulted in a total of 530 children referred between 2003 und 2009 to the Department of Obstetrics and Gynecology of the Medical University of Vienna, a tertiary care center, and were included in this retrospective cohort study. We assessed maternal and fetal parameters in both groups (IVF and ICSI). The main study outcomes were preterm delivery, the need for neonatal intensive care, and congenital malformations. Moreover, we compared the course of pregnancy between both groups and the occurrence of complications that led to maternal hospitalization during pregnancy. RESULTS: There were 80 children conceived via ICSI and 450 children conceived via IVF.Mean gestational age was significantly lower in the ICSI group (p = 0.001). After ICSI, the birth weight (p = 0.008) and the mean APGAR values after 1 minute and after 10 minutes were lower compared to that of the IVF group (p = 0.016 and p = 0.047, respectively). Moreover, ICSI-conceived children had to be hospitalized more often at a neonatal intensive care unit (p = 0.004). There was no difference in pH of the umbilical artery or in major congenital malformations between the two groups. Pregnancy complications (i.e., premature rupture of membranes, cervical insufficiency, and premature uterine contractions) and the need for maternal hospitalization during pregnancy were found significantly more often after IVF (p = 0.0016 and p = 0.0095, respectively), compared to the ICSI group. CONCLUSIONS: When comparing IVF versus ICSI-conceived pregnancies at a tertiary care center, we found the course of pregnancy to be more complicated after IVF, whereas the primary fetal outcome seemed to be better in this group than after ICSI treatment.

RESUMEN

Background: The use of different definitions and diagnostic approaches of polycystic ovary syndrome (PCOS) and recurrent miscarriage (RM) has led to a wide range of prevalence rates in the literature. Despite the persistent controversy about the factual prevalence of PCOS in RM, a vast number of studies have revealed evidence about their association with each other. The goals of this study were to evaluate the prevalence of polycystic ovarian morphology and PCOS within the RM population, performing meta-analyses with the obtained data from this study, together with previous reports on this topic and evaluating reproductive outcome in women with RM and PCOS. Methods: A retrospective cohort study with 452 women with RM and a meta-analysis were conducted. The main outcome parameter was the prevalence of PCOS in RM patients. Results: In the retrospective study, the prevalence of PCOS in RM was 9.5%. Negative results for the selected risk factors for RM were present in 283 patients (62.6%). From all evaluated possible underlying causes for RM, only the presence of thrombophilic disorders was significantly associated with PCOS (PCOS: 20.9% versus no PCOS: 7.8%, p = 0.010). In the meta-analysis of three studies on PCOS in RM patients, which used the revised Rotterdam criteria for defining PCOS, an estimated pooled prevalence of 14.3% (95% CI: 6.2-24.9) was found. In the retrospective data set, women in the PCOS group revealed significantly higher luteinizing hormone (LH), testosterone, and Anti-Mullerian hormone (AMH) levels than age- and body mass index (BMI)-matched controls with RM negative for the selected risk facotrs (p < 0.05). The rate of further miscarriages was significantly higher in PCOS women than in controls (71.4% versus 53.6%, respectively; p = 0.031). Conclusions: The prevalence of PCOS seems slightly increased in women with RM. Women with PCOS suffering from RM showed a significantly higher risk for further miscarriage and decreased chances of having a life birth of about 18% which did not reach statistical significance. Therefore, we assume that PCOS plays a moderate role in RM.

RESUMEN

Recurrent miscarriage is known to affect 0.5-2% of pregnant women, and the standard investigative protocol fails to identify a specific cause in 50% of cases. Progesterone, a key hormone in pregnancy maintenance, has been used to support early pregnancy for decades. A growing body of considerable evidence indicates that in addition to women with luteal phase defects, women with idiopathic recurrent miscarriage may benefit from progestogen treatment, as progesterone has been shown to be an essential immunomodulatory agent in early pregnancy. It plays a critical role in the expression, modulation and inhibition of various growth factors, cytokines, cell adhesion molecules and decidual proteins. Some studies have revealed a remarkable improvement in pregnancy outcome after progestogen supplementation in women suffering from recurrent miscarriage. As most studies on this topic are of unsufficient statistical power, further research on the efficacy of progestogen treatment in affected women is required.

RESUMEN

OBJECTIVES: To investigate the association of two common genetic polymorphisms of the gene encoding for endothelial nitric oxide synthase (Nos3), the enzyme catalyzing the production of nitric oxide (NO), with occurrence of the polycystic ovary syndrome (PCOS). METHODS: In a prospective case-control study, we analyzed 2 polymorphisms of the Nos3 gene cluster (Nos 3 exon 7 Glu298Asp and 27-base pair repeat in intron 4 of Nos3) in a series of 210 premenopausal Caucasian women with PCOS and 171 healthy controls using pyrosequencing and PCR, respectively. Women completed a detailed questionnaire and underwent a peripheral venous puncture, ultrasonography, and a standardized oral glucose tolerance test (OGTT). RESULTS: Genotype frequencies were not significantly different among women with PCOS and controls for the exon 7Nos3 and the intron 4Nos3 polymorphism (p=0.3 and 0.2, respectively). CONCLUSIONS: In our series, two common polymorphisms of the Nos3 gene cluster were not associated with occurrence of PCOS.

RESUMEN

INTRODUCTION: Smoking is a serious problem for the health care system. Many of the compounds identified in cigarette smoke have toxic effects on the fertility of both females and males. The purpose of this study was to determine whether smoking affects clinical factors during IVF/ICSI therapy in a single-center reproductive unit. MATERIAL AND METHODS: In a retrospective study of 200 IVF/ICSI cycles, endometrial thickness and the outcome of IVF/ICSI therapy were analyzed. RESULTS: Endometrial thickness was significantly lower in smoking patients than in non-smoking patients (10.4 ± 1.5 mm vs. 11.6 ± 1.8 mm). Age was significantly higher in women who failed to conceive. The total dose of gonadotropins administered was significantly lower in pregnant patients and the highest pregnancy rate was achieved with an rFSH protocol. BMI and number of cigarettes smoked did not influence treatment outcomes in this study. CONCLUSION: We showed that smoking has a negative effect on endometrial thickness on the day of embryo transfer. This may help to further explain the detrimental influence of tobacco smoke on implantation and pregnancy rates during assisted reproduction therapy.

RESUMEN

Interleukin-1 (IL1) is a multifunctional cytokine and IL1-mediated inflammatory processes have been proposed to influence the processes of ovulation, fertilization and implantation. All these parameters are also affected in women with polycystic ovary syndrome (PCOS). This study investigated the association of common polymorphisms of the interleukin-1 genes (IL1A and IL1B) with the occurrence and clinical characteristics of PCOS. We evaluated one polymorphism of the IL1alpha gene (IL1A C[-889]T) and two of the IL1beta gene (IL1B promoter C[-511]T and IL1B exon 5 position +3953) in 105 Caucasian women with PCOS and 102 healthy Caucasian controls by polymerase chain reaction. For the mutated IL1A allele, allele frequencies in women with PCOS and controls were 60% and 46%, respectively, versus 40% and 54%, respectively, for the wild type allele. Allele frequencies in women with PCOS and controls were 59% (54%) and 61% (41%), respectively, for the mutated IL1B promoter (mutated IL1B exon 5) and 41% (46%) and 39% (59%), respectively, for the wild type alleles. Presence of a polymorphism in the interleukin-1alpha but not the interleukin-1beta gene was found to correlate with the occurrence of PCOS (p=0.04; odds ratio 1.8). The serum level of FSH and subsequent LH/FSH ratio correlated with the polymorphism of IL1A within the PCOS group (p=0.005 and 0.01, respectively). We have shown that a common polymorphism of the interleukin-1alpha but not interleukin-1beta gene is associated with the presence of PCOS and with clinical parameters of women affected by this condition.

RESUMEN

PROBLEM: Various autoimmunologic mechanisms have been shown to be involved in recurrent pregnancy loss (RPL). This study aimed to evaluate whether women with RPL have elevated serum levels of common autoimmunologic parameters. METHOD OF STUDY: Serum levels of antinuclear antibodies (ANAs) were measured in 114 women with RPL, and 107 healthy controls using a qualitative immunometric enzyme immunoassay, serum levels of IgG class autoantibodies against histone, IgG class autoantibodies against nucleosomes, and IgG class autoantibodies against double-stranded (ds) DNA were measured by quantitative enzyme immunoassays. RESULTS: No differences were ascertained regarding serum levels of ANAs (P=.9), serum levels of antibodies against histones (P=.1), antibodies against nucleosomes (P=.4) and antibodies against dsDNA (P=.6) between women with RPL and healthy controls. No associations were found between serum levels and clinical characteristics of affected women. CONCLUSION: Our study shows that serologic parameters of autoimmunity are not elevated in women with RPL and are not associated with clinical characteristics of affected women.

RESUMEN

Etiologic factors for recurrent miscarriage (RM) include autoimmune diseases, the most frequently antiphospholipid syndrome and thyroiditis. Some women who suffer from RM might also have an altered immune system. We aimed to evaluate possible associations between anti-thyroid and anti-phospholipid antibodies in women with RM. In a retrospective case series 1 on 156 women with RM, major outcome parameters were antibodies against cardiolipin, ß2-glycoprotein I, thyreoperoxidase (TPO-Ab), and thyroglobulin (TG-Ab). Significant (p<0.05) positive correlations were found between TPO-Ab and TG-Ab (r=0.577), TPO-Ab and IgG anti-cardiolipin antibodies (r=0.284), TPO-Ab and IgG anti- ß2-glycoprotein I antibodies (r=0.196), and TG-Ab and IgG anti-cardiolipin antibodies (r=0.193), as well as between all types of anti-phospholipid antibodies. Women with both increased TPO-Ab and TG-Ab levels revealed higher (p<0.001) IgG anti-cardiolipin and IgG anti-ß2-glycoprotein I antibodies. Anti-thyroid antibodies were linked to anti-phospholipid antibodies and should be in the focus of future research on RM.

RESUMEN

Oral contraceptives (OCs) have been shown to effectively treat acne. Clinical trials of various doses of ethinyl estradiol (EE) combined with progestins such as levonorgestrel, desogestrel, norgestimate, gestodene, cyproterone acetate and drospirenone in monophasic, triphasic and combiphasic formulations used to treat acne in women are reviewed here. Open-label and comparative studies beginning in the 1980s were the first to demonstrate objective and subjective reductions in the incidence of acne, severity of existing acne and seborrhea. Placebo-controlled trials have corroborated these findings with a trend toward effective acne treatment with declining doses of EE. Significant reductions in total, inflammatory and noninflammatory lesions compared with placebo have been demonstrated with an OC containing the low dose of 20 microg of EE. Collectively, these findings support the use of low-dose OCs for the treatment of acne.

RESUMEN

Endometriosis is a benign but troublesome gynecological condition, characterized by endometrial-like tissue outside the uterine cavity. Lately, the discovery and validation of noninvasive diagnostic biomarkers for endometriosis is one of the main priorities in the field. As the disease elicits a chronic inflammatory reaction, we focused our interest on two factors well known to be involved in inflammation and neoplastic processes, namely, soluble CD40 Ligand and CXCL1, and asked whether differences in the serum levels of sCD40L and CXCL1 in endometriosis patients versus controls can serve as noninvasive disease markers. A total of n = 60 women were included in the study, 31 endometriosis patients and 29 controls, and the serum levels of sCD40L and CXCL1 were measured by enzyme-linked immunosorbent assay. Overall, there were no statistically significant differences in the levels of expression of both sCD40L and CXCL1 between patients and controls. This study adds useful clinical data showing that the serum levels of the soluble factors sCD40L and CXCL1 are not associated with endometriosis and are not suitable as biomarkers for disease diagnosis. However, we found a trend toward lower levels of sCD40L in the deep infiltrating endometriosis subgroup making it a potentially interesting target worth further investigation.

RESUMEN

OBJECTIVE: To evaluate the association between a common polymorphism of the Vitamin D receptor gene (VDR) and the timing of female reproductive functions in humans. METHODS: One thousand fifty-eight consecutive women were included in this cross-sectional study. We analyzed the intron 8 Bsm I restriction fragment length polymorphism (RFLP) of VDR on chromosome 12q using a microarray-based system. RESULTS: The presence of the VDR polymorphism did not influence the timing of menarche and natural menopause and was not associated with the number of spontaneous abortions, full term pregnancies (FTP) as well as the total number of pregnancies. Of note, women with at least one mutant allele of VDR were at a significantly decreased risk for experiencing surgical menopause (odds ratio [OR] 0.65, 95% confidence interval [CI], 0.46-0.92, P = 0.02). Smoking and a body mass index (BMI) > 25 were associated with an earlier natural menopause and an increased risk for surgical menopause, respectively. CONCLUSIONS: While no association of a common polymorphism of VDR with the timing of menarche and menopause was ascertained, we found the presence of at least one mutant allele of VDR to be associated with a decreased risk of experiencing surgical menopause, i.e., premenopausal hysterectomy, in a large series of Caucasian women.
