The role of vitamin D in reproductive dysfunction in women - a systematic review

Vitamin D is essential for the proper functioning of the human body. There is also evidence of its strong association with fertility problems in women. This review aims to evaluate the relationship between vitamin D and diseases affecting women's fertility (polycystic ovarian syndrome (PCOS), uterine leiomyomas and endometriosis), and in vitro fertilization (IVF) outcome. A systematic review of the literature was conducted in Scopus and PubMed for relevant English language publications since 1989. Vitamin D influences the functioning of the reproductive system in women and has been associated with PCOS, uterine leiomyomas, endometriosis and in vitro fertilization (IVF) outcome. However, further studies on larger groups of patients are needed to establish what role vitamin D plays in the treatment of female infertility.

Fertility in women of late reproductive age: the role of serum anti-Müllerian hormone (AMH) levels in its assessment

INTRODUCTION

Fertility is referred to the capability for having offspring and can be evaluated by fertility rate. Women's fertility is strictly dependent on individual's age. The fertility peak occurs in the early 20s, and it starts to decline in the third and fourth decades of life (falling sharply after age 35).

AIM

The aim of this work is to review the available data concerning fertility in women of late reproductive age, especially the role of serum anti-Müllerian hormone (AMH) levels.

RESULTS

There are a lot of factors responsible for decrease of fertility in women of late reproductive age. These factors can be classified as oocyte-dependent (decrease in oocyte quantity and quality) and oocyte-independent (reproductive organs [uterus, oviducts] status and general health). Anti-Müllerian hormone (AMH) is a dimeric glycoprotein of the transforming growth factor-β (TGF-β) superfamily produced directly by the ovarian granulosa cells of secondary, preantral, and early antral follicles. It has been used as an ovarian reserve marker since 2002. Anti-Müllerian hormone seems to be the best endocrine marker for assessing the age-related decline of the ovarian pool in healthy women. Evaluation of AMH's predictive value in the naturally aging population is important for counseling women about reproductive planning as well as for treatment planning for women experiencing hormone-sensitive gynecological conditions such as endometriosis and fibroids.

CONCLUSIONS

AMH can be considered as an indicator of fertility in late reproductive age women and pregnancy outcome in assisted reproductive technology cycles. AMH can strongly predict poor response in the controlled ovarian stimulation.

Influence of vitamin D and transforming growth factor β3 serum concentrations, obesity, and family history on the risk for uterine fibroids

OBJECTIVE

To evaluate the influence of 25-hydroxyvitamin D and transforming growth factor β3 (TGF-β3) serum concentrations, weight, and family history on the risk of developing uterine fibroids.

DESIGN

Retrospective cohort study.

SETTING

University hospital.

PATIENT(S)

A total of 188 women, including patients admitted for uterine fibroid surgery (n = 105) as the study group and healthy women of similar age (n = 83) as controls.

INTERVENTION(S)

Medical history and completion of specially designed questionnaire, transvaginal or transabdominal genital ultrasound scan, blood sampling, and measurement of vitamin D and TGF-β3 serum concentrations.

MAIN OUTCOME MEASURE(S)

Evaluation of the impact of family history, vitamin D, and TGF-β3 serum concentrations on the risk of developing uterine fibroids.

RESULT(S)

Mean 25-hydroxyvitamin D serum concentrations were 21.9 ± 8.9 ng/mL and 26.7 ± 11.9 ng/mL in patients with uterine fibroids and controls, respectively. The difference was statistically significant. The TGF-β3 serum concentrations in the fibroid-positive group ranged from 1.20 to 436.15 pg/mL (half the patients had concentrations >16.25 pg/mL). Concentrations in the control group ranged from 0.96 to 49.08 pg/mL (half the women had concentrations of >11.80 pg/mL). The differences were statistically significant. Higher body mass index (BMI) and positive family history were also found to be among the risk factors for uterine fibroids.

CONCLUSION(S)

Our study confirmed higher BMI, positive family history, and lower vitamin D and higher TGF-β3 serum concentrations as risk factors for uterine fibroids.

Prenatal diagnosis of congenital myopathies and muscular dystrophies

Congenital myopathies and muscular dystrophies constitute a genetically and phenotypically heterogeneous group of rare inherited diseases characterized by muscle weakness and atrophy, motor delay and respiratory insufficiency. To date, curative care is not available for these diseases, which may severely affect both life-span and quality of life. We discuss prenatal diagnosis and genetic counseling for families at risk, as well as diagnostic possibilities in sporadic cases.

Next generation sequencing for preimplantation genetic testing of blastocysts aneuploidies in women of different ages

Most of the current preimplantation genetic screening of aneuploidies tests are based on the low quality and low density comparative genomic hybridization arrays. The results are based on fewer than 2,700 probes. Our main outcome was the association of aneuploidy rates and the women's age. Between August-December 2013, 198 blastocysts from women (mean age 36.3+-4.6) undergoing in vitro fertilization underwent routine trophectoderm biopsy. NGS was performed on Ion Torrent PGM (Life Technologies). The results were analyzed in five age groups (<31, 31-35, 36-38, 39-40 and >40). 85 blastocysts were normal according to NGS results. The results in the investigated groups were (% of normal blastocyst in each group): <31 (41.9%), 31-35 (47.6%), 36-38 (47.8%), 39-40 (37.7%) and >40 (38.5%). Our study suggests that NGS PGD is applicable for routine preimplantation genetic testing. It allows also for easy customization of the procedure for each individual patient making personalized diagnostics a reality.

First Pregnancy, Somatic and Psychological Status of a 4-Year-Old Child Born following Annexin V TESA Sperm Separation

Introduction Sperm DNA integrity is a crucial paternal factor affecting fertilization and pregnancy rates, as well as embryo development. Case The present case report describes the successful pregnancy after testicular sperm aspiration (TESA) combined with intracytoplasmic sperm injection (ICSI) (TESA-ICSI) in a couple where the male presented high sperm DNA fragmentation. In order to sort damaged sperm presenting DNA fragmentation, magnetic activated cell sorting (MACS) with annexin V microbeads (MACS Miltenyi Biotec, Teterow, Germany) was used. Conclusion The authors present the first description of a successful medical case using TESA-ICSI annexin V sperm sorting. Additionally, a follow-up of the child at the age of 4 years old was done.

Placenta accreta: review and 3 case reports

Placenta accreta is characterized by excessive penetration of the villi into the myometrium, which obstructs its correct separation during stage III of labor. That in turn leads to a potentially life-threatening maternal hemorrhage. Until recently this pathology has been a rare occurrence but currently it is fifty times more prevalent. Placenta accreta is associated with high morbidity and the risk of maternal death, even despite advances in ultrasonographic diagnostics, well-established surgical treatment, and multi-disciplinary medical care. A dramatic rise in the rates of Cesarean section and intrauterine surgical procedure is considered to be the main factor responsible for the growing incidence of placenta accreta. It is especially frequent in women after a Cesarean section and with placenta previa covering the lower segment. A Cesarean section, combined with hysterectomy and application of various techniques to limit massive bleeding, is usually performed between 34-36 weeks of pregnancy before the onset of labor. Three cases of placenta accreta are presented.

Serum dehydroepiandrosterone sulphate concentration is not a predictive factor in IVF outcomes before the first cycle of GnRH agonist administration in women with normal ovarian reserve

Objective

The aim of our study was to determine whether serum dehydroepiandrosterone sulphate (DHEAS) concentration and the models incorporating it could help clinicians to predict IVF outcomes in women with normal ovarian reserve undergoing their first long protocol.

Study Design

We performed a retrospective analysis of 459 women undergoing cycles of intracytoplasmic sperm injection (ICSI) for the first time in a long GnRH agonist protocol.

Results

Embryo transfer was performed in 407 women (88.7%). The fertilisation rate was 78.6%. The clinical pregnancy rate was 44.8% per started cycle and 50.6% per embryo transfer. Our univariate model revealed that the best predictors of clinical pregnancy were the number of mature oocytes, the number of embryos transferred and the number of good quality embryos, account for the clinical parameters that reflect ovarian reserve the best being AMH level and AFC. DHEAS did not predict clinical pregnancy (OR 1.001, 95% CI, 0.999–1.004). After adjusting for the number of embryos transferred and class of embryos in a multivariate model, the best predictors were age (OR 0.918, 95% CI, 0.867–0.972) and AFC (OR 1.022, 95% CI, 0.992–1.053). Serum DHEAS levels were positively correlated with AFC (r = 0.098, P<0.039) and testosterone levels (r = 0.371, P<0.001), as well as the number of mature oocytes (r = 0.109, P<0.019); serum DHEAS levels were negatively correlated with age (r = -0.220, P<0.001), follicle-stimulating hormone (FSH), (r = -0.116, P<0.015) and sex hormone-binding globulin (SHBG), (r = -0.193, P<0.001).

Conclusions

DHEAS concentration (in addition to the known factors of ovarian reserve) does not predict clinical pregnancy in women with normal ovarian reserve who are undergoing ICSI.

Pharmacological treatment and regional anesthesia techniques for pain management after completion of both conservative and surgical treatment of endometriosis and pelvic adhesions in women with chronic pelvic pain as a mandated treatment strategy

INTRODUCTION

Chronic pelvic pain syndrome occurs in 4-14% of women. Pain pathomechanism in this syndrome is complex, as it is common to observe the features of nociceptive, inflammatory, neuropathic and psychogenic pain. The common findings in women with pelvic pain are endometriosis and pelvic adhesions.

OBJECTIVE

Aim of the study was to test the effectiveness of pharmacological treatment and regional anesthesia techniques for pain control as the next step of treatment after the lack of clinical results of surgical and pharmacological methods normally used in the management of endometriosis and pelvic adhesions.

MATERIALS AND METHOD

18 women were treated between January 2010 - October 2013 in the Pain Clinic of the Department of Anaesthesiology and Intensive Care at the Centre for Postgraduate Education in Warsaw due to chronic pelvic pain syndrome related to either endometriosis or pelvic adhesions. During the previous step of management, both conservative and surgical treatments were completed without achieving satisfactory results. Initial constant pain severity was 3-9 points on the Numeric Rating Scale, while the reported paroxysmal pain level was 7-10. The pharmacological treatment implemented was based on oral gabapentinoids and antidepressants, aided by neurolytic block of ganglion of Walther, pudendal nerve blocks and topical treatment (5% lidocaine, 10% amitriptyline, 10% gabapentin).

RESULTS

In 17 women, a significant reduction of both constant and paroxysmal pain was achieved, of which complete and permanent cessation of pain occurred in 6 cases. One patient experienced no improvement in the severity of her symptoms.

CONCLUSIONS

The combination of pain management with pharmacological treatment, pudendal nerve blocks, neurolysis of ganglion impar (Walther) and topical preparations in cases of chronic pelvic pain syndrome seems to be adequate medical conduct after failed or otherwise ineffective causative therapy.

Late preterm infants - impact of perinatal factors on neonatal results. A clinical study

INTRODUCTION

Infants born between the 34(th) - 36(th) week of pregnancy account for 75% of all preterm infants. Their seemingly slight immaturity is related to serious health problems.

OBJECTIVE

The aim of the study was to analyse perinatal factors that influence the occurrence in infants of such problems as respiratory failure, metabolic problems and early onset sepsis (EOS).

MATERIALS AND METHOD

The material for the study included all mothers and their late preterm infants: 34+0 - 36+6 born in our hospital (a tertiary referral academic centre) in 2010 and 2011. The course of pregnancy and delivery, the type of delivery, applied preventive measures and treatment, as well as demographic data and the clinical state of infants were all analysed. Data from individual documentation of each mother and infant were collected by 5 designated people and data reliability was independently monitored by a random control of the documentation conducted by the supervising person.

RESULTS

A statistically significant relationship between the occurrence of respiratory distress syndrome and infant immaturity, bad state after birth and sepsis in infants were confirmed. Sepsis was more common in the case of vaginal delivery, and coexisted with respiratory distress syndrome. The mother's diseases during pregnancy, a perinatal preventive antibiotic therapy, and possible delivery complications did not influence the infection. Perinatal asphyxia in an infant positively correlated with a Caesarean section and respiratory distress syndrome after birth.

CONCLUSIONS

It is necessary to thoroughly establish the type of delivery of a late preterm infant in order to prevent an infection in the newborn child. The improvement of diagnosis of intrauterine hypoxia may reduce the number of Caesarean sections. The decision about late preterm delivery should be based on indices of the mother's state of health. Premature delivery is related to the occurrence of respiratory distress syndrome in a late preterm infant, although the risk is reduced by the application of an antenatal steroid therapy.

Psychosocial problems of women with stress urinary incontinence

OBJECTIVE

The aim of the study was evaluation of the influence of stress urinary incontinence on women's quality of life.

MATERIAL AND METHOD

The study covered 275 women between 30-65 years of age. The study was conducted using the following tools: Gaudenz Questionnaire, King's Health Questionnaire (KHQ), Female Sexual Function Index (FIFI) Questionnaire, and a questionnaire devised by the authors of the study.

RESULTS

The study shows that the disease has a negative effect on evaluation of the quality of thee women's lives. The symptoms of stress urinary incontinence had a significant influence on the feeling of emotional comfort, social and professional activity of the surveyed women - respectively p= 0.000; p=0.000; p=0.000. Nearly every third woman (28.7%) felt great mental discomfort related to the disease symptoms, 31.7% a considerable discomfort, 33.1% a moderate, and very few women (6.5 %) claimed that the disease had a minimal effect on their emotional state. About two-thirds of the surveyed women (68.7%) were sexually active, and the remaining 31.3% declared the lack of sexual intercourse.

CONCLUSIONS

The occurrence of stress urinary incontinence symptoms affects the quality of life of women, especially their mental state and interpersonal contacts. Most women with the symptoms of stress urinary incontinence fulfill their sexual needs; however, many of them do not feel complete satisfaction with their sex life.

Oxidative stress and total antioxidant status in term newborns and their mothers

The peripartum period and delivery are considered critical for maintaining a balance between the production of free oxygen radicals and functional incompetence of the antioxidant system of a foetus and a neonate.

OBJECTIVE

The aim of the study was to evaluate the oxidoreductive state of mothers and their newborns immediately after delivery and in the first few days after birth.

METHOD

Eighty-five mothers and their healthy, term newborns were included into the prospective study. Total antioxidant capacity (TAC) and thiobarbituric acid reactive substances (TBARS) in maternal placenta and milk, as well as blood and urine of the neonates on the first and third day after birth, were examined.

RESULTS

Elevated levels of TBARS were found in maternal placenta and neonatal blood on the third day after birth, but low concentrations were observed in maternal milk. On the contrary, total antioxidant status (TAS) showed a declining tendency in neonatal blood and an increasing tendency in breast milk. Markers of oxidative stress and antioxidant capacity were independent of the mode of delivery.

CONCLUSIONS

Values of oxidative stress markers in mothers and newborns immediately after birth were elevated and increased further during the first few days of neonatal life. Breast milk was the only nutritional substance with high antioxidant activity. At the same time, TBARS levels in breast milk decreased, which might indicate its protective role in reducing oxidative stress in newborns.

Effectiveness of laparoscopic surgeries in treating infertility related to endometriosis

INTRODUCTION

Endometriosis is defined as an illness caused by the presence of foci of endometrial tissue outside the uterine cavity. The illness is found in 5-10% of women at reproductive age. In the group of those suffering from endometriosis, the percentage of infertile women amounts to 50%. At higher stages of endometriosis clinical advancement, the suggested treatment is the application of assisted reproductive technology.

OBJECTIVE

The aim of the study was assessment of the effectiveness of laparoscopy in treating infertility related to endometriosis among women treated in our clinic in 2009-2012.

MATERIALS AND METHOD

The clinic is a medical centre focused on advanced minimally invasive surgical treatment, especially laparoscopic surgeries in diseases of the uterus - with a focus on laparoscopic surgeries for patients with endometriosis of the recto-vaginal area. 53 female patients treated for infertility who underwent a laparoscopic surgical procedure to remove the foci of endometriosis in 2009-2012, were analysed retrospectively. After the surgical procedure, the patients were observed over a period of 12 months, during which the frequency of pregnancies (including natural and assisted pregnancies) was assessed in relation to the stage of endometriosis advancement (rAFS).

RESULTS

In 17 out of 53 (32%) patients who underwent the surgical procedure a clinical pregnancy was diagnosed. 11 out of 53 (20.75%) women became pregnant spontaneously, 6 out of 53 (11.32%) patients became pregnant as a result of assisted reproductive technology (ART) (5 IVF and 1 IUI). The average time from the date of surgical procedure to spontaneous pregnancy amounted to 6 months.

CONCLUSIONS

Laparoscopy is a vital therapeutic method. Operative laparoscopy is an efficient method for treating infertility related to endometriosis, and the procedure seems to be the most effective particularly at stage III rAFS. The period for expectant management after a surgical procedure should last 6 months.

The prognostic significance of thrombocytosis in ovarian cancer

Ovarian cancer makes up 25-30% of all cases of cancers of the female genital tract. It has the highest mortality rate of any condition in oncological gynaecology. Early diagnosis is associated with a favourable 5-year survival prognosis. Many solid tumours have been detected with concomitant thrombocytosis. The tumour cell-induced platelet aggregation is a result of a direct integration of tumour cells with blood platelets. The aim of the present paper is an evaluation of platelet count as a prognostic parameter for ovarian cancer. Between 2000 - 2005, 349 patients with ovarian tumour (aged 12 - 88-years-old) underwent primary surgical treatment at a clinic. Ninety-seven patients with ovarian carcinomas underwent chemotherapy in the Oncology Centre. The control group comprised 252 women diagnosed with a histopathological lesion of mild intensity, whereas the cancer group constituted 97 women with a histopathologically-diagnosed malignant neoplasm. Thrombocytopaenia was assumed with a platelet count below 150G/L and thrombocythaemia at 350G/L and higher. Thrombocytosis often coincides with ascites and the cytoreduction decreases platelet count. There is a positive correlation between platelet count and tumour grading. Thrombocytosis was more frequently found in high grade tumours. There is also a positive correlation between platelet count and tumour stage according the International Federation of Gynaecology and Obstetrics (FIGO). Thrombocytosis was more frequently found in stage III and IV cancers. Patients with co-occurring thrombocytosis were found to have shorter survival periods and shorter time free from disease. This seems to give grounds for measuring platelet count before the primary surgical intervention, and suggests that the platelet count should be included in the panel of prognostic factors for patients with ovarian tumours.

[Aberrant right subclavian artery (ARSA)--a new sonographic marker for chromosomal aberrations in the second trimester--preliminary observations]

OBJECTIVES

Presentation of our own, preliminary experiences in the assessment of the right subclavian artery's (RSA) position during the second trimester scan.

MATERIAL AND METHODS

Since January 2012 our center has started to conduct the assessment of the position of the right subclavian artery in the second trimester scan. Patients who were diagnosed with an aberrant right subclavian artery (ARSA) were referred to invasive method of prenatal diagnosis. Abnormal karyotype and microdeletion 22q11 were analyzed. Detailed echocardiography was conducted in each case.

RESULTS

Between January 2012 and September 2013 we diagnosed 19 cases of ARSA. There were three cases of congenital heart defect (15.8%; 3/19) (ventricular septal defect--VSD, n=2, atrioventricular septal defect--AVSD, n=1). Two out of 17 cases showed an abnormal karyotype (11.8%; 2/17)--46,XY del(5) (q15q31) and 47,XX+18. No 22q11.2 deletions were observed. Two patients did not consent to invasive methods of prenatal diagnosis.

CONCLUSIONS

The position of the right subclavian artery (RSA) should be routinely assessed during the second trimester of ultrasound screening. The presence of ARSA increases the risk for abnormal karyotype in the fetus and therefore, all patients who are diagnosed with ARSA should be referred to the reference center.

Prenatal diagnosis of craniosynostosis (compound Saethre-Chotzen syndrome phenotype) caused by a de novo complex chromosomal rearrangement (1; 4; 7) with a microdeletion of 7p21.3-7p15.3, including TWIST1 gene--a case report

Craniosynostosis (a premature fusion of the cranial sutures) occurs with a frequency of 1 in 2100-2500 births and in over 40% cases is caused by known genetic factors--either single gene mutations or chromosomal rearrangements. Cases caused by complex chromosomal abnormalities are uncommon and likely associated with compound phenotype. Saethre-Chotzen syndrome (SCS) [#101400] is caused by TWIST1 gene haploinsufficiency. Its phenotype includes uni- or bicoronal synostosis, short stature, facial dysmorphism and variable anomalies of the hands and feet. Due to its poor sonographic manifestation a prenatal diagnosis of SCS is challenging. We report a case of a prenatally detected craniosynostosis (compound Saethre-Chotzen syndrome phenotype) caused by a de novo complex chromosomal rearrangement (1; 4; 7) with a microdeletion of 7p21.3-7p15.3, including TWIST1 gene.

[Maternal blood intrauterine transfusions in the therapy of red-cell alloimmunization performed in three difficult cases]

Maternal alloimmunization can lead to hemolytic anemia, hydrops fetalis and even fetal or neonatal death. Intrauterine treatment is possible and effective even though it is associated with some risk. We present a rare method of maternal blood intrauterine transfusions in the therapy of three difficult cases of erythroblastosis fetalis. The aim of this report was to present an alternative to volunteer donors. In severe cases, i.e. in the absence of matching blood types from the donor in the presence of multiple alloantibodies in the pregnant woman or if multiple transfusions are required, this can be the only therapeutic option. To the best of our knowledge, this has been the first publication on maternal blood donation for intrauterine transfusion in the Polish literature.
