Thirty-Eight-Year Follow-Up of Two Sibling Lipoid Congenital Adrenal Hyperplasia Patients Due to Homozygous Steroidogenic Acute Regulatory (STARD1) Protein Mutation. Molecular Structure and Modeling of the STARD1 L275P Mutation.

Objective: Review the impact of StAR (STARD1) mutations on steroidogenesis and fertility in LCAH patients. Examine the endocrine mechanisms underlying the pathology of the disorder and the appropriate therapy for promoting fertility and pregnancies. Design: Published data in the literature and a detailed 38-year follow-up of two sibling LCAH patients. Molecular structure and modeling of the STARD1 L275P mutation. Setting: University hospital. Patients: Patient A (46,XY female phenotype) and patient B (46,XX female) with LCAH bearing the L275P mutation in STARD1. Interventions: Since early-age diagnosis, both patients underwent corticoid replacement therapy. Patient A received estrogen therapy at pubertal age. Clomiphene therapy was given to Patient B to induce ovulation. Pregnancies were protected with progesterone administration. Main Outcome Measures: Clinical and molecular assessment of adrenal and gonadal functions. Results: Both patients have classic manifestations of corticosteroid deficiency observed in LCAH. Time of onset and severity were different. Patient A developed into a female phenotype due to early and severe damage of Leydig cells. Patient B started a progressive pubertal development, menarche and regular non-ovulatory cycle. She was able to have successful pregnancies. Conclusions: Understanding the molecular structure and function of STARD1 in all steroidogenic tissues is the key for comprehending the heterogeneous clinical manifestations of LCAH, and the development of an appropriate strategy for the induction of ovulation and protecting pregnancies in this disease.

The Obesity-Fertility Protocol: a randomized controlled trial assessing clinical outcomes and costs of a transferable interdisciplinary lifestyle intervention, before and during pregnancy, in obese infertile women.

BACKGROUND: Obesity in infertile women increases the costs of fertility treatments, reduces their effectiveness and increases significantly the risks of many complications of pregnancy and for the newborn. Studies suggest that even a modest loss of 5-10 % of body weight can restore ovulation. However, there are gaps in knowledge regarding the benefits and cost-effectiveness of a lifestyle modification program targeting obese infertile women and integrated into the fertility clinics. This study will evaluate clinical outcomes and costs of a transferable interdisciplinary lifestyle intervention, before and during pregnancy, in obese infertile women. We hypothesize that the intervention will: 1) improve fertility, efficacy of fertility treatments, and health of mothers and their children; and 2) reduce the cost per live birth, including costs of fertility treatments and pregnancy outcomes. METHODS/DESIGN: Obese infertile women (age: 18-40 years; BMI ≥30 kg/m(2) or ≥27 kg/m(2) with polycystic ovary syndrome) will be randomised to either a lifestyle intervention followed by standard fertility treatments after 6 months if no conception has been achieved (intervention group) or standard fertility treatments only (control group). The intervention and/or follow-up will last for a maximum of 18 months or up to the end of pregnancy. Evaluation visits will be planned every 6 months where different outcome measures will be assessed. The primary outcome will be live-birth rates at 18 months. The secondary outcomes will be sub-divided into four categories: lifestyle and anthropometric, fertility, pregnancy complications, and neonatal outcomes. Outcomes and costs will be also compared to similar women seen in three fertility clinics across Canada. Qualitative data will also be collected from both professionals and obese infertile women. DISCUSSION: This study will generate new knowledge about the implementation, impacts and costs of a lifestyle management program in obese infertile women. This information will be relevant for decision-makers and health care professionals, and should be generalizable to North American fertility clinics.

Endometrioid ovarian cancer and endometriotic cells exhibit the same alteration in the expression of interleukin-1 receptor II: to a link between endometriosis and endometrioid ovarian cancer.

AIM: Endometrioid carcinoma of the ovary is the third most common type of epithelial ovarian cancer. Endometrioid tumors as well as endometriotic implants are characterized by the presence of epithelial cells, stromal cells, or a combination of booth, that resemble the endometrial cells, suggesting a possible endometrial origin of these tumors. Th1 cytokines including interleukin (IL)-1 have been reported to be involved in both endometriosis and ovarian carcinogenesis. We assessed the expression of receptors of IL-1 (IL-1RI and IL-1RII, the signal transducer and the specific inhibitor of IL-1, respectively) in cells of the most common subtypes of ovarian cancer compared to endometrial cells. MATERIAL & METHODS: IL1-Rs expression was analyzed at the levels of the protein and mRNA using immunofluorescent and real-time polymerase chain reaction methods, respectively. RESULTS: We showed that endometrioid cells exhibit a specific decrease of IL-1RII expression, whereas IL-1RI was constantly expressed in all studied cell subtypes. CONCLUSION: As already reported in endometriotic cells, endometrioid ovarian cancer cells exhibit the same alteration in the expression of IL-1RII, a key protector against tumorigenic effects of IL-1. Our findings highlight a common signature between endometrioid ovarian cancer and implants of endometriosis, which needs to be fully explored.

Expression of interleukin-1 (IL-1) ligands system in the most common endometriosis-associated ovarian cancer subtypes.

OBJECTIVES: Endometrioid carcinoma of the ovary is one of the most types of epithelial ovarian cancer associated to endometrioisis. Endometrioid tumors as well as endometriotic implants are characterized by the presence of epithelial cells, stromal cells, or a combination of booth, that resemble the endometrial cells, suggesting a possible endometrial origin of these tumors. Pro-inflammatory cytokines, including interleukin-1 (IL-1) have been reported to be involved in both endometriosis and ovarian carcinogenesis. The major objective of this study was to determine the level expression of IL-1 ligands system (IL-1alpha, IL-1beta and IL-1RA) in the most common subtypes of ovarian cancer cells compared to endometrial cells. METHODS: We used primary endometrial cells, endometrial cell line RL-952 and different subtypes of epithelial ovarian cancer cell lines including TOV-112D (endometrioid), TOV-21G (clear cell) and OV-90 (serous). Immunofluorescence and real-time PCR analysis were used respectively for detecting IL-1 ligands at the levels of cell-associated protein and mRNA. Soluble IL-1 ligands were analyzed by ELISA. RESULTS: We demonstrated that IL-1 ligands were expressed by all endometriosis-associated ovarian cancer subtypes and endometrial cells. In contrast to other cancer ovarian cells, endometrioid cells exhibit a specific decrease of cell-associated IL-1RA expression and its soluble secretion. CONCLUSION: Endometrioid ovarian cancer exhibits an alteration in the expression of IL-1RA, a key protector against tumorogenic effects of IL-1. This alteration evokes the same alteration observed in endometriotic cells in previous studies. This suggests a possible link between the endometrium, the tissue ectopic endometriosis and endometrioid ovarian cancer.

Gonadal function, first cases of pregnancy, and child delivery in a woman with lipoid congenital adrenal hyperplasia.

CONTEXT: Mutations in the steroidogenic acute regulatory protein (StAR) gene often cause lipoid congenital adrenal hyperplasia (LCAH). In this disorder an impairment of steroid synthesis leads to adrenal and gonadal insufficiencies with a particular female genital phenotype in both human karyotypes. Pregnancy in LCAH has not been yet reported. OBJECTIVE: We describe the first cases of pregnancy in a LCAH female patient bearing the L275P mutation in the StAR gene. DESIGN: We studied the gonadal function, pubertal development, and apply the appropriate hormonal therapy to support pregnancies. PATIENT: A 46,xx patient of French Canadian descent was diagnosed with LCAH at the age of 4.5 months. Substitution therapy with glucocorticoids and mineralocorticoids led to normal growth and development. Progressive pubertal development started at the age of 11 7/12 yr. Menarche occurred at 14 2/12 yr with normal regular menstruations thereafter but without ovulation. RESULTS: Clomiphene stimulation induced the first pregnancy at 25 4/12 yr of age. Spontaneous abortion occurred after 6 wk gestation. The second pregnancy (with clomiphene stimulation) was induced at the age of 26 yr. Progesterone (Prog) therapy was added at the 17th day of the cycle to protect pregnancy. Vaginal delivery of dichorionic-diamniotic twin pregnancy occurred at 30 wk gestation (two normal weight male babies). Two years later, again under clomiphene stimulation, she underwent another successful singleton pregnancy and delivered a normal weight female baby at 36 wk. The pregnancies were almost uncomplicated. CONCLUSION: Despite the dysfunctional StAR, pregnancy is possible under the proper therapeutic strategy.

Basic infertility including polycystic ovary syndrome.

Infertility in women has many possible causes and must be approached systematically. The most common cause of medically treatable infertility is the polycystic ovary syndrome (PCOS). This syndrome is common in young women and is the cause of anovulatory infertility in 70% of cases. It is therefore an important condition to screen and manage in primary care medical settings. In the past 10 years, insulin sensitization with weight loss or metformin has been shown to be a safe and effective treatment for PCOS infertility that eliminates the risk of multiple pregnancy and may reduce the risk of early pregnancy loss as compared with ovulation-inductor drugs. The authors believe metformin should be considered as first-line therapy because it has the advantage to allow for normal single ovulation, for reduced early pregnancy loss, and, most importantly, lifestyle modifications and weight loss before pregnancy. Losing weight not only improves fertility but also reduces adverse pregnancy outcomes associated with obesity.
