Filter by:Insulin-resistance plays an important role in polycystic ovary syndrome (PCOS) physiopathology. The phosphoprotein enriched in the diabetes (PED/PEA-15), a 15 kDa protein related to insulin sensitivity, is over-expressed in type 2 diabetic patients and in PCOS women, independently of obesity. The effectiveness of oral contraceptives pills (OCP) or metformin (MET) in PCOS management is still uncertain. Aim of this pilot clinical study was to compare the effects of OCPs or MET on the expression of PED/PEA-15 in association with insulin sensitivity in obese PCOS women. Outcome measures: PED/PEA-15, BMI, plasma glucose and insulin, 1/HOMA-IR, homeostasis model assessment of insulin resistance; QUICKI, quantitative insulin sensitivity check index; ISI: whole-body insulin sensitivity index. Study design: twenty obese PCOS women (age: 24.7±18 yr; BMI: 30±2.4 kg/m2) were randomized according to insulin sensitivity to receive 30 µg ethinylestradiol plus 30 mg drospirenone 21 day/month or MET 1250 mg three times daily for 6 months. Results: At baseline, age and BMI were not different in the two groups; PED/PEA-15 protein expression was higher in MET than in OCP group (p=0.011), along with higher 1/HOMA-IR (p=0.004), and lower QUICKI and ISI (p=0.003 and p<0.001, respectively). After treatment, independently of body weight, only in MET group PED/PEA-15 decreased (p=0.004), along with insulin and 1/HOMA-IR (p<0.001), and QUICKI and ISI increased (p<0.001). Insulin sensitivity indexes improvement correlated significantly with PED/PEA-15 protein expression, but not with BMI. Conclusions: PED/PEA-15 protein over-expression in obese PCOS women with IR reduced after a six month treatment with MET, while remained unchanged in the OCP group. The reduction was independent of body weight, and correlated with insulin sensitivity indexes. This effect further supported MET as a more effective therapy than OCPs for obese PCOS women with IR, also when fertility is not required.
This multicenter, randomized, open-label exploratory study will be performed in approximately 200 polycystic ovary syndrome (PCOS) but otherwise healthy females undergoing in vitro fertilization (IVF). Each study center will follow its standard practice for in vitro fertilization (IVF) within the study parameters as noted in this protocol. The study centers will use marketed products purchased from Schraft's Pharmacy for all phases of the study (down-regulation, stimulation, ovulation induction, and luteal support). Subjects will be randomly assigned to highly purified menotropin (Menopur®) or follitropin beta (Follistim Pen®) for stimulation and progesterone vaginal insert (Endometrin®) or progesterone in oil for luteal support. Subjects will return to the study center for regular scheduled clinic visits as required per in vitro fertilization (IVF) protocol at the site and at specified times during the cycle (Stimulation Day 6, Day of human chorionic gonadotropin (hCG), and first serum pregnancy test) for estradiol (E2), progesterone (P4) and human chorionic gonadotropin (hCG) labs. All subjects will be required to complete a final study visit at completion of luteal support or negative serum pregnancy test following embryo transfer.
The investigators conducted a prospective un-blinded pilot study of Vitamin D plus Calcium (Ca) supplementation in overweight (BMI > 27) premenopausal women diagnosed with Polycystic Ovarian Syndrome (PCOS), as defined by the Rotterdam Criteria, 2003, and who were deficient in vitamin D as reflected by serum 25-hydroxy (25-OH) vitamin D (serum levels < 20 ng/mL).
Flax seed oil, fish oil, and soy bean oil, are commonly recommended supplements for Polycystic Ovarian Syndrome (PCOS). These oils have different chemical structures and biological actions. It is not yet known which of these oils has the most beneficial effects in PCOS patients because they have never been compared to each other head to head. In this study the researchers hope to learn more about the effects of these oils on blood sugar and insulin levels.
Retrieval of immature oocytes from women with polycystic ovaries, their in-vitro maturation, fertilization and embryo transfer can prevent hormonal treatment that can lead to ovarian hyperstimulation. In addition, it can decrease discomfort and side-effects of routine daily administration of hormones and it can be cost-effective. Thirty healthy women with Polycystic Ovarian Syndrome aged 20-35, with BMI 18-30 kg/msq will be included in the study. Their immature oocytes will be retrieved from small follicles without any hormonal treatment. The oocytes will be fertilized post in-vitro maturation. The developed embryros will be transferred to the patients as in a routine IVF cycle.
The primary aim of the study is to assess the efficacy of letrozole as an ovulation induction agent and to test the hypothesis that letrozole will generate better pregnancy rates with fewer multiple pregnancies and higher live birth rate than the current standard agent, clomifene citrate in anovular infertile women with polycystic ovarian syndrome.
