Endometrial Effects of Metformin Action in Women With Polycystic Ovarian Syndrome (PCOS)

2014-08-27 03:15:50 | BioPortfolio

Summary

The investigators aim is to conduct a prospective un-blinded pilot study of premenopausal women diagnosed with Polycystic Ovarian Syndrome (PCOS), defined using criteria developed at the 1990 NICHD conference on PCOS, undergoing treatment for ovulation induction with Metformin. We propose that improving insulin sensitivity with use of Metformin in women diagnosed with PCOS has facilitatory influences on the uterine endometrium.

Description

Endometrial assessments are proposed following three month and then nine month treatment with metformin; expression of specified markers at respective time points will be compared to baseline.

Visit 1: Screening

- Signed informed consent

- Comprehensive history intake

- Physical exam: Vital signs, height, weight, waist circumferences, waist : hip ratio

- Urine pregnancy test

- Subjects provided with a 10 day supply of vaginal progesterone and EMBx will be scheduled between days 6-8 of progesterone use.

Visit 2: Baseline

- Urine pregnancy test

- Endometrium thickness will be measured via transvaginal ultrasound

- EMBx: sample of endometrial tissue will be sent for histopathology to rule out endometrial hyperplasia or cancer

- 20cc blood

- Metformin prescription and dispensing will be as per clinical care.

- Women will be advised to use barrier method of contraception (ie; condoms, contraceptive jellies or foam, sponge, diaphragm, or cervical cap) for the duration of the study.

Visits 3 and 5 (Weeks 8-10 and 30-34, respectively)

- Urine pregnancy test

- A 10 day course of vaginal progesterone to allow scheduling of EMBx's time points specified under visit 1

Visits 4 and 6 (Weeks 12 ± 1 week and 36 ± 1 week respectively)

- The procedure specified for baseline (Visit 2) will be repeated.

Medical and Biotech [MESH] Definitions

A complex disorder characterized by infertility, HIRSUTISM; OBESITY; and various menstrual disturbances such as OLIGOMENORRHEA; AMENORRHEA; ANOVULATION. Polycystic ovary syndrome is usually associated with bilateral enlarged ovaries studded with atretic follicles, not with cysts. The term, polycystic ovary, is misleading.

Specific proteins found in or on cells of progesterone target tissues that specifically combine with progesterone. The cytosol progesterone-receptor complex then associates with the nucleic acids to initiate protein synthesis. There are two kinds of progesterone receptors, A and B. Both are induced by estrogen and have short half-lives.

Steroidal compounds related to PROGESTERONE, the major mammalian progestational hormone. Progesterone congeners include important progesterone precursors in the biosynthetic pathways, metabolites, derivatives, and synthetic steroids with progestational activities.

A biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. (From Martindale, The Extra Pharmacopoeia, 30th ed, p289)

A pharmaceutical preparation of sitagliptin phosphate and metformin hydrochloride that is used in the treatment of TYPE 2 DIABETES.
