Oral Administration of DCI to Women With PCOS (PCOS)

November 15, 2011 updated by: Virginia Commonwealth University

Determination if Oral DCI Administration to Women With PCOS Increases Total DCI Content in Urine and Blood...

To determine if oral DCI administration to women with PCOS increases the total DCI content in urine and blood, and, if so, if that change is accompanied by i) an increase in DCI-IPG release in blood (as determined by bioactivity) during an oral glucose challenge and ii) an increase in whole-body insulin sensitivity.

Detailed Description

A total of 46 women will be studied. We will study 23 obese and 23 non-obese women. There will be no BMI restriction. Twenty-three women will be randomly assigned to receive DCI (experimental group) and 23 women to receive placebo (control group). The women will be studied during the equivalent of the follicular phase of the cycle, as documented by a serum progesterone concentration of 2 ng/ml.

PCOS will be defined using criteria developed at the 1990 NICHD conference on PCOS3 - i.e., all women will have oligomenorrhea (eight or fewer menstrual periods annually) and hyperandrogenemia (elevated serum total or free testosterone concentration), and secondary causes of hyperandrogenism or ovulatory dysfunction will be excluded (see below: Entrance Criteria). All women will undergo a standard oral glucose tolerance test (OGTT) to screen for diabetes mellitus,16 but impaired glucose tolerance (IGT) will not be an exclusion criteria because of the high prevalence of IGT in this population.8,17-19 We intentionally will not screen the women for the presence of insulin resistance. Women with PCOS who have disorders associated with insulin resistance - such as hypertension21-23 or dyslipidemia21-23 - will not be excluded as long as they have been on a stable dose of medication for 6 months.
