  • Ages 20 to 45 years
  • Women only
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Age criteria of 20-45 years: the investigators are determining the effects of ovarian suppression on adiposity and vascular in premenopausal women;
  • Premenopausal defined as normal menstrual cycle function defined as no more than 1 missed cycle in the previous year: irregular menstrual or missed menstrual cycles could indicate that women are anovulatory and/or perimenopause;
  • Not pregnant or planning to become pregnant;

About this study

The menopause transition is associated with a decrease in artery health and an increased risk for weight gain in storing fat in the stomach area which may increase the risk for heart disease. The purpose of this research is to study how the decrease in estrogen at menopause changes artery health and fat gain, and risk of disease in women as they age. The first aim in this study will determine whether short term and long term low estrogen levels in premenopausal women decreases artery function and whether this is related to an increase in fat in the stomach area. The second aim will determine whether the changes in artery health and body fat are related to changes in a pathway that breaks down an important amino acid called tryptophan. This pathway is thought to play a role in regulating the aging process. Therefore, the investigators will determine whether the decrease in artery health and the increase in body fat in the stomach region with low estrogen is related to changes in this pathway in the blood, in vascular cells and fat tissue. Because estrogen levels fluctuate in premenopausal women, the investigators will use an approach (intervention) that controls estrogen levels to address these aims. The investigators will use a medication that is typically used to treat endometriosis or uterine fibroids to lower estrogen levels and an estrogen patch to increase estrogen in some women. Some women will receive a patch that has no estrogen (called a placebo patch). The intervention period will be 20 weeks. The study will provide us with new knowledge on how low estrogen with menopause affects artery health and fat gain estrogen.

Read the detailed description

Menopause accelerates cardiovascular disease (CVD) risk due to adverse changes in risk factors (e.g., increased body fat) and vascular health, related to changes in the hormone environment. The investigators showed that measures of vascular health progressively worsen across the menopause transition, related to increased oxidative stress. The oxidative stress-mediated vascular dysfunction was related to the loss of estrogen. The loss of estrogen with menopause also causes an increase in percent body fat levels, particularly in the abdominal region. However, it is unknown if the increase in abdominal body fat worsens vascular dysfunction with the loss of estrogen. Thus Aim 1 of Project 1 will investigate the impact of increased abdominal adiposity superimposed on the direct effects of estrogen deficiency on vascular function in women. In collaboration with SCORE Projects 2 and 3, Aim 2 and an Exploratory aim will investigate the underlying causes for the increase in abdominal body fat and vascular dysfunction. There is emerging evidence that links the tryptophan-kynurenine (TRP-KYN) pathway as a regulator of vascular function, body fat and the aging process. TRP is an essential amino acid that is metabolized to KYN and various metabolites. KYN and some of its breakdown products have been associated with an increase in body fat and an impairment in vascular function. It is unknown if estrogen regulates this pathway. Thus, Aim 2 and the Exploratory aim will investigate if the TRP-KYN pathway is dysregulated with the loss of estrogen, and if this is associated with an increase in abdominal body fat and an impairment in endothelial function.

The Aims of Project 1 will be accomplished by conducting an intervention trial in premenopausal women randomized to a low estrogen condition (gonadotropin releasing hormone antagonist, GnRHant, plus a placebo patch) or a high estrogen condition (GnRHant plus an estrogen patch) to isolate the actions of estrogen. Women will wear a patch daily that will be switched out weekly. At weeks 9 and 17, women will receive 5 mg of medroxyprogesterone acetate (MPA) for 12 days to prevent endometrial hyperplasia. Outcomes will be assessed before the intervention and after 2 and 20 weeks of the intervention, except where indicated. All women will continue their intervention until testing has been completed. Initially, women interested in the study will undergo a phone or e-mail screening to assess likelihood for eligibility.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DegarelixDrug

    Also called GnRH antagonist, Ovarian suppression

    After first undergoing a pregnancy test, a clinician will administer an 80-mg subcutaneous injection of degarelix acetate (20 mg/mL; Ferring Pharmaceuticals Inc, Parsippany, NJ) to the women. A second injection will occur at 10 weeks. Compliance to the intervention will be ensured by having participants receive injections in the Clinical and Translational Research Center (CTRC), where all study visits will take place.

  • Transdermal Estradiol PatchDrug

    Treatment will be a weekly transdermal patch (0.075 mg) administered in a double-blinded manner. This estradiol dose increases serum estradiol to ~90 pg/mL. Compliance to the intervention will be monitored by having participants keep a log that tracks patch use.

  • Transdermal Placebo PatchDrug

    Treatment will be a weekly transdermal patch (placebo inactive) administered in a double-blinded manner. Compliance to the intervention will be monitored by having participants keep a log that tracks patch use.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Brachial artery flow mediated dilation (FMD)

    Ultrasound measurements of brachial artery FMD will be performed in the morning under fasted conditions, and analyzed (Vascular Analysis Tools 5.5.1) according to guidelines. Baseline FMD will be assessed during early follicular phase of menstrual cycle. Blood pressure will be measured prior to the FMD. To confirm endothelial-specific effects of the intervention, the investigators will also measure endothelium-independent dilation as brachial artery dilation to sublingual nitroglycerine (0.4 mg). All ultrasound images will be coded by number and blinded to group assignment.

    Measured: Baseline and at 2 and 20 weeks

Secondary outcomes (1)
  1. Visceral fat area (VFA)

    Participants will undergo a CT scan of the abdomen for the assessment of VFA and subcutaneous fat area (SFA). Axial CT images will be obtained through the center of the L2-L3 inter-vertebral disc space at 120 kVp (kilovoltage peak), 200-300 maS, and 10mm slice thickness. Digital images will be analyzed in a blinded manner by the University of Colorado Research Imaging Center (CU-RIC) using Interactive Data language software (ITT Visualization Solutions, Boulder, CO).

    Measured: Baseline and at 20 weeks
