About this study

Official title: Therapeutic Effect of Vitamin D3 Supplementation to Clomiphene Citrate Resistant Polycystic Ovary Syndrome Women

This study is determining the therapeutic effect of Vitamin D supplements to Pcos clomiphene resistant polycystic ovarian syndrome Women. Half of patients will receive Vitamin D with metformin while other half metformin only. Then both groups start clomiphene for 3 month

Read the detailed description

Polycystic ovary syndrome (PCOS) is considered one of the most common endocrine disorders affecting women in their reproductive age. Genetically it is thought to be involving defects in primary cellular control mechanisms resulting in expression of chronic anovulation and androgen excess. Being familial condition , some researches showed it is autosomal dominant while others thought it is complex trait with oligogenic basis.

Diagnosing poly cystic ovary syndrome is based on finding two of three criteria according to Rotterdam consensus 2003 : oligo/anovulation, clinical/ biochemical signs of hyperandrogenism, ultrasound finding of polycystic ovaries. While insulin resistance which affects 50 - 70 % of PCOS patients is considered to be the main reason for hyperandrogenic features, PCOS also leads to various health problems including metabolic disorders (obesity - Diabetes Mellitus - Cardiovascular diseases) in addition to menstrual irregularities and infertility .

In PCOS women there is polymorphism in Vitamin-D receptor (VDR) gene associated with vitamin D level in blood . This gene is isolated from the female reproductive organs . In VDR null mice; uterine hypoplasia, impaired folliculogenesis and infertility is noted . That's why it is thought to be contributing in the genomic regulation of reproduction.

Several studies have investigated the effectiveness of Vitamin D supplementation to PCOS women they found that PCOS women have hypovitaminosis D3 , with increasing evidence that vitamin D affects insulin and glucose metabolism . vitamin D intake in PCOS women may improve hormonal profiles in addition to having anti-inflammatory and anti-oxidant effects . Another study concluded that Vitamin D and calcium supplementation to PCOS women have a positive effect on BMI, follicular maturation, regularity of menses, androgen related symptoms, infertility and insulin resistance . Moreover, Vitamin D has a crucial role in ovulation induction in women with PCOS.

Vitamin D and calcium in combination with metformin have significant effect on menstrual regulation and follicular development.

Insulin sensitizers such as metformin have been extensively investigated in the management of PCOS. Metformin decreases blood glucose levels by enhancing peripheral glucose uptake, decreasing intestinal glucose absorption and suppressing hepatic glucose levels. In anovulatory women with PCOS, metformin decreases insulin levels, luteinizing hormone (LH) production and circulating androgen levels.

Clomiphene citrate is an estrogen agonist and antagonist. It works by competitively binding estrogen receptors in the thalamus and as it remains in place for an extended period of time, it depletes the body's estrogen concentration at the hypothalamic level. As the body perceives low levels of estrogen, gonadotropin-releasing hormone (GnRH) is released which in turn stimulates pituitary release of follicle stimulating hormone ( FSH) which promotes follicular growth and maturation. If pregnancy is not achieved by 3-6 cycles, other treatments should be considered.

What is being measured

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

  1. Follicle growth and maturation

    Transvaginal ultrasound will be done every 48 hours at the start from day 10 of the cycle to assess if the follicle reaches 17-19 mm

    Measured: 11days

  2. Change in Follicle growth and maturation at 3rd month

    Transvaginal ultrasound will be done every 48 hours at the start from day 10 of the cycle to assess if the follicle reaches 17-19 mm

    Measured: 11 days

  3. Change in Follicle growth and maturation at 5th month

    Transvaginal ultrasound will be done every 48 hours at the start from day 10 of the cycle to assess if the follicle reaches 17-19 mm

    Measured: 11 days

Secondary outcomes (1)
  1. Occurence of Chemical pregnancy occurence

    Positive pregnancy test

    Measured: recorded at any time point during the study whenever occurs up to 5 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Vit D, Metformin and Clomiphene in people with PCOS and Vitamin D Deficiency, run by Ain Shams University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Follicle growth and maturation (time frame: 11days). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2019.
