About this study

Official title: Comparison of Cavitation Ultrasound, Metformin or the Combination of Both in Obese Women With Polycystic Ovary Syndrome

The aim of the current work was to compare the efficacy of cavitation ultrasound, metformin or combination of both in obese women with polycystic ovary syndrome (PCOS) regarding clinical pregnancy rate, ovulation rate, insulin resistance, serum testosterone level, lipid profile.

Read the detailed description

Polycystic ovary syndrome (PCOS) affects 5 to 10% of women of childbearing age and is the most common cause of anovulatory infertility. Common clinical manifestations include menstrual irregularities and signs of androgen excess such as hirsutism, acne, and alopecia. Metformin, a biguanide, is the most widely used drug for the treatment of type 2 diabetes worldwide. Its primary action is to inhibit hepatic glucose production, but it also increases the sensitivity of peripheral tissues to insulin. The increase in insulin sensitivity, which contributes to the efficacy of metformin in the treatment of diabetes, has also been shown in non diabetic women with the polycystic ovary syndrome.In women with PCOS, long-term treatment with metformin may increase ovulation, improve menstrual cyclicity, and reduce serum androgen levels; the use of metformin may also improve hirsutism. If published data on the effects of metformin in the prevention of diabetes can be extrapolated to women with the PCOS, then the drug may actually retard progression to glucose intolerance in affected women, as reported in a small, retrospective study. Ultrasonic vibrations spread in the form of a wave in medium such as a liquid or a solid. When the particles of an elastic medium are under ultrasonic vibration, they act continuously in only one direction. The lipolytic range of ultrasounds is 30-70 Kilohertz (KHz), and the best effects are obtained in a range between30-35 KHz. The depth of the treatment in the tissues is generally2-3 cm, to avoid muscles involvement. Biological effects of ultrasounds on adipocytes are: micro-mechanical, thermal, micro-streaming and cavitation. Cavitation ultrasound means that ultrasounds produce an alternation of decompression and compression waves in a fluid media which progressively increase the tension of the adipocyte until it implodes and frees the emulsified fat. The aim of the current work was to compare the efficacy of cavitation ultrasound, metformin or combination of both in obese women with polycystic ovary syndrome (PCOS) regarding clinical pregnancy rate, ovulation rate, insulin resistance, serum testosterone level, lipid profile.

What participants receive

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

  • Cavitation USDevice

    Also called Cavi SMART

    The areas with localized fat are treated 2 times per week for 3 months using Aesthetic cavitation via ultrasonic cavitation machine (Cavi SMART, South Korea, supplied with one piece cavitation probe of 40 KHz, 3-6 watt(W)/cm^2 adjustable, 60W with 20cm^2 active surface).

  • MetforminDrug

    Also called Glucophage, Bristol-Myers Squibb, New York, USA

    Metformin hydrochloride (Glucophage 500 mg/tablet, Bristol-Myers Squibb, New York, USA). Medication is initiated in a step-up fashion every 5 days, from one tablet per day to three. This dose is maintained as tolerated throughout the 3 months of the study.

  • Cavitation US + MetforminOther

    Also called Glucophage + Cavi SMART

    Combination of both Cavitation US + Metformin. the treatment duration lasts 3 months

What is being measured

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

  1. Clinical Pregnancy Rate

    Measured: 9 months

Secondary outcomes (4)
  1. Ovulation Rate as Determined by Ultrasonographic Folliculometry and Luteal Serum Progesterone Assay.

    The Number of participants who had evidence of successful ovulation during the 3 months. Ovulation was diagnosed based on ultrasonographic folliculometry and/or luteal serum progesterone assay.Every month, folliculometry was done to count the number of antral follicles (AFC), follow follicular growth, measure dominant follicle diameter and detect occurrence of ovulation. a mid-luteal serum progesterone assay was done to confirm ovulation.

    Ultrasound was performed serially till reaching preovulatory follicle(s of around 20 mm in diameter that then rupture to show a collapsed follicle in the same location with internal echoes consistent with its transformation to a corpus luteum. Progesterone assay was done using immulite 2000 apparatus chemiluminescent immunometric assay. Mid-luteal phase progesterone above 6 ng/mL was considered indicative of normal corpus. luteum function.

    Measured: 3 months

  2. Change in Insulin Resistance

    Change in Fasting insulin concentration

    Measured: Baseline and 3 months

  3. Change in Serum Free Testosterone Level

    Change in serum free testosterone levels

    Measured: Baseline and 3 months

  4. Change in Lipid Profile

    Change in LDL levels was taken as the indicator of change in lipid profile

    Measured: Baseline and 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cavitation US, Metformin and Cavitation US + Metformin in people with PCOS, 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 1 inclusion and 3 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 7 Apr 2017. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Feb 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Clinical Pregnancy Rate (time frame: 9 months). 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 7 Apr 2017.
