Brief summary

The study will be carried out at the hospital of the medical school of sao paulo (HC-FMUSP) and the goal is to compare the effects of the administration of myo-inositol in relation to the effects of metformin in women with Polycystic Ovary Syndrome and insulin resistance or glucose intolerance. Menstrual cycle, hyperandrogenism, chronic inflammatory process, carbohydrate metabolism, hepatic steatosis will be evaluated. In total, 60 women in the reproductive period, with a variable age between 18 and 36 years old will be recruited and randomized in two groups: intervention- myo-inositol for 6 months, control group will use metformin also for 6 months.

Detailed description

The study will involve 60 women in the reproductive period, with a variable between 19 and 36 years old and diagnosed with polycystic ovary syndrome (PCOS), according to Rotterdam- European Society of Human Reproduction and Embryology (ESHRE) / American Society for Reproductive Medicine (ASRM) criteria defined in 2003 and revised in 2018, and insulin resistance (presence acanthosis nigricans) or glucose intolerance (fasting glycemia, glycated hemoglobin or 75g glycemic overload and blood glucose assessment after 2 hours). It is a comparative and non-inferiority study of myo-inositol in relation to metformin. They will be divided into two groups of 30 patients: Group I (control) - they will receive metformin 850 mg, orally, twice a day; Group II (experiment) - they will receive myo-inositol 2g + folic acid 200mcg, orally, twice a day.

Interventions

DRUGMyo-inositol

30 women with polycystic ovary syndrome and insulin resistance or glucose intolerance will used myo-inositol 2g + folic acid 200mcg twice daily for 6 months, having a re-evaluation every 3 months. Evaluation will be made by transvaginal ultrasound, abdominal ultrasound, inflammatory tests, hormonal tests, glycemic curve with insulin curve, lipid profile, body mass index, evaluation of abdominal and hip circumference.

DRUGMetformin

30 women with polycystic ovary syndrome and insulin resistance or glucose intolerance will used metformin 850 mg twice a day for 6 months, having a re-evaluation every 3 months. Evaluation will be made by transvaginal ultrasound, abdominal ultrasound, inflammatory tests, hormonal tests, glycemic curve with insulin curve, lipid profile, body mass index, evaluation of abdominal and hip circumference.

Design outcomes

Primary

MeasureTime frameDescription
Menstrual cycle6 monthsAnalysis of period calendar.
Change in glucose metabolismEvery 3 months for up to 6 monthsGlucose tolerance curve with insulin curve will be performed every 3 months.
Change in glycated hemoglobinEvery 3 months for up to 6 monthsGlycated hemoglobin will be performed every 3 months.
Change in ultrasound of the ovaries6 monthsTransvaginal ultrasound to assess ovarian volume (measured in cubic centimeters) will be done before and after treatment.
Change in antral follicle count6 monthsUltrasound of the ovaries will be done before and after treatment for antral follicle count (all follicles from 2 to 9 mm will be measured)
Change in body mass indexEvery 3 months for up to 6 monthsBody mass index (kg/m2) will be assessed every 3 months.
Change in Abdominal Circumference and Hip CircumferenceEvery 3 months for up to 6 monthsAbdominal circumference and hip circumference (measured in centimeters) will be assessed every 3 months.
Change in body weight in kilogramsEvery 3 months for up to 6 monthsPatients will be weighed every 3 months (measured in kilograms).

Secondary

MeasureTime frameDescription
Modified Ferriman-Gallwey Score6 monthsModified Ferriman-Gallwey Score will be performed before and after treatment and patients with a score above 7 will be considered hirsute.
Assess adherence to treatment.Every 3 months for up to 6 monthsMedication use diary will be delivered and will be reviewed every 3 months to assess adherence to treatment (good adherence will be considered use of more than 80% of the medication provided).
Hormonal dosage (FSH, LH, progesterone, estradiol)6 monthsHormonal dosage (FSH - Follicle-stimulating hormone, LH - luteinizing hormone, progesterone, estradiol) will be preformed before and after treatment.
Side effectsEvery 3 months for up to 6 monthsQuestionnaire will be carried out every 3 months for patient to describe the 3 main side effects and how much they have hindered the treatment or not.
Hepatic steatosis6 monthsInitial liver ultrasound will be done and repeated after 6 months of treatment to assess the presence or absence of hepatic steatosis and classify it as mild (grade 1), moderate (grade 2) and severe (grade 3).
Liver enzymes6 monthsLiver enzymes (aspartate aminotransferase, alanine aminotransferase,alkaline phosphatase) will be collected before and after treatment
Chronic inflammatory process6 monthsChronic inflammatory markers will be accessed by analyzing RNA messenger from cervical-vaginal cytology before and after treatment.
C-reactive protein6 monthsChronic inflammatory process will be also evaluated by serum measurement of c-reactive protein before and after treatment.
Homocysteine6 monthsSerum homocysteine dosage will be done before and after treatment to help assess a chronic inflammatory process.
Change in Lipid ProfileEvery 3 months for up to 6 monthsSerum dosage of the lipid profile (high density lipoprotein - HDL, low density lipoprotein - LDL , very low density lipoprotein - VLDL, triglycerides, total cholesterol) will be done every 3 months
