OBJECTIVE: This open-label non-randomized clinical study aimed at evaluating the effects of myo-inositol plus alpha-lactalbumin in two groups of PCOS women, treated in Mexico and Italy. Alpha-lactalbumin was used being effective in increasing myo-inositol intestinal absorption. This effect is very useful in greatly reducing the therapeutic failure of myo-inositol in some patients (inositol resistant subjects).
PATIENTS AND METHODS: The study involved 34 normal weight or overweight patients (14 in Mexico and 20 in Italy), aged 18 to 40 years, with anovulation and infertility > 1 year and insulin resistance diagnosed by HOMA-Index. Patients were administered orally with 2 g myo-inositol, 50 mg alpha-lactalbumin, and 200 µg of folic acid twice a day for 6 months. Controls were the same patients at t0 (baseline). The primary outcome was HOMA-index decrease after 3 and 6 months of treatment. Other parameters monitored were BMI, progesterone, LH, FSH, total testosterone, free testosterone, androstenedione, total cholesterol, HDL, LDL, triglycerides.
RESULTS: Recovery was general, and its relevance was higher when the starting point was further away from the normal range. The most important results were obtained with insulin, HOMA-index, LH, and androstenedione. No significant adverse effects were detected in both groups of patients.
CONCLUSIONS: This clinical trial demonstrated for the first time that myo-inositol and alpha-lactalbumin improve important parameters in PCOS patients characterized by different metabolic profiles.Free PDF Download
