Myo-Inositol Alone Versus Myo-Inositol Plus Alpha-Lactalbumin in Women With Polycystic Ovary Syndrome (MIALA-PCOS)

5 de junho de 2026 atualizado por: Sara Reza, Quaid-e-Azam Medical College

Comparison of Efficacy of Myo-Inositol Alone With Myo-Inositol Plus Alpha-Lactalbumin on Reproductive and Metabolic Parameters in Polycystic Ovarian Syndrome

Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting reproductive-aged women and is associated with menstrual irregularities, infertility, hyperandrogenism, obesity, and insulin resistance. Myo-inositol is commonly used as an insulin-sensitizing agent to improve reproductive and metabolic outcomes in women with PCOS. Alpha-lactalbumin may enhance the intestinal absorption and bioavailability of myo-inositol and potentially improve treatment response.

This randomized controlled trial aims to compare the efficacy of myo-inositol alone versus myo-inositol plus alpha-lactalbumin in women with PCOS. Eighty-two eligible women will be randomized to receive either myo-inositol alone or myo-inositol combined with alpha-lactalbumin for 12 weeks. The study will evaluate reproductive outcomes including spontaneous conception, menstrual regularity, hirsutism, and hormonal parameters, as well as metabolic outcomes including body mass index and insulin resistance.

Descrição detalhada

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age and is characterized by ovulatory dysfunction, hyperandrogenism, and polycystic ovarian morphology. Insulin resistance plays a central role in the pathophysiology of PCOS and contributes to reproductive and metabolic abnormalities. Consequently, insulin-sensitizing therapies are increasingly used to improve clinical outcomes.

Myo-inositol is an insulin-sensitizing agent that has demonstrated beneficial effects on ovulation, menstrual regularity, endocrine function, and metabolic parameters in women with PCOS. However, some patients demonstrate a suboptimal response to myo-inositol alone. Alpha-lactalbumin, a whey protein fraction, has been reported to enhance intestinal absorption and bioavailability of myo-inositol, potentially leading to improved therapeutic outcomes.

This study is a prospective randomized controlled trial conducted at the Department of Obstetrics and Gynecology, Sadiq Abbasi Hospital, Quaid-e-Azam Medical College, Bahawalpur, Pakistan. A total of 82 women aged 18 to 35 years diagnosed with PCOS according to the Rotterdam criteria will be enrolled and randomized in a 1:1 ratio into two treatment groups.

Participants in Group A will receive myo-inositol 2 g orally twice daily with folic acid supplementation. Participants in Group B will receive myo-inositol 2 g plus alpha-lactalbumin 50 mg orally twice daily with folic acid supplementation. Both groups will receive standardized lifestyle and dietary counseling. The treatment duration will be 12 weeks.

The primary outcomes will be spontaneous conception and achievement of menstrual regularity at 12 weeks. Secondary outcomes will include changes in modified Ferriman-Gallwey score, serum luteinizing hormone levels, LH/FSH ratio, body mass index, fasting glucose, fasting insulin, and homeostatic model assessment of insulin resistance (HOMA-IR). Treatment adherence and adverse events will also be assessed.

The study aims to generate local evidence regarding the comparative effectiveness of myo-inositol alone versus myo-inositol combined with alpha-lactalbumin in improving reproductive and metabolic outcomes among women with PCOS.
