Effectiveness of dual combination therapy of acarbose plus metformin and acarbose plus myo-inositol in ameliorating the metabolic and endocrinologic complications of polycystic ovary syndrome - A randomized controlled trial.

INTRODUCTION: PCOS, beyond being characterized by reproductive disturbances, is a complicated rapid expanding metabolic and endocrinologic disorder of the recent times. Nearly 70% PCOS women show resistance to insulin. AIM: The aim of the study is to determine and compare the effectiveness of acarbose plus metformin and acarbose plus myo-inositol combination therapy in alleviating the metabolic and endocrinologic complications of PCOS. MATERIALS AND METHODS: An open labelled RCT was conducted on 168 PCOS women attending the gynaecology clinic at SRM MCH & RC, Chengalpattu and the trial was registered in CTRI (No. CTRI/2022/04/041877). Group A (n = 56) received metformin 500 mg/TID alone; group B (n = 54) received (acarbose 25 mg/TID for 4 weeks then 50 mg/TID for other 20 weeks) along with metformin 500 mg/TID and group C (n = 54) received (acarbose 25 mg/TID for 4 weeks then 50 mg/TID for other 20 weeks) along with myoinositol 1000 mg/BD. All parameters were measured at baseline and at the end of 6 months. RESULTS: Significant reduction of LH, LH: FSH, TT, HOMA-IR was observed in all the groups. FSH increased only in metformin group. Increase in serum progesterone and reduction in FI, TGL, LDL were significant only in acarbose plus myo-inositol group. SHBG and HDL increased significantly only in acarbose plus metformin group. No changes in BMI, TC and VLDL were observed in any group. CONCLUSION: Therefore, decrease in FI, HOMA-IR, TGL, LDL seen in acarbose plus myo-inositol group indirectly contributes to cardio-metabolic safety in PCOS. Similarly, a significant increase in SHBG levels with acarbose plus metformin group shows correction of the excess androgen and restoration of ovulation.

Therapeutic potential of acarbose in ameliorating the metabolic and endocrinological complications of polycystic ovarian syndrome: a review.

Polycystic ovarian syndrome is a perplexed condition addressing endocrinal, cardiometabolic and gynaecological issues. It affects women of adolescent age and is drastically increasing in the Indo-Asian ethnicity over the recent years. According to Rotterdam criteria, PCOS is characterized by clinical or biochemical excess androgen and polycystic ovarian morphology; however, it has been established in the recent years that PCOS exacerbates to further serious metabolic conditions on the long term. This is a narrative literature review and not systematic review and is based on PubMed searches with relevant keywords "Polycystic ovarian syndrome AND acarbose OR metformin OR myoinositol; PCOS AND metabolic syndrome OR cardiovascular disease OR menstrual irregularity OR infertility OR chronic anovulation OR clinical hyperandrogenism" used in the title and are limited to articles published in English language with no time limits. A prominent aspect of PCOS is hyperandrogenaemia and hyperinsulinemia. About 50-70% of afflicted women have compensatory hyperinsulinemia and close to one tierce suffer from anovulation and infertility. Insulin resistance leads to metabolic complications and works with luteinizing hormone in increasing the ovarian androgen production. This excess androgen leads to clinical manifestations, irregular menstrual cycles and infertility. There isn't an entire cure, only the symptomatic clinical factors are considered rather than focusing on the underlying long-term complications. Therefore, the article focuses on a potent alpha glucosidase inhibitor, acarbose which suppresses the post meal glucose and insulin by delaying the absorption of complex carbs. It exhibits cardio-metabolic and hormonal benefits and is well tolerable in the south asian population. This review highlights the safety, effectiveness of acarbose in ameliorating the long-term complications of PCOS.

Therapeutic potential of Mucuna pruriens (Linn.) on high-fat diet-induced testicular and sperm damage in rats.

Objective: Mucuna pruriens Linn., a leguminous plant, is identified as a herbal medicine for improving fertility-related disorders in the alternative and complementary systems of medicine. The study was focused on evaluating the therapeutic potential of M. pruriens on testis and sperm parameters in a high-fat-induced hypercholesterolemia model. Materials and Methods: Male rats were divided as normal-control rats (NCR); normal-control rats + M.pruriens (200 mg/kg b.w. of ethanolic extract of M. pruriens seed) treated (NCRD); hypercholesterolemic rats (HCR) and hypercholesterolemic rats + M. pruriens (HCRD). Groups were further divided into three post-exposure periods (subgroups) of 9, 18, and 36 days, and the progressive changes in testis histology and sperm were analyzed. Results: The study showed a significant impairment in testicular histoarchitecture, depletion of antioxidant enzyme levels, increased oxidative stress and lipid peroxidation in the HCR group. The study indicated severe structural and functional damage in sperm parameters and diminished chromatin integrity in the HCR group. In the HCR rats, the follicular stimulating hormone (FSH) and luteinizing hormone (LH) and testosterone were significantly reduced. There was a significant improvement in sperm parameters and testis histology in the HCRD group. Conclusion: The study reveals the potential efficacy of M. pruriens to improve spermatogenesis, sperm parameters and hormone levels in hypercholesterolemic rats.
