Effect of orlistat or metformin in overweight and obese polycystic ovary syndrome patients with insulin resistance.
The aim of this study was to evaluate the effect of orlistat or metformin combined with Diane-35 on anthropometric, hormonal and metabolic parameters in overweight and obese polycystic ovary syndrome (PCOS) patients with insulin resistance (fasting insulin > 10 mIU/L). A total of 240 PCOS women were randomly allocated to orlistat plus Diane-35(OD group), metformin plus Diane-35(MD group), orlistat plus metformin plus Diane-35(OMD group) or Diane-35 (D group). Body weight, BMI, waist and hip circumference, blood pressure, endocrine profile, lipid profile and insulin resistance were assessed at baseline and after 3 months. ⋯ Side effects were less with orlistat than metformin. This study demonstrated that orlistat is more effective in reducing weight and lipid profile than metformin. Besides, orlistat has mild side-effects and is better tolerated compared with metformin.

Does myo-inositol oxygenase, the only enzyme to catalyze myo-inositol in vivo, play a role in the etiology of polycystic ovarian syndrome?
In polycystic ovary syndrome (PCOS), myo-inositol (MI) supplements have shown many beneficial effects. In this study, therefore, we aimed to investigate the serum level of myo-inositol oxygenase (MIOX), which is the only enzyme catalyzing MI in vivo, in patients with PCOS. Serum MIOX enzyme levels and other laboratory parameters were compared between sixty patients, who were diagnosed with PCOS for the first time, and sixty healthy individuals at similar age and sex. ⋯ Although the ratio of LH/FSH was higher in the patient group, it was not statistically significant. Our results suggest that serum MIOX levels do not change in PCOS. It was, therefore, concluded that MI deficiency observed in PCOS was not related to the level of MIOX enzyme which cleaves MI.
