AIM To investigate the connection of alpha-1 acid glycoprotein inflammatory biomarker with clinical, hormonal, and metabolic characteristics in women with polycystic ovary syndrome (PCOS) and normal cycling controls. METHODS A cross-sectional study was conducted on 235 women with PCOS and 92 normal cycling controls attended between 2008 and 2018. Alpha-1 acid glycoprotein levels were correlated with clinical, anthropometric, anthropometric-metabolic indexes, and hormones of women with PCOS and controls. Simple and multivariate stepwise linear regression, matched for age and body mass index confounding variables, was performed. RESULTS Alpha-1 acid glycoprotein levels were higher in women with PCOS (p = 0.0016). In controls, it was positively correlated with waist circumference, fat mass, body adiposity index, and lipid accumulation product, and negatively correlated with sex hormone-binding globulin (p

Aim: To compare the corticosteroidogenic enzyme activities between normal cycling non-polycystic ovary syndrome (PCOS), and normoandrogenic PCOS (NA-PCOS) and hyperandrogenic PCOS (HA-PCOS) patients. Methods: This cohort study was conducted at Julio Muller University Hospital and Tropical Institute of Reproductive Medicine and Menopause, and enrolled 114 non-PCOS women and 355 PCOS patients. The steroidogenic enzyme activities were measured using the serum steroid product/precursor molar ratio. Results: In the Δ5 pathway the 17,20 lyase activity was equally low in the NA-PCOS and HA-PCOS women compared with the non-PCOS women (P 0.05). The 3β-hydroxysteroid dehydrogenase II (3β-HSDII) activity was higher in the conversion of dehydroepiandrosterone into androstenedione in the HA-PCOS than in the NA-PCOS (P < 0.05) and the non-PCOS patients (P < 0.01). The aromatase activity was lower in the HA-PCOS than in the NA-PCOS (P < 0.05) patients and non-PCOS subjects (P < 0.01). In HA-PCOS subjects, the 17,20 lyase activity was related to insulin, estradiol, total testosterone concentrations and free androgen index in the Δ5 pathway. 3β-HSDII showed weak correlation with estradiol in the HA-PCOS group. Anthropometric parameters had little impact, if any, on the steroidogenic enzyme activities. Conclusion: The NA-PCOS and HA-PCOS patients demonstrated different enzyme activities, and the results provided new directions for future studies including PCOS patients with different phenotypes.
