The connection of alpha‐1 acid glycoprotein inflammatory marker with anthropometric, hormonal, and metabolic characteristic of women with polycystic ovary syndrome.

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 < 0.005 for all comparisons). In PCOS, it was positively correlated with testosterone, most biomarkers of central adiposity, homeostatic model assessment of insulin‐resistant, erythrocyte sedimentation rate, and negatively correlated with sex hormone‐binding globulin, high‐density lipoprotein cholesterol, glucose/insulin ratio, and lymphocytes (p < 0.055 for all comparisons). After multivariate regression in women with PCOS, alpha‐1 acid glycoprotein retained a significant positive correlation with erythrocyte sedimentation rate and C‐reactive protein. Conclusions: In PCOS, alpha‐1 acid glycoprotein is correlated with biomarkers of adiposity, carbohydrate metabolism, and total testosterone. This inflammatory marker is also correlated with erythrocyte sedimentation rate, neutrophils, and lymphocytes, frequent markers of an inflammation state. [ABSTRACT FROM AUTHOR]
