title: Influence of adrenal hyperandrogenism on the clinical and metabolic phenotype of women with polycystic ovary syndrome.
abstract: OBJECTIVE
  To study the impact of adrenal hyperandrogenism (AH; defined as DHEAS concentration >95th percentile of a healthy female control population) on cardiometabolic risk factors associated with polycystic ovary syndrome (PCOS).
  
  
  METHODS
  Cross-sectional study.
  
  
  METHODS
  Academic hospital.
  
  
  METHODS
  Two-hundred ninety-eight consecutive women with PCOS, of whom 120 were obese (body mass index [BMI] ≥30 kg/m(2)) and 178 nonobese (BMI <30 kg/m(2)).
  
  
  METHODS
  None.
  
  
  METHODS
  Comprehensive evaluation of cardiovascular risk factors, including 75-g oral glucose tolerance test, office blood pressure, lipid profile, and low-grade inflammatory markers.
  
  
  RESULTS
  Patients with AH (AH-PCOS) had higher insulin circulating levels and lower insulin sensitivity than their counterparts without AH (non-AH-PCOS). Obesity, but not AH, was the main contributor to the presence of glucose tolerance disorders. Both obesity and AH increased the prevalence of prehypertension and hypertension. AH diminished high-density lipoprotein (HDL) levels in nonobese PCOS women in parallel with a decrease in total cholesterol levels, leading to a total to HDL cholesterol ratio similar to that of nonobese non-AH-PCOS patients. Furthermore, AH blunted the deleterious effect of obesity on the total cholesterol/HDL ratio, with the ratio of obese AH-PCOS patients being similar to that of nonobese PCOS patients with or without AH.
  
  
  CONCLUSIONS
  The presence of AH in women with PCOS is associated with reduced insulin sensitivity and increased blood pressure but may have beneficial impact on the lipid profile. Obesity is the main determinant of the clustering of cardiovascular risk factors in PCOS women.
