Frequency and Correlates of Albuminuria in Adult Bangladeshi Women with Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is associated with various metabolic risks imparting a higher risk for cardiovascular diseases (CVD) in affected women. Urinary albumin excretion (UAE) is a marker of endothelial leakiness and reflects early endothelial damage; thus is used as an important cardiovascular (CV) risk marker. UAE as a CV risk marker in PCOS patients is less well established. This cross-sectional study was done in a tertiary hospital of Bangladesh from January to December 2018 and 95 consecutive adult PCOS patients were screened for UAE. Clinical and anthropometric data were collected, and oral glucose tolerance test (OGTT), fasting lipid profile, serum creatinine, urine routine examination, total testosterone, prolactin, and TSH were measured. The urine albumin-to-creatinine ratio (UACR) was measured in a random single-voided urine sample. UACR cutoff ≥30mg/g was used to define albuminuria. The mean age of the subjects was 22.5±5.0 years; 72.6% were overweight/ obese; 68.4% had abdominal obesity; 94.7% had dyslipidemia and 40% of them had metabolic syndrome. Albuminuria was observed in 21.1% of the subjects. A higher frequency of metabolic syndrome was observed in albuminuric subjects than non-albuminuric ones (45% vs. 38.7%), though the difference was not statistically significant (p=0.617). Albuminuric subjects had higher plasma glucose (PG) value at 2 hours of OGTT and a higher frequency of acne. Other clinical, biochemical and hormonal parameters were similar in the two groups. PG 2 hours after OGTT and serum triglyceride (TG) showed positive correlations and LDL cholesterol showed a negative correlation with UACR. Our study emphasizes the need for screening PCOS women for UACR which may be helpful in identifying those subjects with future high risk of CVD.
