To analyze of the relationship between selected clinical and metabolic parameters in young women with polycystic ovary syndrome (PCOS) and normal thyroid function or subclinical hypothyroidism (SCH).
A cross-sectional cohort study.
Tertiary care setting.
Women diagnosed with PCOS according to the Rotterdam criteria (n=168).
Clinical, hormonal and metabolic parameters were evaluated. SCH was defined as thyroid-stimulating hormone (TSH) levels of 4.5-10 mIU/L.
Main outcome measure:
Separately, PCOS and SCH exert adverse effects on metabolic parameters; however, in conjunction their effect is unclear. This study evaluated whether SCH in women with PCOS affects clinical, hormonal and metabolic parameters.
The mean age of the 168 women was 24±5.8 years. Mean body mass index was 33.4±8.2. Thyroid function was normal in 149 women, while 19 had SCH. Only serum LDL-c and PRL levels were significantly higher in the women with SCH (122.6±25.6 and 17.7±7.7) compared to those with normal thyroid function (105.6±33 and 14±10.3).
In young women with PCOS, SCH is associated with higher LDL-c levels, albeit with no changes in other lipid profile parameters, insulin resistance or phenotypic manifestations. This study adds to current evidence supporting an association between PCOS and SCH.
