Study summary

This prospective observational study investigates the changes in serum steroid intermediates assessed by liquid chromatography-mass spectrometry (LC-MS/MS) in adolescents and young women with polycystic ovary syndrome (PCOS), before and after oral contraceptive (OCP) treatment.

Read the detailed description

The study enrolled 56 female patients aged 13-21 years with a diagnosis of PCOS according to Rotterdam criteria. At baseline, all participants underwent LC-MS/MS steroid profiling. A subgroup of 15 patients received oral contraceptive therapy based on clinical indication, independent of the study protocol. A second LC-MS/MS steroid analysis was performed at 6 months in this subgroup. The primary aim was to investigate the effect of OCP on the steroid biosynthesis profile. The study was approved by the Istanbul University Ethics Committee (Approval ID: 2019/822) and conducted between January 2020 and December 2021.

Study population

Adolescent females aged 13 to 21 years diagnosed with polycystic ovary syndrome (PCOS) according to the Rotterdam criteria. All participants were evaluated at the Istanbul Faculty of Medicine between 2020 and 2021. Baseline serum steroid profiles were analyzed using LC-MS/MS in all participants. A subset of 15 patients received oral contraceptive treatment for medical indications and had follow-up hormonal evaluations at 6 months.

Groups and cohorts

  • PCOS patients without treatment

    This cohort included adolescent patients diagnosed with polycystic ovary syndrome (PCOS) who did not receive any medical treatment during the study period. Steroid hormone levels were measured using LC-MS/MS at baseline for all participants to evaluate the endogenous steroid profile in untreated PCOS.

  • PCOS patients treated with OCP

    This cohort consisted of adolescent patients with polycystic ovary syndrome (PCOS) who were prescribed oral contraceptive pills (OCP) due to clinical indications. A total of 15 patients from the untreated PCOS group received OCP treatment and were followed for 6 months. Baseline and 6-month serum samples were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS) to evaluate changes in steroid hormone profiles after treatment.

What researchers measure

Primary outcomes

  1. Serum adrogen levels

    Change in serum androgen levels (e.g., testosterone, androstenedione, DHEAS) measured by LC-MS/MS between baseline and 6 months in the OCP-treated group.

    Time frame: 6 months

  2. serum androgen levels

    Change in serum androgen levels (e.g., testosterone, androstenedione, DHEAS) measured by LC-MS/MS between baseline and 6 months in the OCP-treated group.

    Time frame: 6 months

Secondary outcomes

  1. Change in serum steroid hormone levels after 6 months of OCP treatment in adolescents with PCOS

    Comparison of steroid hormone profiles measured by LC-MS/MS between the baseline and 6-month follow-up in adolescent PCOS patients who were treated with oral contraceptive pills (OCP). This outcome aims to assess the impact of OCP therapy on specific androgenic and progestogenic steroid metabolites.

    Time frame: Baseline and 6 months after the initiation of OCP treatment
