NCT05410834

Brief Summary

PCOS-RCE is an observational, cross-sectional, two-arm study that is aimed at determining if an established diagnosis of polycystic ovarian syndrome (PCOS) influences the number of blood vessel-forming stem cells in the bloodstream. Circulating progenitor cells will be enumerated and the distribution patterns of these cell types will be assessed to determine if these parameters differ between individuals with PCOS and individuals without PCOS. Specifically, this study will evaluate if differential regenerative cell exhaustion (RCE) may account, at least in part, for the differences in cardiovascular risk reported between individuals with a diagnosis of PCOS and those without.

Study Population

Participants will be identified from primary care clinics in the Greater Toronto Area using paper-based and electronic medical records.

You may qualify if:

  • Capable and willing to provide informed consent
  • Females aged 30 and above
  • Must meet criteria for one of the following two groups:
  • Documented diagnosis of PCOS OR
  • Normal and regular menstrual cycles with no known diagnosis of PCOS

You may not qualify if:

  • Menopause, as defined by 12 months of amenorrhea
  • Known causes of irregular menstrual bleeding caused by conditions other than PCOS
  • Known secondary causes of ovulatory dysfunction and/or hyperandrogenism
  • Current pregnancy, active lactation, or less than 6 months postpartum
  • Ongoing treatment with ovulation-inducing medication
  • History of hysterectomy and/or bilateral oophorectomy
  • Severe congestive heart failure (as defined by New York Heart Association - class IV)
  • Any life-threatening disease expected to result in death within the next 2 years
  • Any malignancy not considered cured. A subject is considered cured if there has been no evidence of cancer recurrence for the 5 years prior to screening.
  • Known severe liver disease
  • Known acquired immunodeficiency syndrome such as HIV
  • Current treatment with systemic or oral corticosteroid therapy or other immunosuppressive agents
  • Known autoimmune disorder (exception: type 1 diabetes)
  • Active infectious disease requiring antibiotic or anti-viral agents
