Introduction: Increased prevalence of functional hyperandrogenism/polycystic ovary syndrome (PCOS) has been previously described in type 1 diabetes (T1DM) patients. However, the reported prevalence rates vary depending on different diagnostic criteria. Our study aim was to determine the prevalence of PCOS and hyperandrogenic traits in premeopausal women with T1DM.

Methods: A cross-sectional study was conducted at a diabetes outpatient clinic in a tertiary Hospital from Madrid, Spain. We recruited consecutive premenopausal woman with T1DM, and menarche at least 2 years before the study. For this preliminary report, we included 40 patients. History data collection, physical exam, a complete hormonal analysis in follicular phase (including d4-androstenedione, DHEA-S, total testosterone, SHBG, 17-OH-progesterone, FSH, LH, prolactin, and TSH), and ovarian ultrasound were performed.

Results: Mean age of patients was of 28 ± 8 yr; mean duration of T1DM was of 13 ± 8 yr-old. Twenty-seven patients were on multiple daily insulin therapy, while 13 of them were on continuous subcutaneous insulin infusion. Mean BMI was of 23.8 ± 3.7 Kg/m2. Mean daily insulin dose was 0.64 ± 0.2 U/kg and mean A1C was 7.5 ± 1.8%. PCOS was diagnosed in 7 patients resulting in a 18% (95% CI: 8; 32) prevalence of PCOS according to NIH-Rotterdam, and in 6 patients resulting in a 15% (95% CI: 7; 29) prevalence of PCOS according to AES-PCOS criteria. Three patients [7% (95% CI: 3; 20)] had isolated polycystic ovarian morphology (PCOM), and 7 patients [18% (95% CI: 8; 32)] presented with oligo-amenorrhea (ovulatory dysfunction-WHO class 2).

Conclusion: Our preliminary data show a significant increase in prevalence of PCOS in premenopausal women with T1DM with respect to the general population.
