The PCOS Patients differ in Lipid Profile According to their Phenotypes.

Polycystic ovary syndrome (PCOS) affects 4-18% of women of reproductive age. The number of reports exploring the lipid profiles among PCOS patients and number of studied patients are limited. The aim of our study was to assess the lipid profile separately in lean and non-lean women with polycystic ovary syndrome divided according to hyperandrogenemia, defined as free androgen index (FAI)≥5. The second aim was to compare the lipid profiles among lean and non-lean PCOS patients with respect to hyperandrogenemia and regularity of menstruation cycles. We evaluated 232 patients from Department of Endocrinological Gynecology, Jagiellonian University Medical College in Krakow diagnosed with PCOS. The population consisted of 166 lean and 66 non-lean women. We observed higher levels of total cholesterol, high-density lipoprotein cholesterol (HDL-C) in lean patients with FAI<5 than in lean patients with FAI≥5. There were no differences in lipid profile between non-lean patients with FAI≥5 and non-lean patients with FAI<5. Among lean patients higher total cholesterol levels were observed in those with irregular menstruation cycles and FAI<5 than in patients with FAI≥5 and regular cycles. There were no differences in lipid profiles between four phenotypes among non-lean PCOS patients. CONCLUSIONS: The results of our study showed differences in lipid profile between lean PCOS patients according to their phenotype based on androgens' level. This effect was abandoned by fat tissue mass in non-lean ones. Further studies should be conducted to explore these associations.

There is no difference in the plasma cortisol level between women with body mass index (BMI) greater than or equal 25 kg/m² and polycystic ovary syndrome and the control group without polycystic ovary syndrome and BMI 25 kg/m².

A 4-8% of women of reproductive age suffer from the polycystic ovary syndrome (PCOS). The clinical and/ or biochemical hyperandrogenemia is found up to 75% of women with PCOS. It is unclear whether the hyperandogenemia in PCOS is caused directly by this disorder or by obesity. The recent studies have shown that the cortisol level in PCOS patients can be elevated, decreased or comparable to the control group. The aim of our study was to assess the cortisol plasma level in women with body mass index greater than or equal to 25 kg/ m², with and without PCOS. The study population consisted of 17 overweight women with PCOS and 44 overweight women without PCOS. There were not statistically significant differences in the body mass (group 1: 88.9 ± 17.0 kg, vs. group 2: 84.4 ± 15.2 kg; NS) nor the body mass index between both groups (group 1: 31.7 ± 5.9 kg/m², vs. group 2: 30.6 ± 5.4 kg/m²; NS). The groups did not differ in TSH, FSH, estradiol, SHBG, prolactin level at the baseline. There was no statistically significant difference between both groups in the cortisol levels at 5 a.m. and 7 a.m. Our study suggests that there is no difference in the morning and 7 p.m. cortisol level between the women with and without PCOS among the population of women with body mass index greater than or equal 25 kg/m².

Evening not morning plasma cortisol level is higher in women with polycystic ovary syndrome.

INTRODUCTION: The aim of our study was to assess the morning and evening cortisol plasma levels in women with polycystic ovary syndrome (PCOS). MATERIAL AND METHOD: 95 patients gave their informed consent to participate in the study and were divided into 2 groups. Group A consisted of 40 PCOS patients and group B consisted of 55 women without features of PCOS. Between day 5 and 8 of the menstrual cycle, morning (7 am), fasting blood samples were taken for the assessment of luteinizng hormone (LH), follicle stimulating hormone (FSH), estradiol, cortisol, prolactin, thyreotropin (TSH), testosterone and dehydroepeiandrosterone (DHEAS). Evening (5 pm) blood samples were also taken for the evaluation of plasma cortisol level RESULTS: There were no differences in mean age, body mass index (BMI), FSH, SHBG, PRL, estradiol and TSH levels between group A and group B. Mean plasma LH level was higher in group A compared to group B (10.7 ± 6.8 IU/l vs 6.6 ± 4.5 LU/l, p < 0.02). Mean plasma testosterone and DHEAS levels were also higher in PCOS patients (3.8 ± 0.6 nmol/l vs 1.63 ± 0.6 nmol/l; 427.7 ± 162.9 vs 236.6 ± 97.8 respectively, p < 0.001). Mean evening plasma cortisol level was higher in PCOS patients (11.8 ± 4.1 ug/dl vs 4.7 ± 1.3 ug/dl, p < 0.02). Mean morning plasma cortisol levels did not differ between groups. CONCLUSION: PCOS women showed the increased evening plasma cortisol level with impacted diurnal secretion rate.
