Drospirenone and cardiovascular risk in lean and obese polycystic ovary syndrome patients: a pilot study

OBJECTIVE

We sought to verify if an oral contraceptive (OC) containing drospirenone affects the cardiovascular risk of patients with polycystic ovary syndrome (PCOS).

STUDY DESIGN

A total of 28 women with PCOS (16 lean [group A] and 12 overweight [group B]) were assessed at baseline and after 6 months therapy with an OC. Leptin, homocysteine, endothelin-1, and flow-mediated dilatation of brachial artery were measured.

RESULTS

The brachial artery diameter and the pulsatility index, after the reactive hyperemia, did not change in group A; it improved significantly in group B after 6 months of treatment. At baseline and after therapy the plasma levels of homocysteine and endothelin-1 did not differ among the groups. Leptin was significantly lower at baseline in group A compared to group B.

CONCLUSION

The OC containing drospirenone does not seem to affect the surrogate markers of cardiovascular risk in lean patients with PCOS.

Periovulatory morphometric and vascular modifications of the clitoris in young adult and middle-aged women. A pilot study

INTRODUCTION

A decline in sexual activity has been reported as women age.

AIM

To compare, in young adult and middle-aged women, the clitoral volumetric and vascular modifications during the periovulatory phase of the menstrual cycle, and to analyze their relationship with circulating hormones, nitric oxide levels, and with questionnaires on sexuality, relationship, and depression.

METHODS

Fifteen young (18-25 years; Group I), and 16 middle-aged (35-45 years; Group II) eumenorrheic women were submitted, on day 14 of their menstrual cycle, to utero-ovarian and clitoral ultrasonographic analysis, and to color Doppler evaluation of the uterine and dorsal clitoral arteries. On the same day, hormonal parameters and plasma concentrations of nitrites/nitrates were assayed, and the two-factor Italian McCoy female questionnaire and the Beck's Depression Inventory questionnaire were administered.

MAIN OUTCOMES MEASURES

Utero-ovarian and clitoral ultrasonographic analysis, color Doppler evaluation of the uterine and dorsal clitoral arteries; evaluation of hormonal and nitrites/nitrates plasma concentrations; administration of the two-factor Italian McCoy Female Sexuality Questionnaire and the Beck's Depression Inventory questionnaire. RESULTS. The plasma levels of estradiol, testosterone, sex hormone binding globulin, and nitrites/nitrates were similar in both groups. Neither the ultrasonographic assessment of the clitoral body volume (0.82 +/- 0.24 mL vs. 0.73 +/- 0.26 mL) nor the Doppler analysis of the dorsal clitoral artery [pulsatility index (PI) = 1.35 +/- 0.31 vs. PI = 1.36 +/- 0.19] evidenced any significant differences in either Group I or Group II. The two-factor Italian McCoy Female Sexuality Questionnaire and the Beck Depression Inventory questionnaire gave the same results in Group I and Group II. The relationship between the different parameters evidenced that the NO(2-)/NO(3-) circulating levels are inversely correlated with uterine artery (r = -0.4611; P = 0.008) and dorsal clitoral artery (r = -0.331; P = 0.041) PIs. Furthermore, estradiol resulted inversely correlated with depression (r = -0.332; P = 0.045). The two sections (sexuality and partnership) of Italian McCoy Female Sexuality Questionnaire were positively correlated (r = 0.849; P < 0.0001) between each other.

CONCLUSIONS

In eumenorrheic young adult and middle-aged women, the periovulatory clitoral anatomic and vascular modifications similarly occur.

Ultrasonographic and Doppler findings of subclinical clitoral microtraumatisms in mountain bikers and horseback riders

INTRODUCTION

Repeated microtraumas in horseback riders and mountain bikers are, in males, associated with perineal and scrotal lesions. No data are reported in the females.

AIM

To report five cases of clitoral microcalcifications, diagnosed by ultrasonography, in six healthy, eumenorrheic athletes, and to verify the clinical and sexual impact of the ultrasonographic findings.

MAIN OUTCOME MEASURES

Translabial ultrasonographic evaluation of the clitoris, Doppler analysis of dorsal clitoral arteries, and the two-factor Italian McCoy Female Sexuality Questionnaire (MFSQ) METHODS: The patients were assessed with a detailed history, and were submitted, in the periovulatory phase of the cycle (day 14), to clitoral ultrasonographic analysis and color Doppler evaluation of the dorsal clitoral arteries. The women were not sexually aroused. On the same day, in a separate room--and prior the ultrasound and Doppler examinations took place--the subjects completed the two-factor Italian MFSQ.

RESULTS

All the patients were completely asymptomatic but reported a past history of intermittent perineal tenderness or discomfort. In five out of the six subjects, the ultrasonographic assessment of the clitoris evidenced a disseminated clitoral microlithiasis. Only the youngest (18 years old) biker showed a normal pattern of the clitoral structures. A normal clitoral body volume (0.68 +/- 0.21 mL) and a normal mean dorsal artery pulsatility index (PI) was found (PI = 1.75 +/- 0.32) in all the patients. The two-factor Italian MFSQ showed a mean value of 42 +/- 4 (range 37-45).

CONCLUSIONS

The chronic traumatisms may be responsible, especially in well-trained riders, for microhematomas, inflammation, and/or degenerative processes at level of the clitoral structure. Further studies should be undertaken to determine the clinical significance of the described disseminated clitoral microlithiasis.

Cardiovascular risk in normal weight, eumenorrheic, nonhirsute daughters of patients with polycystic ovary syndrome: a pilot study

OBJECTIVE

To verify whether healthy daughters with polycystic ovaries (PCO) of patients with polycystic ovary syndrome (PCOS) have an increased risk of cardiovascular disease in comparison with healthy controls.

DESIGN

Prospective observational study.

SETTING

University hospital.

PATIENT(S)

Seventeen eumenorrheic daughters with PCO of patients with PCOS (group 1) and 20 healthy volunteers (group 2) with regular ovulatory cycles.

INTERVENTION(S)

Fasting blood sampling, ultrasonographic and Doppler analyses, 24-hour ambulatory blood pressure monitoring.

MAIN OUTCOME MEASURE(S)

Medical examination; blood measurement of nitrites and nitrates, biochemical and hormonal parameters; utero-ovarian ultrasonographic analysis and color Doppler evaluation of uterine and stromal ovarian arteries; brachial artery flow-mediated vasodilatation; 24-hour ambulatory blood pressure monitoring. An oral glucose tolerance test was performed to analyze glucose, insulin, and C-peptide levels.

RESULT(S)

At Doppler analysis a significantly higher uterine and a lower ovarian artery pulsatility index was found in group 1 compared with group 2. The brachial artery diameter, after the reactive hyperemia, showed a greater vasodilatation in controls in comparison with women with PCO. The 24-hour blood pressure monitoring demonstrated that patients with PCO have significant higher 24-hour, daytime, and nighttime diastolic and mean arterial pressure values than controls. The nitrites and nitrates plasma levels were lower in group 1 compared with group 2. The glucose and insulin plasma values were higher in patients with PCO than in controls.

CONCLUSION(S)

Eumenorrheic nonhirsute daughters of patients with PCOS who have PCO appearance on ultrasound have an increased cardiovascular risk.

Endothelial function and its relationship to leptin, homocysteine, and insulin resistance in lean and overweight eumenorrheic women and PCOS patients: a pilot study

OBJECTIVE

To verify if patients with polycystic ovarian syndrome (PCOS), have an increased cardiovascular risk compared with healthy controls.

DESIGN

Prospective case-control study.

SETTING

University-based practice.

PATIENT(S)

Twenty eumenorrheic controls (ten lean [group A] and ten overweight [group B]) and 24 PCOS women (14 lean [group C] and ten overweight [group D]).

INTERVENTION(S)

Cardiovascular risk markers and hormonal parameters were assessed.

MAIN OUTCOME MEASURE(S)

Androgens, fasting glucose, insulin, leptin, fibrinogen, homocysteine, endothelin-1 and flow-mediated dilatation of the brachial artery were measured to investigate their relationship to weight and to PCOS.

RESULT(S)

The brachial artery diameter and the pulsatility index, after the reactive hyperemia, showed in group A the most intense vasodilatation compared with the other groups. Homocysteine levels did not differ among the groups. Endothelin-1 was significantly higher in group A compared with groups B and D. Leptin was significantly lower in groups A and C compared with groups B and D. Insulin resistance was higher in groups B and D. Group A had significantly higher glucose-insulin ratio compared with all of the other groups; group C had significantly higher glucose-insulin ratio only compared with group D.

CONCLUSION(S)

Weight and PCOS are two independent variables affecting the endothelial function.
