RESUMEN

In spite of the widespread use of lifestyle modifications programs, many patients with PCOS are obese and prevalence of obesity in PCOS remains high. In this study, we present the data on the use of semaglutide, an incretin mimetic drug, in obese PCOS patients who were unresponsive to a lifestyle modification program. Twenty-seven obese patients with a diagnosis of PCOS, who did not reduce their body weight by a lifestyle modification program, were included in this study and treated by semaglutide, 0.5 mg subcutaneously once a week. After three months of treatment, an improvement in body weight with a mean decrease in body weight of 7.6 kg and a mean BMI loss of 3.1 was observed, while very few side effects were reported. Almost 80% of the studied obese PCOS patients obtained at least a 5% decrease in their body weight. Only a few patients (22%) obtained a decrease in body weight lower than 5% and were considered non-responsive to semaglutide, at least at the used doses. These patients presented a more severe obesity than responsive patients. Independently of results on body weight, and in patients who did not obtain a 5% decrease in their body weight, insulin basal values decreased, and HOMA-IR improved. Fasting blood glucose normalized in 80% of semaglutide-treated IFG PCOS women. In patients who were responsive to semaglutide (weight loss > 5%), the treatment was continued for additional three months. Weight loss slowed but continued and, at the end of the six months of therapy, the mean body weight loss was 11.5 kg and mean BMI reduced from 34.4 to 29.4. A total of 80% of responsive patients normalized menstrual cycles. In conclusion, treatment with semaglutide, at low doses, significantly reduces body weight in almost 80% of obese PCOS patients who were unresponsive to a previous lifestyle plan. It is often associated with the normalization of menstrual cycles, and these important results are obtained with very few side effects.

RESUMEN

It is well known that a subgroup of women with PCOS present an excessive adrenal androgen production, generally associated with ovarian hyperandrogenism. In the past, it has been impossible to correlate adrenal hyperandrogenism to any clinical or hormonal pattern of PCOS. However, adrenal androgens are strictly dependent on age and their blood values reduce by 40% in patients moving from their twenties to thirties. Due to this, serum DHEAS values are strongly influenced by the age distribution of studied populations. To avoid this bias, in this study we retrospectively analyzed the clinical and hormonal data of PCOS women in their twenties (age between 20 and 29 years). Data of 648 young hyperandrogenic women with PCOS were evaluated. Serum DHEAS was increased in a third (33%) of studied patients and was associated with higher values of testosterone (T) and androstenedione (A). In each phenotype, patients with high DHEAS had higher values of T and A than patients with normal DHEAS of the same phenotype. Therefore, a DHEAS increase is generally part of a generalized higher androgen production in a subgroup of PCOS patients, independently of the finding of anovulatory or ovulatory cycles or of polycystic or normal ovaries. However, our study showed some important differences between PCOS phenotypes. A lower prevalence of increased DHEAS in A phenotype PCOS patients who generally have the highest androgen levels, versus non-classic (B or C) PCOS phenotypes, was observed. It was also found that patients with A phenotype PCOS present significantly lower BMI and serum insulin than patients with normal DHEAS of the same phenotype while, in patients with the B or C phenotype, the opposite occurs. We conclude that adrenal hyperandrogenism is more common in patients with non-classic (B and C) phenotypes of PCOS and is generally part of a generalized higher production of androgens in a subgroup of PCOS patients. However, other factors may increase the adrenal androgen production and influence the clinical expression of the syndrome. More studies in large, selected for age, populations of PCOS women with different phenotypes are needed.

RESUMEN

While the Rotterdam criteria look simple and easy to follow, in clinical practice diagnosis of PCOS may be problematic because of the use of inaccurate commercial androgen assays. Progresses in ovarian ultrasound and in AMH measurement have modified the way to make the diagnosis of PCOS and an update of Rotterdam criteria may be necessary. In classic severe form of PCOS, ovarian follicle count is a very reliable diagnostic criterion but AMH measurement may also present high diagnostic specificity and sensitivity. This finding is particularly important when no clinical signs of androgen excess are present and only commercial assays for androgen measurement are available. At the contrary, in mild PCOS phenotypes, sensitivity of AMH measurement is too low whileFNPO count maintains a high diagnostic sensitivity. However, at least in ovulatory hyperandrogenic PCOS phenotype, increased AMH values in association with enlarged ovarian size permit the diagnosis of ovulatory PCOS in 85% of these patients. Treatment of PCOS women has to be directed to get fertility or in patients not seeking fertility to solve or attenuate the psychological implications of androgen excess and of irregular menses and the risk of endometrial hyperplasia. The therapeutic protocols that are used in our department are presented.

RESUMEN

OBJECTIVE: To evaluate the clinical and endocrine differences between main polycystic ovary syndrome (PCOS) phenotypes. DESIGN: To evaluate clinical and hormone parameters in a large group of consecutive women with PCOS diagnosed according Rotterdam criteria and divided according their phenotype. SETTING: University department of medicine. PATIENT(S): Three hundred eighty-two consecutive women with PCOS and 85 ovulatory controls. INTERVENTION(S): Evaluation of clinical and hormone parameters. MAIN OUTCOME MEASURE(S): Blood levels of gonadotropins, testosterone, sex-hormone-binding globulin, dehydroepiandrosterone sulfate, 17α-hydroxyprogesterone, progesterone, glucose, and insulin, and calculation of the free androgen index and insulin sensitivity. RESULT(S): The severe PCOS phenotype (hyperandrogenism, chronic anovulation, and polycystic ovaries: type I classic PCOS) was the most common phenotype in 53.9% of the patients. The phenotype of 8.9% of patients was characterized by hyperandrogenism and chronic anovulation but normal ovaries (type II classic PCOS). The two phenotypes of classic PCOS had similar clinical and endocrine characteristics, but the patients with polycystic ovaries had a higher luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratio. Ovulatory PCOS was relatively common (28.8% of PCOS patients) and presented milder clinical and endocrine alterations than the classic PCOS phenotypes. The normoandrogenic phenotype was relatively uncommon. These patients had a normal body mass index, insulin sensitivity, and free androgen index but showed increased levels of LH and LH/FSH ratio. CONCLUSION(S): Ovulatory PCOS represents the mild form of classic PCOS, but the normoandrogenic phenotype, although part of the spectrum, may represent a different disorder or have a different pathogenetic pathway.

RESUMEN

OBJECTIVE: To evaluate the role of social and cultural differences inside the same ethnic group on the ovulatory status of women with polycystic ovary syndrome (PCOS). DESIGN: To correlate social and cultural status with the phenotypic expression (body weight and ovulation) and with androgen and insulin levels of PCOS. SETTING: University department of medicine. PATIENT(S): Two hundred and forty-four consecutive PCOS women. INTERVENTION(S): All studied patients completed a simple questionnaire to indicate their mean family income and their school education. MAIN OUTCOME MEASURE(S): Ovulation was assessed by measurement of serum progesterone on day 22 of a spontaneous or induced menstrual cycle. Levels of blood testosterone, sex hormone-binding globulin, insulin, and blood glucose were evaluated. RESULT(S): In the low to medium income group, 21% of patients had ovulatory PCOS, but the prevalence of the same PCOS phenotype was 43% in patients with high income. In patients with low education, only 12% presented with ovulatory PCOS compared with 47% of the patients with high education status. Mean family income negatively correlated with body mass index, waist circumference, insulin, and insulin resistance. Serum progesterone correlated negatively with insulin and insulin resistance. CONCLUSION(S): In an ethnically homogeneous PCOS population, high socioeconomic status was associated with a higher prevalence of the ovulatory phenotype. Differences in ovulatory status between the social classes seem to be related to differences in insulin levels and fat quantity and distribution.
