RESUMO

PURPOSE: whole body scan (WBS) performed following diagnostic or therapeutic administration of I-131 is useful in patients with differentiated thyroid carcinoma. However, it can be falsely positive in various circumstances. We aimed to report a series of pitfalls in a clinical perspective. METHODS: A search in the database PubMed utilizing the following terms: "false radioiodine uptake" and "false positive iodine 131 scan" has been made in January 2023. Among the 346 studies screened, 230 were included in this review, with a total of 370 cases collected. Physiological uptakes were excluded. For each patient, sex, age, dose of I-131 administered, region and specific organ of uptake and cause of false uptake were evaluated. RESULTS: 370 cases of false radioiodine uptake were reported, 19.1% in the head-neck region, 34.2% in the chest, 14.8% in the abdomen, 20.8% in the pelvis, and 11.1% in the soft tissues and skeletal system. The origin of false radioiodine uptake was referred to non-tumoral diseases in 205/370 cases (55.1%), benign tumors in 108/370 cases (29.5%), malignant tumors in 25/370 cases (6.7%), and other causes in 32/370 cases (8.7%). CONCLUSIONS: WBS is useful in the follow-up of patients with differentiated thyroid carcinoma, however it can be falsely positive in various circumstances. For this reason, it is critically important to correlate the scintigraphic result with patient's medical history, serum thyroglobulin levels, additional imaging studies and cytologic and/or histologic result.

RESUMO

BACKGROUND: Polycystic ovary syndrome (PCOS) is the most prevalent, chronic endocrine-metabolic disorder of adolescents and young women (AYAs), affecting 5-10% of AYAs worldwide. There is no approved pharmacological therapy for PCOS. Standard off-label treatment with oral contraceptives (OCs) reverts neither the underlying pathophysiology nor the associated co-morbidities. Pilot studies have generated new insights into the pathogenesis of PCOS, leading to the development of a new treatment consisting of a fixed, low-dose combination of two so-called insulin sensitisers [pioglitazone (PIO), metformin (MET)] and one mixed anti-androgen and anti-mineralocorticoid also acting as an activator of brown adipose tissue [spironolactone (SPI)], within a single tablet (SPIOMET). The present trial will evaluate the efficacy, tolerability and safety of SPIOMET, on top of lifestyle measures, for the treatment of PCOS in AYAs. METHODS: In this multicentre, randomised, double-blind, placebo-controlled, four-arm, parallel-group, phase II clinical trial, AYAs with PCOS will be recruited from 7 clinical centres across Europe. Intention is to randomise a total of 364 eligible patients into four arms (1:1:1:1): Placebo, PIO, SPI + PIO (SPIO) and SPI + PIO + MET (SPIOMET). Active treatment over 12 months will consist of lifestyle guidance plus the ingestion of one tablet daily (at dinner time); post-treatment follow-up will span 6 months. Primary endpoint is on- and post-treatment ovulation rate. Secondary endpoints are clinical features (hirsutism, menstrual regularity); endocrine-metabolic variables (androgens, lipids, insulin, inflammatory markers); epigenetic markers; imaging data (carotid intima-media thickness, body composition, abdominal fat partitioning, hepatic fat); safety profile; adherence, tolerability and acceptability of the medication; and quality of life in the study participants. Superiority (in this order) of SPIOMET, SPIO and PIO will be tested over placebo, and if present, subsequently the superiority of SPIOMET versus PIO, and if still present, finally versus SPIO. DISCUSSION: The present study will be the first to evaluate-in a randomised, double-blind, placebo-controlled way-the efficacy, tolerability and safety of SPIOMET treatment for early PCOS, on top of a lifestyle intervention.

RESUMO

Background and objective: Severe metabolic complications generally manifest at an early age in Berardinelli - Seip congenital lipodystrophy (BSCL) and their management is especially challenging. Nutritional intervention with low lipid diets is considered by experts to be fundamental in treating the disease when associated with medical therapy, however little is known about the beneficial effects of dietary interventions alone. Aim: To underline the importance of a well-structured low-fat diet in BSCL patients. Methods and results: A BSCL male patient strictly followed a hypocaloric hypolipemic diet (60% carbohydrates, 22% fats and 18% proteins) since clinical diagnosis at the age of one year. Interestingly, pharmacological interventions were not required at any point during the follow-up. Aged 16 years the patient was referred to our center. Biochemistry, hormonal evaluation, 75 mg oral glucose tolerance test, cardiac evaluation and abdominal ultrasound were performed, revealing no abnormalities. Genetic analysis and leptin dosage were carried out, confirming the diagnosis of BSCL type 1 (homozygosity for c.493-1G>C pathogenic variant in AGPAT2 gene) and showing undetectable circulating levels of leptin (< 0.2 mcg/L). Diet therapy alone was therefore maintained, scheduling follow-up visits every six months, with acceptable disease control ever since. Conclusions: This report proves how a low-fat diet is of great help in the management of BSCL and its complications. In addition, a specific hypolipemic diet could be used alone as an effective treatment in selected cases with high compliance and, probably, a milder phenotype.

RESUMO

Polycystic ovary syndrome (PCOS) is extremely heterogeneous in terms of clinical manifestations. The variability of the syndrome's phenotype is derived from the genetic and molecular heterogeneity, with a great deal of environmental factors that may have long-term health consequences, such as metabolic and cardiovascular (CV) diseases. There is no doubt that women with PCOS suffer from metabolic complications more than their age-matched counterparts in the general population and at an earlier age. Obesity, low steroid hormone-binding globulin (SHBG), hyperandrogenemia, insulin resistance, and compensatory hyperinsulinemia are biomediators and early predictors of metabolic complications in PCOS. Doubts remain about the real risk of CV diseases in PCOS and the molecular mechanisms at the basis of CV complications. Based on that assumption, this review will present the available evidence on the potential implications of some biomediators, in particular, hyperandrogenism, estrogen-progesterone imbalance, insulin resistance, and low SHBG, in the processes leading to CV disease in PCOS, with the final aim to propose a more accurate CV risk assessment.

RESUMO

BACKGROUND: Testicular adrenal rest tumors (TARTs) are benign neoplasms affecting patients with congenital adrenal hyperplasia (CAH). The prevalence of TART in adult patients with CAH is not well known. Ultrasonography (US) is the main tool for diagnosing TART and the role of contrast-enhanced US (CEUS) is never investigated. The aim of this study was to evaluate the TART prevalence in adults with CAH, by stratifying patients according to disease phenotype and assessing the diagnostic performance of US, color Doppler (CD) US and CEUS. METHODS: Male patients >16 years old with certain diagnosis of CAH who underwent US for TARTs, between December 2015 and September 2019 were prospectively enrolled. The control group included patients without CAH affected by testicular lesions at US other than TARTs. RESULTS: TARTs were identified in 16 of 52 patients (31%), of whom 15 (93.8%) displayed the salt-wasting (SW) form (P<0.001). The prevalence of TARTs in patients with the SW form was 54%. One patient with the non-classic (NC) form (6%) showed TART (likely the first documented case). The mean age of patients upon detection of TARTs was significantly younger compared with the control group (P<0.001); moreover, TARTs were bilateral in 15/16 patients (93.8%; P<0.001) and the largest lesion was more frequent in the medium third of testis in the TART group (87.5%), statistically different from the control group (P=0.013). CONCLUSIONS: TARTs almost exclusively affected patients with the SW form of CAH. Age at diagnosis and bilateralism are useful factors for achieving a correct diagnosis of TARTs in CAH adult patients.

RESUMO

OBJECTIVE: To understand whether polycystic ovarian morphology (PCOM) represents a transient phase, and whether an increased stroma could help to characterize the phenotype of the ovary in adolescence. METHODS: Cross-sectional population-based study on high-school students in Cagliari, Italy. The study population consisted of 257 normocyclic non-hyperandrogenic girls selected from a sample of 600 healthy volunteers recruited from 2012 to 2016. Clinical examination, medical history, blood sampling, and pelvic ultrasound (US) were performed. Postmenarchal years and body mass index (BMI) were estimated. Follicle-stimulating hormone (FSH), luteinizing hormone (LH), 17ß estradiol (E2), total testosterone (tT), delta-4-androstenedione (A), and 17-hydroxyprogesterone (17-OHP) were measured. Ovarian volume, follicular number per section (FNPS), and S/A ratio were measured by pelvic US. RESULTS: Following the Rotterdam guidelines for US PCOS diagnosis and setting the normal S/A ratio at ≤0.3, subjects were categorized into 3 groups: (1) normal ovarian morphology (NOM; n = 154, 60%); (2) polycystic ovarian morphology (PCOM) with normal S/A ratio (PCOM-NS; n = 70, 27%); and (3) PCOM with increased S/A ratio (PCOM-IS; n = 33, 13%). The NOM group had more postmenarchal years and a lower LH than both the PCOM groups, and lower A and tT than the PCOM-IS group. The PCOM-NS group had fewer postmenarchal years and lower A than the PCOM-IS group. Interestingly, unlike NOM and PCOM-NS, the prevalence of PCOM-IS remained constant among the 3 phases of postmenarchal age (10% vs 16% vs 15%, P = not significant). CONCLUSION: This study demonstrates that PCOM can be a transient condition, whereas a high S/A ratio is a stable US alteration present from early postmenarchal years.

RESUMO

OBJECTIVE: Research into cardiovascular disease (CV) prevention has demonstrated a variety of ultrasound (US) markers predicting risk in the general population but which have been scarcely used for polycystic ovary syndrome (PCOS). Obesity is a major factor contributing to CV disease in the general population, and it is highly prevalent in PCOS. However, it is still unclear how much risk is attributable to hyperandrogenism. This study evaluates the most promising US CV risk markers in PCOS and compares them between different PCOS phenotypes and BMI values. DESIGN: Women fulfilling the Rotterdam criteria for PCOS were recruited from our outpatient clinic for this cross-sectional study. METHODS: Participants (n = 102) aged 38.9 ± 7.4 years were stratified into the four PCOS phenotypes and the three BMI classes (normal-weight, overweight, obese). They were assessed for clinical and biochemical parameters together with the following US markers: coronary intima-media thickness (cIMT), flow-mediated vascular dilation (FMD), nitroglycerine-induced dilation (NTG), and epicardial fat thickness (EFT). RESULTS: There was no statistical difference among the four phenotypes in terms of cIMT, FMD, NTG or EFT, however all the US parameters except NTG showed significant differences among the three BMI classes. Adjusting for confounding factors in multiple regression analyses, EFT retained the greatest direct correlation with BMI and cIMT remained directly correlated but to a lesser degree. CONCLUSIONS: This study showed that obesity rather than the hyperandrogenic phenotype negatively impacts precocious US CV risk markers in PCOS. In addition, EFT showed the strongest association with BMI, highlighting its potential for estimating CV risk in PCOS.

RESUMO

Polycystic ovary syndrome (PCOS) is a very common endocrine and metabolic disorder with the involvement of both genetic and environmental factors. Although much has been clarified on its pathogenesis, diagnosis, clinical manifestations, and therapy, there are still areas of uncertainty. To address fundamental concepts, novel aspects and hypotheses, and future perspectives, including the possible additional benefits of treatment with nutraceuticals, an expert consensus panel formed by endocrinologists and gynecologists was established. After an independent review of the literature, the panel convened electronically on February 3, 2020, and six resolutions were created, debated, and agreed upon discussion, and finally approved in their final form in a consensus livestream meeting held on April 15. The summary of the resolutions are: (1) PCOS is a well-established medical condition that negatively affects reproduction, general health, sexual health, and quality of life; (2) the symptoms and signs of PCOS appear early in life especially in female newborns from PCOS carriers; (3) women with PCOS have significantly increased risk of pregnancy-related complications including gestational diabetes mellitus; (4) a male PCOS equivalent exists, and it may impact on metabolic health and probably on reproduction; (5) the evidence supports that medical therapy for PCOS is effective, rational, and evidence-based; (6) the evidence supports a major research initiative to explore possible benefits of nutraceutical therapy for PCOS. The proposed resolutions may be regarded as points of agreement based on the current scientific evidence available.

RESUMO

CONTEXT: Chronic glucocorticoids excess leads to morphological and functional cardiac alterations, a substrate for arrhythmias. Autonomous cortisol secretion (ACS) in adrenal incidentalomas is a model of chronic endogenous hypercortisolism. OBJECTIVE: To investigate prevalence and incidence of atrial fibrillation (AF) in a large cohort of patients with ACS. DESIGN: Retrospective study. SETTING: University hospital. PATIENTS: Patients evaluated between 1990 and 2018 for adrenal incidentalomas (n = 632), without pheochromocytoma, primary aldosteronism, Cushing syndrome, congenital adrenal hyperplasia, and adrenal malignancy. Cortisol after 1-mg dexamethasone suppression test < or > 50 nmol/L defined nonsecreting tumors (NST) (n = 420) and ACS (n = 212), respectively. INTERVENTION: Assessment of AF at baseline (n = 632) and during a median follow-up of 7.7 years retrospectively (NST, n = 249; ACS, n = 108). Comparison with general population. MAIN OUTCOME MEASURE: Prevalence and incidence of AF. RESULTS: AF prevalence was higher in patients with ACS (8.5%) than NST (3.1%, P = 0.003) and the general population (1.7%; P < 0.001 vs ACS, P = 0.034 vs NST). The age-adjusted rate ratio to the general population was 1.0 for NST and 2.6 for ACS. AF was associated with ACS (odds ratio, 2.40; 95% confidence interval [CI], 1.07-5.39; P = 0.035). The proportion of patients with AF at last evaluation was higher in ACS (20.0%) than NST (11.9%; P = 0.026). ACS showed a higher risk of incident AF than NST (hazard ratio, 2.95; 95% CI, 1.27-6.86; P = 0.012), which was associated with post-dexamethasone cortisol (hazard ratio, 1.15; 95% CI, 1.07-1.24; P < 0.001), independently of known contributing factors. CONCLUSIONS: Patients with adrenal incidentalomas and ACS are at risk of AF. Electrocardiogram monitoring may be recommended during follow-up.

RESUMO

Measuring some sex and precursor steroids is still challenging even by liquid chromatography - tandem mass spectrometry (LC-MS/MS), and few normal values are available. We developed a LC-MS/MS method for estradiol, estrone, dihydrotestosterone and 17-hydroxypregnenolone measurement, compared it with direct immunoassays, and generated sex, age, menopausal and menstrual status specific reference intervals. Liquid-liquid extraction was optimized on 300 µL serum spiked with isotopic internal standards. A 2D-LC system allowed on-line purification and separation in 11 min run. Electrospray ionization was enhanced by ammonium fluoride. MS-detection was obtained by multiple reaction monitoring. Direct ECLIA for estradiol (n = 80) and RIA for estrone (n = 41) were compared with LC-MS/MS. Reference values were estimated in healthy, lean women in reproductive age (n = 118), menopausal women (n = 33) and men (n = 159). The assay showed satisfying imprecision, trueness, recovery and selectivity. Adequate functional sensitivity was achieved for measuring estrone (18.1 pmol/L) and 17-hydroxypregnenolone (117 pmol/L) in all subjects, and estradiol (35.9 pmol/L) and dihydrotestosterone (134 pmol/L) in women in reproductive age and men, but not in menopausal women. Compared with LC-MS/MS, immunoassays showed good agreement for estradiol but severe disagreement for estrone. Estrogens exhibited sex, menopausal and menstrual variations. Dihydrotestosterone and 17-hydroxypregnenolone depended on sex and menopause, the latter also declining with age in men. Strictly defined reference intervals in the adult female and male population were generated for challenging steroids such as estrogens, dihydrotestosterone and 17-hydroxypregnenolone by a novel LC-MS/MS method. Our achievement can be used to deepen the comprehension of several endocrine diseases.

RESUMO

Obesity is associated with infertility in women through multiple and complex mechanisms. Briefly, the adipose tissue through the production of many factors, such as leptin, free fatty acids (FFA), and cytokines may affect both ovarian and endometrium functions, with a final alteration in oocyte maturation and endometrial epithelium receptivity. In addition, through the development of peripheral insulin resistance obesity produces a condition of functional hyperandrogenism and hyperestrogenism that contribute to produce anovulation and to reduce endometrial receptivity and, therefore participate to cause infertility. Weight loss is able to restore fertility in most cases, but there are no practical indications to guide the clinician to choice the best method among increased physical activity, diet, drugs, and bariatric surgery.

RESUMO

CONTEXT: Steroid profiling by mass spectrometry has shown implications for diagnosis and subtyping of adrenal tumors. OBJECTIVES: To investigate steroid profiles and their cardiovascular correlates in a large cohort of patients with nonsecreting (NS) adrenal incidentalomas and autonomous cortisol secretion (ACS). DESIGN: Cohort study. SETTING: University hospital. PATIENTS: Patients (n = 302) with incidentally discovered adrenal masses, divided into unilateral adenoma and hyperplasia with ACS (n = 46 and n = 52, respectively) and NS (n = 120 and n = 84, respectively). Post-dexamethasone suppression test (DST) cortisol <50 or >50 nmol/L defined NS and ACS, respectively. INTERVENTION: Analysis of 10-steroid panel by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and clinical data (mean follow-up 39 months). MAIN OUTCOME MEASURES: Difference in baseline and post-DST steroid profiles between groups. Correlation with cardiovascular profile. RESULTS: Patients with unilateral adenomas and ACS showed higher cortisol, 11-deoxycortisol, and corticosterone and lower dehydroepiandrosterone than those with NS adenomas. Patients with ACS hyperplasia showed higher cortisol and lower androgens in women than those with NS. Patients with ACS had reduced suppression of post-DST cortisol, 11-deoxycortisol, and corticosterone, irrespective of adrenal morphology. Post-DST cortisol and corticosterone were associated with higher prevalence of severe/resistant hypertension. Patients with ACS unilateral adenomas showed higher incidence of worsening of hypertensive disease and novel cardiovascular events than those with NS, with post-DST cortisol [hazard ratio (HR) 1.02; 95% CI, 1.01 to 1.03; P < 0.001] and baseline corticosterone (HR 1.06; 95% CI, 1.01 to 1.12; P = 0.031) among the main predictors. CONCLUSIONS: Patients with adrenal incidentalomas showed different steroid profiles, depending on functional status and adrenal morphology, with implications for their cardiovascular status.

RESUMO

Polycystic ovary syndrome (PCOS) is a common disorder with a high phenotypic variability. Frequently, it is associated with a mild to moderate insulin resistance (IR) caused by an interaction between polygenic diathesis and the environment. However, PCOS may be a complication of an underlying syndrome of severe IR such as insulin receptor autoantibodies, mutations in the insulin receptor or in the signalling pathway downstream from the insulin receptor or, most frequently, a defect in function or in the development of the subcutaneous adipose tissue. Such conditions are clinically characterized by lipodystrophy. Lipodystrophy in some cases is produced by a single-gene defect. In our experience, PCOS secondary to a missense mutation in the LMNA gene, known as familial partial lipodystrophy type 2 (FPLD2), is the most frequent form of PCOS secondary to severe IR due to genetically determined lipodystrophy. These forms should be identified as they benefit from tailored therapies.

RESUMO

Hyperandrogenic disorders have been associated with psychological distress, reduced quality of life, anxiety and depression. The hypothalamic-pituitary-adrenal (HPA) axis plays a pivotal role in the adaptive response to stressor events. Salivary cortisol (SalF) and cortisone (SalE) testing have been proven to be useful in the evaluation of HPA-axis activity. This study investigated whether SalF and SalE responses to two putative stressor levels differed between the hyperandrogenic states in late adolescent and young women, thus measuring the HPA-axis adaptive response to acute stress events. We selected 161 drug-free females aged 16-19 years from a large population previously enrolled in a cross-sectional epidemiological study. Saliva was collected in the morning before and after two putative stressor events consisting in a self-filled questionnaire (weaker stressor) and in a structured interview plus physical examination by an endocrinologist (stronger stressor). SalF and SalE, as well as blood steroids, were assessed by liquid chromatography-tandem mass spectrometry. Subjects were subdivided into different groups according to the presence of: isolated menstrual irregularities (MI, oligo-amenorrhea; n = 22), isolated hirsutism (HIR, modified Ferriman-Gallwey score ≥ 8; n = 26), isolated hyperandrogenaemia (HT, testosterone >0.438 ng/mL; n = 14), and polycystic ovary syndrome (PCOS, MI with HIR and/or HT, n = 16). The remaining 83 apparently healthy subjects were used as controls. SalF and SalE significantly decreased after the weaker stressor, following the physiologic diurnal loss, in all the groups except for isolated HIR, where they remained unchanged (P = 0.091 and P = 0.118, respectively). In contrast, SalF and SalE remained unchanged after the stronger stressor in isolated MI, isolated HT and controls, whereas SalF increased significantly in isolated HIR (P = 0.011), and SalE increased significantly both in isolated HIR (P = 0.005) and in PCOS (P = 0.011) groups. SalF percentage variation in response to the stronger stressor was positively associated with systolic blood pressure in PCOS (P = 0.018), and both SalF and SalE percentage variations were positively associated with diastolic blood pressure in the isolated HIR group (P = 0.010 and P = 0.006, respectively). In addition, in the isolated HIR group, the SalF percentage variation was negatively associated with HDL cholesterol levels (P = 0.005). Finally, SalF and SalE percentage variations were positively associated with circulating androstenedione (P = 0.031 and P = 0.011, respectively) and DHEA (P = 0.020 and P = 0.003, respectively) in the isolated HIR group. In conclusion, this study demonstrates that hirsute and PCOS adolescent and young women are characterized by HPA-axis overactivity in response to stressful stimuli, as detectable by salivary glucocorticoid measurements. These data also indicate that the higher the HPA-axis activity, the higher the adrenal androgen output and the worse the metabolic profile.

RESUMO

This paper represents an international collaboration of paediatric endocrine and other societies (listed in the Appendix) under the International Consortium of Paediatric Endocrinology (ICPE) aiming to improve worldwide care of adolescent girls with polycystic ovary syndrome (PCOS)1. The manuscript examines pathophysiology and guidelines for the diagnosis and management of PCOS during adolescence. The complex pathophysiology of PCOS involves the interaction of genetic and epigenetic changes, primary ovarian abnormalities, neuroendocrine alterations, and endocrine and metabolic modifiers such as anti-Müllerian hormone, hyperinsulinemia, insulin resistance, adiposity, and adiponectin levels. Appropriate diagnosis of adolescent PCOS should include adequate and careful evaluation of symptoms, such as hirsutism, severe acne, and menstrual irregularities 2 years beyond menarche, and elevated androgen levels. Polycystic ovarian morphology on ultrasound without hyperandrogenism or menstrual irregularities should not be used to diagnose adolescent PCOS. Hyperinsulinemia, insulin resistance, and obesity may be present in adolescents with PCOS, but are not considered to be diagnostic criteria. Treatment of adolescent PCOS should include lifestyle intervention, local therapies, and medications. Insulin sensitizers like metformin and oral contraceptive pills provide short-term benefits on PCOS symptoms. There are limited data on anti-androgens and combined therapies showing additive/synergistic actions for adolescents. Reproductive aspects and transition should be taken into account when managing adolescents.

RESUMO

PCOS is a clinical heterogeneous entity of female androgen excess diagnosed by exclusion of other disorders responsible for androgen excess. The concept of secondary PCOS implies that there is a primary well-defined cause leading to the PCOS phenotype with underlying androgen overproduction, regardless of the origin. In these cases, we presume the term of 'secondary PCOS' could be used. In all these conditions, the potential complete recovery of the hyperandrogenemic state as well as the remission of the PCOS phenotype should follow the removal of the cause. If accepted, these concepts could help clinicians to perform in-depth investigations of the potential factors or disorders responsible for the development of these specific forms of secondary PCOS. Additionally, this could contribute to develop further research on factors and mechanisms involved in the development of the classic and the nonclassic PCOS phenotypes.

RESUMO

OBJECTIVE: This study was designed to assess the steroid profiling by liquid chromatography coupled with tandem mass spectrometry in PCOS women with different phenotypes. DESIGN: Cross-sectional study. SETTING: University hospital of Bologna, Italy. PATIENTS AND METHODS: A total of 156 PCOS women and 141 controls comparable for age were investigated. All underwent a steroid profiling by liquid chromatography coupled with tandem mass spectrometry. Metabolic parameters were also investigated and hirsutism was measured by the modified Ferriman-Gallwey (mF-G) score. RESULTS: Three distinct phenotypes were initially defined according to the combination of hirsutism (mF-G ≥ 8) and/or high testosterone (T) (HA), oligo-amenorrhea (OA), and polycystic ovarian morphology (PCOm); OA + PCOm (n = 43), HA + OA (n = 65), and HA + OA + PCOm (n = 45). T, androstenedione (A), and free androgen index (FAI) levels progressively increased in the 3 PCOS phenotypes with respect to the controls, with the highest values in the HA + OA + PCOm phenotype. The various combinations of hirsutism, high T, high A, and high FAI made it possible to categorize the 3 original phenotypes into 8 hyperandrogenic subgroups, characterized by divergent additional steroid profile and metabolic pattern. A total of 90% of patients with PCOS thus proved hyperandrogenic. Interestingly, half the PCOS women originally classified as having the OA-PCOm phenotype were categorized in a hyperandrogenic subgroup. No significant correlation was found between T, A, and the mF-G score. In contrast, significant correlation was found between A and both T and FAI. CONCLUSIONS: This study provides evidence that, by including a steroid profile in the definition of hyperandrogenemia, the majority of women with PCOS are hyperandrogenic, although a clinical and biochemical heterogeneity exists. In addition, these data demonstrate that hirsutism and high androgen levels cannot be used indifferently to define hyperandrogenism.

RESUMO

OBJECTIVE: The aim of this study was to evaluate differences in anti-müllerian hormone (AMH) and insulin-like 3 (INSL3) levels and their association with gonadotropin and ovarian steroid hormones, as expression of ovarian function, between healthy normal-weight ovulatory and anovulatory eumenorrheic late adolescent females. STUDY DESIGN: This study analyzed AMH and INSL3 levels in forty healthy eumenorrheic late adolescent females (aged 16-19 ys), selected from a cross-sectional epidemiological study performed on the prevalence of hyperandrogenic states. The subjects were divided into ovulatory (n: 28) and anovulatory (n: 12) groups in accordance to a previous cluster analysis based on progesterone (P) distribution measured once in the latter part of the cycle. Both groups were compared for anthropometric, biochemical and hormonal parameters. RESULTS: INSL3 and AMH were detectable in all samples. Testosterone (P=0.01), the free-androgen index (FAI) (P=0.051), gonadotropins (LH: P=0.02; FSH: P=0.004) and AMH (P=0.02) levels were significantly higher in the anovulatory group with respect to their ovulatory counterpart. A trend toward significantly higher INSL3 concentrations (P=0.08) was also shown in the anovulatory group. A positive correlation between INSL3 levels and androgens such as androstenedione (r=0.38; P=0.02), testosterone (r=0.44; P=0.004) and FAI (r=0.42; P=0.006) and a negative borderline significant correlation (r=-0.30; P=0.055) between AMH and P were shown in all subjects. CONCLUSION: Healthy eumenorrheic late adolescent females with sporadic anovulation display higher AMH and INSL-3 blood concentrations in association with higher androgen levels compared with age- and BMI-matched subjects with ovulatory cycle, suggesting evidence of an earlier ovarian dysfunction.

RESUMO

OBJECTIVE: The psychosocial implications of polycystic ovary syndrome (PCOS) phenotypes have been investigated in different patient populations, but little attention was paid to adolescent and young women. The aim of this study was to evaluate the psychosocial correlates of PCOS and other hyperandrogenic states in a population of late adolescent and young females and to provide a psychological characterization of specific clinical hyperandrogenic phenotypes. DESIGN: This was a cross-sectional study. PATIENTS: High school female students, aged 16-19 years. MEASUREMENTS: The study protocol was designed with three possible levels of participation characterized by an increased level of commitment. For the specific purposes of this investigation, we focused on the subsamples of students whose clinical state was assessed by medical examination (n = 835) and for whom additional laboratory tests were available (n = 394). Psychological evaluation encompassed psychological distress, levels of stress, well-being, illness behaviour and quality of life (as measured by the Symptom Questionnaire, the Psychosocial Index and the Psychological Well-Being scales). RESULTS: Significantly higher levels of psychological distress and impaired well-being and quality of life were found among late adolescent and young women with isolated clinical hyperandrogenism compared to their normal counterparts. Furthermore, females with PCOS showed significantly greater hostility/irritability compared to healthy control subjects. CONCLUSIONS: These findings highlight the importance of early recognizing and adequately managing psychological distress in such patients.

RESUMO

The polycystic ovary syndrome is the commonest hyperandrogenic and dysmetabolic disorder in women that, by definition, may present with different phenotypes, including the classic forms and those with a milder presentation. Its diagnosis is mainly based on careful clinical judgment, although it may require additional investigation by blood testing or imaging techniques in the differential diagnosis of androgen excess. This article summarizes the most important aspects of the diagnostic procedure and suggests how to apply them in clinical practice.
