肥胖与青少年多囊卵巢综合征

多囊卵巢综合征（PCOS）是育龄妇女常见生殖内分泌疾病。近年发现,随着儿童肥胖患病率增加,青少年PCOS发病率也逐年提高。肥胖可通过增加外周循环胰岛素水平影响PCOS发病机制,PCOS患者高雄激素血症也会增加内脏脂肪沉积。肥胖会增加与PCOS相关的代谢和心血管方面的并发症的患病风险,如胰岛素抵抗（IR）、高脂血症、高血压以及临床症状不明显的动脉粥样硬化等。早期识别青春期PCOS,有利于及时纠正、阻断其内分泌紊乱,防止近期及远期并发症发生。

Polycystic Ovary Syndrome among Obese Adolescents

Background and aims: In adolescence and obesity, the pathophysiology of polycystic ovary syndrome (PCOS) is very difficult to distinguish. We aimed to assess the diagnosis of PCOS in the population of obese adolescent.

Methods: Cross-sectional study. Setting: Pediatric Endocrinology Weight and Management Clinic from Children's Institute, São Paulo, Brazil. Participants: Forty-nine post-menarcheal obese adolescents with mean age of 14.7 years. Interventions: Anthropometric assessment and review of medical records were done. Clinical and laboratory hyperandrogenism were quantified using Ferriman–Gallwey index and androgenic dosages, respectively. Ovarian morphology was evaluated through suprapubic ultrasonography.

Results: By the 2015 Witchel et al. guideline for PCOS in adolescence, 18.4% were diagnosed as having PCOS. When assessed by Rotterdam, Androgen Excess and PCOS Society, and American National Institute of Health criteria's, 26.4%, 22.4%, and 20.4% had PCOS, respectively. Irregular menstrual cycles were found in 65.3% of patients. Clinical hyperandrogenism was observed in 16.3% of girls and 18.4% had elevated serum androgen values. Suprapubic ultrasonography revealed enlarged ovaries in 18.4% of the adolescents.

Conclusions: PCOS in all-comers obese adolescents from a Weight and Management Clinic in a quaternary hospital is more frequent when compared to adult women showed in the literature.     

Self-Concept,Depression, and Anxiety Levels of Adolescents with Polycystic Ovary Syndrome

Study ObjectiveIn this study we explored the level and severity of issues related to self-concept, depression, and anxiety in adolescents with polycystic ovary syndrome (PCOS).DesignCross-sectional and case-control study.SettingThe research was conducted in the outpatient Pediatric Endocrinology Clinic of Adiyaman University School of Medicine in Turkey.ParticipantsThe study population comprised 153 patients with PCOS and 161 healthy adolescents.Interventions and Main Outcome Measures: The Personal Information Form, State-Trait Anxiety Inventory for Children, Children's Depression Inventory, and Piers-Harris Children's Self-Concept Scale were administered to all of the participants who took part in the study.ResultsThe Piers-Harris Children's Self-Concept Scale scores were lower in the PCOS group than in the control group (P < .001). In addition, the scores for the Children's Depression Inventory were also significantly higher in the PCOS group (P < .001). The State-Trait Anxiety Inventory for Children scores showed statistically significant higher levels of state anxiety and trait anxiety in the PCOS group (P < .001).ConclusionAdolescents with PCOS had lower self-concept scores, greater anxiety levels, and increased depressive symptoms than the healthy controls. Future studies are needed to examine the psychiatric problems in adolescents with PCOS.     

Characteristics of Adolescents with Differing Polycystic Ovary Syndrome Phenotypes

Study ObjectiveTo analyze clinical, metabolic, hormonal, and ultrasound characteristics of adolescents with polycystic ovary syndrome phenotypes.DesignWe performed a retrospective analysis of quality improvement data. We divided patients according to phenotype on the basis of clinical or biochemical diagnosis of hyperandrogenism (HA), irregular menstruation (IM), and presence or absence of polycystic ovarian morphology (PCOM) on pelvic ultrasound (PUS) images, if obtained. The 5 resulting groups were: (1) HA/IM/normal PUS, n = 28; (2) HA/PCOM, n = 10; (3) IM/PCOM, n = 18; (4) HA/IM/PCOM, n = 40; and (5) HA/IM/no PUS obtained, n = 80. We compared parameters between groups using the nonparametric Wilcoxon rank sum test.SettingBoston Children's Hospital, 2012-2016.ParticipantsOne hundred seventy-six girls and young women aged 11-25 years.InterventionsNone.Main Outcome Measures(1) Clinical, metabolic, and hormonal characteristics; and (2) PUS measurements.ResultsGroups with HA had significantly higher acne scores, Ferriman-Gallwey scores, and total and free testosterone concentrations than groups without HA. Significant differences in hemoglobin A1c were found between the IM/PCOM and HA/IM/PCOM groups (5.1% vs 5.3%; P = .01) and the IM/PCOM and HA/IM/no PUS groups (5.1% vs 5.3%; P < .01). In patients who had ultrasound performed, 49/94 (52.1%) met PCOM criteria on the basis of ovarian size, 37/94 (39.4%) on the basis of follicle number, and 27/94 (28.7%) on both; 10/94 (10.5)% had incidental findings on ultrasound, with 2 patients requiring further management.ConclusionLimited differences in clinical, metabolic, and hormonal characteristics exist between adolescents with different phenotypes of polycystic ovary syndrome, and are mostly related to the presence or absence of HA. Of patients with ultrasound examinations, only 2 had clinically actionable incidental findings.     

Clinical and Metabolic Features of Polycystic Ovary Syndrome among Chinese Adolescents

ObjectivesTo explore the clinical and metabolic features exhibited by Chinese adolescents with polycystic ovary syndrome (PCOS) and to determine the differences between nonobese and obese adolescent patients with PCOS.DesignClinical cross-sectional study.SettingDepartment of Gynecology and Reproductive Center.Participants25 obese and 66 nonobese adolescents with PCOS and 26 age-matched controls.InterventionsFasting venous blood samples and an oral glucose tolerance test using 75 g of glucose were obtained from PCOS patients and controls.Main Outcome MeasuresClinical features were summarized. Serum levels of FSH, LH, E₂, TT, SHBG, fasting insulin, and fasting glucose were measured.ResultsThe prevalence of obesity in adolescents with PCOS was 27% (25/91). 99% of these patients presented with menstrual disorders, 84% presented with clinical and/or biochemical hyperandrogenism, and 90% exhibited an ultrasonographic appearance of polycystic ovaries. The prevalence of hirsutism and acanthosis nigricans were higher in the obese PCOS group than in the nonobese PCOS group (72% vs 41% and 44% vs 5%, respectively). A total of 5 of 20 obese (25%) and 5 of 36 nonobese patients (14%) demonstrated impaired glucose tolerance levels.ConclusionsChinese adolescents with PCOS manifest clinical and metabolic features similar to those of adult Chinese women with PCOS except for the increased prevalence of hyperandrogenism and insulin resistance. Adolescents with high risk factors, especially those with menstrual disorders and hyperandrogenism, may need careful clinical screening.     

Twelve-month Continuation of the Etonogestrel Implant in Adolescents With Polycystic Ovary Syndrome

Study ObjectiveTo identify why adolescents with polycystic ovary syndrome (PCOS) chose the etonogestrel (ENG) contraceptive implant, to determine the 12-month continuation rate, and to characterize factors related to discontinuation.Design, Setting, and ParticipantsRetrospective chart review of adolescents seen at a tertiary care children's hospital between July 1, 2008, and August 30, 2019, with PCOS diagnosis confirmed per National Institutes of Health criteria and ≥12-month ENG follow-up.Interventions and Main Outcome MeasuresDemographic characteristics, reasons for ENG insertion and removal, and information on other hormonal/contraceptive therapies were collected. Patients were categorized as ENG continuers (use ≥12 months) or discontinuers (removal at <12 months), and groups were compared.ResultsA total of 96 patients met inclusion criteria (age 17.7 ± 2.2 years, body mass index 34.8 ± 8 kg/m²). Reasons for ENG were documented in 74% (51% contraception, 32% ease of use, 15% other, 13% estrogen avoidance). In all, 27% had never been sexually active, and 67% had had prior sexual activity. Treatments prior to ENG placement included 74% combined hormonal contraception, 20% medroxyprogesterone acetate withdrawal, and 17% depot medroxyprogesterone. A total of 77% continued ENG at 12 months. The main reasons for discontinuation were bleeding (41%), concern about weight gain (23%), and mood changes (18%). No preimplantation characteristics were independently predictive of continuation, although 100% of patients with type 2 diabetes (n = 11) continued. Patients who sought additional care, including telephone calls (41% vs 12%, P = .006) and clinic visits (64% vs 20%, P < .001) were more likely to discontinue.ConclusionsThe ENG implant was well tolerated in adolescents with PCOS and similar to published 12-month continuation rates.     

Differences in the Management of Adolescents with Polycystic Ovary Syndrome across Pediatric Specialties

Study ObjectiveEvaluate for differences in the management of adolescents with polycystic ovarian syndrome (PCOS) across 3 pediatric specialties.DesignRetrospective review of medical records.SettingAcademic children’s hospital.Participants181 adolescents seen between July 2008 and June 2010 by providers in Pediatric Endocrinology (PEndo), Adolescent Medicine (AMed), or Pediatric and Adolescent Gynecology (PGyn) identified via billing data (ICD-9 code for PCOS, 256.4).InterventionsNone.Main Outcome Measures(1) Percentage of adolescents with a billing diagnosis of PCOS who met diagnostic criteria; (2) Percentage of individuals screened for comorbidities and differences across specialties; (3) Differences in treatment recommendations across specialties; (4) Factors associated with recommendation for metformin and hormonal contraceptives.ResultsThirteen percent of PEndo patients did not meet diagnostic criteria for PCOS; 20% of AMed and PGyn patients did not meet criteria. There were significant differences in rates of screening for obesity, insulin resistance, and Type 2 diabetes. There were significant differences in treatment recommendations for lifestyle changes, metformin, and anti-androgen therapy across specialties. Specialty and obesity were significant predictors of metformin recommendation; specifically PEndo predicted metformin recommendation. PGyn and AMed specialties predicted hormonal contraceptive recommendation.ConclusionsThe variability observed among specialties may be due to differences in training, accounting for a range of comfort with aspects of PCOS. Formulation of consensus guidelines for diagnosis and management of PCOS are needed, along with broad educational efforts. By correctly diagnosing, screening for comorbidities, and managing PCOS appropriately during adolescence, providers may reduce the risk for long-term consequences.     

Factors Contributing to Initial Weight Loss Among Adolescents with Polycystic Ovary Syndrome

Study ObjectiveTo evaluate the impact of a multidisciplinary clinic on weight management among adolescents with PCOS.Design140 adolescent females were evaluated in a multidisciplinary PCOS clinic from March 2005 to December 2008. The team included a pediatric endocrinologist, health psychologist, dietitian, and pediatric gynecologist. 110 were diagnosed with PCOS based on the Rotterdam Criteria. Height, weight, BMI, number of subspecialists seen, use of metformin, and compliance with return visits were obtained from medical records.SettingAmerican Family Children's Hospital in Madison, Wisconsin.Participants110 adolescent females with polycystic ovary syndrome.InterventionsConsultation with a dietitian and health psychologist.Main Outcome MeasureChange in weight.ResultsThe average age at first visit was 15.9 years. The average BMI was 34.7 kg/m² (range 18.1-55.5). Seventy-six percent had an initial BMI above the 95^th percentile. Interactions with providers at the initial visit included a pediatric endocrinologist (100%), health psychologist (60.9%), dietitian (75.5%) and gynecologist (70.9%). Seventy one percent returned for a follow-up visit, (average time of 4.5 months between visits) with 57% achieving weight loss (average 3.5 kg) and an additional 12.6% demonstrating no significant weight gain (< 1.5 kg). Thus, 69.6% demonstrated weight loss/stabilization.ConclusionsIn this multidisciplinary clinic for adolescents with PCOS, nearly 70% of patients succeeded in short-term weight stabilization, with 57% demonstrating weight loss. Interactions with the health psychologist and dietitian appeared to play a key role in successful weight control, supporting the importance of psychology and nutrition expertise in the management of this disorder.     

Ovulation and the Polycystic Ovary Syndrome

Summary: In the 1930s, Stein and Leventhal added amenorrhoea to anovulatory dysfunctional uterine bleeding among the known clinical manifestations of the polycystic ovary syndrome (PCOS). Whatever the menstrual pattern, infrequent or absent ovulation with symmetrical enlargement of the ovaries is now a familiar abnormality in women of reproductive age. Diagnosis of PCOS has developed from just the clinically obvious to an appreciation, through ultrasound imaging of the ovaries and endocrine testing, of its subtler forms. Today's clinicians will identify PCOS on the ultrasound image of many small follicles apparent in the periphery of both ovaries, on raised serum unbound testosterone assays, on exaggeration of serum LH levels with the start of pulsatile GnRH therapy, and on follicular overresponsiveness to injections of FSH. Once among the most treatable causes of infertility, ovulation-induction for PCOS remained unsophisticated while microsurgery and assisted conception dissolved frontiers for other causes of infertility. Whereas we now have the benefit of high technology embryo cryostorage to cope with embarassingly high yields of PCOS oocytes, we still need to explain why, the bigger the ovaries, the more likely (we have long known it to be) that PCOS can be cured simply by reducing ovarian mass. Some cases of PCOS are hereditary and most seem constitutionally determined. PCOS is so common that the questions must be asked, Are we appreciating an extreme of normal? Could the milder forms of PCOS have - or could PCOS have had - evolutionary usefulness?     

The Predictive Role of Serum Cystatin C Levels in Polycystic Ovary Syndrome in Adolescents

Study ObjectiveTo evaluate the correlation between serum cystatin levels and clinical parameters in adolescents with polycystic ovary syndrome (PCOS).Design, Setting, Participants, Interventions, and Main Outcome MeasuresThis prospective case-control study included 89 adolescents with PCOS. Demographic characteristics and hormonal and biochemical parameters were compared between study (89 patients with PCOS) and control (84 subjects without PCOS) groups. Risk factors recorded were age, body mass index (BMI), waist to hip ratio (WHR), Ferriman–Gallwey score, triglyceride, total cholesterol, high-density lipoprotein, low-density lipoprotein (LDL), high-sensitivity C-reactive protein, cystatin C, follicle stimulating hormone, luteinizing hormone, estradiol, dehydroepiandrosterone sulfate, homeostatic model assessment insulin resistance index, free testosterone, and progesterone levels.ResultsBMI, WHR, Ferriman–Gallwey score, and triglyceride, LDL, total cholesterol, estradiol, dehydroepiandrosterone sulfate, free testosterone, luteinizing hormone, high-sensitivity C-reactive protein, and cystatin C levels, and homeostatic model assessment insulin resistance index scores were significantly higher, and high-density lipoprotein levels were lower in the PCOS patients compared with healthy subjects (P < .05). We also found positive correlations between the cystatin C levels and BMI, WHR, estradiol, high-sensitivity C-reactive protein, and LDL levels in the study group.ConclusionThe serum cystatin C level is a promising marker for diagnosing adolescent patients with PCOS and suggests an inflammatory etiology for these patients. Further studies with more participants should examine this potential association with inflammation.
