RESUMO

PURPOSE OF REVIEW: This article reviews how to address contraception in young women with type 2 diabetes (T2D). The presence of obesity and comorbidities associated with insulin resistance increases the risk of thromboembolic disease and adverse cardiovascular outcomes. RECENT FINDINGS: Recent studies have shown that adolescents with T2D are at high risk of unintended pregnancy with poor outcomes for the mother and offspring. Adolescents with T2D without severe obesity, micro- or macrovascular disease, or other cardiovascular risk factors can use any contraceptive method. However, only nonhormonal or progestin-only methods may be used when morbid obesity, severe hypertension, micro- or macrovascular disease, or multiple cardiovascular risk factors are present. The medical team must provide preconceptional counseling and contraception to reduce adolescent pregnancies in young women with T2D. Progestin-only or nonhormonal long-acting reversible contraception (LARC) should be recommended for women with T2D with compliance issues or adverse cardiovascular risk profiles.

RESUMO

CONTEXT: An association between premature adrenarche and metabolic syndrome at presentation has been described. Our aim was to assess whether the presence of high dehydroepiandrosterone sulphate (DHEAS [HD]) at the adrenarche determines the risk of metabolic syndrome during puberty, taking into account body mass index (BMI) and birth weight. DESIGN: Prospective observational. PATIENTS: Five hundred four girls from the Growth and Obesity Chilean Cohort Study were followed from birth through puberty. At age ~7, subjects were classified by DHEAS concentrations into the HD (>75th percentile) or normal DHEAS (ND, ≤75th percentile) subgroups. MEASUREMENTS: Anthropometrics, semiannual clinical pubertal staging and hormonal and metabolic levels. The relationships among DHEAS at age ~7, metabolic syndrome, and each of its components independently, were analyzed by linear and logistic regression models during puberty and 1-year postmenarche, adjusted by confounders. RESULTS: Girls with HD at 7 years exhibited higher BMI, more central fat and higher serum androgen and insulin like growth factor (IGF)-I levels throughout puberty. Also, girls with HD had a greater prevalence of hyperglycemia at B2 and B4 breast stages, and of low HDL at B4. At 1 year after menarche, HD girls had a higher prevalence of metabolic syndrome, and those with BMI > 1 SD score had a higher metabolic score and insulin levels than ND girls with similar BMI. CONCLUSIONS: Our observations suggest that girls with HD at the age of adrenarche may be at greater risk for metabolic syndrome at adolescence, especially in those who are overweight or obese. Our results emphasize the importance of lifestyle interventions for childhood overweight and obesity among girls with HD.

RESUMO

Adolescent pregnancy is a major public health problem worldwide. Adolescents living with diabetes are not aware of the risks of unplanned pregnancy and the high rate of fetal and maternal complications when gestation occurs in women with significant hyperglycemia. These data highlight the significance of pregnancy prevention in young women with diabetes. Long-acting reversible contraceptives (LARCs), which include subdermal progestin implants and hormonal and nonhormonal intrauterine devices (IUDs), have been recommended by the American College of Obstetricians Gynecologists and the American Academy of Pediatrics as a first-line contraceptive option for adolescents and young women. This article reviews LARC options for adolescents and young women with type 1 (T1D) and type 2 (T2D) diabetes as well as the possible complications and side effects.

RESUMO

STUDY OBJECTIVE: To assess pubertal events in a Hispanic female population and to create normograms of puberty. DESIGN: Longitudinal. SETTING: University facility. PARTICIPANTS: Five hundred forty-nine girls from the Growth and Obesity Chilean Cohort study. INTERVENTIONS: Follow-up twice a year beginning at age 6 years. MAIN OUTCOME MEASURES: Breast development, pubic hair development, and age. Breast development (B2, B3, and B4) and pubarche (P2) were determined. Age at menarche was obtained from the adolescents and their mothers. Age and growth velocity at peak height velocity were calculated. RESULTS: In girls, B2, B3, and B4 occur at median ages of 9.2, 10.2, and 10.9 years, respectively. The median age at P2 was 9.7 years. The mean age at peak height velocity and the growth velocity were 10.6 years (SD = 1.1) and 8 cm/y, respectively. The mean age at menarche was 11.9 years (SD = 1.1); only 2.8% (15 /530) of girls experienced menarche after 14 years and 1.9% before 10 years. The mean interval time between B2 and menarche was 2.5 ± 1.0 years. Transient thelarche occurred in 8.6% of girls. CONCLUSION: This longitudinal cohort shows that thelarche occurred 1.2 months later than previously reported in cross-sectional studies. Conversely, we found that pubic hair appeared 12 months earlier and menarche occurred 9 months earlier than previously reported. These findings are important in setting normalcy data and avoiding unnecessary clinical consultations.

RESUMO

OBJECTIVE: To assess whether the presence of high DHEAS (HD) at 7 years determines different timing, sequence, and rate of pubertal events, and whether it is associated with adrenal and/or ovarian hyperandrogenism and changes in ovarian morphology throughout puberty. METHODS: In a longitudinal study of 504 girls, clinical evaluation was performed every 6 months after 7 years of age to detect Tanner stages; hormonal and anthropometric measurements were conducted at thelarche (B2), breast Tanner 4 (B4), and 1 year after menarche; ultrasonographic evaluation was also performed after menarche. The girls were classified as HD if their DHEAS level was >42.1 µg/dL (>75th percentile) around 7 years. RESULTS: HD around 7 years is associated with a younger age at thelarche, pubarche, and menarche. Girls with HD had higher androstenedione and total testosterone levels, and a higher free androgen index (FAI), and lower levels of antimüllerian hormone (AMH) at B2, and higher levels of androstenedione and FAI at B4 and after menarche. All these results were significant even after adjusting for body mass index, age at first DHEAS determination, and birth weight. One year after menarche, polycystic ovarian morphology was detected in 7.6 and 7.3% of the HD and the normal DHEAS group, respectively. Ovarian volume was correlated with AMH, testosterone, androstenedione, and LH but not with DHEAS around 7 years. CONCLUSION: Prepubertal HD in normal girls was associated with earlier thelarche, pubarche, and menarche, and a mild androgen increase throughout puberty. We believe continuous follow-up of this cohort is important to prospectively address the interrelationships between biochemical adrenarche and early growth as determinants of ovarian function.

RESUMO

BACKGROUND: The ultrasonographic criteria used to identify polycystic ovarian morphology (PCOM) during adolescence have changed over time. Recently, a Worldwide Pediatric Consensus (PedC) defined PCOM using stricter criteria than the previous recommendations of the Rotterdam Consensus (RC) and Androgen Excess-Polycystic Ovarian Syndrome Society (AES/PCOS) criteria. The aim of this study was to determine the prevalence of PCOM in healthy adolescents according to the 3 reported diagnostic criteria and compare the hormonal profile in females with and without PCOM based on the PedC criteria. METHODS: Nonobese adolescents (n = 102) with regular menstrual cycles were studied. Transabdominal ultrasound and hormonal profiles were assessed during the follicular phase. PCOM was defined on the basis of the 3 published criteria. RESULTS: On the basis of the PedC, RC, and AES/PCOS criteria, PCOM was diagnosed in 13, 34, and 24% of adolescents, respectively. Adolescents with and without PCOM according to the PedC criteria had similar androgen levels. Serum anti-Müllerian hormone (AMH) levels were elevated in adolescents with PCOM, irrespective of the criteria used. CONCLUSIONS: Use of the new PedC diagnostic criteria for PCOM results in a lower prevalence of this ultrasonographic pattern in adolescents, but this condition is not associated with hyperandrogenism. Elevated AMH is associated with PCOM in adolescents regardless of the criteria used to determine the ultrasonographic pattern.

RESUMO

We evaluated the association of hirsutism and oligomenorrhea (persistent menstrual cycles > 45 days) as screening criteria for the detection of biochemical hyperandrogenism (BH) and polycystic ovaries (PCOM) during adolescence and determined which androgens, granulosa cell hormone, ultrasonographic parameters have the best association with polycystic ovary syndrome (PCOS). Hirsute girls with oligomenorrhea (N = 26 Hirs/Oligo group) and non-hirsute girls with regular cycles (N = 63, C group) were studied. Prevalence of BH and PCOM, diagnostic performance of androgens and ultrasound parameters for PCOS diagnosis were analyzed. BH and PCOM prevalence were higher in the Hirs/Oligo girls than in the C girls (76.9% versus 25.5%; 92.3% versus 33.3%, respectively; p < 0.0001). A complete PCOS phenotype (Hirs/Oligo with BH and PCOM) was observed in 73.1% of the Hirs/Oligo group. The presence of both BH and PCOM was observed in 7.9% of the C group. The parameters with the best diagnostic performance were free androgen index ≥6.1, testosterone ≥2.4 nmol/L, follicle number ≥12 and ovarian volume ≥10 ml anti-Müllerian hormone (AMH) exhibited a low diagnostic accuracy. Hirsutism and persistent menstrual cycle over 45 days are highly associated with BH and PCOM suggesting that the presences of both criteria are necessary for the diagnosis of PCOS during adolescence.

RESUMO

La sospecha de Síndrome de Ovario Poliquístico es un motivo de consulta frecuente durante la adolescencia, esto probablemente está dado por la sobreposición de las características fisiológicas de este período con los criterios diagnósticos tradicionalmente usados para definir este síndrome, tales como ciclos menstruales irregulares, hiperandrogenismo y morfología ecográfica de ovario poliquístico. Es por esto que parece importante discutir si los criterios diagnósticos de Síndrome de Ovario Poliquístico aplicados en mujeres adultas pueden extrapolarse a los primeros años postmenarquia. En este artículo se discute el diagnóstico de Síndrome de Ovario Poliquístico en la adolescencia, sus controversias y su manejo.


The suspicion of polycystic ovary syndrome is a common complaint during adolescence, and is probably given by the overlap of physiological characteristics of this period of life with the diagnostic criteria traditionally used to define this syndrome, such as irregular menstrual cycles, hyperandrogenism and polycystic ovarian morphology. This is why it seems important to discuss whether these diagnostic criteria for polycystic ovary syndrome in adults can be extrapolated to the early years postmenarche. This article will discuss the diagnosis of polycystic ovary syndrome in adolescence, their controversies and their management.

RESUMO

INTRODUCTION: Variations in inflammatory markers have been reported in adult women during the luteal phase, but whether these findings are observed during adolescence is unknown. We postulate that higher ultrasensitive C-reactive protein (usCRP) and lower 2-hydroxyestrone (2OHE) levels, an estrogen metabolite with cardioprotective actions, are present during the luteal phase in young women. AIM: To evaluate usCRP levels during the menstrual cycle and to determine its association with 2OHE and 16α-hydroxyestrone (16OHE) in adolescents. METHODS: Healthy postmenarcheal adolescents (N = 37) were studied during one menstrual cycle in follicular phase (FP) and luteal phase-like period (LP-L). RESULTS: Elevations in usCRP levels in the LP-L were observed in the entire group and in anovulatory cycles (1.9 ± 1.1 mg/L in FP to 2.5 ± 1.8 mg/L in LP-L; p < 0.0001). Increases in estrone, estradiol, free and bioavailable estradiol, testosterone, usCRP and 2OHE levels were observed in LP-L compared with FP (p < 0.01), with a borderline elevation in IFG-I levels (p = 0.06). CONCLUSIONS: We report an elevation of usCRP and 2OHE levels during the luteal phase in healthy adolescents. Elevations of this inflammatory marker in anovulatory adolescents without an increase in 2OHE may play a role in metabolic risks associated with chronic anovulation.

RESUMO

INTRODUCTION: Chlamydia trachomatis and Neisseria gonorrhoeae are responsible for 3-10% of sexually transmitted diseases in adolescents. 75% are asymptomatic. International standards recommend annual screening for C. trachomatis in sexually active women under 26 years. Self-collected vaginal swab is one of the less invasive screening methods, it is well accepted by patients and rarely used in our country. AIM: To determine the frequency of C. trachomatis and n. gonorrhoeae by a self-sampling method of vaginal swab and its acceptability in a group of adolescents and young adults. PATIENTS AND METHODS: Women 18 to 25 years old. Vaginal samples were processed by nucleic acid amplification tests, Gen Probe APTIMA Combo2. Data were collected on sexual behavior and perception of self-sampling by survey. RESULTS: We studied 344 patients with an average age of 21.7 years. Detection of C. trachomatis was positive in 7.9% women and it was not found in any of the patients studied for N. gonorrhoeae. 98% considered self-sampling instructions easy to understand, 87.5% felt comfortable taking the sample. CONCLUSIONS: Prevalence of C. trachomatis in the study population was similar to that described in other national and international studies. N. gonorrhoeae was not found in this series, which is consistent with literature reports. The self-sampling technique of vaginal sample was well accepted by the patients. However, they were anxious about the quality of the sample. According to our results, it is important to emphasize the importance of annual detection of these pathogens and that self-sampling technique is a valid alternative.
