RESUMEN

Context: Adolescents and young women (AYA) with type 1 diabetes (T1D) may require hormonal contraception for an extended period. However, it is unclear what effect hormonal contraception has on telomere length, a marker of the risk for complications. Objective: To investigate the relative telomere length (RTL) in AYA with T1D (AYA-T1D) and healthy young women (AYA-C) after 18 months of combined oral contraception use (COC) with ethinyl estradiol/desogestrel, or a subdermal etonogestrel implant (IM). Methods: A nonrandomized prospective study was performed in which 39 AYA-T1D and 40 AYA-C chose the COC or the IM. RTL was measured by monochrome multiplex-quantitative PCR in DNA from peripheral blood mononuclear cells (PBMC). The impact of contraceptives and clinical variables on RTL was assessed using lineal regression analysis. Results: Longer RTL compared to baseline was observed in AYA-T1D (P < .05) and AYA-C (P  < .01) after using the IM. However, the total of AYA and the AYA-C group treated with COC decreased RTL after 18 months of treatment compared to baseline (P < .05). The type of contraceptive used was determinant for the changes in RTL compared to baseline in all subjects and controls (P ≤ .006). For AYA-T1D, HbA1c levels were not associated with RTL, but the high-sensitivity C-reactive protein was negatively related with the changes in RTL at 18 months compared to baseline (standardized R2 : 0.230, P  = .003). Conclusion: IM was associated with longer RTL in AYA-T1D and AYA-C. In contrast, a shortening of telomere length in PBMC was observed after using COC.

RESUMEN

STUDY OBJECTIVE: To determine the metabolic effects of the subcutaneous etonogestrel implant compared with an oral contraceptive in adolescents and young adults (AYAs) with type 1 diabetes (T1D) on body weight, body composition, glucose, lipids, and C-reactive protein levels. METHODS: This was a non-randomized, interventional, prospective study. Thirty-nine AYAs with T1D participated; 20 used the implant (Implant-T1D), and 19 used an oral combined contraceptive (OC-T1D). Body composition, HbA1c, intermittent continuous glucose monitoring, lipids, and high-sensitivity C-reactive protein (hsCRP) levels were evaluated. RESULTS: All participants were followed for at least 12 months, and 26 completed the 24-month follow-up. No women discontinued the intervention due to adverse effects. Body weight increased by 0.8 ± 3.5 and 1 ± 2.9 kg in the OC-T1D and the Implant-T1D group at 12 months and by 2.6 ± 3.9 and 3.3 ± 3.6 kg at 24 months, respectively. OC-T1D and Implant-T1D had similar HbA1c, mean interstitial glucose levels, and time in range throughout the study; no significant difference over time was observed. hsCRP levels increased in both groups and were associated with BMI and HbA1c (P < .001 for both variables). Women in the OC-T1D group had higher total cholesterol, HDL-C, and triglyceride levels compared with the Implant-T1D. CONCLUSION: Glucose levels were similar in youth using the subdermal progestin implant and an OC. However, both AYA groups showed increased BMI, fat mass, and subclinical inflammation. Changes in lipid levels were associated with the OC method. These data highlight the importance of weight gain prevention in young women with T1D using hormonal contraception.

RESUMEN

Polycystic ovary syndrome (PCOS) is one of the most common endocrine conditions in women. PCOS may be more challenging to diagnose during adolescence due to an overlap with the physiological events of puberty, which are part of the diagnostic criteria in adult women. This review focuses on the evidence available in relation to PCOS diagnostic criteria for adolescents. Adolescent PCOS should be diagnosed using two main criteria irregular -menstrual cycles (relative to number of years post-menarche) and hyperandrogenism (clinical and/or biochemical); after excluding other conditions that mimic PCOS. Accurate definitions of the two main criteria will decrease challenges/controversies with the diagnosis and provide timely diagnosis during adolescence to establish early management. Despite the attempts to create accurate diagnostic criteria and definitions, this review highlights the limited research in this area, especially in the follow up of adolescents presenting with one diagnostic feature that are called "at risk of PCOS". Studies in adolescents continue to use the Rotterdam diagnostic criteria that uses pelvic ultrasound. This is inappropriate, because previous and emerging data that show many healthy adolescents have polycystic ovarian morphology in the early years post-menarche. In the future, anti-Müllerian hormone levels might help support PCOS diagnosis if adolescents meet two main criteria.

RESUMEN

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.

RESUMEN

CONTEXT: First-degree relatives of women with polycystic ovary syndrome (PCOS) present hormonal and metabolic alterations compared to girls unrelated to PCOS. It is unknown whether glucose intolerance in the PCOS proband confers a more severe metabolic predisposition on their first-degree relatives. OBJECTIVE: To determine whether glucose tolerance status in women with PCOS is associated with worsened glucose metabolism and sex hormone levels in their peripubertal daughters or sisters. DESIGN: Cross-sectional study. SETTING: Seven academic centers in North America, South America, and Europe. PATIENTS: Sixty-four pairs of women with PCOS and their daughters or younger sisters aged between 8 and 14 years were recruited. Twenty-five mothers or older sisters with PCOS were glucose intolerant (GI) and 39 were normal glucose tolerant (NGT). MAIN OUTCOME MEASURES: Beta-cell function estimated by the insulin secretion-sensitivity index-2 (ISSI-2) during an oral glucose tolerance test and by the disposition index during a frequently sampled IV glucose tolerance test. Free testosterone and 17-hydroxyprogesterone (17-OHP) levels. RESULTS: Being related to a GI PCOS proband was associated with a lower ISSI-2 (P-value = 0.032) after adjusting for ethnicity, body mass index z-score, and pubertal stage. They also had higher free testosterone (P-value = 0.011) and 17-OHP levels compared to girls with an NGT proband, the latter becoming significant after adjusting for confounders (P-value = 0.040). CONCLUSIONS: Compared to first-degree female relatives of women with PCOS and NGT, first-degree relatives of women with PCOS and GI display lower beta-cell function and hyperandrogenemia, putting them at higher risk of GI and PCOS development.

RESUMEN

The presence of unprotected sex activity in women living with type 1 diabetes (T1D) who have insufficient glycemic control should be considered as a specific risky behavior. To evaluate risky behaviors, including unprotected sexual activity, sources of information and knowledge related to reproductive health in adolescents and young adult women with T1D (PwT1D) compared to a group of adolescents and young adult women without diabetes (Comparison group). PwT1D and the Comparison group completed a questionnaire with validated measures that assessed reproductive health. PwT1D (n = 115, age = 17.7 ± 3.2 years) and Comparison group (n = 386, age = 18.3 ± 2.9) were recruited. The proportion of women reporting having sex without any contraceptive was similar in both groups (57.1% and 50%, in PwT1D and Comparison group, respectively). The use of non-effective contraceptive was reported in 63.2% and 63.6% of the PwT1D and Comparison group, respectively. Among PwT1D, parents, formal sex education, and friends were the primary source of information on reproductive health. Low levels of knowledge about diabetes and pregnancy were observed in PwT1D. HbA1c level was associated with having at least one sexual activity without any contraception (OR = 1.63, p = 0.039). PwT1D have similar rates of risky behaviors compared to a Comparison group. Sexual risky behaviors should be especially considered in PwT1D with glycemic control above the optimal level. Parents are an important source of reproductive health information for PwT1D. Use of effective contraception should be reinforced in sexually active PwT1D.

RESUMEN

The International Society for Pediatric and Adolescent Diabetes Clinical Practice Consensus Guideline 2018 for management of diabetic ketoacidosis (DKA) and the hyperglycemic hyperosmolar state provide comprehensive guidance for management of DKA in young people. Intravenous (IV) infusion of insulin remains the treatment of choice for treating DKA; however, the policy of many hospitals around the world requires admission to an intensive care unit (ICU) for IV insulin infusion. During the coronavirus 2019 (COVID-19) pandemic or other settings where intensive care resources are limited, ICU services may need to be prioritized or may not be appropriate due to risk of transmission of infection to young people with type 1 or type 2 diabetes. The aim of this guideline, which should be used in conjunction with the ISPAD 2018 guidelines, is to ensure that young individuals with DKA receive management according to best evidence in the context of limited ICU resources. Specifically, this guideline summarizes evidence for the role of subcutaneous insulin in treatment of uncomplicated mild to moderate DKA in young people and may be implemented if administration of IV insulin is not an option.

RESUMEN

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.

RESUMEN

Diabetic ketoacidosis (DKA) is the most common acute hyperglycaemic emergency in people with diabetes mellitus. A diagnosis of DKA is confirmed when all of the three criteria are present - 'D', either elevated blood glucose levels or a family history of diabetes mellitus; 'K', the presence of high urinary or blood ketoacids; and 'A', a high anion gap metabolic acidosis. Early diagnosis and management are paramount to improve patient outcomes. The mainstays of treatment include restoration of circulating volume, insulin therapy, electrolyte replacement and treatment of any underlying precipitating event. Without optimal treatment, DKA remains a condition with appreciable, although largely preventable, morbidity and mortality. In this Primer, we discuss the epidemiology, pathogenesis, risk factors and diagnosis of DKA and provide practical recommendations for the management of DKA in adults and children.

RESUMEN

Reproductive dysfunction is a common but little studied complication of diabetes. The spectrum of reproductive health problems in diabetes is broad, and encompasses delayed puberty and menarche, menstrual cycle abnormalities, subfertility, adverse pregnancy outcomes, and potentially early menopause. Depending on the age at diagnosis of diabetes, reproductive problems can manifest early on in puberty, emerge later when fertility is desired, or occur during the climacteric period. Historically, women with type 1 diabetes have frequently had amenorrhoea and infertility, due to central hypogonadism. With the intensification of insulin therapy and improved metabolic control, these problems have declined, but do persist. Additional reproductive implications of contemporary diabetes management are now emerging, including polycystic ovary syndrome and hyperandrogenism, which are underpinned by insulin action on the ovary. The sharp rise in type 2 diabetes incidence in youth suggests that more women of reproductive age will encounter diabetes-related reproductive problems in their lifetimes. With an ever increasing number of young women living with diabetes, clinicians need to be aware of and equipped for the challenges of navigating reproductive health concerns across the lifespan.

RESUMEN

OBJECTIVE: To study the reproductive and metabolic differences between daughters of women with polycystic ovary syndrome (PCOSd) and control women (Cd) after menarche. DESIGN: Case-control study. SETTING: Clinical endocrinology unit. PATIENT(S): We studied 43 PCOSd and 28 Cd 1.5-6 years after menarche. INTERVENTION(S): Determination of anthropometry, pubertal development, hirsutism, oral glucose tolerance test, and GnRH analogue test. MAIN OUTCOME MEASURE(S): Ferriman score, sex steroids, gonadotropins, antimüllerian hormone (AMH), ovarian volumes, and glucose and insulin levels. RESULT(S): The groups were similar in chronologic, gynecologic, and menarchal ages and anthropometric variables. Ferriman score, ovarian volumes, and AMH were higher in PCOSd. Propensity score analysis showed that there were significant differences in LH, LH-FSH ratio, T and free androgen index, post-stimulated LH and LH-FSH ratio, and 2-hour insulin that could be attributed only to the fact of being a PCOS daughter. The generalized linear model showed that higher LH levels were positively associated with AMH and T levels. CONCLUSION(S): We found that higher LH, androgen, and insulin levels are present in PCOSd during the postmenarchal period, which may establish the basis for the development of PCOS during adulthood. Moreover, LH levels were associated with AMH levels, which supports that the neuroendocrine feedback proposed for AMH and LH is present in humans and that this feature is probably programed in utero, as recently shown in mice.
