Objective: To compare bone accrual in PHIV and healthy children.

Longitudinal changes in mitochondrial-associated measures and insulin resistance in youth with perinatally-acquired HIV in the U.S.

HIV infection and its treatment are associated with mitochondrial dysfunction and metabolic derangement. However, longitudinal changes in oxidative phosphorylation activities [Complex I (C1) and Complex IV (C4)], or venous lactate/pyruvate ratios (LPR), and their relationships with insulin resistance (IR), remain unclear in youth living with perinatally-acquired HIV (YPHIV). We measured venous LPR, C1, and C4 activities in blood cells and homeostatic model assessment for IR (HOMA-IR) over two years.

Long-Acting Gonadotropin-Releasing Hormone Analogues for Central Precocious Puberty, Including 45-Mg 6-Month Subcutaneous Leuprolide Acetate: Use for Treatment and Treatment Monitoring.

Introduction: Studies of gonadotropin-releasing hormone analogues (intramuscular [IM] leuprolide acetate [LA] and triptorelin) for treatment monitoring of central precocious puberty (CPP) demonstrate this approach is effective for confirming pubertal hormone suppression. Herein, we provide new data using subcutaneous LA (SC LA), suggesting similar efficacy for treatment monitoring.

Methods: PubMed, Embase, and CINAHL were searched for studies of GnRHa used to monitor treatment of CPP.

Gut permeability is associated with lower insulin sensitivity in youth with perinatally acquired HIV.

The relationships between alterations in the intestinal barrier, and bacterial translocation with the development of metabolic complications in youth with perinatally acquired HIV (YPHIV) have not been investigated. The PHACS Adolescent Master Protocol enrolled YPHIV across 15 U.S.

Lower Insulin Sensitivity Through 36 Months of Life With in Utero HIV and Antiretroviral Exposure in Botswana: Results From the Tshilo Dikotla Study.

Background: There are little data on changes in insulin sensitivity during the first few years of life following in utero human immunodeficiency virus (HIV) and antiretroviral (ARV) exposure.

Methods: The Tshilo Dikotla study enrolled pregnant persons with HIV (PWH) (receiving tenofovir/emtricitabine or lamivudine plus dolutegravir or efavirenz) and pregnant individuals without HIV, as well as their liveborn children. Newborns were randomized to receive either zidovudine (AZT) or nevirapine (NVP) postnatal prophylaxis.

An overview of growth hormone therapy in pediatric cases documented in the Kabi International Growth Study (Pfizer International Growth Database).

The Kabi International Growth Study (KIGS) was first established in 1987 and is the largest pharmaco-epidemiological study of recombinant human growth hormone (rhGH). KIGS is aimed at evaluating long-term safety and treatment outcomes in pediatric subjects who received Genotropin rhGH therapy (Pfizer, New York, NY, USA) as prescribed by physicians in real-world clinical practice settings. KIGS data have been used to answer multiple research questions related to growth, growth prediction, and growth hormone treatment, leading to the publication of 129 peer-reviewed manuscripts and 24 biannual reports, outcomes from 10 expert meetings, and 3 books.

Neural Correlates of Obesity and Inflammation in Children and Adolescents with Congenital Adrenal Hyperplasia.

Introduction: Patients with classical congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency exhibit an increased prevalence of obesity from childhood including central adiposity and inflammation. There is also an emerging affected brain phenotype in CAH, with decreased cortico-limbic gray matter volumes and white matter abnormalities. We aimed to study the relationship between brain structure, obesity, and inflammation in children and adolescents with CAH compared to controls.

Insights from an advisory board: Facilitating transition of care into adulthood in brain cancer survivors with acquired pediatric growth hormone deficiency.

Objective: Children with growth hormone deficiency (GHD) face multiple challenges that can negatively impact the transition from pediatric to adult endocrinology care. For children with GHD resulting from brain cancer or its treatment, the involvement of oncology care providers and possible disease-related comorbidities add further complexity to this transition.

Design: An advisory board of pediatric and adult endocrinologists was convened to help better understand the unique challenges faced by childhood cancer survivors with GHD, and discuss recommendations to optimize continuity of care as these patients proceed to adulthood.

Multi-stakeholder opinion statement on the care of individuals born with differences of sex development: common ground and opportunities for improvement.

Background: In the last 15 years, the care provided for individuals born with differences of sex development (DSD) has evolved, with a strong emphasis on interdisciplinary approaches. However, these developments have not convinced some stakeholders to embrace the current model of care. This care model has also paid insufficient attention to socio-cultural differences and global inequalities.

Puberty Today, Gone Tomorrow: Transient Refractory Central Precocious Puberty in a Toddler with End-Stage Kidney Disease.

Unlabelled: Novel Insights: - There are only three reported cases of precocious puberty in boys with CKD - Hypothalamic dysfunction due to uremia, and disordered renal clearance of LH, may lead to central precocious puberty, which resolves after uremia is corrected, e.g., after kidney transplant.

Practice Variation among Pediatric Endocrinologists in the Dosing of Glucocorticoids in Young Children with Congenital Adrenal Hyperplasia.

A Pediatric Endocrine Society (PES) Drugs and Therapeutics Committee workgroup sought to determine the prescribing practices of pediatric endocrinologists when treating children <10 years of age with congenital adrenal hyperplasia (CAH). Our workgroup administered a 32-question online survey to PES members. There were 187 respondents (88.

Longitudinal changes in body fat and metabolic complications in young people with perinatally acquired HIV.

Background: The role of body fat on metabolic complications remains poorly understood in young people living with perinatally acquired HIV (YPHIV).

Objective: Our objective was to assess the association of changes in adiposity over 2 years with metabolic outcomes in YPHIV.

Methods: The PHACS Adolescent Master Protocol (AMP) study enrolled YPHIV from 2007 to 2009 across 15 US sites, including Puerto Rico.

Differences in Hyperandrogenism Related to Early Detection of Non-Classical Congenital Adrenal Hyperplasia on Second Newborn Screen.

Screening for congenital adrenal hyperplasia (CAH) remains heterogenous across geographies-we sought to determine the proportion of non-classical CAH (NCAH) detection by one vs. two newborn screens (NBS) in two U.S.

Impact of youth onset type 2 diabetes during pregnancy on microvascular and cardiac outcomes.

Aims: To examine the impact of pregnancy on microvascular and cardiovascular measures in women with youth-onset T2D.

Methods: Microvascular and cardiovascular measures were compared in in a cohort of 116 women who experienced a pregnancy of ≥ 20 weeks gestation and 291 women who did not among women in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study.

Patient and Parent Perspectives on Testicular Adrenal Rest Tumors in Congenital Adrenal Hyperplasia.

Background: Testicular adrenal rest tumors (TARTs) increase the risk of infertility in males with classic congenital adrenal hyperplasia (CAH). There is no consensus regarding at what age screening testicular ultrasounds should begin and how often they should be repeated. Furthermore, it is unknown whether patients and parents are aware of the significance of TARTs.

Electrolyte abnormalities and stress dosing predict illness-related hospitalizations among infants and toddlers with congenital adrenal hyperplasia.

Objective: Infants and toddlers with classical congenital adrenal hyperplasia (CAH) are at high risk for morbidity/mortality arising from life-threatening adrenal crisis. Management of acute illnesses in CAH requires an understanding of factors leading to emergency department (ED) visits and hospitalizations in the first few years of life. We, therefore, examined adrenal crisis at prehospital and ED stages of illness in young children with CAH as they related to medical outcomes.
