RESUMEN

Given the proven benefits of screening to reduce diabetic ketoacidosis (DKA) likelihood at the time of stage 3 type 1 diabetes diagnosis, and emerging availability of therapy to delay disease progression, type 1 diabetes screening programmes are being increasingly emphasised. Once broadly implemented, screening initiatives will identify significant numbers of islet autoantibody-positive (IAb+) children and adults who are at risk of (confirmed single IAb+) or living with (multiple IAb+) early-stage (stage 1 and stage 2) type 1 diabetes. These individuals will need monitoring for disease progression; much of this care will happen in non-specialised settings. To inform this monitoring, JDRF in conjunction with international experts and societies developed consensus guidance. Broad advice from this guidance includes the following: (1) partnerships should be fostered between endocrinologists and primary-care providers to care for people who are IAb+; (2) when people who are IAb+ are initially identified there is a need for confirmation using a second sample; (3) single IAb+ individuals are at lower risk of progression than multiple IAb+ individuals; (4) individuals with early-stage type 1 diabetes should have periodic medical monitoring, including regular assessments of glucose levels, regular education about symptoms of diabetes and DKA, and psychosocial support; (5) interested people with stage 2 type 1 diabetes should be offered trial participation or approved therapies; and (6) all health professionals involved in monitoring and care of individuals with type 1 diabetes have a responsibility to provide education. The guidance also emphasises significant unmet needs for further research on early-stage type 1 diabetes to increase the rigour of future recommendations and inform clinical care.

RESUMEN

AIMS: To find clinical and immunological signatures of the SARS-CoV-2 and the COVID-19 pandemic on children newly diagnosed with type 1 diabetes (T1D). METHODS: A single-centre, retrospective, observational study comparing the clinical and immunological characteristics of children diagnosed with T1D the year before and during the first 2 years of the COVID-19 pandemic. Data extracted from the medical records included clinical and demographic parameters, COVID-19 PCR results and the presence of anti-islet, thyroid and celiac-related antibodies. Also obtained from the medical records was a family history of T1D, celiac disease and autoimmune thyroid disease in a first-degree family member. RESULTS: A total of 376 children were diagnosed with T1D during the study period. A total of 132 in the pre-COVID era and 246 in the first 2 years of the pandemic. At diagnosis, the pH in children with DKA was lower, and HbA1c tended to be higher in the COVID-19 group compared to the pre-COVID-19 group (7.30 [7.18, 7.35] vs 7.33 [7.19, 7.36], p = 0.046) and (110.9 [86.9, 129.5] vs 100 [80.3, 129.5], p = 0.067]) respectively. Multiple islet antibodies (IA) were significantly more common among patients in the pre-COVID-19 group compared to the COVID-19 group (72% vs 61%, p = 0.032). Tissue transglutaminase antibodies were more common among children diagnosed in the COVID-19 compared to the pre-COVID group (16.6% vs 7.9%, p = 0.022). CONCLUSIONS: Our findings suggest that SARS-CoV-2 and the environmental alterations caused by the pandemic affected the clinical characteristics and the immunological profile of children diagnosed with T1D. It is, therefore, plausible that the virus plays a role in the autoimmune process causing T1D.

RESUMEN

BACKGROUND: Gonadotropin-releasing hormone analog (GnRHa) is the standard treatment for children with central precocious puberty (CPP). We assessed efficacy and safety of GnRHa treatment in girls with CPP and early fast puberty (EFP). METHODS: This retrospective observational study included anthropometric, clinical and laboratory data retrieved from medical files of girls with CPP or EFP, treated with GnRHa and followed at a tertiary endocrine clinic during 2007-2021. RESULTS: For both CPP (n = 144) and EFP (n = 231) groups, mean height-SDS at GnRHa initiation and termination and at the last follow-up visit was greater than mid-parental height-SDS (P < 0.001). Only among girls with EFP, mean BMI-SDS was higher at treatment termination than initiation (P = 0.025). Median ages at menarche of the CPP and EFP groups were 11.8 and 12.0 years. Menstrual irregularities were reported in 20.3% of girls with CPP and in 18.7% of those with EFP. Adverse effects to treatment were reported in 3.5% and 3.9% of girls with CPP and EFP, respectively. CONCLUSIONS: In this large cohort, GnRHa treatment in girls with EFP was effective without significant adverse effects as in those with CPP. A randomized controlled trial is required to examine the psychological impact of GnRHa treatment of variant early puberty. IMPACT STATEMENT: Gonadotropin-releasing hormone analog (GnRHa) is the standard treatment for central precocious puberty (CPP). We assessed efficacy and safety of GnRHa treatment in girls with early fast puberty (EFP), characterized by pubertal signs between ages 8-9 years with fast pubertal signs advancement and accelerated growth and bone maturation and in girls with CPP. We found in this large cohort that GnRHa treatment in girls with EFP was effective and safe as in those with CPP. A prospective randomized controlled trial is required to examine the psychological impact of GnRHa treatment of variant early puberty.

RESUMEN

Objective: The aim of this study was to assess the extent of nondisclosure of type 1 diabetes in adolescents and investigate its association with several psychosocial parameters and clinical outcomes. Research design and methods: This was a cross-sectional study based on data collected from 69 adolescents with type 1 diabetes who were 12-18 years of age and followed at our diabetes clinic. The degree of disclosure, demographics, diabetes management, and psychosocial issues were assessed via questionnaires. Clinical parameters were derived from medical records. Associations between nondisclosure status and clinical and psychosocial study variables were assessed. Results: Fifty-three participants (77%) reported some extent of nondisclosure. Nondisclosure was associated with low self-esteem, reduced friend support, and increased diabetes-related worries. Nondisclosure was also found to be associated with diminished self-care behaviors related to insulin administration and with elevated A1C. Conclusion: Our results demonstrate that nondisclosure of type 1 diabetes in adolescents may be more common than initially recognized and is likely associated with unfavorable psychological outcomes and reduced self-care and diabetes management. Our results emphasize the importance of social interactions and disclosure in adolescents and may serve as a potential stepping stone to address other social barriers hindering diabetes management.

RESUMEN

AIMS: To assess the prevalence and disease-related risk factors for disordered eating behaviours among adolescents with type 1 diabetes and also to search for risk factors at disease diagnosis that can predict the development of disordered eating behaviours. METHODS: A retrospective observational study of 291 adolescents aged 15-19 years with type 1 diabetes who completed the Diabetes Eating Problem Survey-Revised (DEPS-R) as is routine in our diabetes clinic. The prevalence of disordered eating behaviours and risk factors for their development was assessed. RESULTS: In 84 (28.9%) adolescents, disordered eating behaviours were found. Disordered eating behaviours were positively associated with female sex (ß = 3.01 [SE = 0.97], p = 0.002), higher BMI-Z score (ß = 2.08 [SE = 0.49], p < 0.001), higher HbA1c (ß = 0.19 [SE = 0.03], p < 0.001) and treatment with multiple daily injections of insulin (ß = 2.19 [SE = 1.02], p = 0.032). At type 1 diabetes diagnosis, higher BMI-Z score (ß = 1.54 [SE = 0.63], p = 0.016) for those diagnosed before age 13 years and increased weight gain at 3 months post-diagnosis (ß = 0.88 [SE = 0.25], p = 0.001) in females diagnosed at age 13 years or older were found to be risk factors for disordered eating behaviours. CONCLUSIONS: Disordered eating behaviours are common among adolescents with type 1 diabetes and are associated with various parameters, including BMI at diagnosis and the rate of weight gain at 3 months post-diagnosis in females. Our findings highlight the need for early preventive efforts for disordered eating behaviours and interventions to avoid late diabetes complications.

RESUMEN

AIMS: Study aims: (1) developing and validating a novel questionnaire for measuring fear of hyperglycaemia among parents of children with type 1 diabetes (T1D) - the Hyperglycaemia Fear Survey - Parent version (FoHyper-P); (2) investigating correlations between parental fear of hyperglycaemia and objective measures of glycaemic control. METHODS: A multi-centre, multinational study of 152 parents of children with T1D was conducted in three large diabetes clinics from Israel, Poland, and Greece. Inclusion criteria were parents of children aged 6-16 years, at least 6 months from diagnosis, at least 3 months of CGM use and parental involvement in care. Parents filled the FoHyper-P and the Hypoglycaemia Fear Survey - Parent Version (HFS-P). Patient data were obtained via electronic medical records and informative questionnaires. Bonferroni correction was performed to counteract multiple comparisons. RESULTS: Significant strong-moderate correlations were found between FoHyper-P and HFS-P including total questionnaires scoring (r = 0.747, pBonf < 0.001), worries subscales (r = 0.735, pBonf <0.001), and behaviour subscales (r = 0.532, pBonf <0.001). Using linear regression models, we found a positive association between the worry subscale and HbA1C. Weak correlations (p < 0.05, not significant after Bonferroni correction) were found between time in range, time above range and parental fear of hyperglycaemia as well as between worry subscales and a higher HbA1C in the past year, percent of hyperglycaemia and lower TIR. CONCLUSIONS: The FoHyper-P is a novel, validated tool for assessing parental fear of hyperglycaemia. Integrating it into clinical practice addresses an underestimated aspect of parental diabetes management, enabling better care for children with T1D.

RESUMEN

BACKGROUND: Optic pathway gliomas (OPGs) are classified by anatomic location and the association with neurofibromatosis type 1 (NF1). Children with OPGs face sequelae related to tumor location and treatment modalities. We assessed the prevalence of endocrine dysfunction in children with OPGs and compared outcomes between those with and without NF1. METHODS: We performed a retrospective medical record review of medical history, and clinical and laboratory data, of children diagnosed with OPGs (n = 59, 61% with NF1) during 1990-2020, followed at a tertiary endocrine clinic. Growth and puberty parameters and occurrence of endocrine dysfunction were evaluated. RESULTS: Isolated optic nerve involvement was higher among patients with than without NF1. Patients without NF1 were younger at OPG diagnosis and more often treated with debulking surgery or chemotherapy. At the last endocrine evaluation, patients without NF1 had comparable height SDS, higher BMI SDS, and a higher rate of endocrine complications (78.3% vs. 41.7%, p = 0.006). Younger age at diagnosis, older age at last evaluation, and certain OPG locations were associated with increased endocrine disorder incidence. CONCLUSIONS: Endocrine dysfunction was more common in patients without NF1; this may be related to younger age at presentation, tumor locations, a greater progressive rate, and more aggressive treatments. IMPACT: The literature is sparse regarding sporadic OPGs, and the mean duration of follow-up is shorter than at our study. Our data show a higher rate of endocrine dysfunction in patients with OPGs than previously described. We also found a higher prevalence of endocrine dysfunctions among patients without compared to those with NF-1. A better understanding of the true prevalence of endocrine disabilities that may evolve along time can help in guiding physicians in the surveillance needed in patients with OPG.

RESUMEN

This study investigated modifications to the ubiquitin proteasome system (UPS) in a mouse model of type 2 diabetes mellitus (T2DM) and their relationship to heart complications. db/db mice heart tissues were compared with WT mice tissues using RNA sequencing, qRT-PCR, and protein analysis to identify cardiac UPS modifications associated with diabetes. The findings unveiled a distinctive gene profile in the hearts of db/db mice with decreased levels of nppb mRNA and increased levels of Myh7, indicating potential cardiac dysfunction. The mRNA levels of USP18 (deubiquitinating enzyme), PSMB8, and PSMB9 (proteasome ß-subunits) were down-regulated in db/db mice, while the mRNA levels of RNF167 (E3 ligase) were increased. Corresponding LMP2 and LMP7 proteins were down-regulated in db/db mice, and RNF167 was elevated in Adult diabetic mice. The reduced expression of LMP2 and LMP7, along with increased RNF167 expression, may contribute to the future cardiac deterioration commonly observed in diabetes. This study enhances our understanding of UPS imbalances in the hearts of diabetic mice and raises questions about the interplay between the UPS and other cellular processes, such as autophagy. Further exploration in this area could provide valuable insights into the mechanisms underlying diabetic heart complications and potential therapeutic targets.

RESUMEN

BACKGROUND: Management of type 1 diabetes is challenging. We compared outcomes using a commercially available hybrid closed-loop system versus a new investigational system with features potentially useful for adolescents and young adults with type 1 diabetes. METHODS: In this multinational, randomised, crossover trial (Fuzzy Logic Automated Insulin Regulation [FLAIR]), individuals aged 14-29 years old, with a clinical diagnosis of type 1 diabetes with a duration of at least 1 year, using either an insulin pump or multiple daily insulin injections, and glycated haemoglobin (HbA1c) levels of 7·0-11·0% (53-97 mmol/mol) were recruited from seven academic-based endocrinology practices, four in the USA, and one each in Germany, Israel, and Slovenia. After a run-in period to teach participants how to use the study pump and continuous glucose monitor, participants were randomly assigned (1:1) using a computer-generated sequence, with a permuted block design (block sizes of two and four), stratified by baseline HbA1c and use of a personal MiniMed 670G system (Medtronic) at enrolment, to either use of a MiniMed 670G hybrid closed-loop system (670G) or the investigational advanced hybrid closed-loop system (Medtronic) for the first 12-week period, and then participants were crossed over with no washout period, to the other group for use for another 12 weeks. Masking was not possible due to the nature of the systems used. The coprimary outcomes, measured with continuous glucose monitoring, were proportion of time that glucose levels were above 180 mg/dL (>10·0 mmol/L) during 0600 h to 2359 h (ie, daytime), tested for superiority, and proportion of time that glucose levels were below 54 mg/dL (<3·0 mmol/L) calculated over a full 24-h period, tested for non-inferiority (non-inferiority margin 2%). Analysis was by intention to treat. Safety was assessed in all participants randomly assigned to treatment. This trial is registered with ClinicalTrials.gov, NCT03040414, and is now complete. FINDINGS: Between June 3 and Aug 22, 2019, 113 individuals were enrolled into the trial. Mean age was 19 years (SD 4) and 70 (62%) of 113 participants were female. Mean proportion of time with daytime glucose levels above 180 mg/dL (>10·0 mmol/L) was 42% (SD 13) at baseline, 37% (9) during use of the 670G system, and 34% (9) during use of the advanced hybrid closed-loop system (mean difference [advanced hybrid closed-loop system minus 670G system] -3·00% [95% CI -3·97 to -2·04]; p<0·0001). Mean 24-h proportion of time with glucose levels below 54 mg/dL (<3·0 mmol/L) was 0·46% (SD 0·42) at baseline, 0·50% (0·35) during use of the 670G system, and 0·46% (0·33) during use of the advanced hybrid closed-loop system (mean difference [advanced hybrid closed-loop system minus 670G system] -0·06% [95% CI -0·11 to -0·02]; p<0·0001 for non-inferiority). One severe hypoglycaemic event occurred in the advanced hybrid closed-loop system group, determined to be unrelated to study treatment, and none occurred in the 670G group. INTERPRETATION: Hyperglycaemia was reduced without increasing hypoglycaemia in adolescents and young adults with type 1 diabetes using the investigational advanced hybrid closed-loop system compared with the commercially available MiniMed 670G system. Testing an advanced hybrid closed-loop system in populations that are underserved due to socioeconomic factors and testing during pregnancy and in individuals with impaired awareness of hypoglycaemia would advance the effective use of this technology FUNDING: National Institute of Diabetes and Digestive and Kidney Diseases.

RESUMEN

BACKGROUND: The current coronavirus disease 2019 (COVID-19) pandemic has health, social, and economic implications. Our primary objective was to evaluate changes in body mass index (BMI) from the pre-pandemic to COVID-19 pandemic period among a large pediatric population in Israel. METHODS: This retrospective cohort study is based on data from Clalit Health Services, the largest health maintenance organization in Israel. The data accessed included sociodemographic, anthropometric, and clinical parameters of persons aged 2-20 years with at least one BMI measurement during 2017-2019 (pre-pandemic period) and one between April 1, 2020 and December 31, 2020 (pandemic period). RESULTS: The cohort comprised 36,837 individuals (50.8% females); median age 11.2 years, 83.6% were Jewish and 10.3% of Arab ethnicity. BMI-SDS increased in both sexes (p < 0.001), in both ethnicities (p < 0.001), in all socioeconomic position clusters (p < 0.001), in children aged 2-18 years (P < 0.001), and in children with underweight or normal-weight in the pre-pandemic period (p < 0.001). For 21,610 individuals (35.6%), BMI-SDS increased ≥0.25 SD. The increase in BMI-SDS was greater in children aged 2-6 compared to 6.1-18 years; BMI-SDS decreased among those aged 18.1-20 years (P < 0.001). The increase in BMI-SDS was greater among those with underweight than normal weight; BMI-SDS decreased among those with overweight and obesity (P < 0.001). During the pandemic, overweight or obesity presented in 11.2% of those with normal weight in the pre-pandemic period; and obesity presented in 21.4% of those with overweight in the pre-pandemic period. CONCLUSIONS: The COVID-19 pandemic correlated with overall weight gain among children and adolescents, with the most substantial weight gain in children aged 2-6 years. Notably, the most significant increase in BMI-SDS was observed in children with underweight; BMI-SDS decreased in children with overweight and obesity. Policies should be established during the pandemic that focus on increasing physical activity, reducing sedentary time, and promoting healthy diets.

RESUMEN

BACKGROUND: The objective of this study was to describe the differences in metabolic parameters and in time to recovery from diabetes ketoacidosis (DKA), between children and adolescents with newly diagnosed diabetes compared with established type 1 diabetes (T1DM). METHODS: This was a single-center, retrospective study. The cohort consists of 356 children and adolescents with T1DM who had DKA during 2008-2018. Data were obtained from the patients' medical files. Recovery of DKA was defined as the resolution of acidosis (pH >7.3 and bicarbonate >15 meq/L). RESULTS: The mean time to recovery from DKA was significantly longer in patients with newly diagnosed diabetes than in those with established diabetes (13± versus 8.5± h) (p < 0.001). This difference was maintained in an analysis according to DKA severity: mild, moderate, and severe. pH at presentation did not differ between the groups, but bicarbonate at presentation was significantly lower in patients with newly diagnosed diabetes than in those with established diabetes, 9.9± versus 12± mmol/L (p < 0.001). Potassium and phosphorus levels were lower, and sodium and chloride levels were higher in patients with newly diagnosed diabetes than in those with established diabetes (p < 0.001). CONCLUSIONS: DKA is associated with a shorter recovery time in patients with established diabetes compared to newly diagnosed diabetes. This may have implications on the treatment of people with established diabetes. IMPACT: DKA is associated with a shorter recovery time in patients with established diabetes compared with newly diagnosed diabetes. Shorter recovery time in a patient with established diabetes compared with newly diagnosed diabetes was observed in any DKA severity. The time to recovery from DKA did not differ significantly between patients treated with an insulin pump and those treated with multiple daily injections. Triggers for DKA among patients with established diabetes were poor compliance with treatment, infection, pump dysfunction, and dehydration.

RESUMEN

OBJECTIVES: Neonatal diabetes mellitus (NDM) is a rare form of monogenic diabetes, diagnosed before age 6 months. We aimed to describe the clinical characteristics, molecular genetics, and long-term follow-up of NDM patients from a single pediatric endocrine center in Israel. METHODS: Retrospective study (1975-2020) of all patients diagnosed with diabetes before 6 months of age, who tested negative for pancreatic autoantibodies. Medical records were reviewed for demographic, familial and medical history, and clinical and biochemical features; a genetic analysis was performed. RESULTS: Of 24 patients, nine had transient neonatal diabetes (TNDM) and 15 permanent neonatal diabetes (PNDM), of whom five had rare syndromic causes. Genetic etiology was revealed in 87.5% of the NDM cohort, and the most common causes were ABCC8 mutations in TNDM and KCNJ11 and insulin gene mutations in PNDM. The switch from insulin to off-label sulfonylurea therapy was successful for 5/9 (56%) of the qualifying candidates. Severe hypoglycemia and diabetic ketoacidosis developed in 2 (8%) patients, and chronic diabetes complications in 5 (21%) patients with more than 10 years NDM. At last follow-up, weight and height of all but two syndromic PNDM patients were normal. The median height-SDS of the TNDM subgroup was significantly taller and the mean weight-SDS significantly heavier than those of the PNDM subgroup (-0.52 (-0.67, -0.09) vs. -0.9 (-1.42, -0.3) (p = 0.035) and 0.22 ± 0.69 vs. -0.89 ± 1.21 (p = 0.02), respectively). PNDM patients showed no incremental change in mean weight SDS over the time. CONCLUSION: The Israeli NDM cohort has clinical and genetic characteristics comparable with other populations. Patients with TNDM were taller and heavier than those diagnosed with PNDM, although both show rapid catch-up growth and reached normal growth parameters. Chronic diabetes complications developed in patients with long-standing NDM.

RESUMEN

BACKGROUND: Prevalence of youth-onset type 2 diabetes (T2D) has increased worldwide, paralleling the rise in pediatric obesity. Occurrence and clinical manifestations vary regionally and demographically. OBJECTIVES: We assessed the incidence, and clinical and demographic manifestations of youth-onset T2D in Israel. METHODS: In a national observational study, demographic, clinical, and laboratory data were collected from the medical records of children and adolescents, aged 10-18 years, diagnosed with T2D between the years 2008 and 2019. RESULTS: The incidence of youth-onset T2D in Israel increased significantly from 0.63/100,000 in 2008 to 3.41/100,000 in 2019. The study cohort comprised 379 individuals (228 girls [59.7%], 221 Jews [58.3%], mean age 14.7 ± 1.9 years); 73.1% had a positive family history of T2D. Mean body mass index (BMI) z-score was 1.96 ± 0.7, higher in Jews than Arabs. High systolic (≥ 130 mmHg) and diastolic blood pressure (≥ 85 mmHg) were observed in 33.7% and 7.8% of patients, respectively; mean glycosylated hemoglobin (A1c) level at diagnosis was 8.8 ± 2.5%. Dyslipidemia, with high triglyceride (>150 mg/dl) and low HDL-c (<40 mg/dl) levels, was found in 45.6% and 56.5%, respectively. Microalbuminuria and retinopathy were documented at diagnosis, 15.2% and 1.9%, respectively) and increased (36.7% and 4.6%, respectively) at follow-up of 2.9 ± 2.1 years. Criteria of metabolic syndrome were met by 224 (62.2%) patients, and fatty liver documented in 65%, mainly Jews. Psychosocial comorbidity was found in 31%. Treatment with metformin (45.6%), insulin (20.6%), and lifestyle modification (18%) improved glycemic control. CONCLUSION: Youth-onset T2D in Israel has increased significantly and presents a unique profile.

RESUMEN

OBJECTIVE: To evaluate the incidence and severity of ketoacidosis (DKA) at type 1 diabetes diagnosis during the first wave of the coronavirus disease 2019 (COVID-19) pandemic in Israel. RESEARCH DESIGN AND METHODS: A population-based study the product of a national collaboration of Israeli pediatric diabetes centers investigated the presentation of childhood-onset type 1 diabetes. The frequencies of DKA and severe DKA observed during the COVID-19 period from March 15, 2020 (commencement of the first nationwide lockdown) until June 30, 2020 were compared with the same periods in 2019, 2018, and 2017 using multivariable logistic regression, adjusting for age, sex, and socioeconomic position. RESULTS: During the COVID-19 period, DKA incidence was 58.2%, significantly higher than in 2019 (adjusted OR [aOR] 2.18 [95% CI, 1.31-3.60], P = 0.003); 2018 (aOR 2.05 [95% CI, 1.26-3.34], P = 0.004); and 2017 (aOR, 1.79 [95% CI, 1.09-2.93], P = 0.022). The incidence of severe DKA was 19.9%, significantly higher than in 2018 (aOR, 2.49 [95% CI, 1.20-5.19], P = 0.015) and 2017 (aOR, 2.73 [95% CI, 1.28-5.82], P = 0.009). In 2020, admissions and duration of stay in the intensive care unit were higher than in previous years (P = 0.001). During the COVID-19 pandemic, children aged 6-11 years had higher incidences of DKA (61.3% vs. 34.0%, 40.6%, and 45.1%, respectively, P = 0.012), and severe DKA (29.3% vs. 15.1%, 10.9%, and 5.9%, respectively, P = 0.002). CONCLUSIONS: The dramatic increase in DKA at presentation of childhood-onset type 1 diabetes during the COVID-19 pandemic mandates targeted measures to raise public and physician awareness.

RESUMEN

OBJECTIVE: Given the large number of false-positive growth hormone deficiency (GHD) diagnoses from a single growth hormone (GH) stimulation test in children, 2 different pharmacologic tests, performed on separate days or sequentially, are required. This study aimed to assess the reliability and safety of a combined arginine-clonidine stimulation test (CACST). METHODS: This was a retrospective, single-center, observational study. During 2017-2019, 515 children aged >8 years underwent GH stimulation tests (CACST: n = 362 or clonidine stimulation test [CST]: n = 153). The main outcome measures used to compare the tests were GH response (sufficiency/deficiency) and amplitude and timing of peak GH and safety parameters. RESULTS: Population characteristics were as follows: median age of 12.2 years (interquartile range [IQR]: 10.7, 13.4), 331 boys (64%), and 282 prepubertal children (54.8%). The GHD rate was comparable with 12.7% for CACST and 14.4% for CST followed by a confirmatory test (glucagon or arginine) (P = .609). Peak GH was higher and occurred later in response to CACST compared with CST (14.6 ng/mL [IQR: 10.6, 19.4] vs 11.4 ng/mL [IQR: 7.0, 15.8], respectively, P < .001; 90 minutes [IQR: 60, 90] vs 60 minutes [IQR: 60, 90], respectively, P < .001). No serious adverse events occurred following CACST. CONCLUSION: Our findings demonstrate the reliability and safety of CACST in detecting GHD in late childhood and adolescence, suggesting that it may replace separate or sequential GH stimulation tests. By diminishing the need for the second GH stimulation test, CACST saves time, is more cost-effective, and reduces discomfort for children, caregivers, and medical staff.

RESUMEN

OBJECTIVE: To compare clinical outcomes of 3 treatment regimens-glucocorticoids (GCs), oral contraceptives (OCs), or a combination of both-administered to adolescents and young women diagnosed in childhood with nonclassical congenital adrenal hyperplasia (NCCAH), who had been treated with GCs until their adult height was achieved. METHODS: A retrospective study of medical records of 53 female patients with NCCAH followed in 3 tertiary pediatric endocrinology institutes. The 3 treatment groups were compared for the prevalence of hirsutism and acne, standardized body mass index (BMI)-standard deviation score (SDS), and androgen levels at the attainment of adult height (baseline), 1-year later, and at the last documented visit. RESULTS: At baseline, there were no significant differences among groups in BMI-SDS, androgen levels, hirsutism prevalence, acne, or irregular menses. From baseline to the last visit, the rate of hirsutism declined significantly only in the OC group (37.5% vs 6.2%, respectively; P = .03). The rate of acne declined in the combined group (50% vs 9%, respectively; P = .03) with a similar tendency in the OC group (50% vs 12.5%, respectively; P = .05). No significant changes were observed in BMI-SDS for the entire cohort or any subgroup during follow-up. A significant rise in androstenedione (P < .001), testosterone (P < .01), and 17-hydroxyprogesterone (P < .01) levels was observed only in the OC group. CONCLUSION: In girls diagnosed in childhood with NCCAH, who require treatment for hyperandrogenism following completion of linear growth, management should be tailored individually using a patient-centered approach. Treatment with OCs might be better than that with GCs for regression of hirsutism and acne. The long-term effects of elevated levels of androgens associated with this treatment regimen should be further studied.

RESUMEN

AIM: To evaluate the effect of nutritional supplementation on height, weight and body composition in short and lean male preadolescents. METHODS: A randomised, double-blinded, placebo-controlled trial of nutritional supplementation of short and lean prepubertal 10-14.5-year-old boys. Primary outcomes included Δheight-SDS and Δweight-SDS. Secondary outcomes included changes in body composition and BMI-SDS. RESULTS: Of 160 boys enrolled, 126 (80%) completed 6 months' intervention. Baseline age, height-SDS, weight-SDS, BMI-SDS, body composition and dietary intake were similar in the formula and placebo groups. 'Good' formula consumers (intake of ≥50% of the recommended dose, n = 30) gained significantly more in weight-SDS, BMI-SDS, fat-free-mass and muscle mass (p < 0.05) than did 'poor' consumers (n = 35) and the placebo group (n = 61). Only in the formula group, positive dose-response correlations were found between consumption of the formula and changes in the outcome parameters examined, including Δheight-SDS (r = 0.301, p = 0.015). Boys aged >11.4 years who were 'good' formula consumers maintained their Δheight-SDS, while Δheight-SDS declined in 'poor' consumers and the placebo group of the same age (p = 0.033). CONCLUSION: Intervention with a multi-nutrient, protein-rich formula was effective in increasing weight-SDS, fat-free-mass, muscle mass and BMI-SDS in short and lean prepubertal male adolescents. Good consumption of the formula prevented Δheight-SDS decline in the older participants.

RESUMEN

AIM: To evaluate the efficacy and safety of ultra rapid lispro (URLi) versus lispro (Humalog® ) in people with type 1 diabetes on continuous subcutaneous insulin infusion (CSII). MATERIALS AND METHODS: This was a phase 3, 16-week, treat-to-target study in patients randomized to double-blind URLi (N = 215) or lispro (N = 217). The primary endpoint was change from baseline HbA1c (non-inferiority margin 4.4 mmol/mol [0.4%]), with multiplicity-adjusted objectives for postprandial glucose (PPG) levels during a meal test, and time spent in the target range 70-180 mg/dL (TIR). RESULTS: URLi was non-inferior to lispro for change in HbA1c, with a least-squares mean (LSM) difference of 0.3 mmol/mol (95% confidence interval [CI] -0.6, 1.2) or 0.02% (95% CI -0.06, 0.11). URLi was superior to lispro in controlling 1- and 2-h PPG levels after the meal test: LSM difference -1.34 mmol/L (95% CI -2.00, -0.68) or -24.1 mg/dL (95% CI -36.0, -12.2) at 1 h and -1.54 mmol/L (95% CI -2.37, -0.72) or -27.8 mg/dL (95% CI -42.6, -13.0) at 2 h; both p < .001. TIR and time in hyperglycaemia were similar between groups but URLi resulted in significantly less time in hypoglycaemia (<3.0 mmol/L [54 mg/dL]) over the daytime, night-time and 24-h period: LSM difference -0.41%, -0.97% and -0.52%, respectively, all p < .05. The incidence of treatment-emergent adverse events was higher with URLi (60.5% vs. 44.7%), driven by infusion-site reaction and infusion-site pain, which was mostly mild or moderate. Rates of severe hypoglycaemia and diabetic ketoacidosis were similar between groups. CONCLUSIONS: URLi was efficacious, providing superior PPG control and less time in hypoglycaemia but with more frequent infusion-site reactions compared with lispro when administered by CSII.

RESUMEN

AIM: To investigate the effect of the sodium-glucose co-transporter-2 inhibitor dapagliflozin on glucose levels overnight and during the following day after two unannounced meals under full closed loop (FCL) conditions. MATERIALS AND METHODS: For this single-centre, double-blind, randomized, placebo-controlled, cross-over trial, non-obese persons with type 1 diabetes (T1D) were studied twice (10 mg dapagliflozin bid vs. placebo) for 24 hours with two unannounced mixed meal tests 6 hours apart under FCL conditions. Primary outcome was sensor glucose time in range (TIR; 3.9-10 mmol/L). For safety evaluation, ß-hydroxybutyrate (BHB), glucagon, insulin and gastric inhibitory polypeptide were measured. RESULTS: Fifteen adolescents (aged 15.4 ± 1.6 years, diabetes duration 10.0 ± 3.4 years, HbA1c 8.4% ± 0.9% [67.7 ± 10.1 mmol/mol]) and 15 young adults (aged 18.7 ± 0.8 years; diabetes duration 12.5 ± 3.6 years; HbA1c 8.3% ± 0.9% [68.5 ± 11.2 mmol/mol]) completed the trial. TIR was significantly higher in the intervention group compared with placebo (68% ± 6% vs. 50% ± 13%; P < .001); nocturnal glucose was significantly lower with dapagliflozin (6.2 ± 0.7 vs. 7.3 ± 1.7 mmol/L; P = .003) without an increase in time at less than 3.9 mmol/L (3.3% ± 6.0% vs 3.1% ± 5.2%; P = .75). Urinary glucose excretion was increased 3-fold using dapagliflozin (149 ± 42 vs. 49 ± 23 g/24 hours) with a total insulin reduction of 22% (39.7 ± 12.7 vs. 30.6 ± 10.4 U; P = .004). No abnormal elevated BHB values were observed. CONCLUSIONS: In adolescents and adults with T1D, dapagliflozin significantly increased TIR on average by 259 minutes/day while reducing glycaemic variability during FCL control without any signs of hypoglycaemia or ketosis.

RESUMEN

AIM: To evaluate the efficacy and safety of adjunct dapagliflozin therapy in patients with type 1 diabetes (T1D). MATERIALS AND METHODS: DEPICT-1 and -2 were randomized, double-blind, parallel-group, 24-week studies, with 28-week extension periods. Adults with T1D and HbA1c 7.5%-10.5% were randomized (1:1:1) to receive dapagliflozin 5 mg, 10 mg or placebo. The short- and long-term efficacy and safety of dapagliflozin were examined in an exploratory pooled analysis of both studies. RESULTS: Efficacy analyses included 530, 529 and 532 and safety analysis included 548, 566 and 532 patients in the dapagliflozin 5 mg, 10 mg and placebo groups, respectively. Baseline characteristics were similar between treatment groups. At week 24, reductions were seen with dapagliflozin 5 and 10 mg compared with placebo in HbA1c (-0.40%, -0.43% vs. 0.00%) and body weight (-2.45, -2.91 vs. 0.11 kg). HbA1c and body weight reductions versus placebo were also seen after 52 weeks of treatment. There was no imbalance in occurrence of severe hypoglycaemic events between groups. The proportion of patients experiencing definite diabetic ketoacidosis (DKA) was higher with dapagliflozin 5 mg (4.0%) and 10 mg (3.5%) compared with placebo (1.1%) over 52 weeks; most events were of mild or moderate severity, and all resolved with treatment. CONCLUSIONS: Over 52 weeks, dapagliflozin provided glycaemic and weight benefits, with no increased frequency of severe hypoglycaemia compared with placebo. More DKA events were reported with dapagliflozin than placebo, highlighting the importance of appropriate patient selection, education and risk-mitigation strategies.
