Muscle-to-fat ratio in children and adolescents with type 1 diabetes in predicting glycaemic control and partial clinical remission.

BACKGROUND: Advances in treatment could mitigate the expected adverse changes in the body composition of children and adolescents with type 1 diabetes (T1D). OBJECTIVES: To examine the evolution of weight status and body composition and their association with glycaemic control and partial clinical remission in youth with T1D. METHODS: Ninety-nine participants with T1D (median age 9.5 years [interquartile range 7.3, 12.9], 59.6% boys) were longitudinally followed for 3 years since diagnosis. Data at seven pre-determined time points were extracted from medical files. Outcome measures included body mass index (BMI) z-scores, muscle-to-fat ratio (MFR) z-scores, haemoglobin A1c (HbA1c) levels, continuous glucose monitoring metrics, and insulin dose-adjusted HbA1c (IDAA1c) levels. RESULTS: The BMI z-scores increased significantly (p < 0.001) for both sexes, with no significant change in MFR z-scores over time. The girls had higher BMI z-scores (p < 0.001) and lower MFR z-scores than the boys (p = 0.016). The mean HbA1c levels decreased during the first month and at 3 months since diagnosis (p < 0.001), then plateaued and achieved a median overall HbA1c of 7.1% for the entire cohort. At 12 months, 37 participants (37.6%) were in partial clinical remission, as evidenced by IDAA1c ≤ 9. The odds of partial clinical remission at 2 years increased by 2.1-fold for each standard deviation increase in the MFR z-score (p < 0.001). Higher MFR z-scores were associated with better metabolic control. CONCLUSIONS: Integration of body composition assessments could mitigate adverse body changes in paediatric patients with T1D.

Sex differences in body composition in youth with type 1 diabetes and its predictive value in cardiovascular disease risk assessment.

BACKGROUND: Women with type 1 diabetes (T1D) are more susceptible than men to cardiovascular disease (CVD). Signs of increased risk may already appear among adolescent girls. OBJECTIVES: We explored the contribution of body composition to the development of CVD risk factors among youth with T1D. METHODS: One hundred and eighty nine subjects with T1D (mean age 15.3 ± 5.1 years, 55% boys) followed between January 2018-January 2022 were included in this observational study. Sociodemographic and clinical data were extracted from medical files. Body composition was measured by bioelectrical impedance analysis, and muscle-to-fat ratio (MFR) z-scores were calculated. Logistic regression model assessed the association between body composition (MFR z-scores) and evidence of CVD risk factors. RESULTS: Females were characterised by higher median BMI z-scores (0.47 vs. 0.04, p = 0.012), higher fat and truncal fat percentage levels (p ≤ 0.001) and lower median MFR z-scores (-0.64 vs. -0.25, p ≤ 0.001), higher median triglyceride (TG) levels (71 vs. 61 mg/dl, p = 0.05), longer disease duration to initiation of insulin pump therapy (p = 0.041), and more time spent in marked hypoglycemia (1 vs. 0.2%, p = 0.007) than males. Males' MFR z-scores were associated with several diabetes-related parameters (age at diagnosis, CGM metrics, HbA1c and insulin dose), while the females'' MFR z-scores were linked to the atherogenic dyslipidemia index (TG:HDL ratio). The odds for CVD risk factors were doubled for every 1 SD decrease in MFR z-score (OR = 0.50, CI [0.30-0.84], p = 0.009) and also increased with age (OR = 1.07, CI [1.004-1.148], p = 0.038). CONCLUSIONS: Body composition measurement has a predictive value in CVD risk assessment in youth with T1D, with unique characteristics and influences in each sex.

Body composition in pediatric celiac disease and metabolic syndrome component risk-an observational study.

BACKGROUND: Celiac disease (CD) in children and adolescents has been linked with increased susceptibility for cardiometabolic disease in adulthood. We explored the interaction between body composition and metabolic syndrome (MetS) components in pediatric CD. METHODS: We conducted a retrospective observational study of patients with CD followed at our Pediatric Endocrine and Gastroenterology Units between 1/2018-1/2022. Data on sociodemographic, clinical, laboratory, and body composition parameters (bioelectrical impedance analysis, BIA) were collected. RESULTS: Forty-four patients with MetS components and 67 patients without them were enrolled. The cohort's mean age at BIA assessment was 11.5 ± 3.6 years. Individuals with MetS components were older (P = 0.045), had higher BMI z-scores (P < 0.001), higher total and truncal fat percentage levels (P < 0.001), lower muscle-to-fat ratio z-scores (P = 0.018), higher sarcopenic indices (P = 0.05), higher systolic blood pressure percentiles (P = 0.001), higher triglycerides levels (P = 0.009), and higher triglycerides/HDL-c ratios (P < 0.001) than those without MetS components. A sex- and age-adjusted model revealed that the diagnosis of MetS components was positively associated with fat percentage (odds ratio = 1.087, confidence interval [1.010-1.171], P = 0.027), but not with BMI z-scores (P = 0.138). CONCLUSIONS: We found that fat percentage but not weight status is associated with risk for MetS components in individuals with childhood-onset CD. Preventive interventions should target an improvement in body composition. IMPACT: The literature on cardiometabolic risk in pediatric patients with celiac disease (CD) is sparse. Our analysis revealed that at least one metabolic syndrome (MetS) component was present in two out of every five children and adolescents with CD. An increase in fat percentage but not in body mass index z-scores predicted the presence of MetS components in our cohort. These findings suggest that the weight status of children and adolescents with CD does not mirror their risk for MetS components. Body composition analysis should be considered as an integral part of the clinical evaluation in young patients with CD.

Linear growth of children with X-linked hypophosphatemia treated with burosumab: a real-life observational study.

To assess the long-term efficacy of burosumab for pediatric patients with X-linked hypophosphatemia, focusing on linear growth. This multi-center retrospective study included 35 pediatric patients who began treatment with burosumab between January 2018 and January 2021. We collected clinical data, anthropometric measurements, laboratory results, and Rickets Severity Score (RSS), from 2 years prior to treatment initiation and up to 4 years after. Burosumab was initiated at a mean age of 7.5 ± 4.4 years (range 0.6-15.9), with a mean initial dose of 0.8 ± 0.3 mg/kg, which was subsequently increased to 1.1 ± 0.4 mg/kg. The patients were followed for 2.9 ± 1.4 years (range 1-4) after initiating burosumab. Serum phosphorus levels increased from 2.7 ± 0.8 mg/dl at burosumab initiation to 3.4 ± 0.6 mg/dl after 3 months and remained stable (p < 0.001). Total reabsorption of phosphorus increased from 82.0 ± 6.8 to 90.1 ± 5.3% after 12 months of treatment (p = 0.041). The RSS improved from 1.7 ± 1.0 at burosumab initiation to 0.5 ± 0.6 and 0.3 ± 0.6 after 12 and 24 months, respectively (p < 0.001). Both height z-score and weight z-score improved from burosumab initiation to the end of the study: from - 2.07 ± 1.05 to - 1.72 ± 1.04 (p < 0.001) and from - 0.51 ± 1.12 to - 0.11 ± 1.29 (p < 0.001), respectively. Eight children received growth hormone combined with burosumab treatment. Height z-score improved among those who received growth hormone (from - 2.33 ± 1.12 to - 1.94 ± 1.24, p = 0.042) and among those who did not (from - 2.01 ± 1.01 to - 1.66 ± 1.01, p = 0.001). CONCLUSION:  Burosumab treatment in a real-life setting improved phosphate homeostasis and rickets severity and enhanced linear growth. WHAT IS KNOWN: • Compared to conventional therapy, burosumab treatment has been shown to increase serum phosphate levels and reduce the severity of rickets. • The effect of burosumab on growth is still being study. WHAT IS NEW: • Height z-score improved between the start of burosumab treatment and the end of the study (-2.07 ± 1.05 vs. -1.72 ± 1.04, p < 0.001). • Eight children received burosumab combined with growth hormone treatment without side effects during the concomitant treatments.

Youth-onset type 2 diabetes in Israel: A national cohort.

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.

Alarming increase in ketoacidosis in children and adolescents with newly diagnosed type 1 diabetes during the first wave of the COVID-19 pandemic in Israel.

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.

Association between age at type 1 diabetes diagnosis and metabolic outcome at young adulthood: a real-life observational study.

BACKGROUND: Younger age at diagnosis of type 1 diabetes (T1D) may affect the clinical course and outcome. We examined whether age at diagnosis was associated with glycemic control and metabolic outcome in young adulthood. METHODS: This observational study included 105 young adults with T1D (current mean age: 21.2 ± 3.0 years, mean age at diagnosis 12.0 ± 4.0 years) followed during 2012 to 2019. Data on HbA1c, glucose variability, continuous glucose monitoring (CGM) metrics, body mass index (BMI), blood pressure (BP), and body composition were collected from medical records from age 18 years until last visit, and the association between age at diagnosis and outcomes was assessed. RESULTS: Age at T1D diagnosis was negatively associated with HbA1c levels (r = -0.368, P = .001), BMI (r = -0.218, P = .026), and diastolic BP (r = -0.215, P = .028). Younger age at diagnosis predicted poorer glycemic control after controlling for T1D duration, sex, socioeconomic status, BMI, and CGM use (r2 = 0.19, P = .002). There was a 0.1% greater HbA1c reduction for every yearly increase in age at diagnosis (ß = -0.090, P = .042). The mean metabolic age of females diagnosed at <10 years of age was older than their chronological age (P = .049). CONCLUSIONS: Younger age at T1D diagnosis predicts worse glycemic control at young adulthood, independent of recognized confounding risk factors (disease duration, sex, socioeconomic status, weight, and use of diabetes technology). Female patients diagnosed at a young age have an older metabolic age, indicating the need for lifestyle alteration to improve their basal metabolic rate.

Nutritional Therapy in Children With Spinal Muscular Atrophy in the Era of Nusinersen.

OBJECTIVES: Spinal muscular atrophy (SMA) is a genetic motor neuron disorder characterized by progressive muscle atrophy. Our aims were to evaluate the impact of nutritional intervention and nusinersen therapy on the nutritional status of SMA patients. STUDY DESIGN: This prospective study included all children and young adults (<24 years of age) with SMA who attended our multidisciplinary SMA clinic, during January 2017-July 2019. We documented demographic, clinical, anthropometric, and nutritional data at baseline and follow-up. A nutritional intervention was implemented according to standards of the 2018 Consensus Statement of SMA Management. RESULTS: The cohort included 51 SMA patients with a median age of 7.2 (interquartile range 2.1-15.3) years. Among them, 24 (47%) were SMA type 1, 16 (31.4%) SMA type 2, and 11 (21.6%) SMA type 3 patients. At baseline, 28 (54.9%) patients presented with malnutrition, 20 (71.4%) of whom with severe malnutrition. A decline in the frequency of severe malnutrition of SMA type 1 patients was observed at follow-up. The body mass index of patients who started nusinersen therapy after the nutritional intervention increased significantly compared with patients that started nusinersen therapy before the nutritional intervention (P = 0.042). There was also a significant increase in total energy and protein consumption in the former group (P = 0.043). CONCLUSIONS: Malnutrition is frequent among children with SMA, and the nutritional status of patients that started nusinersen therapy after implementation of a nutritional intervention underwent a more significant improvement. The importance of combining adequate nutritional management with disease-modifying treatment is highlighted.

Beyond Body Mass Index - Body Composition Assessment by Bioimpedance in Routine Endocrine Practice.

OBJECTIVE: To explore the body composition of pediatric patients referred for endocrine evaluation. METHODS: This real-life observational study conducted between January 2018 and January 2020 included 10 001 clinic visits of 3500 children and adolescents; first visits of 5 to 18-year-old patients were included. Anthropometric data, blood pressure levels, pubertal status, and bioelectrical impedance analysis (BIA, Tanita MC-780 MA) were extracted from medical files. Excluded from the analysis were patients participating in other studies. RESULTS: A total of 1001 patients (48% boys, mean age 11.3 ± 3.4 years, 33.5% prepubertal) were included. Mean anthropometric z-scores were normal and similar for boys and girls. Sex differences in body composition were as follows: boys had lower fat percentage, lower truncal fat percentage, higher appendicular skeletal muscle mass, and a higher muscle-to-fat ratio (MFR) than girls (P < .001 for all). MFR correlated with body mass index-standard deviation scores (BMI-SDS) in overweight/obese patients (r = -0.558, P < .001), although not in underweight patients. Systolic blood pressure (SBP) correlated with BMI-SDS in overweight/obese patients (r = 0.262, P < .001), although not in underweight patients. Diastolic blood pressure (DBP) did not correlate with BMI-SDS in either group of extreme weight status. MFR correlated with SBP and DBP in overweight/obese patients (r = -0.230, P < .001 and r = -0.141, P = .018, respectively) as well as in underweight patients (r = 0.331, P < .001 and r = 0.264, P = .005, respectively). CONCLUSIONS: Our findings support BIA for a more refined characterization of patients referred for endocrine evaluation than BMI-SDS. MFR may be a better surrogate marker of blood pressure levels than BMI-SDS in both underweight and overweight/obese pediatric patients.

Cardiometabolic outcomes in children and adolescents with West syndrome.

BACKGROUND: West syndrome is a convulsive disorder of infancy with unique seizures and a characteristic background electroencephalograph pattern. Adrenocorticotropic hormone (ACTH) is effective in spasm cessation, yet metabolic consequences of this therapeutic agent in childhood have not been published. METHODS: In this observational study we explored the cardiometabolic outcomes of 117 children with West syndrome (78 ACTH-treated and 39 non-ACTH-treated) monitored at a single medical center from 1995 to 2019 (median follow-up 7.2 years). Outcomes included the prevalence of cardiometabolic derangements (obesity, hypertension, and dyslipidemia) during infancy (< 2 years), early childhood (2-6 years), and childhood/adolescence (6-18 years). RESULTS: The rates of metabolic derangements during infancy in the West syndrome cohort were high compared to childhood/adolescence (obesity 27.3 % vs. 3.3 %, [p = 0.010], diastolic hypertension 48.8 % vs. 5.1 % [p < 0.001], hypertriglyceridemia 71 % vs. 40 % [p = 0.008], low high-density lipoprotein cholesterol [HDL-c] 54.2 % vs. 12.9 % [p = 0.001], and elevated triglycerides/HDL-c ratios 62.5 % vs. 12.9 % [p < 0.001]). The proportion of systolic and/or diastolic blood pressure levels categorized as hypertensive was 58.5 % during infancy, 48.1 % during early childhood, and 26.3 % during childhood/adolescence. ACTH-treated patients had higher weight and weight-to-length z-scores and higher triglyceride levels during infancy compared to non-ACTH-treated patients (p = 0.008, p = 0.001, and p = 0.037, respectively), and higher triglyceride levels during early childhood (p = 0.050), with no significant group differences during childhood/adolescence. CONCLUSIONS: Children with West syndrome apparently have an increased prevalence of cardiometabolic derangements more pronounced in infants and in ACTH-treated patients. These findings highlight the need to monitor these children for cardiometabolic derangements, even though these cardiometabolic abnormalities are transitory and tend to decrease with time. The health implications of cardiometabolic derangements during critical windows of growth and development warrant further investigation.

The heritability of body composition.

BACKGROUND: Physical growth during childhood and adolescence is influenced by both genetic and environmental factors. Heritability, the proportion of phenotypic variance explained by genetic factors, has been demonstrated for stature and weight status. The aim of this study was to explore the heritability of body composition. METHODS: A real-life, observational study of the children and adolescents referred to the Endocrine Unit in a tertiary medical center. In January 2018, body composition by means of bioimpedance analysis (BIA) was implemented as part of the standard intake assessment of subjects referred for endocrine consultation. The clinic BIA database was searched for subjects with the term "observation of growth" as the sole reason for referral. BIA of 114 triads of healthy subjects aged 5-18 years and their parents were analyzed. The BIA report included the following data: fat mass, fat percentage, truncal fat percentage and muscle mass. Calculated variables included: appendicular skeletal muscle mass (ASMM = the sum of muscle mass of four limbs), muscle-to-fat ratio [MFR = ASMM (kg)/fat mass (kg)] and sarcopenic index [(SI = ASMM(kg)/height (meter)²]. Data collection from medical files included pubertal stage and home address for socioeconomic position grading. RESULTS: There were sex differences in body composition parameters in both the prepubertal and pubertal subjects. The boys among the prepubertal subjects had a lower fat percentage on average than girls (p = 0.020). Among the adolescents, boys on average had lower fat percentage (p = 0.011), higher sarcopenic index (p = 0.021), and higher muscle-to-fat ratio (p < 0.001), than adolescent girls. Correlation analyses between body composition parameters of all participants revealed significant correlations in the sarcopenic index of prepubertal children and their parents (boys-fathers: r = 0.380, p = 0.050; boys-mothers: r = 0.435, p = 0.026; girls-fathers: r = 0.462, p = 0.012; girls-mothers: r = 0.365, p = 0.050) and adiposity indices (fat percentage, truncal fat percentage and muscle-to-fat ratio) of prepubertal boys and their mothers (r = 0.438, p = 0.025; r = 0.420, p = 0.033, and r = 0.478, p = 0.014, respectively). There were no associations between body composition parameters of adolescents and their parents. Socioeconomic position adversely affected fat percentage in adolescent girls and mothers. CONCLUSIONS: Heritable body composition traits were demonstrated in childhood but not in adolescence, suggesting that environmental influence has a more telling effect during teenage years.

Paediatricians' practices and knowledge of corticosteroids: A national survey.

AIM: To explore corticosteroid prescription practices and knowledge among paediatricians. METHODS: The Paediatricians Corticosteroids Survey, a cross-sectional, web-based survey distributed to Israeli paediatricians between February and July 2018. RESULTS: Three hundred and forty-nine paediatricians (105 general paediatricians, 207 subspecialists and 37 paediatric endocrinologists) participated. Two hundred and three (58.2%) had >10 years of paediatric clinical experience and treated >60 patients/wk on average, 175/318 (55%) prescribed corticosteroids to >10% of their patients. On knowledge items, 11/266 (4.1%) responded 'not sure' when tapering of steroids is required, 22/268 (8.2%) to what 'stress dose' meant and 27/268 (10.1%) when a stress dose is required. Multivariate linear analysis showed higher scores were associated with training in paediatric endocrinology (ß = 2.271, P = 0.032); medical practice only in a subspecialty (ß = 1.909, P = 0.041) or in both general paediatrics and a subspecialty (ß = 2.023, P = 0.014), compared to general paediatrics alone and medical studies in Israel (ß = 1.059, P = 0.035). Overall, 96.2% thought continued medical education (CME) sessions would be helpful. CONCLUSION: Our findings suggest that despite clinical experience with corticosteroid usage, respondents demonstrated gaps in knowledge for potentially life-threatening situations. Corticosteroid-based CME programs are warranted to improve paediatricians' knowledge and patient management.

Incidental Findings on Brain Magnetic Resonance Imaging (MRI) in Pediatric Endocrine Patients.

OBJECTIVE: To explore incidental findings on brain magnetic resonance imaging (MRI) studies of pediatric patients referred due to endocrine disorders. METHODS: A retrospective, observational study conducted in a tertiary referral center. The neuroimaging database of 17,445 brain MRI studies of 11,011 pediatric patients were searched for cases with endocrine referrals and without medical history of malignancy, genetic syndromes, and/or neurologic comorbidities. This database was linked to the pediatric neurosurgical database. Clinical data were retrieved from medical files. RESULTS: In total, 524 patients (50.2% males, mean age 8.5±3.5 years) were referred to brain MRI due to growth disturbances (n = 313), pubertal disorders (n = 183), prolactin hypersecretion (n = 18), central diabetes insipidus (n = 8), and obesity (n = 1). Incidental findings were found in 128 (24.4%) cases. Chiari type 1 malformation was more prevalent in patients with growth disturbances (P<.001). Small pituitary cysts were observed in 20 (3.8%) patients, and pineal cysts in 25 (4.8%) patients, mostly girls (68%, P<.001). White matter lesions were diagnosed in 30 (5.7%) patients, none with clinical evidence of neurologic disease. Brain asymmetry without clinical significance and developmental venous anomalies were observed in 14 (2.7%) and 8 (1.5%) patients, respectively. Twelve patients were diagnosed with intracranial tumors, and 5 required surgical intervention for a histopathologic diagnosis of juvenile pilocytic astrocytoma (n = 3), choroid plexus papilloma (n = 1), or inconclusive (n = 1). The rest were managed conservatively. CONCLUSION: Incidental findings on brain MRIs of pediatric patients referred by endocrinologists are common and raise dilemmas. The spectrum ranges from structural disruptions to tumors. Decision-making is individualized and patient-centered.

HEALTH-RELATED QUALITY OF LIFE IN CHILDREN AND ADOLESCENTS WITH NONCLASSIC CONGENITAL ADRENAL HYPERPLASIA.

Objective: Nonclassic congenital adrenal hyperplasia (NCCAH) is a late-onset milder form of congenital adrenal hyperplasia that differs dramatically from the classic form. Health-related quality of life (HRQOL) in pediatric patients with the sole diagnosis of NCCAH has not been determined; therefore, in this study, we aimed to determine whether HRQOL is compromised in comparison to the general population. Methods: Single-center, cross-sectional, case-control study. Twenty-three hydrocortisone-treated children and adolescents (7 males) diagnosed with NCCAH by cosyntropin stimulation test and CYP21A2 gene mutation analysis were recruited to this study; 6 healthy siblings were also recruited. HRQOL was assessed by the child and parent-proxy PedsQL Inventory and compared between NCCAH subjects and healthy siblings. HRQOL scores of NCCAH subjects were compared with known standards from the U.S. and Israeli general healthy populations. Anthropometric measurements of children and parents were performed and compared between NCCAH subjects and healthy siblings. Pearson correlation coefficients were calculated. Results: HRQOL scores of the participants and parents did not differ between NCCAH subjects and healthy siblings. The HRQOL emotional domain scores of the NCCAH patients and parent were significantly lower than the healthy U.S. pediatric population (P = .046) but not different from established standards of the healthy Israeli population (P = .583). Anthropometric measurements were within the normal range and did not differ between NCCAH subjects and their siblings. Total, school functioning, and psychosocial HRQOL domain scores were positively correlated with body mass index-standard deviation score in NCCAH subjects. Conclusion: HRQOL was not adversely affected by NCCAH among adequately treated children and adolescents. Abbreviations: BMI = body mass index; CAH = congenital adrenal hyperplasia; HRQOL = health-related quality of life; NCCAH = nonclassic congenital adrenal hyperplasia; PedsQL = Pediatric Quality of Life Inventory; SDS = standard deviation score.

Sex, Ethnicity, and Socioeconomic Status Affect on Israeli Pediatric Lipid Testing Despite Equality in National Healthcare Services.

BACKGROUND: In Israel, coronary heart disease mortality rates are significantly higher among the Arab population than the Jewish population. Dyslipidemia prevention should begin in childhood. OBJECTIVES: To identify sociodemographic disparities in the preventive health measurement of lipid profile testing and lipoprotein levels among Israeli children and adolescents. METHODS: A cross-sectional analysis of 1.2 million children and adolescents insured by Clalit Health Services between 2007 and 2011 was conducted using sociodemographic data and serum lipid concentrations. RESULTS: Overall, 10.1% individuals had undergone lipid testing. Those with male sex (odds ratio [OR] = 0.813, 95% confidence interval [95%CI] 0.809-0.816), Arab ethnicity (OR = 0.952, 95%CI 0.941-0.963), and low socioeconomic status (SES) (OR = 0.740, 95%CI 0.728-0.752) were less likely to be tested. By 2010, differences among economic sectors narrowed and Arab children were more likely to be tested (OR = 1.039, 95%CI 1.035-1.044). Girls had higher total cholesterol, triglyceride, low-density lipoprotein-cholesterol, and non-high-density lipoprotein-cholesterol levels compared to boys (P < 0.001). Jewish children had higher cholesterol and low-density and high-density lipoprotein-cholesterol, as well as lower triglyceride levels than Arabs (P < 0.001). Children with low SES had lower cholesterol, low-density and high-density lipoprotein-cholesterol, and non-high-density lipoprotein-cholesterol levels (P < 0.001). CONCLUSIONS: We found that boys, Arab children, and those with low SES were less likely to be tested. Over time there was a gradual reduction in these disparities. Publicly sponsored healthcare services can diminish disparities in the provision of preventive health among diverse socioeconomic groups that comprise the national population.

A Phase II, Double-Blind, Randomized, Placebo-Controlled, Multicenter Study Evaluating the Efficacy and Safety of Alpha-1 Antitrypsin (AAT) (Glassia®) in the Treatment of Recent-Onset Type 1 Diabetes.

Our aim was to assess the efficacy, safety, and tolerability of alpha-1 antitrypsin (AAT) as a therapeutic modality for ß-cell preservation in patients with recent-onset type 1 diabetes. Seventy type 1 diabetes patients (37 males; mean age 13.1 ± 4.1years) were randomized to treatment with 22 infusions of AAT (Glassia®) (60 or 120 mg/kg) or placebo. The primary outcome was the area under the curve (AUC) of C-peptide from a 2-h mixed-meal tolerance test after 52 weeks. At week 52, C-peptide was 0.9, 0.45, and 0.48 pmol/mL in the AAT-120, AAT-60, and placebo groups (p = 0.170 and p = 0.866 vs. placebo, respectively). The declines in C-peptide glycated hemoglobin (HbA1c) and the total insulin dose (U/kg) were similar across groups. Within the predefined 12-18-years subgroup, the C-peptide AUC decreased significantly in the placebo and AAT-60 groups (-0.34 and -0.54 pmol/mL, respectively, p < 0.01), with a borderline decrease in the AAT-120 group (-0.29 pmol/mL, p = 0.047). The mean HbA1c level was significantly lower in the AAT-120 group compared to the placebo (6.7% ± 0.9% vs. 8.2 ± 1.4%, p = 0.05), and a higher percentage of patients attained HbA1c ≤ 7% (75% vs. 25%, p = 0.05). AAT was tolerated well, with a similar safety profile between groups. The AAT intervention showed promise in the subgroup of adolescents with recent-onset type 1 diabetes. Further studies are warranted to determine the impact and proposed mechanism of action of AAT in ß-cell preservation.

Adjusting insulin doses in patients with type 1 diabetes who use insulin pump and continuous glucose monitoring: Variations among countries and physicians.

AIMS: To evaluate physicians' adjustments of insulin pump settings based on continuous glucose monitoring (CGM) for patients with type 1 diabetes and to compare these to automated insulin dose adjustments. METHODS: A total of 26 physicians from 16 centres in Europe, Israel and South America participated in the study. All were asked to adjust insulin dosing based on insulin pump, CGM and glucometer downloads of 15 patients (mean age 16.2 ± 4.3 years, six female, mean glycated haemoglobin 8.3 ± 0.9% [66.8 ± 7.3 mmol/mol]) gathered over a 3-week period. Recommendations were compared for the relative changes in the basal, carbohydrate to insulin ratio (CR) and correction factor (CF) plans among physicians and among centres and also between the physicians and an automated algorithm, the Advisor Pro (DreaMed Diabetes Ltd, Petah Tikva, Israel). Study endpoints were the percentage of comparison points for which there was full agreement on the trend of insulin dose adjustments (same trend), partial agreement (increase/decrease vs no change) and full disagreement (opposite trend). RESULTS: The percentages for full agreement between physicians on the trend of insulin adjustments of the basal, CR and CF plans were 41 ± 9%, 45 ± 11% and 45.5 ± 13%, and for complete disagreement they were 12 ± 7%, 9.5 ± 7% and 10 ± 8%, respectively. Significantly similar results were found between the physicians and the automated algorithm. The algorithm magnitude of insulin dose change was at least equal to or less than that proposed by the physicians. CONCLUSIONS: Physicians provide different insulin dose recommendations based on the same datasets. The automated advice of the Advisor Pro did not differ significantly from the advice given by the physicians in the direction or magnitude of the insulin dosing.

The Effect of National Service on Metabolic Control, Weight Status and Incidence of Acute Diabetes Complications in Young Adults with Type 1 Diabetes.

BACKGROUND: Patients with type 1 diabetes (T1D) are exempt from conscript military service, but some volunteer for national service. OBJECTIVES: To evaluate the effect of national service (military or civil) on metabolic control and incidence of acute diabetes complications in young adults with T1D. METHODS: Clinical and laboratory data of 145 T1D patients were retrieved from medical records. The cohort comprised 76 patients volunteering for national service and 69 non-volunteers. Outcome measures were HbA1c, body mass index-standard deviation scores (BMI-SDS), insulin dosage, and occurrence of severe hypoglycemia or diabetic ketoacidosis (DKA). RESULTS: Metabolic control was similar in volunteers and non-volunteers: mean HbA1c at various time points was: 7.83 ± 1.52% vs. 8.07% ± 1.63 one year before enlistment age, 7.89 ± 1.36% vs. 7.93 ± 1.42% at enlistment age, 7.81 ± 1.28% vs. 8.00 ± 1.22% one year thereafter, 7.68 ± 0.88% vs. 7.82 ± 1.33% two years thereafter, and 7.62 ± 0.80% vs. 7.79 ± 1.19% three years thereafter. There were no significant changes in HbA1c from baseline throughout follow-up. BMI and insulin requirements were similar and remained unchanged in volunteers and controls: mean BMI-SDS one year before enlistment age was 0.23 ± 0.83 vs. 0.29 ± 0.95, at enlistment age 0.19 ± 0.87 vs. 0.25 ± 0.98, one year thereafter 0.25 ± 0.82 vs. 0.20 ± 0.96, two years thereafter 0.10 ± 0.86 vs. 0.15 ± 0.94, and three years thereafter 0.20 ± 0.87 vs. 0.16 ± 0.96. Mean insulin dose in U/kg/day one year before enlistment age was 0.90 ± 0.23 vs. 0.90 ± 0.37, at enlistment age 0.90 ± 0.28 vs. 0.93 ± 0.33, one year thereafter 0.86 ± 0.24 vs. 0.95 ± 0.33, two years thereafter 0.86 ± 0.21 vs. 0.86 ± 0.29, and three years thereafter 0.87 ± 0.23 vs. 0.86 ± 0.28. There were no episodes of severe hypoglycemia or DKA in either group. CONCLUSIONS: Our data indicate that during voluntary national service young adults with T1D maintain metabolic control similar to that of non-volunteers.

Cytokine profile of food-allergic post-liver transplant children is identified by high levels of IL-5 and low IL-10 secretion from patients' peripheral blood mononuclear cells.

Severe allergic reaction to food following liver transplantation is a well-known phenomenon. However, the mechanisms underlying this phenomenon are not yet elucidated. This study aimed to reveal the nature of the immune response in post-transplanted allergic patients and compare them to non-allergic transplanted as well as allergic and non-allergic control subjects, with focus on cytokine milieu. Post-liver transplant patients with and without allergic reactions as well as food-allergic but otherwise healthy and healthy non-allergic control patients were recruited. We reviewed patient records and routine laboratory tests and assayed subjects' PBMCs, studying cytokine secretion profile in response to different stimuli. Post-transplant patients with food allergy showed a unique cytokine profile in response to various stimuli, with extremely elevated IL-5, low IL-10 secretion, and somewhat higher IFN-γ. T regulatory cell number was not significantly different among the groups of patients and controls. Immune response of food-allergic post-liver transplant patients is identified by a unique cytokine profile when compared to allergic but otherwise healthy individuals.

Cardiovascular health in pediatric patients with X-linked hypophosphatemia under two years of burosumab therapy.

Introduction: X-linked hypophosphatemia (XLH) is caused by an inactivating mutation in the phosphate-regulating endopeptidase X-linked (PHEX) gene whose defective product fails to control phosphatonin fibroblast growth factor 23 (FGF23) serum levels. Although elevated FGF23 levels have been linked with detrimental cardiac effects, the cardiologic outcomes in XLH patients have been subject to debate. Our study aimed to evaluate the prevalence and severity of cardiovascular morbidity in pediatric XLH patients before, during, and after a 2-year treatment period with burosumab, a recombinant anti-FGF23 antibody. Methods: This prospective observational study was conducted in a tertiary medical center, and included 13 individuals with XLH (age range 0.6-16.2 years) who received burosumab every 2 weeks. Clinical assessment at treatment initiation and after .5, 1, and 2 years of uninterrupted treatment included anthropometric measurements and cardiologic evaluations (blood pressure [BP], electrocardiogram, conventional echocardiography, and myocardial strain imaging). Results: The linear growth of all patients improved significantly (mean height z-score: from -1.70 ± 0.80 to -0.96 ± 1.08, P=0.03). Other favorable effects were decline in overweight/obesity rates (from 46.2% to 23.1%) and decreased rates of elevated BP (systolic BP from 38.5% to 15.4%; diastolic BP from 38.5% to 23.1%). Electrocardiograms revealed no significant abnormality throughout the study period. Cardiac dimensions and myocardial strain parameters were within the normative range for age at baseline and remained unchanged during the study period. Conclusion: Cardiologic evaluations provided reassurance that 2 years of burosumab therapy did not cause cardiac morbidity. The beneficial effect of this treatment was a reduction in cardiovascular risk factors, as evidenced by the lower prevalence of both overweight/obesity and elevated BP.
