Abstract
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.

Abstract
Background and Aims: Disordered eating behaviors (DEB) are more common among individuals with type 1 diabetes (T1D) compared to those without, and for insulin pump users may be associated with higher hemoglobin A1c (HbA1c). We investigated DEB risk factors among insulin pump-treated individuals with T1D and clinical characteristics of hybrid closed-loop (HCL) systems' users by DEB level. Methods: An observational, cross-sectional study of 167 insulin pump-treated individuals with T1D, 13-21 years of age. Data were obtained from patients' medical charts with additional self-reported questionnaires, including assessment of DEB. Results: DEB were found in 71 (42.5%) individuals, and positively associated with female sex (β = 2.98 [standard error (SE) = 1.31], P = 0.025), body mass index (BMI)-Z-score (β = 2.12 [SE = 0.64], P = 0.001), HbA1c (β = 1.40 [SE = 0.45], P = 0.02), and higher rate of pump discontinuation (β = 4.48 [SE = 1.99], P = 0.026). The use of HCL systems compared to insulin pumps was associated with higher BMI-Z-score (odds ratio [OR]: 3.46 [95% confidence interval, CI: 1.52-7.87], P = 0.003) and tendency to lower HbA1c level (OR: 0.44 [95% CI: 0.18-1.09], P = 0.078) among individuals without DEB, and with lower HbA1c level (OR: 0.29 [95% CI: 0.10-0.83], P = 0.022) and higher socioeconomic status (OR: 1.73 [95% CI: 1.09-2.74], P = 0.020) among individuals with DEB. Conclusions: DEB are common among individuals with T1D treated with insulin pumps and are associated with higher HbA1c levels. Among T1D individuals with DEB, HCL system use is associated with lower HbA1c compared to insulin pump treatment. Our findings highlight the importance of regular screening for DEB and its risk factors to improve pump treatment and diabetes management. Moreover, individuals with DEB using HCL systems may benefit from reduced HbA1c levels.

Abstract
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.

Children with idiopathic short stature have significantly different gut microbiota than their normal height siblings: a case-control study. Front Endocrinol (Lausanne) 2024; 15:1343337.

Abstract
Objectives To investigate the role of gut microbiota (GM) in pathogenesis of idiopathic short stature (ISS) by comparing GM of ISS children to their normal-height siblings. Methods This case-control study, conducted at the Schneider Children's Medical Center's Institute for Endocrinology and Diabetes between 4/2018-11/2020, involved 30 pairs of healthy pre-pubertal siblings aged 3-10 years, each comprising one sibling with ISS and one with normal height. Outcome measures from fecal analysis of both siblings included GM composition analyzed by 16S rRNA sequencing, fecal metabolomics, and monitoring the growth of germ-free (GF) mice after fecal transplantation. Results Fecal analysis of ISS children identified higher predicted levels of genes encoding enzymes for pyrimidine, purine, flavin, coenzyme B, and thiamine biosynthesis, lower levels of several amino acids, and a significantly higher prevalence of the phylum Euryarchaeota compared to their normal-height siblings (p<0.001). ISS children with higher levels of Methanobrevibacter, the dominant species in the archaeal gut community, were significantly shorter in stature than those with lower levels (p=0.022). Mice receiving fecal transplants from ISS children did not experience stunted growth, probably due to the eradication of Methanobrevibacter caused by exposure to oxygen during fecal collection. Discussion Our findings suggest that different characteristics in the GM may explain variations in linear growth. The varying levels of Methanobrevibacter demonstrated within the ISS group reflect the multifactorial nature of ISS and the potential ability of the GM to partially explain growth variations. The targeting of specific microbiota could provide personalized therapies to improve growth in children with ISS.

Abstract
INTRODUCTION Diagnosing hypoglycemia in infants and children presents significant challenges. Our objective was to elucidate the diagnoses and clinical features of children with hypoglycemia referred to a pediatric endocrine tertiary clinic. METHODS Retrospective study of 154 children (0-18 years old) presenting with hypoglycemia, during 1992-2018. RESULTS The cohort was divided by clinical diagnosis into six groups: ketotic hypoglycemia (n=45, 29.2%), congenital hyperinsulinemic hypoglycemia (n=35, 22.7%), transient hyperinsulinemic hypoglycemia (n=28, 18.2%), metabolic disorder (n=14, 9.1%), systemic disease/syndrome (n=15, 9.7%), and hormone deficiencies (n=8, 5.2%). Two patients had insulinoma and in 7 (4.5%) no diagnosis was elucidated. At diagnosis, 58 (37.7%) were <1 month old, 23 (14.9%) aged 1-12 months, 58 (37.7%) aged 1-6 years, and 15 (9.7%) aged 6-18 years. Hypoglycemia etiology varied among neonates, infants, and children. In eight patients hypoglycemia was asymptomatic. Of 47 patients who completed a diagnostic fast, 31 became hypoglycemic, yet a significant added value for diagnosis was only found in 14 (29.8%) patients. CONCLUSIONS Hypoglycemia etiology in children is heterogeneous and varies by age. Any hypoglycemia measured in a child should be seriously evaluated as 7% are asymptomatic. Work-up should be tailored based on age, and clinical, biochemical, and imaging findings. Despite extensive work-up, in a significant number of patients the mechanism underlying pediatric hypoglycemia remains an enigma. This emphasizes the unmet needs and challenges in studying pediatric hypoglycemia.

Abstract
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.

Abstract
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 (β = 3.01 [SE = 0.97], p = 0.002), higher BMI-Z score (β = 2.08 [SE = 0.49], p < 0.001), higher HbA1c (β = 0.19 [SE = 0.03], p < 0.001) and treatment with multiple daily injections of insulin (β = 2.19 [SE = 1.02], p = 0.032). At type 1 diabetes diagnosis, higher BMI-Z score (β = 1.54 [SE = 0.63], p = 0.016) for those diagnosed before age 13 years and increased weight gain at 3 months post-diagnosis (β = 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.

Abstract
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 β-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.

Abstract
BACKGROUND A composite metric for the quality of glycemia from continuous glucose monitor (CGM) tracings could be useful for assisting with basic clinical interpretation of CGM data. METHODS We assembled a data set of 14-day CGM tracings from 225 insulin-treated adults with diabetes. Using a balanced incomplete block design, 330 clinicians who were highly experienced with CGM analysis and interpretation ranked the CGM tracings from best to worst quality of glycemia. We used principal component analysis and multiple regressions to develop a model to predict the clinician ranking based on seven standard metrics in an Ambulatory Glucose Profile: very low-glucose and low-glucose hypoglycemia; very high-glucose and high-glucose hyperglycemia; time in range; mean glucose; and coefficient of variation. RESULTS The analysis showed that clinician rankings depend on two components, one related to hypoglycemia that gives more weight to very low-glucose than to low-glucose and the other related to hyperglycemia that likewise gives greater weight to very high-glucose than to high-glucose. These two components should be calculated and displayed separately, but they can also be combined into a single Glycemia Risk Index (GRI) that corresponds closely to the clinician rankings of the overall quality of glycemia (r = 0.95). The GRI can be displayed graphically on a GRI Grid with the hypoglycemia component on the horizontal axis and the hyperglycemia component on the vertical axis. Diagonal lines divide the graph into five zones (quintiles) corresponding to the best (0th to 20th percentile) to worst (81st to 100th percentile) overall quality of glycemia. The GRI Grid enables users to track sequential changes within an individual over time and compare groups of individuals. CONCLUSION The GRI is a single-number summary of the quality of glycemia. Its hypoglycemia and hyperglycemia components provide actionable scores and a graphical display (the GRI Grid) that can be used by clinicians and researchers to determine the glycemic effects of prescribed and investigational treatments.

Abstract
OBJECTIVE Study aims: (1) developing and validating a novel questionnaire for measuring fear of hyperglycemia among parents of children with type 1 diabetes (T1D) - the Hyperglycemia Fear Survey - Parent version (FoHyper-P); (2) investigating correlations between parental fear of hyperglycemia and objective measures of glycemic control. RESEARCH DESIGN AND METHODS A multi-center, multi-national 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 Hypoglycemia 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 behavior 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 hyperglycemia as well as between worry subscales and a higher HbA1C in the past year, percent of hyperglycemia and lower TIR. CONCLUSIONS The FoHyper-P is a novel, validated tool for assessing parental fear of hyperglycemia. Integrating it into clinical practice addresses an underestimated aspect of parental diabetes management, enabling better care for children with T1D.

Abstract
Chronic inflammation in childhood is associated with impaired growth. In the current study, a lipopolysaccharide (LPS) model of inflammation in young rats was used to study the efficacy of whey-based as compared to soy-based diets to ameliorate growth attenuation. Young rats were injected with LPS and fed normal chow or diets containing whey or soy as the sole protein source during treatment, or during the recovery period in a separate set of experiments. The body and spleen weight, food consumption, humerus length, and EGP height and structure were evaluated. Inflammatory markers in the spleen and markers of differentiation in the EGP were assessed using qPCR. The LPS led to a significant increase in the spleen weight and a decrease in the EGP height. Whey, but not soy, protected the animals from both effects. In the recovery model, whey led to increased EGP height at both 3 and 16 d post treatment. The most affected region in the EGP was the hypertrophic zone (HZ), which was significantly shortened by the LPS treatment but enlarged by whey. In conclusion, LPS affected the spleen weight and EGP height and had a specific effect on the HZ. Nutrition with whey protein appeared to protect the rats from the LPS-induced growth attenuation.

Abstract
The significant and growing global prevalence of diabetes continues to challenge people with diabetes (PwD), healthcare providers, and payers. While maintaining near-normal glucose levels has been shown to prevent or delay the progression of the long-term complications of diabetes, a significant proportion of PwD are not attaining their glycemic goals. During the past 6 years, we have seen tremendous advances in automated insulin delivery (AID) technologies. Numerous randomized controlled trials and real-world studies have shown that the use of AID systems is safe and effective in helping PwD achieve their long-term glycemic goals while reducing hypoglycemia risk. Thus, AID systems have recently become an integral part of diabetes management. However, recommendations for using AID systems in clinical settings have been lacking. Such guided recommendations are critical for AID success and acceptance. All clinicians working with PwD need to become familiar with the available systems in order to eliminate disparities in diabetes quality of care. This report provides much-needed guidance for clinicians who are interested in utilizing AIDs and presents a comprehensive listing of the evidence payers should consider when determining eligibility criteria for AID insurance coverage.

Abstract
INTRODUCTION Data on adult height (AHt) in individuals with non-classical congenital adrenal hyperplasia (NCCAH) are inconsistent. METHODS We conducted a retrospective study of 109 females diagnosed with NCCAH at age <18 years who reached AHt. We studied AHt compared to target height (THt) and the correlation of AHt with clinical parameters. RESULTS The mean age at diagnosis was 9.7 ± 4.4 years; the mean follow-up was 10.9 ± 6.3 years. Hydrocortisone treatment (11.0 ± 5.0 mg/m2) was initiated at age 9.7 ± 4.0 years. Bone age was more advanced in girls who presented with central precocious puberty or early puberty (CPP/EP) (n = 43) than with timely puberty. AHt-standard deviation score (SDS) was lower than Ht-SDS at diagnosis (-0.8 ± 1.0 vs. +0.2 ± 1.3; p < 0.001) and -0.3 SDS shorter than THt (p < 0.001). Height, weight, and body mass index-SDS at last visits were similar between patients treated with glucocorticoids (n = 92) and those never treated (n = 17). AHt was comparable between patients with timely puberty and with CPP/EP, with no difference between those treated or not by GnRH analogue. AHt was similar between patients who were fully pubertal (Tanner 5), pre-pubertal (Tanner 1), and pubertal (Tanner 2-4) at diagnosis (158.0 ± 7.6, 158.1 ± 6.1, and 157.5 ± 6.5, respectively; p = 0.9). AHt-SDS was correlated with THt (R = 0.67, p < 0.001) and Ht-SDS at diagnosis (R = 0.7, p < 0.001) but not with age at diagnosis (R = -0.05, p = 0.6), the extent of bone age advancement (R = -0.04, p = 0.72), glucocorticoid treatment duration (R = -0.11, p = 0.34), or dose (R = -0.04, p = 0.70). CONCLUSION AHt of females diagnosed with NCCAH in childhood was lower than their THt. Glucocorticoid treatment duration and dose, pubertal status at diagnosis, and having CPP or EP were not correlated with AHt.

Abstract
Randomised controlled trials and other prospective clinical studies for novel medical interventions in people with diabetes have traditionally reported HbA1c as the measure of average blood glucose levels for the 3 months preceding the HbA1c test date. The use of this measure highlights the long-established correlation between HbA1c and relative risk of diabetes complications; the change in the measure, before and after the therapeutic intervention, is used by regulators for the approval of medications for diabetes. However, with the increasing use of continuous glucose monitoring (CGM) in clinical practice, prospective clinical studies are also increasingly using CGM devices to collect data and evaluate glucose profiles among study participants, complementing HbA1c findings, and further assess the effects of therapeutic interventions on HbA1c. Data is collected by CGM devices at 1-5 min intervals, which obtains data on glycaemic excursions and periods of asymptomatic hypoglycaemia or hyperglycaemia (ie, details of glycaemic control that are not provided by HbA1c concentrations alone that are measured continuously and can be analysed in daily, weekly, or monthly timeframes). These CGM-derived metrics are the subject of standardised, internationally agreed reporting formats and should, therefore, be considered for use in all clinical studies in diabetes. The purpose of this consensus statement is to recommend the ways CGM data might be used in prospective clinical studies, either as a specified study endpoint or as supportive complementary glucose metrics, to provide clinical information that can be considered by investigators, regulators, companies, clinicians, and individuals with diabetes who are stakeholders in trial outcomes. In this consensus statement, we provide recommendations on how to optimise CGM-derived glucose data collection in clinical studies, including the specific glucose metrics and specific glucose metrics that should be evaluated. These recommendations have been endorsed by the American Association of Clinical Endocrinologists, the American Diabetes Association, the Association of Diabetes Care and Education Specialists, DiabetesIndia, the European Association for the Study of Diabetes, the International Society for Pediatric and Adolescent Diabetes, the Japanese Diabetes Society, and the Juvenile Diabetes Research Foundation. A standardised approach to CGM data collection and reporting in clinical trials will encourage the use of these metrics and enhance the interpretability of CGM data, which could provide useful information other than HbA1c for informing therapeutic and treatment decisions, particularly related to hypoglycaemia, postprandial hyperglycaemia, and glucose variability.

Pediatr Res 2023; 93:233-241. [PMID: 35538247 DOI: 10.1038/s41390-022-02098-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 04/05/2022] [Accepted: 04/09/2022] [Indexed: 01/28/2023]
Abstract
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.

Abstract
Abstract
Background
Children with growth hormone deficiency (GHD) are treated with recombinant human growth hormone (rhGH), usually administered as a daily subcutaneous injection. Long-acting hGH (LAGH) treatments (approved and in development) have the potential to improve adherence and treatment outcomes. Somatrogon is a LAGH currently being developed as a once-weekly injectable treatment for GHD. The Pfizer Registry of Outcomes in Growth hormone RESearch (PROGRES) study was initiated to assess the long-term safety and effectiveness of Genotropin and other hGH formulations to treat GHD under routine clinical care.
Goals & aims: The overall goal of the registry is to increase our understanding of hGH treatments as used in a real-world setting. Enrolling children treated with different daily hGH brands as well as somatrogon (if approved in a given geography) will enable comparison between daily and LAGH, and across daily hGH brands. The primary objectives of the study are to describe and compare the safety and effectiveness of daily and LAGH treatments in children. Secondary objectives include evaluating adherence to hGH treatments and the health-related quality of life (HRQoL) and treatment experience of patients receiving hGH treatments.
Methods
For this non-interventional, prospective, phase 4 cohort study, eligible patients (male or female at any age) from >20 countries are planned for inclusion, with the aim of targeting 667 patients across the daily hGH brands in each of the three geographic regions. Patients will be enrolled from September 2021 to October 2029, with data collection planned until October 2030. Study inclusion criteria include prescription of daily Genotropin or other approved hGH treatments for GHD and the provision of informed consent/assent. If somatrogon is approved by regulatory agencies, somatrogon-treated patients will also be eligible for inclusion. Patients participating in any interventional clinical trials at the time of enrollment will be excluded from the study. Patients will be followed until the end of the study, withdrawal of consent, death, switch to an excluded hGH, or loss to follow-up, whichever occurs first. In addition to demographic and clinical characteristics, information on hGH treatment brand, dose and start/end dates will be collected, along with reasons for switching or discontinuing treatment. Primary safety outcomes include adverse events (AEs), serious AEs, and AEs of special interest. Primary effectiveness outcomes include annual height velocity (HV) and change in HV standard deviation scores. Treatment adherence, compliance outcomes, HRQoL, and patient treatment experience will be assessed.
Conclusions
The findings from the PROGRES study will provide valuable insights into the use of somatrogon, Genotropin and other approved hGH treatments in real-world clinical practice, specifically with regard to the long-term safety and effectiveness of these treatments as well as treatment compliance and patient HRQoL.

The COVID-19 Pandemic Affects Seasonality, With Increasing Cases of New-Onset Type 1 Diabetes in Children, From the Worldwide SWEET Registry. Diabetes Care 2022; 45:2594-2601. [PMID: 36166593 DOI: 10.2337/dc22-0278] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 08/19/2022] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To analyze whether the coronavirus disease 2019 (COVID-19) pandemic increased the number of cases or impacted seasonality of new-onset type 1 diabetes (T1D) in large pediatric diabetes centers globally. RESEARCH DESIGN AND METHODS We analyzed data on 17,280 cases of T1D diagnosed during 2018-2021 from 92 worldwide centers participating in the SWEET registry using hierarchic linear regression models. RESULTS The average number of new-onset T1D cases per center adjusted for the total number of patients treated at the center per year and stratified by age-groups increased from 11.2 (95% CI 10.1-12.2) in 2018 to 21.7 (20.6-22.8) in 2021 for the youngest age-group, <6 years; from 13.1 (12.2-14.0) in 2018 to 26.7 (25.7-27.7) in 2021 for children ages 6 to <12 years; and from 12.2 (11.5-12.9) to 24.7 (24.0-25.5) for adolescents ages 12-18 years (all P < 0.001). These increases remained within the expected increase with the 95% CI of the regression line. However, in Europe and North America following the lockdown early in 2020, the typical seasonality of more cases during winter season was delayed, with a peak during the summer and autumn months. While the seasonal pattern in Europe returned to prepandemic times in 2021, this was not the case in North America. Compared with 2018-2019 (HbA1c 7.7%), higher average HbA1c levels (2020, 8.1%; 2021, 8.6%; P < 0.001) were present within the first year of T1D during the pandemic. CONCLUSIONS The slope of the rise in pediatric new-onset T1D in SWEET centers remained unchanged during the COVID-19 pandemic, but a change in the seasonality at onset became apparent.
