Barriers and Facilitators of Management of Type-1 Diabetes in Children: A Socio-Cultural Enquiry of Caregivers’ Perspectives Living in Resource-Constrained Settings

Purpose Caregivers are key stakeholders in management of children with Type 1 Diabetes (T1D), but their perspectives have remained understudied, especially in the developing countries. This study explores their perspectives on the barriers and facilitators of management of a child with T1D in a resource-constrained setting. Methods This qualitative study, conducted in a tertiary level diabetes clinic in India, included parents of children with T1D, selected from subgroups varying in disease duration, education, habitat, and socioeconomic status, who participated in one of the five Focused Group Discussions (FGDs) of 60–90 min duration. The topic guide included questions like "What are the barriers you face related to diabetes care of your child at home or school?" and "What do you think helps you in managing a child with diabetes?" FGDs were audio-recorded, transcribed verbatim, and inductive coding was done independently by two authors. Results Twenty-eight parents (nineteen mothers and nine fathers, mean age: 35.1 years) of children aged between 2–13 years, were recruited till data saturation. Themes related to barriers of management were, ‘balancing nutrition and glycemic control is challenging’, ‘diabetes management involves psychological burden’ and ‘operational challenges’. Parents opined that family support, gaining decision-making and problem-solving attitude and optimal school-time management helped. Conclusion Parents living in resource-constrained circumstances perceive unique challenges during management of T1D in their children like social stigma, illiteracy, financial and logistic issues like procuring and storing essential supplies. A better understanding of these factors can aid healthcare professionals in managing them.

Feasibility and Acceptability of a Self-Guided Digital Family Skills Management Intervention for Children Newly Diagnosed With Type 1 Diabetes: Pilot Randomized Controlled Trial.

Family dynamics play an important role in determining the glycemic outcomes of type 1 diabetes (T1D) in children. The time interval immediately following T1D diagnosis is particularly stressful for families, and interventions to support families in adjusting their family practices to support adjustment to and management of T1D in the months following diagnosis may improve glycemic outcomes. Self-guided digital interventions offer a sustainable model for interventions to support caregivers in learning evidence-based family management skills for adjustment to and management of T1D. We hypothesized that a self-guided, web-based, family skills management program (addressing caregiver social support as well as family problem-solving, communication, and supportive behavior change strategies) initiated at the time of T1D diagnosis would improve glycemic outcomes in children with T1D. In this study, we report on the feasibility and acceptability of this program. We prospectively evaluated a sample of 37 children newly diagnosed with T1D recruited from a pediatric endocrinology clinic. Parent participants were asked to complete web-based modules addressing social support, family problem-solving, communication, and supportive behavior change strategies. Module completion was analyzed for percentage completion, patterns of completion, and differences in completion rates by coparenting status. Qualitative open-ended feedback was collected at the completion of each module. A total of 31 (84%) of the 37 participants initiated the web-based program. Of those 31 participants, 25 (81%) completed some content and 15 (48%) completed all 5 modules. Completion rates were higher when coparenting partners engaged in the intervention together (P=.04). Of the 18 participants given a choice about the spacing of content delivery, 15 (83%) chose to have all sessions delivered at once and 3 (17%) chose to space sessions out at 2-week intervals. Qualitative feedback supported the acceptability of the program for delivery soon after T1D diagnosis. Families reported on positive benefits, including requesting future access to the program and describing helpful changes in personal or family processes for managing T1D. In this study, we found that a self-guided digital family support intervention initiated at the time of a child's T1D diagnosis was largely feasible and acceptable. Overall, rates of participation and module completion were similar to or higher than other self-guided digital prevention interventions for mental and physical health outcomes. Self-guided digital programs addressing family management skills may help prevent challenges common with T1D management and can decrease cost, increase access, and add flexibility compared to traditional interventions.

Assessment of diabetes-specific knowledge and its determinants among children with type 1 diabetes mellitus and their primary caregivers: Experience from a tertiary care center in North India.

Assessment of diabetes-specific knowledge among children with type 1 diabetes (T1D) and their caregivers using a validated diabetes knowledge test (DKT) and to determine the factors associated with DKT score. A cross-sectional study was conducted in a tertiary care hospital, New Delhi (India). Children 5-18 years with T1D and caregivers were evaluated using a validated DKT tool to assess knowledge in basic and advance domains. The factors associated with DKT scores were studied. 110 T1D children with mean (SD) age 12.2 (3.3) years and duration 5.3 (2.7) years were assessed. The mean (SD) composite DKT score (%) was 58.0 (11.1) while in basic and advance domains were 66.4 (9.5) and 50.4(1.5), respectively. Maternal education (≥graduate), socio-economic strata (≥upper middle), annual per capita income (>Rs 50,000/700 USD), urban setting and HbA1c<8.5 % were significantly associated with higher odds of DKT score>50 %. HbA1c<8.5 % and urban setting were significant predictors of the DKT score on multivariate logistic regression analysis (p<0.001). DKT can identify individual challenges in specific (basic or advance) domains related to diabetes self-management skills. Higher maternal education significantly impacted achieving a high DKT score and improved glycemic control.

The importance of arterial stiffness in pediatric patients with type 1 diabetes mellitus: What's new?

Youths with type 1 diabetes (T1D) exhibits higher levels of pulse wave velocity (PWV) compared to healthy controls. Higher PWV in T1D subjects is associated with increased hazard of progression in albuminuria, decline in eGFR, cardiovascular (CV) events and mortality. In the recently published work by Georeli et al., increased PWV was associated with poor glycemic control as expressed by time-in-range (TIR) < 50 % in T1D children, adolescents and young adults. This finding is of great interest, since it is well known that glycemic control, as measured by TIR, is an important contributor of CV risk. The duration of TIR < 50 % is not reported by the authors, but is of importance, knowing that CGM provide data for the last 3–6 months, depending on the CGM model. In conclusion, PWV looks promising for risk stratification in T1D, but its exact role in T1D still remains to be fully explored.

Does insulin pump therapy offer benefits for behaviour, mood, cognition and HbA1c in children and adolescents with type 1 diabetes? A randomised controlled trial with observational follow-up

AimsImproved behaviour, mood, cognition and HbA1c have been reported with short-term use of continuous subcutaneous insulin infusion (CSII) in youth with type 1 diabetes (T1D). We sought to re-examine these...

Family History of Diabetes and Clinical Characteristics in Children at Diagnosis of Type 1 Diabetes-A Swedish Population-Based Study.

To compare the prevalence of parental diabetes between children with and without type 1 diabetes (T1D), and to compare clinical characteristics at diagnosis of T1D in children with, versus without, a family history of diabetes. Parental diabetes among children with T1D was compared with a general population cohort. Clinical characteristics were compared by family history of diabetes in parents and grandparents of 3,603 children with T1D using relative risk (RR) and ANOVA. Children with T1D more often had parents with type 2 diabetes (T2D) (RR 1.88; P < 0.001) than did children without diabetes. Children with T1D and a family history of T2D were more likely to be overweight or obese (P = 0.002). A family history of T2D and being overweight may contribute to increased risk of T1D.

Potential contribution of gut microbiota in the development of autoantibodies in T1D children carrying HLA-DRB1/DQB1 risk alleles: an experimental and in silico analysis.

This study aimed to investigate the prevalence of insulin autoantibody (IAA), glutamic acid decarboxylase antibody (GADA), and insulinoma-associated antigen-2 antibody (IA-2A) in type 1 diabetes (T1D) children based on the presence of predisposing HLA-II alleles. Additionally, to assess the sequence homology between autoantigens of islet cells and selected proteins derived from gut bacteria in terms of their binding capacities to HLA risk alleles, HLA-DRB1/DQB1 alleles were determined by PCR-SSOP in 111 T1D children (probands) along with 222 parents and 133 siblings. Autoantibodies were measured by ELISA, and in silico analysis was run as follows: protein extraction, homology and epitope prediction, peptide alignment, and HLA-peptide docking. Higher significant frequencies of DRB1*03:01, DQB1*02:01, and DQB1*03:02 alleles and DRB1*03:01 ~ DQB1*02:01 haplotype and lower frequencies of DRB1*11:01, DRB1*14:01, and DQB1*03:01 alleles were found in probands compared to parents and siblings. DRB1*11:01 ~ DQB1*03:01, DRB1*14:01 ~ DQB1*05:03, and DRB1*15:01-DQB1*06:02 haplotypes were significantly less frequent in the probands compared to parents. Out of 111 probands, 21 were seronegative, 90 tested positive for one autoantibody, and 15 showed the concurrent presence of three autoantibodies. Logistic regression analysis revealed that DRB1*04 ~ DQB1*03:02 haplotype was associated with the induction of GADA and IA-2A, while DRB1*11:01 ~ DQB1*03:01 was associated with seronegativity. Epitopes derived from GAD and gut bacteria showed strong binding capacities to HLA risk alleles. Due to the sequence similarities between gut bacteria-derived proteins and islet cell autoantigens and their potential for binding to HLA risk alleles, dysbiosis of gut microbiota can be considered another risk factor for the development of T1D, especially in genetically susceptible individuals.

Early Onset of Type 1 Diabetes in Kuwait: Distinct Clinical, Metabolic, and Immunological Characteristics.

Exploring early-onset diabetes in terms of describing characteristics at time of diagnosis might aid in a better understanding of etiology and may have implications on management and prevention. The aim of this study was to investigate the prevalence of early-onset type 1 diabetes (T1D) in Kuwait as well as describe their baseline clinical, biochemical, and immunological characteristics. Medical records of children newly diagnosed with T1D and registered in the Childhood-Onset Diabetes electronic Registry (CODeR) in Kuwait between 2017 and 2022 were reviewed. Early-onset T1D was defined as diagnosis at age younger than 6 years. 2,051 children were registered with new-onset T1D between 2017 and 2022, of which 657 (32.0%) were diagnosed at early onset. There has been a trend of slight increase in the percentage of early-onset T1D after 2020 (15.2%) with a prevalence of 18.4% and 20.2% in 2021 and 2022, respectively (p = 0.056). Age at onset was inversely related to admission to the pediatric intensive care unit (OR = 0.90, 95% CI: 0.85, 0.95, p &lt; 0.0001) and was directly related to positive celiac autoimmunity (p = 0.022), higher hemoglobin A1C (p &lt; 0.0001), and C-peptide levels (p &lt; 0.0001). However, age at onset of T1D was inversely related to the higher vitamin D levels (p &lt; 0.0001). These findings reinforce the need for increased attention to be given to study the development of T1D in children of younger age. This in turn will support special management and prevention measures targeted toward this vulnerable age group.

COVID-19 and Type 1 Diabetes.

The coronavirus disease 2019 (COVID-19) pandemic brought about several challenges for pediatric patients that were considerably different than those for adult patients. While adult patients had severe illness with associated respiratory and multiorgan failure and subsequent death, pediatric patients typically had milder disease. There were increases in postinfection complications, including an increased incidence of new-onset type 1 diabetes (T1D) following COVID-19 infection, particularly in adolescent patients. Currently, there is increasing concern that COVID-19 infection may be contributing to the development of T1D. This review will provide an overview of COVID-19, T1D, and the increased incidence noted during the pandemic, and the proposed mechanism of development of T1D in this specific patient demographic. Future studies will be needed to understand the long-term impact of the COVID-19 pandemic on T1D in children and adolescents. [Pediatr Ann. 2024;53(7):e244-e248.].

Evaluation of epicardial adipose tissue in children with type 1 diabetes.

Epicardial adipose tissue (EAT), the visceral fat surrounding the heart between the myocardium and visceral pericardium, intersects with Type 1 diabetes (T1D). This review aims to elucidate the intricate association between EAT and childhood T1D. In this retrospective study, two pediatric groups were involved children with type 1 diabetes, and healthy children. Epicardial fat thickness was measured appropriately, and the study documented HbA1c levels and time to diabetes diagnosis for comprehensive analysis. Encompassing 51 children with T1D and 69 healthy controls, revealed that children with type 1 diabetes had a mean HbA1c level of 9.4 ± 0.2, and a mean insulin dose of 0.94 units/kg/day. Epicardial adipose tissue (EAT) values were significantly higher in the Type 1 DM group. It has been shown that epicardial fat thickness may have a specific and sensitive value in type 1 diabetics. The increased presence of epicardial fat tissue in children with type 1 diabetes is highlighted, prompting the consideration of various mechanisms. However, the complexity of this relationship underscores the need for further studies to provide a more comprehensive understanding of the underlying factors. Ongoing research in this area is crucial for advancing our knowledge and potential therapeutic interventions. Cardiac complications are one of the most important causes of morbidity and mortality in people with type 1 diabetes. Being able to detect cardiological complications of diabetes at an early stage contributes to morbidity. We found that epicardial fat tissue thickness was thicker in children with type 1 diabetes than in healthy children. Epicardial fat tissue thickness may be associated with poor control in children with type 1 diabetes and maybe a guide in terms of cardiac risks.

The increase in diabetes in children from underdeveloped countries.

The incidence of type 1 diabetes (T1D) in children and adolescents has been increased over decades worldwide. Recent studies showed that the trend of T1D incidences were different between developed and underdeveloped countries. This review aimed to summarize the changes of childhood T1D incidences in underdeveloped countries over the past decade. Majority of the underdeveloped countries lacked of nationwide population-based studies on childhood T1D. We reviewed the trend of childhood T1D in important underdeveloped countries with available data in recent years. The incidences of childhood T1D in underdeveloped countries were low decades ago, but it increased significantly recently, particularly in the sub-Saharan African, Middle East and North African regions. The incidences of childhood T1D increased significantly in underdeveloped countries, especially in the sub-Saharan African, Middle East and North African regions. T1D registry and population-based studies are helpful to understand the situation and characteristic of childhood T1D in underdeveloped countries.

Clinico-Metabolic Profile and Follow-Up of Familial Cases Compared to Sporadic Cases in a Lyon Series of Type 1 Diabetic Children.

This study aimed to describe the clinical, biochemical, therapeutic, and progressive characteristics of children with familial type 1 diabetes (T1D) compared to those with non-familial T1D. Compare within the first group, the phenotype of type 1 diabetics inherited from the father with those inherited from the mother. We conducted a retrospective study lasting 10 years at the L'hôpital Femme Mère Enfant (Woman-Mother-Child Hospital) in Lyon, France. Cases were any child diagnosed with T1D for at least 12 months who had a parent with T1D. Each case was matched with a T1D control without a family history of T1D, of the same age, same sex and same year of discovery. Cases group was divided into two subgroups according to the sex of the parent with T1D. A total of 43 children had a TD1 parent (family group) of whom 27 cases were the father. Forty four T1D children without any T1D parent were matched (sporadic group). The family group had consulted earlier (p < 0.001), were less in initial diabetic ketoacidosis (p = 0.016), and had a lower HbA1C level lower (p < 0.001) and lower initial insulin requirements (p < 0.001). During follow-up, it was noted that the evolution of Hb1AC, insulin requirements, and chronic complications were similar in familial and non-familial cases (p = 0.943, p = 0.450, p = 0.664, respectively). The patients in the T1D mother group seemed better balanced than those of the T1D father with an average HbA1C at 10 years of follow-up of 7.82% in the maternal group compared to 9.10% in the paternal group (p = 0.021). This study shows that familial T1D is a protective factor against the initial severity of T1D in offspring. Paternal T1D presents a more severe initial and progressive clinico-biological character than T1D inherited from the mother. However, during follow-up, other psycho-environmental factors could modify this observation.

Factors affecting care burden and life satisfaction among parents of children with type 1 diabetes

AimParents in the caregiving role for children with type 1 diabetes (T1D) are affected from many aspects including physically, psychologically, socially, financially and spiritually. The aim of this study was to determine the factors affecting the care burden and life satisfaction of parents caring for a child with T1D and to examine the relationship between them. MethodThis research was completed with 293 parents of children with T1D aged 3–18 years, attending the pediatric health and diseases clinics in two state hospitals located in [redacted for peer review] from May 2023 to September 2023. For collection of data, a survey form, the Zarit Burden Interview (ZBI) and Adult Life Satisfaction Scale (ALSS) were used. Analysis of data used percentages, means, one-way ANOVA (post-hoc Tukey test), independent samples t-test, regression and correlation tests. Statistical significance level was accepted as p < 0.05. ResultsParents had mean care burden scale scores of 56.30 ± 12.4, with mean adult life satisfaction scale scores of 69.39 ± 11.61. According to the regression analysis results, the ZBI scores were affected by the child's general health status after T1D diagnosis, impact on responsibilities after T1D diagnosis and diabetes management skills (p < 0.05). ALSS scores were affected by the variables of caregiver assessment of health status before and after the child's T1D diagnosis, income level, impact on responsibilities after T1D diagnosis and diabetes management skills (p < 0.05). There was a negative weak level of significant correlation identified between the ZBI and ALSS total scores (r = −0.36; p < 0.05). ConclusionGeneral health status after receiving T1D diagnosis, impact on responsibilities after diabetes diagnosis and diabetes management skills are factors affecting the care burden and life satisfaction of parents. Additionally, a negative relationship was determined between parents' care burden and life satisfaction. Nurses should develop family-centered care plans and work to reduce factors increasing care burden while increasing life satisfaction.

Evaluation of optical coherence tomography angiography metrics in children and adolescents with type 1 diabetes: 4-year longitudinal study

PurposeTo evaluate longitudinal changes in optical coherence tomography angiography (OCTA) metrics in children and adolescents with type 1 diabetes (T1D).MethodsThis prospective observational cohort study included thirty-two eyes from thirty T1D children with no history of diabetic retinopathy (DR) who were followed up for 4 years. Participants underwent OCTA examinations at baseline and during follow-up. Quantitative OCTA metrics were measured using a customized MATLAB algorithm. Generalized mixed-effect models were used to determine their relationship with DR development. Systemic parameters and OCTA metrics were screened using least absolute shrinkage and selection operator to identify predictors for visual function.ResultsOver the 4-year period, seven of the included eyes developed DR, and most OCTA metrics decreased with diabetes duration. Higher peripapillary and parafoveal nasal quadrant vessel area density (VAD) in the superficial capillary plexus (SCP) and vessel skeleton density (VSD) in both the SCP and the deep capillary plexus (DCP) were associated with a lower risk of DR in T1D. Parafoveal DCP VSD and VAD in the temporal and inferior quadrants were anticorrelated with changes in best corrected visual acuity.ConclusionsOCTA metrics dynamically change over the duration of diabetes and can be used as biomarkers to improve the risk evaluation of DR development and visual function in T1D children and adolescents.

Incidences of newly diagnosed childhood diabetes and onset severity: a multicenter regional study in Thailand over two decades and during the COVID-19 pandemic.

While global incidence rates (IR) of childhood diabetes are increasing, there is a notable lack of current informationon theincidence of childhood-onset diabetesin Thailand. This study aims to illustrate the age-standardized IR and types of childhood diabetes using multicenter regional data in Northern Thailand from 2005 to 2022 and to assess the impact of the COVID-19 pandemic. Data on newly diagnosed childhood diabetes were retrospectively collected between 2005 and 2016 and prospectively recorded for all incident cases between 2016 and 2022. The capture-recapture method was applied to estimate the completeness of ascertainment. The age-standardized IR of diabetes was calculated. The IR of diabetes and the prevalence/severity of DKA at onset were compared between the pre-pandemic and pandemic periods. Among 210 patients, type 1 diabetes (T1D) accounted for 56.2 %, type 2 diabetes (T2D) for 39 %, and other types for 4.8 %. The T1D age-standardized IR significantly increased from 0.30 in 2005 to 3.11/100,000 person/year in 2022, mirroring the T2D trend, which increased from 0.33 to 3.15/100,000 person/year. The average T1D age-standardized IR, including the prevalence/severity of DKA at diagnosis, did not significantly differ between the pre-pandemic and pandemic periods (2.11 vs. 2.36/100,000 person/year, p-value=0.67). However, the average T2D age-standardized IR significantly increased from 0.83 to 2.15/100,000 person/year during the pandemic (p-value=0.0057). This study highlights an increased incidence of childhood T1D and T2D in Northern Thailand over a two-decade period. Notably, during the COVID-19 pandemic, the T1D incidence remained stable, while a significant rise in T2D incidence was observed.

Impact of a Mediterranean diet, physical activity, body composition, and insulin delivery methods on metabolic control in children with type 1 diabetes.

To evaluate the synergistic impact of diet, lifestyle and technology on glycemic control in children with type 1 diabetes (T1D). This cross-sectional study included 112 randomly selected patients with T1D from Gran Canaria (median age 12 years; 51.8% female). The study collected data on height, weight, body composition (bioimpedance), age, disease duration, and method of insulin delivery. Physical activity was evaluated using the Krece questionnaire and an accelerometer (GENEActiv). Adherence to the Mediterranean diet was assessed using the KIDMED Quick Nutrition Test. Glycemic control was evaluated using HbA1c and the percentage of time in range. SPSS version 21 and RStudio were used for statistical analysis of the data. Stepwise linear regression analysis (backwards) was used to identify factors independently associated with metabolic control. Insulin pump use, age and adherence to the Mediterranean diet were found to be significantly and independently associated with better glycemic control, whereas years with T1D was associated with worse HbA1c values. No relationship was found between body composition and physical activity measured by accelerometry or questionnaire. Adherence to the Mediterranean diet, insulin delivery methods, age, and number of years with T1D are important factors to consider in the management of T1D in children.

Fracture patterns and associated risk factors in pediatric and early adulthood type 1 diabetes: Findings from a nationwide retrospective cohort study

PurposePeople with pediatric and early adulthood type 1 diabetes (T1D) might have a higher fracture risk at several sites compared to the general population. Therefore, we assessed the hazard ratios (HR) of various fracture sites and determined the risk factors associated with fractures among people with newly diagnosed childhood and adolescence T1D. MethodsAll people from the UK Clinical Practice Research Datalink GOLD (1987–2017), below 20 years of age with a T1D diagnosis code (n = 3100) and a new insulin prescription, were included and matched 1:1 by sex, age, and practice to a control without diabetes. Cox regression was used to estimate HRs of any, major osteoporotic fractures (MOFs) and peripheral fractures (lower-arm and lower-legs) for people with T1D compared to controls. The analyses were adjusted for sex, age, diabetic complications, medication (glucocorticoids, anti-depressants, anxiolytics, bone medication, anti-convulsive), Charlson-comorbidity-index (CCI), hypoglycemia, falls and alcohol. T1D was further stratified by diabetes duration, presence of diabetic microvascular complications (retinopathy, nephropathy, and neuropathy) and boys versus girls. ResultsThe crude HRs for any fracture (HR: 1.30, CI95%: 1.11–1.51), lower-arm (HR: 1.22, CI95%: 1.00–1.48), and lower-leg fractures (HR: 1.54, CI95%: 1.11–2.13) were statistically significant increase in T1D compared to controls, but the effect disappeared in the adjusted analyses. For MOFs, no significant differences were seen. Risk factors in the T1D cohort were few, but the most predominantly one was a previous fracture (any fracture: HR: 2.00, CI95%: 1.70–2.36; MOFs: HR: 1.89, CI95%: 1.44–2.48, lower- arm fractures: HR: 2.08, CI95%: 1.53–2.82 and lower-leg fractures: HR: 2.08, CI95%: 1.34–3.25). Others were a previous fall (any fracture: HR: 1.54, CI95%: 1.20–1.97), hypoglycemia (Any fracture: HR: 1.46, CI95%: 1.21–1.77 and lower-leg fractures: HR: 2.34, CI95%: 1.47–3.75), and anxiolytic medication (Any fracture: HR: 1.52, CI95%: 1.10–2.11). Whereas girls had a lower risk compared to boys (Any fracture: HR: 0.78, CI95%: 0.67–0.90 and lower-arm fractures; HR: 0.51, CI95%: 0.38–0.68). The risk of any fracture in T1D did not increase with longer diabetes duration compared to controls (0–4 years: HR: 1.20, CI95%: 1.00–1.44; 5–9 years: HR: 1.17, CI95%: 0.91–1.50; <10 years: HR: 0.83, CI95%: 0.54–1.27). Similar patterns were observed for other fracture sites. Furthermore, one complication compared to none in T1D correlated with a higher fracture risk (1 complication: HR: 1.42, CI95%: 1.04–1.95). ConclusionThe overall fracture risk was not increased in pediatric and early adulthood T1D; instead, it was associated with familiar risk factors and specific diabetes-related ones.

No associations between type 1 diabetes and atopic dermatitis, allergic rhinitis, or asthma in childhood: a nationwide Danish case-cohort study

Studies examining the association between type 1 diabetes (T1D) and atopic diseases, i.e., atopic dermatitis, allergic rhinitis and asthma have yielded conflicting results due to different algorithms for classification, sample size issues and risk of referral bias of exposed cohorts with frequent contact to health care professionals. Using Danish national registries and well-established disease algorithms, we examined the bidirectional association between T1D and atopic diseases in childhood and adolescence using Cox Proportional Hazard regression compared to two different unexposed cohorts from a population of 1.5 million Danish children born from 1997 to 2018. We found no associations between T1D and atopic dermatitis, allergic rhinitis, or asthma (defined after age five). However, in multivariable analysis we found an increased risk of persistent wheezing (defined as asthma medication before age five) after T1D with an adjusted hazard ratio (aHR) of 1.70 [1.17–2.45]. We also identified an increased risk of developing T1D after persistent wheezing with aHR of 1.24 [1.13–1.36]. This study highlights similar risks of atopic diseases in children with T1D and of T1D in children with atopic disease after age of five years versus healthy controls. However, more research is needed to understand the possible early immunological effects of the link between persistent wheezing and T1D.

The Effect of COVID-19 on Type 1 Diabetes Occurrence among Children and Adolescents: A Multicenter Prospective Observational Cohort Study in Israel

Aim. The effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the pediatric occurrence of type 1 diabetes (T1D) is inconclusive. We aimed to assess associations between seroprevalences of the distinct anti-SARS-CoV-2 antibodies and T1D occurrence in children and adolescents. Methods. This multicenter prospective observational cohort comprised children diagnosed with T1D between October 2020 and July 2022 and unrelated children who performed endocrine tests (control group) in a 1 : 3 ratio. Anti-SARS-CoV-2 antibodies, including anti-S, anti-N, and neutralizing antibodies, were assessed in each group. Results. The cohort included 51 children with T1D and 182 children in the control group. The median (interquartile range) age was 11.4 (8.2, 13.3) years, with 45% being female. Increases were not observed in the seroprevalence of any of the anti-SARS-CoV-2 antibodies among the children with new-onset T1D compared to the control group. Among the T1D group, anti-S seroprevalence was higher among those without diabetic ketoacidosis (DKA) than in those with DKA upon T1D diagnosis (72% vs. 42%, p = 0.035 ). After adjustment to vaccination status, this difference was not statistically significant. Additionally, anti-N antibodies and neutralizing antibodies did not differ between the DKA and the non-DKA groups. None of the anti-SARS-CoV-2 antibodies were associated with any of the glycemic parameters. Conclusions. This study is the first to assess several distinct anti-SARS-CoV-2 antibodies in new-onset T1D, and our findings do not support an association between SARS-CoV-2 infection and the occurrence of T1D in children and adolescents. Since autoimmunity may emerge years after a viral infection, we recommend conducting follow-up epidemiological studies to assess whether there is a change in the incidence of T1D following the SARS-CoV-2 pandemic.

Regional audit on presentation in diabetic ketoacidosis(DKA) at the manifestation of type1 diabetes in children and young people within Yorkshire and Humber region (YH)

Regional audit on presentation in diabetic ketoacidosis(DKA) at the manifestation of type1 diabetes in children and young people within Yorkshire and Humber region (YH)
