Diabetes (type 1 and type 2) in children and young people: diagnosis and management

National Institute for Health and Care Excellence

This updated guideline covers the diagnosis and management of type 1 and type 2 diabetes in children and young people aged under 18. The guideline recommends how to support children and young people and their families and carers to maintain tight control of blood glucose to reduce the long-term risks associated with diabetes.

In May 2023, NICE reviewed the evidence and made new recommendations on blood glucose monitoring and management for children and young people with type 2 diabetes. For more details, see the update information.

Multisystem Inflammatory Syndrome in Children in New York State

BACKGROUND

A multisystem inflammatory syndrome in children (MIS-C) is associated with coronavirus disease 2019. The New York State Department of Health (NYSDOH) established active, statewide surveillance to describe hospitalized patients with the syndrome.

METHODS

Hospitals in New York State reported cases of Kawasaki’s disease, toxic shock syndrome, myocarditis, and potential MIS-C in hospitalized patients younger than 21 years of age and sent medical records to the NYSDOH. We carried out descriptive analyses that summarized the clinical presentation, complications, and outcomes of patients who met the NYSDOH case definition for MIS-C between March 1 and May 10, 2020.

RESULTS

As of May 10, 2020, a total of 191 potential cases were reported to the NYSDOH. Of 95 patients with confirmed MIS-C (laboratory-confirmed acute or recent severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] infection) and 4 with suspected MIS-C (met clinical and epidemiologic criteria), 53 (54%) were male; 31 of 78 (40%) were black, and 31 of 85 (36%) were Hispanic. A total of 31 patients (31%) were 0 to 5 years of age, 42 (42%) were 6 to 12 years of age, and 26 (26%) were 13 to 20 years of age. All presented with subjective fever or chills; 97% had tachycardia, 80% had gastrointestinal symptoms, 60% had rash, 56% had conjunctival injection, and 27% had mucosal changes. Elevated levels of C-reactive protein, d-dimer, and troponin were found in 100%, 91%, and 71% of the patients, respectively; 62% received vasopressor support, 53% had evidence of myocarditis, 80% were admitted to an intensive care unit, and 2 died. The median length of hospital stay was 6 days.

CONCLUSIONS

The emergence of multisystem inflammatory syndrome in children in New York State coincided with widespread SARS-CoV-2 transmission; this hyperinflammatory syndrome with dermatologic, mucocutaneous, and gastrointestinal manifestations was associated with cardiac dysfunction.

Multisystem Inflammatory Syndrome in U.S. Children and Adolescents

BACKGROUND

Understanding the epidemiology and clinical course of multisystem inflammatory syndrome in children (MIS-C) and its temporal association with coronavirus disease 2019 (Covid-19) is important, given the clinical and public health implications of the syndrome.

METHODS

We conducted targeted surveillance for MIS-C from March 15 to May 20, 2020, in pediatric health centers across the United States. The case definition included six criteria: serious illness leading to hospitalization, an age of less than 21 years, fever that lasted for at least 24 hours, laboratory evidence of inflammation, multisystem organ involvement, and evidence of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) based on reverse-transcriptase polymerase chain reaction (RT-PCR), antibody testing, or exposure to persons with Covid-19 in the past month. Clinicians abstracted the data onto standardized forms.

RESULTS

We report on 186 patients with MIS-C in 26 states. The median age was 8.3 years, 115 patients (62%) were male, 135 (73%) had previously been healthy, 131 (70%) were positive for SARS-CoV-2 by RT-PCR or antibody testing, and 164 (88%) were hospitalized after April 16, 2020. Organ-system involvement included the gastrointestinal system in 171 patients (92%), cardiovascular in 149 (80%), hematologic in 142 (76%), mucocutaneous in 137 (74%), and respiratory in 131 (70%). The median duration of hospitalization was 7 days (interquartile range, 4 to 10); 148 patients (80%) received intensive care, 37 (20%) received mechanical ventilation, 90 (48%) received vasoactive support, and 4 (2%) died. Coronary-artery aneurysms (z scores ≥2.5) were documented in 15 patients (8%), and Kawasaki’s disease–like features were documented in 74 (40%). Most patients (171 [92%]) had elevations in at least four biomarkers indicating inflammation. The use of immunomodulating therapies was common: intravenous immune globulin was used in 144 (77%), glucocorticoids in 91 (49%), and interleukin-6 or 1RA inhibitors in 38 (20%).

CONCLUSIONS

Multisystem inflammatory syndrome in children associated with SARS-CoV-2 led to serious and life-threatening illness in previously healthy children and adolescents. (Funded by the Centers for Disease Control and Prevention.)

Primary Care–Based Interventions to Prevent Illicit Drug Use in Children, Adolescents, and Young Adults

Importance  In 2017, an estimated 7.9% of persons aged 12 to 17 years reported illicit drug use in the past month, and an estimated 50% of adolescents in the US had used an illicit drug by the time they graduated from high school. Young adults aged 18 to 25 years have a higher rate of current illicit drug use, with an estimated 23.2% currently using illicit drugs. Illicit drug use is associated with many negative health, social, and economic consequences and is a significant contributor to 3 of the leading causes of death among young persons (aged 10-24 years): unintentional injuries including motor vehicle crashes, suicide, and homicide.

Objective  To update its 2014 recommendation, the USPSTF commissioned a review of the evidence on the potential benefits and harms of interventions to prevent illicit drug use in children, adolescents, and young adults.

Population  This recommendation applies to children (11 years and younger), adolescents (aged 12-17 years), and young adults (aged 18-25 years), including pregnant persons.

Evidence Assessment  Because of limited and inadequate evidence, the USPSTF concludes that the benefits and harms of primary care–based interventions to prevent illicit drug use in children, adolescents, and young adults are uncertain and that the evidence is insufficient to assess the balance of benefits and harms. More research is needed.

Recommendation  The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of primary care–based behavioral counseling interventions to prevent illicit drug use, including nonmedical use of prescription drugs, in children, adolescents, and young adults.

Primary Care Interventions for Prevention and Cessation of Tobacco Use in Children and Adolescents

Importance  Tobacco use is the leading cause of preventable death in the US. An estimated annual 480 000 deaths are attributable to tobacco use in adults, including from secondhand smoke. It is estimated that every day about 1600 youth aged 12 to 17 years smoke their first cigarette and that about 5.6 million adolescents alive today will die prematurely from a smoking-related illness. Although conventional cigarette use has gradually declined among children in the US since the late 1990s, tobacco use via electronic cigarettes (e-cigarettes) is quickly rising and is now more common among youth than cigarette smoking. e-Cigarette products usually contain nicotine, which is addictive, raising concerns about e-cigarette use and nicotine addiction in children. Exposure to nicotine during adolescence can harm the developing brain, which may affect brain function and cognition, attention, and mood; thus, minimizing nicotine exposure from any tobacco product in youth is important.

Objective  To update its 2013 recommendation, the USPSTF commissioned a review of the evidence on the benefits and harms of primary care interventions for tobacco use prevention and cessation in children and adolescents. The current systematic review newly included e-cigarettes as a tobacco product.

Population  This recommendation applies to school-aged children and adolescents younger than 18 years.

Evidence Assessment  The USPSTF concludes with moderate certainty that primary care–feasible behavioral interventions, including education or brief counseling, to prevent tobacco use in school-aged children and adolescents have a moderate net benefit. The USPSTF concludes that there is insufficient evidence to determine the balance of benefits and harms of primary care interventions for tobacco cessation among school-aged children and adolescents who already smoke, because of a lack of adequately powered studies on behavioral counseling interventions and a lack of studies on medications.

Recommendation  The USPSTF recommends that primary care clinicians provide interventions, including education or brief counseling, to prevent initiation of tobacco use among school-aged children and adolescents. (B recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of primary care–feasible interventions for the cessation of tobacco use among school-aged children and adolescents.

Association between maternal and paternal mental illness and risk of injuries in children and adolescents

Objective To determine the association between parental mental illness and the risk of injuries among offspring.

Design Retrospective cohort study.

Setting Swedish population based registers.

Participants 1 542 000 children born in 1996-2011 linked to 893 334 mothers and 873 935 fathers.

Exposures Maternal or paternal mental illness (non-affective psychosis, affective psychosis, alcohol or drug misuse, mood disorders, anxiety and stress related disorders, eating disorders, personality disorders) identified through linkage to inpatient or outpatient healthcare registers.

Main outcome measures Risk of injuries (transport injury, fall, burn, drowning and suffocation, poisoning, violence) at ages 0-1, 2-5, 6-9, 10-12, and 13-17 years, comparing children of parents with mental illness and children of parents without mental illness, calculated as the rate difference and rate ratio adjusted for confounders.

Results Children with parental mental illness contributed to 201 670.5 person years of follow-up, while children without parental mental illness contributed to 2 434 161.5 person years. Children of parents with mental illness had higher rates of injuries than children of parents without mental illness (for any injury at age 0-1, these children had an additional 2088 injuries per 100 000 person years; number of injuries for children with and without parental mental illness was 10 235 and 72 723, respectively). At age 0-1, the rate differences ranged from 18 additional transport injuries to 1716 additional fall injuries per 100 000 person years among children with parental mental illness compared with children without parental mental illness. A higher adjusted rate ratio for injuries was observed from birth through adolescence and the risk was highest during the first year of life (adjusted rate ratio at age 0-1 for the overall association between any parental mental illness that has been recorded in the registers and injuries 1.30, 95% confidence interval 1.26 to 1.33). Adjusted rate ratios at age 0-1 ranged from 1.28 (1.24 to 1.32) for fall injuries to 3.54 (2.28 to 5.48) for violence related injuries. Common and serious maternal and paternal mental illness was associated with increased risk of injuries in children, and estimates were slightly higher for common mental disorders.

Conclusions Parental mental illness is associated with increased risk of injuries among offspring, particularly during the first years of the child’s life. Efforts to increase access to parental support for parents with mental illness, and to recognise and treat perinatal mental morbidity in parents in secondary care might prevent child injury.

Trends in Diet Quality Among Youth in the United States, 1999-2016

Question  What was the quality of diets among youth in the United States and how did it change between 1999 and 2016?

Findings  In this serial cross-sectional analysis of nationally representative data from 31 420 youth, diet quality modestly improved from 1999-2000 to 2015-2016 based on validated dietary quality scores. The estimated proportion of children with poor-quality diet significantly decreased (from 76.8% to 56.1%), the estimated proportion with intermediate quality diet significantly increased (from 23.2% to 43.7%), and the estimated proportion with an ideal quality significantly increased but remained low (from 0.07% to 0.25%).

Meaning  From 1999 to 2016, the estimated overall diet quality of US youth modestly improved, but more than half of children still had poor-quality diets.

Liraglutide in Children and Adolescents with Type 2 Diabetes

BACKGROUND

Metformin is the regulatory-approved treatment of choice for most youth with type 2 diabetes early in the disease. However, early loss of glycemic control has been observed with metformin monotherapy. Whether liraglutide added to metformin (with or without basal insulin treatment) is safe and effective in youth with type 2 diabetes is unknown.

METHODS

Patients who were 10 to less than 17 years of age were randomly assigned, in a 1:1 ratio, to receive subcutaneous liraglutide (up to 1.8 mg per day) or placebo for a 26-week double-blind period, followed by a 26-week open-label extension period. Inclusion criteria were a body-mass index greater than the 85th percentile and a glycated hemoglobin level between 7.0 and 11.0% if the patients were being treated with diet and exercise alone or between 6.5 and 11.0% if they were being treated with metformin (with or without insulin). All the patients received metformin during the trial. The primary end point was the change from baseline in the glycated hemoglobin level after 26 weeks. Secondary end points included the change in fasting plasma glucose level. Safety was assessed throughout the course of the trial.

RESULTS

Of 135 patients who underwent randomization, 134 received at least one dose of liraglutide (66 patients) or placebo (68 patients). Demographic characteristics were similar in the two groups (mean age, 14.6 years). At the 26-week analysis of the primary efficacy end point, the mean glycated hemoglobin level had decreased by 0.64 percentage points with liraglutide and increased by 0.42 percentage points with placebo, for an estimated treatment difference of −1.06 percentage points (P<0.001); the difference increased to −1.30 percentage points by 52 weeks. The fasting plasma glucose level had decreased at both time points in the liraglutide group but had increased in the placebo group. The number of patients who reported adverse events was similar in the two groups (56 [84.8%] with liraglutide and 55 [80.9%] with placebo), but the overall rates of adverse events and gastrointestinal adverse events were higher with liraglutide.

CONCLUSIONS

In children and adolescents with type 2 diabetes, liraglutide, at a dose of up to 1.8 mg per day (added to metformin, with or without basal insulin), was efficacious in improving glycemic control over 52 weeks. This efficacy came at the cost of an increased frequency of gastrointestinal adverse events. (Funded by Novo Nordisk; Ellipse ClinicalTrials.gov number, NCT01541215. opens in new tab.)

Development and validation of a prediction model for fat mass in children and adolescents: meta-analysis using individual participant data

Objectives To develop and validate a prediction model for fat mass in children aged 4-15 years using routinely available risk factors of height, weight, and demographic information without the need for more complex forms of assessment.

Design Individual participant data meta-analysis.

Setting Four population based cross sectional studies and a fifth study for external validation, United Kingdom.

Participants A pooled derivation dataset (four studies) of 2375 children and an external validation dataset of 176 children with complete data on anthropometric measurements and deuterium dilution assessments of fat mass.

Main outcome measure Multivariable linear regression analysis, using backwards selection for inclusion of predictor variables and allowing non-linear relations, was used to develop a prediction model for fat-free mass (and subsequently fat mass by subtracting resulting estimates from weight) based on the four studies. Internal validation and then internal-external cross validation were used to examine overfitting and generalisability of the model’s predictive performance within the four development studies; external validation followed using the fifth dataset.

Results Model derivation was based on a multi-ethnic population of 2375 children (47.8% boys, n=1136) aged 4-15 years. The final model containing predictor variables of height, weight, age, sex, and ethnicity had extremely high predictive ability (optimism adjusted R2: 94.8%, 95% confidence interval 94.4% to 95.2%) with excellent calibration of observed and predicted values. The internal validation showed minimal overfitting and good model generalisability, with excellent calibration and predictive performance. External validation in 176 children aged 11-12 years showed promising generalisability of the model (R2: 90.0%, 95% confidence interval 87.2% to 92.8%) with good calibration of observed and predicted fat mass (slope: 1.02, 95% confidence interval 0.97 to 1.07). The mean difference between observed and predicted fat mass was −1.29 kg (95% confidence interval −1.62 to −0.96 kg).

Conclusion The developed model accurately predicted levels of fat mass in children aged 4-15 years. The prediction model is based on simple anthropometric measures without the need for more complex forms of assessment and could improve the accuracy of assessments for body fatness in children (compared with those provided by body mass index) for effective surveillance, prevention, and management of clinical and public health obesity.
