The Silent Epidemic of Diabetic Ketoacidosis at Diagnosis of Type 1 Diabetes in Children and Adolescents in Italy During the COVID-19 Pandemic in 2020.

Aim/Hypothesis: To compare the frequency of diabetic ketoacidosis (DKA) at diagnosis of type 1 diabetes in Italy during the COVID-19 pandemic in 2020 with the frequency of DKA during 2017-2019. Methods: Forty-seven pediatric diabetes centers caring for >90% of young people with diabetes in Italy recruited 4,237 newly diagnosed children with type 1 diabetes between 2017 and 2020 in a longitudinal study. Four subperiods in 2020 were defined based on government-imposed containment measures for COVID-19, and the frequencies of DKA and severe DKA compared with the same periods in 2017-2019. Results: Overall, the frequency of DKA increased from 35.7% (95%CI, 33.5-36.9) in 2017-2019 to 39.6% (95%CI, 36.7-42.4) in 2020 (p=0.008), while the frequency of severe DKA increased from 10.4% in 2017-2019 (95%CI, 9.4-11.5) to 14.2% in 2020 (95%CI, 12.3-16.4, p<0.001). DKA and severe DKA increased during the early pandemic period by 10.4% (p=0.004) and 8% (p=0.002), respectively, and the increase continued throughout 2020. Immigrant background increased and high household income decreased the probability of presenting with DKA (OR: 1.55; 95%CI, 1.24-1.94; p<0.001 and OR: 0.60; 95 CI, 0.41-0.88; p=0.010, respectively). Conclusions/Interpretation: There was an increase in the frequency of DKA and severe DKA in children newly diagnosed with type 1 diabetes during the COVID-19 pandemic in 2020, with no apparent association with the severity of COVID-19 infection severity or containment measures. There has been a silent outbreak of DKA in children during the pandemic, and preventive action is required to prevent this phenomenon in the event of further generalized lockdowns or future outbreaks.

Increasing trend of type 1 diabetes incidence in the pediatric population of the Calabria region in 2019-2021.

BACKGROUND: Although type 1 diabetes (T1D) represents one of the most common chronic diseases in pediatric age, few studies on the epidemiology of T1D exist globally and the exact prevalence and incidence rates of the disease are unknown. In many countries, including Italy, national registries are missing. METHODS: This study aims to assess T1D incidence in the pediatric population of the Calabria region (southern Italy) in the period 2019-2021. The secondary objective was to describe the main demographical, clinical and immunological features of incident cases. Case ascertainment and all clinical data were assessed by retrospectively reviewing the electronic medical records of children and adolescents diagnosed with diabetes at any Pediatric Diabetes Center belonging to the Rete Diabetologica Calabrese (Calabria Region Diabetes Network), from January 2019 to December 2021. The incidence of T1D was estimated for the entire region and was stratified according to age group (0-4 years, 5-9 years, and 10-14 years) and gender. Standardized incidence ratios for each province in the region were also calculated. RESULTS: The crude incidence of T1D was 20.6/100,000 person/years. Incidence rates were higher among females and children aged 5-9 years. The crude incidence of T1D was higher in the province of Reggio Calabria (26.5/100,000 person-years). The provinces of Crotone, Catanzaro, and Vibo Valentia showed significantly lower standardized incidence ratios. The annual incidence in the region progressively increased by 43% during the study period. CONCLUSIONS: Our study revealed a relatively high incidence in the Calabria region. The marked increasing incidence trend over the past two years could be related to the global impact of the COVID-19 pandemic, but further long-scale population-based studies are needed to confirm these findings.

Prevention of type 1 diabetes: where we are and where we are going.

T1D (T1D) is one of the most frequent chronic disease in children and is associated to the risk of severe acute and chronic complications. There are about 550,000 children with T1D in the world; and about 86,000 children are diagnosed with T1D every year and its incidence is ever increasing. In this narrative review we will discuss current and future perspectives in T1D prevention strategies as well as their pitfalls. It is important to remember that for the first time one drug, in particular teplizumab (antibody anti-CD3) is going to be accepted for treatment in stage 2 of type 1 diabetes mellitus. This represent the onset of a new era.

Socioeconomic Inequalities Increase the Probability of Ketoacidosis at Diagnosis of Type 1 Diabetes: A 2014-2016 Nationwide Study of 2,679 Italian Children.

This study aims to compare the frequency of Diabetic Ketoacidosis (DKA) at diagnosis in 2014-2016 with the one previously reported in 2004-2013; and to assess the association between family socioeconomic status and DKA at type 1 diabetes (T1D) diagnosis in children <15 years of age from 2014 to 2016. Methods: This nationwide, population-based, observational study included 2,679 children diagnosed with T1D from 54 Italian centers for pediatric diabetes during 2014-2016. The ISPAD criteria for DKA were used as a standard reference. The overall and by age frequency of DKA between the two time periods were compared. The association between family socioeconomic status and DKA was assessed using multiple logistic regression analysis. Results: Nine hundred and eighty nine children had DKA (36.9, 95% CI: 35.1-38.8). The frequency of DKA was significantly lower in 2014-2016 in comparison to 2004-2013 (40.3, 95% CI: 39.3-41.4, p = 0.002). The probability of having DKA at diagnosis was lower in mothers with a high level of education (OR = 0.69, 95% CI: 0.51-0.93) or a high level of occupation (OR = 0.76, 95% CI: 0.58 0.99), and in fathers with a high level of occupation (OR = 0.72, 95% CI: 0.55-0.94). Children living in Southern Italy had a higher probability of diagnosis with severe DKA than children living in Central Italy. Conclusion: There was a decrease in the frequency of DKA in children diagnosed with T1D under 15 years of age during 2014-2016. However, DKA frequency remains unacceptably high. This study demonstrated that socioeconomic inequalities, measured as low education and occupational levels, were associated with an increased probability of DKA at T1D diagnosis.
