Has the COVID-19 Pandemic Affected the Prevalence of Diabetic Ketoacidosis in Polish Children with Newly Diagnosed Type 1 Diabetes? An Example of the Largest Polish Pediatric Diabetes Center (Upper Silesia-Katowice, Poland).

PURPOSE

The aim of this study was to analyze the prevalence of diabetic ketoacidosis (DKA) in children with newly disclosed type 1 diabetes (T1D) during the COVID-19 pandemic in 2020 compared to 2019.

METHODS

A retrospective analysis of the history database of all hospitalized children in our department. The International Society for Pediatric and Adolescent Diabetes (ISPAD) guidelines were used for the diagnosis of DKA.

RESULTS

The database of children with newly disclosed T1D included 196 patients (89 girls and 107 boys) from 2019, and 223 patients (113 girls and 110 boys) from 2020 (a total of 419 patients-202 girls and 217 boys) aged 0 to 18 years. A significantly higher percentage of DKA was observed in 2020 compared to the previous year (47.53% vs. 35.2% [ = 0.005]). The percentage of severe DKA increased in 2020 compared to 2019 (18.39% vs. 14.07% [ = 0.118]). Compared to 2019, the average HbA1c level was higher in 2020 (12.57 ± 2.75% vs. 11.95 ± 2.89% [ < 0.025]), and the average pH level (7.26 vs. 7.31 [ = 0.002], and average HCO3 level (16.40 vs. 18.66 [ = 0.001]) were lower, respectively.

CONCLUSIONS

During the COVID-19 (2020) pandemic, the incidence of DKA increased in Polish children with newly diagnosed T1D. The conclusions from the analysis of the functioning of health systems during the pandemic should be used in the future to prevent, in similar periods, an increase in severe complications of delayed diagnosis of T1D.
