Glycemic variability and time in range among children with type 1 diabetes on insulin pump during the Covid-19 pandemic in Egypt; single center experience

BACKGROUND: Covid-19 has impacted the lives of individuals worldwide especially those with chronic illnesses. Children with type 1 diabetes (T1DM) are at risk of glycemic deterioration during the Covid-19 pandemic. However, some studies reported glycemic improvement in these children during the pandemic. AIM: To assess the impact of Covid-19 on glycemic control and acute complications among children with T1DM on insulin pump in Egypt. METHODOLOGY: Forty-two children with T1DM on insulin pump for at least 1 year were assessed during the period from June 2020 to May 2021 for insulin requirements, insulin-pump problems, frequency of diabetic-ketoacidosis (DKA), hypoglycemia and HbA1C. Continuous-glucose monitoring was done using Medtronic i-pro device for 5 days. Data were compared to those obtained from the patients' medical records 1 year previously. RESULT: Upon comparing data during Covid-19 pandemic with previous data from 12-24 months before Covid-19, there was a significant small increase in the mean total daily insulin dose from 0.83 ± 0.28 to 0.88 ± 0.30 U/kg/day with a similar small increase in the mean basal percentage from 51.19 ± 3.46 to 52.74 ± 4.31. Interestingly, the median time in range showed small increase from 53 (IQR 47-61) to 57.0 (IQR 51-73), the mean coefficient of variation showed small decrease from 42.10 ± 9.90 to 38.20 ± 8.12 and the mean HbA1C significantly decreased from 8.8 ± 1.3 (72.31 ± 16.78 mmol/ml) to 7.8 ± 1.2 mg/dl (61.31 ± 16.62 mmol/mol). Twenty-nine children (69%) had insulin-pump problems in the form of skin irritation (31%), skin infection (7.1%) and pump Set/Site occlusion (31%). CONCLUSION: No safety issues and overall glycemic improvement were reported among the children with T1DM on insulin pump therapy from this single center during the covid-19 pandemic.
