SUBCUTANEOUS INSULIN ASPART EVERY 4 HOURS IN THE TREATMENT OF COVID-19 PATIENTS WITH DIABETIC KETOACIDOSIS: A RETROSPECTIVE STUDY Introduction: COVID-19 infection increases the risk of diabetic ketoacidosis (DKA). To limit the healthcare workers’ exposure when taking care of the COVID-19 patients, treatment of DKA with subcutaneous (SC) rapid-acting insulin analogs every 4 hours was suggested in many professional recommendations. However, the evidence to support this strategy is lacking. We aimed to report the efficacy and safety of SC insulin aspart every 4 hours in the management of DKA in COVID-19 patients. Methods: We retrospectively reviewed all confirmed COVID-19 patients aged >15 years who developed mild-moderate DKA between July 2020 and October 2021 in our institution. Insulin aspart was delivered 0.4 units/kg SC every 4 hours. When blood glucose (BG) decreased to <250 mg/dL, the dose of insulin aspart was reduced to 0.2 units/kg every 4 hours until resolution of DKA. SC Basal insulin 0.15-0.2 units/kg was also initiated at the time of DKA diagnosis. Result: A total of 7 patients had mean age of 67.43±13.19 years with body mass index of 25.49±3.42 kg/m(2). Most was 71.4% of female and all had pre-existing type 2 diabetes mellitus. All patients received high-dose steroid for COVID-19 treatment. Initial biochemical parameters were BG of 449±157.3 mg/dL, hemoglobin A1c of 10.58±2.81%, pH of 7.34±0.07, beta-hydroxybutyrate of 4.0±1.51 mmol/L, and HCO(3) of 15.5±2.17 mmol/L. Time to resolution of DKA were 12.7±5.82 hours. Conclusion: From our cohort, SC rapid-acting insulin administered every 4 hours could be applied in the selected COVID-19 patients with mild-moderate DKA. Presentation: Thursday, June 15, 2023
