Clinical presentation and outcome of COVID-19 infection in Type 2 Diabetes Mellitus: a preliminary data from a tertiary hospital in Jakarta during the early days of the pandemic

Abstract

Introduction. This study aimed to review the clinical characteristics and outcomes of COVID-19 patients presented with in-hospital hyperglycemia or pre-existing type 2 diabetes (T2DM).Methods. This is a retrospective study conducted in Fatmawati General Hospital, Indonesia, from March 18th-Apr 30th, 2020. We reviewed medical records of 27 COVID-19 patients presented with either in-hospital hyperglycemia (11, 12.2%) or pre-existing T2DM (16, 17.8%) from a total of 90 confirmed COVID-19 cases admitted in our hospital.Results. Critical conditions occurred in 50% of T2DM and 54.55% of the in-hospital hyperglycemia group. Mortality was documented in 68.75% of T2DM and 81.82% of in-hospital hyperglycemia group. Hypoglycemia, diabetic ketoacidosis, lactic acidosis and ketosis were found in 12.5%, 25%, 18.75%, and 25% of individuals with T2DM, respectively, resulting in a high mortality rate. Meanwhile, diabetes-related complications were rare among the in-hospital hyperglycemia group. However, respiratory failure (45.45% vs. 6.25%) and septic shock (27.27% vs. 6.25%) were more frequent than in the T2DM group.Conclusion. In this preliminary study, a high mortality rate was documented among COVID-19 patients with preexisting T2DM and in-hospital hyperglycemia. In T2DM subjects, diabetes related-complications contributed to a higher mortality rate, while in-hospital hyperglycemia group, respiratory failure and septic shock were more frequent.
