COVID-19 and diabetes: Insulin requirements parallel illness severity in critically unwell patients

Clinical Endocrinology

Abstract

In the light of increased adverse outcomes for people with diabetes affected by COVID-19, we have described the clinical course of a cohort of critically ill patients with COVID-19 and diabetes. We retrospectively analysed characteristics, glucometrics and inflammatory markers of patients with diabetes mellitus admitted to intensive care unit (ICU) with COVID-19. Eight patients with diabetes were admitted to ICU with COVID-19. All had type 2 diabetes, with three being newly diagnosed that admission. Mean HbA1c was 9.2%. Glucometric analysis indicated that extremely high insulin doses were required during peak inflammatory response to maintain glycaemic control with a mean peak insulin requirement of 201 units per day (2.2 units/kg/day). Critically unwell patients with diabetes mellitus and COVID-19 had high insulin requirements and poorer time in target range at the time of peak inflammatory response, and this improved as their illness resolved.

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
