The prognostic role of microvascular complications (MVC) for all-cause death in patients with diabetes hospitalized for COVID-19 has been suggested. However, no detailed analysis of the microvascular burden is available so far. The CORONADO initiative is a French nationwide multicentre study of patients with diabetes hospitalized for COVID-19. The patients were enrolled after hospital admission from 03/10/2020 to 04/10/2020. MVC were defined as severe diabetic retinopathy (DR) and/or diabetic kidney disease (DKD, eGFR<60ml/min/1.73m2 and/or ACR>300mg/g) and/or diabetic foot ulcer (DFU). We analysed the association of MVC with death within 28 days after admission. The status for all 3 MVC was ascertained for 1755 participants including 1048 (60%) free of MVC. Patients with MVC were older, had lower BMI, HbA1c, AST/ALT concentration, lymphocyte and platelet counts, while sex, type of diabetes and CRP were not significantly different. Patients with any MVC had a sex- and age-adjusted OR for death of 2.54 (95%CI: 1.94-3.31, P<0.0001) compared to those without MVC. Figure details ORs for the different combinations of MVC. In patients with diabetes hospitalised for COVID-19, the microvascular burden associated with death within 28 days is dominated by DKD and DFU.
