Abstract

Long-term sequelae of severe acute respiratory coronavirus-2 (SARS-CoV-2) infection may include an increased incidence of diabetes. Our objective was to describe the temporal relationship between new diagnoses of diabetes mellitus and SARS-CoV-2 infection in a nationally representative database. There appears to be a sharp increase in diabetes diagnoses in the 30 days surrounding SARS-CoV-2 infection, followed by a decrease in new diagnoses in the post-acute period, up to 360 days after infection. These results underscore the need for further investigation, as understanding the timing of new diabetes onset after COVID-19 has implications regarding potential etiology and screening and treatment strategies.

Figures

Figure 1:
Figure 1:. Among all persons with diabetes in the database, the proportion of diabetes cases that were diagnosed between Sept 2019 and February 2022, by 30-day periods relative to infection with SARS-CoV-2.
This plot represents the proportion of diabetes cases in the N3C database that were diagnosed after September 2019 in persons who did not have a previous diagnosis of diabetes. Each line represents a calendar month of the pandemic. The Y axis is the proportion of all persons with SARS-CoV-2 and a DM diagnosis who received the ICD code for DM after September 2019, and the temporal relationship between the diagnoses between 180 days prior to 360 days after the SARS-Co-V-2 infection. The large peak between 8 days before and 30 days after is represented in an inset so that the top of that peak is visible without compressing the Y axis.
Figure 2:
Figure 2:. Number of new diabetes mellitus (DM) cases within 180 before and 360 days after SARS-CoV-2 infection, among individuals who have both EHR-recorded SARS-CoV-2 infection and ICD code for DM and did not have an ICD code for DM before September 2019.
Each line represents a calendar month during the pandemic; the Y axis is the number of new DM cases in the N3C database in persons with a documented SARS-CoV-2 infection. The x-axis is temporal relationship between the diabetes diagnosis relative to each individual’s SARS-CoV-2 infection.
