The COVID and Diabetes Assessment (CODA) study is for adults who have been diagnosed with type 1 diabetes or type 2 diabetes within the last 90 days. This study will examine if having a recent COVID-19 infection may impact the course of diabetes. We will gather information about both diabetes and COVID-19 infection. Participants will be followed for 2 years and asked to complete surveys and provide blood samples. No treatment or medications are involved in the study.

The protocol aims to improve standard of care, by ensuring an agile research infrastructure, with an ability to rapidly assess interventions during epidemic transmission of one or more respiratory pathogens adversely affecting public health.

Trials within this protocol can be adaptive, will be randomized, and will have superiority as the primary objective. Comparisons in the trials may be between an unlicensed agent to a blinded placebo plus standard of care (SOC), between an approved off-label agent to a blinded placebo plus SOC, among several active interventions (blinded or non-blinded; i.e., a comparative effectiveness study), or among different treatment strategies.

Persistent smell loss that can include diminished or distorted smell function is a common symptom of long COVID syndrome. There are limited treatment options for long COVID-related smell loss. Our study aims to determine the efficacy of two at-home treatments, smell training and non-invasive trigeminal nerve stimulation. This study requires participants to conduct daily at-home treatment sessions, attend three in-person study visits at the MUSC Department of Psychiatry and Behavioral Sciences, and complete electronic questionnaires over the 12-week trial, and again at the six-month timepoint. Participants in this trial may benefit directly with an improvement in sense of smell. However, participation may also help society more generally, as this study will provide new information about long COVID-related smell loss and its treatment.

Substudy

Long COVID syndrome has been associated with cognitive impairment and may be related to affected emotional regulation. This study will use a electroencephalography (EEG) to examine how the body and brain responses to emotional cues in participants who are currently undergoing treatment for COVID-related smell loss. Participation will aid in the understanding of how emotional processing in long COVID is impacted by treatment for related smell loss.

This is a low-interventional cohort study to determine cardiac and non-cardiac long-term outcomes of persons <21 years of age with myocarditis/pericarditis after the administration of COMIRNATY, compared with similarly aged persons with myocarditis/pericarditis associated with COVID-19, including MIS-C.
