Insights
Patients with diabetes face severe outcomes and higher mortality from COVID-19 due to factors like hyperglycemia and immune dysfunction. This summary offers guidance for managing diabetes during the pandemic.
Area of Science:
- Endocrinology
- Infectious Diseases
- Public Health
Background:
- Diabetes mellitus is linked to worse outcomes and increased mortality in COVID-19 patients.
- Potential mechanisms include hyperglycemia, immune compromise, inflammation, comorbidities, and ACE2 signaling.
Purpose of the Study:
- To inform the diabetes medical community about COVID-19's impact on diabetic patients.
- To provide guidance for managing diabetes during the COVID-19 pandemic.
Main Methods:
- Review of existing literature on diabetes and COVID-19.
- Analysis of potential pathophysiological links.
- Compilation of recommendations from the Korean Diabetes Association.
Main Results:
- Uncontrolled hyperglycemia and other factors exacerbate COVID-19 severity in diabetic individuals.
- The Korean Diabetes Association offers specific management strategies for these patients.
Conclusions:
- Urgent awareness and careful management are crucial for diabetic patients during the COVID-19 pandemic.
- The provided guidance assists healthcare professionals in optimizing care for this vulnerable population.
Abstract:
Diabetes has been associated with more severe outcomes and higher mortality in coronavirus disease 2019 (COVID-19) patients compare to morbidity and mortality in patients without diabetes. Several mechanisms may play a role in this greater morbidity and mortality, especially uncontrolled hyperglycemia, an impaired immune system, pre-existing proinflammatory states, multiple comorbidities, and dysregulated angiotensin-converting enzyme 2 signaling. Thus, the diabetes medical community emergently needs to know about COVID-19 and its effects on patients with diabetes, as they must take precautions to carefully manage these patients during the COVID-19 pandemic. The Korean Diabetes Association provides some guidance and practical recommendations for the management of diabetes during the pandemic. This report provides insight into the association between diabetes and COVID-19, proper management of diabetes in patients with COVID-19 and an official suggestion by the Korean Diabetes Association for managing the COVID-19 outbreak.
