Impacts of diabetes mellitus on COVID-19: a literature review
Keywords:
Pandemic, COVID-19, SARS-CoV-2, Diabetes Complication, Respiratory Distress SyndromeAbstract
Introduction:
Since the beginning of the pandemic, the correlation between diabetes mellitus and the worsening of COVID-19 cases has been evaluated, since patients with diabetes mellitus infected with SARS-CoV-2 have high hospitalization rate, severe pneumonia and higher mortality. Objectives: The study sought to understand and verify the correlation of diabetes mellitus with the aggravating outcomes of COVID-19. Methods: A narrative literature review was carried out through exploratory and selective reading of articles and, finally, the recording of relevant information. The PUBMED and Google Scholar databases were used as research source, between 2000 and 2022, with the keywords: diabetes mellitus, COVID-19, COVID-19 pandemic, SARS-CoV-2 infection, SARS-CoV-2, COVID-19 viral infection, middle east respiratory syndrome coronavirus, human SRDA. Results and discussion: The articles showed that the association between diabetes mellitus and COVID-19 leads to a twofold increased risk in both mortality and severity of COVID-19. In addition, in diabetes mellitus there is a development in complications such as: endothelial and alveolar dysfunction, hypercoagulation, as well as a dysregulated immune response that contribute to serious outcomes. Conclusion: Diabetes mellitus contributes to a poor prognosis and aggravating outcomes of COVID-19 cases, however studies are needed to elucidate the mechanisms associated with these diseases.
