Hyperglycemia as a metabolic factor associated with death from COVID 19
Keywords:
biomarkers, COVID-19, hyperglycemiaAbstract
Introduction: COVID-19 most frequently affects adults with comorbidities and risk factors that promote a proinflammatory state. Hyperglycemia is among the factors most frequently associated with severity.
Objective: To epidemiologically and humorally characterize the deaths of diabetic and non-diabetic patients with COVID-19 who had abnormalities in baseline blood glucose levels upon admission.
Methods: A cross-sectional, analytical study was conducted from March 2020 to January 2022, including 309 deceased patients. The following variables were included: age, sex, previous diagnosis of diabetes mellitus, presence of other comorbidities, clinical presentation, hospital stay, and clinical laboratory variables. Descriptive statistics and chi-square tests were applied.
Results: Altered baseline blood glucose levels were primarily associated with age over 60 years (55.5% vs. 62.5%), respiratory symptoms (90.5% vs. 65.1%), and having three or more comorbidities (61.5% vs. 56.7%). In diabetic patients, a personal medical history and abnormal laboratory parameters predominated, while in non-diabetic patients, prolonged hospital stays and delays in seeking medical care were more common.
Conclusions: Patients who died from COVID-19 and had abnormal baseline blood glucose levels on admission were characterized by older age, respiratory symptoms, and multiple comorbidities.
