Aims: One of the most dangerous complications of COVID-19 is sudden hyperglycemia that may carry a high incidence of the death rate. This study aimed to evaluate the relationship between death rate and hyperglycemia caused by COVID-19 infection in non-diabetic patients.
Materials & Methods: In this study, 296 patients were selected randomly, 57 patients complaining of sudden hyperglycemia (>400 mg/dl) one week after the high fever subsided; the others did not show such complain. Statistical analysis was done to evaluate the relative risk of hyperglycemia upon the incidence of mortality rate between two groups.
Findings: The X2 value was 20.5959 for all, and the p-value was not significant except for COVID-19 with hyperglycemia that showed a highly significant mortality rate (X2=15.9, p<0.001).
Conclusion: Hyperglycemia should be monitored even after regression of COVID-19 symptoms, and insulin therapy must be considered to minimize the risk of death.
