Insights
Poor glycemic control in diabetic patients with COVID-19 significantly increases the risk of severe disease and mortality. Maintaining good blood sugar levels is crucial for better outcomes in these patients.
Area of Science:
- Endocrinology
- Infectious Diseases
- Public Health
Background:
- Severe COVID-19 disproportionately affects patients with comorbidities like diabetes, hypertension, and cardiovascular disorders.
- Effective glycemic control is recognized as a key strategy to mitigate COVID-19 progression in diabetic individuals.
- The potential of glycemic status as an early predictive biomarker for COVID-19 severity in diabetic patients warrants investigation.
Purpose of the Study:
- To evaluate the association between glycemic control status and COVID-19 severity in diabetic patients.
- To determine if glycemic control can serve as a predictive biomarker for disease progression and mortality in diabetic COVID-19 patients.
Main Methods:
- A retrospective study involving 122 patients (40 with poor glycemic control, 40 with reasonable glycemic control, 42 without diabetes) was conducted.
- Patient data, including demographic, clinical, and biochemical parameters (e.g., HbA1c), were collected and analyzed.
- Groups were compared based on disease severity and mortality rates.
Main Results:
- A significant difference in disease severity was observed across groups (p < 0.001), with 72.5% of poorly controlled diabetics experiencing severe disease.
- Mortality rates also differed significantly (p = 0.008), with 17.5% of poorly controlled diabetics succumbing to the infection.
- Patients with reasonable glycemic control and those without diabetes showed considerably lower rates of severe disease and mortality.
Conclusions:
- Poor glycemic control is a significant indicator of increased disease severity and mortality in diabetic patients with COVID-19.
- Glycemic control status can effectively predict COVID-19 progression and outcomes in this patient population.
- Emphasizing optimal glycemic management is crucial for improving prognosis in diabetic individuals infected with SARS-CoV-2.
Objective:
Most patients with a severe COVID-19 infection have underlying diseases such as hypertension, cardiovascular disorders, and diabetes, and the mortality rate in these patients is higher than in other patients. Reasonable glycemic control is a practical approach to prevent the progression of COVID-19 in patients with diabetes. In this study, we aimed at demonstrating that glycemic control status can be used as a biomarker in predicting the severity of the disease in the early period in diabetic patients with COVID-19.
Patients And Methods:
Our retrospective study consisted of 122 patients who referred to Sinop Ayancik State Hospital between April 1, 2020, and April 1, 2021. 40 diabetic patients with poor glycemic control (HbA1C above 7), 40 diabetic patients with reasonable glycemic control (HgA1c below 7), and 42 patients without diabetes were included in the study. The patients' data included in the study were obtained by scanning the retrospective files. These patients' demographic characteristics, clinical features, age, gender, length of stay, hemogram, biochemical, hormonal parameters, HgA1c levels, and atherogenic indexes were calculated and recorded. Study groups were compared in terms of disease severity and mortality.
Results:
A statistically significant difference was found between mild/severe conditions (p-value < 0.001). 72.5% of those with poor glycemic control, 57.5% of those with reasonable glycemic control, and 26.2% without diabetes had severe diseases. Also, a statistically significant difference was found between the distributions of death rate (p = 0.008). 17.5% of those with poor glycemic control, 5% of those with reasonable glycemic control, and 0% of patients without diabetes died.
Conclusions:
Our results showed that poor glycemic control was an effective indicator of disease severity and mortality in patients with COVID-19 and could predict disease progression and mortality.
