Objective:
Type 2 diabetes mellitus (T2DM) is regarded as a chief risk factor for(coronavirus disease 2019 (COVID-19) owing to dysregulation of the expression of angiotensin-converting enzyme 2 (ACE2) and chronic low-grade inflammatory disorders. Metformin, an insulin-sensitizing agent for managing T2DM, has pleiotropic anti-inflammatory and oxidant potentials, which may lessen the risk of diabetic complications. So, we aimed to reveal the potential role of metformin monotherapy in treating T2DM patients with COVID-19.
Patients And Methods:
In this prospective cohort study, 60 hospitalized T2DM patients with COVID-19 on metformin plus standard anti-COVID-19 treatments compared to 40 hospitalized T2DM patients with COVID-19 on other diabetic pharmacotherapy like insulin and sulfonylurea, were recruited. Inflammatory and oxidative stress biomarkers and radiological and clinical outcomes were assessed at admission time and at the time of discharge.
Results:
The results of this study illustrated that metformin treatment in T2DM patients with COVID-19 was more effective in reducing inflammatory and oxidative stress biomarkers with significant amelioration of radiological scores and clinical outcomes compared to T2DM patients with COVID-19 on another diabetic pharmacotherapy.
Conclusions:
Our findings highlighted that metformin efficiently managed T2DM patients with COVID-19 by reducing inflammatory and oxidative stress with mitigating effects on the radiological scores and clinical outcomes.
