Abstract

Objective: Since December 2019, coronavirus disease 2019 (COVID-19) emerged in Wuhan city and has become a pandemic. Many affected patients had mild symptoms, while some people had severe symptoms or died. Uncontrolled diabetes tends to be one of poor prognostic factor in many studies1-3 This study aimed to examine the relationship between HbA1c levels and the severity of COVID-19 patients in Nakhonpathom Hospital

Methods: A single-center, retrospective observational study was conducted. Baseline characteristics; blood chemistry; and severity parameters such as chest x-ray, oxygen saturation, and patient outcomes were collected

Results: Since May to September 2022, 595 COVID-19 patients with diabetes mellitus were included. Of total, 29.3% of patients were newly diagnosed of diabetes mellitus. We compared between severe group (patients who required oxygen support, SpO2 ≤94%, or disease progression or dead) and non-severe group and correlation analysis was performed. The effect between higher body weight and severity of COVID-19 increased significantly (Mean ± SD 69.97 ± 17.54 vs 75.06 ± 20.75; p = .03). However, higher HbA1c level, blood sugar, and BMI related insignificantly with COVID-19 severity

Conclusion: The correlation between high HbA1c and severity of COVID-19 is still inhomogeneous. Our study demonstrates that patients with high HbA1c was insignificant relate to severe COVID-19.
