CRP and COVID-19: Moreover, as suggested by Zheng, Wu [97] and Al-kuraishy, Al-Gareeb [98], diabetes also induced the accumulation of ROS and pro-inflammation factors (oxygen saturation, serum ferritin, and C-reactive protein were 94.62%, 475.92 ng/mL, and 48.54 mg/L, respectively, in diabetic patients with COVID-19, whereas the values for these parameters were 98.99%, 90.51 ng/mL, and 3.16 mg/L, respectively, in healthy subjects with COVID-19), leading to lung injuries in individuals with diabetes, including an impaired respiratory system and interstitial lung injury.
