Increased heme levels, anemia, and desaturation occur during infection. We aimed to compare the levels of heme, heme oxygenase-1 (HO-1), ferritin, and bilirubin in coronavirus disease 2019 (COVID-19) patients at different saturation levels. Heme and HO-1 enzyme levels significantly increased in the low SpO₂ group, but further studies are required.

COVID-19感染期间的去饱和和血红素升高：血红素加氧酶-1的潜在预后因素

感染期间血红素水平升高，贫血和脱饱和。我们旨在比较不同饱和度水平下的冠状病毒病2019（COVID-19）患者中血红素，血红素加氧酶-1（HO-1），铁蛋白和胆红素的水平。低SpO ₂组的血红素和HO-1酶水平显着增加，但需要进一步研究。
