We assessed the expression of CD169, a type I interferon-inducible receptor, on monocytes (monocyte CD169 [mCD169]) in 53 adult patients admitted to the hospital during the coronavirus disease 2019 (COVID-19) outbreak for a suspicion of severe acute respiratory syndrome coronavirus 2 infection. Monocyte CD169 was strongly overexpressed in 30 of 32 (93.7%) confirmed COVID-19 cases, compared with 3 of 21 (14.3%) patients in whom the diagnosis of COVID-19 was finally ruled out. Monocyte CD169 was associated with the plasma interferon-alpha level and thrombocytopenia. Monocyte CD169 testing may be helpful for the rapid triage of suspected COVID-19 patients during an outbreak.
我们评估了 53 名在 2019 冠状病毒病(COVID-19)爆发期间因疑似严重急性呼吸综合征冠状病毒 2 感染而住院的成年患者单核细胞(单核细胞 CD169 [mCD169])上 CD169 的表达。与最终排除 COVID-19 诊断的 21 名患者中的 3 名(14.3%)相比,32 例确诊 COVID-19 病例中有 30 例(93.7%)强烈过表达 CD169。单核细胞 CD169 与血浆干扰素-α水平和血小板减少症有关。单核细胞 CD169 检测可能有助于在疫情爆发期间快速分诊疑似 COVID-19 患者。
