使用免疫荧光抗体检测连续检测 30 名 SARS 患者的 IgG、IgM 和 IgA 血清水平,以对抗严重急性呼吸窘迫综合征 (SARS) 相关冠状病毒 (SARS-CoV)。 IgG 的血清转化(平均 10 天)同时发生,或者比 IgM 和 IgA 的血清转化早 1 天(两者平均 11 天)。最早在发病后 4 天即可检测到 IgG。这三种抗体达到峰值水平的最早时间相似(平均 15 天)。高 IgG 水平 (1:800) 可能持续 > 3 个月。在 5 名 SARS 患者中,用 100 倍 SARS-CoV TW1 株组织培养感染剂量 (TCID50) 获得的中和抗体动力学几乎与 IgG 相似。有或没有基础疾病、类固醇或静脉注射免疫球蛋白治疗或机械通气的患者之间的 IgG、IgM 和 IgA 反应动力学没有显着差异。
Serum levels of IgG, IgM and IgA against severe acute respiratory distress syndrome (SARS)‐associated coronavirus (SARS‐CoV) were detected serially with the use of immunofluorescent antibody assays in 30 patients with SARS. Seroconversion for IgG (mean 10 days) occurred simultaneously, or 1 day earlier, than that for IgM and IgA (mean 11 days for both). IgG could be detected as early as 4 days after the onset of illness. The earliest time at which these three antibodies reached peak levels was similar (mean 15 days). A high IgG level (1:800) could persist for > 3 months. The kinetics of neutralisation antibodies obtained with 100× the tissue culture infective dose (TCID50) of the SARS‐CoV TW1 strain in five patients with SARS nearly paralleled those for IgG. There were no significant differences in the kinetics of the IgG, IgM and IgA responses between patients with or without underlying medical disease, steroid or intravenous immunoglobulin therapy, or mechanical ventilation.
