| dc.description.abstractEn | The pathogenesis of life-threatening coronavirus disease 2019 (COVID-19) pneumonia in ICU patients can involve pre-existing auto-antibodies (auto-Abs) neutralizing type I interferons (IFNs). The impact of these auto-Abs on SARS-CoV-2 clearance in the lower respiratory tract (LRT) is unclear. We performed a retrospective study in 99 ICU patients with COVID-19 pneumonia between March and May 2020. LRT SARS-CoV-2 load (intensity and duration) was analyzed according to the presence or not of circulating auto-Abs neutralizing type I IFNs. Among the 99 included patients, 38 (38%) were positive for auto-Abs neutralizing type I IFNs, with 5 (5%) harboring auto-Abs neutralizing IFN-α2 at any concentration, while 33 (33%) had auto-Abs neutralizing only IFN-ω at the lower concentration. SARS-CoV-2 load in the LRT and duration of viral shedding, were similar in patients with or without auto-Abs neutralizing type I IFNs. Patients with auto-Abs had the same mortality than those without auto-Abs, despite greater occurrence of renal failure and ECMO support, and longer duration of mechanical ventilation and ICU stay. In summary, 5% of patients with critical COVID-19 pneumonia carried auto-Abs neutralizing IFN-α2, while about 1/3 harbored auto-Abs neutralizing low concentrations of IFN-ω. The detection of either type of auto-Abs did not impact LRT viral clearance and mortality, although it was associated with greater morbidity and a longer hospitalization. These findings suggest that similar albeit hitherto unknown mechanisms of disease drive critical COVID-19 pneumonia in patients without auto-Abs against type I IFNs. | |
