Interpretation. These data show that systemic IgA and IgG production against SARS- CoV-2 develops mainly in severe COVID-19, with very high IgA levels seen in patients with severe ARDS, whereas mild disease may be associated with transient serum titers of SARS-CoV-2-specific antibodies but stimulate mucos Interpretation. These data show that systemic IgA and IgG production against SARS- CoV-2 develops mainly in severe COVID-19, with very high IgA levels seen in patients with severe ARDS, whereas mild disease may be associated with transient serum titers of SARS-CoV-2-specific antibodies but stimulate mucosal SARS-CoV-2-specific IgA secretion. The findings suggest four grades of antibody responses dependent on COVID-19 severity. y.
De menar att det finns fyra olika nivåer av sjukdom, som dels har olika symptombild men också helt olika antikroppssvar:
1. Asymptomatisk med endast IgA antikroppar i näsa.
2. Mild sjukdom med kortlivade antikroppar i blod.
3. Svår sjukdom med hög nivå av antikroppar i blod.
4. Mycket svår sjukdom (ARDS) med extremt hög nivå av antikroppar i blod.
