CD79A and infection: Considering the anti-microbial antibodies individually, both the presence (OR: 1.73, 95% CI: 1.02–2.92, p = 0.041) and the type of ASCA positivity (not positive: 24.4%, IgA- or IgG- positive: 30.8%, IgA- and IgG-positive: 43.8%, p = 0.015 by linear-by-linear association) were associated with the development of severe infections.
