The occurrence of either individual anti-microbial antibodies or multiple seropositivity was associated with the presence of ascites (ORASCA either: 1.93, 95% CI: 1.19–3.14; ORanti-OMP PlusTM: 3.08, 95% CI: 1.86–5.11) (see Table 4) as well as the quantitative anti-OMP PlusTM IgA serological response (median, no ascites vs. ascites: 25.4 vs. 41.5 Units, p<0.001). Here, CD79A is linked to Ascites.
