We found no significant difference in LPS levels between CVID patients with serum IgA < 0.1 g/L compared to CVID patients with IgA ≥ 0.1 g/L, or CVID patients with or without autoimmune cytopenia, organ specific autoimmunity or enteropathy (Supplementary Table 6). This evidence concerns the gene CD79A and Autoimmunity.
