CD79A and common variable immunodeficiency: Cytokine analyses of CVID patients with serum IgA < 0.1 g/L compared to CVID patients with IgA ≥ 0.1 g/L showed increased concentrations of two chemokines involved in inflammatory processes (i.e., IP-10 and MCP-1) in patients with IgA < 0.1 g/L, but did not display an overall different pattern in cytokine levels than those with IgA ≥ 0.1 g/L (Supplementary Table 8).
