Filter by:The purpose of this study is to discover if differences in the surface markers of B-cells (antibody producing cells of the immune system) in Common Variable Immune Deficiency (CVID) are related to CVID or its complications/treatment (e.g. bronchiectasis, granulomatous disease, immunoglobulin treatment). The study hypothesis is that the altered B-cell surface markers are related to CVID, and not to the complications or treatment of CVID.
