Advances in the Phenotyping and Management of Common Variable Immunodeficiency.

This article highlights advances in the phenotyping and management of common variable immunodeficiency (CVID). Advances in phenotyping include the use of cell-based, soluble, and genetic profiling, combined with novel applications like machine learning, to better define high-risk (complicated CVID) and low-risk (uncomplicated CVID) patient populations. Advances in management include first-in-class clinical trials to treat noninfectious disease manifestations based on convergent pathways of immune dysregulation in CVID.
