Abstract

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…
