Common Variable Immunodeficiency: A Paradox of Immunodeficiency and Autoimmunity

Abstract

Common variable immunodeficiency disorders (CVID) are the most common form of symptomatic primary immunodeficiency. The diagnosis of CVID can be challenging as the symptoms are non-specific and heterogenous in nature. In light of this, a broad review of this disease is presented here based on the important clinical symptoms, complications and management.
