Abstract

Abstract
Primary antibody deficiencies (PADs) are frequent primary immunodeficiencies in humans, characterized by hypogammaglobulinemia, defects in production of specific antibodies, and recurrent infections. Information about PADs is quickly developing, leading to improved diagnoses and efficient disease management. This study is a review of the pathogenesis, diagnosis, clinical manifestations, and management of PAD disorders such as agammaglobulinemia, common variable immunodeficiency, monogenic defects associated with hypogammaglobulinemia, class switch recombination deficiencies, selective IgA deficiency, subclass immunoglobulin isotypes deficiencies, specific antibody deficiency, and transient hypogammaglobulinemia.
