title: Antibody immunodeficiency diseases.
abstract: Among primary immunodeficiencies, antibody deficiencies are the most common. Patients often are examined first by multiple medical providers by whom the diagnosis may be missed or delayed, because signs and symptoms are usually sinopulmonary in origin, simulate common respiratory infections or respiratory allergies, and are usually responsive to symptomatic antimicrobial treatment. Because these diseases can be treated effectively, it is important to recognize them before complications occur. We have provided updated information on the more common antibody deficiency syndromes, their diagnostic assessment, and advances in treatment.
