Comparison of pulmonary diseases in common variable immunodeficiency and X-linked agammaglobulinaemia.

Unlabelled: Patients with CVID are at greater risk of developing lung complications than patients with XLA because of delayed diagnosis and possible immune dysregulation. Early diagnosis and appropriate treatment reduces the incidence of pulmonary infections in both groups of patients. However, CVID patients are prone to progressive lung disease despite optimal immunoglobulin therapy.
