Primary immunoglobulin deficiency and haematological disorders.

Nine patients with immunoglobulin deficiency and various haematological disorders are presented. In all patients, recurrent infections had antedated the onset of the haematological disorder but, in most, the possibility of primary immunodeficiency had not been considered until after the haematological diagnosis had been established. The recognition of immunodeficiency is important since such patients may require steroids, immunosuppressive therapy or splenectomy. Gammaglobulin would appear to be the appropriate therapy in this situation. Infections were reduced in all 6 patients so treated.
