The many faces of the clinical picture of common variable immune deficiency

To summarize the recent advancements in common variable immune deficiency (CVID), specifically CVID genetics, clinical discoveries and treatment implications.

Large genomic studies have implicated new genes in the pathogenesis of CVID, and basic science studies have contributed to our knowledge of potential mechanisms. Cohort studies have further defined the immunologic parameters and clinical presentation of CVID, as well as the factors that contribute to morbidity and mortality in this disease. Immunoglobulin remains the mainstay of treatment, although there may be a role for immunosuppression and other therapies.

CVID is a genotypically and phenotypically heterogeneous primary immune deficiency, the genetic and clinical characteristics of which are under active investigation. Further, discovery may yield important new treatment protocols that can continue to reduce the morbidity and mortality from this disease.
