Department of Immunology, School of Medicine, Isfahan University of Medical Sciences, Isfahan, Iran



Autoimmunity is observed by almost one-third of patients with CVID. Different mechanisms including genetic defects and dysregulation of innate and adaptive immunity leads to autoimmunity in these patients CVID. The clinical phenotypes of autoimmunity in CVID patients comprise fall in a wide spectrum, from organ-specific autoimmunity to systemic complications. The most common autoimmunity is autoimmune cytopenia in CVID patients. In this article, we have provided a collection of the most significant and recent information about prevalence, genetics, pathogenesis and clinical manifestations of autoimmunity in CVID patients, and provided an overview on its management and future perspective.
