ABSTRACT
INTRODUCTION:
Autoimmunity is a common feature in CVID patients. To date the mechanisms leading to the development of such complications are not fully elucidated. MATERIALS ANDMETHODS:
Data from 122 CVID patients subdivided in three groups based on the absence of autoimmunity (n-AI) or the presence of hematologic autoimmune phenomena (Cy-AI) or non-hematologic autoimmune phenomena (n-Cy-AI) were evaluated.RESULTS:
We identified a total of 128 autoimmune manifestations in 55/122 patients (45.1%). 30/122 (24.6%) patients presented hematologic autoimmune phenomena while 29/122 (23.8%) presented gastrointestinal autoimmune involvement. Immune thrombocytopenia was the most common manifestation (27/122; 22.1%), followed by autoimmune hemolytic anemia (18/122; 14.8%) and autoimmune enteropathy (17/122; 13.9%). Cy-AI patients displayed higher CD4+ effector memory and terminally differentiated CD8+ cells with lower percentages of naïve and recent thymic emigrants (RTEs) CD4+ cells and a significant expansion of the CD19hiCD21low population.CONCLUSIONS:
CVID patients developing autoimmune cytopenias display characteristic immune phenotypic features.Palabras clave
