T-cell abnormalities in common variable immunodeficiency: the hidden defect

This review discusses how the T-cell compartment in common variable immunodeficiency is marked by the premature arrest in thymic output, leading to T-cell exhaustion and immune dysregulation. Although B cells have been the main focus of the disorder, ample experimental data suggest that T-cell abnormalities can be seen in a large proportion of Freiburg Group 1a patients and those suffering from...

Common variable immunodeficiency. Old questions are getting clearer.

Common variable immunodeficiency (CVID) is a heterogeneous entity characterized by an impaired ability to produce antibodies. The failure is localized in partially mature B lymphocytes, though T lymphocyte abnormalities are occasionally present. This deficiency affects antibody synthesis and class switch from IgD and IgM, to IgG and IgA. CVID is related to selective IgA deficiency, and both abn...

T and B lymphocyte abnormalities in bone marrow biopsies of common variable immunodeficiency.

In common variable immunodeficiency (CVID) defects in early stages of B-cell development, bone marrow (BM) plasma cells and T lymphocytes have not been studied systematically. Here we report the first morphologic and flow cytometric study of B- and T-cell populations in CVID BM biopsies and aspirates. Whereas the hematopoietic compartment showed no major lineage abnormalities, analysis of the l...

Evaluation of TH17 profile in common variable immunodeficiency patients with or without autoimmunity

Background Common Variable Immunodeficiency (CVID) is the most common symptomatic primary antibody deficiency in clinical practice and it is characterized by hypogammaglobulinemia, increased susceptibility to infections, autoimmune diseases and malignancies. The pathogenesis of CVID is still not well established. Immunologic abnormalities found in CVID patients include defects in B cell differe...

Characterization of common variable immunodeficiency: identification of a subset of patients with distinctive immunophenotypic and clinical features.

The peripheral blood lymphocyte surface markers and clinical features of 38 patients with common variable immunodeficiency (CVID) were assessed. These studies identified a subset of CVID consisting of 14 of the 38 patients with a distinctive T-cell immunophenotype and clinical findings. The phenotypic changes were characterized by an abnormally low CD4/CD8 ratio (less than or equal to 0.9) due ...

A CASE REPORT OF COMMON VARIABLE IMMUNODEFICIENCY(CV ID) WITH LEUKOCYTES ADHESION DISORDERS (LADS)

A three year old boy with delayed separation of the umbilical cord, recurrent pyogenic infections and common variable immundeficiency is presented. The immunoglobulin measurement was severely abnormal. To the best of our knowledge, the existance of leukocyte adhesion disorder together with common variable immunodeficiency (CYID) in a patient has not been reported prior to this study.
