Abnormal interleukin-7 function in common variable immunodeficiency.

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.

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 20-YEAR SURVEY OF INFECTIOUS COMPLICATIONS IN 64 PATIENTS WITH COMMON VARIABLE IMMUNODEFICIENCY

Common variable immunodeficiency (CV ID) is a heterogeneous primary immunodeficiency disorder, characterized by hypogammaglobulinemia and increased susceptibility to recurrent bacterial infections. To determine the spectrum of infectious complications in patients with common variable immunodeficiency (CV ID), we reviewed the hospital records of 64 CVID patients, who were diagnosed in Child...

Co-existence of Common Variable Immunodeficiency (CVID) with Idiopathic Thrombocytopenic purpura (ITP)

Novel function for interleukin-7 in dendritic cell development.

Interleukin-7 (IL-7) is crucial for the development of T and B lymphocytes from common lymphoid progenitors (CLPs) and for the maintenance of mature T lymphocytes. Its in vivo role for dendritic cells (DCs) has been poorly defined. Here, we investigated whether IL-7 is important for the development or maintenance of different DC types. Bone marrow-derived DCs expressed the IL-7 receptor (IL-7R)...
