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 children&a...

Objective: TCR (T Cell Receptor) which is expressed on T cells responsible for recognizing antigens presented by HLA molecules of the APCs (Antigen Presenting Cells) and initiation immune response. It has been reported that TACI (Transmembrane activator calcium modulating cyclophilin ligand interactor) mediates interaction B dendritic are both processing cells. Materials Methods: In this study,...

Common variable immunodeficiency disorder (CVID) is the commonest cause of primary antibody failure in adults and children, and characterized clinically by recurrent bacterial infections and autoimmune manifestations. Several innate immune defects have been described in CVID, but no study has yet investigated the frequency, phenotype or function of the key regulatory cell population, natural ki...

Recent data suggest a critical role for dendritic cells (DCs) in the generation of immunoglobulin-secreting plasma cells. In the work reported herein, we analyzed the frequency of peripheral blood plasmacytoid DCs (pDCs) and myeloid DCs (mDCs) in a cohort of 44 adults with common variable immunodeficiency (CVID) classified according to their CD27 membrane expression status on B cells. A deep al...

An unusual combination of common variable immunodeficiency (CVID) and Turner's syndrome in a Saudi woman aged 20 years is presented. In addition to panhypogammaglobulinaemia, the patient had CD4+ T lymphocytopenia; however, there was evidence of in vivo activation of T cells and overproduction of soluble interleukin 2 receptor in culture supernate. Mantoux test was positive, but lymphoblastic r...

Common variable immunodeficiency (CVID) is a heterogeneous group of diseases. Our aim was to define sub-groups of CVID patients with similar phenotypes and clinical characteristics. Using eight-color flow cytometry, we analyzed both B- and T-cell phenotypes in a cohort of 88 CVID patients and 48 healthy donors. A hierarchical clustering of probability binning "bins" yielded a separate cluster o...

BACKGROUND Common variable immunodeficiency (CVID) is characterised by hypogammaglobulinaemia and a broad clinical spectrum, mainly showing recurrent bacterial infections accompanied sometimes by increased susceptibility to chronic lung disease, autoimmunity, and neoplastic diseases. OBJECTIVES To evaluate the clinical and immunological characteristics of patients with CVID in Mexico. METHO...

BACKGROUND Common variable immunodeficiency (CVID) is a very heterogeneous syndrome defined by impaired immunoglobulin production. The primary defect remains unknown, but many reports describe peripheral blood T and B lymphocyte dysfunctions in a substantial proportion of CVID patients. Immunophenotypic alterations on memory B lymphocytes correlate with clinical findings. A B-cell-oriented clas...

OBJECTIVES Complementary and alternative medicine (CAM) usage is a reality in patients with chronic diseases, but there are no data on CAM usage in immunodeficiency diseases necessitating intravenous immunoglobulin (IVIG) therapy.The aim of this study was to investigate the rate of CAM usage in patients with common variable immunodeficiency (CVID). METHODS Forty-three patients (29 boys and 14...
