Common variable immunodeficiency (CVID) is the most common symptomatic primary immunodeficiency disease, predisposing the patients to various tissue involvement and organ damage. Here a 16-year-old boy is presented who was referred to our center with cough, dyspnea, cyanosis, and history of recurrent pneumonia. The diagnosis of CVID was made according to reduction all serum immunoglobulin level...

Common Variable Immunodeficiency Disorders (CVIDs) are the most prevalent cause of primary antibody failure. CVIDs are highly variable and a genetic causes have been identified in <5% of patients. Here, we performed whole genome sequencing (WGS) of 34 CVID patients (94% sporadic) and combined them with transcriptomic profiling (RNA-sequencing of B cells) from three patients and three healthy co...

This paper describes the first case of common variable immunodeficiency (CVID) and AA amyloidosis. A recently treated tuberculosis, and chronic inflammation induced by frequent respiratory tract infections, were thought to be responsible for the amyloidosis. No other reason for this condition could be detected. Although T cell dysfunction in some CVID patients has been reported, pulmonary tuber...

Common variable immune deficiency disease (CVID) is one of the most common primary immunodeficiency disorders. It causes reduction of immunoglobulin levels and specific antibodies production and enhancement of recurrent and chronic infections risk, especially respiratory infections and gastrointestinal tracts. Here, we report a case of CVID in a 3 years old male with recurrent hospitalizations ...

Background Common variable immunodeficiency (CVID) is one of the most common primary immunodeficiency in adults and is characterized by defective antibody production, low levels of serum immunoglobulins and increased susceptibility to infection. About 20% of developed different gastrointestinal pathology. But also the pathology of the gastrointestinal tract in patients with CVID showed a wide s...

Common variable immunodeficiency (CVID) is increasingly recognized for its association with autoimmune and inflammatory complications. Despite recent advances in immunophenotypic and genetic discovery, clinical care of CVID remains limited by our inability to accurately model risk for non-infectious disease development. Herein, we demonstrate the utility of unbiased network clustering as a nove...

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 (CVID) is characterized by low levels of circulating immunoglobulins, leading to frequent infections, particularly of the respiratory tract. Frequently, T-cell abnormalities are observed. Interleukin-7 (IL-7) is involved in the homeostasis of lymphocytes, and may be elevated in lymphopenia. Mutations of genes related to IL-7 may lead to severe immunodeficiency d...
