BACKGROUND Common variable immunodeficiency (CVID) is a primary immunodeficiency disease characterized by recurrent infections and increased susceptibility to autoimmunity and malignancy. OBJECTIVES This study was performed to estimate the burden of CVID in Iran during 1985-2008 based on incidence, mortality, and disability-adjusted life-years (DALY). METHODS The methods developed by the Wo...

Common variable immunodeficiency (CVID) is one of the most common and clinically important primary immune deficiencies. CVID patients have poor humoral immunity, resulting in recurrent infections of the gastrointestinal and upper respiratory tracts, as well as increased incidence of some forms of cancers and autoimmune diseases. The treatment for CVID is IgG replacement, often given as intraven...

BACKGROUND We describe the first case of a patient with factitious disorder who closely simulated a primary immune deficiency disorder - Common Variable Immune Deficiency (CVID), by surreptitiously ingesting non-steroidal anti-inflammatory agents. CASE DESCRIPTION He was treated with several expensive and potentially dangerous drugs before the diagnosis was established through collateral info...

Background: Patients with unclassified hypogammaglobulinemia (UCH) constitute a diagnostic and therapeutic dilemma, because information concerning the clinical and immunological characteristics of these patients is insufficient. Objective: To evaluate B-cell subsets in cases with UCH and common variable immunodeficiency (CVID) and their association with treatment requirement in UCH patients. Me...

common variable immunodeficiency (cvid) is a heterogeneous heritable disease characterized by arrest in b cell differentiation. an association between cvid and two hla haplotypes, haplotype i (hla-a1, hla-b8, hla-dr3) and haplotype ii (hla-a29, hla-b44, hladr7)has been previously documented. in the present study, we have attempted to find an association between susceptibility to cvid and hla cl...

Common Variable Immunodeficiency (CVID) is a heterogeneous group of disorders characterized by hypogammaglobulinemia and an increased susceptibility to recurrent infections as well as autoimmunity and malignancies. Idiopathic Thrombocytopenic Purpura (ITP) and Autoimmune Hemolytic Anemia (AIHA) are two autoimmune disorders which may be seen in association with CVID. Among 85 CVID patients, seve...

BACKGROUND The prevalence of primary immunodeficiency (PID) in the relatives of patients with common variable immunodeficiency (CVID) and IgA deficiency is high. Allergic disorders have been recorded in patients with humoral immunodeficiency. We aimed to determine the frequency of humoral immunodeficiency and atopy in the relatives of patients with CVID. METHODS The study population comprised...

BACKGROUND AND PURPOSE Common variable immunodeficiency (CVID) is a primary immunodeficiency disorder, which presents with hypogammaglobulinemia and recurrent bacterial infections. Patients with CVID have frequent and severe episodes of pneumonia. The standard intravenous immunoglobulins (IVIG) therapy has led to the reduction of pulmonary infections in these patients. The aim of this study was...

B-cell dysfunction. In summary, CVID is a heterogeneous immunodeficiency syndrome that spans a broad clinical spectrum. A small subset of patients with a presumptive diagnosis of CVID is spared recurrent infections despite hypogammaglobulinemia and impaired antibody responses to vaccines. Identification and registry of these patients will lead to broader awareness of CVID and will offer an oppo...

Common variable immunodeficiency (CVID), a frequent primary immunodeficiency disease, is characterized, by defects involving T and B cells. The Aiolos transcription factor plays an important role in the control of B cell differentiation and proliferation and is modulated through alternative splicing. In order to assess the role of Aiolos in this human pathology, we analyzed the Aiolos isoforms ...
