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...

Common Variable Immunodeficiency (CVID) is an antibody deficiency syndrome that often co-occurs in families with selective IgA deficiency (IgAD). This study was designed to investigate the frequency of DR and DQ loci of HLA class II region in common variable immunodeficiency (CVID) patients. Fifteen Iranian patients with CVID or IgAD (mean age 14.6±5.4, range 4-25 years; 9 male and 6 female) an...

BACKGROUND This study aimed at evaluating HRCT pulmonary manifestations in children with Common Variable Immunodeficiency (CVID) hospitalized in the Pediatric Ward of Masih Daneshvari Hospital during a 10-year period. MATERIALS AND METHODS This retrospective study evaluated 25 children hospitalized with the diagnosis of CVID in the Pediatric Ward of Masih Daneshvari Hospital from 2001 to 2011...

Chronic infection with norovirus is emerging as a significant risk for patients with immunodeficiency - either primary or secondary to therapeutic immunosuppression. Patients with primary immunodeficiency present a range of pathological responses to norovirus infection. Asymptomatic infections occur and differentiating viral carriage or prolonged viral shedding after self-limiting infection fro...

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 ...

BACKGROUND Common variable immunodeficiency (CVID) is an antibody deficiency with an equal sex distribution and a high variability in clinical presentation. The main features include respiratory tract infections and their associated complications, enteropathy, autoimmunity, and lymphoproliferative disorders. OBJECTIVE This study analyzes the clinical presentation, association between clinical...

Selective IgA deficiency (IgAD) and common variable immunodeficiency (CVID) are the most common primary immunodeficiencies in humans. A high degree of familial clustering, marked differences in the population prevalence among ethnic groups, association of IgAD and CVID in families, and a predominant inheritance pattern in multiple-case pedigrees have suggested a strong, shared genetic predispos...

Common variable immunodeficiency (CVID) has only scarcely been associated with ocular symptoms and rarely with retinal disease. In this case we describe a patient with distinct morphological and functional alterations in the retina. The patient presents with characteristic changes in retinal pigment epithelium, autofluorescence, and electrophysiology.

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...

Common variable immunodeficiency (CVID) presents in up to 25% of patients with autoimmune (AI) manifestations. Given the frequency and early onset in some patients with CVID, AI dysregulation seems to be an integral part of the immunodeficiency. Antibody-mediated AI cytopenias, most often affecting erythrocytes and platelets make up over 50% of these patients. This seems to be distinct from mai...
