Common variable immunodeficiency (CVID) is a common primary immunodeficiency characterized by a failure in B-cell differentiation with defective immunoglobulin production. Affected patients are uniquely susceptible to recurrent infection with encapsulated organisms and have an increased propensity for the development of inflammatory and autoimmune manifestations. The diagnosis of CVID is common...

Common variable immunodeficiency (CVID) is the most common form of severe antibody deficiency. The disorder is associated with a broad spectrum of clinical manifestations, including infections and chronic lung, gastrointestinal and autoimmune diseases. A 29-year-old female patient has had frequent sinopulmonary infections and gastroenteritis for the last 20 years and had been given broad-spectr...

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...

BACKGROUND Antagonists of N-type voltage-gated calcium channels (VGCC), Ca(v)2.2, can manage severe chronic pain with intrathecal use and may be effective systemically. A series of novel ω-conotoxins that selectively inhibit N-type VGCCs was isolated from Conus catus. In the present study, the potency and reversibility of ω-conotoxins CVID, CVIE and CVIF to inhibit N-type calcium currents were ...

Humoral deficiencies represent a broad group of disorders. The aim of the study was to compare the levels of antibodies against pneumococcal capsular polysaccharides (anti-PCP) and natural anti-galactosyl (anti-Gal) antibodies in (1) patients with chronic lymphocytic leukaemia (CLL), (2) patients with common variable immunodeficiency (CVID), and (3) a healthy population and to explore their dia...

In some patients with common variable immunodeficiency (CVID) and immunoglobulin (Ig) A deficiency (IgAD), tumor necrosis factor (TNF) family receptor transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI) gene mutations have been reported. B cells from individuals with TACI mutations do not produce IgG and IgA in response to the TACI ligand a proliferation-induc...

objective: common variable immunodeficiency (cvid) is one of the most frequent cases of primary immunodeficiency. it is likely that this heterogeneous disease is caused by several distinct genetic disorders. the activation-induced cytidine deaminase (aid) enzyme is involved in class switching, somatic hypermutation (shm) and processes associated with gene conversion in the germinal center. in o...

BACKGROUND/AIMS Common variable immunodeficiency (CVID) is an immunological disorder characterised by defective antibody production. Patients with CVID have a high risk of gastric cancer. It has been suggested that gastric cancer results from an interaction between environmental factors and a genetic predisposition. The role of Helicobacter pylori as an environmental factor in gastric carcinoge...

(CVID) is the most frequent primary immunodeficiency, characterized by reduced levels of immunoglobulins [1,2]. Due to a heterogeneous presentation including a heightened rate of infections, the diagnosis is often delayed for 4–9 years. This delay may contribute to the increased morbidityandmortality in CVIDpatients [1,3]. Gastrointestinal manifestations – most often chronic diarrhea [2] – are ...

Hypogammaglobulinemia (serum IgG lower than 2 SD below the age-matched mean) and clinical symptoms such as increased susceptibility to infection, autoimmune manifestations, granulomatous disease, and unexplained polyclonal lymphoproliferation are considered to be diagnostic hallmarks in patients with common variable immunodeficiency (CVID), the most frequent clinically severe primary immunodefi...
