In the article, “Inversion of the Vd1 to Vd2 gd T cell ratio in CVID is not restored by IVIg and is associated with immune activation and exhaustion”, which appeared in Volume 95, Issue 30, the age ranges for CVID patients and for the healthy controls appeared incorrectly in the Study Cohort and Samples section. “Fifteen CVID patients (10 females and 5 males aged 6–51, average 34) from the Prim...

Common variable immunodeficiency (CVID) is a heterogeneous primary immunodeficiency disease, leading to recurrent bacterial airway infections and often also autoimmune complications. To shed light on the regulatory lymphocytes from these patients, we analyzed the levels of regulatory B (pro-B10) cell and regulatory T (Treg) cell subpopulations in PBMCs from twenty-six patients diagnosed with CV...

Common variable immunodeficiency (CVID) is a heterogenous disorder characterized by hypogammaglobulinemia and impaired specific antibody response and increased susceptibility to infections, autoimmunity and malignancies. A number of gene mutations, including ICOS, TACI and BAFF-R, and CD19, CD20, CD21, CD81, MSH5 and LRBA have been described; however, they account for approximately 20-25% of to...

BACKGROUND Common variable immunodeficiency (CVID) is the most common symptomatic antibody deficiency. It is characterized by hypogammaglobulinemia, increased susceptibility to recurrent infections, autoimmunity, and malignancies. OBJECTIVES To determine whether patients with CVID have cytokine production defects after T-cell activation and to assess whether or not these are correlated with m...

BACKGROUND Common variable immune deficiency (CVID) is a heterogeneous syndrome with a wide variety of signs and symptoms. This study describes the phenotyping and survival of the CVID patients in the allergy and clinical immunology department of Rasol-E-Akram Hospital of Iran University of Medical Sciences in Tehran. METHOD We retrospectively reviewed hospital files of CVID patients in our d...

Abstract Adiponectin and leptin are adipokines, secreted by white adipose tissue (WAT), which play an important role in energy homeostasis. Some evidence has shown that adipokine‐producing cells present the bone marrow (BM) appear to exert influence on hematopoiesis B cell development. Common variable immunodeficiency (CVID) is one of most common inborn errors immunity humans. In CVID, numerica...

Adiponectin (Acrp30) is an adipokine widely studied for its beneficial metabolic properties. It circulates as low molecular weight (LMW), medium molecular weight (MMW), and high molecular weight (HMW) oligomers. The latter exerts the most potent biological effects. Acrp30 attracted renewed interest with the finding that it was associated with the development and progression of immune disorders....

BACKGROUND Common variable immunodeficiency (CVID) is the term used to describe a heterogeneous group of B-cell deficiency syndromes characterized by hypogammaglobulinemia, impaired antibody production, and recurrent bacterial infections. OBJECTIVES To determine the clinical manifestations and perform an immunological analysis of pediatric CVID patients suffering from respiratory complication...

Common variable immunodeficiency (CVID) is the most frequent clinically manifested primary immunodeficiency. According to clinical and laboratory findings, CVID is a heterogeneous group of diseases. Recently, the defects of molecules regulating activation and terminal differentiation of B lymphocytes have been described in some patients with CVID. In this study, we show the overview of deficien...

BACKGROUND Common variable immunodeficiency (CVID) is a primary immune deficiency defined by defective antibody production. In most series, a small proportion of patients present with opportunistic infections (OIs). METHODS The French DEFI study has enrolled patients with primary hypogammaglobulinemia and allows a detailed clinical and immunologic description of patients with previous OIs and...
