    Low Serum IgE Is a Sensitive and Specific Marker for Common Variable Immunodeficiency (CVID).
    J Clin Immunol 2018 Feb 17. Epub 2018 Feb 17.
    Department of Medicine, University of Virginia, Box 801355, Charlottesville, VA, 22908, USA.
    Although small prior studies have suggested that IgE can be low in common variable immunodeficiency (CVID), the workup for patients with recurrent infections and suspected hypogammaglobulinemia does not include the routine measurement of serum IgE. We sought to test the hypothesis that low/undetectable serum IgE is characteristic of CVID by comparing the frequency of low/undetectable serum IgE in healthy controls and patients with CVID. We measured total serum IgE in a large multi-center cohort of patients with CVID (n = 354) and compared this to large population-based cohorts of children and adults. Read More

    Clinical Implications of Digenic Inheritance and Epistasis in Primary Immunodeficiency Disorders.
    Front Immunol 2017 26;8:1965. Epub 2018 Jan 26.
    School of Biological Sciences, University of Auckland, Auckland, New Zealand.
    The existence of epistasis in humans was first predicted by Bateson in 1909. Epistasis describes the non-linear, synergistic interaction of two or more genetic loci, which can substantially modify disease severity or result in entirely new phenotypes. The concept has remained controversial in human genetics because of the lack of well-characterized examples. Read More

    Proline-serine-threonine phosphatase interacting protein 1 (PSTPIP1) controls immune synapse stability in human T cells.
    J Allergy Clin Immunol 2018 Feb 9. Epub 2018 Feb 9.
    Department of Pediatric Immunology and Laboratory of Translational Immunology, Wilhelmina Children's Hospital, University Medical Center Utrecht, Utrecht, The Netherlands. Electronic address:
    Background: Proline-serine-threonine phosphatase interacting protein 1 (PSTPIP1) is a cytosolic adaptor protein involved with T-cell activation, differentiation, and migration. On cognate T-cell contact, PSTPIP1 is recruited to surface-expressed CD2, where it regulates F-actin remodeling. An immune synapse (IS) is thereby rapidly formed, consisting of T-cell receptor clusters surrounded by a ring of adhesion molecules, including CD2. Read More

    Human NF-κB1 Haploinsufficiency and Epstein-Barr Virus-Induced Disease-Molecular Mechanisms and Consequences.
    Front Immunol 2017 18;8:1978. Epub 2018 Jan 18.
    Ludwig Boltzmann Institute for Rare and Undiagnosed Diseases, Vienna, Austria.
    Nuclear factor kappa-light-chain-enhancer of activated B cells 1 (NF-κB1)-related human primary immune deficiencies have initially been characterized as defining a subgroup of common variable immunodeficiencies (CVIDs), representing intrinsic B-cell disorders with antibody deficiency and recurrent infections of various kind. Recent evidence indicates that NF-κB1 haploinsufficiency underlies a variable type of combined immunodeficiency (CID) affecting both B and T lymphocyte compartments, with a broadened spectrum of disease manifestations, including Epstein-Barr virus (EBV)-induced lymphoproliferative disease and immediate life-threatening consequences. As part of this review series focused on EBV-related primary immunodeficiencies, we discuss the current clinical and molecular understanding of monoallelic germline mutations with special focus on the emerging context of EBV-associated disease.

    J Immunol Res 2017 17;2017:7304658. Epub 2017 Dec 17.
    Department of Clinical Immunology and Allergy, Faculty of Medicine, Masaryk University, St. Anne's University Hospital, Brno, Czech Republic.
    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 diagnostic and prognostic potential. Serum immunoglobulin levels and levels of anti-Gal IgG, IgA, and IgM and anti-PCP IgG and IgG2 were determined in 59 CLL patients, 30 CVID patients, and 67 healthy controls. Read More

    An Activating Janus Kinase-3 Mutation Is Associated with Cytotoxic T Lymphocyte Antigen-4-Dependent Immune Dysregulation Syndrome.
    Front Immunol 2017 15;8:1824. Epub 2017 Dec 15.
    Center for Chronic Immunodeficiency, University Medical Center Freiburg, Freiburg, Germany.
    Heterozygous mutations in the cytotoxic T lymphocyte antigen-4 (CTLA-4) are associated with lymphadenopathy, autoimmunity, immune dysregulation, and hypogammaglobulinemia in about 70% of the carriers. So far, the incomplete penetrance of CTLA-4 haploinsufficiency has been attributed to unknown genetic modifiers, epigenetic changes, or environmental effects. We sought to identify potential genetic modifiers in a family with differential clinical penetrance of CTLA-4 haploinsufficiency. Read More

    Common Variable Immunodeficiency Non-Infectious Disease Endotypes Redefined Using Unbiased Network Clustering in Large Electronic Datasets.
    Front Immunol 2017 9;8:1740. Epub 2018 Jan 9.
    Massachusetts General Hospital, Boston, MA, United States.
    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 novel method to analyze inter-relationships between non-infectious disease outcomes in CVID using databases at the United States Immunodeficiency Network (USIDNET), the centralized immunodeficiency registry of the United States, and Partners, a tertiary care network in Boston, MA, USA, with a shared electronic medical record amenable to natural language processing.

    Autoimmune hepatitis as a complication of common variable immunodeficiency.
    Rev Esp Enferm Dig 2018 Mar;110(3):212-213
    Unidad de Gestión Clínica de Aparato Digestivo, Hospital Universitario Virgen del Rocío, España.
    In common variable immunodeficiency (CVID) there is a deregulation of the immune system, which frequently leads to an increased risk of infections, but also to autoimmunity phenomena. Autoimmune hepatitis may develop at any time of CVID's evolution, but it is difficult to diagnose due to the frequent absence of autoantibodies and low levels of IgG. Early diagnosis is important because targeted treatment may allow disease improvement. Read More

    High-Resolution Sequencing of Viral Populations during Early Simian Immunodeficiency Virus Infection Reveals Evolutionary Strategies for Rapid Escape from Emerging Env-Specific Antibody Responses.
    J Virol 2018 04 14;92(7). Epub 2018 Mar 14.
    Department of Biology, Boston College, Chestnut Hill, Massachusetts, USA
    Primate lentiviruses, including the human and simian immunodeficiency viruses (HIV and SIV), produce infections marked by persistent, ongoing viral replication. This occurs despite the presence of virus-specific adaptive immune responses, including antibodies targeting the viral envelope glycoprotein (Env), and evolution of antibody-escape variants is a well-documented feature of lentiviral infection. Here, we examined the evolutionary dynamics of the SIV gene during early infection (≤29 weeks postinfection) in a cohort of four SIV251-infected rhesus macaques. Read More

    A difficult diagnosis of coeliac disease: Repeat duodenal histology increases diagnostic yield in patients with concomitant causes of villous atrophy.
    Arab J Gastroenterol 2017 Dec 8;18(4):241-244. Epub 2018 Jan 8.
    Internal Medicine Section, DIBIMIS, University of Palermo, Italy.
    Villous atrophy in absence of coeliac disease (CD)-specific antibodies represents a diagnostic dilemma. We report a case of a woman with anaemia, weight loss and diarrhoea with an initial diagnosis of seronegative CD and a histological documented villous atrophy who did not improve on gluten-free diet due to the concomitant presence of common variable immunodeficiency (CVID) and Giardia lamblia infection. This case report confirms that CD diagnosis in CVID patients is difficult; the combination of anti-endomysial antibodies (EmA-IgA), anti-tissue transglutaminase antibodies (tTG-IgAb) antibodies and total IgA is obligatory in basic diagnostic of CD but in CVID are negative. Read More

    Common variable immunodeficiency (CVID) is characterised by repeated infection associated with primary acquired hypogammaglobulinemia. CVID frequently has a complex aetiology but, in certain cases, it has a monogenic cause. Recently, variants within the gene encoding the transcription factor STAT3 were implicated in monogenic CVID.

    Common variable immunodeficiency (CVID) is the most common form of primary immunodeficiency characterized by antibody deficiency, recurrent bacterial infections, and autoimmunity. Advanced chronic liver disease occurs in a subset of patients with CVID and manifests with various histological features, such as nodular regenerative hyperplasia, inflammation, fibrosis, and cholangiopathy. We present a case series characterizing the outcomes in adult patients transplanted for primary CVID-related liver disease. Read More
