    Heterogeneity of GATA2-related myeloid neoplasms.
    Int J Hematol 2017 Jun 22. Epub 2017 Jun 22.
    Department of Pediatrics and Adolescent Medicine, Division of Pediatric Hematology and Oncology, Medical Center, Faculty of Medicine, University of Freiburg, Freiburg, Germany.
    The GATA2 gene codes for a master hematopoietic transcription factor that is essential for the proliferation and maintenance of hematopoietic stem and progenitor cells. Heterozygous germline mutations in GATA2 have been initially associated with several clinical entities that are now collectively defined as GATA2 deficiency. Despite pleiotropic clinical manifestations, the high propensity for the development of myelodysplastic syndromes (MDS) constitutes the most common clinical denominator of this major MDS predisposition syndrome.

    A Review on Defects of Dendritic Cells in Common Variable Immunodeficiency.
    Endocr Metab Immune Disord Drug Targets 2017 Jun 13. Epub 2017 Jun 13.
    Department of Laboratory Medicine, Imam Hassan Mojtaba Hospital, Alborz University of Medical Sciences, Karaj. Iran.
    Background And Objectives: Common variable immunodeficiency (CVID) is the most important primary that is associated with clinical complications including recurrent infections, malignancy and autoimmune diseases. The genetic cause of CVID is mostly unknown and only a few genetic causes are identified. The various options are proposed for determining the etiology of CVID patients, such as T- and B-cell defects, Toll-like receptors (TLRs) impairments, altered cytokine production as well as blemished dendritic cells (DCs).

    Early-onset primary antibody deficiency resembling common variable immunodeficiency challenges the diagnosis of Wiedeman-Steiner and Roifman syndromes.
    Sci Rep 2017 Jun 16;7(1):3702. Epub 2017 Jun 16.
    Clinical Immunology Research Lab, Department of Pulmonary Medicine, Centre for Primary Immunodeficiency, Jeffrey Modell Diagnosis and Research Centre, Ghent University Hospital, Ghent, Belgium.
    Syndromic primary immunodeficiencies are rare genetic disorders that affect both the immune system and other organ systems. More often, the immune defect is not the major clinical problem and is sometimes only recognized after a diagnosis has been made based on extra-immunological abnormalities. Here, we report two sibling pairs with syndromic primary immunodeficiencies that exceptionally presented with a phenotype resembling early-onset common variable immunodeficiency, while extra-immunological characteristics were not apparent at that time.

    Murine LRBA-deficiency causes CTLA-4 deficiency in Tregs without progression to immune dysregulation.
    Immunol Cell Biol 2017 Jun 14. Epub 2017 Jun 14.
    Immunology Division, Garvan Institute for Medical Research, Sydney, Australia.
    Inherited mutations in Lipopolysaccharide Responsive Beige-like Anchor (LRBA) cause a recessive human immune dysregulation syndrome with memory B cell and antibody deficiency (common variable immunodeficiency, CVID), inflammatory bowel disease, enlarged spleen and lymph nodes, accumulation of activated T cells, and multiple autoimmune diseases. To understand the pathogenesis of the syndrome, C57BL/6 mice carrying a homozygous truncating mutation in Lrba were produced using CRISPR/Cas9-mediated gene targeting. These mice revealed that LRBA plays a critical, cell autonomous role in promoting CTLA-4 accumulation within CD4 effector T cells and FOXP3(+) T regulatory cells (Tregs). Read More

    Comparison of Bone Mineral Density in Common variable immunodeficiency and X-Linked Agammaglobulinaemia Patients.
    Endocr Metab Immune Disord Drug Targets 2017 Jun 11. Epub 2017 Jun 11.
    Pediatric Research Center, Qom University of Medical Sciences, Qom. Iran.
    Background: Primary antibody deficiency (PAD) is the most common group of primary immunodeficiency disorders, resulting from different defects in development and function of B cell lineage. Common variable immunodeficiency (CVID) and X-linked agammaglobulinemia (XLA) are two of the major types of PADs. Optimal growth and subsequently bone health could potentially compromise due to the interference of several factors in PAD with childhood onset. Read More

    Immune deficiency and autoimmunity in patients with CTLA-4 mutations.
    Clin Exp Immunol 2017 Jun 10. Epub 2017 Jun 10.
    Institute of Immunity and Transplantation, Division of Infection & Immunity, School of Life and Medical Sciences, University College London, Royal Free Hospital, Rowland Hill Street, London, NW3 2PF, UK.
    Immune deficiency disorders are a heterogeneous group of diseases of variable genetic aetiology. Whilst the hallmark of immunodeficiency is susceptibility to infection, it is increasingly clear that autoimmunity is prevalent suggestive of a more general immune dysregulation in some cases. With the increasing use of genetic technologies the underlying causes of immune dysregulation are beginning to emerge. Read More

    A case report of lymphoid intestitial pneumonia in common variable immunodeficiency: Oligoclonal expansion of effector lymphocytes with preferential cytomegalovirus-specific immune response and lymphoproliferative disease promotion.
    Medicine (Baltimore) 2017 Jun;96(23):e7031
    aDepartment of Clinical Immunology, Lower Silesian Center for Cellular Transplantation bL Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences, Wroclaw cDepartment of Immunology, Poznan University of Medical Sciences, Poznań, Poland.
    Rationale: Lymphoid interstitial pneumonia (LIP) is a rare disease with lymphocytic infiltration of the alveolar interstitial and air spaces, sometimes classified as a clonal lymphoproliferative disease (LPD) with high prevalence in patients with immunodysregulation. Although association of mucosa-associated lymphoid tissue (MALT) lymphoma development with infectious agents has been well described, it is not so in the case of LIP. Attempts to demonstrate an infective cause by direct microbe detection have failed, but association with atypical specific immune response to opportunistic infectious agent has not been studied.

    Granulomatous-Lymphocytic Interstitial Lung Disease in a Patient With Common Variable Immunodeficiency.
    Curr Probl Diagn Radiol 2017 Apr 14. Epub 2017 Apr 14.
    Department of Radiology, University of Florida, Gainesville, FL.
    Common variable immunodeficiency is the most common primary immunodeficiency and consists of impaired immunoglobulin production causing recurrent sinopulmonary infections. The most common cause of mortality for this disorder, however, is from the development of malignancy and autoimmune disorders. One common entity that develops is a systemic granulomatous and lymphoproliferative disorder that can cause an interstitial lung disease more formally referred to as granulomatous-lymphocytic interstitial lung disease (GL-ILD).

    A Case Report of Hypoglycemia and Hypogammaglobulinemia: DAVID syndrome in a patient with a novel NFKB2 mutation.
    J Clin Endocrinol Metab 2017 May 3. Epub 2017 May 3.
    Division of Allergy, Immunology & Rheumatology, Departments of Pediatrics, Stanford University School of Medicine, Stanford, California.
    Context: DAVID syndrome (Deficient Anterior pituitary with Variable Immune Deficiency) is a rare disorder in which children present with symptomatic ACTH deficiency preceded by hypogammaglobulinemia from B-cell dysfunction with recurrent infections, termed common variable immunodeficiency (CVID). Subsequent whole exome sequencing studies have revealed germline heterozygous C-terminal mutations of NFKB2 as either a cause of DAVID syndrome or of CVID without clinical hypopituitarism. However, to the best of our knowledge there have been no cases in which the endocrinopathy has presented in the absence of a prior clinical history of CVID. Read More

    Immune dysregulation in immunodeficiency disorders: The role of T-cell receptor sequencing.
    J Autoimmun 2017 Jun 8;80:1-9. Epub 2017 Apr 8.
    Massachusetts General Hospital Cancer Center and Department of Medicine Harvard Medical School, 13th Street, Charlestown, MA, 02129, USA. Electronic address:
    Immune dysregulation is a prominent feature of primary immunodeficiency disorders, which commonly manifested as autoimmunity, cytopenias and inflammatory bowel disease. In partial T-cell immunodeficiency disorders, it has been proposed that the imbalance between effector and regulatory T-cells drives the breakdown of peripheral tolerance. While there is no robust test for immune dysregulation, the T-cell receptor repertoire is used as a surrogate marker, and has been shown to be perturbed in a number of immunodeficiency disorders featuring immune dysregulation including Omenn's Syndrome, Wiskott-Aldrich Syndrome, and common variable immunodeficiency.

    Type III Hypersensitivity Reaction to Subcutaneous Insulin Preparations in a Type 1 Diabetic.
    J Gen Intern Med 2017 Jul 23;32(7):841-845. Epub 2017 Mar 23.
    Duke University School of Medicine, 3643 N Roxboro Rd, Durham, NC, 27704, USA.
    Management of type 1 diabetes in patients who have insulin hypersensitivity is a clinical challenge and places patients at risk for recurrent diabetic ketoacidosis (DKA). Hypersensitivity reactions can be due to the patient's response to the insulin molecule itself or one of the injection's non-insulin components. It is therefore crucial for clinicians to quickly recognize the type of hypersensitivity reaction that is occurring and identify potentially immunogenic additives for the purpose of directing therapy as various insulin preparations have differing ingredients.

    Plasmablast Response to Primary Rhesus Cytomegalovirus (CMV) Infection in a Monkey Model of Congenital CMV Transmission.
    Clin Vaccine Immunol 2017 May 5;24(5). Epub 2017 May 5.
    Duke Human Vaccine Institute, Duke University Medical Center, Durham, North Carolina, USA
    Human cytomegalovirus (HCMV) is the most common congenital infection worldwide and the leading infectious cause of neurologic deficits and hearing loss in newborns. Development of a maternal HCMV vaccine to prevent vertical virus transmission is a high priority, yet protective maternal immune responses following acute infection are poorly understood. To characterize the maternal humoral immune response to primary CMV infection, we investigated the plasmablast and early antibody repertoire using a nonhuman primate model with two acutely rhesus CMV (RhCMV)-infected animals-a CD4(+) T cell-depleted dam that experienced fetal loss shortly after vertical RhCMV transmission and an immunocompetent dam that did not transmit RhCMV to her infant.

    Considerations for dosing immunoglobulin in obese patients.
    Clin Exp Immunol 2017 Jun 17;188(3):353-362. Epub 2017 Apr 17.
    Corporate Medical Affairs, Biotest AG, Dreieich, Germany.
    Obesity is a very common condition; however, the effect of excess body weight on the appropriate dose of immunoglobulin has not been defined empirically. The proposed pharmacokinetic differences between lean and obese patients and the opportunity to reduce costs has led to the proposition that obese patients should receive proportionally lower doses of immunoglobulin once a certain threshold is reached. Here the theoretical factors which could affect dosing in obese patients are considered alongside the available empirical evidence. Read More
