Proc Natl Acad Sci U S A 2018 11 12;115(48):E11369-E11378. Epub 2018 Nov 12.

Hepatic Pathogenesis Section, Laboratory of Infectious Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda, MD 20892;

Hepatitis B virus (HBV)-associated acute liver failure (ALF) is a dramatic clinical syndrome leading to death or liver transplantation in 80% of cases. Due to the extremely rapid clinical course, the difficulties in obtaining liver specimens, and the lack of an animal model, the pathogenesis of ALF remains largely unknown. Here, we performed a comprehensive genetic and functional characterization of the virus and the host in liver tissue from HBV-associated ALF and compared the results with those of classic acute hepatitis B in chimpanzees.

CD3/CD19 Depleted Matched and Mismatched Unrelated Donor Hematopoietic Stem Cell Transplant with Targeted T Cell Addback Is Associated with Excellent Outcomes in Pediatric Patients with Nonmalignant Hematologic Disorders.

Biol Blood Marrow Transplant 2018 Oct 9. Epub 2018 Oct 9.

Cellular Therapy and Transplant Section, Division of Oncology Children's Hospital of Philadelphia, Philadelphia, Pennsylvania; Department of Pediatrics, Perelman School of Medicine of the University of Pennsylvania, Philadelphia, Pennsylvania. Electronic address:

Unrelated donor hematopoietic stem cell transplantation (HSCT) is increasingly being used to cure nonmalignant hematologic diseases (NMHD) in patients who lack HLA matched related donors. Both graft rejection and graft-versus-host disease (GVHD) remain major barriers to safe and effective transplant for these patients requiring unrelated donors. Partial T cell depletion combined with peripheral stem cell transplantation (pTCD-PSCT) has the potential advantages of providing a high stem cell dose to facilitate rapid engraftment, maintaining cells that may facilitate engraftment, and decreasing GVHD risk compared with T cell-replete HSCT.

The Case for Cardiac Xenotransplantation in Neonates: Is Now the Time to Reconsider Xenotransplantation for Hypoplastic Left Heart Syndrome?

Pediatr Cardiol 2018 Oct 9. Epub 2018 Oct 9.

Xenotransplantation Program, Department of Surgery, University of Alabama at Birmingham, Birmingham, AL, USA.

Neonatal cardiac transplantation for hypoplastic left heart syndrome (HLHS) is associated with excellent long-term survival compared to older recipients. However, heart transplantation for neonates is greatly limited by the critical shortage of donor hearts, and by the associated mortality of the long pre-transplant waiting period. This led to the development of staged surgical palliation as the first-line surgical therapy for HLHS. Read More

Venetoclax in Combination with Decitabine for Relapsed T-Cell Acute Lymphoblastic Leukemia after Allogeneic Hematopoietic Cell Transplant.

Case Rep Hematol 2018 26;2018:6092646. Epub 2018 Aug 26.

Department of Hematologic Malignancies and Blood and Marrow Transplant, University of California, San Francisco, CA, USA.

Long-term disease-free survival in adults with T-cell acute lymphoblastic leukemia (T-ALL) remains poor, particularly after relapse, with few available salvage options. Preclinical data suggest that inhibition of the antiapoptotic protein BCL-2 (B-cell lymphoma 2) either alone or in combination with other agents, may be a unique therapeutic approach for the treatment of T-ALL. We present a case of a young male with T-ALL, relapsed after allogeneic hematopoietic stem cell transplant, who achieved a second complete remission following salvage therapy with combined venetoclax and decitabine.

Hypomorphic caspase activation and recruitment domain 11 (CARD11) mutations associated with diverse immunologic phenotypes with or without atopic disease.

J Allergy Clin Immunol 2018 Aug 28. Epub 2018 Aug 28.

Department of Pharmacology & Molecular Therapeutics, Uniformed Services University of the Health Sciences, Bethesda, Md. Electronic address:

Background: Caspase activation and recruitment domain 11 (CARD11) encodes a scaffold protein in lymphocytes that links antigen receptor engagement with downstream signaling to nuclear factor κB, c-Jun N-terminal kinase, and mechanistic target of rapamycin complex 1. Germline CARD11 mutations cause several distinct primary immune disorders in human subjects, including severe combined immune deficiency (biallelic null mutations), B-cell expansion with nuclear factor κB and T-cell anergy (heterozygous, gain-of-function mutations), and severe atopic disease (loss-of-function, heterozygous, dominant interfering mutations), which has focused attention on CARD11 mutations discovered by using whole-exome sequencing.

Objectives: We sought to determine the molecular actions of an extended allelic series of CARD11 and to characterize the expanding range of clinical phenotypes associated with heterozygous CARD11 loss-of-function alleles. Read More

Modern specific features and therapy of psoriasis and arthropathic psoriasis courses.

Wiad Lek 2018 ;71(2 pt 1):322-325

Danylo Halytsky Lviv National Medical University, Lviv, Ukraine.

Objective: Introduction:Psoriasis affects about 2% of population. In 30-40% of occurrences arthropathic psoriasis (AP) is diagnosed and it leads to 11-19% of disability cases development. Recent studies have shown that psoriasis is often synergistically combined with herpesvirus of the 1st and 2nd type, which, according to many scientists, determines the severity, frequency of recurrences, and the course of this dermatosis.

B-cell differentiation and IL-21 response in SCID patients after hematopoietic stem cell transplantation.

Blood 2018 Jun 4;131(26):2967-2977. Epub 2018 May 4.

Division of Pediatric Hematology-Oncology, Boston Children's Hospital, Boston, MA.

Allogeneic hematopoietic stem cell transplant (HSCT) typically results in donor T-cell engraftment and function in patients with severe combined immunodeficiency (SCID), but humoral immunity, particularly when using donors other than matched siblings, is variable. B-cell function after HSCT for SCID depends on the genetic cause, the use of pre-HSCT conditioning, and whether donor B-cell chimerism is achieved. Patients with defects in or undergoing HSCT without conditioning often have poor B-cell function post-HSCT, perhaps as a result of impairment of IL-21 signaling in host-derived B cells. Read More

Immunogenicity and Immunological Memory Induced by the 13-Valent Pneumococcal Conjugate Followed by the 23-Valent Polysaccharide Vaccine in HIV-Infected Adults.

J Infect Dis 2018 Jun;218(1):26-34

Immunobiology and Vaccinology Research Laboratory, Aghia Sophia Children's Hospital.

Background: Vaccine-induced memory B-cell (MBC) subsets have distinct roles in the establishment of protective immunity; MBCs expressing nonswitched immunoglobulin M (IgM+ MBCs) replenish the MBC pool, whereas MBCs expressing isotype-switched immunoglobulin (sIg+ MBCs) differentiate into plasma cells upon antigen reencounter. We investigated immunogenicity and MBCs induced by combined 13-valent pneumococcal conjugate vaccine (PCV13) and 23-valent pneumococcal polysaccharide vaccine (PPV23) in human immunodeficiency virus (HIV)-infected adults.

Methods: Forty HIV-seropositive adults receiving ART with undetectable viral loads were enrolled. Read More

Multispectral fluorescence-activated cell sorting of B and T cell subpopulations from equine peripheral blood.

Vet Immunol Immunopathol 2018 May 23;199:22-31. Epub 2018 Mar 23.

Baker Institute for Animal Health, College of Veterinary Medicine, Cornell University, Ithaca, NY, 14850, USA.

Immune phenotyping of equine peripheral blood mononuclear cells (PBMC) is commonly described by single or double marker labeling, which limits complex phenotypic descriptions and subpopulation identification. Our objective was to develop a new multispectral flow cytometry protocol to identify and sort equine lymphocyte subpopulations using commercially available, pre-conjugated monoclonal antibodies to cell surface markers. Two clones of anti-equine CD8 (CVS8 and CVS21) were compared in combination with CD3. Read More

Heterologous Prime-Boost Combinations Highlight the Crucial Role of Adjuvant in Priming the Immune System.

Front Immunol 2018 12;9:380. Epub 2018 Mar 12.

Laboratory of Molecular Microbiology and Biotechnology, Department of Medical Biotechnologies, University of Siena, Siena, Italy.

The induction and modulation of the immune response to vaccination can be rationally designed by combining different vaccine formulations for priming and boosting. Here, we investigated the impact of heterologous prime-boost approaches on the vaccine-specific cellular and humoral responses specific for a mycobacterial vaccine antigen. C57BL/6 mice were primed with the chimeric vaccine antigen H56 administered alone or with the CAF01 adjuvant, and boosted with H56 alone, or combined with CAF01 or with the squalene-based oil-in-water emulsion adjuvant (o/w squalene).

Hypophysitis following Treatment with Ustekinumab: Radiological and Pathological Findings.

Front Endocrinol (Lausanne) 2018 9;9:83. Epub 2018 Mar 9.

Department of Endocrinology, Hospital Universitario de la Princesa, Instituto de Investigación Princesa, Universidad Autónoma de Madrid, Madrid, Spain.

Context: Ustekinumab is a human IgG1 monoclonal antibody that targets interleukin (IL)-12 and IL-23, which may be useful in the treatment of autoimmune conditions such as psoriasis, psoriatic arthritis, and Crohn's disease. Hypophysitis is an immune-derived inflammatory condition of the pituitary gland that may lead to pituitary dysfunction. With the increasing use of immunotherapy, it is possible that this and other new immune-related adverse events (IRAEs) arise, although the mechanisms involved are still incompletely defined.

Lenalidomide as immune adjuvant to a dendritic cell vaccine in chronic lymphocytic leukemia patients.

Eur J Haematol 2018 Jul 22;101(1):68-77. Epub 2018 May 22.

Department of Oncology-Pathology, Karolinska Institutet, Stockholm, Sweden.

Objectives: We previously showed that immunization with ex vivo- generated autologous dendritic cells loaded with apoptotic tumor cells (Apo-DC) potentiated tumor-specific immunity in chronic lymphocytic leukemia (CLL) patients. Here, we evaluated safety and immunogenicity of Apo-DC in combination with lenalidomide, granulocyte-macrophage colony-stimulating factor (GM-CSF), and low-dose cyclophosphamide (CTX).

Methods: Ten previously untreated patients with slowly progressing CLL received 5 Apo-DC vaccinations and lenalidomide orally for 24 weeks either alone (cohort I, n = 5) or together with subcutaneous GM-CSF and intravenous CTX (cohort II, n = 5). Read More

Respiratory Manifestations of the Activated Phosphoinositide 3-Kinase Delta Syndrome.

Front Immunol 2018 5;9:338. Epub 2018 Mar 5.

Department of Medicine, University of Cambridge, Cambridge, United Kingdom.

The activated phosphoinositide 3-kinase δ syndrome (APDS), also known as p110δ-activating mutation causing senescent T cells, lymphadenopathy, and immunodeficiency (PASLI), is a combined immunodeficiency syndrome caused by gain-of-function mutations in the phosphoinositide 3-kinase (PI3K) genes (encoding p110δ: APDS1 or PASLI-CD) and (encoding p85α: APDS2 or PASLI-R1). While the disease is clinically heterogeneous, respiratory symptoms and complications are near universal and often severe. Infections of the ears, sinuses, and upper and lower respiratory tracts are the earliest and most frequent manifestation of APDS, secondary to both respiratory viruses and to bacterial pathogens typical of defective B cell function.

Good's Syndrome-Association of the Late Onset Combined Immunodeficiency with Thymoma: Review of Literature and Case Report.

Iran J Allergy Asthma Immunol 2018 Feb;17(1):85-93

Pediatric Respiratory Diseases Research Center, National Research Institute of Tuberculosis and Lung Diseases (NRITLD), Shahid Beheshti University of Medical Sciences, Tehran, Iran.

Good's syndrome, the adult onset hypogammaglobulinemia associated with thymoma has been explained about six decades ago. It generally presents with recurrent infections and several paraneoplastic syndromes including myasthenia gravis, pure red cell aplasia, connective tissue disorders, superior vena cava, Horner's syndrome, lichen planus and inflammatory bowel disease. Lack of B cell, dysfunction of T cell, CD4+ T cell lymphopenia, reversed CD4/CD8+ T cell ratio, autoantibodies against Th17 related cytokines have been respected as the pathogenesis of the immune dysregulation this syndrome.

Novel CARMIL2 Mutations in Patients with Variable Clinical Dermatitis, Infections, and Combined Immunodeficiency.

Front Immunol 2018 9;9:203. Epub 2018 Feb 9.

Department of Genetics, King Faisal Specialist Hospital and Research Centre, Riyadh, Saudi Arabia.

Combined immunodeficiencies are a heterogeneous collection of primary immune disorders that exhibit defects in T cell development or function, along with impaired B cell activity even in light of normal B cell maturation. CARMIL2 (RLTPR) is a protein involved in cytoskeletal organization and cell migration, which also plays a role in CD28 co-signaling of T cells. Mutations in this protein have recently been reported to cause a novel primary immunodeficiency disorder with variable phenotypic presentations. Read More
