BACKGROUND: Vitamin D is an important hormone that regulates cardiac myocyte function. Low levels contribute to the development of cardiovascular disease and have been implicated in immune function and the inflammatory cascade. Patients who undergo left ventricular assist device (LVAD) implantation are at risk for driveline infection, stroke, and gastrointestinal (GI) bleeding. We investigated whether serum 25-hydroxy (25-OH) vitamin D levels affect clinical outcomes after LVAD. METHODS: 212 patients who underwent LVAD implantation between 2010 and 2015 were included...

BACKGROUND: Influenza causes significant morbidity and mortality; the pandemic in 2009-2010 was a reminder of the potential for novel strains and antigenic changes. Studies have shown that vitamin D deficiency may be associated with poor vaccine immunogenicity, therefore we sought to determine if there was a correlation between 25-hydroxyvitamin D [25(OH)D] and influenza vaccine response. METHODS: A retrospective observational study was conducted among young, healthy military members to evaluate the association between total 25(OH)D levels with post influenza vaccination antibody titers and healthcare encounters during the 2009-10 influenza season...

Acquired immune deficiency syndrome (AIDS) is a spectrum of conditions caused by infection with the human immunodeficiency virus (HIV). Two types of HIV have been characterized: HIV-1 and HIV-2. The present study investigated whether evolutionary selection pressure differs between rapid progressor (RP), slow progressor (SP), and long-term non-progressor (LTNP) of HIV-I infected individuals. An unexpected association between the evolutionary rate of substitution in envelope (env) gene and disease progression is observed...

BACKGROUND: Despite three decades of scientific response to HIV/AIDS, the generalised HIV epidemic continues to persist in South Africa. There is growing acknowledgement that health system strengthening will be critical in tackling HIV/AIDS. Patient rehospitalisation is an important quality benchmark of health service delivery, but there is currently limited data on rehospitalisation of patients with HIV/AIDS in South Africa, a setting with a high burden of HIV disease. OBJECTIVES: To determine the relationship between combined HIV serostatus and CD4 count, and rehospitalisation in South Africa...

MHC class I downregulation represents a significant challenge for successful T cell-based immunotherapy. T cell epitopes associated with impaired peptide processing (TEIPP) constitute a novel category of immunogenic Ags that are selectively presented on transporter associated with Ag processing-deficient cells. The TEIPP neoepitopes are CD8 T cell targets, derived from nonmutated self-proteins that might be exploited to prevent immune escape. In this study, the crystal structure of H-2D(b) in complex with the first identified TEIPP Ag (MCLRMTAVM) derived from the Trh4 protein has been determined to 2...

Three members of the caspase recruitment domain (CARD) family of adaptors (CARD9, CARD10, and CARD11) are known to form heterotrimers with B-cell lymphoma 10 (BCL10) and mucosa-associated lymphoid tissue lymphoma-translocation gene 1 (MALT1). These 3 CARD-BCL10-MALT1 (CBM) complexes activate nuclear factor κB in both the innate and adaptive arms of immunity. Human inherited defects of the 3 components of the CBM complex, including the 2 adaptors CARD9 and CARD11 and the 2 core components BCL10 and MALT1, have recently been reported...

BACKGROUND: Although routine human immune deficiency virus (HIV) testing during health care visits is recommended for most adults, many older adults (i.e., ages 50-64 years) do not receive it. This study identified factors associated with HIV testing in the past 12 months (i.e., recent HIV testing) among US adults in the 3 categories of older adulthood (50-54, 55-59, and 60-64 years) for which routine HIV testing is recommended. METHOD: This was a cross-sectional analysis of data from US older adult respondents to the 2010 Behavioral Risk Factor Surveillance System...

Significant research has been conducted to better understand the extensive, heterogeneous molecular features of triple-negative breast cancer (TNBC). We reviewed published TNBC molecular classifications to identify major groupings that have potential for clinical trial development. With the ultimate aim to streamline translational medicine, we linked these categories of TNBC according to their gene-expression signatures, biological function, and clinical outcome. To this end, we define five potential clinically actionable groupings of TNBC: 1) basal-like TNBC with DNA-repair deficiency or growth factor pathways; 2) mesenchymal-like TNBC with epithelial-to-mesenchymal transition and cancer stem cell features; 3) immune-associated TNBC; 4) luminal/apocrine TNBC with androgen-receptor overexpression; and 5) HER2-enriched TNBC...

In 1993, it is estimated that 2 million Americans are infected with the human Immunodeficiency Virus (HIV). The Acquired Immune Deficiency Syndrome (AIDS) represents the most severe manifestation of infection with the virus. In the patient with AIDS, helper T lymphocytes are depleted resulting in a defect in cell mediated immunity. The resulting state of profound immunosuppression leads to susceptibility to rare infections and tumors. Although opportunistic infections have been seen in patients on immunosuppressive therapy, those associated with AIDS are much more severe and extensive...

BACKGROUND: Anemia is common in tuberculosis, and multiple etiologies necessitate targeted interventions. The proportion of iron-responsive anemia due to iron deficiency compared with iron-unresponsive anemia due to impaired iron absorption/redistribution from tuberculosis-associated immune activation or inflammation is unknown. This impedes selection of safe and effective treatment and appropriate intervention timing. METHODS: Baseline hemoglobin, ferritin, hepcidin, soluble transferrin receptor (sTfR), and transferrin were measured in 45 patients with confirmed pulmonary tuberculosis (cases), 47 tuberculin skin test (TST)-positive controls, and 39 TST-negative controls in The Gambia...

The generation of naïve T lymphocytes is critical for immune function yet the mechanisms governing their maturation remain incompletely understood. We have identified a mouse mutant, bloto, that harbors a hypomorphic mutation in the zinc finger protein Zfp335. Zfp335(bloto/bloto) mice exhibit a naïve T cell deficiency due to an intrinsic developmental defect that begins to manifest in the thymus and continues into the periphery, affecting T cells that have recently undergone thymic egress. The effects of Zfp335(bloto) are multigenic and cannot be attributed to altered thymic selection, proliferation or Bcl2-dependent survival...

Poor micronutrient levels are associated with an increased risk of progression to AIDS and are also suggested to influence outcome of highly active antiretroviral therapy (HAART), though existing data are inconclusive to support the latter. Few published data are available on micronutrient levels in Ethiopian HIV/AIDS patients taking HAART. The objective of the study was to determine the association of micronutrient levels and response to HAART (CD4(+) T cell count) among adult HIV/AIDS patients attending a teaching Hospital in Addis Ababa...

OBJECTIVE: Macrophage activation syndrome (MAS), a life-threatening complication of systemic juvenile idiopathic arthritis (JIA), resembles familial hemophagocytic lymphohistiocytosis (HLH), a constellation of autosomal-recessive immune disorders resulting from deficiency in cytolytic pathway proteins. We undertook this study to test our hypothesis that MAS predisposition in systemic JIA could be attributed to rare gene sequence variants affecting the cytotolytic pathway. METHODS: Whole-exome sequencing was used in 14 patients with systemic JIA and MAS and in their parents to identify protein-altering single-nucleotide polymorphisms/indels in known HLH-associated genes...
