421 Possible Causes for Anaphylaxis, T Cell Activation Increased

  • Hypersensitivity

    However, increased activation of CD4 T-cell and CD8 T-cells was only observed following four days of DDAB exposure.[ncbi.nlm.nih.gov] This review highlights some of the research advances in anaphylaxis and hypersensitivity reactions to foods, drugs, and insects and in allergic skin disease that were reported[ncbi.nlm.nih.gov] Read more… Why is Anaphylaxis Awareness Week Important? In our 25th anniversary year, the Anaphylaxis Campaign needs your support more than ever.[anaphylaxis.org.uk]

  • Food Allergy

    The purpose of the campaign is to raise awareness of the sharp increase of anaphylaxis, especially in children.[web.archive.org] Memory T cells are increased in frequency and have distinct activation requirements and cell-surface proteins that distinguish them from armed effector T cells 10-25.[ncbi.nlm.nih.gov] Key words Food allergy anaphylaxis quality of life children adolescents adults Abbreviations AAI Adrenaline autoinjector AGATE Arbeitsgemeinschaft Anaphylaxie Training und[doi.org]

  • Atopy

    It is hypothesized that an overwhelming T-cell activity that produces this aberrant lymphokine profile limits cellular immune response.[hawaii.edu] In very rare cases, anaphylaxis can occur. Cyclosporine is a drug that is most often used in organ transplants to prevent rejection.[wagwalking.com] Most cases of anaphylaxis associated with MMR vaccines were related to the content of gelatin, which was used as a stabilizer before 1998.[worldallergy.org]

  • Atopic Dermatitis

    These early effects lead to increased histamine release from IgE-activated mast cells and elevated activity of the T-helper cell–mediated immune system.[emedicine.com] Dermatologists should be aware of the possibility of anaphylaxis or other allergic hypersensitivity in response to corticosteroids.[ncbi.nlm.nih.gov] […] at the end of treatment'; 'Participant- or parent-reported specific symptoms of eczema, by subjective measures'; and 'Adverse events, such as acute episodes of asthma or anaphylaxis[ncbi.nlm.nih.gov]

  • Substance Abuse Problems

    The immune system actively attempts to replenish the lost T cells, which also subsequently become infected by the virus.[americanaddictioncenters.org] This chronic response may be due in part to an increased, system-wide bacterial load resulting from the decreased vigilance of a weakened immune system.[americanaddictioncenters.org]

  • Drug Hypersensitivity

    Areas covered: This article reviews the pathways of T-cell activation by drugs and how the ever increasing number of associations between expression of HLA alleles and susceptibility[ncbi.nlm.nih.gov] The clinical presentation of drug hypersensitivity reactions ranges from mild cutaneous reactions to life-threatening symptoms including anaphylaxis.[ncbi.nlm.nih.gov] Mastocytosis in adults is associated with a history of anaphylaxis in 22-49%.[ncbi.nlm.nih.gov]

  • Urticaria

    We report four patients with severe antihistamine-resistant CSU, who developed angioedema, anaphylaxis and/or flare up of urticaria at different times following omalizumab[ncbi.nlm.nih.gov] cell activation.[frontiersin.org] In rare cases, hives are part of a severe allergic reaction, called anaphylaxis.[hopkinsmedicine.org]

  • Systemic Mastocytosis

  • Hypogammaglobulinemia

    These increased memory T cells overexpressed activation markers such as CD69, CD95, and HLA-DR.[ncbi.nlm.nih.gov] Blood product reactions History of anaphylaxis or other severe reactions following transfusion of blood products may indicate an underlying IgA deficiency, although this is[emedicine.medscape.com] Immunoglobulin is also associated with a number of other side effects detailed further in the article, and is contraindicated in any patient known to experience anaphylaxis[dbpedia.org]

  • Selective IgA Immunodeficiency

    […] while other activation/differentiation markers on T cells (including the expression of CD45RA and CD45RO antigens) were not changed.[ncbi.nlm.nih.gov] Patients with selective IgA deficiency are advised to wear an identification bracelet to prevent inadvertent plasma or immune globulin administration, which could lead to anaphylaxis[merck.com] Timely decisions regarding further transfusion management of patients experiencing anaphylaxis often rely upon more rapidly obtained assays of the IgA concentration as an[ncbi.nlm.nih.gov]
