Bee venom is a blend of biochemicals ranging from small peptides and enzymes to biogenic amines. It is capable of triggering severe immunologic reactions owing to its allergenic fraction. Venom components are presented to the T cells by antigen-presenting cells within the skin. These Th2 type T cells then release IL-4 and IL-13 which subsequently direct B cells to class switch to production of IgE. Generating venom-specific IgE and crosslinking FcεR1(s) on the surface of mast cells complete the sensitizing stage in allergic individuals who are most likely to experience severe and even fatal allergic reactions after being stung...

More than 40% of allergic patients suffer from grass pollen allergy. Phl p 1, the major timothy grass pollen allergen, belongs to the cross-reactive group 1 grass pollen allergens that are thought to initiate allergic sensitization to grass pollen. Repeated allergen encounter boosts allergen-specific IgE production and enhances clinical sensitivity in patients. To investigate immunological mechanisms underlying the boosting of allergen-specific secondary IgE Ab responses and the allergen epitopes involved, a murine model for Phl p 1 was established...

BACKGROUND: Ragweed (Ambrosia artemisiifolia) and mugwort (Artemisia vulgaris) are the major cause of pollen allergy in late summer. Allergen-specific lymphocytes are crucial for immune modulation during immunotherapy. We sought to generate and pre-clinically characterise highly immunogenic domains of the homologous pectate lyases in ragweed (Amb a 1) and mugwort pollen (Art v 6) for immunotherapy. METHODS: Domains of Amb a 1 (Amb a 1α) and Art v 6 (Art v 6α) and a hybrid molecule, consisting of both domains, were designed, expressed in E...

Fungi cause more than a billion skin infections, more than 100 million mucosal infections, 10 million serious allergies and more than a million deaths each year. Global mortality owing to fungal infections is greater than for malaria and breast cancer and is equivalent to that owing to tuberculosis (TB) and HIV. These statistics evidence fungal infections as a major threat to human health and a major burden to healthcare budgets worldwide. Those patients who are at greatest risk of life-threatening fungal infections include those who have weakened immunity or have suffered trauma or other predisposing infections such as HIV...

Mast cells (MCs) are mediators of allergy and inflammation and participate in the growth of cancer cells. MCs can promote both neoangiogenesis and tumor growth. They increase in the stroma of certain tumors where they can be recruited by tumor-derived chemoattractants, such as monocyte chemotactic protein-1 (MCP-1), RANTES and stem cell factor (SCF) to selectively secrete inflammatory molecules including chemical mediators and cytokines (TNF, IL-6 and IL-1). However, MC differentiation pathways and heterogeneity in cancer are still poorly understood...

During the last two decades, hyper-immunoglobulin (Ig)E syndromes have been characterized clinically and molecularly in patients with genetically determined primary immunodeficiencies. However, the detection of low IgE levels, defined here as below detection limit in the routine clinical immunology laboratory, has received little attention. We analysed the association of serum IgA, IgM and IgG levels (including IgG subclasses) with low, normal or high serum IgE levels in patients evaluated in a single-centre out-patient immunodeficiency and allergy clinic...

BACKGROUND: For causal treatment by allergy immunotherapy (AIT) a single or few allergen products for the clinically most relevant allergens are applied to treat multiple allergies, but few data on the tolerability of multiple AIT applications are available. OBJECTIVE: The aim of our study was to investigate safety and tolerability in patients treated by subcutaneous immunotherapy (SCIT) and concomitant SCIT or sublingual immunotherapy (SLIT) products. METHODS: In a non-interventional, observational study in Germany treatment of patients with a primary SCIT and concomitant AIT (SCIT or SLIT) was documented during the first 4 months of treatment...

Rapid changes in modern medicine along with advances in the science of learning and memory have necessitated a shift in the way physician knowledge is assessed. Physician recertification beyond initial certification has historically consisted of retaining large amounts of knowledge over a long time span. The adult learning theory has shown that the maintenance and improvement of our knowledge base is more effective by being exposed to new concepts at regular intervals throughout one's career and reinforcing these concepts on an ongoing basis...

BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDS) are among the most common causes of drug hypersensitivity (HS) reactions. The diagnosis is based on a careful clinical history, and provocation tests are considered the gold standard for diagnosis. Skin tests have some value to study reactions to pyrazolones. Laboratory investigations are mostly used for research purposes. Different phenotypes have been described. OBJECTIVE AND METHODS: Our aim was to describe the most common clinical manifestations of NSAID HS in a large population of adult patients, the drugs involved, the association with previously described risk factors, and the outcome of diagnostic procedures...

Immunotherapy for peanut allergy has been an exploding topic of study within the last few years. Sublingual, epicutaneous, and oral immunotherapy are being investigated and show promise in the treatment of peanut allergy. Oral immunotherapy has shown the most clinical benefit; however, sublingual and epicutaneous immunotherapy appear to have the most favorable safety profiles. Most studies to date suggest that only a minority of subjects achieve sustained unresponsiveness to peanut after discontinuation of immunotherapy...

Th2 immunity and allergic immune surveillance play critical roles in host responses to pathogens, parasites and allergens. Numerous studies have reported significant links between Th2 responses and cancer, including insights into the functions of IgE antibodies and associated effector cells in both anti-tumour immune surveillance and therapy. The interdisciplinary field of AllergoOncology was given Task Force status by the European Academy of Allergy and Clinical Immunology in 2014. Affiliated expert groups focus on the interface between allergic responses and cancer, applied to immune surveillance, immunomodulation and the functions of IgE-mediated immune responses against cancer, to derive novel insights into more effective treatments...

BACKGROUND: Probiotics constitute the viable and beneficial microbes, which offer a dietary means to sustain the balance of gastro-intestinal (GI) microflora. Owing to their multiple health benefits, these have recently gained wide attention among researchers for exploring their potential in safeguarding the health of humans and animals. Probiotics could also modulate host-immune responses, thereby help in counteracting the immunological dysfunctions. Probiotics can inhibit the systemic invasion of pathogens entering through the GI mucosa/ oral cavity and have been found to possess effective prophylactic and therapeutic utilities against various infectious pathogens as well as non-infectious diseases and disorders...

Asthma affects an estimated 7 million children and causes significant health care and disease burden. The most recent iteration of the National Heart, Lung and Blood Institute asthma guidelines, the Expert Panel Report 3, emphasizes the assessment and monitoring of asthma control in the management of asthma. Asthma control refers to the degree to which the manifestations of asthma are minimized by therapeutic interventions and the goals of therapy are met. Although assessment of asthma severity is used to guide initiation of therapy, monitoring of asthma control helps determine whether therapy should be maintained or adjusted...
