Krzysztof Rutkowski, Clive E H Grattan
Chronic urticaria (CU) is a disease characterised by pruritic weals, angio-oedema or both occurring for at least 6 weeks. It encompasses spontaneous and inducible urticarias. The national and international guidelines outline the principles of treatment. Omalizumab, an anti-immunoglobulin E monoclonal antibody has transformed the management of many severe and treatment-refractory patients. However, current UK guidance on its use does not address the needs of those with less severe disease, inducible urticarias, idiopathic histaminergic angio-oedema without weals as a presentation of CU and omalizumab non-responders...

During childhood, exacerbation of asthma is the most common medical reason for admission to hospital in the UK. Each year 44,000 children are admitted to hospital in the UK with 40-50 children dying as a result of asthma [1]. Weather patterns and seasonality have distinct, measurable effects on the rates of hospitalisation for asthma. This article is protected by copyright. All rights reserved.

BACKGROUND: We have previously shown that maternal cow's milk (CM) elimination results in down-regulation of CM-specific IgA antibody levels in BM, but not in serum, suggesting that an entero-mammary link may exist for food-specific antibody-secreting cells. OBJECTIVE: We sought to investigate whether food-specific IgA epitope profiles differ intra-individually between mother's serum and BM. We also examined how infants' food epitope-specific IgA develops in early infancy and the relationship of IgA epitope recognition with development of cow's milk allergy (CMA)...

BACKGROUND: Human airway smooth muscle cells (ASMCs) may have a pro-inflammatory role through the release of inflammatory mediators. Increasing evidence indicates that human β-defensins (HBDs) are related to pathogenesis of asthma. OBJECTIVES: To examine the plasma level of HBD-1, -2 and -3 in asthmatic patients and the expression of their mouse orthologs in the lung tissue of a mouse model of chronic severe asthma. Further to investigate the effect of HBD-3 on the release of the pro-inflammatory cytokine IL-8 and to explore the mechanisms...

In the 21st century, the heterogeneity of asthma and allergic diseases in childhood will be characterized by multiple phenotypes related to different pathophysiologic pathways or endotypes. From a medical point of view, improved understanding of disease etiology and mechanisms will lead to optimal management including personalized targeted treatment.

Ricardo J Saranz, Alejandro Lozano, Natalia A Lozano, Marina F Ponzio, Álvaro A Cruz
The upper and lower airways behave as a physiological and pathophysiological unit. Subclinical lower airways abnormalities have been described in patients with rhinitis without asthma. These are expressed as bronchial hyperreactivity, abnormalities in lung function and bronchial inflammation, likely as a result of the same phenomenon with systemic inflammatory impact that reaches both the nose and the lungs, which for unknown reasons does not always have a full clinical expression. Patients with rhinitis are at increased risk of developing asthma; therefore most authors suggest a careful clinical evaluation and monitoring of these patients, especially if symptoms related to inflammation in the lower airways are observed...

Allergic Rhinitis (AR) affects up to one third of the adult population and causes illness and disability worldwide.[1] Main symptoms include sneezing, rhinorrhea and nasal obstruction. AR is often accompanied with conjunctivitis, characterised by watery, itchy and sometimes red or swollen eyes. House Dust Mite (HDM) allergens are one of the most relevant indoor allergy triggers.[2] Treatment of AR consists of symptomatic medications (mainly antihistamines and nasal corticosteroids) and allergen specific immunotherapy (in more severe cases)...

BACKGROUND: Concurrent sensitization to peanut (PN) and tree nuts (TN), the most dangerous food allergies, is common. Current oral immunotherapy (OIT) is not fully satisfactory. OBJECTIVE: To determine if the herbal formula B-FAHF-2 (BF2) ameliorates PN/TN OIT adverse reactions and enhances persistence of a tolerant state. METHODS: Concurrently sensitized peanut, walnut (WN) and cashew (CSH) allergic mice received 1 day PN/WN/CSH rush OIT plus 3 weeks of maintenance dosing, with or without 3-weeks prior and 3-weeks BF2 co-treatment...

BACKGROUND: The major trigger of asthma exacerbations is infection with a respiratory virus, most commonly rhinovirus. Type 2 inflammation is known to be associated with an increased risk of exacerbations in general. Whether type 2 inflammation at baseline increases the risk of future virus-induced exacerbations is unknown. OBJECTIVE: To assess whether type 2 inflammation is associated with an increased risk of virus-induced exacerbations of asthma. METHODS: Stable asthmatics had spirometry, skin prick test, measurement of FeNO and sputum induced for differential cell counts...

BACKGROUND: IL-5 causes suspended eosinophils to polarize with filamentous (F)-actin and granules at one pole and the nucleus in a specialized uropod, the "nucleopod", which is capped with P-selectin glycoprotein ligand-1 (PSGL-1). IL-5 enhances eosinophil adhesion and migration on periostin, an extracellular matrix protein upregulated in asthma by type 2 immunity mediators. OBJECTIVE: Determine how the polarized morphology evolves to foster migration of IL-5-stimulated eosinophils on a surface coated with periostin...

BACKGROUND: Processed foods are part of daily life. Almost all processed foods contain food additives such as sweeteners, preservatives and colourants. From childhood, it is difficult to avoid consuming food additives. It is thought that oral tolerance for food antigens is acquired during early life. If tolerance fails, adverse immune responses to food proteins may occur. OBJECTIVE: We hypothesised that food additives prevent acquisition of oral tolerance and aimed to verify the safety of food additives...

In the randomized, controlled study Probiotics in the Prevention of Allergy among Children in Trondheim (ProPACT), maternal probiotic supplementation reduced the incidence of atopic dermatitis (AD) in the offspring. In the current study, we hypothesized that the effect was mediated by a shift in the T helper (Th) cells in the children. OBJECTIVE: To examine whether Th cell proportions were affected by maternal probiotic supplementation and thus could mediate the preventive effect of probiotics on AD...

BACKGROUND: Microarray-based component-resolved diagnostics (CRD) has become an accepted tool to detect allergen specific IgE-sensitization towards hundreds of allergens in parallel from one drop of serum. Nevertheless specificity and sensitivity as well as a simultaneous detection of allergen specific IgG4, as a potential parameter for tolerance development, remain to be optimized. OBJECTIVE: We applied the recently introduced silicon chip coated with a functional polymer named copoly(DMA-NAS-MAPS) to the simultaneous detection of food allergen specific IgE and IgG4, and compared it with ImmunoCAP and ImmunoCAP ISAC...

BACKGROUND: Genetic markers of susceptibility to asthma exacerbations in adults remain unclear. OBJECTIVE: To identify genetic markers of asthma exacerbations, particularly in patients with type-2 inflammatory endotype. METHODS: In this observational study of patients enrolled in the Kinki Hokuriku Airway disease Conference multicenter study, frequency of exacerbations requiring systemic corticosteroids during 2 years after enrolment and associated risk factors were determined...

BACKGROUND: Nickel (Ni) is the most frequent metal allergen and induces a TH1 -dependent type-IV allergy. Although Ni(2+) is considered to bind to endogenous proteins, it currently remains unclear whether these Ni-binding proteins are involved in Ni allergy in vivo. We previously reported the adjuvant effects of lipopolysaccharide (LPS) in a Ni allergy mouse model. Since LPS induces a number of inflammatory mediators, we hypothesized that Ni-binding protein(s) are also induced by LPS...

BACKGROUND: Allergy to the German cockroach (Blattella germanica) is a significant asthma risk factor for inner-city communities. Cockroach, like other allergens, contains trypsin-like enzyme activity that contributes to allergenicity and airway inflammation by activating proteinase-activated receptors (PARs). To date, the enzymes responsible for the proteolytic activity of German cockroach allergen have not been characterized. OBJECTIVES: We aimed to identify, isolate and characterize the trypsin-like proteinases in German cockroach allergen extracts used for clinical skin tests...

Perinatal use of Lactobacillus GG (LGG) has been associated with fewer allergic diseases, mainly eczema in high-risk children at the age of two years [1,2], a phenomenon still seen at 6-9 years [2-5]. We reported earlier that in high-risk children pre- and postnatal use of a mixture of probiotics reduced the incidence of atopic eczema at two years of age, and during the first five years atopic eczema reduction was seen in Caesarean-delivered children but not in the whole cohort [1,6]. Mothers were recruited during pregnancy and randomized at 35 weeks of gestation to the probiotic or placebo group...

BACKGROUND: We previously reported that exposure to a farming environment is allergy-protective, while high proportions of neonatal immature/naïve CD5(+) B cells and putative regulatory T cells (Tregs) are risk factors for development of allergic disease and sensitization up to 3 years of age. OBJECTIVE: To examine if B- and T-cell maturation are associated with allergic disease and farming environment over the first 8 years in life. METHODS: In the prospective FARMFLORA study, including both farming and non-farming families, 48 out of 65 children took part in the 8-year follow-up study...

BACKGROUND: The precautionary allergen labelling (PAL) and Voluntary Incidental Trace Allergen Labelling (VITAL(®) ) tools were designed by industry to assist consumers with selecting safe foods for consumption. However, a sizeable proportion of food products bear no label and it is unclear whether these products are free from allergens and therefore safe to consume or have simply not undergone a risk assessment and therefore remain unlabelled for that reason. OBJECTIVE: To assess the prevalence of unlabelled products that have undergone a risk assessment process and to examine the factors influencing industry's uptake of the VITAL(®) process...

BACKGROUND: Mesenchymal stem cells (MSCs) have multiple immunomodulatory properties and hold therapeutic potential for inflammatory diseases. However, the therapeutic and immunologic effects of human umbilical cord blood-derived MSCs (huMSCs) remain largely unexamined for asthma. OBJECTIVE: This study was to investigate the immunomodulatory properties of huMSCs in an ovalbumin (OVA)-induced murine asthma model. METHODS: Mice were injected intraperitoneally with OVA and an aluminum hydroxide adjuvant...
