Allergic skin disease

C Incorvaia, C Cavaliere, F Frati, S Masieri
Allergic rhinitis (AR) was long considered a quite trivial disease, but the advance in epidemiological and clinical knowledge, with a major role for Allergic rhinitis and its Impact on Asthma (ARIA) initiative, substantially changed the scene. Now we know that AR has significant effects on patients’ quality of life and also has a relevant economic burden. The ARIA phenotypes related to the duration of symptoms and to the severity of AR are very useful in establishing the optimal strategy in each patient with AR, also according to the kind of allergens that cause rhinitis...

The introduction of highly purified natural and recombinant single allergenic molecules represented an important improvement in the diagnosis of IgE sensitization. The identification of specific IgE against cross-reacting molecules such as profilin, lipid transfer proteins, calcium binding proteins or against “genuine molecules”, represents an added value and allows to distinguish between true and false polysensitization. In vitro tests add information to recognize patients with sensitization to genuine molecules that cause allergic diseases and to evaluate in childhood the spreading of sensitization for each molecule in order to choose the best treatment and to identify the ideal patient for allergen immunotherapy...

The skin prick test (SPT) is the most common test for the diagnosis of allergy. SPT is performed by pricking the skin, usually in the volar surface of the forearm, with a lancet through a drop of an allergen extract and is usually the first choice test in the diagnostic workup for allergic diseases because of its reliability, safety, convenience and low cost. SPT is minimally invasive and has the advantage of testing multiple allergens in 15 to 20 min. In children, SPT is far less disturbing than venipuncture and is used to obtain a sample of serum to measure specific IgE through in vitro tests...

BACKGROUND: Prenatal environmental phenol and phthalate exposures may alter immune or inflammatory responses leading to respiratory and allergic disease. OBJECTIVES: We estimated associations of prenatal environmental phenol and phthalate biomarkers with respiratory and allergic outcomes among children in the Mount Sinai Children's Environmental Health Study. METHODS: We quantified urinary biomarkers of benzophenone-3, bisphenol A, paradichlorobenzene (as 2,5-dichlorophenol), triclosan, and 10 phthalate metabolites in third trimester maternal samples and assessed asthma, wheeze, and atopic skin conditions via parent questionnaires at ages 6 and 7 years (n = 164 children with 240 observations)...

Corticosteroids are potent anti-inflammatory and anti-allergic agents used in the treatment of various inflammatory diseases, including allergic disease. They are frequently considered the therapy-of-choice for many skin diseases. However, allergic reactions caused by corticosteroids have been reported. Among these, delayed reactions to topical steroids are more common, whereas immediate reactions to systemic steroids are rare. Herein, we report the case of a 32-year-old woman with triamcinolone-induced immediate hypersensitivity reaction, in which the patient had a positive prick test result with triamcinolone...

The incidence of atopic diseases, including atopic dermatitis (AD), food allergies, allergic rhinitis, and asthma, has increased in recent decades, and currently affects approximately 20% of the population. Atopic march is the development of AD in infancy and subsequent food allergies, allergic rhinitis, and asthma in later childhood. Patients with infantile eczema may develop typical symptoms of AD, allergic rhinitis, and asthma at certain ages. Some patients' symptoms persist for several years, whereas others may have resolution with aging...

Atopic dermatitis (AD) is a common, highly pruritic, chronic inflammatory skin disease. Dysfunction of the epidermal barrier is witnessed by an increased transepidermal water loss in lesional and non-lesional AD skin. The inflammation in lesional AD skin is well characterized. Non-lesional skin of AD patients shows histological signs of a subclinical inflammation and a pro-inflammatory cytokine milieu. This microinflammation is present even in seemingly healed skin and must be taken into account regarding treatment of AD...

Allergic contact dermatitis and its animal model, contact hypersensitivity (CHS), are T cell-mediated inflammatory skin diseases that require activation of the innate immune system. Here we investigate the role of innate lymphoid cells (ILCs) during the elicitation phase of TNCB-induced CHS using EomesGfp/+ x Rorc(γt)-CreTg x Rosa26RYfp/+ reporter mice. Ear swelling responses, cutaneous ILC numbers and cytokine production were determined at different time points. Functional analyses were performed in a CD90...

OBJECTIVE: Contact dermatitis (CD) is a common disease seen by allergists. Although underutilized, patch testing (PT) remains the gold standard in the diagnosis of allergic CD. It is not difficult to perform, however, the interpretation of the PT, proper classification of the results and determination of their relevance, need an appropriate level of expertise. The objective of this article is to provide a review of CD and its key allergens and provide updates and recommendations for the practicing allergist...

Allergies are complex diseases that result from interactions between multiple genetic and environmental factors. However, the increase in allergies observed in the past decades is explained exclusively by environmental changes occurring in the same period. Presently, the exposome, the totality of specific and nonspecific external environmental exposures (external exposome) to which a subject is exposed from preconception onward and their consequences at the organ and cell levels (internal exposome), is being considered to explain the inception, development, and exacerbations of allergic diseases...

BACKGROUND: Egg allergy is phenotypically heterogeneous. A subset of egg allergic individuals can tolerate egg in an extensively heated form. Inclusion of baked-egg (BE) into their diet accelerates resolution of egg allergy. Conversely, BE reactivity is associated with persistent disease. The immune basis of this clinical heterogeneity is unknown. OBJECTIVES: To study egg-specific antibody, basophil, and T cell responses in children with reactivity or tolerance to BE...

Atopic dermatitis (AD) is a chronic inflammatory skin disease involving Th2 cells, eosinophils, and mast cells. Although CCR4 is a major chemokine receptor expressed on Th2 cells and regarded as a potential therapeutic target for allergic diseases, its role in AD still remains unclear. Here, by using a hydrogel patch as a transcutaneous delivery device for ovalbumin (an antigen) and Staphylococcus aureus δ-toxin (a mast cell activator), we efficiently induced acute AD-like skin lesions in BALB/c mice, a strain prone to Th2 responses, that were characterized by (1) increased numbers of eosinophils, mast cells, and CCR4-expressing Th2 cells in the skin lesions, (2) elevated levels of total and ovalbumin-specific IgE in the sera, and (3) increased expression of IL-4, IL-17A, IL-22, CCL17, CCL22, and CCR4 in the skin lesions...

Allergic contact dermatitis (ACD) is a common irritability skin disease, which can be cured by using the Chinese patent medicine. To explore the pharmacological effect of total flavonoids of Fructus Kochiae (FK) on ACD, we used dinitrochlorobenzene- (DNCB-) induced ACD rats. Five groups were used in our experiments. The normal group and the DNCB group were treated with 0.5% CMC-Na; the DNCB + hFK group was treated with a high dose of total flavonoids of FK (200 mg/kg); the DNCB + lFK group was treated with a low dose of FK (100 mg/kg); the DNCB + Pre group was treated with prednisolone acetate (2...

Atopic dermatitis is an allergic inflammatory skin disease characterized by the production of the type 2 cytokines in the skin by type 2 innate lymphoid cells (ILC2s) and T helper 2 (TH 2) cells, and tissue eosinophilia. Using two distinct mouse models of atopic dermatitis, we show that expression of retinoid-related orphan receptor α (RORα) in skin-resident T regulatory cells (Tregs ) is important for restraining allergic skin inflammation. In both models, targeted deletion of RORα in mouse Tregs led to exaggerated eosinophilia driven by interleukin-5 (IL-5) production by ILC2s and TH 2 cells...

Children with atopic dermatitis (AD) usually develop symptoms when they reach the age of 6-7 years, but the risk of developing respiratory allergies, asthma and allergic rhinitis (AR) remains high. In most children with AD, the development of asthma and AR is associated with sensitization to food allergens and/or aeroallergens, while only a small percentage missed atopic diathesis. In about 35% of children with AD, food allergy is the provoking cause, and 60% of infants who had AD in the first 3 months of life were sensitized against aeroallergens by the age of 5...

BACKGROUND AND PURPOSE: Non-allergic angio-oedema is a life threatening disease mediated by activation of bradykinin type 2 receptors (B2). The aim of this study was to investigate whether activation of B2 by endogenous bradykinin contributes to physiologic extravasation. This may shed new light on the assumption that treatment with an ACEi results in an alteration of the vascular barrier function predisposing to non-allergic angio-edema. EXPERIMENTAL APPROACH: We generated a new transgenic mouse model characterized by endothelium-specific overexpression of B2 (B2tg ) and established a non-invasive two-photon laser microscopy approach to measure the kinetics of spontaneous extravasation in-vivo...
