Objectives We aimed to evaluate the relationship between nasal eosinophilia and nasal hyperresponsiveness to allergen extract. Study Design Retrospective chart review. Setting Academic tertiary rhinologic practice. Subjects and Methods We performed allergy tests (skin prick test and multiple allergosorbent test) and nasal cytology for 194 patients with rhinitis symptoms (76 males and 118 females; age, 11-69 years). According to the results, they were classified into 4 groups: group A (allergic rhinitis with eosinophilia, n = 26), group B (allergic rhinitis without eosinophilia, n = 77), group C (nonallergic rhinitis with eosinophilia syndrome, n = 20), and group D (nonallergic rhinitis without eosinophilia, n = 71)...

Airway fibrosis is a prominent feature of asthma, contributing to the detrimental consequences of the disease. Fibrosis in the airway is the result of collagen deposition in the reticular lamina layer of the subepithelial tissue. Myofibroblasts are the leading cell type involved with this collagen deposition. Established methods of collagen deposition quantification present various issues, most importantly their inability to quantify current collagen biosynthesis occurring in airway myofibroblasts. Here, a novel method to quantify myofibroblast collagen expression in asthmatic lungs is described...

Atopic dermatitis (AD) is a common chronic inflammatory skin disorder afflicting from infancy to adults with itching, scratching, and lichenification. We aimed to investigate the effects of esculetin from Fraxinus rhynchophylla on atopic skin inflammation. For induction of atopic skin inflammation, we exposed the ears of female BALB/c mice to house dust mite (Dermatophagoides farinae extract, DFE) and 2,4-dinitrochlorobenzene (DNCB) for 4 weeks. Oral administration of esculetin reduced the symptoms of DFE/DNCB-induced atopic skin inflammation, which were evaluated based on ear swelling and number of scratch bouts...

Background Allergic rhinitis is the most common allergic disorder. Although the management of the disease is successful in many patients, based on guidelines, some of them remain with symptoms uncontrolled with pharmacotherapy. Presently, there is no substantiated information on the control of allergic rhinitis in patients who underwent sublingual immunotherapy. Objective The purpose of this prospective follow-up study was to assess the control of allergic rhinitis in adults after a three-year course of house dust mite sublingual immunotherapy...

Airway eosinophilic inflammation is a key feature of type 2-high asthma. The role of epithelial miRNA in airway eosinophilic inflammation remains unclear. We examined the expression of miR-221-3p in bronchial brushings, induced sputum and plasma from 77 symptomatic, recently diagnosed steroid-naïve subjects with asthma and 36 healthy controls by quantitative PCR, and analyzed the correlation between miR-221-3p expression and airway eosinophilia. We found that epithelial, sputum and plasma miR-221-3p expression was significantly decreased in subjects with asthma...

Background: Cats are the major source of indoor inhalant allergens after house dust mites. The global incidence of cat allergies is rising sharply, posing a major public health problem. Ten cat allergens have been identified. The major allergen responsible for symptoms is Fel d 1, a secretoglobin and not a lipocalin, making the cat a special case among mammals. Main body: Given its clinical predominance, it is essential to have a good knowledge of this allergenic fraction, including its basic structure, to understand the new exciting diagnostic and therapeutic applications currently in development...

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by highly pruritic, erythematous, and eczematous skin plaques. We previously reported that phospholipase A2 (PLA2) derived from bee venom alleviates AD-like skin lesions induced by 2,4-dinitrochlorobenzene (DNCB) and house dust mite extract ( Dermatophagoides farinae extract, DFE) in a murine model. However, the underlying mechanisms of PLA2 action in actopic dermatitis remain unclear. In this study, we showed that PLA2 treatment inhibited epidermal thickness, serum immunoglobulin E (IgE) and cytokine levels, macrophage and mast cell infiltration in the ear of an AD model induced by DFE and DNCB...

Using the terminology for Dermatophagoides pteronyssinus, IgE responses to house dust mites have been shown to be mostly directed to the serodominant Der p 1, 2 and 23 allergen components with mid -tier responses to Der p 4, 5, 7 and 21 that are made by 30-50% of subjects with titers proportional to those of the serodominant specificities. This pattern can be seen to evolve in childhood and although responses to minor allergens appear to contribute little to the total IgE they are at least markers for a greater propensity to develop disease...

Human IgE against helminths is a normal component of the whole protective response elicitesd during infection, when specific IgE to a great number of antigens is produced; however, few of those IgE binding components are actually allergens. In general, considering the strong Th2/IgE responses during helminth infections is intriguing that they are not usually associated with allergic symptoms, which probably (but not exclusively) depends on parasite-induced immunomodulation. However, allergic manifestations have been described during some helminth infections such as ascariasis, strongyloidiasis, anisakiasis and hydatidosis...

BACKGROUND: Studies of potential adverse effects of traffic related air pollution (TRAP) on allergic disease have had mixed findings. Nutritional studies to examine whether fish oil supplementation may protect against development of allergic disease through their anti-inflammatory actions have also had mixed findings. Extremely few studies to date have considered whether air pollution and dietary factors such as fish oil intake may interact, which was the rationale for this study. METHODS: We conducted a secondary analysis of the Childhood Asthma Prevention Study (CAPS) birth cohort, where children were randomised to fish oil supplementation or placebo from early life to age 5 years...

AIM: House dust mite (HDM) allergens are important elicitors of IgE-mediated allergies. This study was aimed at constructing and characterizing a recombinant fusion protein, DpTTDp, which was based on carrier-bound Der p 1-derived peptides for HDM allergen immunotherapy. METHODS: Using the Immune Epitope Database (IEDB), we identified from Der p 1, a 34-mer hypoallergenic peptide. Two copies of the hypoallergen were then fused to a partial fragment of a tetanus toxoid molecule's N-and C terminus and expressed in Escherichia coli...

Allergen immunotherapy has been shown to be effective in treatment of allergic rhinitis (AR). Sublingual immunotherapy (SLIT) is generally recommended for treating seasonal AR in adults and children; however, questions remain in regard to AR treatment in relation to house dust mite (HDM). Due to heterogeneous formulations, different outcome reporting systems, and the lack of a standardized dose, HDM SLITs have not been standardized in published studies. Nevertheless, studies continuously report positive effects of HDM SLIT in AR, and HDM SLIT remains a treatment option for patients with HDM-induced allergic asthma that frequently co-exists with AR...
