BACKGROUND: Shrimp sensitization is common in the general population, but the presence of symptoms is only moderately related to sensitization. A point still at issue is which in vivo and/or in vitro tests (food challenge, component-resolved diagnosis, house dust mite [HDM] sensitization) can help in distinguishing shrimp-allergic subjects from subjects that are sensitized but tolerant. METHODS: The aim of this study was to evaluate the role of IgE to the different shrimp and mite allergens in distinguishing shrimp challenge-positive from challenge-negative patients...

BACKGROUND: Fructo-oligosaccharides (FOS) are prebiotic agents with immunomodulatory effects involving improvement of the intestinal microbiota and metabolome. In this study, we investigated the cellular mechanisms through which FOS modulate intestinal antigen-specific CD4+ T cell responses in food allergy, using OVA23-3 mice. METHODS: OVA23-3 mice were fed an experimental diet containing either ovalbumin (OVA) or OVA and FOS for 1 week. Body weight and mucosal mast cell protease 1 in the serum were measured as the indicator of intestinal inflammation...

BACKGROUND: Endobronchial valve (EBV) placement is an established lung volume reduction procedure aiming to improve lung function and exercise capacity in patients with severe emphysema. As EBVs consist of silicone and nitinol (a metal alloy of nickel and titanium), there are concerns that nickel ions might be released and could have a clinical impact in patients with a contact allergy to nickel. Based on a case with hypersensitivity pneumonitis (HP) after treatment with EBVs, we aimed to evaluate the in vitro nickel release from EBVs using inductively coupled plasma mass spectrometry (ICP-MS) and scanning electron microscopy (SEM)...

BACKGROUND: Expression levels of cytokine and growth factor receptors have been found to be important in the regulation of their action. Tumor necrosis factor-α (TNFα) is actively involved in inflammation processes in atopic dermatitis (AD), but the role of TNFα membrane receptors (TNFR) and their regulatory function in AD remains unclear. AIM: We aimed to determine the associations of parameters of TNFRα expression on immunocompetent cells with disease severity before and after therapy in AD patients...

BACKGROUND: Dendritic cells (DCs) are the sentinels of the immune system. Upon recognition of a pathogen, they mature and migrate to draining lymph nodes to prime and polarize T cell responses. Although it is known that helminths and helminth-derived molecules condition DCs to polarize T helper (Th) cells towards Th2, the underlying mechanisms remain incompletely understood. OBJECTIVES: The aim of this study was to conduct a proteome analysis of helminth antigen-stimulated DCs in order to gain more insight into the cellular processes associated with their ability to polarize immune responses...

BACKGROUND: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is an inflammatory disease associated with lymphoid aggregates and local IgE production related to Staphylococcus aureus enterotoxins. T-follicular helper cells and their effector cytokine interleukin (IL)-21 play an important role in germinal center proliferation. METHODS: IL-21 was determined on the mRNA level by qPCR in nasal tissue of 3 groups of patients: control (n = 17), chronic rhinosinusitis without nasal polyposis (CRSsNP; n = 23), and CRSwNP (n = 35)...

BACKGROUND: Skin test reactivity to hymenoptera venom and venom-specific IgE are important for diagnosing venom allergy and deciding on the appropriate allergen for venom immunotherapy (VIT). Longitudinal data on skin test reactivity during VIT and their correlation with venom-specific immunoglobulin (Ig)E and IgG are scarce. METHODS: We retrospectively analyzed shifts in skin test reactivity and serum levels of venom-specific IgE and IgG in patients allergic to hymenoptera venom before the initiation of VIT with ultrarush therapy and after ≥3 years of VIT...

In a previous study, we reported that interleukin-4 production was reduced in spleen cells of mice administered 3,5,6,7,8,3',4'-heptamethoxyflavone (HMF), which is a polymethoxyflavone found at high concentrations in the peel of various citrus fruits. In this study, we investigated the function of HMF on the growth of T cells cultured from the spleens of mice. HMF decreased the reduction of 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) by anti-CD3/CD28 antibody-stimulated mouse spleen cells...

BACKGROUND: Oaks are the most common trees in Korean forests, and Mongolian oak, Quercus mongolica, is the dominant species. However, no allergen has been characterized from Mongolian oak. In this study, we tried to characterize a major allergen from Mongolian oak. METHODS: A molecule homologous to pathogenesis-related 10 (PR-10)-like protein, Que m 1, was cloned by RT-PCR. Its recombinant protein, along with Que a 1, an allergen from white oak (Q. alba), was produced...

BACKGROUND: The efficacy and safety of allergen-specific immunotherapy (AIT) are highly dose-dependent. METHODS: We investigated the dosage effects of AIT and the underlying mechanisms in a murine model of shrimp hypersensitivity. BALB/c mice were sensitized with recombinant shrimp allergen rMet e 1 and challenged orally with a high dose of rMet e 1 to elicit an allergic response. These sensitized mice were then treated with a low (0.01 mg), medium (0.05 mg), or high dosage (0...

Antibiotics are known to cause severe cutaneous adverse reactions, such as the rare acute generalized exanthematous pustulosis (AGEP). Unlike Stevens-Johnson syndrome or toxic epidermal necrolysis, AGEP is rarely life-threatening. Systemic involvement is not typical, and if present usually coincides with a mild elevation of the hepatic enzymes and a decrease in renal function. Hence, AGEP is known to have a good prognosis and to be life-threatening only in elderly patients or patients with chronic diseases...

BACKGROUND: Hereditary angioedema (HAE) related to C1-inhibitor deficiency is a rare autosomal dominant disorder. Vascular cell adhesion molecules (VCAM) are known as endothelial activation markers. Endocan (also called ESM-1) is proposed as an endothelial dysfunction indicator. We aimed to investigate endothelial activation in attack-free periods in HAE patients by measuring their levels of endocan and VCAM-1. METHODS: Twenty-six HAE patients (22 female, mean age 40 ± 13 years) and 38 healthy control patients (13 female, mean age 36...

BACKGROUND: Saline nasal irrigation is labelled as an add-on treatment in patients with allergic rhinitis (AR). The primary aim of this study was to compare the efficacy of 21-day use of buffered hypertonic saline (BHS) versus normal saline solution (NSS) on reducing nasal symptoms in children with seasonal AR (SAR). Comparing their efficacy on nasal cytology counts (NCC), quality of life, and sleep quality was the secondary aim. METHODS: In this 21-day, open-label, randomized controlled study, 36 SAR children (aged 6-13 years) with a Total 5 Symptom Score (T5SS) ≥5 received twice-daily BHS or NSS delivered through a nasal douche...

Allergy is defined as an inappropriate immune response to something normally considered harmless. The symptomatic immune response is driven by IgE antibodies directed against allergens. The study of allergens has contributed significantly to our understanding of allergic disease in 3 main areas. First, identifying allergens as the cause of symptoms and developing allergen standards has led to many advances in exposure assessment and patient diagnostics. Second, a biochemical understanding of allergens has suggested a number of hypotheses related to the mechanisms of allergic sensitization...

BACKGROUND: Sublingual immunotherapy (SLIT) has been successfully employed in IgE-mediated respiratory allergies. However, it is not known whether the modulation of immune responses in the sublingual area during SLIT has any deleterious effect on oral health. We sought to determine the oral health prospectively in children receiving SLIT for house dust mite allergy. MATERIAL AND METHODS: Eighteen children with allergic asthma and/or rhinitis and 31 age-matched healthy controls (HC) were included in an open-labeled trial...
