Abstract
BACKGROUND Two common clinical syndromes of acetylsalicylic acid (aspirin) hypersensitivity, aspirin-exacerbated respiratory disease (AERD) and aspirin-exacerbated cutaneous disease (AECD), were subjected to a genome-wide association study to identify strong genetic markers for aspirin hypersensitivity in a Korean population. METHODS A comparison of SNP genotype frequencies on an Affymetrix Genome-Wide Human SNP array of 179 AERD patients and 1989 healthy normal control subjects (NC) revealed SNPs on chromosome 6 that were associated with AERD, but not AECD. To validate the association, we enrolled a second cohort comprising AERD (n = 264), NC (n = 238) and disease-control (aspirin tolerant asthma; ATA, n = 387) groups. RESULTS The minor genotype frequency (AG or AA) of a particular SNP, rs3128965, in the HLA-DPB1 region was higher in the AERD group compared to the ATA or NC group (P = 0.001, P = 0.002, in a co-dominant analysis model, respectively). Comparison of rs3128965 alleles with the clinical features of asthmatics revealed that patients harboring the A allele had increased bronchial hyperresponsiveness to inhaled aspirin and methacholine, and higher 15-HETE levels, than those without the A allele (P = 0.039, 0.037, and 0.004, respectively). CONCLUSIONS This implies the potential of rs3128965 as a genetic marker for diagnosis and prediction of the AERD phenotype.

Abstract
BACKGROUND/AIMS Chronic urticaria (CU) is defined as itchy wheals lasting 6 weeks or more. As the aged population increases worldwide, it is essential to identify the specific features of this disease in the elderly population. METHODS We investigated the prevalence and clinical features of CU in elderly patients. Medical records of 837 CU patients from the outpatient Allergy Clinic of Ajou University Hospital, Korea were analyzed retrospectively. Patients with chronic spontaneous urticaria according to the EAACI/GA2LEN/EDF/WAO guidelines were included. Patients older than 60 years were defined as elderly. RESULTS Of the 837 patients, 37 (4.5%) were elderly. In elderly versus nonelderly CU patients, the prevalence of atopic dermatitis (AD) was significantly higher (37.8% vs. 21.7%, respectively; p = 0.022), while that of aspirin intolerance was lower (18.9% vs. 43.6%, respectively; p = 0.003) in terms of comorbid conditions. The prevalences of serum specific immunoglobulin E antibodies to staphylococcal enterotoxin A and staphylococcal enterotoxin B were considerably higher in elderly CU patients with AD than in those without AD (37.5% vs. 0%, respectively). CONCLUSIONS Elderly patients with CU had a higher prevalence of AD. Therefore, there is a need to recognize the existence of AD in elderly CU patients.

Abstract
PURPOSE Cefaclor is widely prescribed for various infectious diseases. As its consumption increases, the number of hypersensitivity reactions to cefaclor has increased. This study aimed to evaluate the immunologic findings of immediate hypersensitivity to cefaclor. MATERIALS AND METHODS We enrolled 47 patients with immediate hypersensitivity to cefaclor from Ajou University Hospital and Asan Medical Center. Serum specific IgE, IgG1, and IgG4 antibodies to cefaclor-human serum albumin (HSA) conjugate were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS The most common phenotype was anaphylaxis (Group I, 78.7%), followed by urticaria (Group II, 21.3%). The detection of specific IgE, IgG1, and IgG4 to cefaclor-HSA conjugate by ELISA tended to be higher in Group I (40.5%, 41.7%, 21.6%) than in Group II (20.0%, 20.0%, 0%) with no statistical significance. Significant associations were found between specific IgE and IgG1 or IgG4 (p<0.001, p=0.019). ELISA inhibition tests showed significant inhibitions by both free cefaclor and cefaclor-HSA conjugate. For basophil activation tests in patients having no specific IgE antibody, the CD63 expression level on basophils increased with incubations of free cefaclor. CONCLUSION The most common manifestation of immediate hypersensitivity to cefaclor was anaphylaxis, most of which was mediated by IgE; however, a non-IgE mediated direct basophil activation mechanism was suggested in a subset of anaphylaxis patients.

Abstract
Purpose Differences in definitions of the condition, relevant triggers, and the geographical locations of study centers, cause estimates of the prevalence of anaphylaxis to vary. Recent epidemiological data indicate that the incidence of anaphylaxis is rising. Methods To investigate the causes and clinical features of anaphylaxis in Korean adults, factors associated with the severity of the condition, and serious outcomes, a retrospective medical record review was performed on adult patients diagnosed with anaphylaxis between 2007 and 2011 in 15 University Hospitals of South Korea. Results A total of 1,806 cases (52% male, age 16-86 years) were reported. Cutaneous symptoms (84.0%), combined with respiratory (53.9%) and/or cardiovascular (55.4%) symptoms, were the most frequent presentations. Using a recognized grading system, 1,776 cases could be classified as either mild, 340; moderate, 690; or severe, 746. Although eliciting factors varied significantly by age, gender, and regional and seasonal factors, drugs (46.5%; including nonsteroidal anti-inflammatory drugs, antibiotics, and radiocontrast media) were the most common cause of anaphylaxis, followed by foods (24.2%), insect stings (16.4%), exercise (5.9%), and unknown etiology (7.0%). All of age, multi-organ involvement, a history of allergic disease, and drug-induced anaphylaxis, were significant predictors of serious outcomes requiring hospital admission or prolongation of hospital stay. Epinephrine auto-injectors were prescribed for 7.4% of reported cases. Conclusions The principal causes of anaphylaxis in Korean adults were drugs, food, and insect stings. Drug-associated anaphylaxis, a history of allergic disease, multi-organ involvement, and older age, were identified as predictors of serious outcomes.

Abstract
BACKGROUND AND OBJECTIVE Airway hyperresponsiveness is a common feature of asthma. Methacholine and mannitol are two representative agonists for bronchial challenge. They have theoretically different mechanisms of action, and may have different diagnostic properties. However, their difference has not been directly evaluated among Korean adults. In this study, we compare the diagnostic properties of methacholine and mannitol bronchial provocation tests. METHODS Asthmatic patients and non-asthmatic controls were recruited prospectively from four referral hospitals in Korea. Participants were challenged with each of methacholine and mannitol inhalation on different days. Their diagnostic utility was evaluated by calculating their sensitivity and specificity for asthma diagnosis. Response-dose ratio was also compared. RESULTS A total of 50 asthmatic adults and 54 controls were enrolled (mean age 43.8 years). The sensitivity and specificity of mannitol challenge (defined by a PD15 of <635 mg) were 48.0% and 92.6%, respectively, whereas those of methacholine (defined by a PC20 of <16 mg/mL) were 42.0% and 98.1%, respectively. Twenty asthmatic participants (24%) showed positive response to a single agonist only. In the receiver operating curve analyses using response-dose ratio values, area under the curve was 0.77 (95% confidence interval (CI): 0.68-0.86) for mannitol, and 0.89 (95% CI: 0.83-0.95) for methacholine. The correlations between log- transformed mannitol and methacholine response-dose ratios were significant but moderate (r = 0.683, P < 0.001). CONCLUSIONS The present study demonstrated overall similar diagnostic properties of two diagnostic tests, but also suggested their intercomplementary roles for asthma. The clinical trial registration number at ClinicalTrial.gov is NCT02104284.

Abstract
Adverse reactions to antiepileptic drugs (AEDs) may lead to treatment failure, morbidity, and mortality. Drug hypersensitivity reactions (DHRs) are potentially fatal. AED DHRs present with a variety of clinical manifestations. The pathogenesis of AED DHRs has not been fully elucidated. Bioactivation, detoxification, covalent adduct formation, presentation to the immune system, and consequent formation of antibody and T-cell immune effectors have been suggested. This article summarizes the epidemiology, pathogenic mechanisms, risk factors, clinical features, and management of allergic reactions to the aromatic AEDs carbamazepine, phenytoin, and lamotrigine.

Abstract
BACKGROUND Chronic idiopathic urticaria (CIU) and atopic dermatitis (AD) are common allergic skin diseases associated with severe pruritus. AD skin is characterized by filaggrin deficiency, but it has not been studied in CIU. OBJECTIVE To compare the expression of filaggrin in skin from patients with CIU, patients with AD, and normal controls and to investigate whether altered filaggrin expression is associated with CIU severity. METHODS Skin biopsies were obtained from 16 patients with CIU, 11 patients with AD, and 14 normal controls. Filaggrin expression was evaluated using real-time reverse transcriptase polymerase chain reaction and immunostaining. Urticaria activity score, transepidermal water loss, and skin pH were measured. RESULTS FLG gene expression was significantly greater in lesional CIU skin compared with lesional AD skin (P < .01). The staining intensity of filaggrin was significantly increased in lesional CIU skin compared with skin from normal controls (P < .01) and lesional AD skin (P < .001). A significant correlation was observed between filaggrin staining intensity and urticaria activity score in patients with CIU (r = 0.538, P < .05). Transepidermal water loss was significantly increased in lesional skin of patients with AD compared with skin from normal controls (P < .01) and lesional skin from patients with CIU (P < .01). Skin pH was significantly decreased in lesional skin from patients with CIU compared with skin from normal controls (P < .01) and patients with AD (P < .001). CONCLUSION Filaggrin is overexpressed in lesional CIU skin, and increased filaggrin expression is positively correlated with urticaria severity in CIU. Altered filaggrin expression has physiologic effects on transepidermal water loss and pH in the skin of patients with CIU, suggesting increased barrier function compared with skin from patients with AD.

Abstract
Angioedema with eosinophilia (AE) is a very rare allergy disease, case reports of which have been published sporadically since 1984. Here, we retrospectively analyzed the clinical features of 10 AE patients in Korea. Nine of the 10 subjects were young females, ranging from 23 to 38 years old. Twenty percent of the subjects had episodic-type AE with high serum IgM and eosinophil counts, while 80% were non-episodic type with normal serum IgM levels but high eosinophil counts. All patients had used systemic corticosteroids to control AE. One patient with refractory episodic-type AE was treated with anti-IgE antibody. This is the first study to evaluate the clinical characteristics of AE in a Korean population.

Abstract
Staphylococcus aureus is the most common bacterium present in upper respiratory tract, and the toxins it produced are involved in allergic inflammation pathogenesis. In this study, we investigated the clinical significance of IgE in association with staphylococcal superantigens in allergic asthma with rhinitis (BAwAR) and allergic rhinitis alone (AR). We recruited 100 patients with BAwAR (group I), 100 patients with AR (group II), and 88 healthy controls (group III). Patients were clinically diagnosed by physicians, and were sensitized to house dust mites. Specific IgE antibodies to staphylococcal superantigen A (SEA), B (SEB), and toxic shock syndrome toxin-1 (TSST-1) were measured using the ImmunoCAP system. Other clinical parameters were retrospectively analyzed. All specific IgE antibodies to SEA, SEB, and TSST-1 were detected most frequently in group I (22%, 21%, and 27%), followed by group II (11%, 14%, and 21%) and group III (4.5%, 3.4%, and 2.3%). Absolute values of serum specific IgE to SEA, SEB, and TSST-1 were also significantly higher in group I (0.300±1.533 kU/L, 0.663±2.933 kU/L, and 0.581±1.931 kU/L) and group II (0.502±2.011 kU/L, 0.695±3.337 kU/L, and 1.067±4.688 kU/L) compared to those in group III (0.03±0.133 kU/L, 0.03±0.14 kU/L, and 0.028±0.112 kU/L). The prevalence of serum specific IgE to SEA was significantly higher in group I compared to group II (P=0.025). Blood eosinophil counts were significantly higher in patients with specific IgE to SEA or SEB, and higher serum levels of specific IgE to house dust mites were noted in patients with specific IgE to TSST-1. In conclusion, the present study suggested that IgE responses to staphylococcal superantigens are prevalent in the sera of both BAwAR and AR patients. This may contribute to an augmented IgE response to indoor allergens and eosinophilic inflammation.

Abstract
Increased FcεR1α expression with upregulated CD203c expression on peripheral basophils is seen in patients with chronic urticaria (CU). However, there has been no published report on the association between CD203c expression level and clinical disease activity in CU patients. To investigate whether the increase of basophil activation is associated with the disease activity of CU, we measured basophil CD203c expression using a tricolor flow cytometric method in 82 CU patients and 21 normal controls. The relationship between the percentage of CD203c-expressing basophils and clinical parameters was analyzed. The mean basophil CD203c expression was significantly higher in CU patients than in healthy controls (57.5% vs 11.6%, P < 0.001). The basophil CD203c expression in severe CU patients was significantly higher than in non-severe CU (66.5% ± 23.3% vs 54.0% ± 23.3%, P = 0.033). Multiple logistic regression analysis indicated that both ≥ 72% basophil CD203c expression and urticaria activity score (UAS)≥ 13 were significant predictors of severe CU (P = 0.005 and P = 0.032, respectively). These findings suggest that the quantification of basophil activation with CD203c at baseline may be used as a potential predictor of severe CU requiring another treatment option beyond antihistamines.

Abstract
Codeine is widely prescribed in clinical settings for the relief of pain and non-productive coughs. Common adverse drug reactions to codeine include constipation, euphoria, nausea, and drowsiness. However, there have been few reports of serious adverse reactions after codeine ingestion in adults. Here, we present a case of severe anaphylaxis after oral ingestion of a therapeutic dose of codeine. A 30-year-old Korean woman complained of the sudden onset of dyspnea, urticaria, chest tightness, and dizziness 10 minutes after taking a 10-mg dose of codeine to treat a chronic cough following a viral infection. She had previously experienced episodes of asthma exacerbation following upper respiratory infections, and had non-atopic rhinitis and a food allergy to seafood. A skin prick test showed a positive response to 1-10 mg/mL of codeine extract, with a mean wheal size of 3.5 mm, while negative results were obtained in 3 healthy adult controls. A basophil histamine release test showed a notable dose-dependent increase in histamine following serial incubations with codeine phosphate, while there were minimal changes in the healthy controls. Following a CYP2D6 genotype analysis, the patient was found to have the CYP2D6*1/*10 allele, indicating she was an intermediate metabolizer. An open label oral challenge test was positive. To the best of our knowledge, this is the first report of a patient presenting with severe anaphylaxis after the ingestion of a therapeutic dose of codeine, which may be mediated by the direct release of histamine by basophils following exposure to codeine.

Abstract
Atopic dermatitis (AD) is characterized by epidermal barrier defects and recurrent microbial skin infections. AD patients with a history of eczema herpeticum (ADEH+) have more severe skin disease and more highly T helper type 2 (Th2)-polarized immune responses as compared with uncomplicated AD (ADEH-). However, the mechanisms linking epidermal barrier defects and viral skin infection are not well understood. Recently, it has been reported that interleukin-25 may play a role in augmenting Th2 responses. We examined protein expression of IL-25 in the skin biopsies from normal subjects (n=10), ADEH- (n=18), ADEH+ (n=7), and psoriasis (n=9). IL-25 expression was increased in the skin from ADEH-, ADEH+, and psoriasis as compared with normal skin, and was significantly greater in lesional ADEH+ skin than in lesional ADEH- skin. Importantly, we demonstrated that IL-25 enhances herpes simplex virus (HSV)-1 and vaccinia virus replication by inhibiting filaggrin expression, and IL-25 acts synergistically with IL-4 and IL-13 to enhance HSV-1 replication in vitro. In contrast, IFN-γ inhibited HSV-1 replication in vitro. In addition, we demonstrate that filaggrin is a critical protein to inhibit HSV-1 replication because filaggrin small interfering RNA knockdown enhances HSV-1 replication in vitro. Filaggrin breakdown products, however, inhibited HSV-1 replication in vitro.

A computerized asthma-specific quality of life: a novel tool for reflecting asthma control and predicting exacerbation. Int Arch Allergy Immunol 2013; 163:36-42. [PMID: 24247849 DOI: 10.1159/000356336] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2013] [Accepted: 10/07/2013] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Proper assessment of health-related quality of life is essential to achieve and maintain a controlled status in asthmatic patients. We developed our own computerized asthma-specific quality-of-life (cA-QOL) questionnaire based on in-depth interviews with adult asthmatic patients. In this study, we evaluated this cA-QOL in terms of the Asthma Control Test (ACT) score and Global Initiative for Asthma (GINA) guidelines as well as asthma exacerbation, and compared it with the asthma-related quality-of-life questionnaire (AQLQ). METHODS We conducted a multicenter, prospective, observational study in 133 adult asthmatic patients recruited from 5 university hospitals in South Korea, who were randomized into 2 groups according to the operating order of the cA-QOL and AQLQ. At every visit (3-month interval), physicians evaluated asthma control status with monitoring spirometry. The self-administered cA-QOL, AQLQ(S) and ACT were completed. RESULTS The cA-QOL scores correlated significantly with ACT and AQLQ(S) scores (r = 0.814, p < 0.001; r = 0.900, p < 0.001). The cA-QOL score was significantly lower where the ACT score was <19, in the patients with an uncontrolled asthma status according to the GINA guidelines and in those with asthma exacerbation (p < 0.001, respectively). A multivariate analysis showed that this cA-QOL was a significant parameter associated with an uncontrolled asthma status and asthma exacerbation (p < 0.001, p = 0.045, p = 0.019, respectively). CONCLUSION The cA-QOL is a valid tool for reflecting current asthma control status and for assessment to predict the future risk of asthma exacerbation in adult asthmatics.

Abstract
Specific IgE to gliadin was proposed as a marker for wheat dependent exercise induced anaphylaxis, while Tri a 14 was found to induce IgE response in baker's asthma. We evaluated whether these components could be used for discriminating phenotypes of wheat allergy. Twenty-nine patients who were wheat-induced anaphylaxis and/or urticaria (n=21, group I) and baker's asthma (n=8, group II) were enrolled. The prevalence of serum specific IgE to Tri a 14 was higher in group II (25%) than in group I (4.8%), while the serum specific IgE to gliadin was significantly higher in group I (70%) than in group II (12.5%). The cutoff value for predicting the baker's asthma using the ratio of serum specific IgE to Tri a 14 to gliadin was 742.8 optical density×1,000/(kU/L) with high sensitivity and specificity. These findings suggest that Tri a 14/gliadin may be a potential marker for predicting baker's asthma.

Abstract
Polyvinyl chloride (PVC) is a widely used chemical for production of plastics. However occupational asthma (OA) caused by PVC has been reported only rarely. We report a 34-yr-old male wallpaper factory worker with OA due to PVC and nickel (Ni) whose job was mixing PVC with plasticizers. He visited the emergency room due to an asthma attack with moderate airflow obstruction and markedly increased sputum eosinophil numbers. A methacholine challenge test was positive (PC20 2.5 mg/mL). Bronchoprovocation tests with both PVC and Ni showed early and late asthmatic responses, respectively. Moreover, the fractional concentration of exhaled nitric oxide (FeNO) was increased after challenge with PVC. To our knowledge, this is the first case of OA in Korea induced by exposure to both PVC and Ni. We suggest that eosinophilic inflammation may be involved in the pathogenesis of PVC-induced OA and that FeNO monitoring can be used for its diagnosis.

ALLERGY, ASTHMA & IMMUNOLOGY RESEARCH 2013; 5:309-14. [PMID: 24003388 PMCID: PMC3756178 DOI: 10.4168/aair.2013.5.5.309] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/12/2012] [Revised: 12/26/2012] [Accepted: 01/16/2013] [Indexed: 11/20/2022]
Abstract
PURPOSE The sensitization rate to Japanese Hop (Hop J) in respiratory allergy patients has increased in recent years in Korea. We evaluated changes in the allergenic potency of Hop J pollen collected in 1998 and 2009. METHODS Thirty-five patients with allergic rhinitis and/or asthma were enrolled. Group I included 21 subjects sensitized to Hop J at an initial visit and group II included 14 subjects who developed a new sensitization. Hop J pollens were collected in 1998 and 2009 (98 and 09 extracts) and both urban and suburban environments (urban and suburban extracts). Serum specific IgE levels to Hop J pollen extracts were compared using an enzyme-linked immunosorbent assay (ELISA). IgE binding components were compared by IgE immunoblot analysis. RESULTS Serum specific IgE levels to the 09 and urban extracts in both groups increased significantly compared to those of the 98 and suburban extracts. IgE immunoblot demonstrated that the major 10 kDa allergen was intensified in group I, while it was newly generated in group II with additional components ranging from 12-95 kDa. When the 98 and 09 extracts were compared, intensification of the major allergen of 09 extract had occurred in both groups. The IgE binding components of the urban extract was stronger than those of suburban one. CONCLUSIONS The allergenic potency of Hop J pollen may be increased with environmental changes.
