001); no large differences were observed among allergens. Among the subjects who failed LD-OFCs, the median change in the total dose in the LD-OFC was 235% (interquartile range 100%-512%) in the SLOIT group and 100% (42%-235%) in the control group (P less then .001). Provoked allergic symptoms were observed in only 0.58% (280/48,486) per programmed intake and approximately 50% of the SLOIT group did not experience any obvious allergic symptoms throughout therapy. Conclusions SLOIT showed significant feasibility, efficacy and safety, providing a promising option to manage patients with severe food allergies.Background An orosomucoid-like 3 (ORMDL3)/gasdermin B (GSDMB) gene locus on chromosome 17q is consistently associated with childhood-onset asthma, which is highly atopic. As some evidence suggests the relationship between asthma and allergic sensitization reflects asthma patient susceptibility to augmented IgE responses driven by common environmental allergens rather than an increased asthma risk after allergen exposure, we aimed to determine any relationships between this locus region and childhood-onset adult asthma with regard to serum total IgE levels or allergic sensitization. Methods We conducted a case-control association study using three independent Japanese populations (3869 total adults) and analyzed the ORs for association of rs7216389, an expression quantitative trait locus for ORMDL3/GSDMB, with adult asthma according to onset age. Additionally, associations between the rs7216389 genotype and total serum IgE levels or allergic sensitization was examined. Results Rs7216389 was associated with both childhood-onset adult asthma (OR for asthmatic patients afflicted at the age of 10 years or younger = 1.61, p = 0.00021) and asthmatic patients with higher levels of total serum IgE (OR for asthmatic patients with IgE ≥1000IU/mL = 1.55, p = 0.0033). In both healthy controls and in the combined healthy and asthmatic individuals, rs7216389 was correlated with increased total serum IgE levels (p 0.1). Conclusions ORMDL3/GSDMB is an important susceptibility gene for childhood-onset adult asthma in Japanese populations and this association is linked to elevated total serum IgE levels but not to allergic sensitization.Background Pollen food Syndrome (PFS) to Rosaceae fruits and soybean, related to Bet v 1 homologue sensitization has been reported increasingly throughout Japan, possibly due to the wide distribution of alder. Methods In 2015, we conducted a school-based questionnaire survey among two age groups; students in primary school (Years 1-2) and secondary school (Years 8-9) from each of the 47 prefectures of Japan. We analyzed the prevalence, demographic and clinical characteristics of children with oral symptoms to Rosaceae fruits/soybean; defined as oral symptoms occurring shortly after ingesting apple, peach, cherry or soybean. Additionally, we assessed the correlation between the prevalence and external data on alder sensitization rates by prefecture. Results Responses from 41,264 primary and 35,302 secondary school students were analyzed. The prevalence of oral symptoms to Rosaceae fruits/soybean was 0.99%, 95%CI 0.89-1.09% and 2.75%, 95%CI 2.59-2.93% among each age group, respectively. Children with oral symptoms were more likely to have parental and personal history of allergic disease compared to those without symptoms. Oral symptoms were experienced more often in children with severe spring allergic rhinitis or have both allergic rhinitis and wheeze. There was a strong correlation between the prevalence of oral symptoms and alder sensitization rates by prefecture among both age groups (r = 0.63, p less then 0.001 and r = 0.76, p less then 0.001, respectively). Conclusions Oral symptoms to Rosaceae fruits/soybean, which is suggestive of PFS was reported by 1-3% Japanese school children. It was associated with the geographic alder sensitization rate, supporting the underlying sensitization to Bet v 1.Background In the LIBERTY ASTHMA QUEST (ClinicalTrials.gov NCT02414854) study, dupilumab 200 mg and 300 mg every 2 weeks vs matched-volume placebo reduced severe asthma exacerbations and improved lung function (FEV1), asthma control, and quality of life in patients with uncontrolled, moderate-to-severe asthma (N = 1902). Here, we examine the safety and efficacy of dupilumab in the subpopulation of Japanese patients who participated in QUEST (n = 114; 6%). RO4929097 Methods Endpoints assessed were annualized severe exacerbation rates and the effect of treatment over the 52-week treatment period on FEV1, asthma control, asthma-related quality of life, and markers of type 2 inflammation. Results In Japanese patients, dupilumab 200 and 300 mg every 2 weeks vs matched placebo reduced severe asthma exacerbation rates by 44% (P = 0.33) and 75% (P = 0.03), respectively, and improved FEV1 at Week 12 by 0.20 L (P = 0.05) and 0.17 L (P = 0.12). FEV1 improvements were rapid (by Week 2) and sustained throughout treatment. Significant and/or numerical improvements vs placebo in asthma control and quality of life were also observed throughout treatment. For each endpoint, greater efficacy was observed in patients with elevated baseline levels of type 2 inflammatory biomarkers (blood eosinophils or FeNO). Dupilumab treatment significantly reduced levels of FeNO and total IgE, but not blood eosinophils. Conclusions In this subanalysis of QUEST, the efficacy and safety of dupilumab in Japanese patients was comparable to that observed in the overall intention-to-treat population, suggesting no variability in efficacy on the basis of Japanese ethnicity.

However, few investigations shed light on useful biomarkers for predicting the decline of pulmonary function. We evaluated whether thymus and activation-regulated chemokine (TARC), a Th2 inflammation marker, could predict rapid FEV1-decline in COPD patients. Methods We recruited 161 patients with stable COPD and performed pulmonary function test once every six months. At the time of registration, blood tests, including serum levels of TARC were performed. We assessed the correlation between changes in parameters of pulmonary function tests and serum levels of TARC. The rapid-decline in pulmonary function was determined using 25th percentile of change in FEV1 or FEV1 percent predicted (%FEV1) per year. Results In the FEV1-rapid-decline group, the frequency of exacerbations, the degree of emphysema, and serum levels of TARC was higher than in the non-rapid-decline group.
