The aim of this study was to pilot a simpler and more effective method for identifying dust mites in sputum. Dust mites and their allergens have been implicated in respiratory diseases, including pulmonary acariasis, and several studies have identified mites in sputum. Further research is dependent on the development of a faster and simpler diagnostic test. We have demonstrated that dust mites artificially introduced into sputa, could be identified after the sputa were liquefied with bleach, when the liquid sample was observed under the microscope. Liquefaction times for serous, mucous, purulent and hemoptoic sputa varied from 10 to 30 min (mean 17.5). The test had a sensitivity of 80% (95% CI 68.2-88.2%) as 46/60 mites were identified. This procedure can be performed quickly at room temperature, is simple, inexpensive, repeatable, and less labourious than previous methods.

Background: Alzheimer's disease (AD) is an age-related neurodegenerative disorder affecting nearly 50 million individuals worldwide. Besides aging, various comorbidities can increase the risk of AD, such as asthma. However, the molecular mechanism(s) underlying this asthma-associated AD exacerbation is unknown.

Asthma affects approximately 300 million individuals worldwide and the onset predominantly arises in childhood. Children are exposed to multiple environmental irritants, such as viruses and allergens, that are common triggers for asthma onset, whilst their immune systems are developing in early life. Understanding the impact of allergen exposures on the developing immune system and resulting alterations in lung function in early life will help prevent the onset and progression of allergic asthma in children.

Standardized quality (SQ) house-dust mite (HDM) sublingual immunotherapy tablets (10,000 Japanese allergy units [JAU], equivalent to 6 SQ-HDM in Europe and the United States) are licensed for the treatment of HDM-induced allergic rhinitis (AR) without age restriction, based on 52-week administration clinical trials. There are no large-scale data on the administration of 10,000 JAU for > 1 year in actual clinical practice. To examine the safety and effectiveness of 10,000 JAU during use for up to 3 years at real-world clinical sites in Japan.

This study aimed to investigate the relationship between allergen-specific immunoglobulin E (IgE) sensitization and allergic rhinitis (AR) symptoms in school-aged children in Japan and to understand the current severity of AR symptoms and the quality of life (QOL) among children with AR. We analyzed data from 8-year-old children who participated in the Yamanashi Adjunct Study of the Japan Environment and Children's Study, focusing on those with complete information on specific IgE levels and AR (1229 for perennial AR [PAR] and 1196 for seasonal AR [SAR]). Sensitization was determined when allergen-specific IgE levels were class 2 (0.
