The Gut Microbiome of Adults with Allergic Rhinitis Is Characterised by Reduced Diversity and an Altered Abundance of Key Microbial Taxa Compared to Controls
Conclusion: Adult AR sufferers have a distinct gut microbiome profile, marked by a reduced microbial diversity and altered abundance of certain microbes compared to controls. The results of this study provide evidence that unique gut microbial patterns occur in AR sufferers in adulthood and warrant further examination in the form of mechanistic studies.Int Arch Allergy Immunol
CONCLUSIONS: Increased TRPV4 expression occurred in epithelial cells harvested from patients with AR and epithelial cells stimulated by Th2 cytokines. Decreased junctional protein expression in epithelial cells after the stimulation by house dust mite allergen with TRPV4 agonist indicates a possible role of TRPV4 in the pathogenesis of allergen-induced epithelial barrier disruption in AR.

Biologics have revolutionized medical therapy in the past 2 decades. Allergic Diseases have benefited from this revolution as a variety of biologics have impacted all categories of allergic diseases. Anticytokines directed at type 2 immunity has helped in the treatment of all allergic conditions covered in this issue ranging from Allergic Rhinitis to Asthma to Atopic Dermatitis to Food Allergy and others. Obviously, the ravages of COVID-19 on processes involved in biologic treatment are a consideration, but current thinking suggests such therapies should not be affected by the pandemic.
Conclusions: Our findings do not confirm the hypothesis of a positive association between pollen exposure and the prevalence of allergic rhinitis and asthma. PMID: 32994777 [PubMed]
CONCLUSION: Atopic disorders, previously recognized as predictors of poor sleep, are associated with COPCs after accounting for sleep problems. PMID: 32975542 [PubMed - as supplied by publisher]
Conclusions: sCD48 may be a biomarker to the exacerbation phase in patients with IAR. One can assume that CD48 participates in the pathogenesis of IAR.Int Arch Allergy Immunol
Conclusion: A hypertonic EO-based nasal spray could be a new and natural option in the management of PAR. It could also be used as an add-on therapy when nasal symptoms are not fully controlled.Int Arch Allergy Immunol
This study has the potential to transform the diagnosis and treatment of allergic disorders.
Abstract Pollen from trees, grasses, and weeds can trigger asthma exacerbation in sensitized individuals. However, there are gaps in knowledge about the effects, such as the relative risks from different plant taxa and threshold levels of effect. We aimed to describe the local association between pollen and asthma exacerbation among children in the City of Philadelphia, and to evaluate whether effects are modified by children's characteristics and clinical factors (e.g., child's age, race/ethnicity, comorbidities). We conducted a time-stratified case-crossover study of pediatric (age
Conclusion: Angioedema was the most typical symptom, and propionic acid derivatives were the most frequently reported culprit drugs. The significant risk factors predicting NSAID hypersensitivity were personal history of AR/CRS, onset of NSAID hypersensitivity reaction over 15 years old, and immediate reaction.Int Arch Allergy Immunol
