J Dermatol 2021 Sep 14. Epub 2021 Sep 14.

Proteomic and Flow Cytometry Unit, Bnai-Zion Medical Center, Rappaport Faculty of Medicine, Technion, Haifa, Israel.

When chronic spontaneous urticaria (CSU) is resolved, patients are often apprehensive about the likelihood of recurrence, and want to know if we can predict this using clinical or laboratory markers. This question is crucial because CSU is frequently accompanied by a high incidence of stressful comorbidities, and the fear of experiencing this again can be devastating to the patient. This study was designed with the aim of focusing on the prevalence and characteristics of the recurrence of CSU. Read More

Allergy 2021 Sep 14. Epub 2021 Sep 14.

Swiss Institute of Allergy and Asthma Research (SIAF), University of Zurich, Davos, Switzerland.

During the past years, there has been a global outbreak of allergic diseases, presenting a considerable medical and socioeconomical burden. A large fraction of allergic diseases is characterized by a type 2 immune response involving Th2 cells, type 2 innate lymphoid cells, eosinophils, mast cells, and M2 macrophages. Biomarkers are valuable parameters for precision medicine as they provide information on the disease endotypes, clusters, precision diagnoses, identification of therapeutic targets, and monitoring of treatment efficacies.
