Combined Integrative RNA-Seq and Serological sIgE Analysis Enhances Understanding of Fish Allergen Profiles and Diagnostic Strategy for Fish Allergy.

Fish allergy is a significant health concern, with diagnosis and management complicated by diverse fish species and allergens. We conducted a comprehensive RNA-seq analysis of eight fish species to identify allergen profiles, integrating ImmunoCAP sIgE data to explore associations with allergen expression and diagnostic performance. Over 30 putative fish allergens were identified, with varying sequence similarities and expression levels, roughly classifying fish into two groups based on parvalbumin (PV) expression.

Changing pattern of pediatric anaphylaxis in Hong Kong, 2010-2019.

Background: Anaphylaxis is a significant health burden in most Western countries, but there are little published data on the incidence and pattern of anaphylaxis in Asia. We aim to determine the incidence rate and pattern of anaphylaxis over the past decade among the pediatric population in Hong Kong.

Methods: Medical records of patients presenting with allergy-related symptoms during the period 2010 to 2019 were examined.

Myocardial oedema in an 8-year-old Chinese boy with Idiopathic systemic capillary leak syndrome.

Background: Idiopathic systemic capillary leak syndrome (ISCLS) is rare, and there has been about 32 cases reported in children worldwide since this disorder was first described in 1960. Clinical guidelines on the management approach stemming from robust scientific evidence are lacking. This case report presents the first reported paediatric case of severe ISCLS with significant myocardial oedema and emphasizes this disease's impact on a child's cardiac function.
