 A butterfly flaps its wings: Extinction of biological experience and the origins of allergy


Authors: Susan L.PrescottMD, PhD, FRACP∗†


Abstract

Objective

To explore links between biodiversity on all scales and allergic disease as a measure of immune dysregulation.


Data Sources

PubMed and Web of Science were searched using the keywords biodiversity, nature relatedness, allergic disease, microbiome, noncommunicable diseases, coronavirus disease 2019, and associated terms.


Study Selections

Studies were selected based on relevance to human health and biodiversity.


Results

Contact with natural environments enriches the human microbiome, promotes regulated immune responses, and protects against allergy and both acute and chronic inflammatory disorders. These important links to ecopsychological constructs of the extinction of experience, which indicates that loss of direct, personal contact with biodiversity (wildlife and the more visible elements of the natural world), might lead to emotional apathy and irresponsible behaviors toward the environment.


Conclusion

The immune system is a useful early barometer of environmental effects and, by means of the microbiome, is a measure of the way in which our current experiences differ from our ancestral past. Although we would benefit from further research, efforts to increase direct, personal contact with biodiversity have clear benefits for multiple aspects of physical and mental health, the skin and gut microbiome, immune function, food choices, sleep, and physical activity and promote environmental responsibility.

La biopsia cutánea en la urticaria crónica: cuándo realizarla, qué buscar y dónde hacerlo

La biopsia cutánea en la urticaria crónica: cuándo realizarla, qué buscar y dónde hacerlo Autores: A. López Mateos, M.J. Sánchez Pujol y J.F. Silvestre Salvador Resumen: La urticaria crónica es una entidad relativamente frecuente en la práctica clínica habitual, cuyo diagnóstico se establece de forma clínica. Sin embargo, existen ocasiones en las que está indicada la realización de una biopsia cutánea para confirmar el diagnóstico y diferenciarla de otras patologías que pueden cursar con erupciones urticariformes. En este trabajo revisamos los hallazgos histopatológicos que podemos encontrar tanto en la urticaria crónica como en las patologías que plantean un diagnóstico diferencial. Con base en ello, proponemos un algoritmo que recoge las indicaciones para realizar una biopsia cutánea y la orientación del diagnóstico en función de los hallazgos histopatológicos que encontremos en la misma.

Managing Food Allergy When the Patient Is Not Highly Allergic

Managing Food Allergy When the Patient Is Not Highly Allergic Authors: Scott H. Sicherer, MD, Elissa M. Abrams, MD, Anna Nowak-Wegrzyn, MD, PhD, and Jonathan O’B. Hourihane, FRCPI Abstract: Few patients with food allergy are “highly allergic,” meaning they always have severe reactions and always react to very small amounts of allergen. Standard medical approaches for allergy management have focused on the safety and lifestyle modifications this group truly needs, but consequently families with food allergy are typically advised to strictly avoid any exposure to their implicated allergens. Most food-allergic subjects are actually not reactive to very low doses, and many never experience severe reactions. There are also notable conditions where a different care plan is already commonly offered: patients with pollen-related food allergy syndrome, with food-associated exercise-induced anaphylaxis, and with resolving or mild milk or egg allergy might be advised to ingest the allergens in sp...
