Peanut allergy as a trigger for the deterioration of atopic dermatitis and precursor of staphylococcal and herpetic associated infections: Case report

摘要

Atopic dermatitis (AD) is a multifactorial and chronic disease, with genetic, environmental, immunological and nutritional origins. AD may be aggravated by allergies associated with infections. This study aims to describe a paediatric case of AD in which the peanut allergy was the triggering factor to aggravate the disease, and was also the concomitant precursor of staphylococcal (methicillin-sensitive Staphylococcus aureus, carrier of the Panton-Valentine leukocidine (PVL) genes) and herpetic (Herpes Simplex - HSV) infections. The clinical management approach and nursing strategies promoted a favourable evolution during the hospitalization period, besides the family approach, which was essential to control any flare-up of the disease. Adherence to a recommended diet and the use of strategies to prevent any recurrent infections were important to ensure the patient's quality of life.
