Abstract
Introduction
Reactions to β-lactam antibiotics account for up to 80% of pediatric consultations for suspected drug allergy. This study aimed to describe the characteristics of children evaluated in the emergency department for suspected allergy to amoxicillin or amoxicillin-clavulanate.
Materials and methods
We conducted a descriptive, retrospective study in a tertiary hospital (January 2019-May 2024), including patients ≤16 years with a diagnosis of suspected allergy to these antibiotics.
Results
Eighty-two cases were analyzed; 93.9% presented with cutaneous lesions and none showed hemodynamic instability. Two patients received intramuscular epinephrine for immediate reactions consistent with mild anaphylaxis. Antibiotic treatment was discontinued in 95.1% of cases, and 54.7% of the substitutions were considered inappropriate. A total of 69.5% were referred to Allergy, and only 7 patients (12.3%) were confirmed to have true amoxicillin allergy.
Conclusions
Suspected amoxicillin allergy in pediatric emergency care generally has a favorable prognosis. The low diagnostic confirmation rate and frequent inappropriate antibiotic changes highlight the need to improve adherence to clinical guidelines.
期刊介绍:
Hoy está universalmente reconocida la renovada y creciente importancia de la patología infecciosa: aparición de nuevos agentes patógenos, de cepas resistentes, de procesos con expresión clínica hasta ahora desconocida, de cuadros de una gran complejidad. Paralelamente, la Microbiología y la Infectología Clínicas han experimentado un gran desarrollo como respuesta al reto planteado por la actual patología infecciosa. Enfermedades Infecciosas y Microbiología Clínica es la Publicación Oficial de la Sociedad Española SEIMC. Cumple con la garantía científica de esta Sociedad, la doble función de difundir trabajos de investigación, tanto clínicos como microbiológicos, referidos a la patología infecciosa, y contribuye a la formación continuada de los interesados en aquella patología mediante artículos orientados a ese fin y elaborados por autores de la mayor calificación invitados por la revista.
