Abstract
Objective
This study aimed to assess the cause of acute pharyngitis and determine the duration of severe and moderate symptoms based on the aetiology.
Design
Prospective observational study.
Site
One urban health care centre.
Participants
Patients aged 15 or older with acute pharyngitis were included.
Interventions
Bacterial identification was carried out in the microbiology lab using MALDI-TOF in two throat samples. Patients received a symptom diary to return after one week.
Main measurements
Number of days with severe symptoms, scoring 5 or more in any of the symptoms included in the symptom diary, and moderate symptoms, scoring 3 or more.
Results
Among the 149 patients recruited, beta-haemolytic streptococcus group A (GABHS) was the most common aetiology. Symptoms and signs alone as well as the mean Centor score cannot distinguish between GABHS and other bacterial causes in patients with acute pharyngitis. However, there was a trend indicating that infections caused by Streptococcus dysgalactiae and Streptococcus agalactiae presented more severe symptoms, whereas infections attributed to the Streptococcus anginosus group, Fusobacterium spp., and those where oropharyngeal microbiota was isolated tended to have milder symptoms. S. dysgalactiae infections showed a trend towards longer severe and moderate symptom duration.
Conclusion
GABHS was the most prevalent, but group C streptococcus caused more severe and prolonged symptoms.
期刊介绍:
Atención Primaria es una revista que publica trabajos de investigación relativos al ámbito de la atención primaria de salud. Desde el punto de vista conceptual, Atención Primaria asume el nuevo modelo de atención primaria de salud, orientado no sólo a la curación de la enfermedad, sino también a su prevención y a la promoción de la salud, tanto en el plano individual como en el de la familia y la comunidad. En estos nuevos aspectos que definen el modelo de atención primaria de salud es en los que se centran los trabajos de investigación que publica Atención Primaria, la primera revista de originales española creada para recoger y difundir la producción científica realizada desde los centros de atención primaria de salud sobre cuestiones como protocolización de la asistencia, programas de prevención, seguimiento y control de pacientes crónicos, organización y gestión de la asistencia primaria, entre otros.
