Group A Streptococcal (GAS) pharyngitis is the most common bacterial infection which needs antibiotic treatment. GAS accounts for only 10-15% of adult acute pharyngitis cases. The overuse of antibiotics for viral pharyngotonsillitis is common and may lead to inappropriate antimicrobial stewardship and the emergence of bacterial resistance. However, the etiology of acute pharyngotonsillitis for hospitalized adult patients is rarely studied. So, we reported the 10-year surveillance data of hospitalized adult patients with acute pharyngotonsillitis in a regional hospital in Taiwan. Every consecutive adult patient admitted with acute pharyngotonsillitis in 2011-2021 was recruited for a complete etiology study. The etiology of acute pharyngotonsillitis was identified in 117 patients. Overall, 42 herpes simplex virus cases, 26 adenovirus cases, 16 acute human immunodeficiency virus cases, 12 influenza cases, three parainfluenza cases, six Epstein-Barr virus cases, one cytomegalovirus case, four enterovirus cases, one varicella-zoster virus case, four <i>Mycoplasma pneumoniae</i> cases, one <i>Chlamydophila pneumoniae</i> case, and only one GAS case were identified. The average of the points for the Modified Centor Criteria was 1.38 (55% of patients with 0-1 points and 45% with 2-3 points). However, 88.9%of patients received antibiotics at the emergency department, and 76.9%also received antibiotics while hospitalized. Only a few patients required antibiotic treatment, while the majority of patients with viral illness needed only symptomatic treatment. However, distinguishing viral etiology from GAS pharyngitis is challenging even in the presence of tonsil exudates, high C-reactive protein, and leukocytosis. A diagnostic algorithm and the application of the Modified Centor Criteria should be considered for hospitalized adults with acute pharyngotonsillitis to improve antimicrobial stewardship.</p>","PeriodicalId":18667,"journal":{"name":"Microorganisms","volume":"13 3","pages":""},"PeriodicalIF":4.1,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11944335/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143720268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
