Pharyngitis caused by the group A streptococcus requires accurate diagnosis and timely treatment to prevent acute rheumatic fever. Clinical signs and symptoms often do not distinguish pharyngitis caused by group A streptococci from pharyngitis caused by other microorganisms. Rapid antigen detection or throat culture are recommended for diagnosis except when viral signs and symptoms are prominent. Therapy with penicillin, the drug of choice, is associated with prevention of rheumatic fever, more rapid clinical improvement, and prompt loss of contagiousness. Bacteriologic treatment failure occurs despite universal sensitivity of group A streptococci to penicillin. The cause of treatment failure (and of chronic carriage) remain to be determined. Newer, more expensive antibiotics do not substantially enhance treatment success and need not be prescribed for most patients.
A组链球菌引起的咽炎需要准确诊断并及时治疗,以预防急性风湿热。临床体征和症状往往无法区分A组链球菌引起的咽炎与其他微生物引起的咽炎。除了病毒体征和症状突出时,推荐采用快速抗原检测或咽拭子培养进行诊断。首选药物青霉素治疗可预防风湿热,使临床症状更快改善,并迅速消除传染性。尽管A组链球菌对青霉素普遍敏感,但仍会出现细菌学治疗失败的情况。治疗失败(以及慢性带菌)的原因尚待确定。更新、更昂贵的抗生素并不能显著提高治疗成功率,大多数患者无需使用。
