A组乙型溶血性链球菌感染90例临床分析

目的 分析总结A组乙型溶血性链球菌(group A Streptococcus pyogens, GAS)感染患者的临床特点以提高诊疗水平。方法 收集温州医科大学附属第二医院自2005-2016年收住的90例证实为GAS感染患者的临床资料并进行统计分析。结果 GAS感染在儿童中最常见的疾病表现为扁桃体炎(38.0%)，成人中则为局部皮肤软组织感染(72.7%)。实验室指标，C反应蛋白(CRP)、白细胞(WBC)、降钙素原(PCT)、抗链球菌溶血素O(ASO)可有所升高。目前GAS对常用抗菌药物仍较敏感。预后89例治愈后出院，1例死亡病例。结论 GAS感染在儿童中以学龄期常见，在成人中以中年期常见。GAS感染患者在合理使用抗菌药物后，预后良好，少有危重症感染发生。

Analysis of 90 cases' clinical manifestation of group A Streptococcus pyogens infections

Objective To analyse the clinical features in patients with Group A Streptococcal infection. Methods We collected the clinical data of 90 patients diagnosed with GAS infections isolates from 2005 to 2016 in The Second Affiliated Hospital of Wenzhou Medical University for retrospective analysis. Results GAS infections in children mostly were seen as tonsillitis (38.0%), while in adults were partly skin infections (72.7%). Experimental markers including CRP, WBC, PCT and ASO can increase. At present, GAS is sensitive to most of the conventional antibiotics. Conclusion If taking good advantages of antibiotics, the prognosis of GAS infections can be really excellent and the dead case is
