Objective To investigate clinical characteristics of aerobic vaginitis AV) and its mixed infections for diagnosis efficiently. Methods From April 2008 to December 2008, 516 patients with vaginitis treated in Tianjin Medical University General Hospital were enrolled in this study. AV, bacterial vaginosis (BV) , vulvovaginal candidiasis (VVC), trichemonal vaginitis (TV) , and cytolytic vaginosis (CV) were diagnosed based on symptoms, sign and vaginal discharge examination. Results Among 516cases, AV cases were found in 14. 7% (76/516), and AV was common vaginal infection. AV mixed infections was diagnosed in 58% (44/76), including mixed with BV (45%, 20/44), mixed with VVC (30% , 13/44) , and mixed with TV (25% , 11/44). Those common symptom of AV were yellow vaginal discharge (63%, 20/32), more vaginal discharge (44%, 14/32). Vaginal pH value was usually more than 4. 5 (84% , 27/32). Vaginal cleanliness mainly was grade Ⅲ - V (88% , 28/32). Six cases with enterococcus faecium and 4 cases with streptococci were frequently isolated. The symptom and sign of mixed AV infection was atypical. Conclusions Aerobic vaginitis is a common lower vaginal infection and easily mixed with other pathogens, especially with BV, VVC or TV. When patients were diagnosed with AV or other vaginal infection, it should be mentioned whether those patients have mixed vaginal infection or AV.%目的 探讨需氧菌性阴道炎(AV)及其混合感染的临床特征,为AV的临床诊治提供帮助.方法 2008年4-12月,在天津医科大学总医院选取以外阴不适、阴道分泌物异常等阴道炎症状就诊的患者516例,联合其症状、体征及相关实验室检查诊断常见阴道炎,即AV、细菌性阴道病(BV)、外阴阴道假丝酵母菌病(VVC)、滴虫阴道炎(TV),分析AV及其混合感染的临床特征.结果 516例患者中,AV 76例,占14.7%(76/516),北中混合感染44例,占58%(44/76).在44例AV混合感染中,以合并BV多见,占45%(20/44);其次为合并VVC,占30%(13/44);合并TV占25%(11/44).单纯AV患者的常见症状主要为黄绿色稀薄脓性阴道分泌物(63%,20/32),其次为阴道分泌物增多(44%,14/32);阴道pH值常>4.5(84%,27/32),清洁度主要为Ⅲ～Ⅳ度(88%,28/32);细菌培养为粪肠球菌(6例)、链球菌(4例)等需氧菌.结论 AV是常见的下生殖道感染,易合并其他病原体感染,尤以合并BV、VVC及TV多见,混合感染时症状、体征不典型.在AV诊断中,注意有无合并其他阴道感染,并在诊断其他阴道感染时,注意是否合并AV.
