Abstract
ObjectiveTo discuss the best bacterial combination for the diagnosis of Bacterial vaginosis (BV).
MethodsThis is a retrospective study, 230 BV-positive patients and 360 healthy women were enrolled based on the Amsel criteria and Nugent score.5 BV-associated bacteria, including Gardnerella vaginalis, Atopobium vaginae and Leptotrichia/Sneathia species, et al. were amplified by specific-PCR assay, the detection rate were compared between two groups.ROC curve and Kappa test were used to select the best combination.
ResultsThe detection rate of Gardnerella vaginalis, Atopobium vaginae, Leptotrichia/Sneathia species, Megasphaera species and Mobiluncus mulieris in BV group (91.3%,83.5%,39.1%,42.6% and 36.5% respectively) were markedly higher than that in healthy women (37.2%,14.4%,11.7%,8.9% and 5.6% respectively), χ2 value were 168.848,275.776,60.949,92.886 and 92.68, all P<0.05.The area under ROC curve of A.vag,G.Vag+A.vag,G.Vag+A.vag+Lepto,G.Vag+A.vag+Mega and G.Vag+A.vag+M.mul were 0.845,0.862,0.865,0.869 and 0.867, and the sensitivity and specifity were higher than 80%, the value of Kappa were larger than 0.75 (P<0.05).Thus, these five methods were coincident.
ConclusionDetection of Atopobium vaginae may be a better way for the diagnosis of BV.(Chin J Lab Med,2012,35:1167-1171)
