| 3 | Effectiveness of Gardnerella vaginalis culture and Nugent scoring in identifying bacterial vaginosis in pregnant women显示文摘Background:Bacterial vaginosis(BV),a lower genital tract syndrome,has been linked to adverse pregnancy outcomes and is regarded as the prevalent type of vaginal infection in females of childbearing age.Objectives:To determine the accuracy of Nugent scoring and Gardnerella vaginalis culture in the diagnosis of bacterial vaginosis(BV)among pregnant women attending antenatal clinic in Nnamdi Azikiwe University Teaching Hospital,Nnewi,Nigeria.Method:This cross-sectional study evaluated biospecimen from 333 pregnant women enrolled through systematic random sampling technique.Biospecimens of vaginal discharge were tested for BV infection using Amsel’s criteria,Nugent’s score and culture of G.Vaginalis.Using Amsel’s criteria as a“gold standard”,the Nugent’s score and culture of G.vaginalis were estimated.Results:Prevalence of 26.12%,25.82% and 28.20% of BV was found using Amsel criteria,Nugent’s method and culture of G.vaginalis,respectively.No statistical relationship exists between socio-demographic characteristics and BV(P>0.05).Sexual exposure,and vaginal hygienic practices influences BV(P<0.05)infection and also with fishy odor during or after sexual intercourse,Gardnerella morphotypes,Bacteroides morphotypes and BV(P<0.05).An inverse relationship existed between lactobacilli morphotypes and BV.The prevalence of HIV was 5.41% and 16 out of 18 had BV diagnosed using Amsel criteria.Nugent method correlated strongly with Amsel criteria(P<0.05).In comparison with Amsel criteria,it had 78.16% sensitivity,92.68% specificity,79.07% positive predictive value,92.31% negative predictive value and 88.89% accuracy rate.This was in contrast distinction to the culture of G.vaginalis,which had 56.32%sensitivity,81.70% specificity,52.13% positive predictive value,84.10% negative predictive value and 75.08% accuracy rate.Conclusion:Nugent method correlated strongly with Amsel criteria(P<0.05)and had 78.16% sensitivity,92.68% specificity,79.07% positive predictive value,92.31% negative predictive value and 88.89% accuracy rate.Contrariwise,the culture of G.vaginalis had 56.32% sensitivity,81.70% specificity,52.13% positive predictive value,84.10% negative predictive value and 75.08% accuracy rate for BV diagnosis. | Chijioke Ogomegbunam Ezeigwe George Uchenna Eleje Chidebe Christian Anikwe David Chibuike Ikwuka Boniface Chukwuneme Okpala Kindness Chidi Irikannu Emeka Philip Igbodike Emmanuel Umegbolu Ngozichukwu Uzoewulu Olufunke Onaadepo Malarchy Ekwunife Nwankwo Onyecherelam Monday Ogelle Choice Chinemerem Nworgu Jide Uzowulu Uzoigwe Ifeoma Frances Okwuonu Chisom Godswill Chigbo LazarusUgochukwu Okafor Chinekwu Sochukwu Anyaoku Chukwuemeka Okwudili Ezeama Charlotte Blanche Oguejiofor Joseph Ifeanyichukwu Ikechebelu | 2023 | Infectious Diseases Research2023，4，2： | 0 |
