TAILIEUCHUNG - Microscopy, is that an effective diagnostic tool for bacterial vaginosis?

Bacterial Vaginosis (BV) is a shift or disturbance in balance of vaginal microflora, the normal vaginal microflora consisting of Lactobacillus is replaced by over growth of other commensal bacteria. Other characteristic of BV is increase in vaginal pH. Clinically BV presents as increased thin homogenous vaginal discharge with or without burning micturation and itching. It is an extremely common health problem in women with sexually transmitted infections, pregnant women and women attending Gynecology clinics. Outcome of BV infection in pregnancy is low birth weight (LBW) infants and preterm births which is preventable. There are different methods to diagnose BV but microscopy is cost effective and easy. Aim of our study was to know the prevalence of BV in our study population and compare the diagnostic efficacy of two different microscopic methods. It was a prospective, cross sectional study with purposive sampling. Two swabs of vaginal discharge from posterior fornix were collected and processed using Amsel’s criteria and Nugent score. In this study prevalence of BV was 16%. Amsel’s criterion is sensitive and specific whereas Nugent score method is sensitive and specific. Hence Nugent scoring is more effective and reliable method in comparison to Amsel’s criteria. Clinical and microbiological investigations should be done in both symptomatic as well as asymptomatic pregnant women at regular interval which is beneficial in controlling persistence and recurrence of BV. | Microscopy, is that an effective diagnostic tool for bacterial vaginosis?
