Diagnosis of Bacterial Vaginosis a Common Vaginal Infection among First-Time Antenatal Clinic Attendees: Evidence from a Tertiary Health Facility in North-West Nigeria

Background: Multiple adverse reproductive and pregnancy-related outcomes have been prospectively linked to bacterial vaginosis. Objective: To evaluate the prevalence in Northwest Nigeria of bacteria vaginosis among first-time antenatal clinic tourists. Plan, Environment and Subjects of the Study: A cross-sectional study carried out at the Ahmadu Bello University Teaching Hospital Antenatal Clinic, Zaria, north-west Nigeria. From April to June 2008, a total of 228 consecutive reservation customers were registered. Key Outcome Measures: presence of at least three of the following: I small white homogeneous discharge, (ii) microscopic hint cells, (iii) vaginal fluid pH > 4.5 (iv) release of fishy odor due to addition of alkali (10% potassium hydroxide) or positive whiff test (Amsel criteria) and (v) proportional proportion of morphotypic bacteria due to gram staining (Nugent score). Results: All 220 (96.5 percent) clients completed and evaluated the report. Using the Nugent score, bacteria vaginosis (BV) prevalence was 14.6 percent. Asymptomatic BV prevalence was 9.6 per cent . Of the patients with BV, eleven (34.4 percent) were symptomatic, while 21 (65.6 percent) were asymptomatic. There was no major difference between symptomatic and asymptomatic women in the prevalence of BV.

Conclusion: The overall incidence of bacterial vaginosis is high in pregnant women attending prenatal care bookings at ABUTH, Zaria and should therefore be regarded by clinicians as a significant condition in pregnant women. In high-risk women with prior adverse events such as low birth weight and preterm delivery, particularly in the second trimester, it is important to screen for BV. In order to further demonstrate the risk factors and potential adverse effects of Bacterial vaginosis, a larger prospective study should be carried out.
