ABSTRACT
BACKGROUND: Bacterial vaginosis (BV) remains an enigmatic question. The term "osis" instead of "itis" is used because commonly, there are no inflammatory process associated with BV. However, leukocytes are often observed in it. METHODS: In a transversal study, we evaluated 1178 cases with diagnosis of BV by liquid-based cytology (more than 20% of clue cells), attended in general gynecologic private clinic. Depending of the presence of more than five leukocytes on average per field in immersion objective (1000×), the cases were divided in two groups: few or no leukocytes (< 5 leukocytes per field) (BV) and with leukocytes (≥ 5 leukocytes per field) (BV-L). The Fisher exact and Student t tests was applied to a confidence interval of 95%. The project was approved by the Ethic Committee of Federal University of Ceará, Brazil. RESULTS: The age between the groups was the only different socio-demographic variable. The assessment of vaginal discharge aspect had no characteristic aspect. Colposcopy findings suggesting colpitis and ectopy were more frequent in the group of BV-L, 7.1% and 6.9%, respectively. The study of the microbiology demonstrated in the BV-L group, more frequently co-occurrence of Candida sp (15.1%) than in BV group (1.5%) (P < .0001). The cellular atypia was present more frequently in the BV-L (9.6%) than in BV (5.7%) (P = .0116). CONCLUSION: The presence of leukocytes in BV (or BV-L) may suggest a mixed infection, ectopy influencing the vaginal milieu and even epithelial atypia.
