Background: Bacterial vaginosis (BV) is one of the most common infections in childbearing age.
Aim: To compare the efficacy of metronidazole (once-daily 0.8% MTZ in situ gel) versus twice-daily conventional MTZ vaginal gel in the treatment of bacterial vaginosis (BV).
Material and methods: All patients who presented to Assiut Women Health Hospital- Egypt with symptoms suggestive of BV were counseled to participate in the study. One hundred-four eligible participants were randomly assigned to either MTZ in situ gel or a conventional vaginal gel. All participants were followed-up twice after one and 4 weeks of the beginning of treatment to ensure cure of infection and any side-effects.
Results: Demographic criteria of the participants were matched in both groups. The cure rate after one week from the treatment was 74.5% in the in situ gel group and 63.8% in the conventional vaginal gel group (P=0.252), while after 4 weeks, the cure rate showed significant difference in the in situ gel group as compared to the conventional vaginal gel group (66.7%) and (40.4%), respectively (P=0.009).
Conclusion: Once daily in situ MTZ gel (0.8%) is more effective than twice-daily conventional gel after four weeks of treatment with nearly same side effects. These findings confirm the use of this novel and efficient modality of long-term treatment of BV.
