Patients in group B were treated with vaginal clindamycin 100 mg daily for 15 days. After 5-10 days from the end of the treatment the patients returned for the follow-up. Results. After treatment the vaginal discharge was completely absent in group A, and reduced in group B. The itching occurred only in 10% of patients in each of the two groups. The improvement of constipation occurs only in the group A (P=0.002). Vaginal swabs resulted negative in both groups in particular for Gardnerella V. Conclusion.
