Utilisation of hydrogen peroxide in the treatment of recurrent bacterial vaginosis.

AIM: The authors have evaluated the real efficacy of using hydrogen peroxide for previously treated recurrent bacterial vaginosis that is resistant to other forms of treatment.
METHODS: The study included 58 women aged between 18 and 42 years old. Vaginal irrigations with 30 ml of hydrogen peroxide (3%) were prescribed in the evening for a week. The follow-up was carried out 3 months after the end of treatment.
RESULTS: The results clearly show that the use of hydrogen peroxide in vagina can eliminate the main symptoms of bacterial vaginosis, and in particular the malodorous leucoxanthorrhea in 89% of cases at 3 months after the end of treatment, a result that is comparable to that obtained using metronidazole or clindamycin as a vaginal cream. Moreover, hydrogen peroxide facilitates the restoration of normal vaginal bacterial flora (represented by H202-producing lactobacillus) in 100% of cases and normal acid pH (pH<4.5) in 98% of cases; it also fosters the disappearance of clue cells from vaginal smears and anaerobic pathogenic flora from vaginal secretions in 100% of cases. The amine test became negative in 97.8% of cases. All results underwent statistical analysis and were found to be statistically significant.
CONCLUSION: Hydrogen peroxide represents a valid alternative to conventional treatments for recurrent bacterial vaginosis, and associates the absence of collateral effects with low costs, excellent tolerability and real therapeutic efficacy.
