Comparison of vaginal gel isoflavones versus no topical treatment in vaginal dystrophy: results of a preliminary prospective study

OBJECTIVE

Vaginal dystrophy due to hypo-oestrogenism takes advantage of local and systemic oestrogens to balance the vaginal ecosystem and improve tissue hydration. Women who do not accept/tolerate hormone therapy can use intravaginal isoflavones to relieve vaginal dryness. The aim of this study was to investigate the clinical effect of a vaginal gel formulation containing isoflavones compared with no topical treatment in women with vaginal dystrophy.

MATERIAL AND METHODS

In a multicentre, controlled, parallel-group study, menopausal women with vaginal dystrophy were randomized to vaginal gel (EG) or no topical treatment (NT) for 4 weeks. EG contained isoflavones, Lactobacillus sporogenes, Calendula officinalis extract and lactic acid (Estromineral Gel, Rottapharm-Madaus). All patients received daily oral isoflavones plus L. sporogenes. Clinical evaluations were performed at time 0, 2 and 4 weeks.

RESULTS

186 women were recruited, 103 in the EG group and 83 in the NT group, mean age 53.7 years, postmenopausal for 4.1 years. The severity of itching, burning, vulvovaginal erythema, vaginal dryness and dyspareunia were significantly reduced during EG treatment compared with the NT group.

CONCLUSIONS

The combination of oral and topical isoflavones was shown to be more effective than oral treatment alone in reducing the problems of postmenopausal vaginal dystrophy.

[Efficacy of Lactobacillus Rhamnosus GR-1 and of Lactobacillus Reuteri RC-14 in the treatment and prevention of vaginoses and bacterial vaginitis relapses]

AIM

The aim of this study was to investigate the efficacy of the use of Lactobacillus rhamnosus GR-1 and of Lactobacillus reuteri RC-14 administrated orally in the treatment and prevention of vaginoses and bacterial vaginitis relapses.

METHODS

The study enrolled 50 women in good health, aged between 18 and 48 years, with assessed diagnosis of bacterial vaginosis and vaginitis. The women were randomized in two groups: group A comprised 25 patients with bacterial vaginitis and group B comprised 25 patients with vaginosis. Each patient was administered an antibiotic therapy and subsequently a therapy with Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 (Dicoflor Elle, Dicofarm, Roma, Italy) with two tablets daily for 15 days. After one week from the end of the therapy all patients have been controlled by vaginal swab and microscopic analysis of vaginal secretion.

RESULTS

At the end of the study 46 patients had a complete Lactobacilli recolonization, two patients had no colonization and two dropped out. The results showed that 92% of the enrolled patients benefited from the treatment.

CONCLUSION

The results of the present study shows that Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14, taken orally, were helpful in vaginosis and bacterial vaginitis treatment and in relapse prevention, as they can re-establish the vaginal ecosystem remarkably.
