Conjugate treatment with high concentration normobaric oxygen and hyaluronic acid for vaginal atrophy: a prospective study.

OBJECTIVE: Vulvovaginal atrophy is a condition closely related to low circulating estrogen levels, with post-menopause being the main cause. However, patients of childbearing age may also present with these symptoms due to treatments that reduce estrogen production. Local estrogen therapy is the causal treatment of local symptoms, but it is not always accepted and is often abandoned by patients. In recent years, alternative therapies have been proposed: fractional CO2 laser or the conjugate treatment with normobaric oxygen and hyaluronic acid, the latter being the subject of this study. The study aimed to evaluate the effectiveness of conjugate topical treatment with normobaric oxygen and hyaluronic acid.

PATIENTS AND METHODS: 50 patients were evaluated and treated with 5 applications of 15 minutes each, every 15 days, with Caressflow®. All patients presented at least one of the symptoms related to vulvovaginal atrophy: dryness, burning, and dyspareunia. In all cases, vulvoscopy, colposcopy, and cervicovaginal cytology were performed. The patients were interviewed with an analogic scale (VAS) concerning the severity of symptoms before and after the treatment. Colposcopy and PAP-smear were assessed by mean of Vaginal Health Index Score (VHI) at baseline and at the end of the treatment.

RESULTS: All patients completed the treatment scheme and presented with a significant improvement in subjective symptoms. The colposcopy and PAP-smear performed 10 days after the end of the last treatment showed a significant improvement in the appearance and elasticity of the vaginal epithelium and the cytological picture, which showed, in the sample taken after treatment, hyaluronic acid vesicles within the cell cytoplasm.

CONCLUSIONS: This study corroborates the data presented in the latest published papers on the effectiveness of treatment with normobaric O2 and hyaluronic acid on vaginal atrophy. Efficacy has been confirmed both in terms of subjective symptoms reported by the patients and objective improvement at colposcopy and PAP-smear cytology.
