Platelet-rich plasma for genital lichen sclerosus: analysis and results of 94 patients. Are there gender-related differences in symptoms and therapeutic response to PRP?

Abstract

Background

Lichen sclerosus is a chronic relapsing inflammatory dermatosis with a predilection for anogenital skin in 85%–98% of cases and is more prevalent in women (3%) than in men (> 0.07%).

Objectives

The purpose of this study was to investigate gender differences in clinical presentation and therapeutic response to treatment with platelet-rich plasma (PRP), an emerging innovative strategy for LS.

Methods

Forty-three male and 51 female patients affected by LS were evaluated. Each patient was subjected to PRP treatment (1 infiltration every 15 days, for 3 times).

Results

The PRP procedure was well tolerated by all patients and an overall significant decrease in symptoms was reported 6 months after PRP infiltration. Reduction in pain and burning sensation was significant in both gender but more accentuated in women than in men, whereas reduction of itching was similar. On the contrary, dyspareunia evidenced sex-related difference since a significant diminution was observed only in male.

Conclusions

This study demonstrates that PRP based therapy may exert a relevant role in LS patient management due to its effect on Quality of Life (QoL) and sexual function in both gender. In addition, the study underlined gender-related differences in severity of symptoms and disease age onset.
