Brief Summary:
This is a prospective, randomized study in women of reproductive age with vulvar lichen sclerosus. Participants will be randomly assigned by investigators using a computer-generated sequence to receive either combined dynamic quadripolar radiofrequency (DQRF) plus topical corticosteroid therapy or topical high-potency corticosteroid therapy alone. Clinical outcomes, patient-reported outcomes and tissue-level changes evaluated by histology, elastin histochemistry, and immunohistochemistry for estrogen, androgen receptors and superoxide dismutase 2 (SOD2) will be assessed before and after treatment, and during follow-up at 3, 6, and 12 months. Safety will be monitored throughout the study. Histochemical and immunohistochemical analyses will be performed in a subset of 10 patients per group before the treatment and at 3 months after the completion of treatment.
Detailed Description:
This is a prospective, randomized study conducted in women reproductive age with vulvar lichen sclerosus. Computer-generated randomization using an electronic spreadsheet will be used by investigators to assign participants to study groups.
Study groups Group 1: topical high-potency corticosteroid therapy according to the standardized regimen, followed by combined Dynamic Quadripolar Radiofrequency (DQRF) therapy initiated 2 weeks after the start of corticosteroid treatment. DQRF therapy will be administered using a small vulvar applicator in a total of four sessions, performed at two-week intervals.
Group 2: topical high-potency corticosteroid therapy according to a standardized regimen.
Study assessments Clinical assessment At baseline and each follow-up visit, participants will undergo standardized vulvar examination with documentation of objective signs (skin color changes, sclerosis, fissures, erosions, scarring and architectural changes) and symptom severity. Clinical severity will be assessed using a structured clinician-rated vulvar lichen sclerosus severity score. Standardized photo documentation will be performed.
Patient-reported outcome measures
Patient-reported outcomes will be assessed using validated questionnaires:
* Numeric Rating Scale (NRS) for pruritus, vulvar pain, burning, dryness and dyspareunia;
* Vulvar Quality of Life Index (VQLI);
* Short Form-12 Health Survey (SF-12);
* Female Sexual Function Index (FSFI). Histological and tissue-level assessment
Histochemical and immunohistochemical analyses will be performed in a subset of 10 patients per group. Vulvar punch biopsy specimens will be obtained before initiation of therapy and after completion of treatment for:
* immunohistochemical analysis of estrogen receptors, androgen receptors and superoxide dismutase 2 (SOD2) expression;
* histochemical assessment of elastin fiber staining intensity and distribution using a standardized elastin stain, with semi-quantitative grading and/or digital image analysis.
Safety assessment Adverse events related to topical therapy, radiofrequency treatment will be recorded throughout the study.
Follow-up period Participants will be followed longitudinally before the treatment, at the end of treatment, and at 3, 6, and 12 months after completion of therapy to evaluate short-term response, durability of clinical improvement, and disease recurrence.
