NCT07641725

Brief Summary

Pemphigus vulgaris (PV) is a chronic, potentially life-threatening autoimmune mucocutaneous disorder that significantly impairs patients' quality of life. While systemic corticosteroids and immunosuppressants remain the standard of care, many patients suffer from persistent, painful oral lesions that exhibit delayed healing or poor response to conventional systemic protocols. This clinical trial investigates the efficacy and safety of supportive topical interventions: clobetasol propionate 0.05% mouthwash and photobiomodulation therapy (PBMT)-a non-invasive approach designed to accelerate tissue repair, and their combination. The primary objective is to identify effective adjunctive topical therapies that can facilitate the healing of oral erosions, mitigate pain, and potentially allow for a reduction in systemic medication dosages, thereby minimizing long-term treatment-related complications and improving overall patient outcomes.

Outcome Measures

Primary Outcomes (4)

  • Pemphigus Disease Area Index (PDAI)

    The PDAI is a validated clinical scoring system used to assess disease activity in pemphigus vulgaris. It evaluates the extent and severity of skin and mucosal lesions, including lesion number and size. Higher scores indicate more severe disease activity. These scores are categorized as follows: 250 points associated with disease activity, distributed as follows: * 120 points for the skin * 120 points for the mucous membranes * 10 points for the scalp. 30 points for tissue damage Disease activity, as well as the number and size of lesions in each specific region, are considered crucial factors within this scoring system. In the context of this research, only the component assessing oral mucosal involvement will be utilized.

    Patients will be followed up on Days 7, 14, 21, 28, 42, 60, and 90

  • Oral Disease Severity Score (ODSS)

    The ODSS is a site-specific scoring system designed to assess the severity of oral mucosal involvement in pemphigus vulgaris. It quantifies the number, size, and distribution of oral lesions, as well as their functional impact on pain and eating ability. The total score is 106 points, calculated by summing the region score, the disease activity score, and the pain score.

    Patients will be followed up on Days 7, 14, 21, 28, 42, 60, and 90

  • Autoimmune Bullous Skin Disorder Intensity Score (ABSIS)

    The ABSIS is a composite score used to assess disease severity in autoimmune blistering disorders. It includes evaluation of the extent of skin and mucosal involvement and incorporates patient-reported symptoms such as pain and difficulty in eating. It provides both objective and subjective measures of disease severity. The overall assessment consists of a total score of 208 points (100 points for skin lesions, 100 points for oral lesions, and 8 points for self-reported discomfort during eating). In this study, only the oral mucosal component of the score will be used. This component evaluates 20 distinct anatomical sites in the oral cavity. A score of 0 (absence of any lesion) or 1 (presence of a lesion) is assigned to each site, resulting in a maximum score of 20 points for the extent of oral lesions. The second part of the score is dedicated to symptom severity. It details the degree of discomfort experienced while eating and drinking, with a maximum score of 10 points

    Patients will be followed up on Days 7, 14, 21, 28, 42, 60, and 90

  • physician Global Assessment (PGA)

    The PGA is a clinician-reported global measure of overall disease severity and activity. It is based on the physician's overall clinical judgment, integrating physical examination findings and disease extent into a single numerical score. It consists of a 10-point visual analogue scale (VAS) that ranges from 0 (representing ideal health or complete clearance) to 10 (representing the worst possible disease state). Physicians rate the patient according to their global clinical impression of the disease severity.

    Patients will be followed up on Days 7, 14, 21, 28, 42, 60, and 90

Secondary Outcomes (4)

  • Systemic Corticosteroid Dosage During Treatment of Oral Lesions

    in day 30,60,90

  • Oral Health Impact Profile-14 (OHIP-14)

    Patients will be followed up before the treatment and on Days 30,60,90

  • Hamilton Anxiety Rating Scale (HAM-A)

    before the treatment and after in days 30,60,90

  • Hamilton Depression Rating Scale (HAM-D)

Study Arms (3)

Arm 1: Clobetasol propionate 0.05% Mouthwash

EXPERIMENTAL

Drug: Clobetasol propionate 0.05% mouthwash * Use 3 times daily. * Rinse and hold in the mouth for 3 minutes per application. * Do not swallow. * Duration: 4 weeks. Follow-up instructions: After 4 weeks of therapy, if the patient achieves complete clinical remission, taper the frequency gradually until discontinuation, similar to the tapering of systemic steroids (e.g., reduce from three times daily → twice daily → once daily → every other day → stop).

Drug: Clobetasol propionate 0.05% Mouthwash

Arm 2: Photobiomodulation Therapy

EXPERIMENTAL

Patients in the laser group received photobiomodulation therapy using a 650 nm diode laser (continuous wave mode). The laser parameters were as follows: * Wavelength: 650 nm * Output power: 100 mW * Mode: Continuous wave * Radiant exposure (energy density): 4 J/cm² per session * Exposure duration: 20 seconds per session (adjusted according to the spot size/area of the lesion to achieve the target fluence of 4 J/cm²) Treatment was applied without contact by maintaining a distance of 1 mm from the lesion and making continuous circular movements from the periphery toward the center of the lesions. Sessions were performed twice a week for a total duration of 30 days (approximately 8-9 sessions, depending on the exact scheduling).

Device: diode laser for photobiomodulation

Arm 3: Combination Therapy

EXPERIMENTAL

All patients in the intervention arm received combined treatment consisting of: Clobetasol propionate 0.05% mouthwash, rinsed three times daily for 3 minutes each time, for 30 days, in addition to photobiomodulation therapy using a 650 nm diode laser (continuous mode, 100 mW, 4 J/cm², 20 seconds per session). The laser therapy was administered twice weekly for 30 days. Treatments were performed by a trained clinician according to standardized protocol.

Masking Details
This study employs a single-blind design where participants remain unaware of their specific group allocation. Due to the technical nature of the interventions, the clinicians administering the treatments cannot be blinded. To maintain participant blinding, those in the clobetasol-only group will undergo a "sham" photobiomodulation procedure, which replicates the visual and auditory cues of the laser device without delivering active energy. Conversely, participants in the PBMT-only group will be provided with a placebo mouthwash, identical in appearance and administration to the active clobetasol rinse. To further ensure objectivity and minimize bias, all clinical outcomes will be evaluated by independent assessors who are not involved in the treatment allocation or administration process.
