简要总结
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.
详细描述
Patients with pemphigus vulgaris often experience debilitating oral pain, which severely restricts their ability to maintain adequate nutrition and hydration. Furthermore, the presence of extensive oral ulcers and erosions poses a significant risk for secondary bacterial or fungal infections. These challenges underscore the clinical necessity for effective topical adjunctive treatments to complement systemic therapy. By enhancing local lesion management, these topical modalities aim to accelerate clinical.

盲法说明
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.
