Clinical and pathogenetic assessment of cyclosporine efficacy in the complex therapy of non-segmental vitiligo patients

Abstract

BACKGROUND: Vitiligo is a chronic disease of unknown etiology, characterized by the appearance of depigmented spots on various areas of the skin, rarely on mucous membranes, and discolored hair due to destruction and reduction of melanocytes. While not life-threatening, vitiligo significantly impacts the psychoemotional aspect. Studies assessing the quality of life of vitiligo patients reveal the presence of depression in these individuals. In addition to depression, a high susceptibility to anxiety, stigmatization, sleep disturbances, adaptation, and problems in personal relationships have been identified. The prevalence of depression and anxiety among vitiligo patients is comparable to other dermatological conditions such as atopic dermatitis, acne, psoriasis, and urticaria. This underscores the need to seek new means and methods for treating this condition. AIM: Clinical assessment of the effectiveness of using cyclosporine in combination with UVB 311 nm and monotherapy with UVB 311 nm for vitiligo. MATERIALS AND METHODS: The study involved 40 patients with progressive vitiligo. All patients were randomly divided into two groups. Group 1 (20 individuals) underwent a course of cyclosporine therapy in combination with UVB therapy, while Group 2 (20 individuals) received monotherapy with UVB 311 nm. The duration of the treatment was 6 months. The extent of the affected area relative to the body surface area was evaluated using the VES index (Vitiligo extent score) on a vitiligo calculator. The impact of the disease on the quality of life was assessed using the VitiQoL scale (vitiligo-specific quality-of-life instrument). RESULTS: All patients included in the study completed the full course of treatment. Group 1 (20 individuals) underwent a course of cyclosporine therapy in combination with UVB therapy, while Group 2 (20 individuals) received monotherapy with UVB 311 nm. Patients in the combined therapy group experienced earlier stabilization of the skin process compared to those receiving monotherapy with UVB 311 nm. Additionally, Group 1 demonstrated more pronounced repigmentation of vitiligo lesions and significant improvement in quality of life compared to Group 2. CONCLUSION: Cyclosporine in combination with narrowband phototherapy at 311 nm demonstrated good clinical efficacy and significant improvement in quality of life for non-segmental vitiligo patients. Cyclosporine is well-tolerated, has a low spectrum of side effects, and can be used long-term for patients with active vitiligo.
