Successful Treatment of Vitiligo Vietnamese Patients with VitilinexÂ® Herbal Bio-Actives in Combination with Phototherapy
BACKGROUND: Vitiligo is an acquired pigmentary disease, that causes progressive loss of melanocytes, resulting in hypopigmented skin patches. Current treatments aim at stopping the disease progression and achieving repigmentation of the amelanotic areas. Corticosteroids, surgery, topical immunomodulators, total depigmentation of normal pigmented skin and phototherapy are current treatment options for vitiligo although phototherapy remains the treatment of choice. There is no documented evidence that herbal bio-active products may also be effective treatment options for vitiligo.
AIM: This study aimed to investigate the efficacy and safety of VitilinexÂ® (herbal bio- actives) alone and in combination with UVB narrowband (311 nm) phototherapy, in the treatment of localised stable or active forms of vitiligo.
MATERIAL AND METHODS: Sixty two subjects with mean age 34.5 years (range: 18-58 years) with mild to moderate vitiligo, consisting of 36 females and 26 males were randomly divided into three treatment groups â€“ Group A (13 females, 10 males ) treated with VitilinexÂ® alone; Group B (12 females, 11 males) were treated with VitilinexÂ® in combination with narrowband UVB (311 nm) phototherapy for 15 seconds, using a handheld lamp and Group C (8 females, 8 males ) were treated with nbUVB (311 nm) phototherapy alone, for 15 seconds over a 12-week period.
RESULTS: In Group A, 9 patients (39%) achieved outstanding improvement with a re-pigmentation rate higher than 75%, with 2 patients experiencing total repigmentation. 6 patients (26%) had marked improvement with a repigmentation rate between 50-75% while 5 patients (22%) showed a moderate response between 25-50% re-pigmentation rate. 3 patients (13%) had minimal or no improvement. In Group B, 16 patients (69.5%) achieved outstanding improvement with a re-pigmentation rate higher than 75%, with 12 patients experiencing total re-pigmentation. 4 patients (17.5 %) achieved a marked improvement with a re-pigmentation rate between 50-75%; 2 patients (8.7%) showed a moderate response with a re-pigmentation rate between 25-50%. 1 (4.3%) patient had minimal or no improvement. In Group C, 6 patients (37.5%) achieved a re-pigmentation rate higher than 75%, with 2 patients experiencing total re-pigmentation. 4 patients (25%) achieved marked improvement with a re-pigmentation rate between 50-75% while 3 patients (18.75%) had a re-pigmentation rate between 25-50%. 3 patients (18.75%) had minimal or no improvement.
CONCLUSION: VitilinexÂ® herbal bio-actives in combination with nbUVB is a more effective treatment option for vitiligo with 87% of the patients achieving a re-pigmentation rate higher than 50%, compared to VitilinexÂ® alone (65%) or nbUVB alone (62.5%).
