Study Details

Brief summary:

Vitiligo is a chronic acquired disease characterized by well defined white macules and patches affecting the skin. There are many treatment modalities available for vitiligo, however, none of them cure the disease. Visible red light has been shown to stimulates melanocyte migration and proliferation resulting in repigmentation of vitiligo patches. However, there are only a few studies published on the efficacy of red light in vitiligo. This is a prospective single-blind randomized clinical trial to assess efficacy of red light in the treatment of vitiligo.

Interventions and Outcome Measures

Arms

active comparator: Low intensity red laser

Patients with a vitiligo patch larger than 25cm2 will be recruited. The target patch will be divided into four quadrants. Two opposite quadrants will be shielded by foil and served as control, the third quadrant will be exposed to low intensity red laser (at 3 J/cm¬2), and the fourth quadrant will be exposed to high intensity red light (at 37 J/cm¬2).

Treatments will be given twice weekly for 10 weeks. This will be followed by assessments at 4, 8, and 12 weeks post treatment.

active comparator: High intensity red light

Patients with a vitiligo patch larger than 25cm2 will be recruited. The target patch will be divided into four quadrants. Two opposite quadrants will be shielded by foil and served as control, the third quadrant will be exposed to low intensity red laser (at 3 J/cm¬2), and the fourth quadrant will be exposed to high intensity red light (at 37 J/cm¬2).

Treatments will be given twice weekly for 10 weeks. This will be followed by assessments at 4, 8, and 12 weeks post treatment.

no intervention: No treatment1 (covered)

Patients with a vitiligo patch larger than 25cm2 will be recruited. The target patch will be divided into four quadrants. Two opposite quadrants will be shielded by foil and served as control, the third quadrant will be exposed to low intensity red laser (at 3 J/cm¬2), and the fourth quadrant will be exposed to high intensity red light (at 37 J/cm¬2).

Treatments will be given twice weekly for 10 weeks. This will be followed by assessments at 4, 8, and 12 weeks post treatment.

no intervention: No treatment2 (covered)

Patients with a vitiligo patch larger than 25cm2 will be recruited. The target patch will be divided into four quadrants. Two opposite quadrants will be shielded by foil and served as control, the third quadrant will be exposed to low intensity red laser (at 3 J/cm¬2), and the fourth quadrant will be exposed to high intensity red light (at 37 J/cm¬2).

Treatments will be given twice weekly for 10 weeks. This will be followed by assessments at 4, 8, and 12 weeks post treatment.

Interventions

Primary outcome measure

  • Change in the modified VASI score compared to baseline. [ Time Frame: assessments at 2, 4, 6, 8 and 10 weeks during treatment then at 4, 8, and 12 weeks post treatment ]
