NCT04577027

Brief Summary

Vitiligo is a chronic disease with an unpredictable clinical course, characterized by the appearance of white macules and patches on the skin and mucous membranes due to the disappearance of melanocytes in the affected area. It affects approximately 0.5% - 2% of the population worldwide and may occur at any age. Vitiligo is caused by a dynamic interplay between genetic and environmental risks that initiates an autoimmune attack on melanocytes in the skin.

Outcome Measures

Primary Outcomes (1)

  • clinical improvement through VASI score

    VASI score will be calculated for each patient at start, every 4 weeks and 6 months after the last session. VASI = ∑ all treated sites \[number of hand units\] X \[% residual depigmentation\].

    9 months

Secondary Outcomes (3)

  • Patients satisfaction

    9 months

  • percent of repigmentation

    9 months

  • Histopathological evaluation

    9 months

Study Arms (1)

vitiligo patients

EXPERIMENTAL

Thirty Patients complaining of generalized non segmental vitiligo will be recruited in this study. They will be chosen from the attendants of the out-patient clinics of Dermatology, Assiut university hospital. six patches will be selected in each patient.

Drug: Topical travoprost 0.004% solutionDevice: Fractional CO2 laserDevice: Excimer laserOther: Combination therapyOther: Excimer laser and travoprostOther: fractional CO2 laser and topical travoprost

Interventions

30 Patches treated with Topical Travoprost 0.004% solution: Topical travoprost 0.004% solution once daily (1 drop for each 2.5 x 2.5 cm2) for 3 months.

vitiligo patients

30 Patches treated with Fractional CO2 laser: Fractional CO2 laser sessions twice monthly for 3 months, parameters settings as follows: Energy\\ dot 100mj, pulse duration 5ms, density level 17, pattern: array, depth level 1, 2 passes used

vitiligo patients

30 Patches treated with Excimer laser: Excimer laser sessions will be repeated twice weekly on the selected patch only, The starting dose will be 200 mj /cm2, an increase of 100 mJ/cm2 in the following session if no erythema appears, an increase of 50 mJ/cm2 every session till the appearance of erythema that lasts 24 hours or more.

vitiligo patients

30 Patches treated with Combination therapy: Fractional CO2 laser twice per month followed by application of topical travoprost 0,004% daily and excimer laser twice weekly .

vitiligo patients

30 Patches treated with Excimer laser twice weekly and topical travoprost once daily for 3 months
