Topical 5% Minoxidil and Potent Topical Corticosteroid Versus Intralesional Corticosteroid in the Treatment of Alopecia Areata

Cairo University40 enrolled

Overview

Alopecia areata (AA) presents with circumscribed patches of non-scarring hair loss. It inflects a significant psychological and social burden. Many treatment options are used for the treatment of AA. Randomized controlled trials comparing intralesional and topical therapy and comparing combinations are few. The aim of this work is to evaluate the efficacy of combined topical 5% minoxidil and potent topical corticosteroid therapy compared to intralesional triamcinolone injection in alopecia areata

Outcomes

Primary Outcomes

Clinical assessment using SALT score (Severity of Alopecia Tool score)

SALT score is a quantitative assessment scale for the evaluation of percentage of scalp hair loss. The percent surface area of each of the 4 scalp is determined: Vertex (top): 40% (0.4) of scalp surface area; each side of scalp (right and left profile): each 18% (0.18) of scalp surface area; posterior aspect (back) of scalp: 24% (0.24) of scalp surface area. The percentage of hair loss in any of these 4 aspects is calculated as the percentage of hair loss multiplied by percent surface area of the scalp in that area. SALT score is the sum of product of each section in the above mentioned areas. SALT score is calculated before and after therapy. Lowest value: 0%: indicates abscence of clinical disease, Highest value: 100%: indicate 100% affection of the scalp

Time frame: 3 months

Secondary Outcomes

Dermoscopic evaluation

Dermoscopic assessment of the scalp is performed using DermaLite II Pro HR dermoscope, Germany. Dermoscopic examination is graded according to a scale provided by Trink and colleagues (2013). The percentage of dystrophic hairs was evaluated on a 4-point scale as followed: * 3= \>50% dystrophic hairs * 2 = 30-50% dystrophic hairs * 1 = 1-29% dystrophic hairs * 0 = no dystrophic hairs

Time frame: 3 months

Time frame: 3 months

Quantitative measurement of Interleukin-23 (IL-23)
