Superficial Cryotherapy Versus Microneedling in Alopecia Areata

Not Applicable

Completed

• Conditions: Alopecia Areata

• Registration Number: NCT04680234
• Lead Sponsor: Sohag University

Brief Summary

This study is randomized comparative analytical prospective study that included patients with mild and moderate alopecia areata. Patients was divided into two groups Patients in the first group underwent Superficial cryotherapy using dimethyl ether and propane (DMEP) at -57C (Cryotherapy group). Patients in the second group underwent Microneedling (Microneedling group). A total of six sessions were done at 2 weeks interval. Patients were followed-up for next 3 months to evaluate the persistence of hair regrowth after therapy. Patients were assessed at baseline and during follow up using photography, Dermoscopy, SALT score and regrowth scale.

Primary Outcome Measures

Name	Time	Method
Regrowth Scale	Change in regrowth scale from baseline to 3 months follow after end of sessions	0 score (regrowth \< 10%) no response; 1. score (regrowth 11-25%) poor response; 2. score (regrowth 26-50%) fair response; 3. score (regrowth 51-75%) satisfactory response; 4. score (regrowth ≥ 75%) excellent response.

Secondary Outcome Measures

Name	Time	Method
SALT score	Change in salt score from baseline to 3 months follow after end of sessions	SALT score is the sum of the percentage of hair loss in all the abovementioned areas. For example, if the percentage hair loss in vertex, right profile, left profile, and posterior aspect is 20, 30, 40, and 50% respectively; then, SALT score = (20 × 0.4) = (30 × 0.18) + (40 × 0.18) + (50 × 0.24) = 8 + 5.4 + 7.2 + 12 = 32.6.
