Abstract | BACKGROUND: PURPOSE: To compare the efficacy and safety of two commonly used concentrations of intralesional triamcinolone acetonide (ILT) (5 mg/mL vs 10 mg/mL) in the treatment of patchy AA on the scalp. PATIENTS AND METHODS: A retrospective comparative study that included 85 patients diagnosed with patchy AA on the scalp, who were treated with monthly injections of ILT. Patients were divided into Group 1 that received 5 mg/mL and Group 2 that received 10 mg/mL. The response rate (defined as the percentage of patients who achieved complete hair regrowth) and the side effects were compared between the two groups after completion of three treatment sessions, and recurrence was assessed after 1-3 years. RESULTS: Demographic composition of the two groups was comparable. The difference in response rate and the side-effects between the two groups were not statistically significant. Complete hair regrowth was noted in 43.5% of patients in Group 1 and 53.8% of those in Group 2 (P=0.340). About 17% and 25% of patients in Group 1 and Group 2, respectively, developed minor local side-effects (P=0.354), and almost 45% of patients from both groups had recurrence after 1-3 years. Disease duration exceeding 6 months correlated with poor treatment response. CONCLUSION:
