Context: Alopecia areata is a chronic non-scarring alopecia that involves scalp and/or body. Corticosteroids are the most popular drugs for its treatment. Aim: The aim of the study was to evaluate the therapeutic efficacy of intralesional injection of triamcinolone acetonide and platelet-rich plasma (PRP) in alopecia areata and to compare the efficacy of these modalities in alopecia areata. Settings and Design: This was a randomized controlled comparative study. Subjects and Methods: Forty patients were enrolled from the outpatient department and divided into two groups of 20 patients each. Group A and B randomly received intradermal triamcinolone acetonide suspension (10 mg/mL) and PRP, respectively, into the lesion using an insulin syringe in multiple 0.1 mL injections 1cm apart. The injections were repeated every 3 weeks till 12 weeks. The patients were evaluated by Severity of Alopecia Tool (SALT) score and photographically every 3 weeks till the end of 12 weeks and then at the end of 6 months. Statistical analysis used descriptive analysis along with Pearson chi-square test or Fisher exact test, paired samples, and independent samples t test or their nonparametric analogs for continuous variables. Results: The reduction in SALT score at each visit with respect to baseline was greater in the triamcinolone group as compared to PRP group. This signifies greater effect of triamcinolone in alopecia areata. Around 50% patients in triamcinolone group and 5% patients in PRP group showed grade V improvement. Pain during intralesional injection was higher in the PRP group. Conclusion: Both intralesional triamcinolone and PRP were found to be efficacious in alopecia areata but the latter produced lesser improvement.
