Study - Therapeutic efficacy of intralesional triamcinolone acetonide versus intralesional triamcinolone acetonide plus lincomycin in the treatment of nodulocystic acne

Background: Intralesional triamcinolone is an established therapy for cysts of acne. However, intralesional antibacterials have not been used earlier. Aim: To compare the efficacy of intralesional triamcinolone with that of a combination of intralesional lincomycin and intralesional triamcinolone in nodulocystic acne. Material and Methods: Ten patients of nodulocystic were injected with intralesional triamcinolone acetonide (2.5 mg/ml), while nine patients were given lincomycin hydrochloride (75 mg/ml) in addition to the intralesional triamcinolone. They were followed up 48 hrs, one week and one month later. Results: At one week, 7 patients (70%) treated with injection triamcinolone showed 66% improvement, whereas all 9 (100%) patients treated with lincomycin and triamcinolone showed 100% improvement which was stable at one month. Conclusion: A combination of intralesional triamcinolone and lincomycin is superior to intralesional triamcinolone alone in the treatment of nodulocystic lesions of acne.
