    Abstract:
    BACKGROUND: Triamcinolone acetate injections are considered the first treatment option for keloids, but quite high proportions of keloids either do not respond to triamcinolone or develop recurrence. Beneficial effects of intralesional bleomycin have been recently shown in the treatment of keloids and hypertrophic scars. However, the efficacy of combination therapy using intralesional triamcinolone and bleomycin remains undetermined. OBJECTIVE: The purpose of this study was to evaluate the efficacy of using bleomycin and triamcinolone mixture to treat refractory keloids. MATERIALS AND METHODS: In total, 33 patients with resistant keloids (including 8 men and 25 women) and a mean age of 36.52 years (age range of 18-65 years) were enrolled in this study. A mixture of bleomycin (1 u/cc) with triamcinolone acetonide (13.3 mg/cc) was injected intralesionally into the keloids every 4 to 6 weeks for a maximum of 6 cycles. The clinical improvement was evaluated using the Japan Scar Scale (JSS) and the physician's global assessment of the flattening of the lesions. Side effects were also noted and recorded. RESULTS: In all patients, the total JSS scores decreased significantly after treatment (2.33 ± 1.05), compared with baseline (11.61 ± 2.59), ( p < .001); 26 keloids (78.8%) showed an excellent response (75%-100% flattening), 7 keloids (21.2%) showed a fair response (25%-75% flattening), and 0 keloids (0%) showed a poor response (<25% flattening). Observed side effects were ulceration (33.3%), hyperpigmentation (33.3%), hypopigmentation (15.15%), secondary infection (33.3%), and telangiectasis (15.15%). CONCLUSION: The combined use of bleomycin and triamcinolone offers a promising treatment option for individuals who have not responded well to traditional therapies.
