Abstract:
Objective To retrospectively review the efficacy and side effects of intense pulsed light (IPL) and red light emitting diode(LED) in the treatment of steroid-dependent dermatitis. Methods Seventy patients with steroid-dependent dermatitis mainly manifesting as facial telangiectasis were treated with IPL for an average of 3.49 sessions with a 4-week interval. The energy density of IPL varied from 20 to 23 J/cm2, pulse width from 2.6 to 5.0 ms, and delay from 15 to 20 ms. Meantime, 197 patients with steroid-dependent dermatitis, who mainly presented with facial skin sensitivity, were treated with red LED (633 ± 3 nm wave length) twice a week for an average of 4.23 sessions. The energy density of red LED was 128 J/cm2, and the irradiation lasted 20 minutes at each treatment. The efficacy and adverse reactions were assessed and recorded for each treatment. Results The total response rate was 88.57% for IPL, and 83.76% for red LED. There was a significant difference in the clinical efficacy between triple-pulse and double-pulse IPL (?字2 = 8.14,P < 0.05). No severe adverse reaction was observed in any of the patients. Conclusion IPL and red LED are both effective in treating steroid-dependent dermatitis.
