Abstract

Background: Psoriasis is a chronic inflammatory disease involving multiple organ systems and affecting approximately 2% of the world's population. Plaque psoriasis is the most common clinical type of the disease. In addition to drug treatment methods, low-power intravascular laser is known as a supportive therapy with wavelengths from 632.8nm-670nm and power from 0-6 mW, which modulates immunity and improves circulation. However, there are very few studies on the effectiveness of this method in Vietnam. Objective: To describe clinical features in patients with plaque psoriasis and evaluate the results of treatment of plaque psoriasis with intravascular low level laser irradiation at Can Tho Hospital of Dermato-Venereology in 2022-2023. Material and method: A cross-sectional study was conducted at Can Tho Hospital of Dermato-Venereology, including 76 patients diagnosed with plaque psoriasis, who were treated with intravascular low level laser. Results: The average onset age was 44.32 ± 14.2. The current injury position on the scalp had the highest rate (92.1%). Significant treatment effectiveness was recorded after 5 sessions with a PASI reduction rate of 32.89% and this rate continues to increase after treatments. After ending the treatment, it was noted that most patients have improved with a rate of 97.7% of patients achieving average to good effectiveness. Conclusion: Psoriasis is distributed at all ages, mainly concentrated in the working age, lesions can appear in any position but concentrate the most on the scalp; endovenous laser is an effective method in treating plaque psoriasis with a gradually increasing PASI reduction rate after each treatment.
