研究目的
To evaluate the clinical efficacy of Erbium: YAG (Er:YAG) laser with RecoSMA in the treatment of stable psoriasis vulgaris lesions.
研究成果
The results of the clinical trial confirm the effectiveness of RecoSMA technology for the treatment of skin manifestations of psoriasis vulgaris that are progressing slowly and stably, and they demonstrate an improvement in the quality of life of patients after the course of treatment. According to the protocol used, skin pathological process has reached complete remission in 87.5% of patients and a significant improvement in 9.8%. The length of remission of the patients' psoriasis reaches 4 years at the moment, which is comparable to results achieved by alternative methods of psoriasis laser treatment.
研究不足
The study was limited to patients with stable psoriasis vulgaris lesions. The method may not be effective for widespread and unstable psoriasis vulgaris or for drop-shaped, pustular, or erythrodermic psoriasis.
1：Experimental Design and Method Selection:
The study was conducted between October 2013 and December 2015 at the Linline network of clinics. The follow-up period is 4 years. The treatment was carried out using the Er:YAG laser (2940 nm) with the treatment head SMA (space-modulated ablation)—RecoSMA technology.
2：Sample Selection and Data Sources:
One hundred and fifteen patients signed up for the study and one hundred and twelve completed it. The mean age of the study group was
3：3 ± 7 years. List of Experimental Equipment and Materials:
Er:YAG laser (2940 nm) with the treatment head SMA (space-modulated ablation)—RecoSMA technology.
4：Experimental Procedures and Operational Workflow:
The treatment program consisted of a series of laser sessions RecoSMA technology with a 3–4 weeks interval between them. One pass of the laser were made with a superposition of pulses of ~30%, covering all psoriatic plaques and the surrounding tissue at a distance
5：5 cm. Data Analysis Methods:
The clinical effectiveness of laser therapy using the RecoSMA technology was evaluated by studying how the values of the PASI and DLQI changed over the course of the treatment.
