Abstract

Leprosy is caused by the bacillus Mycobacterium leprae (M. leprae), presenting the capacity to infect multiple individuals with infection of the upper airways. Hansen considered a public health problem, especially in underdeveloped countries and developing countries, due tothe presence of disabilities and social stigma. In recent years, the Low Intensity Laser Therapy (LILT) has been a therapy used in the repair process of healing chronic wounds, which is one of the most frequent  consequence of leprosy, with high series. The study included 13 patients with chronic wounds caused by leprosy, divided into two groups: 4 patients in the control group (GI) and 9 patients (GII) submitted to LTBI, with the parameters: 660 nm, 20 mW, the active medium InGaAlP (aluminum gallium indium phosphide), continuous emission, the output beam area of 0.04 cm ² dose 5 J / cm ² and 10 s per point. All participants were treated at the Hospital of Cologne Carpina (Parnaíba, PI) and some had more than one injury. The total experimental time was 4 months and the lesions were macroscopically evaluated, measured and photographed every 4 weeks. It was also carried out microbiological analysis of the lesions, to assess the presence of contamination in the region. The results allowed to verify that small injuries, not contaminated and in patients without associated diseases, showed tissue repair. On the other hand, the LTBI applied to large lesions in patients with diseases associated with the presence of contamination, showed an increase in the diameter of the wound, slowing the healing process. In conclusion, the results obtained in this study, the experimental conditions used, demonstrated the applicability of LILT in the process of tissue repair in patients with chronic wounds caused by leprosy uncontaminated and of smaller diameter. LILT favored the evolution of this process and allowed qualitative improvement in the appearance of lesions as well as pain and exudate reduction.
