Avaliação do efeito do selênio no processo de reparação tecidual em pacientes com pé diabético

Abstract

Introduction: It is now known that diabetic foot ulceration is one of the main complications of diabetes, because it is of medical, social and economic importance. Several factors interfere in the correct healing of these wounds, one of them being oxidative stress. In view of this situation, measures are sought that act in these pathways, with selenium as an important component in the antioxidative defense of the organism. Objective: to analyze the evolution of the cicatricial process of the ulcer in the diabetic foot after the supplementation with selenium. Methods: An open, non-randomized clinical trial of 19 patients with diabetic wounds from the HURCG wound ambiance. Selenium supplementation was 100mcg for 60 days and skin biopsy was performed before and after selenium supplementation. These lesions were histomorphologically evaluated. Results: There was a predominance of males and 60-year-olds. After the use of selenium, vascular congestion, granulation tissue and fibrosis decreased, and there were no statistical differences in the other parameters (neutrophils, edema and monomorphonuclear cells). The edges of the ulcers presented hyperkeratosis and acanthosis, which were not influenced by selenium. Conclusion: supplementation with selenium improved congestion and decreased inflammatory components, such as granulation tissue formation and fibrosis.
