Systematic Review of Recovery of Spinal Cord Injury With Antioxidant Therapy

Abstract

The objective of the paper is to analyze the frequency and efficacy of experimental studies with antioxidant therapy. A search was conducted in the pubmed.gov database using the keywords "antioxidants" AND "spinal cord injury", from January 2000 to December 2015, resulting in 686 articles. Studies of non-traumatic injuries, non-antioxidant therapies, absence of neurological and functional evaluation, and non-experimental studies were excluded, leaving a total of 43 articles. The most used therapies were melatonin (16.2%), quercetin (9.3%), epigallocatechin and edaravone (6.9%). The most frequent route of administration was intraperitoneal (72.09%). The dose and mode of administration varied greatly, with a single dose being the most commonly used (39.53%). The time elapsed from trauma to treatment was 0-15 minutes (41.8%), 15-60 minutes (30%) and over 60 minutes (10.6%). Histological analysis was performed in 32 studies (74.41%). The BBB scale was the main functional measure applied (55.8%), followed by the inclined plane test (16.2%) and the Tarlov scale (13.9%). Positive outcomes were observed in 37 studies (86.04%). minutos (10,6%). A análise histológica foi realizada em 32 estudos (74,41%). O sistema de escala BBB foi a principal medida funcional aplicada (55,8%), seguida de teste com plano inclinado (16,2%) e a escala de Tarlov (13,9%). Os desfechos positivos foram observados em 37 estudos (86,04%). A heterogeneidade da terapia antioxidante com diferentes tipos, doses e medições observadas limita a comparação da eficácia. Protocolos padronizados são necessários para tornar possível a tradução clínica.Descritores: Antioxidantes; Traumatismos da medula espinal; Neurologia; Neurocirurgia; Revisão.

Se realizó una búsqueda en la base de datos pubmed.gov utilizando las palabras clave "antioxidants" (antioxidantes) AND "spinal cord injury" (trauma raquimedular), de enero de 2000 a diciembre de 2015, y se encontraron 686 artículos. Se excluyeron los estudios de lesiones no traumáticas, terapias no antioxidantes, con ausencia de evaluación neurológica y funcional y los estudios no experimentales, quedando 43 artículos. Las terapias más utilizadas fueron melatonina
