Predictive value of serum myeloperoxidase activity for thrombosis of arteriovenous fistulas

Abstract: Myeloperoxidase is a proinflammatory protein that appears as a result of increased oxidative stress. It plays an important role in the promotion and progression of atherosclerosis. The aim of this study was to determine the importance of MPO as a predictive parameter for thrombosis of arteriovenous fistula (AVF). The study involved monitoring patients with AVFs for hemodialysis over a period of 2 years. There were 41 patients, 19 (46%) men and 22 (54%) women, with mean age of 65 ± 12.7 years. Routine laborator… Show more

“…This degrades the extracellular matrix, facilitating migration of smooth muscle cells in the formation of neointimal hyperplasia [8]. In clinical studies on arteriovenous fistulas with stenosis and thrombosis of the venous conduit, elevated levels of myeloperoxidase were found in the region of intimal hyperplastic stenosis of the fistula [11]. Recent investigations have shown that increased levels of C-reactive protein, high reactivity of interleukin-6 and tumor necrosis factor alpha, and inflammatory cells (macrophages and lymphocytes) may have a possible connection with the extent of neointimal hyperplasia in patients with arteriovenous fistula dysfunction.…”

“…Recentemente, a atividade da MPO e sua função na doença inflamatória têm sido associada a várias doenças, como trombose de fístulas arteriovenosas (Stolic et al, 2014), oxidação de lipoproteínas (Boudjeltia et al, 2013), fluorose (Zhang et al, 2013), otite média crônica (Garça et al, 2013) e brucelose aguda (Karahocagil et al, 2012).…”

“…O comprimento de onda utilizado para monitorar a atividade no espectrofotômetro UV foi de 412 nm. Uma unidade de MPO foi definida como a quantidade de MPO que hidrolisa o substrato e gera cloridrato de taurina para consumir 1,0 μmol de TNB por minuto a 25 ° C. Por fim, não há valor de normalidade definido para a atividade da MPO de acordo com a literatura prévia (Stolic et al, 2014;Boudjeltia et al, 2013;Karahocagil et al, 2012).…”
