RESUMO
Realizamos estudo transversal com um grupo homogêneo constituído de 90 pacientes com insuficiência aórtica crônica importante, de etiologia reumática. Foram realizadas dosagens plasmáticas de citocinas proninfmamatórias a saber Fator de necrose tumoral alfa( TNF ), receptores solúveis de TNF tipo I e II ( sTNFRI e sTNFRII ), interleucina 6 ( IL-6 ) e seu receptor solúvel ( IL-6R ), inteleucina 1-beta ( IL-1B ), antagonista do receptor de IL-1 ( IL1-RA ) e endotelina-1. Realizado o polimorfismo –308 do gene do TNF. Observamos níveis aumentados de TNF, IL-6 e sTNFRI em relação a indivíduos normais. Pacientes sintomáticos e assintomáticos tiveram níveis semelhantes de citocinas. O polimorfismo TNF 1/2 foi mais frequente em indivíduos assintomáticos. O aumento dos diâmetros ventriculares correlacionou-se a diminuição dos níveis de sTNFR II. /We made a transversal study in a homogeneous group of rheumatic patients with chronic severe aortic regurgitation. We determined plasma levels of the following proinflamatory cytokines Tumor necrosis factor-alpha ( TNF ) and its soluble receptors type I and II ( sTNFR I and sTNFR II ), Interleukin-6 ( IL-6 ) and its soluble receptor ( IL-6R ), interleukin-1 beta ( IL-1 beta ), antagonist of the IL-1 receptor ( IL1-RA ) and endothelin-1. The -308 genetic polimorphism os the TNF gene was made. Plasma levels of TNF, IL-6 and sTNFRI were increased in asymptomatic and symptomatic in relation to controls. There were similar levels of cytokines in asymptromatic and symptomatic patients. The polimorphism TNF 1/2 was more frequent in asymptomatic patients. Increase of ventricular diameters was correlated to decrease...
