Tratamento dietético da hiper-homocisteinemia na doença arterial periférica

Abstract: IntroduçãoA doença arterial periférica (DAP) é definida como uma doença arterial das extremidades que reduz o fluxo sanguíneo durante o exercício ou, em estágios avançados, mesmo em repouso 1 . Estudos epidemiológicos mostram que a prevalência de DAP varia de 1,6 a 12% 2,3 .As doenças do aparelho circulatório foram as principais causas de morte entre os brasileiros em 2007 (28,2%) 4 e na população mundial (18 milhões) 5 ; dentre as várias etiologias, a aterosclerose foi a causa mais comum. Entre os paciente… Show more

“…The plasma homocysteine concentrations recorded in our study ranged from 17.47 to 59.80 μmol/L, which are of similar levels to those observed in patients with hyperhomocysteinemia and are thought to contribute to premature vascular disease 79,18. In addition, hyperhomocysteinemia developed in animals without significant changes in the serum lipid profile, which suggests that there was no interference from hypercholesterolemia.…”

“…Patients with hyperhomocysteinemia have pre-existing intimal hyperplasia in saphenous vein biopsies, an increasing rate of vein graft stenosis and increased bypass graft failure 8. Hyperhomocysteinemia may also be associated with accelerated disease progression 8,9. However, the effects of hyperhomocysteinemia on endovascular procedures are unknown.…”

“…For hyperhomocysteinemia, folic acid and vitamin B6 and B12 supplementation and dietary changes can reduce plasma levels effectively, but the impact this has on cardiovascular disease morbidity and mortality is a controversial subject and different studies contradict each other [10][11][12] .…”

“…Assim, tanto a deficiência de folato quanto a de Cbl podem ocasionar transtornos hematológicos, neurológicos e cardiovasculares (Andrès, Loukili et al, 2004), por serem necessárias às reações de metilação e devido as suas influências no metabolismo da homocisteína (Venâncio, Burini et al, 2004). …”

“…Cbl como co-fator, para que possa ser remetilada à metionina e, assim, não se acumular (Venâncio, Burini et al, 2004). Após a metilação da tHcy, a metionina formada é convertida em S-adenosilmetionina (SAM), que é o principal doador do grupo metil para a síntese de DNA, de proteínas e de neurotransmissores (Trková, Kapras et al, 2000;Govindaiah, Naushad et al, 2009;Kalhan e Marczewski, 2012).…”
