HIPERHOMOCISTEINEMIA TRATAMIENTO PDF

Abstract Moderate hyperhomocysteinemia and atherothrombosis. Elevated levels of plasma total homocys- teine are now accepted as an independent risk factor for premature atherosclerosis. Nutritional, environmental and genetic factors may contribute to increase the levels of homocysteine. The exact pathogenesis of vascular damage induced by homocysteine is still not completely understood.

Abstract Moderate hyperhomocysteinemia and atherothrombosis. Elevated levels of plasma total homocys- teine are now accepted as an independent risk factor for premature atherosclerosis. Nutritional, environmental and genetic factors may contribute to increase the levels of homocysteine. The exact pathogenesis of vascular damage induced by homocysteine is still not completely understood. Various mechanisms have been proposed, including a significant prooxidative activity, a stimulation of smooth muscle cells proliferation and an endothelial dysfunction.

Folate, pyridoxine and cyanocobalamin are important cofactors for homocysteine metabolism. In most cases, elevated homocysteine can be reduced by administration of vitamin supplements. It has not yet been demonstrated that reduction in mortality and morbidity can be achieved with these regimens.

However, food supplementation with folic acid has been recommended for treatment or prevention of homocysteine-related disorders in the North American population. Appropriate clinical trials are needed to evaluate the effect of lowering moderate homocysteine levels on atherosclerosis. Cristina R. En uno de estos estudios, el Fra-mingham Heart Study, se evaluaron individuos de ambos sexos No se ha establecido la dosis de vitaminas a utilizarse ni las posibles combinaciones a administrar de las mismas.
