“…We hypothesized that when the hepatocytes are presented with excessive amounts of purines for catabolism, in patients who subsequently develop PE, there is activation of xanthine oxidase, the more toxic isoenzyme of xanthine oxidoreductase, with the generation of reactive oxygen species (ROS) as byproducts. 5 Excessive ROS production overwhelms the normal antioxidant ability of the tissues to produce oxidative stress. We are currently investigating hepatocyte pathophysiology in PE.…”

“…Además, evidencias indirectas, atribuyen también a la placenta, la generación de ácido úrico en pre-eclampsia. Así, en esta patología se ha mostrado aumento de la actividad de xantina oxidasa en la circulación feto-placentaria 29 ; así como de la conversión de xantina reductasa a xantina oxidasa, con la consecuente generación de radical superóxido y peróxido de hidrógeno [29][30][31] . Además, y más importante para la visión planteada en este trabajo, es el aumento del recambio de células trofoblásticas, cuyos fragmentos pueden alcanzar la circulación materna 32 , y constituir el sustrato para la generación de ácido úrico.…”

“…Sin embargo, es fácil asumir que estos altos niveles de ADN fetal (libre o asociado a micropartículas) presente en pre-eclampsia deben ser metabolizados por la madre, constituyéndose en el sustrato para la generación de purinas y finalmente ácido úrico 31 .…”

“…As the precursor of uric acid, abnormal level of xanthine in body has been found to be closely related to many diseases, including hyperuricemia, gout, xanthinuria, perinatal asphyxia and pre-eclampsia [2][3][4][5][6]. Meanwhile, xanthine is also an important biomarker in the food industries [7].…”
