ABSTRACT

Objetivo. Determinar el efecto de los polifenoles del vino tinto (variedad tannat) sobre el estado antioxidante y el estrés oxidativo en hipertensos. Material y métodos. Estudio prospectivo, aleatorizado en 20 varones hipertensos, estadio I, entre 30 y 70 años, divididos aleatoriamente en 2 grupos; el primer grupo (n=10) ingirió vino por un mes y el grupo control (n=10) no ingirió vino. Se realizaron pruebas bioquímicas basales y a los 30 días. Se midieron enzimas antioxidantes: glutatión peroxidasa (GP), catalasa y superóxido dismutasa (SOD), estrés oxidativo por medición del malonildialdehído (MDA) sérico y el estado antioxidante total (TAS). Resultados. El vino tannat cotiene 134,08 mg/L de antocianincas, polifenoles totales: 1822,02 mg/L e inhibición de DPPH (CI 50%)=51 mg/ml. En los hipertensos, el consumo moderado de vino tinto aumentó el estado antioxidante (TAS) y la actividad de las enzimas SOD y GP. Conclusión. En hipertensos estado I, el vino tannat incrementó el estado antioxidante.


Objectives. To determine the effect of the polyphenols of red wine on the antioxidant status and oxidative stress on hypertensive patients. Material and methods. A prospective, randomized study was carried on in 20 volunteers hypertensive males, stage 1, between 30-70 year-old They were randomly divided into two groups: the intervention group (n=10) who consumed rd wine for one month, and the control group (n=10) who abstained from alcohol for one month. Blood samples were collected before and after wine consumption and were used for analysis of whole blodd glutathione (GP), catalase and superoxide dismutase (SOD), plasma malondialdehyde (MDA) and serum total antioxidant status (TAS). Results. Tannat wine content was 134,08 mg/L of antocyanines, total polyphenols 1822,02 mg/L and antioxidant state DPPH inhibition 51 mg/ml (CI 50%). In the hypertensive group, moderate consumption of red wine patients increased the plasma total antioxidant status (TAS) and the activities of the antioxidant enzymes SOD and GP. Conclusion. In hypertensive persons, stage I, red wine consumption increased the antioxidant status.
