Abstract
Objetivo: Se estudió si el consumo de productos dietéticos bajos en proteína® mejora la calidad de vida y el estado nutricional en vitaminas B y homocisteína en pacientes con insuficiencia renal crónica (IRC). Material y métodos: La intervención nutricional se llevó a cabo durante 6 meses en un grupo de pacientes con IRC (28 hombres y 21 mujeres) divididos en dos grupos. El grupo control consumió la dieta prescrita para la IRC. El grupo experimental consumió una dieta en donde parte de los alimentos fueron sustituidos por los productos dietéticos bajos en proteína. El consumo de alimentos fue analizado mediante recordatorio de 24 horas. El estatus en vitamina B6 se determinó como αEAST en muestras de sangre. En plasma se analizaron los niveles de creatinina, urea, Vitamina B12 , folato y homocisteína. El impacto del consumo de los productos dietéticos sobre la calidad de vida de los pacientes se analizó mediante el cuestionario de salud SF-36. Resultados: Tras 6 meses de intervención nutricional,la ingesta proteica en el grupo experimental descendió un 40%. También se redujo la relación urea/creatinina y la actividad αEAST. Los resultados del cuestionario de salud SF-36 mostraron que los pacientes del grupo experimental obtuvieron mejores puntuaciones en las categorías de salud general y estado físico. Conclusiones: Los productos dietéticos bajos en proteína fueron muy bien aceptados por los pacientes y su uso permitió un mejor control de la ingesta proteica, mejorando el estado nutricional del paciente en B6 y su calidad de vida.
OBJECTIVE The aim of the study was to determine whether the consumption of low protein dietetic foods improved the quality of life and nutritional status for vitamins B and homocysteine in patients with chronic renal failure. METHODOLOGY This nutritional-intervention involved 28 men and 21 women, divided into two groups. The control-group consumed a low-protein diet prescribed, and the experimental-group consumed a diet in which some commonly used foods were replaced by low-protein dietetic foods. The study lasted 6 months. Food consumption was assessed by 24-h recall. Vitamin B6 as alphaEAST was measured in blood. Creatinine, urea, vitamin B12, folate and homocysteine were measured in plasma. The impact on the patients' quality of life from consuming the dietetic foods was assessed via the SF-36 questionnaire. RESULTS After 6 months, the protein intake among the experimental-group had decreased by 40%, and the urea/creatinine ratio and alphaEAST activity were also lower. The results of the SF-36 questionnaire show that the patients in the experimental-group obtained higher scores in the categories of general health and physical status. CONCLUSIONS The dietetic foods were very well accepted by all patients and their use allowed a better control of the protein intake, improved B6 status and a better quality of life.
