New approaches in the nutritional treatment of advanced chronic kidney disease.

INTRODUCTION: Patients with advanced chronic kidney disease (ACKD) have a high prevalence of malnutrition. The dietary restrictions that we usually apply in terms of macro and micronutrients force our patients to follow dietary guidelines that deviate from healthy patterns. OBJETIVES: To determine if a personalized nutritional intervention program, minimizing the usual restrictions would be justified in case it improved the evolution of kidney disease compared to standard treatment. SECUNDARY OBJETIVES: To determine changes in nutrient intakes and in anthropometric and biochemical parameters, as well as quantify episodes of hyperkalemia. MATERIAL AND METHODS: A single-center, randomized and controlled educational intervention clinical trial was conduct in patients from the ERCA outpatients clinic at the Complejo Hospitalario Universitario de Albacete. 75 patients were included, assigning 35 to a Control group and 40 to the Intervention group with 1-year follow-up. The nutritional status was determined using anthropometric data, body composition by Bioimpedance, blood and urine biochemical parameters and a 24-h recall questionnaire. The nutritional intervention was carried out in three different ways: individual, collective and telephone recall. RESULTS: At the beginning of the study, the BMI showed a situation of weight excess with a mean of 28.83 kg/m2 (5.4) in men and 26.96 kg/m2 (4.09) in women. 70% of our patients had overweight. The abdominal circumference was 105.3 cm (10.2) and 92.3 cm (13.7) for men and women respectively without significant changes throughout the study. The percentage of fat mass (FM) was high in both groups for men and women throughout the study. We did not find biochemical parameters of malnutrition and only significant differences were observed in glomerular filtration rate (GFR), which increased in the intervention group. No patient presented any episodes of hyperkalemia during the study. The energy intake in both groups showed an inadequate distribution of macronutrients with a poor intake of carbohydrates (CH) that was supplemented with an excess of fat. In the case of micronutrients, we did observe an increase in potassium and fiber intakes with a decrease in sodium and phosphorus in the intervention group. CONCLUSIONS: Malnutrition is not exclusively an intake defficit and encompasses both the problems derived from a deficit and an excess of nutrients intake. Un to 70% of our patients showed weight excess and a fat mass higher than desirable. The implementation of an individualized nutritional education program, including a vegetables and fiber rich diet, less atherogenic, not only did not cause electrolyte alterations but also slowed the progression of kidney disease.

Introducción: El paciente con enfermedad renal crónica avanzada (ERCA) presenta una elevada prevalencia de malnutrición. Las restricciones dietéticas que aplicamos habitualmente en cuanto a macro y micronutrientes obligan a nuestros pacientes a seguir pautas dietéticas alejadas de los patrones saludables.ObjetivoDeterminar si un programa de intervención nutricional personalizado, minimizando las restricciones habituales estaría justificado si mejorase la evolución de la enfermedad renal comparado con el tratamiento estándar.Objetivos secundariosDeterminar los cambios en las ingestas de nutrientes y en los parámetros antropométricos y bioquímicos, así como los episodios de hiperpotasemia.Material y métodosSe realizó un ensayo clínico de intervención educativa, unicéntrico, randomizado y controlado en los pacientes de la consulta ERCA del Complejo Hospitalario Universitario de Albacete. Se incluyeron 75 pacientes, asignando 35 en un grupo control y 40 en el grupo de intervención con seguimiento a un año. La situación nutricional se determinó mediante datos antropométricos, composición corporal por bioimpedancia, parámetros bioquímicos en sangre y orina y cuestionario de recuerdo de 24 h. La intervención nutricional se realizó de tres formas: individual, colectiva y recuerdo telefónico.ResultadosAl inicio del estudio, el IMC mostró una situación de exceso de peso con una media en hombres de 28,83 kg/m2 (5,4) y de 26,96 kg/m2 (4,09) en mujeres. El 70% de nuestros pacientes mostraron exceso de peso. La circunferencia abdominal fue de 105,3 cm (10,2) y 92,3 cm (13,7) para hombres y mujeres, respectivamente, sin cambios significativos a lo largo del estudio. El porcentaje de masa grasa (MG) fue elevado tanto hombres como en mujeres durante todo el estudio. ... (AU)

Introducción: las estrictas restricciones dietéticas que imponemos en la enfermedad renal crónica avanzada (ERCA) tienen un impacto negativo en la calidad de vida. Objetivo: determinar si estas restricciones están justificadas y si un programa de educación nutricional mejoraría los parámetros de calidad de vida relacionada con la salud (CVRS). Material y métodos: realizamos un ensayo clínico de intervención educativa, unicéntrico, randomizado y controlado en los pacientes de la consulta ERCA de Albacete. Se incluyeron 75 pacientes, 35 en el grupo control y 40 en el de intervención. Se realizó la valoración nutricional mediante valoración global subjetiva (VGS) e índice de masa corporal (IMC). Para medir la CVRS se empleó el cuestionario de salud SF-36. En el grupo intervención se realizó la intervención nutricional individual, colectiva y por recuerdo telefónico, adaptando a cada paciente el consejo dietético y ajustando las restricciones de forma personalizada. Resultados: la malnutrición medida por VGS fue del 20% en el grupo control y del 29,3% en el grupo intervención, donde mejoró aunque no fue significativo. El IMC mostró sobrepeso con una media de 28,83 (DE: 5,4) y 26,96 kg/m2 (DE: 4,09) respectivamente, sin cambios a lo largo del estudio. La intervención nutricional supuso una mejoría en las puntuaciones de todas las subescalas excepto en el dolor corporal. Además, los componentes físico y mental también mejoraron sus puntuaciones en el grupo intervención y empeoraron significativamente (p < 0,001) en el control. Conclusiones: la calidad de vida se puede mejorar en los pacientes con ERCA aplicando un programa de educación nutricional

Introduction: the strict dietary recommendations we impose on patients with advanced chronic kidney disease (ACKD) have negative impact on quality of life. Objective: determine whether such restrictions are justified and if an educational program can improve health-related quality of life (HRQL) parameters. Methods: we carried out an educational intervention, single center, randomized, controlled clinical trial on ACKD outpatients in Albacete. Seventy-five patients were included, 35 in the control group and 40 in the intervention group. Nutritional assessment was based on the Subjetive Global Assessment (SGA) and body mass index (BMI). We used the SF-36 health questionnaire to measure HRQL. In the intervention group we carried out individual, collective and telephone nutritional interventions, adapting diet advice and restrictions in a personalized way. Results: malnutrition measured by Subjective Global Assessment (SGA) in the control group was 20%; meanwhile, in the intervention group it was 29.3% and it improved at the end of the study, but not significantly. BMI showed overweight with a mean of 28.83 kg/m² (DE: 5.4) and 26.96 kg/m² (DE: 4.09), respectively, and did not change throughout the study. The nutritional intervention improved the score in all the subscales except for body pain score. Besides, mental and physical components also improved their scores in the intervention group and worsened them in the control group (p < 0.001). Conclusions: quality of life can be improved in ACKD patients applying an educational nutrition program
