[Assessment of diet in patients with chronic kidney diseases without dialysis and relationship with the nutritional status]. / Evaluación de la dieta en pacientes con enfermedad renal crónica sin diálisis y su relación con el estado nutricional.

BACKGROUND: Diet is one of the pillars of the treatment for patients with chronic kidney disease without dialysis (NDD-CKD). Despite this, very few studies have evaluated the diet in Spanish population. OBJECTIVE: To evaluate the diet of a group of patients with advanced CKD, comparing it with the recommendations, and its relation with nutritional status. MATERIAL AND METHODS: A cross-sectional study of 74 patients (39 men), with a mean age of 70.9 ± 13.6 years and creatinine clearance of 15.3 ± 2.1 mL/min. Biochemical, anthropometric and intake variables (3-day dietary record) were collected, comparing them with the recommendations for patients with CKD and, if they did not exist, with nutritional recommendations and objectives for the Spanish population. The nutritional status was assessed by modified criteria of protein-energy wasting (PEW). RESULTS: The mean energy intake was 23.2 ± 6.5 kcal/kg body weight/day, and the protein intake was 0.93 ± 0.2 g/kg body weight/day. Men had a higher intake of alcohol and vitamin D whereas women presented a higher intake of trans fatty acids and vitamin B1. In addition, 91.4% of patients had high intake of phosphorus and 73% of potassium. Only 2.7% showed an adequate intake of vitamin D and 21.6% of folates; 18.9% of patients presented PEW. A positive correlation was found between albumin, body mass index (BMI) and creatinine clearance. CONCLUSION: Most patients with non-dialysis CKD do not meet dietary recommendations or nutritional goals, regardless of gender and PEW status, considering renal function as a limiting factor.

Evaluación de la dieta en pacientes con enfermedad renal crónica sin diálisis y su relación con el estado nutricional / Assessment of diet in patients with chronic kidney diseases without dialysis and relationship with the nutritional status

Introducción: la dieta en los pacientes con enfermedad renal crónica (ERC) sin diálisis es uno de los pilares de su tratamiento. A pesar de esto existen muy pocos estudios que hayan evaluado la dieta en esta población y ninguno en población española. Objetivo: evaluar la dieta de un colectivo de pacientes con ERC avanzada, comparándola con las recomendaciones, y su relación con marcadores del estado nutricional. Material y métodos: estudio transversal de 74 pacientes (39 hombres), con edad media de 70,9 ± 13,6 años y aclaramiento de creatinina 15,3 ± 2,1 mL/min. Se recogieron variables bioquímicas, antropométricas y de ingesta (registro dietético de tres días), que fueron comparadas con las recomendaciones para pacientes con ERC y, si no existían, con las recomendaciones y objetivos nutricionales para población española. Se valoró el estado nutricional mediante criterios modificados de desgaste proteico energético (DPE). Resultados: la ingesta energética media fue de 23,2 ± 6,5 kcal/kg peso/día y la ingesta proteica, de 0,93 ± 0,2 g/kg peso/día. Los hombres presentaban una ingesta mayor de alcohol y vitamina D y las mujeres, de ácidos grasos trans y vitamina B1. Un 91,4% presentaba ingesta elevada de fósforo y un 73%, de potasio. Solo el 2,7% presentaba ingesta adecuada de vitamina D y el 21,6%, de folatos. El 18,9% presentaba DPE. Se encontró una correlación positiva entre albúmina, índice de masa corporal (IMC) y aclaramiento de creatinina. Conclusión: la mayoría de los pacientes con ERC sin diálisis no cumplen las recomendaciones de ingesta ni los objetivos nutricionales, independientemente del sexo y de la situación de DPE, considerando la función renal como un factor limitante (AU)
