RESUMO

In chronic kidney disease (CKD) patients, it would be desirable to reduce the intake of inorganic phosphate (P) rather than limit the intake of P contained in proteins. Urinary excretion of P should reflect intestinal absorption of P(inorganic plus protein-derived). The aim of the present study is to determine whether the ratio of urinary P to urinary urea nitrogen (P/UUN ratio) helps identify patients with a high intake of inorganic P.A cross-sectional study was performed in 71 patients affected by metabolic syndrome with CKD (stages 2-3) with normal serum P concentration. A 3-day dietary survey was performed to estimate the average daily amount and the source of P ingested. The daily intake ofPwas1086.5 ± 361.3mg/day; 64% contained in animal proteins, 22% in vegetable proteins, and 14% as inorganic P. The total amount of P ingested did not correlate with daily phosphaturia, but it did correlate with the P/UUN ratio (p < 0.018). Patients with the highest tertile of the P/UUN ratio >71.1 mg/g presented more abundant inorganic P intake (p < 0.038).The P/UUN ratio is suggested to be a marker of inorganic P intake. This finding might be useful in clinical practices to identify the source of dietary P and to make personalized dietary recommendations directed to reduce inorganic P intake.

RESUMO

Objetivos: El objetivo del presente estudio fue analizar la Calidad de Vida Relacionada con la Salud en pacientes con Enfermedad Renal Crónica Avanzada en prediálisis y su relación con el aclaramiento renal. Material y Método: Se estudiaron 124 pacientes en prediálisis y edad de 67,2±14,3 años (45% mujeres). Se realizó un estudio descriptivo y transversal, en el Servicio de Nefrología de Hospital Reina Sofía de Córdoba. Se utilizó el cuestionario KDQOL-SF, para el análisis de la Calidad de Vida Relacionada con la Salud. También se analizó el aclaramiento renal y la comorbilidad asociada. Resultados: En el KDQOL, las dimensiones más afectadas fueron: Situación Laboral, Carga de la Enfermedad Renal y Sueño. Las mujeres presentaron peor puntuación en Listado de Síntomas/problemas. En las dimensiones del SF-36, Salud General, Vitalidad, Función Física y Rol Físico, fueron las más afectadas. Las mujeres obtuvieron peor puntuación en Salud General, Vitalidad, Rol Físico, Dolor y Rol Emocional. Los pacientes con menor aclaramiento renal presentaron peores puntuaciones en Efectos de la Enfermedad Renal, Carga de la Enfermedad Renal y Función Sexual; y en Rol Físico y Salud General. Conclusiones: Los pacientes en prediálisis tienen disminuida su calidad de vida en las dimensiones Carga de la enfermedad renal, Sueño, Salud general, Vitalidad, Función física y Rol físico. El aclaramiento renal, aunque influye directamente en los síntomas derivados de la enfermedad renal, no parece ser tan influyente en la calidad de vida, siendo el sexo femenino, la edad y la comorbilidad asociada, las variables que más se asocian con peor calidad de vida


Objectives: The aim of this study was to analyse the Health-Related Quality of Life in patients with Advanced Chronic Kidney Disease in pre-dialysis and the relationship with renal clearance. Material and Method: We studied 124 patients with ACKD in pre-dialysis and age of 67.2±14.3 years (56 women, 45%). A descriptive and cross-sectional study was carried out in the Nephrology Service of the Reina Sofía Hospital in Cordoba. The KDQOL-SF questionnaire was used to analyse the Health-Related Quality of Life. The renal clearance and associated comorbidity were also analysed. Results: In the KDQOL, the most affected dimensions were: work situation, burden of kidney disease and sleep. Women presented worse score in list of symptoms / problems. In the dimensions of SF-36, General health, Vitality, Physical function and Physical role were the most affected. Women rated worse scores, significantly, in: General health, Vitality, Physical role, Pain and Emotional role. Patients with lower renal clearance presented worse scores in Effects of kidney disease, burden of kidney disease and sexual function; and in Physical Role and General Health. Conclusion: Patients in pre-dialysis have reduced their Health-Related Quality of Life in dimensions Burden of kidney disease, Sleep, General health, Vitality, Physical function and Physical role. Renal clearance, although directly influence the symptoms derived from kidney disease, does not seem to be so decisive in quality of life, being the female sex, age and associated comorbidity, the variables most associated with poorer quality of life

RESUMO

Introducción: La hipertensión arterial resistente o refractaria al tratamiento supone un serio problema de salud pública y aunque, no están claros los mecanismos por los que se produce esta resistencia, se sospecha que el consumo de sodio puede jugar un papel importante en el mantenimiento de la misma. Objetivo: Determinar si los pacientes con hipertensión resistente toman sodio oculto en los alimentos ingeridos en su dieta; así como relacionar este consumo con sus hábitos dietéticos. Pacientes y Métodos: Se estudiaron 32 pacientes con una media de edad de 74,25±6,38 años, (65,6% hombres y 34,4% mujeres). Se realizó un estudio descriptivo y transversal mediante entrevista estructurada sobre consumo de alimentos. Se estudió: edad, género, estado civil, presión arterial, responsable de la elaboración de las comidas, índice de masa corporal (IMC), consumo de sodio oculto en la dieta y percepción de los pacientes sobre su consumo de sodio. Resultados: Se encontró una ingesta media real de 3693,56±2330,97 mg de sodio. En el 59,4% de los casos las comidas las elaboraba otra persona diferente al paciente, siendo mayor el consumo de sodio en estos pacientes (3.709,44±529,37 frente a 3.677,69±649,27 mg. Respecto a la percepción sobre la cantidad de sodio ingerida, el 9,4% decían no tomar nada, el 56,3% poco, el 21,9% lo normal y el 12,5% bastante. Los que decían no tomar nada de sodio y lo normal, el mayor aporte lo hacían durante la cena; y los que decían tomar poco sodio y bastante, era en el almuerzo. Se encontró correlación significativa entre ingesta de sodio total e IMC (r=0,411, p<0,05). No se encontró relación entre consumo de sodio y hipertensión arterial. Conclusiones: Al menos en la muestra estudiada, no existe relación entre ingesta de sodio y presión arterial; existe una relación directa entre consumo de sodio y la persona que cocina. Por otro lado, la percepción que tienen estos pacientes respecto a su consumo de sodio es adecuada (AU9


Introduction: Arterial hypertension resistant or refractory to treatment is a serious public health problem and although it is unclear what mechanisms by which this resistance occurs, it is suspected that sodium intake can play an important role. Objective: To determine whether patients with resistant hypertension take hidden sodium in food eaten in your diet; and relate this intake with their dietary habits. Patient and Methods: 32 patients (65.6% men and 34.4% women) were studied with an average age of 74.25 ± 6.38 years. A descriptive and cross-sectional study using structured interview on food consumption. The following variables were studied: age, gender, marital status, blood pressure, responsible for the preparation of meals, body mass index (BMI), consumption of hidden sodium in the diet and perception of patients about their sodium intake. Results: A real average intake of 3693.56 ± 2330.97 mg sodium was found. In 59.4% of cases, the meals were made by someone different to the patient, being higher sodium intake in these patients (3709.44 ± 529.37 mg vs 3677.69 ± 649.27 mg). Regarding the perception of the amount of ingested sodium, 9.4%: ate nothing, 56.3%: little, 21.9%: normal and 12.5%: quite. Those who said they ate no sodium and normal intake, the largest contribution was made during dinner; and those who said eating low sodium, and quite, was at lunch. Significant correlation between total sodium intake and BMI (r = 0.411, p <0.05) was found. No relationship between sodium intake and blood pressure was found. Conclusions: At least in the studied sample, there is no relationship between sodium intake and blood pressure; there is a direct relationship between sodium intake and the person who cooks. Furthermore, the perception in these patients regarding their sodium intake is adequate (AU)
