RESUMO
Objetivo: Los pacientes con enfermedad renal crónica (ERC) en hemodiálisis (HD) suelen presentar déficits cognitivos. Sin embargo, existen pocos estudios que hayan examinado el funcionamiento neuropsicológico de aquellos que reciben diálisis peritoneal (DP). Método: Se evaluaron las funciones ejecutivas, la velocidad de procesamiento y la memoria verbal en 27 pacientes en DP, 42 en HD y 42 participantes sanos (PS). La presión sanguínea sistólica y el tiempo total en terapia renal sustitutiva (TRS) se controlaron estadísticamente. Las asociaciones entre el rendimiento y los factores clínicos se analizaron mediante correlaciones y regresión múltiple. Resultados: El grupo DP presentó mejor ejecución respecto al HD en fluidez verbal, memoria de trabajo, flexibilidad cognitiva, planificación y toma de decisiones. El grupo DP mostró peor ejecución que el grupo PS en inhibición y memoria verbal. Las puntuaciones en las funciones ejecutivas se asociaron positivamente con los meses totales en DP, en TRS, en HD, la albúmina, el colesterol total y el fósforo, y de forma negativa con la ferritina. Conclusión: El funcionamiento ejecutivo global fue mejor en los pacientes en DP que en aquellos en HD. Los resultados muestran el efecto positivo de la DP sobre las funciones ejecutivas, lo que debe tenerse en cuenta a la hora de la elección de la TRS. Las asociaciones observadas entre los factores bioquímicos y el rendimiento muestran la importancia de mantener un adecuado estado nutricional en estos pacientes.(AU)
Background: Patients with chronic kidney disease on hemodialysis (HD) often have cognitive deficits. However, there are few studies that have examined the neuropsychological impairments of patients receiving peritoneal dialysis (PD). Methods: Executive functions, processing speed and verbal memory were assessed in 27 PD patients, 42 HD patients, and 42 healthy participants (HP). Systolic blood pressure and total time on renal replacement therapy (RRT) were controlled statistically. Associations between performance and clinical factors were analyzed using correlations and multiple regression. Results: The DP group showed better performance compared to the HD group in verbal fluency, working memory, cognitive flexibility, planning and decision making. The DP group showed worse execution than the HP group in verbal inhibition and memory. Executive function scores were positively associated with total months on PD, total months on RRT, total months on HD, albumin, total cholesterol, and phosphorus, and negatively with ferritin. Conclusion: Global executive functioning was more optimal in PD patients than in HD patients. The results show the positive effect of PD on executive functions, which must be taken into account when choosing the TRS. The associations observed between biochemical factors and performance show the importance of maintaining an adequate nutritional status in these patients.(AU)

BACKGROUND Cognitive problems are frequent in patients with end-stage renal disease (ESRD) treated with hemodialysis. However, previous studies used only a single cognitive screening test or a small number of cognitive indices, which is inadequate for an exhaustive evaluation of cognitive deficits. This case-control study aimed to evaluate cognitive function in patients with ESRD before and after hemodialysis at centers in southern Spain, and included analysis of associations between cognitive function and duration of hemodialysis, biochemistry, body composition, and treatment variables. MATERIAL AND METHODS Cognitive performance was evaluated in 42 healthy participants (HPs) and in 43 ESRD patients, before and after hemodialysis. The tests measured verbal and visual memory, sustained/selective attention, and processing speed. The diagnostic criterion for ESRD was a glomerular filtration rate.
