Severity of protein-energy wasting and obesity are independently related with poor quality of life in peritoneal dialysis patients.

Protein-energy wasting (PEW) and poor health-related quality of life (HRQoL) are independently associated with morbi-mortality in continuous ambulatory peritoneal dialysis (CAPD). PEW may reduce HRQoL; however, we hypothesized HRQoL is affected differentially by PEW degrees or by individual criteria of nutritional status. AIM: To evaluate HRQoL according to PEW severity and nutritional status indicators in CAPD. This is a cross-sectional study in 151 patients. Subjective global assessment (SGA) was employed, and nutritional status classified as normal, mild-moderate PEW, and severe PEW. HRQoL was evaluated using Kidney Disease Quality of Life Short Form™, including physical (PCS), mental (MCS) and kidney disease (KDCS) components, and their subscales. Dietary intake, anthropometric and biochemical variables were measured. Forty-six percent of patients were well-nourished, 44% had mild-moderate PEW, and 10% severe PEW. Compared with well-nourished patients, those with mild-moderate (p=0.06) and severe (p=0.005) PEW had lower HRQoL score [68 (52-75), 55 (45-72), 46 (43-58), respectively]. PCS, MCS, and KDCS and their subscales had lower values as PEW was more severe. Patients with obesity and hypoalbuminemia had significantly lower HRQoL overall and component scores than their counterparts. Dietary intake was not associated with quality of life. In multivariate analysis obesity, PEW (by SGA), hypoalbuminemia, and low educational level predicted poor HRQoL (χ2 58.2, p<0.0001). As conclusion, PEW severity was related with worse HRQoL, either as overall score or in every component or subscale in CAPD patients. Poor HRQoL was predicted independently by PEW severity and obesity; additional predictors were hypoalbuminemia and low education.

El desgaste proteico-energético (DEP) y la mala calidad de vida relacionada con la salud (CVRS) se asocian de forma independiente con la morbimortalidad en diálisis peritoneal continua ambulatoria (DPCA). El DEP puede reducir la CVRS; sin embargo, planteamos la hipótesis de que la CVRS se ve afectada de forma independiente por los grados de DEP o por los criterios individuales del estado nutricional. Objetivo : Evaluar la CVRS de acuerdo a la gravedad de la DEP e indicadores del estado nutricional en DPCA.Este es un estudio transversal en 151 pacientes. Se empleó la evaluación global subjetiva (EGS) y el estado nutricional se clasificó como normal, DEP leve-moderada y DEP grave. La CVRS se evaluó mediante el uso del cuestionario Kidney Disease Quality of Life Short Form™, incluidos los componentes físicos (PCS), mentales (MCS) y de enfermedad renal (KDCS) y sus subescalas. Se midieron la ingesta dietética, las variables antropométricas y bioquímicas.El 46% de los pacientes tenía un estado nutricional normal, el 44% tenía DEP leve-moderada y el 10% DEP grave. En comparación con los pacientes bien nutridos, aquellos con DEP leve-moderada (p=0,06) y grave (p=0,005) tenían una puntuación de CVRS más baja (68 [52-75], 55 [45-72], 46 [43-58], respectivamente). Igualmente, la PCS, MCS y KDCS y sus subescalas tuvieron valores más bajos, conforme la DEP fue más severa. Los pacientes con obesidad e hipoalbuminemia tenían puntuaciones de CVRS general y de sus componentes significativamente más bajas que sus contrapartes. La ingesta dietética no se asoció con la calidad de vida. En el análisis multivariado la obesidad, el DEP (por EGS), la hipoalbuminemia y el bajo nivel educativo predijeron una mala CVRS (χ2 58,2; p<0,0001).En conclusión, la gravedad del DEP se relacionó con una peor CVRS, ya sea como puntuación global o en cada componente o subescala de los pacientes con DPCA. ...
