[Effect of an oral hyperproteic nutritional supplement in malnourished elderly patients in nursing homes]. / Efecto de un suplemento nutricional oral hiperproteico en pacientes desnutridos ubicados en residencias geriátricas.

INTRODUCTION: Nutritional problems develop complications in geriatric patients and increase their morbidity and mortality. Hyperproteic nutritional supplements are one of the options to improve nutritional deficiencies. OBJECTIVES: To assess the beneficial effect and tolerance of one hyperproteic nutritional supplement (Ensure Plus High Protein, Abbott Laboratories, S.A.) in malnourished subjects over 65 years. METHODS: Observational, prospective, open, multicenter study. We included malnourished subjects over 65 years living in nursing homes located in Spain. Malnutrition was considered as GNRI score < 92 or BMI < 19. Before inclusion, we obtained signed informed consent of patients or their relatives. All participants received Ensure Plus High Protein for 8 weeks. The primary endpoints were changes observed in weight, BMI and GNRI. RESULTS: We analyzed 255 evaluable patients valid for intention-to-treat (ITT) analysis and 243 for the per-protocol (PP) analysis; 69% (n = 172) were female and 31% (n = 77) male. The average protein amount administered was 51 g/day. At the end of the study, statistically significant differences (p < 0.001) were found in weight, BMI and GNRI when compared to baseline, both in the ITT and the PP analysis. The average weight increase was (mean +/- SE) 2.86 +/- 0.13 kg for PP analysis; 80% of participants (n = 202) achieved a weight gain > 1 kg and 96 patients (39.5% PP analysis) had a weight gain > 7%. CONCLUSIONS: The addition of a hyperproteic oral nutritional supplement contributes positively in improving the nutritional status of our study malnourished geriatric patients in terms of significant increase in body weight, BMI and GNRI.

Introducción: Los problemas nutricionales complican la evolución de los pacientes geriátricos y aumentan su morbilidad y mortalidad. Los suplementos nutricionales hiperproteicos constituyen una de las maneras de mejorar la ingesta nutricional. Objetivos: Determinar el efecto beneficioso y la tolerancia de un suplemento nutricional hiperprotéico (Ensure Plus High Protein®, Abbott Laboratories, S.A.) en sujetos mayores de 65 años diagnosticados de desnutrición. Métodos: Estudio observacional, prospectivo, abierto y multicéntrico. Se incluyeron sujetos > 65 años diagnosticados de desnutrición, ubicados en 59 residencias geriátricas en España. Se consideró desnutrición una puntuación GNRI < 92 ó IMC < 19. Antes de la inclusión, se obtuvo el consentimiento informado firmado de los pacientes o sus familiares. Todos los participantes tomaron Ensure Plus High Protein® durante 8 semanas. Las variables principales de valoración fueron peso, IMC y GNRI. Resultados: Se analizaron 255 pacientes válidos para el análisis ITT y 243 para el análisis PP, 69% (n = 172) mujeres y 31% (n = 77) hombres. La cantidad de proteína media administrada fue 51 gr./día. Al final del estudio, los tres parámetros principales -peso, IMC y GNRI- presentaron diferencias estadísticamente significativas (p < 0,001) con respecto a la visita basal, tanto en el análisis ITT como en el análisis por protocolo. El incremento de peso medio fue de (media ± EE) 2,86 ± 0,13 kg para el análisis PP. El 80% de los participantes (n = 202) consiguió un incremento de peso > 1 kg y 96 pacientes (39,5% análisis PP) obtuvieron una ganancia ponderal > 7%. Conclusiones: La adición de un suplemento nutricional oral hiperproteico contribuye favorablemente en la mejoría del estado nutricional de los pacientes geriátricos malnutridos en estudio en términos de incremento significativo del peso corporal, IMC y GNRI (AU)
