          Abstract

          Abstract Objective: dietary advice provided through a nutritional intervention program (NIP) is recommended by renal clinic guidelines to prevent or treat malnutrition, that could improve quality of life (QoL) and survival in hemodialysis (HD) patients. This study set out to evaluate the effect of a personalized NIP on the nutritional status and its impact on QoL and mortality in dialyzed patients. Material and methods: this was a 12-month intervention study with regular follow-up in which nutritional parameters were measured at baseline and after 6 and 12 months. QoL was assessed by the Kidney Disease Quality of Life version 1.2 (KDQOL-SF) at baseline and at the end of the study. All dialyzed patients received individualized consultations with a trained dietitian. The content of the nutritional education program included a personalized meal plan and educational materials addressing nutrition to manage fluids, electrolytes, and vitamin D. Results: a total of 75 patients were included. After the NIP, visceral proteins, phosphorous, potassium and vitamin D levels had improved significantly (p < 0.001). The percentage of well-nourished patients increased by 30 % (p < 0.001). At the end of the study, the well-nourished patients had significantly improved scores on the general summary areas of the KDQOL-SF, reduced worry concerning fluid and dietary restrictions (p < 0.001), and the survival rate was 12 months longer (p < 0.01). Conclusion: the results of this study suggest that personalized NIP contributed to improved nutritional status, QoL and survival in HD patients.

          Resumen Objetivo: el asesoramiento dietético proporcionado a través de un programa de intervención nutricional (PIN) es recomendado por las guías clínicas renales para prevenir o tratar la desnutrición, puediendo mejorar la calidad de vida (CV) y la supervivencia en pacientes en hemodiálisis (HD). El objetivo de este estudio fue evaluar el efecto de un PNI personalizado sobre el estado nutricional y su impacto en la calidad de vida y la mortalidad en pacientes dializados. Material y métodos: estudio de intervención de 12 meses de duración, con seguimiento periódico de los pacientes en el que se midieron los parámetros nutricionales al inicio, a los 6 y 12 meses. La CV fue evaluada por el cuestionario Kidney Disease Quality of Life versión 1.2 (KDQOL-SF) al inicio y al final del estudio. Todos los pacientes dializados recibieron consultas individualizadas con un dietista. El contenido del programa de educación nutricional incluyó un plan de alimentación personalizado y materiales educativos sobre nutrición para el manejo de fluidos, electrolitos y vitamina D. Resultados: se incluyeron un total de 75 pacientes. Después del PIN, los niveles de proteínas viscerales, fósforo, potasio y vitamina D habían mejorado significativamente (p < 0,001). El porcentaje de pacientes bien nutridos aumentó un 30 % (p < 0,001). Al final del estudio, los pacientes bien nutridos mejoraron significativamente las puntuaciones en las áreas de resumen general del KDQOL-SF, redujeron la preocupación por las restricciones dietéticas y de líquidos (p < 0,001) y la tasa de supervivencia fue de 12 meses superior (p < 0,01). Conclusión: los resultados de este estudio sugieren que el PIN personalizado contribuyó a mejorar el estado nutricional, la calidad de vida y la supervivencia en pacientes en HD.

          KDOQI Clinical Practice Guideline for Nutrition in CKD: 2020 Update

          The National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) has provided evidence-based guidelines for nutrition in kidney diseases since 1999. Since the publication of the first KDOQI nutrition guideline, there has been a great accumulation of new evidence regarding the management of nutritional aspects of kidney disease and sophistication in the guidelines process. The 2020 update to the KDOQI Clinical Practice Guideline for Nutrition in CKD was developed as a joint effort with the Academy of Nutrition and Dietetics (Academy). It provides comprehensive up-to-date information on the understanding and care of patients with chronic kidney disease (CKD), especially in terms of their metabolic and nutritional milieu for the practicing clinician and allied health care workers. The guideline was expanded to include not only patients with end-stage kidney disease or advanced CKD, but also patients with stages 1-5 CKD who are not receiving dialysis and patients with a functional kidney transplant. The updated guideline statements focus on 6 primary areas: nutritional assessment, medical nutrition therapy (MNT), dietary protein and energy intake, nutritional supplementation, micronutrients, and electrolytes. The guidelines primarily cover dietary management rather than all possible nutritional interventions. The evidence data and guideline statements were evaluated using Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria. As applicable, each guideline statement is accompanied by rationale/background information, a detailed justification, monitoring and evaluation guidance, implementation considerations, special discussions, and recommendations for future research.

              Vitamin D status and mortality risk in CKD: a meta-analysis of prospective studies.

              Vitamin D deficiency, assessed as low 25-hydroxyvitamin D (25[OH]D) level, is highly prevalent in patients with chronic kidney disease (CKD) and is associated with various adverse health outcomes. Whether low 25(OH)D levels in patients with CKD are an independent risk factor for mortality remains to be studied in detail, and this was the objective of our work. A systematic review and meta-analysis of prospective observational studies. Patients with CKD. CKD was diagnosed mainly as decreased estimated glomerular filtration rate. We performed a systematic literature search in MEDLINE, ISI, and EMBASE to identify prospective studies reporting on 25(OH)D levels and mortality. 25(OH)D serum concentrations. All-cause mortality. 10 studies with an overall sample of 6,853 patients with CKD were included. Relative risk of mortality per 10-ng/mL (25-nmol/L) increase in 25(OH)D level was 0.86 (95% CI, 0.82-0.91), with no indication of publication bias or significant heterogeneity (I(2) =15%; P = 0.3). Summary estimates for CKD cohorts with and without dialysis treatment showed homogeneous results (P = 0.9). Results may be limited by heterogeneity, unconsidered confounders, and the observational design of the studies. Furthermore, publication bias by unpublished null findings on the association of 25(OH)D level and mortality cannot be ruled out and ascertainment of CKD was based largely on estimated glomerular filtration rate. Higher 25(OH)D levels are associated with significantly improved survival in patients with CKD. Whether treatment of low 25(OH)D level using natural vitamin D supplementation improves survival in patients with CKD remains to be elucidated in randomized controlled trials.
