Does intradialytic oral nutrition impact hemodialysis patients' quality of life, appetite, and safety? a pilot study of a crossover clinical trial / ¿La nutrición oral intradialítica impacta en la calidad de vida, el apetito y la seguridadde los pacientes en hemodiálisis? Estudio piloto de un ensayo clínico cruzado

Introduction: due to the catabolic characteristics of hemodialysis (HD), patients should consume foods or supplements during this treatment to meet their energy requirements and maintain a neutral nitrogen balance; however, there are some outcomes in which the effect of intradialytic oral nutrition (ION) is scarcely known. Objectives: this study aims to evaluate the effect of two types of ION (liquid and solid) on Quality of Life (QoL), appetite, and safety in HD patients. Methods: a pilot randomized, crossover clinical trial was performed in 18 patients on chronic HD. One group received ION for 18 HD sessions, after the crossover continued for 18 more sessions in the control group, and vice versa. We recorded QoL, appetite, systolic blood pressure (SBP), and intradialytic hypotension (IH) events. Results: clinical improvement was observed for most QoL components. Regardless of the consistency of supplementation, SBP increased to 4.10 mmHg. Both study groups reported a “very good-to-good” appetite. Conclusion: favorable clinical changes were observed in QoL scores during the study. Five of six IH events were reported for patients in the ION group, and SBP increased within the safe range (≤ 10 mmHg); appetite remained stable in both groups. Therefore, we concluded that this strategy, regardless of implementation consistency, is safe to be used in stable patients.(AU)

Introducción: debido a las características catabólicas de la hemodiálisis (HD), los pacientes deben consumir alimentos o suplementos durante este tratamiento para cubrir sus requerimientos energéticos y mantener un balance nitrogenado neutro; sin embargo, existen algunos desenlaces en los que el efecto de la nutrición oral intradialítica (NOID) es poco conocido.Objetivo: este estudio tiene como objetivo evaluar el efecto de dos tipos de NOID (líquido y sólido) sobre la calidad de vida, el apetito y la seguridad en pacientes en HD. Métodos: se realizó un estudio piloto en forma de ensayo clínico aleatorizado y cruzado con 18 pacientes en HD crónica. Un grupo recibió NOID durante 18 sesiones de HD, después del cruzamiento continuaron durante 18 sesiones más en el grupo de control, y viceversa. Se registraron la calidad de vida, el apetito, la presión arterial sistólica (PAS) y la hipotensión intradialítica (HI).Resultados: se observó mejoría clínica en la mayoría de los componentes de la calidad de vida. Independientemente de la consistencia de la suplementación, la PAS aumentó hasta 4,10 mmHg. Ambos grupos de estudio informaron de un apetito "muy bueno-bueno". Conclusiones: se observaron cambios clínicos favorables en las puntuaciones de calidad de vida durante el estudio. Cinco de seis eventos de HI se reportaron en pacientes del grupo de NOID y la PAS aumentó dentro del rango seguro (≤ 10 mmHg); el apetito se mantuvo estable en ambos grupos. Por lo tanto, se puede concluir que esta estrategia, independientemente de la consistencia implementada, es segura para ser utilizada en pacientes estables.(AU)

Is intradialytic oral nutritional supplementation safe and effective on clinical outcomes? A systematic review with conventional meta-analysis and network meta-analysis.

AIM: determine the effect of intradialytic oral nutrition (ION) on clinical and safety outcomes. DESIGN: Systematic Review with conventional Meta-analysis, and a Network Meta-analysis (NMA) as sensitivity analysis. We searched on MEDLINE, LILACS, CENTRAL, and EMBASE in June 2020, and the last update was until August 2022. We selected observational and randomized controlled trials with ION for at least four weeks. Primary outcomes were all-cause mortality and quality of life (QoL); adverse events, physical performance, and appetite were secondary outcomes. RESULTS: Seven clinical trials and three observational studies were selected. Even when we did not obtain significant differences in physical performance and gastrointestinal symptoms, we identified a clinical improvement in the QoL's physical role, bodily pain, and physical performance domains. After pooling the data on mortality, a protection rate trend was observed in the ION group without statistical significance. The home-prepared ION was the best nutritional supplementation when assessing the appetite outcome through NMA. CONCLUSIONS: ION seems to have a protective trend in mortality risk; the current evidence is insufficient to establish a relationship with adverse events or other clinical outcomes. The lack of homogeneity in the trials makes it difficult to generalize these results. PROSPERO REGISTRATION: CRD42020186311.

SURVEY ON THE PERCEPTION OF HEALTH PROFESSIONALS ON THE USE OF INTRADIALYTIC ORAL NUTRITION IN PATIENTS UNDER HEMODIALYSIS.

BACKGROUND: Intradialytic oral nutrition (ION) has been shown to improve many clinical outcomes, including lowering mortality, in hemodialysis (HD) patients. Despite the benefits, ION is underused in many countries. OBJECTIVE: The objective of our study was to determine the perception of health-care professionals (HCP) in our environment of the use of ION in patients undergoing HD. METHODS: Survey applied to HCP in Mexico who worked or had worked in an HD unit in their locality. RESULTS: From 272 HCP who answered the survey, 74.3% believed that the use of ION has at least one beneficial effect; of these, the most frequently mentioned were an improvement in quality of life (QoL) (54.7%) followed by an improvement in serum albumin (37.9%) and muscle anabolism (31.6%). However, 49% consider that its use involves some risks. Of the respondents, 22% reported that their HD units allowed patients to consume food or supplements during HD sessions; the main reason given to forbid the introduction of food or supplements was the clinic's policy (41%). CONCLUSIONS: The personnel surveyed heterogeneous opinions regarding ION, but most believe that it may improve the QoL or the nutritional status of the patients. Nevertheless, the use of ION is uncommon in our country as it is against the internal regulations of most HD units.

Children tolerate intradialytic oral nutrition.

BACKGROUND: People undergoing haemodialysis (HD) often have poor nutrition, which in turn can contribute to worse outcomes. Inadequate nutrition has a particularly deleterious effect on growth and neurocognitive development, as well as mortality, in children and adolescents. Nutritional supplementation can improve outcomes but can be difficult to administer. OBJECTIVE: Determine the tolerability of intradialytic oral nutrition in children and adolescents. DESIGN: A cross-sectional quality improvement study in an outpatient paediatric HD unit. Intervention was intradialytic oral nutritional supplementation provided as protein bars and/or meals. SUBJECTS: Children and adolescents undergoing outpatient HD who were able to participate in surveys and eat by mouth. MEASUREMENTS: Adverse effects and symptoms on nurse- and patient-reported surveys, respectively. Relationships between the predictor variables and the outcomes were assessed using generalised estimating equations. RESULTS: The majority of children felt better after eating on dialysis (72%) with no adverse effects (80%). On unadjusted analyses and confirmed with generalised estimating equation modelling, children who reported being hungry felt better after eating on dialysis, despite being more likely to have adverse effects. CONCLUSION: The study demonstrates that our children and adolescents feel better after eating on HD with minimal adverse effects. The finding that hungry patients are more likely to feel better despite having a higher likelihood of an adverse effect demonstrates the tolerability of eating on HD. Intradialytic oral nutrition could be a safe and well-tolerated opportunity to provide supplemental nutrition to paediatric HD patients and improve outcomes.
