Personalized peritoneal dialysis prescription-beyond clinical or analytical values.

Traditionally, dialysis adequacy has been assessed primarily by determining the clearance of a single small solute, urea. Nevertheless, it has become increasingly evident that numerous other factors play a crucial role in the overall well-being, outcomes and quality of life of dialysis patients. Consequently, in recent years, there has been a notable paradigm shift in guidelines and recommendations regarding dialysis adequacy. This shift represents a departure from a narrow focus only on the removal of specific toxins, embracing a more holistic, person-centered approach. This new perspective underscores the critical importance of improving the well-being of individuals undergoing dialysis while simultaneously minimizing the overall treatment burden. It is based on a double focus on both clinical outcomes and a comprehensive patient experience. To achieve this, a person-centered approach must be embraced when devising care strategies for each individual. This requires a close collaboration between the healthcare team and the patient, facilitating an in-depth understanding of the patient's unique goals, priorities and preferences while striving for the highest quality of care during treatment. The aim of this publication is to address the existing evidence on this all-encompassing approach to treatment care for patients undergoing peritoneal dialysis and provide a concise overview to promote a deeper understanding of this person-centered approach.

Experiencia en España con los primeros pacientes en hemodiálisis domiciliaria tratados con monitores de bajo flujo de líquido de diálisis / Experience in Spain with the first patients in home hemodialysis treated with low-flow dialysate monitors

La hemodiálisis domiciliaria (HDD) con monitores de bajo flujo de líquido de diálisis ha ganado popularidad en los últimos años gracias a su sencillez de diseño, portabilidad y capacidad de desplazamiento. No obstante, existen dudas respecto a la adecuación que este tipo de técnica ofrece, pues utiliza monitores con baño a flujos bajos y lactato. El objetivo de este estudio fue demostrar los beneficios clínicos de la HDD con el monitor NxStage System One® introducido recientemente en España.Presentamos los resultados de un estudio observacional, retrospectivo que incluyó de manera no seleccionada a los primeros pacientes con HDD corta mediante este monitor en 12 centros en España. Se analizó la evolución clínica de 86 pacientes a 0, 6 y 12 meses, incluyendo datos relacionados con la prescripción, evolución de parámetros analíticos de dosis de diálisis, anemia, metabolismo óseo-mineral, evolución de la diuresis residual, utilización de fármacos y datos relacionados con permanencia en la técnica, y causas de salida a lo largo del seguimiento. Pudimos demostrar que este monitor proporcionó una adecuada dosis de diálisis, con tasa óptima de ultrafiltración, con mejoría de los principales marcadores bioquímicos de adecuación en diálisis. El uso de esta técnica se asoció con una disminución de antihipertensivos, captores del fósforo y agentes eritropoyéticos, observándose, además, muy buenos resultados de supervivencia tanto del paciente como de la técnica. La sencillez de este monitor unida a sus buenos resultados clínicos debería facilitar el crecimiento y utilización de la HDD, tanto en pacientes incidentes como prevalentes. (AU)

Home hemodialysis (HHD) with low-flow dialysate devices has gained popularity in recent years due to its simple design, portability, and ability to provide greater freedom of movement for our patients. However, there are doubts about the adequacy that this technology offers, since it uses monitors with low-flow bath and lactate. The aim of this study was to demonstrate the clinical benefits of low-flow HHD with the NxStage System One® recently introduced in Spain. We present the results of an observational, retrospective cohort study that included the first patients who started short daily HHD with this device in 12 Spanish centers. We analyzed the evolution of 86 patients at 0, 6 and 12 months, including data related to prescription, and evolution of biochemical parameters related to dialysis dose, anemia, mineral-bone metabolism; evolution of residual renal function, medication usage, and causes of withdrawal during the followup. We were able to demonstrate that this NxStage System One® monitor, in patients with HHD, have provided an adequate dialysis dose, with optimal ultrafiltration rate, with improvement of main biochemical markers of dialysis adequacy. The usage of this technique was associated to a decrease of antihypertensive drugs, phosphate binders and erythropoietin agents, with very good results both patient and technique survival. The simplicity of the technique, together with its good clinical outcomes, should facilitate the growth and utilization of HHD, both in incident and prevalent patients. (AU)

Integrated care: enhancing transition from renal replacement therapy options to home haemodialysis.

Transition is an intrinsic process in the life of a patient with kidney disease and should be planned and anticipated when possible. A single therapy option might not be adequate across a patient's entire lifespan and many patients will require a switch in their treatment modality to adapt the treatment to their clinical and psychosocial needs. There are several reasons behind changing a patient's treatment modality, and the consequences of each decision should be evaluated, considering both short- and long-term benefits and risks. Dialysis modality transition is not only to allow for technical optimization or improved patient survival, the patient's experience associated with the transition should also be taken into account. Transition should not be considered as treatment failure, but rather as an expected progression in the patient's treatment options.

Low Serum Levels of Vitamin D are Associated with Progression of Subclinical Atherosclerotic Vascular Disease in Peritoneal Dialysis Patients: A Prospective, Multicenter Study.

BACKGROUND: The prevalence of subclinical atherosclerosis and the main predictors of progression of this condition in patients undergoing peritoneal dialysis (PD) have been insufficiently investigated. OBJECTIVES AND METHOD: Following a prospective, multicenter, observational design, we studied 237 patients who were treated with PD for ≥3 months, without any clinical background of cardiovascular (CV) disease. Our objectives were the following: (1) to investigate the prevalence of subclinical atherosclerosis, as compared to a control group of age- and sex-matched healthy individuals, and (2) to disclose PD technique-related predictors of progression of disease during a 24-month follow-up period. We used vascular ultrasound for characterization of subclinical atherosclerotic disease. MAIN RESULTS: A total of 123 patients (51.9%) vs. 79 controls (33.5%) presented ≥1 carotid plaque, and 114 patients (48.3%) vs. 72 controls (30.5%) ≥1 femoral plaque, at baseline evaluation (p < 0.0005). Progression of disease, either in clinical or ultrasound (new plaques) terms, affected 62.6% of patients. Multivariate analysis identified age, carotid intima-media thickness, presence of ≥1 carotid plaque, and serum levels of 25OH vitamin D and C-reactive protein (CRP) at baseline as independent correlates of progression of atherosclerotic disease. On the contrary, PD technique-related variables did not show any association with this outcome. CONCLUSIONS: Atherosclerotic vascular disease is frequent among asymptomatic patients undergoing PD. Older age, pre-existent disease (assessed by vascular ultrasound), and serum levels of 25OH vitamin D and CRP are independent markers of the progression of this condition. These findings may contribute to improve identification of subpopulations with a high risk of CV events, deserving intensified measures of prevention.
