RESUMO
Background: Dialysis patients have been maintaining a high rate of cardiovascular morbidity and mortality. For this reason, it is to introduce necessary new technical advances in clinical practice. There is a relation between toxins retention and inflammation, mortality and morbidity. Medium cut-off (MCO) membranes are a new generation of membranes that allow the removal of a greater number of medium-sized molecules compared with high-flux hemodialysis (HF-HD), but retaining albumin. MCO membranes have an increased permeability and the presence of internal filtration. Because of these special properties, MCO generated a new concept of therapy called expanded HD (HDx). Until now, online hemodiafiltration (OL-HDF) has demonstrated its superiority, in terms of survival, compared with HF-HD. However, the comparison between OL-HDF and HDx remains an unsolved question. Methods: The MOTheR HDx study trial (NCT03714386) is an open-label, multicenter, prospective, 1:1 randomized, parallel-group trial designed to evaluate the efficacy and safety of HDx compared with OL-HDF in patients treated for dialysis in Spain for up to 36 months. The main endpoint is to determinate whether HDx is non inferior to OL-HDF at reducing the combined outcome of all-cause death and stroke (ischemic or hemorrhagic), acute coronary syndrome (angina and myocardial infarction), peripheral arterial disease (amputation or revascularization) and ischemic colitis (mesenteric thrombosis). Results: The trial has already started.
RESUMO
La ecografía es una herramienta esencial en el manejo del paciente nefrológico que permite el diagnóstico, el seguimiento y la realización de intervencionismo sobre el riñón. La utilidad de los ultrasonidos en Nefrología no se circunscribe exclusivamente al estudio ecográfico del riñón. Mediante ecografía el nefrólogo puede, además, optimizar el manejo de la fístula arteriovenosa para hemodiálisis, medir el riesgo cardiovascular (grosor íntima-media), implantar catéteres centrales para hemodiálisis ecoguiados y ayudar en la colocación de los peritoneales, así como calcular la volemia del paciente mediante ecografía cardiaca básica, ecografía de la vena cava inferior y pulmonar. Desde el Grupo de Trabajo en Nefrología Diagnóstica e Intervencionista (GNDI) de la Sociedad Española de Nefrología (SEN) hemos elaborado este documento de consenso en el que se resumen las principales aplicaciones de la ecografía en Nefrología, incluyendo los requisitos técnicos básicos necesarios, el marco normativo y el nivel de capacitación de los nefrólogos en esta materia. El objetivo de este trabajo es promover la inclusión de la ecografía, tanto diagnóstica como intervencionista, en la práctica clínica habitual del nefrólogo y en la cartera de servicios de Nefrología con la finalidad de ofrecer un manejo diligente, eficiente e integral al paciente nefrológico
Ultrasound is an essential tool in the management of the nephrological patient allowing the diagnosis, monitoring and performance of kidney intervention. However, the usefulness of ultrasound in the hands of the nephrologist is not limited exclusively to the ultrasound study of the kidney. By ultrasound, the nephrologist can also optimize the management of arteriovenous fistula for hemodialysis, measure cardiovascular risk (mean intimate thickness), implant central catheters for ultrasound-guided HD, as well as the patient's volemia using basic cardiac ultrasound, ultrasound of the cava inferior vein and lungs. From the Working Group on Interventional Nephrology (GNDI) of the Spanish Society of Nephrology (SEN) we have prepared this consensus document that summarizes the main applications of ultrasound to Nephrology, including the necessary basic technical requirements, the framework normative and the level of training of nephrologists in this area. The objective of this work is to promote the inclusion of ultrasound, both diagnostic and interventional, in the usual clinical practice of the nephrologist and in the Nephrology Services portfolio with the final objective of offering diligent, efficient and comprehensive management to the nephrological patient
