Non-valvular atrial fibrillation in patients on peritoneal dialysis, prevalence, treatment and professionals involved.

Atrial fibrillation is the most frequent chronic arrhythmia in patients with chronic kidney disease. Oral anticoagulation with vitamin K antagonists and now direct oral anticoagulants have been and are the fundamental pillars for the prevention of thromboembolic events. However, there are no randomized clinical trials on the risk-benefit profile of oral anticoagulation in patients with chronic kidney disease stage 5 on peritoneal dialysis and there is little evidence in the literature in this population. The objective of our study was to know the prevalence, treatment and professionals involved in the management of atrial fibrillation in peritoneal dialysis patients. For this purpose, we performed a descriptive analysis through a survey sent to different peritoneal dialysis units in Spain. A total of 1,403 patients on peritoneal dialysis were included in the study, of whom 186 (13.2%) had non-valvular atrial fibrillation. In addition, the assessment of the scores of thromboembolic and bleeding risks for the indication of oral anticoagulation was mainly carried out by the cardiologist (60% of the units), as well as its prescription (cardiologist 47% or in consensus with the nephrologist 43%). In summary, patients on peritoneal dialysis have a remarkable prevalence of non-valvular atrial fibrillation. Patients frequently receive oral anticoagulation with vitamin K antagonists, as well as direct oral anticoagulants. The data obtained regarding the scores used for the assessment of thromboembolic and bleeding risk, treatment and involvement by Nephrology indicates that there is a need for training and involvement of the nephrologist in this pathology.

Impact of Remote Monitoring on Standardized Outcomes in Nephrology-Peritoneal Dialysis.

Introduction: This study aimed to evaluate the association between the use of remote patient monitoring (RPM) in patients on automated peritoneal dialysis (APD) and the Standardized Outcomes in Nephrology in peritoneal dialysis (SONG-PD) clinical outcomes. Methods: A prospective and multicenter cohort study was conducted on patients with advanced chronic kidney disease on APD, recruited at 16 Spanish Hospitals, between June 1 and December 31, 2021. Patients were divided into 2 cohorts, namely patients on APD with RPM (APD-RPM) and patients on APD without RPM. The primary endpoints were the standardized outcomes of the SONG-PD clinical outcomes: PD-associated infection, cardiovascular disease (CVD), mortality rate, technique survival, and life participation (assessed as health-related quality of life [QoL]). Propensity score matching (PSM) was used to evaluate the association of RPM exposure with the clinical outcomes. Results: A total of 232 patients were included, 176 (75.9%) in the APD-RPM group and 56 (24.1%) in the APD-without-RPM group. The mean patient follow-up time was significantly longer in the APD-RPM group than in the APD-without-RPM group (10.4 ± 2.8 vs. 9.4 ± 3.1 months, respectively; P = 0.02). In the overall study sample, the APD-RPM group was associated with a lower mortality rate (hazard ratio [HR]: 0.08; 95% confidence interval [CI]: 0.01 to 0.69; P = 0.020) and greater technique survival rate (HR: 0.25; 95% CI: 0.11 to 0.59; P = 0.001). After PSM, APD-RPM continued to be associated with better technique survival (HR: 0.23; 95% CI: 0.06 to 0.83; P = 0.024). Conclusion: The use of RPM programs in patients on APD was associated with better survival of the technique and lower mortality rates. However, after PSM, only technique survival was significant.

Fibrilación auricular no valvular en pacientes en diálisis peritoneal: prevalencia, tratamiento y profesionales implicados / Non-valvular atrial fibrillation in patients on peritoneal dialysis: prevalence, treatment and professionals involved

La fibrilación auricular (FA) es la arritmia crónica más frecuente en pacientes con enfermedad renal crónica (ERC). La anticoagulación oral con antagonistas de la vitamina K (AVK) y actualmente los anticoagulantes orales de acción directa (ACOD) han sido el pilar fundamental para la prevención de eventos tromboembólicos. Sin embargo, no existen ensayos clínicos aleatorizados de su perfil riesgo-beneficio en pacientes con ERC estadio 5 en diálisis peritoneal (DP) y son pocas las evidencias en la literatura sobre esta población. El objetivo del estudio fue conocer la prevalencia, tratamiento y profesionales implicados en el manejo de la FA en DP en nuestro entorno mediante el análisis descriptivo de una encuesta enviada a diferentes unidades de DP de España. Se incluyeron en el estudio 1.403 pacientes en programa de DP, de los cuales 186 (13,2%) presentaban FA no valvular (FANV). Además, observamos que la valoración de los scores para el inicio del tratamiento anticoagulante la realizaba mayoritariamente el cardiólogo (60% de los centros), así como la prescripción de anticoagulación (cardiólogo 47% o en conjunto con el nefrólogo 43%). En conclusión, los pacientes en DP presentan una notable prevalencia de FANV. Reciben frecuentemente anticoagulación oral (ACO) con AVK, así como con ACOD. Los datos obtenidos respecto a las escalas utilizadas para la valoración de riesgo tromboembólico y de sangrado, tratamiento e implicación por parte de Nefrología indican que existe una necesidad de formación e involucramiento del nefrólogo en esta patología.(AU)

Tratamiento de la insuficiencia cardiaca en el paciente con insuficiencia renal avanzada / Heart failure therapy in patients with advanced kidney failure

La disfunción renal es común en pacientes con insuficiencia cardiaca (IC) que aumenta a medida que disminuye el filtrado glomerular estimado. Además, tiene implicaciones en el pronóstico del paciente con IC. Las recomendaciones de tratamiento de pacientes con IC y enfermedad renal crónica (ERC) concomitante no difieren, en general, de las de los pacientes con función renal normal. Pero los pacientes con enfermedad renal moderada o grave han sido excluidos de la mayoría de los ensayos clínicos, y faltan evidencia y seguridad en los tratamientos que aplicar a estos pacientes. En este artículo se analizan las evidencias existentes de los diferentes tratamientos de la IC en pacientes con ERC moderada o grave, incluidas las terapias con ultrafiltración mediante diálisis peritoneal, así como complicaciones del tratamiento como la hiperpotasemia y el deterioro en la función renal. Los inhibidores duales de la neprilisina y angiotensina parecen un tratamiento prometedor que podría reducir el riesgo de IC con seguridad entre los pacientes con ERC. El beneficio podría estar mediado, entre otros, por sus efectos renales. Otros tratamientos como los inhibidores del cotransportador de sodio-glucosa tipo 2 han mostrado beneficio en la IC de pacientes diabéticos con distintos grados de función renal. Se requieren ensayos clínicos que permitan conocer las evidencias de los tratamientos de la IC y reducir con confianza el exceso de riesgo de enfermedad cardiovascular en la enfermedad renal.

Renal impairment is common in patients with heart failure (HF) and HF increases with decreasing estimated glomerular filtration. Furthermore, renal impairment has an impact on the prognosis in patients with HF. In general, recommendations for the treatment of patients with HF and concomitant chronic kidney disease (CKD) are not different from those for patients with normal renal function. However, patients with moderate- to-severe renal impairment have been excluded from most clinical trials, and evidence and safety data on the therapies to be used in such patients are scarce. In the present paper, existing evidences on currently available therapies for HF in patients with moderate-to-severe CKD, including ultrafiltration with peritoneal dialysis, are discussed. Therapy complications, such as hyperkalaemia and renal function impairment, are also described. Dual angiotensin receptor-neprilysin inhibitors appear promising as a therapy that could safely reduce the risk of HF among patients with CKD. Their benefit could be mediated, among other mechanisms, by their renal effects. Other therapies, such as sodium-glucose cotransporter-2 inhibitors, have proved beneficial in HF in diabetic patients showing various degrees of renal function. Clinical trials are needed to obtain new evidence on the therapies for heart failure and to confidently reduce the excess risk of cardiovascular disease in renal disease.

Avanzando en el manejo de la enfermedad renal crónica: resultados de la implantación de una consulta de rápida resolución / Advancing in the management of chronic kidney disease: the results of implementing a quick resolution consultation

Antecedentes: La enfermedad renal crónica (ERC) se entiende actualmente como un importante problema de salud pública global, que requiere una nueva aproximación. Objetivos: Mostrar los resultados de la implantación de una consulta de rápida resolución para el manejo de la ERC. Métodos: Se han analizado de manera retrospectiva los resultados obtenidos durante un período de seis meses, entre septiembre de 2011 y febrero de 2012. Las variables estudiadas han sido la edad de los pacientes, el origen de las propuestas, la causa de las remisiones, el destino inicial dado a estas y el destino final de los pacientes. Resultados: Un 9,61 % de las propuestas recibidas se ha remitido a Atención Primaria sin consulta presencial. Un 28,05 % de los pacientes han sido evaluados inicialmente en la consulta de alta resolución y un 62,33 % se ha citado directamente para el resto de las consultas. Del 28,05 % inicial, tras el proceso de evaluación, ajuste e información acerca de la enfermedad un 70 % ha sido remitido nuevamente a Primaria para seguimiento, y el otro 30 % se ha citado para su seguimiento en consultas. Por tanto, del total de propuestas se ha seleccionado un 70,65 % de pacientes para seguimiento por Nefrología y un 29,35 % para seguimiento por Atención Primaria. Por otro lado, se ha disminuido la demora para primeras visitas a menos de la mitad. Conclusiones: La consulta de alta resolución se ha mostrado como un instrumento eficiente en el manejo de la ERC. Su implantación ha permitido, consumiendo un mínimo de los recursos asistenciales, seleccionar para seguimiento a largo plazo a aquellos pacientes de mayor riesgo de progresión y cardiovascular pero ofreciendo también una evaluación inicial, ajuste de tratamiento e información a los que serán seguidos por Atención Primaria, y disminuir la demora en primeras visitas de manera significativa (AU)

Background: Currently, chronic kidney disease (CKD) is understood as global important public health problem, a situation which requires a new approach. Objectives: To show the results obtained after implementing a quick resolution consultation for CKD management. Methods: Results were analysed during 6 month time period. Results: A total of 9.61% of received proposals were referred to primary care without in-person visits. In addition, 28.05% of patients were initially evaluated through high resolution consults and 62.33% were directly referred to other consults. From the initial 28.05% mentioned, once evaluated, treatment adjusted and informed about the disease, 70% were referred over to primary care for monitoring and the remaining 30% were given specialist appointments. As a consequence, 70.65% of patients were selected for monitoring by nephrology from all proposals received, and 29.35% for primary care monitoring. We observed a significant decrease in the delay until the first medical appointment. Conclusions: Quick resolution consultations demonstrated to be an efficient tool for CKD management. Its implementation allowed both low consumption of health care resources, selected patients with high risk of progression cardiovascular disease for long term monitoring, and offered not only an initial evaluation and adjustment of treatment with information provided to those who would be monitored by primary care, but also diminished primary care delays significantly (AU)
