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.

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)

Silent challenge: Early kidney transplant failure and cardiomyopathy.

Differentiation of hypertrophic cardiomyopathy phenotypes is challenging but crucial for appropriate management. We report a case of myocardial oxalate deposition as an infrequent cause of infiltrative cardiomyopathy.
