Opportunities to improve the management of anemia in peritoneal dialysis patients: lessons from a national study in routine clinical practice.

Background: Current guidelines establish the same hemoglobin (Hb) and iron biomarkers targets for hemodialysis (HD) and peritoneal dialysis (PD) in patients receiving erythropoiesis-stimulating agents (ESAs) even though patients having PD are usually younger, more active and less comorbid. Unfortunately, specific renal anemia [anemia in chronic kidney disease (aCKD)] trials or observational studies on PD are scanty. The aims of this study were to describe current aCKD management, goals and adherence to clinical guidelines, identifying opportunities for healthcare improvement in PD patients. Methods: This was a retrospective, nationwide, multicentre study including patients from 19 PD units. The nephrologists collected baseline data, demographics, comorbidities and data related to anemia management (laboratory values, previously prescribed treatments and subsequent adjustments) from electronic medical records. The European adaptation of KDIGO guidelines was the reference for definitions, drug prescriptions and targets. Results: A total of 343 patients (mean age 62.9 years, 61.2% male) were included; 72.9% were receiving ESAs and 33.2% iron therapy [20.7% intravenously (IV)]. Eighty-two patients were receiving ESA without iron therapy, despite 53 of them having an indication according to the European Renal Best Practice guidelines. After laboratory results, iron therapy was only started in 15% of patients. Among ESA-treated patients, 51.9% had an optimal control [hemoglobin (Hb) 10-12 g/dL] and 28.3% between 12-12.9 g/dL. Seventeen patients achieved Hb >13 g/dL, and 12 of them remained on ESA after overshooting. Only three patients had Hb <10 g/dL without ESAs. Seven patients (2%) met criteria for ESA resistance (epoetin dose >300 IU/kg/week). The highest tertile of erythropoietin resistance index (>6.3 UI/kg/week/g/dL) was associated with iron deficiency and low albumin corrected by renal replacement therapy vintage and hospital admissions in the previous 3 months. Conclusion: Iron therapy continues to be underused (especially IV). Low albumin, iron deficiency and prior events explain most of the ESA hyporesponsiveness. Hb targets are titrated to/above the upper limits. Thus, several missed opportunities for adequate prescriptions and adherence to guidelines were identified.

Análisis de las infecciones del orificio de salida del catéter peritoneal. Efectividad de un protocolo basado en la aplicación de mupirocina tópica diaria / Analysis of peritoneal catheter exit-site infections. Effectiveness of a protocol based on daily topical mupirocin application

Objetivos: Analizar las infecciones del orificio de salida del catéter peritoneal, identificando los principales factores relacionados con las mismas; asimismo se ha comparado la efectividad de un protocolo basado en la utilización diaria de mupirocina tópica en la cura del orificio de salida frente a la utilización suero salino.Material y Método:Estudio observacional, retrospectivo. Recogimos variables demográficas, clínicas, la etiología y evolución de los episodios de infección del orificio en un periodo de 2 años. Utilizamos un protocolo de profilaxis con suero fisiológico y con mupirocina crema al 2%.Resultados:Estudiamos 75 pacientes, edad media 60,3±13,9 años, 66,7% varones, mediana de tiempo en diálisis peritoneal 24,3 meses (rango intercuartílico 11-48,7). La incidencia de infección del orificio de salida fue del 26,7%, el 77% fueron originadas por microorganismos de piel y mucosas. La infección del orificio de salida se relacionó con el estado portador nasal de Staphylococcus aureus (p=0,048) y la extrusión del dacron externo (p=0,004). De los 4 pacientes que presentaron una peritonitis secundaria a la infección del orificio de salida, 3 fueron trasferidos a hemodiálisis (p=0,025). Con el protocolo de antibioterapia tópica diaria se redujo un 68% la tasa de infecciones.Conclusiones:La exteriorización del anillo externo del catéter peritoneal es un factor predisponente de infecciones. La aplicación diaria de mupirocina es una estrategia efectiva para reducir la incidencia de infección del orificio y peritonitis. La erradicación de portadores nasales de Staphylococcus aureus puede contribuir a reducir la pérdida del catéter y la transferencia a hemodiálisis. (AU)

Objectives: To analyze the characteristics of catheter related exit-site infections, identifying the main related factors. Likewise, the effectiveness of a protocol based on the daily use of topical mupirocin in the exit site prophylaxis strategy has been compared with the use of saline solution.Material and Method: Observational retrospective study. Demographic and clinical variables, the etiology and evolution of the episodes of infection of the orifice in a period of 2 years were collected. A prophylaxis protocol with saline solution and 2% mupirocin cream was used.Results:We recruited 75 patients, mean age 60.3±13.9 years, 66.7% male, median time on peritoneal dialysis 24.3 months (interquartile range 11-48.7). The incidence of exit site infection was 26.7%, 77% were produced by skin and mucous microorganisms. The exit site infection was associated to Staphylococcus aureus nasal carriage (p=0.048) and the superficial cuff extrusion (p=0.004). 4 of the patients who presented peritonitis secondary to exit site infection, 3 were switch to hemodialysis (p=0.025). Daily topical antibiotic therapy protocol reduced the exit site infection rate by 68%.Conclusions:The superficial cuff externalization is a predisposing factor for infections. Daily application of mupirocin is an effective strategy in reducing the incidence of exit site infections and peritonitis. The eradication of nasal carriers of Staphylococcus aureus can help reduce catheter loss and transfer to hemodialysis. (AU)

The role of an electronic alert system to detect acute kidney injury in hospitalized patients: DETECT-H Project / Utilidad de un sistema de alerta electrónica para la detección de fracaso renal agudo en pacientes hospitalizados. Proyecto DETECT-HP

BACKGROUND AND AIMS: Acute kidney injury (AKI) is associated with higher mortality and length of stay (LOS) for hospitalized patients. To improve outcomes, an electronic detection system could be a useful tool for early diagnosis. METHODS: A fully automated real-time system for detecting decreased glomerular filtration rate in adult patients was developed in our hospital, DETECT-H project. AKI was established according to KDIGO guidelines. RESULTS: In six months, 1241 alerts from 11,022 admissions were issued. Overall incidence of AKI was 7.7%. Highest AKI stage reached was: stage 1 (49.8%), 2 (24.5%) and 3 (25.8%), in-hospital mortality was 10.9%, 22.7%, 33.9% respectively and 57.1% in AKI requiring dialysis; mortality in stable CKD was 4.3%. Median LOS was 8 days versus 5 days for all patients. AKI was associated with a mortality of 3.18 (95% CI 1.80-5.59) and a LOS 1.52 (1.11-2.08) times as high as that for admissions without AKI. Multivariate analysis indicated that a LOS higher than 8 days was associated with AKI. Previous CKD was noted in 31.9% and AKI in 45.3% at discharge. As compared to the use of the detect system, only one third of CKD patients and half of AKI episodes were identified. CONCLUSIONS: CKD and in-hospital AKI are under-recognized entities. Mortality and LOS are increased in-hospital patients with renal dysfunction. AKI severity was associated with higher mortality and LOS. An automated electronic detection system for identifying renal dysfunction would be a useful tool to improve renal outcomes

INTRODUCCIÓN Y OBJETIVOS: El fracaso renal agudo (FRA) aumenta la mortalidad y la estancia hospitalarias (EH). El empleo de sistemas de detección electrónica podría ser una herramienta beneficiosa para mejorar estos resultados. MÉTODOS: Se desarrolló un sistema de detección automático a tiempo real de pacientes ingresados con función renal alterada, denominado proyecto DETECT-H. El FRA se estableció de acuerdo con las guías KDIGO. RESULTADOS: En 6 meses, 1.241 alertas fueron recogidas de 11.022 ingresos. La incidencia global del FRA fue del 7,7%. La distribución en función del estadio máximo del FRA alcanzado fue: estadio 1: 49,8%, estadio 2: 24,5% y estadio 3: 25,8%; con una mortalidad hospitalaria del 10,9, 22,7 y 33,9%, respectivamente. En el caso del FRA con necesidad de diálisis fue del 57,1%. La mortalidad en pacientes con enfermedad renal crónica (ERC) estable fue del 4,3%. La mediana de EH en pacientes detectados fue 8 vs. 5 días para todos los pacientes hospitalizados. El FRA se asoció con una mortalidad 3,18 (1,8-5,59) y una EH 1,52 (1,11-2,08) veces superior que aquellos ingresos sin FRA. El análisis multivariante indicó que el FRA se asociaba con la EH > 8 días. En los informes de alta, la presencia de ERC previa solo fue registrada en el 31,9% de los pacientes con ERC y el FRA hospitalario en el 45,3%. Conclusiones : La ERC y el FRA intrahospitalario son entidades infradiagnosticadas. La mortalidad y la EH están aumentadas en pacientes con disfunción renal. La gravedad del FRA se asoció con mayor mortalidad y EH. Un sistema de detección automático para identificarlos podría ser útil para mejorar estos resultados
