Fallo renal agudo en unidades críticas. Factores de riesgo y mortalidad / Acute kidney injury care units. Risk factors and mortality

INTRODUCCIÓN: El fallo renal agudo (FRA) es una complicación muy frecuente en pacientes críticos, y se asocia con una elevada morbimortalidad. Objetivos: Los objetivos de este estudio fueron analizar la incidencia, factores de riesgo y mortalidad asociados a FRA en pacientes críticos; así como determinar la incidencia de requerimiento de TRR (terapias de reemplazo renal). MATERIAL Y MÉTODOS: Se realizó un estudio de cohorte prospectivo y observacional. Se incluyeron todos los pacientes que ingresaron en unidades críticas del Hospital Privado Universitario de Córdoba, entre enero y marzo de 2016. Se realizó un seguimiento de 7 días. RESULTADOS: Se incluyeron 150 pacientes. La incidencia de FRA fue del 44.7% (n=67). El 70.1% (n=47) fueron de origen pre-renal. Mientras que el 73.1% (n=49) ingresaron por alguna patología médica. Los factores de riesgo de FRA hallados en el análisis multivariado fueron la enfermedad renal crónica (ERC) y el score SOFA elevado. Ajustado por las demás variables, los sujetos con ERC tuvieron cuatro veces más posibilidades de tener FRA (OR ajustado=4.76, IC95%=1.93-11.75, p=0.001), mientras que por cada un punto de incremento del SOFA, el riesgo aumentó un 25% (OR ajustado=1.25, IC95%=1.08-1.44, p=0.003). Las variables de mortalidad halladas en el mismo análisis fueron el uso de vasopresores y el FRA. Los sujetos con FRA tuvieron seis veces mayor riesgo de mortalidad en el tiempo (HR ajustado=6.33, IC95%=1.41-28.4, p=0.016). CONCLUSIÓN: La presencia de ERC y el valor del SOFA elevados fueron los factores de riesgo que influyeron en la aparición de FRA, mientras que el FRA fue un factor de riesgo independiente de mortalidad a corto plazo

INTRODUCTION: Acute kidney injury (AKI) is a very common complication among patients in critical conditions and it is associated with a high morbidity and mortality rate. OBJECTIVES: The aims of this study were the following: analyze the incidence, risk factors and mortality related to AKI in patients in critical conditions, as well as to determine the incidence of RRT (renal replacement therapy) requirement. METHODS: A prospective cohort observational study was performed. Patients admitted to the intensive care units of the Hospital Privado Universitario de Córdoba (Private Medical College Hospital of Córdoba) in 2016, between January and March, were included. A 7-day follow-up was conducted. RESULTS: There were 150 patients included in this study. Incidence of AKI was of 44.7% (n=67). Causes of AKI were prerenal in 70.1% (n=47) of cases; whereas 73.1% (n=49) of patients were admitted due to some pathology. Risk factors for AKI found through multivariate analysis were Chronic Kidney Disease (CKD) and a high SOFA score. Adjusted for other variables, patients with CKD are four times more likely to suffer from AKI (adjusted OR= 4.76; 95% CI= 1.93-11.75; p=0.001), whereas for each additional point in the SOFA score, risk was 25% higher (adjusted OR=1.25; 95% CI=1.08-1.44; p=0.003). The same analysis showed that the mortality variables were the use of vasopressors and AKI. AKI patients had a mortality risk six times higher over time (adjusted HR=6.33; 95% CI= 1.41-28.4, p=0.016). CONCLUSION: Presence of CKD and a high SOFA score were the risk factors which triggered AKI, whereas AKI was an independent risk factor for short-term mortality

For patients with chronic renal failure (CRF), kidney transplant (KT) is a better alternative to dialysis in terms of survival, life quality and costs. We studied the general characteristics, causes and survival rate of the dialysis population in 2010. We evaluated broader criteria for acceptance of transplants has affected the results of the procedure in that period. A total of 118 dialysis patients were included; mean age 56.9 ± 18.4 years, dialysis duration 45.5 ± 59.6 months, main cause of CRF was diabetes in 35 (30%), and 58 (49%) were included in waiting list for KT. Of the 34 patients who finished dialysis in 2010, 18 (53%) were KT, while 12 (35%) died (cardiovascular 50%, infectious 17%). Survival at 12 months was 85% for the total group, 98% on waiting list and 72% those who were not enrolled. During 2010 there were 88 KT, 62 with cadaveric donors (CD), 18 with living donors and 8 with double pancreas-kidney transplants. Recipients of CD were 50.7 years old, with 67 months on dialysis, 8 (13%) diabetics, and 12 (20%) with previous KT. Donors had a mean age of 45 years, 28 (45%) expanded criteria, and 27.7 hours of cold ischemia time. During an approximate follow-up of 11.4 months, 13 (21%) suffered acute graft rejection, survival was 88% for graft and 93% for patients. We emphasize KT as the main cause of success as regards dialysis. No differences in risk factors were found to significantly affect graft or patient survival.

El trasplante renal (TR) presenta mejor supervivencia, calidad de vida y costos que la diálisis en la insuficiencia renal crónica (IRC). Estudiamos pacientes en diálisis que recibieron TR durante 2010, las causas de finalización del tratamiento y la supervivencia en diálisis. Evaluamos si criterios más amplios para la aceptación de trasplantes hubieran afectado los resultados del procedimiento en ese período. Incluimos 118 pacientes en diálisis, edad media 56.9 ± 18.4 años, tiempo en diálisis 45.5 ± 59.6 meses, 35 (30%) presentaban diabetes como causa de IRC, y 58 (49%) estaban en espera del TR. Treinta y cuatro finalizaron diálisis, 18 por TR y 12 por fallecimiento. Las principales causas de muerte fueron cardiovasculares, 6 (50%) e infecciones, 2 (17%). La supervivencia al año fue 85% para el grupo total, 98% para los pacientes inscriptos en lista de espera y 72% para no inscriptos. Durante 2010 se realizaron 88 TR (62 con donantes cadavéricos [DC], 18 donantes vivos y 8 dobles trasplantes páncreas-riñón). Los receptores de DC tenían en promedio 50.7 años, 67 meses en diálisis, 8 (13%) eran diabéticos, 12 (20%) con TR previos y 3 cross match contra panel de anticuerpos > 20%. Los donantes tenían edad media 45 años, 28 (45%) con criterios expandidos y 27.7 h de isquemia fría. A los 11.4 meses de seguimiento, 13 (21%) presentó rechazo agudo, la supervivencia para injerto fue de 88% y 93% para pacientes. La principal causa de finalización de diálisis fue TR, sin detectarse que el empleo de DC afectara la supervivencia del TR.
