RESUMEN
Resumen Introducción: la valoración hemodinámica mediante ecocardiografía Doppler tiene importancia en la identificación de alteraciones sistólicas/diastólicas como predictor de desenlaces en el postrasplante hepático desde alteraciones cardiovasculares hasta disfunción del injerto y mortalidad. Métodos: estudio de cohorte retrospectivo. Paciente con trasplante hepático en el hospital LaCardio, en Bogotá, Colombia entre enero de 2005 y julio de 2021. Análisis de variables sociodemográficas, comorbilidades, ecocardiografía y variables intraoperatorias con desenlaces primarios como disfunción temprana del injerto, lesión renal aguda (LRA) y mortalidad durante el seguimiento. Se realizó un árbol de clasificación y regresión (CART). Resultados: se analizaron a 397 pacientes, el 54,4% eran hombres, y el 71% tenía algún grado de disfunción diastólica, hipertrofia ventricular izquierda (30,9%) con presencia de disfunción del injerto en el 8% y LRA en el 21%, y una mortalidad del 15% durante el seguimiento del estudio. En el modelo CART para desenlaces de mortalidad y disfunción del injerto se relacionó con la presencia de índice de masa corporal (IMC) < 19 o la combinación de IMC entre 19 y < 24 con diálisis. Conclusión: las variables ecocardiográficas, la sarcopenia y la LRA o requerimiento de terapia de reemplazo renal se relacionan con desenlaces de mortalidad y disfunción del injerto.
Abstract Introduction: Hemodynamic assessment by Doppler echocardiography is essential in identifying systolic/diastolic changes as a predictor of outcomes in post-liver transplantation, from cardiovascular changes to graft dysfunction and mortality. Materials and methods: Retrospective cohort study. Patient with a liver transplant at the LaCardio hospital in Bogotá, Colombia, between January 2005 and July 2021. Analysis of sociodemographic variables, comorbidities, echocardiography, and intraoperative variables with primary outcomes such as early graft dysfunction, acute kidney injury (AKI), and mortality during follow-up. A classification and regression tree (CART) was performed. Results: 397 patients were analyzed; 54.4% were men, 71% had some degree of diastolic dysfunction and left ventricular hypertrophy (30.9%) with graft dysfunction in 8% and AKI in 21%, and a mortality of 15% during the study follow-up. In the CART model, mortality and graft dysfunction outcomes were related to a body mass index (BMI) < 19 or a combination of BMI between 19 and < 24 with dialysis. Conclusion: Echocardiographic variables, sarcopenia, AKI, or the requirement for renal replacement therapy are related to mortality and graft dysfunction outcomes.
RESUMEN
Abstract Rapidly progressive glomerulonephritis is a medical emergency, with mortality around 20%. It is characterized by crescent glomerulonephritis and progressive loss of kidney function, hematuria, and proteinuria. Its classification is given by immunofluorescence detection of antibodies against glomerular basement membrane (Anti-MBG), immunocomplexes, or pauci-immune pattern. Its etiology should be based on clinical findings, immunological profile, age, sex, and histopathological characteristics. We present a case of a 27-year-old woman with symptoms consistent with rapidly progressive glomerulonephritis and biopsy findings of a full-house kidney nephropathy, with an early fatal outcome. An association of low incidence, as it is a case with a full-house pattern, and an autoimmune profile for negative systemic lupus erythematosus makes this a rare case. ANCA-associated vasculitis with full-house kidney disease was diagnosed, an unusual condition with up to 3% presentation and few reports in the literature, highlighting the importance of its reporting and contribution to the literature.
Resumo A glomerulonefrite rapidamente progressiva é uma emergência médica, com mortalidade em torno de 20%. É caracterizada por glomerulonefrite com crescentes e perda progressiva da função renal, hematúria e proteinúria. Sua classificação é dada pela detecção na imunofluorescência de anticorpos anti-membrana basal glomerular (Anti-MBG), imunocomplexos, ou padrão pauci-imune. Sua etiologia deve ser baseada em resultados clínicos, perfil imunológico, idade, sexo e características histopatológicas. Apresentamos o caso de uma mulher de 27 anos de idade com sintomas consistentes com uma glomerulonefrite rapidamente progressiva e achados de biópsia de uma nefropatia com padrão full-house que evoluiu com desfecho fatal precoce. A associação de um padrão full-house, que possui uma baixa incidência, com um perfil autoimune para lúpus eritematoso sistêmico negativo torna este um caso raro. Foi diagnosticado vasculite associada ao ANCA com doença renal com padrão full-house. Por se tratar de uma condição incomum com até 3% de apresentação e poucos registros na literatura, destacamos a importância de seu relato e sua contribuição para a literatura.
