Resumen
A pesar de los avances en el desarrollo de las terapias de reemplazo renal, la mortalidad de la falla renal aguda permanece elevada, especialmente, cuando se manifiesta simultáneamente con fallas orgánicas distantes, como es en el caso del síndrome de distrés respiratorio agudo. Se revisa la relación bidireccional deletérea entre pulmón y riñón, en el escenario de disfunción orgánica, la cual presenta aspectos clínicos relevantes de conocer. Se discuten los efectos renales del síndrome de distrés respiratorio agudo y del uso de la ventilación mecánica a presión positiva, siendo el daño inducido por este (ventilator induced lung injury) uno de los modelos utilizado frecuentemente para el estudio de la interacción pulmón-riñón. Se enfatiza el rol de la falla renal inducida por la ventilación mecánica (ventilator-induced kidney injury) en la patogenia de la falla renal aguda. Asimismo se analizan las repercusiones pulmonares de la falla renal aguda, reconociéndose que esta condición patológica induce un incremento en la permeabilidad vascular pulmonar, inflamación y alteración de los canales de sodio y agua del epitelio alveolar, entre otros efectos. Este modelo conceptual puede ser la base para el desarrollo de nuevas estrategias terapéuticas a utilizar en el paciente con síndrome de disfunción orgánica múltiple.
Despite advances in the development of renal replacement therapy, mortality of acute renal failure remains high, especially when occurring simultaneously with distant organic failure as it is in the case of the acute respiratory distress syndrome. In this update, birideccional deleterious relationship between lung and kidney on the setting of organ dysfunction is reviewed, which presents important clinical aspects of knowing. Specifically, the renal effects of acute respiratory distress syndrome and the use of positive-pressure mechanical ventilation are discussed, being ventilator induced lung injury one of the most common models for studying the lung-kidney crosstalk. The role of renal failure induced by mechanical ventilation (ventilator-induced kidney injury) in the pathogenesis of acute renal failure is emphasized. We also analyze the impact of the acute renal failure in the lung, recognizing an increase in pulmonary vascular permeability, inflammation, and alteration of sodium and water channels in the alveolar epithelial. This conceptual model can be the basis for the development of new therapeutic strategies to use in patients with multiple organ dysfunction syndrome.
