Surgical Sepsis and Organ Crosstalk: The Role of the Kidney

Abstract: Acute kidney injury (AKI) is a common complication of hospitalized patients, and clinical outcomes remain poor despite advances in renal replacement therapy. The accepted pathophysiology of AKI in the setting of sepsis has evolved from one of simple decreased renal blood flow to one that involves a more complex interaction of intra-glomerular microcirculatory vasodilation combined with the local release of inflammatory mediators and apoptosis. Evidence from pre-clinical AKI models suggests that crosstalk occur… Show more

“…It is well established that cardiac and non-cardiac acute lung injuries (ALI) are the main causes of mortality in patients with AKI (8). Although the exact pathophysiology of AKI-induced ALI remains to be elucidated, the general mechanisms underlying AKI-induced ALI are well understood, including inflammation, activation of soluble and cellular factors as well as neurohumoral and hemodynamic alterations (9).…”

“…A LRA associada à sepse demonstra prevalência de aproximadamente 43%, com taxas de mortalidade superiores a 70% para os pacientes submetidos à terapia de substituição renal (1,2,5,6) . Sendo assim, as disfunções renais, principalmente a LRA, é uma das complicações mais temíveis em pacientes com sepse, pois piora o prognóstico e aumenta substancialmente os custos do tratamento nas instituições de saúde (7) .…”

“…A princípio, a expressão de NO é benéfica e resulta em ações de relaxamento vascular e inibe a agregação plaquetária e leucocitária com aumento do fluxo sanguíneo na microcirculação renal. No entanto, o aumento excessivo na geração de NO contribui para a evolução de mecanismos patológicos, como vasodilatação periférica, disfunção miocárdica, hipotensão e baixa resposta imunológica (4,5,12) .…”
