AKI organ cross talk

Maryam Malek, Jalal Hassanshahi, Reza Fartootzadeh, Fatemeh Azizi, Somayeh Shahidani
The kidneys have a close functional relationship with other organs especially the lungs. This connection makes the kidney and the lungs as the most organs involved in the multi-organ failure syndrome. The combination of acute lung injury (ALI) and renal failure results a great clinical significance of 80% mortality rate. Acute kidney injury (AKI) leads to an increase in circulating cytokines, chemokines, activated innate immune cells and diffuse of these agents to other organs such as the lungs. These factors initiate pathological cascade that ultimately leads to ALI and acute respiratory distress syndrome (ARDS)...

BACKGROUND: Acute kidney injury (AKI) is one of the most common complications in acutely ill patients. The epidemiology, clinical presentation, and outcome vary between patients and countries. SUMMARY: Patients with AKI often exhibit multiple organ dysfunction that is caused, in part, by marked cross-talk between the kidney and other organs and tissues. These deleterious interactions arise, at least in part, from systemic inflammatory changes, an increased cytokine load, increases in leukocyte trafficking and activation of neurohormonal processes...

Cardiovascular disease and major cardiovascular events represent main cause of death in both acute and chronic kidney disease patients. Kidney and heart failure are common and frequently co-exist; this organ - organ interaction, also called organ cross-talk led to well-known definition of cardiorenal syndrome (CRS). Here we'll describe cardiovascular involvement in patients with acute kidney injury (AKI). Also known as type-3 CRS or acute reno-cardiac CRS, it occurs when AKI contributes and/or precipitates development of acute cardiac injury...

Acute kidney injury (AKI) is the most common cause of organ dysfunction in critically ill adults, with a single episode of AKI, regardless of stage, carrying a significant morbidity and mortality risk. Since the consensus on AKI nomenclature has been reached, data reflecting outcomes have become more apparent allowing investigation of both short- and long-term outcomes.Classically the short-term effects of AKI can be thought of as those reflecting an acute deterioration in renal function per se. However, the effects of AKI, especially with regard to distant organ function ("organ cross-talk"), are being elucidated as is the increased susceptibility to other conditions...

Acute kidney injury (AKI) is a common complication in critically ill patients and subsequently worsens outcomes. Although many drugs to prevent and treat AKI have shown benefits in preclinical models, no specific agent has been shown to benefit AKI in humans. Moreover, despite remarkable advances in dialysis techniques that enable management of AKI in hemodynamically unstable patients with shock, dialysis-requiring severe AKI is still associated with an unacceptably high mortality rate. Thus, focusing only on kidney damage and loss of renal function has not been sufficient to improve outcomes of patients with AKI...

Acute kidney injury (AKI) is a common and serious condition with no specific treatment. An episode of AKI may affect organs distant from the kidney, further increasing the morbidity associated with AKI. The mechanism of organ cross talk after AKI is unclear. The renal and immune systems of pigs and humans are alike. Using a preclinical animal (porcine) model, we tested the hypothesis that early effects of AKI on distant organs is by immune cell infiltration, leading to inflammatory cytokine production, extravasation, and edema...

The pathophysiology of acute kidney injury (AKI) involves multiple and overlapping immunological, biochemical, and hemodynamic mechanisms that modulate the effects of both the initial insult and the subsequent repair. Limited but recent experimental data have revealed that the intestinal microbiota significantly affects outcomes in AKI. Additional evidence shows significant changes in the intestinal microbiota in chronic kidney disease patients and in experimental AKI. In this minireview, we discuss the current status of the effect of intestinal microbiota on kidney diseases, the immunomodulatory effects of intestinal microbiota, and the potential mechanisms by which microbiota can modify kidney diseases and vice versa...

Increasing evidence suggests that acute kidney injury (AKI) mediates a systemic response that can lead to multiple organ failure. AKI may manifest in a variety of clinical scenarios including kidney transplantation and is associated with a significantly high mortality. It has been postulated that specific pro-inflammatory cytokines, including IL-1β, IL-6, and TNF-α, may mediate a systemic response, resulting in recruitment of pro-inflammatory cells leading to organ failure. However, the specific mechanism by which the cytokine cascade results in distant organ damage is yet to be determined...

Following the induction of ischemic or toxin-mediated acute kidney injury (AKI), cellular adaptations occur that 're-program' how the kidney responds to future superimposed insults. This re-programming is not simply a short-lived phenomenon; rather it can persist for many weeks, implying that a state of 'biologic memory' has emerged. These changes can be both adaptive and maladaptive in nature and they can co-exist in time. A beneficial adaptation is the emergence of acquired cytoresistance, whereby a number of physiologic responses develop that serve to protect the kidney against further ischemic or nephrotoxic attack...

Acute injuries of the kidney or lung each represent serious, complex clinical problems, and their combination drastically decreases patient survival. However, detailed understanding of interactions between these two organs is scarce. To evaluate this further, we used the folic acid (FA) and myohemoglobinuria models of acute kidney injury (AKI) together with Pseudomonas aeruginosa inhalation to study kidney-lung cross-talk in mice during acute kidney and lung injury. Subgroups of mice received antineutrophil antibody or platelet-depleting serum to assess the role of neutrophil and platelets, respectively...

Acute lung injury (ALI) and acute kidney injury (AKI) are complications often encountered in the setting of critical illness. Both forms of end-organ injury commonly occur in similar settings of systemic inflammatory response syndrome, shock, and evolving multiple organ dysfunction. Recent elucidation of the pathobiology of critical illness has led to a more basic mechanistic understanding of the complex interplay between injured organs in patients with multiple organ dysfunction syndrome; this has been aptly called 'the slippery slope of critical illness' [Kidney Int Suppl 1998;66:S25-S33]...
