Recent advances in the understanding of acute kidney injury

چکیده
Acute kidney injury (AKI) is a common clinical entity associated with high morbidity and mortality and clinical costs. The pathophysiology is multifaceted and involves inflammation, tubular injury, and vascular damage. Recently identified components include necroptosis, a special form of cell death, and autophagy. Most of the pathophysiological knowledge is obtained from animal models but these do not directly reflect the reality of the clinical situation. Tubular cells have a remarkable capacity to regenerate, and the role of stem/progenitor cells is discussed. Acute kidney injury is frequently associated with chronic kidney disease, and the implications are widespread.

Rapid Diagnosis of acute kidney injury (AKI) associated with cardiac surgery, using the liver type fatty acid binding protein (L-FABP) biomarker
Abstract Background and objectives: cardiac surgery is often associated with acute kidney injury (AKI). Nowadays, AKI is typically diagnosed by an increase in serum creatinine, which is a delayed and unreliable biomarker. Recent studies recommended using the liver type fatty acid binding protein (L-FABP) as an early biomarker. Material and Methods: The urine samples of 18 adult patients undergo...
متن کاملRisk Factors of Acute Kidney Injury in Patients with Sepsis; A Cross-Sectional Study
Background and Objective: Due to the importance of acute kidney injury associated in patients with sepsis and the impact of various factors on mortality and hospital stay of these patients, this study was conducted to investigate the clinical features and risk factors for acute kidney injury in patients with sepsis. In addition, we examined whether the severity of acute kidney injury affected c...
متن کاملAdvances in understanding ischemic acute kidney injury
Acute kidney injury (AKI) is independently associated with increased morbidity and mortality. Ischemia is the leading cause of AKI, and short of supportive measures, no currently available therapy can effectively treat or prevent ischemic AKI. This paper discusses recent developments in the understanding of ischemic AKI pathophysiology, the emerging relationship between ischemic AKI and develop...

متن کاملAcute kidney injury: changing lexicography, definitions, and epidemiology.
In recent years, there have been numerous advances in understanding the molecular determinants of functional kidney injury after ischemic and/or toxic exposure. However, translation of successful novel therapies designed to attenuate kidney functional injury from animal models to the clinical sphere has had modest results. This lack of translatability is at least in part due to lack of sufficie...
