    Abstract This book presents up-to-date information on the clinical-pathophysiological features of acute renal injury and discusses the KDIGO diagnostic criteria, as well as novel experimental findings, including in the area of regenerative medicine. It also highlights the clinical-pathophysiological importance of AKI in clinical settings, including differential diagnoses and management of AKI. In the past, the pathology associated with sudden renal impairment was characterized as acute renal failure (ARF). However, in the 2000s, the joint efforts of specialists in fields including nephrology, intensive care medicine, and cardiovascular medicine led to the introduction of a novel concept known as acute kidney injury (AKI). As medical care progressed, patients such as high-risk elderly subjects who were not deemed to be candidates for invasive therapy came to be treated in intensive care units (ICUs). As a result, kidney injury as a subset of multiple organ failure was re-considered as AKI, especially in intensive care medicine. AKI was then proposed as a novel disease concept to emphasize the importance of early diagnosis and early intervention to improve prognosis. Presenting novel features, such as the definition of AKI, risk factors and management; biomarkers, such as neutrophil gelatinase-associated lipocalin (NGAL) and L-type fatty acid-binding protein (L-FABP); long-term outcomes of AKI; as well as renal regeneration using iPS cell, manipulation of embryonic genes, and Xenotransplanted embryonic kidney, this book is of interest to all physicians and researchers in this field around the globe.

    Abstract Acute kidney injury (AKI) is a threatening medical condition associated with poor outcomes at different settings. The development of standardized diagnostic criteria and new biomarkers addressed significant clinical impacts of AKI and the need for an early AKI detection, respectively. There have been some breakthroughs in understanding the pathogenesis of AKI through basic research; however, treatments against AKI aside from renal replacement therapy (RRT) have not shown adequate successful results. Biomarkers that could identify good responders to certain treatment are expected to facilitate translation of basic research findings. Most patients with severe AKI treated with RRT died due to multiple-organ failure, not renal dysfunction. Hence, it is essential to identify other organ dysfunctions induced by AKI as organ crosstalk. Also, a multidisciplinary approach of critical care nephrology is needed to evaluate a complex organ crosstalk in AKI. For disruptive innovation for AKI, we further explore these new aspects of AKI, which previously were considered outside the scope of nephrology.

    Abstract The interactions between the kidney and heart are well studied and frequently lumped together as cardiorenal syndrome. It is believed that the sympathetic nervous system is involved in the mechanism of kidney injury caused by heart failure, but direct evidence is still lacking. In chronic renal fibrosis, sympathetic nerve activation was demonstrated to be harmful by unilateral ureteral obstruction and post-ischemia reperfusion injury models. On the other hand, sympathetic nerve activation seemed protective in acute kidney injury models such as ischemia reperfusion injury and lipopolysaccharide injection. Our recent investigation showed that post-ischemic renal fibrosis was attenuated when preexisting heart failure was induced by transverse aortic constriction surgery and renal denervation canceled this protection. These findings suggest sympathetic nerve activation in cardiorenal syndrome may be protective on chronic renal fibrosis development caused by ischemic an insult.

    Abstract No specific drug against acute kidney injury is clinically available and novel findings in basic research urgently need to be translated to the clinical in order to improve the outcome of patients. Chen and colleagues demonstrated the protective role of tenascin-C on acute kidney injury by using animal models and in vitro and ex vivo experiments. We need to find a better way to overcome the barrier for translation of this new target.

    Abstract Acute kidney injury (AKI) occurs in about half of critically ill patients and is associated with high in-hospital mortality, increased long-term mortality postdischarge, and subsequent progression to chronic kidney disease. Numerous clinical studies have shown that AKI is often complicated by dysfunction of distant organs, which is a cause of the high mortality incidence associated with AKI. Experimental studies have elucidated many mechanisms of AKI-induced distant organ injury, which include inflammatory cytokines, oxidative stress, and immune responses. This review provides an update on evidence of organ crosstalk and potential therapeutics for AKI-induced organ injuries, and presents the new concept of a systemic organ network that balances homeostasis and involves multi-organ crosstalk beyond that of the kidney with a single distant organ.
