Recent basic studies regarding pathogenesis, the new agents concerning inflammation, mitochondria biogenesis may possible new therapeutic targets for AKI.

Novel biomarker-guided early diagnosis of AKI may facilitate exploration of novel anti-inflammatory and antioxidant therapies in specific AKI syndromes, such as sepsis-induced AKI, and open new avenues to facilitate renal recovery and prevent short and long-term complications. Recently, survivors of episodes of AKI who are at risk for the development or worsening of CKD need greater attention. The burden of CKD on the global health care system is well documented, so the importance of preventing or minimizing CKD progression in survivors of AKI episodes cannot be overstated. To this end, the recent KDIGO clinical practice guideline proposed a new conceptual model, called acute kidney disease, to Doxorubicin in vitro highlight the need to follow survivors of AKI episodes in the near term and monitor development of signs and symptoms of CKD, with a focus on screening for markers of kidney damage (i.e., proteinuria) and/or reduced GFR. Major risk factors for CKD progression after AKI include GPCR Compound Library screening advanced age, diabetes mellitus, hypertension, heart failure, preexisting CKD (as defined by proteinuria or educed GFR), and low levels of serum albumin, a dual marker of nutrition and inflammation. The presence of these risk factors should alert

practitioners to be especially vigilant for CKD development after an episode of AKI. The survive episodes of AKI be followed regularly to assess for early evidence of CKD (i.e., development of hypertension, proteinuria, or reduced GFR) to slow progression of diagnosed CKD to ESRD. In this section, many drug therapy including renin-angiotensin system blocker is available. In summary besides renal replacement therapy, no other supportive drugs are available for patients with AKI. The best therapy for patients with AKI seems to be the avoidance of further injury to the kidney. Nutlin-3 in vivo AKI to CKD transition should be cared by

monitoring by change of GFR, presence of proteinuria or hypertension. ZHANG HONG Renal Division, Department of Medicine, Peking University First Hospital & Peking University Institute of Nephrology, China IgA nephropathy (IgAN) is the most common primary glomerulonephritis worldwide and widely considered to be a polygenic disease. Although exact pathogenesis is still unclear, multi-hit mechanism was proposed for this disease. To further clarify genetic factors involved in IgAN and draw clues to the underlying pathogenesis, three groups of scientists from England, US and China, independently performed genome-wide association studies (GWAS) in IgAN and identified several IgAN susceptible loci. One of the identified genomic region 1q32 contains complement factor H (CFH) and the related CFHR3, CFHR1, CFHR4, CHFR2, CFHR5 genes.
