    Acute Kidney Injury Network: report of an initiative to improve outcomes in acute kidney injury
    (BioMed Central, 2007-03-01) Mehta, Ravindra L.; Kellum, John A.; Shah, Sudhir V.; Molitoris, Bruce A.; Ronco, Claudio; Warnock, David G.; Levin, Adeera; Medicine, School of Medicine
    Introduction Acute kidney injury (AKI) is a complex disorder for which currently there is no accepted definition. Having a uniform standard for diagnosing and classifying AKI would enhance our ability to manage these patients. Future clinical and translational research in AKI will require collaborative networks of investigators drawn from various disciplines, dissemination of information via multidisciplinary joint conferences and publications, and improved translation of knowledge from pre-clinical research. We describe an initiative to develop uniform standards for defining and classifying AKI and to establish a forum for multidisciplinary interaction to improve care for patients with or at risk for AKI. Methods Members representing key societies in critical care and nephrology along with additional experts in adult and pediatric AKI participated in a two day conference in Amsterdam, The Netherlands, in September 2005 and were assigned to one of three workgroups. Each group's discussions formed the basis for draft recommendations that were later refined and improved during discussion with the larger group. Dissenting opinions were also noted. The final draft recommendations were circulated to all participants and subsequently agreed upon as the consensus recommendations for this report. Participating societies endorsed the recommendations and agreed to help disseminate the results. Results The term AKI is proposed to represent the entire spectrum of acute renal failure. Diagnostic criteria for AKI are proposed based on acute alterations in serum creatinine or urine output. A staging system for AKI which reflects quantitative changes in serum creatinine and urine output has been developed. Conclusion We describe the formation of a multidisciplinary collaborative network focused on AKI. We have proposed uniform standards for diagnosing and classifying AKI which will need to be validated in future studies. The Acute Kidney Injury Network offers a mechanism for proceeding with efforts to improve patient outcomes.

    (American Medical Association, 2022-09-01) Goldstein, Stuart L.; Akcan-Arikan, Ayse; Alobaidi, Rashid; Askenazi, David J.; Bagshaw, Sean M.; Barhight, Matthew; Barreto, Erin; Bayrakci, Benan; Bignall, Orville N. R.; Bjornstad, Erica; Brophy, Patrick D.; Chanchlani, Rahul; Charlton, Jennifer R.; Conroy, Andrea L.; Deep, Akash; Devarajan, Prasad; Dolan, Kristin; Fuhrman, Dana Y.; Gist, Katja M.; Gorga, Stephen M.; Greenberg, Jason H.; Hasson, Denise; Heydari Ulrich, Emma; Iyengar, Arpana; Jetton, Jennifer G.; Krawczeski, Catherine; Meigs, Leslie; Menon, Shina; Morgan, Jolyn; Morgan, Catherine J.; Mottes, Theresa; Neumayr, Tara M.; Ricci, Zaccaria; Selewski, David; Soranno, Danielle E.; Starr, Michelle; Stanski, Natalja L.; Sutherland, Scott M.; Symons, Jordan; Tavares, Marcelo S.; Wong Vega, Molly; Zappitelli, Michael; Ronco, Claudio; Mehta, Ravindra L.; Kellum, John; Ostermann, Marlies; Basu, Rajit K.; Pediatric ADQI Collaborative; Pediatrics, School of Medicine
    Importance: Increasing evidence indicates that acute kidney injury (AKI) occurs frequently in children and young adults and is associated with poor short-term and long-term outcomes. Guidance is required to focus efforts related to expansion of pediatric AKI knowledge. Objective: To develop expert-driven pediatric specific recommendations on needed AKI research, education, practice, and advocacy. Evidence review: At the 26th Acute Disease Quality Initiative meeting conducted in November 2021 by 47 multiprofessional international experts in general pediatrics, nephrology, and critical care, the panel focused on 6 areas: (1) epidemiology; (2) diagnostics; (3) fluid overload; (4) kidney support therapies; (5) biology, pharmacology, and nutrition; and (6) education and advocacy. An objective scientific review and distillation of literature through September 2021 was performed of (1) epidemiology, (2) risk assessment and diagnosis, (3) fluid assessment, (4) kidney support and extracorporeal therapies, (5) pathobiology, nutrition, and pharmacology, and (6) education and advocacy. Using an established modified Delphi process based on existing data, workgroups derived consensus statements with recommendations. Findings: The meeting developed 12 consensus statements and 29 research recommendations. Principal suggestions were to address gaps of knowledge by including data from varying socioeconomic groups, broadening definition of AKI phenotypes, adjudicating fluid balance by disease severity, integrating biopathology of child growth and development, and partnering with families and communities in AKI advocacy. Conclusions and relevance: Existing evidence across observational study supports further efforts to increase knowledge related to AKI in childhood. Significant gaps of knowledge may be addressed by focused efforts.

    Pediatric AKI in the real world: changing outcomes through education and advocacy-a report from the 26th Acute Disease Quality Initiative (ADQI) consensus conference
    (Springer, 2024) Mottes, Theresa; Menon, Shina; Conroy, Andrea; Jetton, Jennifer; Dolan, Kristin; Arikan, Ayse Akcan; Basu, Rajit K.; Goldstein, Stuart L.; Symons, Jordan M.; Alobaid, Rashid; Askenazi, David J.; Bagshaw, Sean M.; Barhight, Matthew; Barreto, Erin; Bayrakci, Benan; Bignall, O. N., II; Bjornstad, Erica; Brophy, Patrick; Charlton, Jennifer; Chanchlani, Rahul; Conroy, Andrea L.; Deep, Akash; Devarajan, Prasad; Fuhrman, Dana; Gist, Katja M.; Gorga, Stephen M.; Greenberg, Jason H.; Hasson, Denise; Heydari, Emma; Iyengar, Arpana; Krawczeski, Catherine; Meigs, Leslie; Morgan, Catherine; Morgan, Jolyn; Neumayr, Tara; Ricci, Zaccaria; Selewski, David T.; Soranno, Danielle; Stanski, Natalja; Starr, Michelle; Sutherland, Scott M.; Symons, Jordan; Tavares, Marcelo; Vega, Molly; Zappitelli, Michael; Ronco, Claudio; Mehta, Ravindra L.; Kellum, John; Ostermann, Marlies; ADQI 26 workgroup; Pediatrics, School of Medicine
    Background: Acute kidney injury (AKI) is independently associated with increased morbidity and mortality across the life course, yet care for AKI remains mostly supportive. Raising awareness of this life-threatening clinical syndrome through education and advocacy efforts is the key to improving patient outcomes. Here, we describe the unique roles education and advocacy play in the care of children with AKI, discuss the importance of customizing educational outreach efforts to individual groups and contexts, and highlight the opportunities created through innovations and partnerships to optimize lifelong health outcomes. Methods: During the 26th Acute Disease Quality Initiative (ADQI) consensus conference, a multidisciplinary group of experts discussed the evidence and used a modified Delphi process to achieve consensus on recommendations on AKI research, education, practice, and advocacy in children. Results: The consensus statements developed in response to three critical questions about the role of education and advocacy in pediatric AKI care are presented here along with a summary of available evidence and recommendations for both clinical care and research. Conclusions: These consensus statements emphasize that high-quality care for patients with AKI begins in the community with education and awareness campaigns to identify those at risk for AKI. Education is the key across all healthcare and non-healthcare settings to enhance early diagnosis and develop mitigation strategies, thereby improving outcomes for children with AKI. Strong advocacy efforts are essential for implementing these programs and building critical collaborations across all stakeholders and settings.

    Progression after AKI: Understanding Maladaptive Repair Processes to Predict and Identify Therapeutic Treatments
    (American Society of Nephrology, 2016-03) Basile, David P.; Bonventre, Joseph V.; Mehta, Ravindra; Nangaku, Masaomi; Unwin, Robert; Rosner, Mitchell H.; Kellum, John A.; Ronco, Claudio; Department of Cellular & Integrative Physiology, IU School of Medicine
    Recent clinical studies indicate a strong link between AKI and progression of CKD. The increasing prevalence of AKI must compel the nephrology community to consider the long-term ramifications of this syndrome. Considerable gaps in knowledge exist regarding the connection between AKI and CKD. The 13th Acute Dialysis Quality Initiative meeting entitled "Therapeutic Targets of Human Acute Kidney Injury: Harmonizing Human and Experimental Animal Acute Kidney Injury" convened in April of 2014 and assigned a working group to focus on issues related to progression after AKI. This article provides a summary of the key conclusions and recommendations of the group, including an emphasis on terminology related to injury and repair processes for both clinical and preclinical studies, elucidation of pathophysiologic alterations of AKI, identification of potential treatment strategies, identification of patients predisposed to progression, and potential management strategies.

    Renal Hemodynamics in AKI: In Search of New Treatment Targets
    (American Society of Nephrology, 2016-01) Matejovic, Martin; Ince, Can; Chawla, Lakhmir S.; Blantz, Roland; Molitoris, Bruce A.; Rosner, Mitchell H.; Okusa, Mark D.; Kellum, John A.; Ronco, Claudio; Department of Medicine, IU School of Medicine
    Novel therapeutic interventions are required to prevent or treat AKI. To expedite progress in this regard, a consensus conference held by the Acute Dialysis Quality Initiative was convened in April of 2014 to develop recommendations for research priorities and future directions. Here, we highlight the concepts related to renal hemodynamics in AKI that are likely to reveal new treatment targets on investigation. Overall, we must better understand the interactions between systemic, total renal, and glomerular hemodynamics, including the role of tubuloglomerular feedback. Furthermore, the net consequences of therapeutic maneuvers aimed at restoring glomerular filtration need to be examined in relation to the nature, magnitude, and duration of the insult. Additionally, microvascular blood flow heterogeneity in AKI is now recognized as a common occurrence; timely interventions to preserve the renal microcirculatory flow may interrupt the downward spiral of injury toward progressive kidney failure and should, therefore, be investigated. Finally, development of techniques that permit an integrative physiologic approach, including direct visualization of renal microvasculature and measurement of oxygen kinetics and mitochondrial function in intact tissue in all nephron segments, may provide new insights into how the kidney responds to various injurious stimuli and allow evaluation of new therapeutic strategies.
