  VinCent WuTaiwan Speaker AKD Care Redefined: Diabetes, Hypertension, and Strategies for Long-Term Health Traditional acute kidney injury (AKI) classifications, centered around semi-anatomical lines, no longer suffice in capturing the complexity of AKI. Subphenotyping, enriched with AKI biomarkers, holds insights into distinct risk profiles and tailored treatment strategies, redefining AKI and contributing to improved clinical management (Critical Care). Incorporating kidney biomarkers into strategies for early AKI detection and the initiation of AKI care bundles has shown greater effectiveness than using care bundles without these novel biomarkers. Our investigations have made notable advancements in identifying water-soluble regulatory iron hepcidin as a promising early biomarker for predicting postoperative acute kidney injury. Beyond hepcidin, our research extended into the exploration of predictive biomarkers, such as HJV, NGAL, and cFGF-23, uncovering their potential in prognosticating the occurrence and severity of AKI (Cell Death Dis, Antioxidants & redox signaling). The amalgamation of these biomarkers with existing clinical AKI scores holds immense promise in revolutionizing critical care and ushering in a new era of personalized patient management. Moreover, our endeavors have transcended theoretical advancements, with successful patent acquisition for AKI biomarkers attesting to our commitment. We were the inaugural contributors to the discourse on the effects of indoxyl sulfate on the tubulogenesis capability of endothelial progenitor cells and cell aging in acute kidney injury(Angiogenesis). A comprehensive review of the long-term prognosis of acute kidney injury, encompassing impacts on the heart, brain, bone lesions, gastrointestinal, and tissue carcinogenesis, was presented. (JASN, KI, cJASN, JAHA, ICM, CC). Our team posited that transferring post-AKI patients to nephrologists for care could reduce overall mortality and cardiovascular events (Value in Health). Through integrated analysis, we demonstrated that standard dialysis would increase the number of patients avoiding dialysis (CC), stimulating fervent discussions among AKI physicians at international conferences. Notably, we were global trailblazers in proposing that acute kidney disease, regardless of AKI presence, leads to mortality and end-stage kidney disease(eClinicalMedicine ). Although the evidence for patients with acute kidney disease (AKD) is still lacking, several potential pharmacological agents may improve outcomes, including but not limited to angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, mineralocorticoid receptor antagonists, sodium-glucose cotransporter 2 inhibitors, and glucagon-like peptide 1 receptor agonists (JAMA NO). In conclusion, accurate prognosis prediction and effective treatment for AKD are critical yet unmet clinical needs. Future studies are urgently needed to improve patient care in this complex and rapidly evolving field.
• Organ Crosstalk in AKI
  Kent DoiJapan Speaker Organ Crosstalk in AKIAcute kidney injury (AKI) is frequently complicated by distant organ dysfunction, significantly increasing patient morbidity and mortality. Recent clinical and experimental evidence highlights complex inter-organ crosstalk mechanisms, such as systemic cytokine release, oxidative stress, immune dysregulation, and damage-associated molecular patterns (DAMPs), that mediate extrarenal tissue injury. Experimental studies demonstrate distinct pathophysiological axes connecting the injured kidney with the heart and lungs. Specifically, mitochondrial dysfunction plays a critical role in acute cardiorenal syndrome. Furthermore, in AKI-induced acute lung injury, in addition to activation of the HMGB1–Toll-like receptor 4 (TLR4) pathway and formation of neutrophil extracellular traps (NETs), recent studies have reported a novel pathophysiological mechanism of impaired gas exchange mediated by neutrophil retention. This presentation provides an updated overview of the molecular pathways driving AKI-induced distant organ crosstalk, emphasizing key pathophysiology involving the heart and lungs, and discusses targeted therapeutic strategies to improve clinical outcomes in multi-organ failure.Heterogeneity and Future Direction of Major Adverse Kidney EventsThe "AKI/AKD/CKD axis" represents a critical continuum in nephrology, highlighting that acute kidney injury (AKI) is not merely a self-limiting episode but a potent driver of chronic kidney disease (CKD). Numerous clinical studies have reported the epidemiology of the AKI-to-CKD transition, demonstrating how recurrent or severe AKI accelerates renal decline. Crucially, methodological heterogeneity in defining Major Adverse Kidney Events (MAKE), as highlighted by our recent scoping review (Maeda et al., Intensive Care Med 2024), complicates the interpretation of clinical trial outcomes. To ensure the success of future clinical trials targeting AKI and the AKI-to-CKD transition, we must not only identify optimal therapeutic targets, but also establish standardized outcomes that directly align with improved patient care.Targeted Polymyxin B Hemadsorption in Sepsis: Lessons from Japanese Experience and Patient SelectionPolymyxin B haemadsorption (PMX-HA) has a long clinical history in Japan in the treatment of endotoxemia and septic shock. However, recent international randomized controlled trials and clinical guidelines have caused controversy regarding its routine use, citing inconsistent survival benefits in unselected populations. This presentation reviews the evolution of PMX-HA, from its origins in extensive Japanese clinical experience to modern precision medicine approaches in intensive care. Recent secondary analyses and real-world studies have highlighted significant heterogeneity in treatment effects, underscoring the necessity of appropriate patient selection. Subgroup analyses from the EUPHRATES trial demonstrated the potential efficacy of PMX-HA in patients with moderate-to-high endotoxin activity levels (EAA 0.6–0.9) and high severity of organ failure. Furthermore, machine learning applications such as causal forest modelling on large observational and trial cohorts have successfully identified specific biomarker profiles and clinical characteristics that define true responders.

• AKI in the Mechanical Circulatory Support
  Keith Wille Speaker Connectology with Hybrid Systems: ECMO, Apheresis, ECCO2RExtracorporeal life support technologies are increasingly used in critical care settings, with integrating extracorporeal membrane oxygenation (ECMO), apheresis, and extracorporeal carbon dioxide removal (ECCO₂R) to provide multi-organ support. This session explores the principles, clinical applications, and challenges of extracorporeal systems and their integration into CRRT, focusing on the interaction between ECMO and renal replacement therapy (CRRT), the role of ECCO2R in respiratory failure, and the combination of apheresis for immunomodulation. Through discussion, participants will gain an understanding of patient selection, circuit configurations, anticoagulation strategies, and the physiological considerations that impact patient outcomes. Emphasis will be placed on optimizing patient management, recognizing complications, and developing a structured approach to hybrid extracorporeal therapy.AKI in Mechanical Circulatory SupportAcute kidney injury (AKI) is a frequent and important complication of cardiogenic shock and is strongly associated with adverse outcomes. Its pathogenesis is multifactorial, reflecting reduced cardiac output and renal perfusion, venous congestion, neurohormonal activation, systemic inflammation, vasopressor exposure, and hemodynamic instability. Mechanical circulatory support (MCS) may interrupt this cycle by restoring cardiac output, reducing venous congestion, and decreasing vasopressor requirements; however, MCS itself may contribute to kidney injury through hemolysis, embolic events, limb ischemia and rhabdomyolysis, bleeding, contrast exposure, and device-related hemodynamic disturbances. This presentation will review the mechanisms and clinical impact of AKI across commonly used temporary and durable MCS platforms, including intra-aortic balloon pumps, microaxial flow pumps, temporary ventricular assist devices, and durable LVADs. Particular emphasis will be placed on identifying potentially reversible contributors to AKI, understanding the relationship between timing of circulatory support and renal recovery, and managing patients who require concurrent kidney replacement therapy. Practical considerations for CRRT, including vascular access, anticoagulation, ultrafiltration, and interactions between CRRT and MCS, will also be discussed. How do I care for the Patient with ARDS and AKIAcute respiratory distress syndrome (ARDS) and acute kidney injury (AKI) frequently coexist in critically ill patients and together are associated with substantial morbidity and mortality. Their management is closely intertwined: mechanical ventilation, positive end-expiratory pressure, hemodynamic support, and fluid administration may influence renal perfusion and venous congestion, while AKI and fluid accumulation can worsen pulmonary edema, impair gas exchange, and complicate ventilator management. This presentation will provide a practical approach to the patient with concurrent ARDS and AKI, integrating pulmonary and kidney-focused strategies. Key topics will include lung-protective ventilation and its renal consequences, assessment and management of volume status, the role of conservative fluid strategies and de-resuscitation, and the use of diuretics and kidney replacement therapy to achieve fluid-balance goals. Attention will be given to when and how continuous renal replacement therapy can support fluid management in patients with severe respiratory failure, including those with hemodynamic instability. The session will emphasize coordinated decision-making between critical care and nephrology teams to balance lung protection, kidney perfusion, and overall organ support.
