Nattachai SrisawatThailand Moderator Precision Sepsis-AKI — Biomarkers, AI and Phenotyping in the Asia-PacificSepsis-associated AKI in the Asia-Pacific carries a burden that global datasets underrepresent. In the SEA-AKI prospective multicentre ICU study, AKI was very common, with stage 3 reaching 28.9%, and infectious disease among the independent risk factors for AKI development. In the InSEA-RRT registry — 2,315 critically ill patients with stage 3 AKI across 24 hospitals in Southeast Asia and India — 47% died during hospitalization, with major adverse kidney events tracked to two years. These cohorts expose the limits of treating sepsis-AKI as one disease. This lecture examines how damage and stress biomarkers, machine-learning models trained on regional rather than imported data, and sub-phenotyping by trajectory and host response can move us from a single creatinine-based label toward actionable patient groups. Emphasis will be on what is deployable in resource-variable settings, where biomarker access is uneven and registry infrastructure is often the practical starting point for precision medicine.Timing of DialysisWhen to start kidney replacement therapy (KRT) in AKI remains one of the most frequent bedside decisions in critical care, and the trial evidence has settled less than it first appears. ELAIN favoured early initiation, AKIKI and IDEAL-ICU did not, STARRT-AKI showed no survival benefit from an accelerated strategy with more dialysis dependence at 90 days, and AKIKI-2 found that delaying further offered no advantage and may cause harm. This session works through illustrative cases rather than trial summaries: the patient with rising creatinine but no urgent indication, refractory hyperkalaemia or acidosis demanding immediate treatment, the fluid-overloaded patient with worsening oxygenation, and the diuretic-responsive patient in whom watchful waiting proves correct. Each case is used to separate absolute indications from the discretionary zone where trials apply. Emphasis will be on practical decision aids — urine output trajectory, furosemide stress testing, fluid balance, and organ-support burden — and on when not starting is the better decision.Acute PD vs Acute HD: Which Is the Right Choice?For AKI requiring kidney replacement therapy outside well-resourced ICUs, the practical question is which modality can be started safely tonight. Acute peritoneal dialysis (PD) needs no vascular access, anticoagulation, water treatment, or machine, but concerns persist about clearance and ultrafiltration control. Our multicentre randomized trial assigned 157 patients with AKI to lower-dosage acute PD (18–24 L/day) or intermittent hemodialysis three times weekly. Sepsis caused 68% of AKI. Twenty-eight-day mortality was 50% versus 49% (risk difference 0.6%), meeting the prespecified noninferiority margin, with comparable dialysis-free survival and seven-day fluid balance. Complications diverged rather than favoured one modality: intradialytic hypotension was more frequent with hemodialysis, hypokalemia with PD. This lecture translates these findings into practice — where lower-dosage PD is a legitimate first choice, where it is not, how to prescribe and monitor it, and how modality availability shapes AKI preparedness in resource-limited settings.

Sejoong KimSouth Korea Speaker Korean Big-Data Experience in AKI and CRRT OutcomesSouth Korea has established a robust nationwide health data infrastructure, enabling large-scale analyses of acute kidney injury (AKI) and continuous renal replacement therapy (CRRT). Leveraging the Health Insurance Review and Assessment Service (HIRA) and National Health Insurance Service (NHIS) databases, Korean researchers have characterized AKI incidence, risk factors, and short- and long-term outcomes across diverse clinical settings. Studies utilizing CRRT data have identified predictors of mortality, renal recovery, and progression to chronic kidney disease. These big-data approaches provide critical real-world evidence, informing clinical practice and guiding future interventional strategies in critically ill patients with AKI.Precision Volume Management in CRRT: Insights from Bioimpedance and BiomarkersOptimal fluid balance is critical in critically ill patients undergoing continuous renal replacement therapy (CRRT), yet accurate volume assessment remains challenging. Bioimpedance analysis (BIA) offers a non-invasive, objective method to quantify fluid overload and guide individualized ultrafiltration targets. Complementing BIA, emerging biomarkers provide dynamic, real-time insights into volume status and end-organ perfusion. Integrating these tools into a precision medicine framework may optimize fluid removal strategies, reduce complications, and improve survival outcomes in CRRT-dependent patients. Prospective validation of this combined approach is warranted.

John ProwleUnited Kingdom Speaker Trajectories of Critical Illness – Defining Endotypes from Routine DataCritical illness is a heterogeneous syndrome characterized by diverse clinical trajectories and variable responses to treatment. Defining biologically and clinically meaningful endotypes using routinely collected healthcare data offers an opportunity to improve risk stratification, prognostication, and personalized therapeutic strategies, enabling earlier intervention, enhanced clinical decision-making, and precision medicine in critical care. In particular the transition from acute to persistent critical illness represents a pivotal phase in intensive care, marked by a shift from the initial disease insult to prolonged organ dysfunction driven by complex host responses. Early identification of patients at risk of this transition remains a major clinical challenge and opportunity.Dynamic Prescription of CRRT Ready for Prime TimeContinuous renal replacement therapy (CRRT) has evolved from a standardized supportive therapy to a platform for precision critical care. Increasing evidence suggests that fixed prescriptions fail to accommodate the dynamic physiological changes encountered during critical illness, resulting in suboptimal solute clearance, fluid management, and metabolic control. Dynamic prescription integrates evolving haemodynamic status, fluid balance, acid–base homeostasis, electrolyte disturbances, and recovery trajectories to optimize therapy delivery while minimizing complications and treatment interruptions. This paradigm supports individualized kidney support rather than protocol-driven care. Emerging decision-support systems and data-driven algorithms have the potential to transform CRRT into a responsive, patient-centred intervention, improving kidney recovery, organ support, and outcomes in critically ill patients. Adapting CRRT for patients with Electrolyte and acid-base disordersContinuous renal replacement therapy (CRRT) is uniquely positioned to provide precise correction of complex electrolyte and acid–base disturbances in critically ill patients. Beyond kidney support, modern CRRT prescriptions can be individualized to account for the severity and evolution of dysnatremia, dyskalemia, calcium disorders, and metabolic acidosis or alkalosis. Customization of dialysate and replacement fluid composition, treatment dose, buffer delivery, and regional citrate anticoagulation enables controlled correction while minimizing the risks of metabolic complications. Dynamic prescription based on serial biochemical monitoring and changing clinical physiology can be embedded into treatment protocols, facilitating safe correction of sodium, potassium, calcium, and bicarbonate abnormalities while optimizing organ support and improving outcomes in critically ill patients. Extracorporeal Therapies in Trauma, Burns and Cerebral OedemaExtracorporeal therapies (ECTs) are an important adjunct in the management of critically ill patients with severe trauma, major burns, and brain injuries. Acute kidney injury, systemic inflammation, rhabdomyolysis, and profound fluid and electrolyte disturbances frequently complicate these conditions, necessitating timely organ support. Continuous kidney replacement therapy (CKRT) provides effective management of metabolic derangements while enabling precise fluid balance in hemodynamically unstable patients. In trauma and burns, ECTs may facilitate the clearance of myoglobin in severe rhabdomyolysis, support fluid management during resuscitation, and could enable removal of damage or pathogen associated molecular patterns mediating multiorgan failure. In patients with cerebral edema, CKRT offers gradual osmotic control and minimizes intracranial pressure fluctuations compared with intermittent dialysis, making it the preferred modality when kidney replacement therapy is required. We will review current evidence, practical considerations, and emerging extracorporeal strategies, highlighting their role in improving physiological stability and supporting recovery in critically ill patients.
