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.
