This week’s clinical focus
Evaluating Patterns and Outcomes in the Prescription of Incremental Peritoneal Dialysis in Support of Shared Decision-Making
Among 527 incident patients starting incremental peritoneal dialysis, 64% remained on the same starting prescription at one year and 36% had not incremented by two years. Younger age, male sex, and lower albumin predicted earlier escalation. Transfers to haemodialysis were mainly associated with lifestyle, fluid overload, uraemic symptoms, younger age, diabetes, lower albumin, and lower starting eGFR. Mortality was low, but the proposed score needs external validation.
Clinical impact: Supports individualized incremental-PD discussions when residual kidney function and clinical status permit; it is observational evidence, not proof that incremental PD is universally safe.
Clinical relevance: High

Glucagon-Like Peptide-1 Receptor Agonist Use and Risks of Hospitalization and Mortality in Patients with End-Stage Kidney Disease
In matched adults starting in-centre haemodialysis, GLP-1 receptor agonist use in the first month was associated with lower hospitalization rates (IRR 0.91; 95% CI 0.87–0.96) and mortality rates (IRR 0.83; 95% CI 0.73–0.95). The cohort was predominantly diabetic and observational, so residual confounding and treatment-selection bias remain possible.
Clinical impact: Encouraging real-world signal for GLP-1 receptor agonists in selected patients with ESKD, but treatment decisions should follow approved indications, tolerability, and individualized metabolic assessment.
Clinical relevance: Moderate

Proteinuria and Kidney Function Trajectories in Patients with Advanced CKD: Insights from CRIC and KNOW-CKD Studies
Across 2,727 people with eGFR 15–45 mL/min/1.73 m², higher urine protein-to-creatinine ratios strongly predicted CKD progression. Compared with <0.5 g/g, time-updated ratios of 0.5–1.0, 1.0–3.0, and ≥3.0 g/g were associated with hazard ratios of 2.58, 5.61, and 12.88, respectively. Higher proteinuria also corresponded to faster eGFR decline and shorter projected time to eGFR 10.
Clinical impact: Reinforces proteinuria as a powerful prognostic marker in advanced CKD and supports repeated quantitative assessment alongside eGFR and treatment response.

Dialysis Discontinuation Rates at Low Levels of Kidney Function in Patients with Acute Kidney Injury on Intermittent Hemodialysis
In 85 hemodynamically stable patients with dialysis-requiring AKI, measured creatinine clearance discriminated near-term dialysis need better than urine output. Dialysis was not required during the following week in 81% of collections with clearance 10–20 mL/min and 44% with clearance 5–<10 mL/min. The analysis used protocolized indications and blinded timed collections.
Clinical impact: Supports using timed clearance and clinical indications when assessing dialysis liberation; results should not be applied without attention to haemodynamic stability, volume, electrolytes, and uraemic complications.

Asia-Pacific Summit on Implementation of Clinical Practice Guidelines on Diabetes and Blood Pressure Management in Chronic Kidney Disease: A KDIGO Summit Report
A KDIGO Asia-Pacific summit identified barriers to implementing diabetes and blood-pressure guidance in CKD across 13 countries or regions. Priorities included lifestyle support, integrated team-based care, albuminuria screening, and access to guideline-directed therapies. The report proposes actions tailored to local income level and health-system capacity rather than a single universal implementation model.
Clinical impact: Useful systems-level framework for adapting CKD care pathways; it is a consensus/implementation report, not comparative outcome evidence.
Clinical relevance: Moderate

Outcomes from the International Society of Nephrology Forum on Complement Therapeutics in C3G & IgAN
An international expert forum reviewed the emerging role of complement inhibition in C3G, immune-complex MPGN, and IgA nephropathy. The report emphasizes uncertainty around patient selection, complement biomarkers, autoantibodies, genetics, biopsy findings, and how new inhibitors should fit within existing therapy. It outlines priorities for real-world use and future research.
Clinical impact: Helpful for framing complement-targeted treatment decisions, but forum recommendations should not be interpreted as a substitute for approved indications or trial-level evidence.
Clinical relevance: Moderate

Unveiling the Immuno-Inflammatory Endotype of Sepsis-Associated Acute Kidney Injury: A Machine Learning-Based Approach
Among 1,551 patients with sepsis, new AKI occurred in 44.8%. A high-risk immune endotype combined immunoglobulin A, procalcitonin, complement C3 depletion, and altered CD4-positive T-cell patterns. An XGBoost model integrating immune and routine clinical variables achieved an AUC of 0.914 versus 0.788 for the clinical model. External validation and impact testing remain necessary.
Clinical impact: Promising early-risk stratification research, but the model is not ready to guide bedside decisions without independent validation and calibration.
Clinical relevance: Moderate

Comparison of Bortezomib with Dexamethasone and Thalidomide with Dexamethasone in Monoclonal Immunoglobulin Deposition Disease
In 72 biopsy-confirmed cases, bortezomib/dexamethasone produced higher hematologic and renal response rates than thalidomide/dexamethasone and was associated with better five-year renal survival (73% versus 51%). Neurotoxicity was less frequent with bortezomib than thalidomide. Eight transplant-eligible patients had deeper hematologic responses after autologous stem-cell transplantation. Confounding by treatment selection remains possible.
Clinical impact: Supports bortezomib-based plasma-cell therapy as an important regimen to discuss with haematology, while recognizing the retrospective design and need for individualized toxicity assessment.

Tailoring HLA Antibody Monitoring Post-Transplantation
This review recommends risk-adapted rather than fixed HLA-antibody monitoring in pediatric kidney recipients. It highlights prolonged allograft exposure, adolescence-related nonadherence, immunosuppressive regimen, and prior immunologic risk as reasons to individualize testing intervals and trigger-based reassessment. Mean fluorescence intensity should be interpreted in clinical context rather than used as an isolated decision threshold.
Clinical impact: Provides a practical framework for pediatric transplant surveillance, but monitoring schedules should follow local protocols and multidisciplinary interpretation.
Clinical relevance: High

Peritoneal Dialysis Catheter Flushing in Children: A National Survey of Practice Patterns
Among 43 of 60 US pediatric PD centers responding, 83% had a flushing protocol and 98% routinely flushed catheters, but timing, solution, volume, heparin use, and management of bloody effluent varied substantially. Weekly flushing was common and 10 mL/kg was a typical volume. The survey demonstrates practice variation rather than comparative effectiveness.
Clinical impact: Highlights an actionable standardization gap in pediatric PD; prospective multicenter studies are needed before one flushing protocol is adopted broadly.
Clinical relevance: Moderate

Cancer Risk in Kidney Transplant Recipients on Belatacept Versus Calcineurin Inhibitors: A Systematic Review and Meta-Analysis
Across 3,070 kidney transplant recipients, belatacept was not associated with a statistically significant difference in skin cancer or overall cancer compared with calcineurin-inhibitor regimens. Conversion from calcineurin inhibitors showed a non-significant trend toward higher cancer risk than de novo belatacept. The evidence is limited by event numbers, heterogeneity, and cancer outcomes not being primary endpoints.
Clinical impact: Reassuring but not definitive safety evidence; cancer screening and immunosuppression decisions should remain individualized.
Clinical relevance: Moderate

Underutilization of Preemptive Waitlisting for Prior Living Donors Who Develop ESKD
This verified Kidney360 record addresses access to preemptive waitlisting among prior living kidney donors who later develop ESKD. PubMed did not provide an abstract at review time, so this entry is limited to the verified title and publication record; no unverified numerical findings are inferred.
Clinical impact: Potentially important for donor follow-up and transplant access policy, but readers should consult the full article before drawing clinical conclusions.
Clinical relevance: Moderate
