Abstract 52: KDIGO (Kidney Disease: Improving Global Outcomes) Guideline Update On The Management Of Blood Pressure In Chronic Kidney Disease: What’s New And What’s Different From Other Guidelines
Bibliographic record
Abstract
Introduction: In 2012, KDIGO released a guideline on BP management in CKD not receiving dialysis. The emergence of new trials and meta-analyses coupled with wider recognition of the importance of standardized BP measurement protocols have prompted a call to update the 2012 guideline. This summary will outline the changes to the prior recommendations and highlight similarities to guidelines from ACC/AHA and ESC/ESH. Methods: A systematic review was undertaken to formally assess the following issues: 1) BP measurement; 2) lifestyle interventions; BP management in 3) patients with CKD, with and without diabetes, 4) kidney transplant recipients, and 5) children with CKD. Results: A total of 6863 citations were screened. Of these, 290 RCTs, 14 observational studies, and 35 systematic reviews were included in the evidence review. A major addition to the KDIGO 2021 guideline is a chapter devoted to BP measurement. KDIGO recommends the use of standardized office BP over routine BP. Out-of-office measurements (ABPM, HBPM) can be used to complement standardized readings. This emphasis on standardized office BP measurement is similar to recommendations from ACC/AHA and ESC/ESH. A systolic BP target of <120 mm Hg is suggested; however, the guidance emphasizes that the target is only applicable when BP is measured using standardized office protocols. RASi are the preferred agents for adults with CKD with increased albuminuria. For lifestyle interventions, dietary sodium intake should be limited to <2 g/day, and ≥150 minutes/week of physical activity is recommended. A BP target of <130/80 mm Hg and use of CCB or ARB are preferred in kidney transplant recipients. BP in children with CKD should be guided by 24-hour MAP using ambulatory monitoring, targeting ≤50th percentile for age, sex, and height. Similar to ACC/AHA and ESC/ESH guidelines, KDIGO also encourages shared-decision making between patients and clinicians in the individualization of BP therapy. Conclusions: KDIGO has revised its guideline for BP management in CKD based on a rigorous development process and emerging new evidence underscoring the importance of standardized office BP measurement and a lower systolic BP target of <120 mm Hg for achieving potential cardiovascular, kidney, and mortality benefits.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
