Pretransplant Type 2 Hepatorenal Syndrome Is Associated With Persistently Impaired Renal Function After Liver Transplantation
Bibliographic record
Abstract
BACKGROUND: Type 2 hepatorenal syndrome (HRS2) is a functional renal impairment complicating end-stage liver disease. Although it is reversible after liver transplantation, long-term posttransplant outcomes in HRS2 patients remain ill-defined. METHODS: Retrospective, matched case-control (1:2) study of all adult HRS2 patients transplanted in our institution between 2000 and 2012. The HRS2 patients were identified from our electronic transplant database, and matched with controls for the following variables: age, sex, etiology, diabetes mellitus, and year of transplant. RESULTS: Forty-two HRS2 patients were compared to 83 controls. At the time of transplant, HRS2 patients had an estimated glomerular filtration rate of 41 ± 1 mL/min per 1.73 m. The HRS2 patients had greater intraoperative packed red blood cell transfusion (P = 0.002), and longer intensive care unit (P = 0.01) as well as total hospital length of stay (P = 0.03). Reversal of HRS2 occurred in 88.1% patients, 5.7 ± 0.5 days after transplantation. Although HRS2 patients had lower initial exposure to calcineurin inhibitors, a greater proportion of HRS2 patients had chronic kidney disease stage 3 (CKD3) at 3 (53.8% vs 28.4%; P = 0.007) and 12 months (59.5% vs 38.2%; P = 0.03) compared to controls. One-year survival was similar between the 2 groups (log-rank P = 0.82). On multivariate analysis, pretransplant HRS2 was associated with CKD3 at 3 (odds ratio, 3.73; 95% confidence interval, 1.54-9.03; P = 0.004) and 12 months (odds ratio, 3.23; 95% confidence interval, 1.37-7.64; P = 0.007) after transplantation. CONCLUSIONS: Liver transplantation reverses HRS2 in the majority of patients with survival outcomes comparable to matched controls, despite longer stays in intensive care unit and in hospital. Pretransplant HRS2 is associated with early posttransplant CKD3, despite calcineurin-inhibitor minimization.

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.
