Utilization of a Liver Allograft from a Hepatitis B Surface Antigen Positive Donor
Bibliographic record
Abstract
With today's donor organ shortage, enhanced efforts must be made to utilize organs that previously would have been declined. We report a 26-year-old man with chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) coinfection who received a liver transplant from an HBsAg-positive donor. HBV viremia (6,281,185 copies/ml) was seen early posttransplant despite lamivudine prophylaxis, but became negative with addition of adefovir. Virologic analysis revealed predominantly donor HBV strain immediately posttransplant. At 5 months there was an elevation of liver enzymes accompanied by histologic evidence of hepatitis. At this time, HCV-RNA was positive but HBV DNA was undetectable. Treatment with pegylated interferon and ribavirin resulted in sustained clearance of HCV RNA. Two years posttransplant, the patient has normal liver biochemistry and HCV and HBV viral load are undetectable with persistence of HBsAg. Our experience suggests that with effective antiviral therapy, the use of HBsAg seropositive donors is feasible in selected circumstances.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
