Subcutaneous administration of hepatitis B immune globulin in combination with lamivudine following orthotopic liver transplantation: effective prophylaxis against recurrence
Bibliographic record
Abstract
Prophylaxis against recurrent hepatitis B virus (HBV) infection with hepatitis B immune globulin (HBIG), in combination with antiviral agents such as lamivudine, has allowed transplantation for this condition to become feasible and accepted. Current protocols allow for HBIG administration either intravenously or intramuscularly. To date, there has been no reported experience with the subcutaneous route of post-transplant HBIG delivery. We report our experience of a 60-yr-old man for whom liver transplantation was performed for chronic HBV. HBIG was administered intramuscularly during the anhepatic phase of surgery. The finding of a portal vein thrombosis requiring repeated thrombectomy necessitated chronic anticoagulation. Post-operatively, HBIG was administered subcutaneously, in four separate injections, for a daily dose of 2170 IU along with continued lamivudine dosing. Hepatitis B surface antibody (anti-HBs) titres reached a serum concentration of >500 IU/L by seven d post-transplant and approximately 1000 IU/L by nine d post-transplant. Five months post-transplant, with continued combination of subcutaneous HBIG and lamivudine, there has been no recurrent HBV infection and anti-HBs titres have been at target levels. Our experience suggests that subcutaneous delivery of HBIG may be a feasible consideration when intramuscular/intravenous dosing is not possible.

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.
