Use of Tumor Necrosis Factor-α-blocking Agents in Hepatitis B Virus-positive Patients: Reports of 3 Cases and Review of the Literature
Bibliographic record
Abstract
OBJECTIVE: To evaluate the development of hepatitis B virus (HBV) infection in patients receiving tumor necrosis factor-alpha-blocking agents (TNFBA), and to evaluate whether lamivudine (LAM) prophylaxis can reduce the risk of viral reactivation in inactive HBsAg carriers. METHODS: Local experience and published reports were reviewed. Patients with HBV infection were classified as having chronic HBV hepatitis, or being inactive HBsAg carriers or occult carriers. RESULTS: Three patients in our series and 24 patients in the literature were identified: 2 had active HBV-associated disease, 23 were inactive HBsAg carriers, and 2 occult carriers. When exposed to TNFBA, HBsAg-inactive carriers pretreated with LAM had lower risk of having detectable HBV-DNA (p=0.02) or viral reactivation (p=0.046) than those without LAM prophylaxis. In 3 patients who discontinued TNFBA, LAM prophylaxis was also discontinued 10-12 months thereafter without hepatitis flares. Two cases of reactivation in occult carriers (HBsAg-negative, anti-HBs+, anti-HBc+) were described in the literature. CONCLUSION: TNFBA should be avoided in patients with active HBV replication and should be used with caution in inactive HBsAg carriers. In these patients, the risk of viral reactivation seems to be high, but it might be reduced by prophylactic LAM, which should probably be given for a long time when TNFBA are discontinued (e.g., 12 mo). Potential occult carriers might carry a low, but not negligible, risk of viral reactivation. They should therefore be monitored with particular care.

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.
