Key MechanismsAdoptive transfer of BKV-specific T cells using the CliniMACS Prodigy system to combat viral reactivation.
Target Population
Care Setting

Key Highlights

  • BKV reactivation occurs in up to 81% of allogeneic stem cell transplant recipients, with significant clinical implications.
  • Adoptive transfer of BKV-specific T cells showed a decrease in viral load in 3 out of 4 patients, with specific patient outcomes detailed.
  • Treatment was well tolerated with no severe adverse effects reported, emphasizing safety.

Guideline-Based Recommendations

Diagnosis

    Management

    • Utilize supportive care including hydration, tranexamic acid, and ciprofloxacin, with specific dosages if available.
    • Consider BKV-specific T cell therapy for refractory cases, detailing criteria for selection.

    Monitoring & Follow-up

      Risks

        Patient & Prescribing Data

        Pediatric patients with severe BKV infections post-transplant.

        BKV-specific T cells may provide a novel therapeutic option for refractory infections.

        Clinical Best Practices

        • Prompt administration of BKV-specific T cells may enhance efficacy; provide evidence or rationale.
        • Minimize concurrent immunosuppression to improve treatment outcomes, explaining the mechanism.
