Human immunodeficiency virus activity in rib allografts
Summary
Human immunodeficiency virus (HIV) activity persists in ribs from acquired immune deficiency syndrome (AIDS) patients even after freezing and thawing. Donor screening is crucial for safe bone allograft use.
Area of Science:
- Virology
- Immunology
- Orthopedic Surgery
Background:
- Bone allografts carry a risk of infectious agent transmission.
- Historical data highlights the potential for disease transmission from donors to recipients.
Purpose of the Study:
- To investigate if human immunodeficiency virus (HIV) remains active in rib bone allografts after cryopreservation.
- To test the hypothesis that freezing and thawing do not eliminate HIV from infected bone tissue.
Main Methods:
- Rib samples from an autopsy of an acquired immune deficiency syndrome (AIDS) patient were collected under sterile conditions.
- Samples were frozen at -80°C for varying durations.
- Cultured with activated lymphocytes to assess viral activity via P24 antigen detection.
Main Results:
- Viral activity was confirmed in rib samples subjected to freezing periods ranging from 1 to 12 weeks.
- HIV demonstrated resilience to cryopreservation methods used in bone banking.
Conclusions:
- Human immunodeficiency virus (HIV) activity can persist in bone allografts from acquired immune deficiency syndrome (AIDS) patients.
- Cryopreservation does not inactivate HIV in bone tissue, underscoring the importance of donor selection.
- Rigorous donor screening remains the primary safety measure for frozen bone allografts.
