Existing Ethical Tensions in Xenotransplantation.

Area of Science:

• Medical Ethics
• Transplantation Biology
• Animal Welfare Science

Background:

• Chronic organ shortages necessitate innovative solutions.
• Xenotransplantation (XTx) using genetically modified pigs is explored as a potential solution.
• Existing ethical frameworks present significant challenges to XTx implementation.

Purpose of the Study:

• To identify and describe the ethical tensions surrounding xenotransplantation.
• To analyze the conflicts between XTx requirements and established ethical principles.
• To provide a basis for ethical deliberation on the future of XTx.

Main Methods:

• Ethical analysis of xenotransplantation protocols.
• Review of existing ethical guidelines and principles in human research and transplantation.
• Examination of animal welfare concerns in the context of organ procurement.

Main Results:

• Lifelong surveillance and contact notification conflict with human research subject rights.
• Pediatric consent for xenografts challenges a child's right to an open future.
• Public health risks (zoonotic diseases) conflict with individual consent and animal welfare.

Conclusions:

• Xenotransplantation raises profound ethical questions regarding patient autonomy, public health, and justice.
• Animal welfare is compromised by necessary disease prevention measures for source animals.
• The ethical complexities of XTx necessitate careful consideration and may argue against its pursuit.
