STORY SUMMARY
Taiwan, known for its high prevalence of dialysis patients, is exploring advanced solutions to its organ shortage crisis through xenotransplantation. According to the Taiwan Society of Nephrology, about 96,000 patients with end-stage kidney disease are currently on dialysis, many awaiting transplants. Chen Yen CH, Director of the Organ Transplantation Center at Juan SI Hospital, highlighted the potential of genetically modified pig kidneys, which have reached the clinical research stage. This technique involves editing around 10 pig kidney genes to make them compatible with human bodies, reducing the risk of rejection. In the US, two successful pig kidney transplants have shown promising recovery of kidney function. However, urologist Yang Re emphasized ongoing challenges, including species-specific rejection and the risks of bacterial and viral infections. Apart from the medical hurdles, ethical concerns regarding animal welfare also persist. Despite these challenges, xenotransplantation presents a hopeful avenue, necessitating further research and dialogue to ensure both medical efficacy and ethical integrity.

FULL STORY
Taiwan is grappling with a significant shortage of organs for transplantation, primarily due to the high number of kidney disease patients in need. According to the Taiwan Society of Nephrology, as of 2023, around 96,000 people with end-stage kidney disease in Taiwan are dependent on dialysis. A growing number are also awaiting kidney transplants. Xenotransplantation, particularly utilizing genetically edited pig kidneys, is emerging as a potential solution to this crisis, as highlighted by Chen Yen-chih, director of the Organ Transplantation Center at Huan Sin Hospital.
Research in the field of xenotransplantation has advanced to the clinical stage, focusing on editing approximately 10 genes in pig kidneys to make them viable for human transplantation without causing rejection. In the United States, there have been reports of two successful pig kidney transplants demonstrating good postoperative recovery of kidney function. Despite these successes, significant challenges remain, as pointed out by urologist Yang Re. The primary concerns include the human body’s potential to reject pig kidneys due to species differences, and the risks associated with bacterial and viral infections.
Moreover, the prospect of xenotransplantation raises ethical issues concerning animal welfare. While this innovative approach shows promise in addressing organ scarcity, it necessitates thorough research and open communication to ensure adherence to both medical safety standards and ethical considerations. The progress in this field is being closely monitored, as it could be pivotal in resolving the organ shortage crisis that Taiwan and many other countries face.
