Rare Disease Claims Young Boy's Life on Vacation
14 Jul
Summary
- A 5-year-old boy died from the extremely rare Clarkson's disease.
- Fewer than 500 cases of this capillary leak syndrome have ever been diagnosed.
- Family hopes to raise awareness to save future lives.

A family is speaking out after their young son succumbed to a devastatingly rare illness. Justin Vu, a vibrant 5-year-old, passed away on July 8, 2026, at Randall Children's Hospital in Portland, Oregon, just five days after falling ill during a family vacation.
Justin was visiting the Pacific Northwest with his mother, Terese Peden, and sisters when he began experiencing severe stomach pain and vomiting on July 3, 2026. Doctors initially suspected common ailments but his condition rapidly deteriorated, necessitating life support.
His father, Viet Vu, traveled from their Denver home as Justin was admitted to the intensive care unit. After extensive research, medical professionals identified the cause as Clarkson's disease, also known as systemic capillary leak syndrome. This rare condition causes plasma to leak from tiny blood vessels, potentially leading to organ failure and death if not promptly treated.
Despite the diagnosis, doctors were unable to save Justin. His parents made the difficult choice to move him to a hospital garden, where he passed away peacefully surrounded by loved ones. They are now advocating for greater awareness of Clarkson's disease, hoping his story can help save other lives.
