A young south-eastern Louisiana man recently became the first person in his region to be functionally cured of sickle cell disease, clearing the way for him to continue pursuing his dream of a career as a commercial pilot, according to his medical team.

Daniel Cressy’s successful completion of curative gene therapy at Manning Family Children’s hospital in New Orleans on Monday generated a measure of optimism within his state, which produces more cases of sickle cell disease per capita than any other in the US, according to the medical center.

A statement attributed to Cressy, 23, said his story embodied “overcoming what seemed impossible” – and hoped it would be “inspirational for a lot of people”.
