HIV: An exceptional remission achieved after an unexpected transplant

A Norwegian patient with HIV is now in remission after an extraordinary medical journey involving treatment for blood cancer and a genetic coincidence. Diagnosed HIV-positive in 2006 and then with myelodysplastic syndrome in 2017, this man received a bone marrow transplant in 2020 which led to the virus disappearing from his body, according to a recent scientific study.

The procedure, initially intended to treat his cancer, involved a stem cell transplant. Lacking an identified donor carrying a specific genetic mutation known to block HIV, the doctors turned to his brother. It was only at the time of the transplant that they discovered he possessed this rare mutation, present in approximately 1% of the population in certain regions.

A very rare case with scientific lessons to be learned

After the operation, the patient's condition improved dramatically. Two years later, doctors were able to discontinue his antiretroviral treatment, with no trace of the virus detected in his blood or other tissues. Now 63 years old, he no longer shows any signs of infection and leads a normal life, according to the researchers involved in his follow-up.

This type of remission remains extremely rare and is not a universally applicable solution. Bone marrow transplantation is a complex and risky procedure, reserved for serious medical cases such as certain cancers. Nevertheless, these exceptional situations allow scientists to better understand the mechanisms of HIV and could, in time, inspire new therapeutic approaches.
