Trending Now - Stem Cell Transplant From Brother May Have Cured HIV Patient

WHO:

Live Science - The patient, known as the "Oslo patient," is a 63-year-old man from Norway.

Live Science - Dr. Anders Eivind Myhre is a hematologist at Oslo University Hospital and a co-author of the study.

Live Science - Dr. Marius Trøseid is a group leader, professor, and infectious disease specialist at Oslo University Hospital and a co-author of the study.

WHAT:

Live Science - The Oslo patient is "likely cured" of HIV after receiving a stem cell transplant from his brother.

ScienceAlert - The patient has entered long-term remission from HIV, with no evidence of viral rebound at five years post-transplant.

Live Science - The patient was diagnosed with HIV in 2006 and started antiretroviral therapy (ART) in 2010.

Live Science - The patient was diagnosed with myelodysplastic syndrome in 2018, prompting the need for a bone marrow transplant.

ScienceAlert - The transplant was an allogeneic hematopoietic stem cell transplantation (HSCT).

WHERE:

Live Science - The treatment took place at Oslo University Hospital in Norway.

WHEN:

Live Science - The patient was diagnosed with HIV in 2006.

Live Science - The patient started ART in August 2010 and has maintained viral suppression since then.

Live Science - The patient was diagnosed with myelodysplastic syndrome in 2018.

Live Science - The stem cell transplant occurred in 2019.

ScienceAlert - The patient was cleared to stop ART two years after the transplant, which would be in 2021.

WHY:

Live Science - The transplant was initially sought to treat the patient's myelodysplastic syndrome, a type of bone marrow cancer.

HOW:

Live Science - The stem cell transplant involved infusing healthy, blood-making stem cells from the patient's brother, who carried the CCR5 delta 32 mutation, which makes him resistant to HIV.

Live Science - The patient's immune system was remodeled following the transplant, leading to the absence of HIV in his blood.

ScienceAlert - Follow-up tests showed that the transplanted immune cells had taken over, and HIV antibodies in the patient declined.

A 63-year-old man from Norway, known as the "Oslo patient," is now considered likely cured of HIV after receiving a stem cell transplant from his brother at Oslo University Hospital. Diagnosed with HIV in 2006 and myelodysplastic syndrome in 2018, he underwent the transplant in 2019, which involved infusing stem cells that are resistant to HIV, leading to long-term remission with no signs of viral rebound. Follow-up tests have confirmed that his immune system has been successfully remodeled, resulting in a significant decline in HIV antibodies.
