British Man Becomes Only Second-Ever Patient To Be 'Cured' Of HIV

News |


The male patient has remained anonymous, being referred to simply as 'The London Patient'. In 2003, he was diagnosed with HIV infection and developed a cancer, advanced Hodgkin's Lymphoma, in 2012. In 2016, he received a transplant of haematopoietic stem cells from a donor carrying a genetic mutation in the HIV receptor CCR5, which hinders the HIV virus from entering human cells.

He has now been in remission for 18 months after his antiretroviral drugs were discontinued, researchers said.

While it is too premature to say with certainty that our patient is now cured of HIV, he is clearly in a long-term remission. We continue to monitor his condition; however, the apparent success of this treatment injects new hope in the search for a long-awaited cure for HIV/Aids.

According to the ABC, highly sensitive tests have since shown that there is now no HIV detected in his system. HIV biologist who co-led a team of doctors treating the man, Ravindra Gupta, said that it's too early to say whether he is officially cured of the disease, but did go as far as saying that the patient was 'functionally cured' and 'in remission'.

It was only in 2016 that he was able to access the stem cell donation because he was seeking treatment for the cancer, not the HIB. Doctors haven't been clear on why the patient hadn't started ART when he was diagnosed with the disease.

The donor had genetic mutation known as CCR5 delta 32, a gene that provides a resistance against HIV.

Clarifying the matter to the Daily Mail, Dr Anthony Fauci, head of the HIV/AIDS division at the National Institutes of Health, told the newspaper that we shouldn't expect this stem cell type of treatment to become the standard for people wanting a cure for the condition. He pointed out that The London Patient's case were pretty unique due to his personal circumstances:

"If I have Hodgkin's disease or myeloid leukemia," he said, "that's going to kill me anyway, and I need to have a stem cell transplant, and I also happen to have HIV, then this is very interesting.

"But this is not applicable to the millions of people who don't need a stem cell transplant."

The unidentified man now joins Timothy Ray Brown, also known as The Berlin Patient, the only other person to be cured of HIV.

He was diagnosed with the disease in 1995 and started antiretroviral treatment. The American was afflicted with acute myeloid leukemia and received a stem cell transplant from a donor with the same CCR5 delta 32 gene.

Three months after his first treatment, the HIV in his body dropped dramatically and he was soon listed as undetectable. He still doesn't take antiretroviral treatment, and yet he remains essentially cured.

While individual cases like these don't yet mean a cure for HIV worldwide, it certainly gives us hope that we can arrive at that in the foreseeable future.
