Woman, 30, diagnosed with HIV eight years ago may be CURED of the virus despite not taking medication

• Doctors have named the unidentified Argentinian the ‘Esperanza Patient’
• She is the second recorded person to have naturally rid their body of the virus
• For the first eight years after being diagnosed she received no medication 

A woman who battled HIV for years is now clear of the virus despite not taking any medication, doctors have revealed today.

The unidentified 30-year-old, of Argentina, is only the second person ever recorded whose immune system has naturally rid their body of the virus.

The ‘Esperanza Patient’, as she is known, was first diagnosed with HIV in 2013 — but now has undetectable levels of the virus in her body.

For the first eight years after being diagnosed she received no medication except for six months when she was pregnant, to ensure her baby would be healthy. 

Researchers say the discovery brings a potential cure closer for the 38million people living with the AIDS-causing infection worldwide. 

The unidentified 30-year-old is only the second person ever recorded whose immune system has naturally rid their body of the virus. Only one other person has also naturally cleared the virus. Loreen Willenberg’s (pictured) story was first revealed last August. The 67-year-old, of San Francisco, was diagnosed with HIV 30 years ago.

In 1995, researchers discovered why HIV manages to come back even when it seems to have been defeated.

The virus buries part of itself in latent reservoirs of the body, lying dormant as ‘back-up’.

In 1996, it was discovered that anti-retroviral therapy (ART) could suppress the virus, and prevent it from resurging, if the medication was taken religiously.

But once that blanket is lifted, the virus swiftly rebuilds itself.

Despite decades of attempts, experts still don’t know how to get at those hidden parts of the virus.

The most promising approach may well be a ‘shock and kill’ technique – awakening the virus out of its hiding place then blitzing it.

But researchers don’t yet know how to wake it up without harming the patient.

A handful of HIV-infected patients who also had cancer have been left in long-term remission after undergoing a risky stem cell transplant.

The so-called ‘Berlin patient’ Timothy Ray Brown was the first to undergo the life-threatening procedure 13 years ago, which gave him a bone marrow transplant from a donor with HIV-resistant genes that wiped out his cancer and the virus in one fell swoop.

A group of Harvard-based medics announced the discovery at a major international meeting of HIV experts in March. 

Medics then revealed the patient, whose ex-boyfriend died of AIDS, had no disease-causing or ‘intact’ virus. 

The findings have now been confirmed in the Annals of Internal Medicine. 

Dr Xu Yu and colleagues found no intact traces of the virus in the 1.5billion blood and tissue cells they analysed. 

No other details of the woman are currently public but doctors at the time called her ‘athletic and beautiful’ and revealed she had a boyfriend and a newborn baby, both of whom were HIV-negative.  

Only one other person has also naturally cleared the virus. Loreen Willenberg’s story was first revealed last August. The 67-year-old, of San Francisco, was diagnosed with HIV 30 years ago. 

Academics claimed she could be ‘added to the list’ of cured HIV patients, next to the ‘Berlin patient’ Timothy Ray Brown and the ‘London patient’ Adam Castillejo.

Both Mr Brown and Mr Castillejo had cancer and received a bone marrow transplant from a donor with HIV-resistant genes to wipe out the disease and the AIDS-causing virus in one fell swoop.  

But neither Ms Willenberg — or the Esperanza patient — had the risky treatment.  

The two women are examples of elite controllers, a rare group of people who have never taken antiretroviral therapy but show no signs of the virus in their blood.

Normally, when a person gets infected with HIV, the virus attaches to their immune cell’s DNA and reproduces from there. 

Anti-retroviral therapy can help prevent the replication process but cannot eliminate HIV in the body altogether, meaning people need to take daily treatment to suppress the virus.

Adam Castillejo, 40, was the second person in the world to be cured of HIV. Earlier this year he revealed he was the ‘London patient’

‘Berlin Patient’ Timothy Ray Brown was successfully cured of the HIV virus 12 years ago

But for one in 200 people, the elite controllers, most of the virus settles into inactive parts of the genome, known as ‘gene deserts’, causing no harm. The remaining virus is cleared up by the body’s immune system.  

Dr Yu, based at the Massachusetts General Hospital, said: ‘These findings, especially with the identification of a second case, indicate there may be an actionable path to a sterilizing cure for people who are not able to do this on their own.

‘We are now looking toward the possibility of inducing this kind of immunity in persons on ART through vaccination, with the goal of educating their immune systems to be able to control the virus without ART.’

Writing in the journal Annals of Internal Medicine, the researchers added: ‘The person described here is originally from the city of Esperanza, Argentina.

‘In line with her wishes, we propose to refer to her as the “Esperanza patient” to send a message of hope for finding a cure for HIV infection.’
