Is An Hiv Cure Possible
Researchers remain hopeful that they’re heading in the right direction to finding a cure for HIV, the virus that causes AIDS. Right now, itâs still out of reach. But the unusual cases of four people may hold clues.
The latest case is a 30-year-old woman in Argentina whose name hasnât been made public. She had HIV, but for 8 years, it has been âundetectableâ in her body, though she didnât take antiretroviral medication, researchers reported in the Annals of Internal Medicine in November 2021. Scientists donât know exactly how that works and canât say for sure that she is cured. But they wrote in the study that cases like the Argentinian womanâs may be âextremely rare but possible.â
Perhaps the best known is the âBerlin patient,â Timothy Ray Brown. Heâs the first person ever to be cured of HIV. Brown found out in 2006 that he had acute myeloid leukemia. He already knew he had HIV and had been taking medicine for it for years.
After chemotherapy didnât help his leukemia, Brown went to Berlin, where he got two bone marrow transplants from an HIV-resistant donor. Ten years later, Brown is leukemia- and HIV-free. Other HIV-positive leukemia patients who got similar treatments havenât been free of HIV. Experts still donât know why Brown became free of HIV.
How Close Are We To A Cure For Hiv/aids
CHARLOTTE, N.C. â Last month, a woman from Argentina was documented as one of the first few people to be cured of HIV, and Spectrum News 1 looked into how close we are to finding a cure on a large scale.

Is An Hiv Cure Possible The Future Of Hiv Therapy
HIV research has come a long way since the virus was discovered in the 1980s. Antiretroviral therapy was a major milestone that has changed the lives of millions the goal now is to find an HIV cure.
Back in 2008, Timothy Ray Brown was the first person to be cured of HIV. Known as the Berlin patient, he received two bone marrow transplants from a donor who was naturally resistant to HIV to treat his leukemia. He remained off antiretroviral therapy until his death in 2020.
When the case was announced, the medical world went nuts. Had we finally achieved an HIV cure?
Unfortunately, the answer remains not yet. Since then only one other person, the London patient, has been reported to remain off antiretroviral therapy thanks to a similar transplant. However, bone marrow transplants carry very high risks for HIV-positive patients, and HIV-resistant donors are rare.
These cases have been an inspiration for researchers to find better alternatives against HIV. In recent times, one of the main accomplishments has been the approval of long-lasting antiretroviral treatments that are taken every one or two months instead of daily.
There are multiple promising approaches currently in research and development to achieve a functional cure one that leaves people living with HIV healthy and medication-free without necessarily wiping the virus completely.

Why Is Hiv So Difficult To Cure
When the highly effective combination antiretroviral treatment for HIV arrived in 1996, Dr. David Ho, who was one of the architects of this therapeutic revolution and is the director of the Aaron Diamond AIDS Research Center in New York City, famously theorized that given enough time, such medications could eventually eradicate the virus from the body.
To date, there are a handful of cases of people who were started on antiretrovirals very soon after contracting HIV, later went off treatment and have remained in viral remission with no rebounding virus for years.
Otherwise, Hos prediction has proved false. During the past quarter century, HIV-cure researchers have learned in increasingly exacting detail what a daunting task it is not only to cure HIV, but to develop effective curative therapies that are safe and scalable.
HIV maintains such a permanent presence in the body because shortly after infection, the virus splices its genetic code into long-lived immune cells that will enter a resting state meaning they stop churning out new viral copies. Antiretrovirals only work on replicating cells, so HIV can remain under the radar of such medications in resting cells for extended periods, sometimes years. Absent any HIV treatment, such cells may restart their engines at any time and repopulate the body with massive amounts of virus.
Timothy Browns case, , ignited the HIV-cure research field, which has seen soaring financial investment since.
Progress In Preventing Hiv Infection
PrEP is a regimen of antiretroviral drugs given before an individual is infected with HIV that is designed to protect people at risk. When used as recommended, it can dramatically reduce transmission risk. But it appears to be more effective at preventing HIV in men who have sex with men than in heterosexual womena group of individuals who are also at risk, especially in sub-Saharan Africa.
Roans lab is studying the factors that may be responsible for the difference.
We are trying to understand what happens during the earliest of events when the female reproductive tract is exposed to HIV, she says. Historically, both in the HIV cure and prevention areas, most studies have focused on men. We really need more effective ways that can prevent transmission and cure HIV for the entire population at risk.

A Woman Has Been Cured Of Hiv Using A Groundbreaking Umbilical Cord Blood Transplant Scientists Say
- A woman has reportedly been “cured” of HIV, using a novel technique involving newborn blood.
- The technique is seemingly gentler than stem-cell transplantation, the only known way that people have been cured before of the virus that causes AIDS.
An HIV-positive woman appears to have been cured of the virus, using an unusual, and seemingly far more gentle transplantation technique than ever before, which involved umbilical cord blood sourced from a newborn.
Details of her case, announced at the Conference on Retroviruses and Opportunistic Infections Tuesday, were first reported in The New York Times.
“This case is the first to use cord blood cells, and the first to treat a woman and someone who identifies as mixed-race,” Weill Cornell Medicine, the institution where the patient was treated, told Insider in a statement.
The umbilical cord blood recipient received her blood transplant in August 2017, from a donor with a genetic mutation that blocks HIV. That mutation is far more common in people of European heritage, which can make it hard to find well-matched stem-cell transplant donors for non-white patients.
The new case suggests hope that more patients of diverse backgrounds may be able to receive stem-cell transplants in the future, though experts stress the treatment isn’t likely to become commonplace for HIV.

Does Hiv Go Away
The HIV virus is still in existence, but there are very effective drug treatments that can allow virtually everyone living with HIV to live a long and healthy life without having to worry about AIDS-related illnesses. Through proper diagnosis and treatment, most people with HIV will not develop any AIDS-related illnesses
Will There Ever Be A Cure For Hiv
Researchers and scientists believe we can find a cure for HIV. We know a lot about HIV, as much as certain cancers. Scientists are researching two types of cure: a functional cure and a sterilising cure.
There is no ‘natural cure’ or ‘herbal cure’ for HIV. Antiretroviral treatment is the only medication that is proven to effectively control HIV.

First Woman Reported Cured Of Hiv After Stem Cell Transplant Know Details
A leukaemia patient in the US has become the first woman and the third person to be cured of HIV, the virus that causes AIDS, after receiving a stem cell transplant, according to researchers.
In a presentation at Conference on Retroviruses and Opportunistic Infections in the US on Tuesday, the researchers reported that the woman has had no detectable levels of HIV for 14 months despite cessation of antiretroviral therapy .Stem cells have the unique ability to develop into specialised cell types in the body.
This is the third known case of HIV remission in an individual who received a stem cell transplant, the National Institutes of Health said in a statement.
HIV remission resulting from a stem cell transplant had been previously observed in two cases.
The first, a Caucasian male, known as the “Berlin patient”, experienced HIV remission for 12 years and was deemed cured of HIV. He died of leukaemia in September 2020.
A Latino male called the “London patient” has been in HIV remission for more than 30 months.
This third case suggests that cord stem cell transplantation should be considered to achieve HIV remission and cure for people living with HIV who require such a transplant for other diseases, the study team said in the statement.
The research was conducted by the International Maternal Pediatric Adolescent AIDS Clinical Trial Network P1107 observational study led by researchers at the University of California Los Angeles, and Johns Hopkins University.
Promising New Research May Soon Help Treat And One Day Cure The Chronic Disease
Just over a decade ago, researchers announced a first: They had cured a patient of HIV. Known as the Berlin patient, Timothy Ray Brown had needed a bone marrow transplant to treat his acute myeloid leukemia. Doctors used the opportunity to replace his bone marrow using stem cells from a donor with gene-based HIV immunity. It worked: Browns leukemia was cured, as was his HIV. More recently, in 2019, a second patient, this time being treated for Hodgkins lymphoma, was similarly cured in London.
But although these are the most famous stories where patients have been cured from HIV, their treatments represent just one option of many new approaches for tackling the virus and one of the least widely applicable. Its too invasive and too risky to conduct a bone marrow transplant on someone who doesnt already have cancer that requires the procedure especially considering most patients with an HIV diagnosis and access to care can effectively control the disease with drugs. In fact, a patient on antiretroviral therapy, or ART, today has the same life expectancy as a person without HIV.

Is There A Cure For Hiv And Aids
There is no cure for HIV, although antiretroviral treatment can control the virus, meaning that people with HIV can live long and healthy lives.
Most research is looking for a functional cure where HIV is permanently reduced to undetectable and harmless levels in the body, but some residual virus may remain.
Other research is looking for a sterilising cure where HIV is removed from the body completely, but this is more complicated and risky.
Trials of HIV vaccines are encouraging, but so far only offer partial protection.
There is no cure for HIV yet. However, antiretroviral treatment can control HIV and allow people to live a long and healthy life.
For some people, treatment can reduce the level of HIV in their body to such a low amount that they are unable to pass it on . Having an undetectable viral load can keep you healthy, but its not a cure for HIV. To maintain an undetectable viral load a person must keep adhering to their antiretroviral treatment.
The Challenge Of The Replication Cycle
Instead of being able to focus on a single strain of HIV, researchers have to account for the fact that it replicates so quickly, which can cause mutations and new strains. The replication cycle of HIV takes a little more than 24 hours.
And while the replication process is fast, it’s not the most accurateproducing many mutated copies each time, which then combine to form new strains as the virus is transmitted between different people.
For example, in HIV-1 , there are 13 distinct subtypes and sub-subtypes that are linked geographically, with 15% to 20% variation within subtypes and variations of up to 35% between subtypes.
Not only is this a challenge in creating a vaccine, but also because some of the mutated strains are resistant to ART, meaning that some people have more aggressive mutations of the virus.

What Are The Chances Of Surviving Hiv
Survival rates for HIV patients after diagnosis to AIDS ranged from 89 percent to 69% and from 30 percent to 30 percent over the following five years. Survival rates from AIDS to death ranged from 76% to 46% in one year and from 46% to 46% in five years. In the first year, five years, and ten years after HIV diagnosis, 87%, 67%, and 40%, respectively, of patients survived.
Meet The First Woman To Be Cured Of Hiv
An American research team used a novel stem cell transplant treatment to cure HIV in the woman in question. The first public instance of someone being cured of HIV this way was Timothy Ray Brown in 2008, who received a stem cell transplant from a donor with a natural genetic resistance to the virus. Scientists hope to expand the treatment to several dozen patients every year.
- The treatment aims to replace the patient’s immune system with one that has this natural HIV resistance, but it means first destroying the patient’s immune system a highly risky proposition.
- Because destroying the immune system requires chemotherapy and radiation, it has only been used to treat patients with both cancer and HIV.
- The same treatment has since cured HIV in two other people, though it has failed to produce the same result among other patients.

A patient living with HIV who received a blood stem cell transplant for high-risk acute myeloid leukemia has been free of the virus for 14 months after stopping HIV antiretroviral drug treatment, suggesting a cure, according to the Weill Cornell Medicine physician-scientists who performed the transplant and managed her care. As in two other successful cases that have been reported, the transplanted donor cells bore a mutation that makes them resistant to HIV infection.
The new case of long-term HIV remission was reported on Feb. 15 at the 29th annual Conference on Retroviruses and Opportunistic Infections, in Denver.
The patient received transplants of blood- and immune-cell replenishing stem cells after having her own blood cell population, including leukemic cells, destroyed by high-dose chemotherapy. The transplanted cells came from two sources: stem cells from a healthy adult relative were used to quickly restore her blood cell population to reduce infectious complications, and umbilical cord blood from an unrelated newborn child was used to provide long-term blood reconstitution.
Have There Been Any Breakthroughs
One reason to hope for a cure for HIV is that experimental treatments seem to have worked in a handful of people already.
The Berlin Patient: In 2008, a man with HIV named Timothy Ray Brown was effectively cured while living in Germany. Researchers treated his blood with a stem cell transplant for leukemia, but the treatment also cured his HIV. His stem cell donor carried a mutation of an HIV-related gene called CCR5. This mutation makes a person almost completely resistant to infection. Brown was the only person to be cured of HIV until 2019, when two others were effectively cured with a similar stem cell therapy.
Visconti Cohort: In 2010, a baby born with HIV in Mississippi began ART soon after birth and was in remission for 2 years after they stopped, but the virus did come back. A trial called the Visconti Cohort studied 20 people with HIV in France. They also started ART within weeks of infection. They were able to stop taking the drugs and still have low levels of HIV years later. Another trial of 15 children with HIV in Thailand had similar results. Itâs important to remember that these were controlled studies if you have HIV, you should never stop ART without talking to your doctor.
These are positive signs, but the studies are very small. We need more research on these potential cures to be able to develop treatments that would safely work on many people, not just a small number.
