The world is closer to finding a cure after an HIV infected child treated early achieved remission. The nine-year-old, whose identity has been withheld to protect her and her family, Gay rse play history recently when she proved to be the first child participating in an early antiretroviral ARV therapy trial to control HIV after stopping treatment. Before starting the treatment, the child had a high viral load, but, at about nine weeks old, the ARVs had suppressed the virus to undetectable levels. Ten months after starting treatment, the treatment was stopped and her immunity was closely monitored. Caroline Alter a asset sensitive, the senior author of this case and research professor in virology in the Cure hiv hope valproic of Pathology at Wits, who led the key laboratory investigations, said the child had remained in good health during years of follow-up examinations. However, this was not the first time that an HIV-infected child who Cure hiv hope valproic treated early on achieved remission. Ina baby in Pix of men riding bike shirtless received ARVs 30 hours after birth and stopped therapy at around 18 months of age. While the child managed to control the virus without drugs for 27 months, it then reappeared in her blood. Inresearchers reported that another child — born with HIV in — who started anti-HIV therapy at the age of three months and stopped treatment Cure hiv hope valproic between the ages of five and seven, had continued to control the virus without drugs more than 11 years later.

A recent publication in Lancet by Dr. David Margolis and colleagues raised the prospect that HIV infection may be curable. In this pilot study, which received much attention from the press, Dr. This commentary critically addresses current data on this topic. A recent publication in Lancet [ 1 ] has created quite a stir among HIV circles no, not those containing 1 or 2-LTRs [ 2 ] and the lay press. In a study led by Dr. This pool of cells — often referred to as the viral reservoir — is thought to pose an significant obstacle to HIV eradication. This pool of cells is also thought to serve as a biological library for archival strains of drug-resistant HIV [ 4 ]. Even years after discontinuation of a given drug, resistant strains of HIV-1 quickly re-emerge when the drug is re-introduced into a therapeutic regimen. Therefore, in theory, a treatment protocol that reduces or eliminates this pool of infected cells could eliminate drug-resistant strains, and would have the potential to cure HIV infection. Siliciano and colleagues estimate the mean time to eradication is The stimulatory effect of VPA is equal to, or greater than, that of the mitogen, PHA, but VPA has no effect on T-cell activation or virus production from mitogen-activated lymphoblasts. In the Lancet study, four patients with long-term, undetectable viremia were given enfuvirtide, an injectable HIV fusion inhibitor, added to their ongoing regimens. After 4—6 weeks, VPA was then started. The results of this pilot study are intriguing, but must be considered cautiously with a clear understanding of their inherent limitations. At least one group has demonstrated that intensification of anti-HIV therapy decreases the half-life of this population [ 7 ]. This study also raises important issues regarding the use of enfuvirtide in an intensification regimen....

Terms of use and Your privacy. This theory was based on the assumption that all HIV-infected cells in the body are short lived and that combination antiretroviral therapy likely had the potency to snuff out viral replication completely. In , the publication of three additional papers threw a wet towel on the hope stemming from the findings. Based on these and other observations, researchers have looked into ways to activate these long-lived resting cells so that standard antiretroviral therapy can get to the virus and stop it from replicating. A likely explanation for this is the fact that activation not only induced viral replication, it also increased the number of susceptible uninfected cells beyond the threshold that can be protected by antiretroviral therapy. What was needed, it seemed, was a drug capable of inducing the expression of HIV hiding within these cells, while simultaneously limiting any activation of immune system cells. One such approach that has gained a lot of attention in recent years is the inhibition of histone deacetylase HDAC , an enzyme believed to play a key role in maintaining HIV inside long-lived resting cells. In , it was determined that valproic acid — a medication commonly used to manage seizures, migraines, and bipolar disorder — is an inhibitor of HDAC, a finding that has resulted in great interest among researchers on the HIV eradication trail. This was followed by another paper in , authored by David Margolis, MD, of the University of North Carolina, Chapel Hill, and his colleagues, reporting on study results involving four HIV-positive patients receiving three months of valproic acid in combination with their antiretroviral drug regimens. In short, the study found that levels of HIV inside the quiescent cell population decreased dramatically. Two years later, a new paper published by Janet Siliciano, PhD,...

Remission refers to a state following treatment that is then stopped. The South African case - the first reported instance of HIV remission in an African child, and only the third case in the world - has raised many questions about what makes this child so unique. Is it the virus? Is it the host? Were the drugs essential to this outcome? I am part of a team of researchers that is investigating this unusual case, an endeavour that has intensified this year. What we found were signs that HIV can be suppressed naturally for a long time after someone has been on a short spell of treatment. The discovery is only the first bit of a puzzle we are piecing together - on an ongoing basis - into what exactly causes suppression. It opens the door for researchers to establish how to make long-term remission possible for other people. This is a critical part of making HIV a manageable disease. The child - whose gender has not been disclosed - was born in to an HIV-positive mother. The trial ran from to The child started anti-retrovirals just after turning 2 months old. The child was one of babies who received early treatment for 40 weeks. The virus rebounds within weeks in most people who stop taking the drugs. The child had high levels of the virus in the blood before starting treatment at two-and-a-half months. This suggested that the child had an actively replicating virus at the time. But by the time the child was 9, there were only small traces of virus in the cells and the virus was no longer actively replicating. Understanding both the response now - and which immune responses were initially involved - is critical to help us develop a vaccine, or other...

Margolis began his October lecture with a crucial question. Margolis, continued momentum toward the eradication of infection. Early treatment, intensified treatment regimens, and immune-based therapies to achieve this goal have all been pursued—with limited success—and discussed in detail over the past ten years. Just as it seemed as if the possibility of eradicating HIV was nothing more than a pipe dream, exciting new research has emerged—utilizing a truly novel approach and exploiting a very common compound—bringing the possibility of a cure to the forefront once again. The compound in question is valproic acid, best known as Depakote, a tried and true treatment for bipolar disorder and epilepsy. The property of valproic acid exploited in the current approach is its known ability to inhibit histone deacetylases, enzymes that evidently maintain the integrated and latent HIV quiescent in the host genome. Although still in its infancy, the early work of Dr. Margolis and his colleagues has opened an exciting new avenue of research for the potential eradication of HIV. PRN was pleased to host Dr. Margolis at its October meeting to explain the theory behind, and the data supporting, continued evaluation of this approach. Employing antiretroviral therapy, these teams demonstrated that levels of HIV-RNA in plasma dropped by half approximately every 48 hours, signifying that enormous numbers of virions are produced by infected cells with relatively short life spans. Subsequent experiments documented the existence of a second, much slower phase of HIV clearance in plasma during therapy; this second phase was associated with the suppression of viral replication in long-lived cells in tissue. Simple mathematical modeling suggested that all cells harboring the virus would die off within about three years of maximally suppressive therapy, thereby raising the possibility of complete eradication of HIV from the human host. The successful realization of this...
