Hopes High for HIV vaccine trial in South Africa

2018-07-24T14:18:58+00:00

The latest attempt in the long, frustrating search for a vaccine against HIV began in South Africa on Wednesday, as scientists test a beefed-up version of the only shot ever to show a glimmer of protection. The stakes are high. It’s the first study of its kind begun in seven years, and even moderate success could prove important not only in hard-hit South Africa, where more than 1,000 people a day are infected with HIV, but beyond. “If an HIV vaccine were found to work in South Africa, it could dramatically alter the course of the pandemic,” Glenda Gray, president of [...]

Dashboard will speed up SA’s HIV suppression objectives

2018-07-24T14:19:23+00:00

Now, healthcare practitioners involved in managing South Africa's HIV pandemic can access data from a new web-based system in near real-time. The first national CD4 /viral load monitoring dashboard, an online tool that monitors CD4 count and viral load in South Africa’s HIV positive patients will help the country to achieve one of UNAIDS three HIV elimination targets: for 90% of people on treatment to have a viral load fully suppressed by 2020, Response to treatment Viral load is the best predictor of an HIV positive patient’s response to treatment. The dashboard displays and analyses data in a way in which [...]

Undetectable viral loads maintained with experimental therapy

2018-07-24T14:22:03+00:00

An experimental ‘four days on, three days off’ antiretroviral regimen kept viral load fully suppressed in 96% of people for 48 weeks in a French study presented recently at the International Congress on Drug Therapy in HIV Infection (HIV Glasgow). The study recruited people whose viral load had been fully suppressed on treatment for a median of four years, not people who had started treatment recently. Although people living with HIV are recommended to take antiretroviral drugs every day as prescribed, there is evidence from therapeutic drug monitoring that sufficient blood levels of many antiretroviral drugs persist for several days after [...]

British Scientists May Have Just Cured the First Person Ever of HIV

2018-07-24T14:23:37+00:00

A 44-year-old British man is the first of 50 people to complete a trial of a treatment which scientists say eradicates HIV cells in the entire body––including dormant cells which evade current HIV treatments. Doctors declined to identify the patient, who is a social care worker in London. “It would be great if a cure has happened. My last blood test was a couple of weeks ago and there is no detectable virus. I took part in the trial to help others as well as myself,” he said. “It would be a massive achievement if, after all these years, something is found to [...]

Acclaimed HIV/Aids expert Professor Salim Abdool Karim said that the human studies will start in the middle of next year following promising results when the antibody from the 27-year-old KZN woman was successfully tested on monkeys. The mother of two – known as CAP 256 to protect her identity – tested HIV-positive in 2005. “We have taken the antibody [...]

Until now, experts were aware only of cases in which men spread the virus to their partners during sex, as well as transmission by mosquito bites. The New York case involved a "nonpregnant woman in her twenties who reported she had engaged in a single event of condomless vaginal intercourse with a male partner the day she returned to New York City from travel [...]

Over 95 percent of these deaths occur in developing countries, which is exacerbated by difficulties in diagnosing the disease based on signs and symptoms. A new point-of-care test aimed at use in areas of limited resources could help speed up the diagnosis and spread of TB. The new test is being developed by an international team of researchers led by researchers at Stellenbosch University in South Africa. To [...]

The new study, called HVTN 702, is designed to determine whether the regimen is safe, tolerable and effective at preventing HIV infection among South African adults. It will use a new variation of the RV144 shot, an experimental HIV vaccine developed by the US's National Institute of Allergy and Infectious Diseases (Niaid). The drug will be trialled in South Africa at the end of 2016. The HVTN [...]
