    Cure in sight for HIV infection
    Scientists have found a way of eradicating HIV infection from the human body by “smoking” out the virus from its hideout cells. The new approach is to kill the hideout cells plus the virus.

    The current anti-Aids drugs only destroy viruses circulating in the body but some manage to hide in particular immune system cells and continue replicating, hence the patient has to remain on medication throughout.

    The new development by a team of American and Canadian researchers is the second indication that a cure for the disease that continues to afflict more than 1.3 million Kenyans and many more globally may finally be within reach.

    In February, researchers in California developed a gene therapy with the capacity of eradicate HIV from the body and have since put 12 people on clinical trials. The study is still ongoing though it is said to involve a complex process that could make it very expensive.

    Radical new therapy

    Published on Sunday in the Nature Medicine journal, the new study says HIV and Aids can be treated through a combination of targeted drugs together with current anti-retrovirals.

    “This radical new therapy would make it possible to destroy both the viruses circulating in the body as well as those playing hide-and-seek in immune system cells,” says Dr Rafick-Pierre Sékaly, of the University of Montreal, Canada.

    Other participating groups included the universities of McGill and Minnesota and the National Institutes of Health, the latter is the US federal agency responsible for overseeing government-sponsored biomedical research.

    Current anti-retroviral treatments are not able to eradicate the virus from the body because some disease agents hide in particular cells where the existing treatments cannot reach. These researchers have now identified these cells and found a way of reaching them.

    The new approach, says the team, is to use drugs to kill the cell containing the virus while giving the immune system time to regenerate with new cells. This could much cheaper that the gene-therapy technology.

    “Once the virus is hidden in these reservoir cells, it becomes dependent on them: if the cell lives, the virus lives, but if the cell dies, so does the virus. As such, destroying these immune cells will allow for the elimination of the resilient or hidden parts of the virus,” says Dr Sekaly.

    While the team acknowledges that a product is still several years away before becoming a reality for patients, they are excited of the breakthrough which they say opens the way for therapies that are completely different from current ones.

    Nobility, Credibility morallity, humanity is more than remedy for HIV_AIDS. Penda utu wako. Linda utu wako. Penda Utu wa wengine na uliinde utu wa wote.

    Utu nifunguo wa mbingu pia?

    dawa gani zaidi.

    Ufie Utu wako na wa jamii Nzima..

    Utu is more powerfull than the HIV...??

    Lets be serious....na kuacha bla bla..

    Fruit and drugs on SA HIV display

    [​IMG] The government says it wants to highlight nutrition as well as drugs

    Lemons and garlic are displayed next to condoms and anti-retroviral drugs on the South African stand at Toronto's international Aids conference.
    Apples, nectarines and other tastier fruit were apparently included earlier, but were soon eaten, an official said.
    South Africa's health minister has long promoted a diet including garlic and lemon as a way of treating Aids.
    In 2004 the government began providing Aids drugs but activists still question its commitment to fighting HIV.
    The exhibition represents "South Africa's response to Aids - the most comprehensive in the world," an official at the stand told the BBC's Lee Carter.
    "The theme is talking about issues around nutrition, and also prophylaxis and treatment," he added.
    But the approach attracted controversy, particularly since the bottles of anti-retroviral drugs were only added to the stand some time after the fruit and vegetables went on display.
    One doctor from the paediatric Aids unit at Baragwanath Hospital in Soweto challenged the organisers of the exhibit to provide scientific evidence that any of the foodstuffs on display were clinically effective.
    "It's despicable that you bow to the minister's wishes and put the exhibit together in such a way," Dr Harry Moultrie said, quoted by Beeld newspaper.
    At the same time, a Southern African Development Community (SADC) report says the main reason for the spread of HIV/Aids is people who have multiple sexual partners and are not consistently using condoms.
    The study says casual sex and intercourse with sex workers are no longer the main causes of new HIV infections.
    It says traditional high-risk groups, such as prostitutes, mineworkers and truck drivers, are, in fact, better protecting themselves against infection.
