The WHO recently announced that antiretroviral drugs as the only highly effective drugs to fight HIV / AIDS disease if taken regularly. But fears of resistance (immunity) drugs are now pricking.
Concerns arose after researchers from the University of California, the University of Tennessee and the University of Ottawa analyzed data on the use of antiretroviral drugs (ARVs) in San Francisco since 1987.
By using a special calculation model of drug resistance, it is known that the citizens of San Francisco that have anti-viral drug treatment continuously or excessive, having the immune system drugs and imunnya no significant increase. Times reported: "Based on the experimental model we make, drug resistance will menigkat approximately 30 percent of 3 to 5 years from now," said Sally Blower, a professor from the David Geffen School of Medicine, University of California.
But so far there has been no damage to the body's immune system due to antiretroviral drug resistance, WHO said it will not attract drug often prescribed to people with HIV are.
"But still WHO should anticipate this, especially in developing countries. This is a reminder for researchers to immediately issue an HIV vaccine," said Jim Kahn, expert and professor of medicine from the University of California, San Francisco.
Whatever happens, the study published in this journal Science says that the handling of HIV in the future will be increasingly difficult and expensive. For that, as long as there is no vaccine, should avoid the risk factors of transmission such as the use of non-sterile needles and unsafe sex.
