Prospects in AIDS Research 2006
Dr. Luc Montagnier
Since the discovery of HIV,the causative agent of AIDS ,important
advances in this field have been made:prevention of the transmission
of the agent by blood transfusion and blood products- thanks
to reliable tests of HIV infection-implementation of rational
prevention measures against the transmission by sexual contacts
and drug abuse.And,since 1996 clinical use of a combination
of specific inhibitous active on the virus multiplication,reverse
transcriptase and protease inhibitors.The advent of this triple
therapy has changed the status of HIV infection from a deadly
disease,decreasing by 90% the risk of death by opportunistic
infections and cancers.
However,important problems are still acute:
1)This treatment does not cure the infection and,so far,has
to be given lifelong.Side effects and risks of emergence of
resistant mutants are high in the long term of use of these
drugs.
2)It has not yet been made available to all patients of the
developing world.cost and difficulty of implementation in
these countries are limiting factors of their expansion.
3)Prevention by information and education has a limited impact,since
no treatment is proposed at the onset of HIV infection,and
therefore,there is no incitement for HIV testing.Only a minor
fraction of asymptomatic HIV infected patients know that they
are HIV positive and are responsibilized for avoiding the
transmission of the virus.
4)No medical ways of prevention have been successful so far.
As a result,despite many efforts at the national and international
level,the epidemic is still spreading and can make the bed
to the re-emergence of other infectious agents.Resrarch efforts
must be directed at finding new ways of treatments which could
complement the trement presently in use:antioxidants,immunostimulants
and therapeutic vaccines.Preventive vaccines using the native
surface protein of HIV have failed.Genetically made changes
of the conformation of this protein.exposing to the immune
system its more conserved parts,are more promising.
