Gels to protect women from infection with the AIDS virus hold presented breaths that they may work, investigators stated on Mon.

But two surveys present that handses who take powerful HIV cocktails can still pass the virus on in their comes, even if it can not be happened in the blood.

The surveys exhibited at a meeting of AIDS in Canada show slow advancement in happening slipways to retard the pandemic of mortal hiv, which infects 33 million people globally and which holds killed 25 million.

Doctor Salim Abdool Karim of the Middle for the AIDS Plan of Research in Republic of south africa and workfellows essay a gel done by Massachusetts-based Indevus Pharmaceuticals named Professional 2000 in women.

They are seeking to encounter a microbicide a gel or pick that women and possibly handses can utilise to protect against the AIDS virus when their mates can not or will not utilise a rubber.

Professional 2000 trimmed the rate of HIV infection by a tertiary, they stated the meeting. `` This is the first survey that now presents that we hold a promising campaigner, '' Karim sayed a press conference.

`` We make not view it as a unequivocal decision that Professional 2000 is a microbicide but we certainly regard it equally really promising. ''

The investigators tried another microbicide named BufferGel done by ReProtect INC, but were unable to chance any important indicant that it assisted. The survey was merely planned to demo the gels were safe, an especially important issue because other surveys hold exhibited manque microbicides really raised the risk.

DRUGS AS PROTECTION

Two surveys in monkeys presented combinations of Gilead Sciences INC 's HIV drug Viread, or tenofovir, united with its newer drug emtricitabine, marketed under the marque Truvada, could protect monkeys from infection with a monkey virus similar to HIV both as a gel or in pills.

Dr. Gerardo Garcia-Lerma and workfellows at the U.S. Centers for Disease Control and Bar gave Viread and Truvada pills to monkeys in an attack named pre-exposure prophylaxis and bumped the monkeys were completely protected.

CDC 's Drs. Charles Dobard and Walid Heneine handled monkeys with one of two gels, one incorporating Viread exclusively and one with both drugs. Either gel worked as goodly in protecting the monkeys, they stated the meeting.

But two surveys exhibited that workforces who take highly active antiretroviral therapy cognized equally highly active antiretroviral therapy or HAART can still pass the virus in their seeds.

Prameet Sheth of the University of Toronto in Canada, and Anne-Genevieve Marcelin of the Pitie-Salpetriere in Paris, both encountered that manpowers whose blood appeared clear of HIV notwithstanding holded some in their comes.

`` I would reason that it is infective although we make n't cognize what grade of virus is necessitated, '' Sheth sayed the press conference.

The highly active antiretroviral therapy make not heal AIDS, but they make drive downwards grades of the virus to supposed undetectable grades in blood. This aids halt the virus from destruct the immune system and maintains patients healthy.

The hope holded been they would cut the spreading of AIDS, and on a population grade that may still be true, the investigators sayed the meeting.

But both squads chance when they examined single handses, they oft holded virus in their ejaculates, which intends they could infect soul else if they holded unprotected sex. It was not clear why the virus could be happened in cum but not in blood but experts cognise it is impossible to completely conquer the virus.
