Infection With 2 HIV Strains Slows Disease Progression

WEDNESDAY, July 18 (HealthDay News) -- While many people don't know it, there's more than one kind of AIDS virus. Besides the HIV-1 strain that's common throughout the world, a type known as HIV-2 is found in some parts of Africa. Now, a new study finds that people infected with HIV-2 and later with HIV-1 appear to be better equipped to fight off the virus.

Double-infected people can still go on to develop AIDS, and there's no indication that anyone infected with HIV-1 should go out in search of HIV-2.

However, "this study should prompt researchers to take a fresh look at HIV-2 infection" and why it seems weaker, and the potential implications for a vaccine, said Sarah Rowland-Jones, an AIDS specialist and professor of immunology at John Radcliffe Hospital in Oxford, England.

The big questions, she said, are these: Is there something about the HIV-2 virus that makes it less dangerous to the human body's immune system defenses? Or is it perhaps the other way around, and the body's defenses are the key?

"If we understood this, it would have a lot of relevance for HIV vaccine design," said Rowland-Jones, who's familiar with the new study's findings.

The HIV-2 strain is largely found in West Africa and hasn't spread much beyond there, although there have been cases reported in Europe, India, Japan and the United States, Rowland-Jones said. Many people who are infected with the HIV-2 virus develop AIDS and die, but some live normal lives, she said.

The new study looked at West Africans in the country of Guinea-Bissau and focused on 223 people who first became infected with HIV-2 and then with HIV-1 or those who only got the HIV-1 strain.

The researchers tracked the patients for about 20 years. They found that it took an average of 104 months (nine years) for those with dual infections to develop AIDS, but just 68 months (nearly six years) for those infecte
