31.   The study was one of the first to use measurements of viral load and at the same time it measured clinical endpoints, meaning AIDS events or death.

33.   The significance to patients of changes in HIV viral load has not been fully established, Roche said.

34.   The viral loads have been reduced to undetectable in the remaining subjects.

35.   They are all so thrilled about having their viral loads down to nondetectable.

36.   Three still have undetectable viral loads, but the other three now have detectable virus and decreasing immune cells.

37.   Waiting until there is definite proof that reducing viral load will save lives is not seen as an option.

38.   Viral load is also a good predictor of how long someone with HIV is likely to live.

39.   After the transplant, Getty said his viral load, the amount of HIV virus in his blood, dropped to zero and his immune system got stronger.

40.   Later this year, the researchers said they would take the three men off of the drug cocktail therapy to see if their viral loads increase again.
