Link Found Between AIDS Antibodies and Disease Risk
A Boston study in the New England Journal of Medicine reports that HIV infected individuals with low AIDS antibody levels face higher short term risk of developing AIDS. Researchers identify five predictive factors including antibody levels, T helper and T suppressor cells, cytomegalovirus antibodies, and prior exposure to AIDS. The work, led by Dr. B Frank Polk, suggests antibody response may be protective though no treatment exists to stop AIDS yet.
