AIDS Update

Course Description

It was spring of 1996 when Beth Bye says she returned from the dead. The Wisconsin woman hadn’t actually died, but with her body ravaged in the late stages of AIDS infection, she had run out of options, and death was, indeed, near. AIDS-related dementia and blindness had crept in-signs that her doctor told her meant time was short. She made funeral arrangements and considered moving to a hospice for her remaining days.

Then, as if to say “not so fast,” medical science handed her another option. New drugs called pro¬tease inhibitors, first approved in 1995, were about to revolutionize the treatment of patients in¬fected with the AIDS virus. These drugs usually are taken with two other drugs called reverse transcriptase inhibitors. The combined drug “cocktail” has helped change AIDS in the last three years from being an automatic death sentence to what is now often a chronic, but manageable, disease.

Within two months of beginning the triple cocktail treatment, also known as highly active antiretroviral therapy (HAART), Bye’s viral load-a measure of new AIDS virus produced in the body-dropped to undetectable levels. Her red and white blood cell counts normalized, an impor¬tant sign that the immune system was starting to work again. Suddenly she could do simple things she had long given up, such as walk the dog for 2 miles. Bye, now 40, was even able to return to her teaching job and currently works 30 hours a week.

“My recovery was like being on death row and getting that last-minute pardon from the governor,” she says.

This so-called “Lazarus Effect,” named for the biblical figure who was raised from the dead, has occurred with many AIDS patients who take the triple therapy. “It returns many who were debili¬tated and dying to relatively healthy and productive life,” says Richard Klein, HIV/AIDS coordina¬tor for the Food arid Drug Administration’s Office of Special Health Issues.

In 1997, for the first time since 1990, AIDS fell out of the top 10 causes of death in the United States, dropping from 8th to 14th place, according to the national Centers for Disease Control and Prevention. By 1998, about 16,000 people were still alive who would have died the previous year if AIDS mortality had continued at its former rate. Still, about 40,000 new infections occur yearly.
