New research from Boston reveals that some AIDS patients can control their disease when triple-drug therapy is temporarily stopped. Researchers from Massachusetts General Hospital reported preliminary findings from two patients who were on "structured interrupted therapy" at a meeting of the Infectious Disease Society of America in Philadelphia this weekend. The scientists noted that while HIV came back each time the drugs were halted, there were signs the patients' immune systems were fighting to control the virus, with growing success. While it is still too early to know if some patients will be able to discontinue taking AIDS drugs as a result of this experiment, the findings are encouraging and other leading research centers have started similar studies or a planning to conduct them.
