I am looking for information about how many people stop azt therapy, and why. How long does viral resistance sufficient to warrant stopping azt take to set in? How long does it take for side effects to make the drug intolerable? How many people stop taking the drug after political realizations about the Burroughs-Wellcome Company?Basically, how many people stop taking azt, and after how long? An editorial in the Providence Journal indicated that Dr. Douglas Richman of UC San Diego found that viral resistance to azt seems to develop within six months. I would appreciate a published reference to Dr. Richman's work. Looking for info on the topic, I found an article dating from Dec 1, '89 in Science by BA Larder et al. which states: Most isolates from patients with AIDS or ARC who were treated for 6 months or more showed reduced sensitivity to zidovudine [azt], whereas isolates from untreated individuals and those treated for less than 6 months showed uniform sensitivity to the drug. While the study indicates that, in its small population, resistance to azt built up relatively quickly, I'm not sure that this means that the resistance was strong enough to make treatment with azt useless after 6, 12, 18 months or longer. Perhaps someone can shed light on this problem. Be well and stay strong, Bill Jesdale, ActUp/RI & RI Dep't of Health Box 5342, Brown U, Prov, RI 02912 Ph: 401/421-4687 st501020@BROWNVM
