Thank you in advance for your valuable time. This is a very helpful and comforting service. I have a few questions in regard to facial-wasting: My doctor says that in his "heart of hearts" he feels that switching-off Zerit will not really improve my situation. (Though I've read testimonials to the contrary.) My wasting began a year ago, yet thankfully seems to have leveled-off in the last 6 months. The somewhat gaunt appearance is disturbing, but has NOT worsened (and I can live with that.) Is this a normal trend, or will there be more deterioration with time? I understand that there is some data (not much) claiming that "New" Zerit may help counter this problem? Any insight is greatly appreciated.
Response from Dr. Boyle
Some studies indicate that many patients who develop wasting reach a plateau level and then do not progress significantly. Whether or not the plateau you have reached is a pause or an end of the progression is tough to say. As far as the benefits of switching off Zerit (stavudine), I'm not in complete agreement with your doctor. Several studies have shown some improvement in fat loss when Ziagen (abacavir) is substituted for Zerit. Now, some of this improvement is sub-clinical (meaning that neither you nor your doctor may be able to notice it), but some may result in an improvement in your physical appearance. Still, you must balance the success you have had with Zerit against the risks of switching to abacavir, one of which is the risk of a hypersensitivity reaction that occurs in about 10% of patients. As far as the risk of the "new" Zerit, meaning Zerit XR, this is presently still in question, although some preliminary data indicate a trend toward lower rates of fat loss and neuropathy with the XR (once-daily) formulation.
