Response from Dr. Little

I share your concern - although I cannot explain your drug resistance test (which showed no resistance) - I would be very concerned that you are developing 3TC or sustiva resistance. Although your T cells look great - it is typical that changes in the CD4 cell count may lag 8-12 weeks after changes in viral load. So - not seeing a T cell drop does not bother me nearly as much as seeing a consistent rise in your viral load. I would consider intensifying your antiretroviral therapy to create a more potent regimen - or changing it altogether if drug resistance is still a major concern (i.e. you could change it and send a repeat drug resistance test at the same time). Either way, I would not feel comfortable waiting until feb. for another set of tests.
