CD4 % trend
May 6, 2011
These are my lab results from when I was first diagnosed as HIV+
8/26/2009 CD4 66 CD4/100 cells 3 VL 29956 9/14/2009 CD4 169 CD4/100 cells 8 VL 2249 10/7/2009 CD4 252 CD4/100 cells 9 VL 458 11/16/2009 CD4 298 CD4/100 cells 10 VL <75 2/8/2010 CD4 263 CD4/100 cells 12 VL <75 5/13/2010 CD4 329 CD4/100 cells 12 VL <48 7/19/2010 CD4 338 CD4/100 cells 13 VL <48 10/29/2010 CD4 467 CD4/100 cells 16 VL <48 1/31/2011 CD4 328 CD4/100 cells 15 VL <48 5/2/2011 CD4 442 CD4/100 cells 14 VL <48
My question is even though my CD4 count is trending up, my CD4/100 % was trending up from 3 in August 2009 to 16 in October 2010. Ever since then is has been trending down to 15 in January 2010 and 14 now. I've been taking Atripla since I was diagnosed. I've read that the CD4 % is a more accurate measure than the actual CD4 count, so since it's trending down do you think that there is any reason for concern? Do you think that the Atripla might not be working as well as it should be? Can you think of any reason why my CD4 % peaked and now is trending back down? I feel fine and my ID doctor with Kaiser Permanente doesn't seem concerned.

Hello and thanks for your post.
I agree with your KP doctor-- your numbers look very good and show enormous improvement from where you started. Small variations, 1-2% probably have no particular meaning, especially since your viral load remains undetectable. Indeed, it's this last aspect that is singularly the most sensitive measure of whether or not your HIV medications (Atripla) is working or not.
I hope that helps. BY
