percentage of CD4 cells
Aug 27, 2005

As usual you ignore a persons percentage and look at only T-cell count along with viral load. The person with 173,000 viral load and a T-cell count of 450 may have a pecentage below 14%. The fact you do not even address percentage in her question wiill make them angry if they get an AIDS diagnosis should the percentage drop. I have freinds I know with high T-cell counts who have had an Aids diagnosis because their percentage was below 14%. You need to Fully inform the public about percentage. Percentage is a better baraometer of ones imune system than T-cell counts!

Response from Dr. Pierone

I think that you are right the percentage CD4 count is important and often neglected. Although it is uncommon to develop an AIDS-related opportunistic infection with CD4 count above 200, this would be more likely in someone with a low CD4 percentage. I don't think that the natural history studies (in adults) support the statement that CD4 count percentage is a better barometer of immune function. But the percentage certainly adds important prognostic value to the laboratory assessment of HIV infection. Thanks for your comments.
