Understanding CD4 Cells and CD4 Cell Tests

The Basics CD4 Count and HIV CD4 Count and HIV Treatment CD4 Cell Test The Bottom Line The Basics Your immune system protects your body by fighting germs and infections.White blood cells are an important part of your immune system. HIV infects and destroys a type of white blood cell called aCD4 cell (sometimes called a T-cell). As the immune system loses CD4 cells, it becomes weaker and is less able tofight off germs.

KS, Chemotherapy and CD4-Cells; How much of a hit will my CD4 cells take if I start chemotherapy?

I was recently told I have KS and am awaiting confirmation by biopsy. My cd4 count is about 200 and I have HEP B working on my liver. The first words out of the dr's mouth was chemo but I question that because of my cd4 count. I have not...

Although I can appreciate your concern that chemotherapy may suppress your CD4 count, I would like to give you some reassurance. Although I'm not sure what type of chemotherapy your oncologist will recommend, typically we start with liposomal... Read more »

You don't indicate whether you are taking HIV meds. If not, you should be. However, that is unlikely to be a significant decrease in your CD4 count, given that your CD4 percent has not changed. The CD4 count is much more variable, and can vary... Read more »

If HIV kills CD4 cells that present themselves, can high CD4 levels in first years of infection later result in faster progression to AIDS?

Dr. Holodniy, I am searching for the right words, but have an important question:It is often assumed that the more CD4 cells in a T cell subset, the better. But,in that the more CD4's that present themselves, the more for HIV to kill, could...

Not alot of studies on this issue. It is usually assumed that those infected people with such high CD4 counts, usually have low or undetectable viral loads, indicating an immune system with better capability to contain viral replication. It has... Read more »

stagant CD 4 or slow increase in CD 4 cells over a few years.

could you let me know what if my CD4 still hangs around between 200 plus to 300 plus in over 5 years or more but never reaches 400 which has to meet the average of 500 to be on the safe side ? Does it mean that my body will wear out and then I will...

If you are on HIV treatment and your viral load is undetectable, and you maintain CD4 counts between 200-300, then you are still at risk, although at a reduced level, for HIV associated complications. The risk is still greater at 200-300, then it is... Read more »

What Is a T-Cell or CD4 Count?

Your T-cell count, also known as a CD4 count, reveals the number of T cells in your body. A T cell is a special kind of white blood cell, and the more you have, the stronger your immune system is. When you were infected... Read more »
