Today, all that is associated with HIV is incredibly important. Indeed, despite the deployed throughout the world of preventive company, the virus human immunodeficiency continues its lethal march, and his victims, unfortunately, is becoming more. And they, alas, younger, according to the statistics.
Talk about viral load of HIV. What it is? This is actually the amount of HIV in the patient's blood. And any HIV treatment is aimed at in order to reduce this burden, to make sure that the amount of HIV in the blood has decreased so much that it would be impossible to determine by laboratory methods.
Important! For HIV-infected need to know their own viral load at least to know how effective their antiretroviral therapy (ie, treatment).
Thus, HIV attacks the T-cells (CD4) - white blood cells that are an important part of the immune system of any person. A laboratory CD4 count gives an idea of how a healthy immune system to date. If a person is not a carrier of HIV, the number of CD4 cells, it ranges from 500 to 1500.
The formula is simple: high viral load leads to reduction of CD4 cells. And when it is below 200, it increases the risk of complications of HIV infection. After a small number of white blood cells significantly complicates the fight against any infectious disease, and human immunodeficiency virus - is no exception. In parallel, increasing the risk of developing certain types of cancer.
If HIV is not treated at all (to avoid antiretroviral therapy), the virus goes into complications that are difficult to any whatsoever treatment. And then probably develop into AIDS. But if prescription drugs are taken daily, the number of CD4 cells gradually begin to increase. Body's immune system becomes stronger and stronger, and thus increases the ability of man to fight infections.
Summarizing, we can say that the study on the number of T-cells (CD4) - an important component of HIV therapy, It allows you to control how well this is the therapy is working for a particular patient. How efficiently killed HIV in the blood and thus restores the immune system. Ideal results antiretroviral therapy - to achieve an undetectable viral load at the same time the high number of CD4-cells.
