[Classification of HIV-associated acquired immunologic deficiency syndrome]

Regarding the staging of HIV infection, there are several classification systems, but neither of them has universally been accepted. We tested a new staging system with 4 parameters: HIV antibodies, CD4/CD8 ratio, absolute count of CD4 + lymphocytes, and absolute count of leukocytes. This classification indicates a regular progression of immunodeficiency, 294 blood specimens were used for immunological staging. The correlation between the immunological staging and the severity of the disease proved the usefulness of this classification system.
