Staging of HIV Patients from Immunophenotypes |
1. Introduction:
HIV disease is characterized by the gradual fading of the
immune response resulting in an increased susceptibility for
life threatening opportunistic infections.
- Flow cytometric immunophenotype measurements of lymphocyte surface antigen
patterns are performed with the concept to obtain information on
the current status of the immune system. The antigen patterns are
determined by flow cytometry following simultaneous staining of peripheral
blood leukocytes with two or three fluorescinated antibodies against CD
clustered antigens.
- Although a high variety of measurements with many different antigen
combinations has been performed by a multitude of groups, only few
determinations like the number of CD4 positive cells are considered
of clinical importance.
2. Goal: It was the goal of this work to utilize all available information in an attempt to clinically stage HIV patients.
3. CLASSIF1 Data Pattern Classification: standardized and automated classification of two or three color immunophenotype measurements with the CLASSIF1 program system.
4. Conclusion The results indicate that individual patient staging is possible by simultaneous consideration of all lympho-, mono- and granulocyte immunophenotype properties. It is also possible to discriminate seronegative persons with a risk life style from normal individuals. This may permit to screen for an increased susceptibility to HIV infection by clinical cytomics.
