- AB Assessment of the CD4 lymphocyte number, currently performed by flow
- cytometry, is one of the main laboratory tests for establishing
- progression to acquired immunodeficiency syndrome (AIDS). An enzyme
- immunoassay has recently been commercialized which can be very useful
- for counting CD4 cells in laboratories where flow cytometers are not
- available. In the present study, a comparative evaluation of CD4
- positive lymphocytes with flow cytometry and the enzyme assay was made
- in healthy subjects (N = 30, R = 0.88, P < 0.0001), human
- immunodeficiency virus (HIV)-infected individuals (N = 80, R = 0.91, P <
- 0.0001), and patients with autoimmune diseases (N = 28, R = 0.82, P <
- 0.001) or psoriasis (N = 18, R = 0.76, P = 0.01). A correlation between
- the two methodologies was not found in psoriatic patients under
- treatment with cyclosporin A (N = 7, R = 0.05, not significant). Some
- differences could be found at low CD4 lymphocyte levels since the
- influence of CD4 antigen eluted from monocytes or soluble CD4 in the
- whole blood sample could cause overestimation of CD4 cell numbers by the
- enzyme assay.
