Lymphocyte Subpopulations in Spanish Parenteral Drug Addicts

Abstract
Lymphocyte subpopulations were studied in 29 symptom-free Spanish prisoners who were active parenteral drug abusers. In 16/29 drug addicts (55%) the helper-inducer/suppressor-cytotoxic ratio (Leu 3a/Leu 2a) was pppp<0.001) of Leu 7 positive cells (NK and K cells), but a normal percentage of B and phagocytic cells. Five drug addicts had generalized persistent lymphadenopathies, and 2 had skin anergy. We believe that most of the immunologic abnormalities seen in these apparently healthy drug abusers can be explained by an antigenic overload.
