Persistent unexplained lymphadenopathy with intermittent fever, weight loss, night sweats and malaise was observed in the period from March 1983 to April 1984 in 66 intravenous drug addicts living in Milan. A high percent of these subjects showed cellular immunity alterations, with significant decrease of total lymphocyte count (p less than 0.001) and of OKT4+ cells (percent and absolute number) (p less than 0.001) OKT8+ cells were augmented in percent, but not in absolute count. OKT4/OKT8 cell ratio were inverted, with significant reduction versus the healthy controls (p less than 0.001). IgG mean concentrations were significantly higher than the normal (p less than 0.001). Anergy or hypoergy to recall skin testing were evidenced in 58/66 patients. Cases of persistent unexplained lymphadenopathy associated with abnormalities of cellular immunity are considered as a possible prodrom of AIDS and were frequently observed in high risk populations. The occurrence of this clinical syndrome in a urban area may be premonitory of further progression to the epidemic. It will be necessary to assess whether this clinical and immunological picture will result in some of these patients in full blown acquired immunodeficiency syndrome.
